My Philosophy of Education Essay -- Philosophy of Education Statement

Philosophy of Education What is my philosophy of education? For hours I have tried to decide what exactly that is. However after much thought I have not been able to come up with an exact answer. After much consideration I have decided that I have no real philosophy but I have goals that one day I will achieve. Although the goals sound simple I know that they will be difficult to attain. I have almost always wanted to teach. I grew up in a single parent household and my mother was an elementary school teacher. When I was younger I didn’t really appreciate what my mom was doing for her students. I only liked what it meant for me. I was allowed to leave with my mother at lunchtime and go out to eat, and I always received special privileges like using the principal’s computer. However as years passed I began to see the impact my mother had on students. Peers in high school would always tell me that my mother was their favorite teacher or how she sparked an interest in a specific subject or how she helped to understand a difficult subject. Therefore, my mother has always been an influence on why I wanted to teach. Even today when my mother asks or when I have time to I will go help her with school functions, classroom projects, or assistance in anything else my mother might require of me. Another reason I wanted to teach is because of the teachers I had in high school. I saw how respected and approachable they were, and ho...

The Return: Nightfall Chapter 23

Acoldfrisson went down Elena's back, the most delicate of shivers. Damon didn'task for kisses. This wasn'tright . â€Å"No,† she whispered. â€Å"Just one.† â€Å"I'm not going to kiss you, Damon.† â€Å"Not me. Him.† Damon denoted â€Å"him† with a tilt of his head toward Matt. â€Å"A kiss between you and your former knight.† â€Å"You wantwhat ?† Matt's eyes snapped open and he got the words out explosively before Elena could open her mouth. â€Å"You'd like it,† Damon's voice had dropped to its softest, most insinuating tones. â€Å"You'd like to kiss her. And there's no one to stop you.† â€Å"Damon.† Matt struggled up out of Elena's arms. He seemed, if not entirely recovered, perhaps eighty percent of the way there, but Elena could hear his heart laboring. Elena wondered how long he'd lain feigning unconsciousness to get his strength back. â€Å"The last thing I knew you were trying to kill me. That doesn't exactly get you on my good side. Second, people just don't go around kissing girls because they're pretty or their boyfriend takes a day off.† â€Å"Don't they?† Damon hiked an eyebrow in surprise. â€Å"I do.† Matt just shook his head, dazed. He seemed to be trying to keep one idea fixed in his mind. â€Å"Will you move your car so we can leave?† he said. Elena felt as if she were watching Matt from very far away; and as if he was caged somewhere with a tiger and didn't know it. The clearing had become a very beautiful, wild, and dangerous place, and Matt didn't know that either. Besides, she thought with concern, he'smaking himself stand up. Weneed to leave – and quickly, before Damon does anything else to him. But what was the real way out? What was Damon's real agenda? â€Å"You can go,† Damon said. â€Å"As soon as she kisses you. Or you kiss her,† he added, as if making a concession. Slowly, as if he realized what it was going to mean, Matt looked at Elena and then back at Damon. Elena tried to communicate silently with him, but Matt wasn't in the mood. He looked Damon in the face and said, â€Å"No way.† Shrugging, as if to say,I did everything I could , Damon lifted the shaggy pine rod – â€Å"No,† cried Elena. â€Å"Damon, I'll do it.† Damon smiledthe smile and held it for a moment, until Elena looked away and went to Matt. His face was still pale, cool. Elena leaned her cheek against his and said almost soundlessly into his ear, â€Å"Matt, I've dealt with Damon before. And you can't just defy him. Let's play along – for now. Then maybe we can get away.† And then she made herself say, â€Å"For me? Please?† The truth was that she knew too much about stubborn males. Too much about how to manipulate them. It was a trait she'd come to hate, but right now she was too busy trying to think of ways to save Matt's life to debate the ethics of pressuring him. She wished it were Meredith or Bonnie instead of Matt. Not that she would wish such pain on anyone, but Meredith would be coming up with Plans C and D even as Elena came up with A and B. And Bonnie would already have lifted tear-filled, heart-melting brown eyes to Damon†¦. Suddenly Elena thought of the single red flash she'd seen under the Ray-Bans, and she changed her mind. She wasn't sure she wanted Bonnie around Damon now. Of all of the guys she'd known, Damon had been the only one Elena couldn't break. Oh, Matt was stubborn, and Stefan could be impossible sometimes. But they both had brightly colored buttons somewhere inside them, labeledPUSH ME , and you just had to fiddle with the mechanism a little – okay, sometimes more than a little – and eventually even the most challenging male could be mastered. Except one†¦ â€Å"All right, kiddies, enough time out.† Elena felt Matt pulled from her arms and held up – she didn't know by what, but he was standing. Something held him in place, upright, and she knew it wasn't his muscles. â€Å"So where were we?† Damon was walking back and forth, with the Virginia pine branch in his right hand, tapping it on his left palm. â€Å"Oh, that'sright † – as if making a great discovery – â€Å"the girl and the stalwart knight are going to kiss.† In Stefan's room, Bonnie said, â€Å"For the last time, Meredith, did you find a backup file for Stefan's note or not?† â€Å"No,† Meredith said in a flat voice. But just as Bonnie was about to collapse again, Meredith said, â€Å"I found a different note completely. A letter, really.† â€Å"Adifferent note? What does it say?† â€Å"Can you stand up at all? Because I think you'd better have a look at this.† Bonnie, who had only just gotten back her breath, managed to hobble over to the computer. She read the document on the screen – complete except for what seemed to be its final words, and gasped. â€Å"Damon did something to Stefan!† she said, and felt her heart plummet and all her internal organs follow it. So Elena had been wrong. Damonwas evil, through and through. By now, Stefan might even be†¦ â€Å"Dead,† Meredith said, her mind obviously following the same track that Bonnie's had taken. She lifted dark eyes to Bonnie's. Bonnie knew that her own eyes were wet. â€Å"How long,† Meredith asked, â€Å"has it been since you called Elena or Matt?† â€Å"I don't know; I don't know what time it is. But I called twice after we left Caroline's house and once at Isobel's; and when I've tried after that, I either get a message that their mailboxes are full or it won't connect at all.† â€Å"That's about exactly what I've gotten. If they went near the Old Wood – well, you know what it does to phone reception.† â€Å"And now, even if they come out of the woods, we can't leave them a message because we've filled up their voicemail – â€Å" â€Å"E-mail,† Meredith said. â€Å"Good old e-mail; we can use that to send Elena a message.† â€Å"Yes!† Bonnie punched the air. Then she deflated. She hesitated for an instant and then almost whispered, â€Å"No.† Words from Stefan's real note kept echoing in her mind:I trust Matt's instinctive protectiveness for you, Meredith's judgment, and Bonnie's intuition. Tell them to remember that. â€Å"You can't tell her what Damon's done,† she said, even as Meredith began busily typing. â€Å"She probably already knows – and if she doesn't, it'll just make more trouble. She's with Damon.† â€Å"Matt told you that?† â€Å"No. But Matt was out of his mind with pain.† â€Å"Couldn't it have been from those – bugs?† Meredith looked down at her ankle where several red welts still showed on the smooth olive flesh. â€Å"It could be, but it wasn't. It didn't feel like the trees, either. It was just†¦pure pain. And I don't know, not for certain, how I know that it's Damon doing it. I just – know.† She saw Meredith's eyes unfocus and knew that she was thinking about Stefan's words, too. â€Å"Well, my judgment tells me to trust you,† she said. â€Å"By the way, Stefan spells  ¡Ã‚ ®judgment' the preferred American way,† she added. â€Å"Damon spells it with ane . That may have been what was bothering Matt.† â€Å"As if Stefan would really leave Elena alone with everything that's been going on,† Bonnie said indignantly. â€Å"Well, Damon fooled all of us and made us think so,† Meredith pointed out. Meredith tended to point out things like that. Bonnie started suddenly. â€Å"I wonder if he stole the money?† â€Å"I doubt it, but let's see.† Meredith pulled the rocking chair away, saying, â€Å"Grab me a hanger.† Bonnie grabbed one from the closet and grabbed herself one of Elena's tops to put on at the same time. It was too big, since it was Meredith's top given to Elena, but at least it was warm. Meredith was using the hooked end of the wire hanger on all sides of the floorboard that looked most promising. Just as she managed to pry it up, there was a knock at the open door. They both jumped. â€Å"It's only me,† said the voice of Mrs. Flowers from behind a large duffel bag and a tray of bandages, mugs, sandwiches, and strong-smelling cheesecloth bags like the ones she'd used on Matt's arm. Bonnie and Meredith exchanged a glance and then Meredith said, â€Å"Come in and let us help you.† Bonnie was already taking the tray, and Mrs. Flowers was dumping the duffel bag on the floor. Meredith continued prying the board up. â€Å"Food!† Bonnie said gratefully. â€Å"Yes, turkey-and-tomato sandwiches. Help yourselves. I'm sorry I was away so long, but you can't hurry the poultice for swellings,† Mrs. Flowers said. â€Å"I remember, long ago, my younger brother always said – oh, my goodness gracious!† She was staring at the place where the floorboard had been. A good-sized hollow was filled with hundred-dollar bills, neatly wrapped in packets with bank-bands still around them. â€Å"Wow,† Bonnie said. â€Å"I never saw so much money!† â€Å"Yes.† Mrs. Flowers turned and began distributing cups of cocoa and sandwiches. Bonnie bit into a sandwich hungrily. â€Å"People used to simply put things behind the loose brick in the fireplace. But I can see that the young man needed more space.† â€Å"Thank you for the cocoa and sandwiches,† Meredith said after a few minutes spent wolfing them down while working on the computer at the same time. â€Å"But if you want to treat us for bruises and things – well, I'm afraid we just can't wait.† â€Å"Oh, come.† Mrs. Flowers took a small compress that smelled to Bonnie like tea and pressed it to Meredith's nose. â€Å"This will take the swelling down in minutes. And you, Bonnie – sniff out the one that's for that bump on your forehead.† Once again Meredith's and Bonnie's eyes met. Bonnie said, â€Å"Well, if it's only a few minutes – I don't know what we're doing next anyway.† She looked the poultices over and picked a round one that smelled of flowers and musk to put on her forehead. â€Å"Exactly right,† Mrs. Flowers said without turning around to look. â€Å"And of course, the long thin one is for Meredith's ankle.† Meredith drank the last of her cocoa, then reached down to gingerly touch one of the red marks. â€Å"That's okay – † she began, when Mrs. Flowers interrupted. â€Å"You're going to need that ankle at full capacity when we go out.† â€Å";;When we go out'?† Meredith stared at her. â€Å"Into the Old Wood,† Mrs. Flowers clarified. â€Å"To find your friends.† Meredith looked horrified. â€Å"If Elena and Matt are in the Old Wood, then I agree:we have to go look for them. Butyou can't go, Mrs. Flowers! And we don't know where they are, anyway.† Mrs. Flowers drank from the cup of cocoa in her hand, looking thoughtfully at the one window that wasn't shuttered. For a moment Meredith thought she hadn't heard or didn't mean to answer. Then she said, slowly, â€Å"I daresay you all think I'm just a batty old woman who's never around when there's trouble at hand.† â€Å"We would never think that,† Bonnie said staunchly, but thinking that they'd found out more about Mrs. Flowers in the last two days than in the entire nine months since Stefan had moved in here. Before that, all she'd ever heard were ghost stories or rumors about the crazy old lady in the boardinghouse. She'd been hearing them since she could remember. Mrs. Flowers smiled. â€Å"It's not easy having the Power and never being believed when you use it. And then, I've lived for so long – and people don't like that. It worries them. They start to make up ghost stories or rumors – â€Å" Bonnie felt her eyes go round. Mrs. Flowers just smiled again and nodded gently. â€Å"It's been a real pleasure having a polite young man in the house,† she said, taking the long poultice from the tray and wrapping it around Meredith's ankle. â€Å"Of course, I had to get over my prejudices. Dear Mamaalways said that if I kept the place, I might have to take in boarders, and to be sure not to take in foreigners. And then of course, the young man is a vampire as well – â€Å" Bonnie almost sprayed cocoa across the room. She choked, then went into a spasm of coughing. Meredith had her no-expression expression on. † – but after a while I got to understand him better and to sympathize with his problems,† Mrs. Flowers continued, ignoring Bonnie's attack of coughing. â€Å"And now, the blond girl is involved as well†¦poor young thing. I often speak to Mama† – still with the accent on the second syllable – â€Å"about it.† â€Å"How old is your mother?† Meredith asked. Her tone was one of polite inquiry, but to Bonnie's experienced eyes her expression was one of slightly morbid fascination. â€Å"Oh, she died back at the turn of the century.† There was a pause, and then Meredith rallied. â€Å"I'm so sorry,† she said. â€Å"She must have lived a long – â€Å" â€Å"I should have said, the turn of theprevious century. Back in 1901, it was.† This time it was Meredith who had the choking fit. But she was more quiet about it. Mrs. Flowers' gentle gaze had drifted back to them. â€Å"I was a medium in my day. On vaudeville, you know. So hard to achieve a trance in front of a roomful of people. But, yes, I really am a White Witch. I have the Power. And now, if you've finished your cocoa, I think it's time we went into the Old Wood to find your friends. Even though it's summertime, my dears, you'd both better dress warmly,† she added. â€Å"I have.†

MERITS 8. CONCLUSION 9. REFERENCES ABSTRACT RFID (Radio Frequency Identification) is the quintessential pervasive computing technology. The heart of the utility is that RFID makes gathering information about physical objects easy.Information about RFID tagged objects can be read through physical barriers, and from a distance. Our project utilized these RFID tags to improve the security system of a building by introducing a system that could read the RFID tagged smart cards that are placed in proximity to an antenna. Our project comes with option of finger print system, GSM system and camera system attached with the main RFID system. This help in making the security full proof and reduce the possibility of breaches. RFID devices have three primary elements: a chip, an antenna, and a reader.A fourth important part of any RFID system is the database where information about tagged smart card is stored. For wireless data transmission and networking between sensor nodes, the project uses ZigBee modules. The modules require minimal power and provide reliable delivery of data between devices with efficient security measures. This project is implemented in real time system. INTRODUCTION The major problem faced by organizations in security breach is related with doors without proper security system on them for their protection. Our project is going to solve these problems by using RFID technology.For wireless data transmission between tag and sensor nodes, the project uses ZigBee modules. Radio Frequency Identifica tion (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. So the RFID is a wireless identification. Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag. RFID Reader is an integrated or passive network which is used to interrogate information from RFID tag (contains antennas to enable them to receive and respond to radiofrequency queries from an RFID transceiver).The RFID Reader may consist of antenna, filters, modulator, demodulator, coupler and a micro processor. We try to enhance the security up to a very effective level so that there are minimum possibilities in the security breach. For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. The system also creates a log containing check-in and check-out of each user along with basic information of user. OBJECTIVEThe aim of the project is to design a system that have a small coverage area and can be use for authentication or identification purposes. â€Å"Security System Using RFID† is a system that uses RFID technology to maintain the security of the different rooms in same structure which can be monitored on real-time bases using the Database server (PC). This system prevents unauthorized entry in rooms. For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. This ensures the reliability of the system and makes it difficult to breach.SYSTEM ANALYSIS EXISTING SYSTEM In the existing system, Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that â€Å"wakes up† the tag and provides the power for the tag to respond to the reader. Data collected from tags is then passed through co mmunication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action.The drawback in this system is the lack of security option available for the user. One can easily use others RFID tag to gain access in the desired place without their prior knowledge. This breach cannot be easily accounted as there is no record other then the RFID tag used which can mislead to undesirable situation. PROPOSED SYSTEM This system is of new kind in which finger print recognition system along with GSM and camera is newly added. In this system RFID along with ZigBee, microcontroller, biometric system, GSM, amplifier circuit, power supply, camera and database server (PC) is used.Different circuits work together to form an unreachable system so that the security can be enhanced to the maximum level possible. When RFID tag is sensed by the RFID receiver and finger prin t impression is given, the camera is activated which clicks the image of the user trying to access the system. This information is stored in the database along with time and date when the system was accessed and the GSM technology used in the system make sure that the concerned authority is notified about the activation of the system along with result.

Visual Basic is relatively easy to learn and use.Vi sual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects. Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but perform differently. A programmer can put together an application using the components provided with Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations.Visual basic is used to provide a simple interface about the program between user and system software. This is also used for storing the data and act as database for the system. MIKRO BASIC MikroBasic is a powerful, feature rich development tool for PIC microcontrollers. It is designed to provide the customer with the easiest possible solution for developing applications for embedded systems , without compromising performance or control. Highly advanced IDE, broad set of hardware libraries, comprehensive documentation, and plenty of ready to run example programs should be more than enough to get you started in programming microcontrollers.FEATURES MikroBasic allows you to quickly develop and deploy complex applications: †¢Write your BASIC source code using the built-in Code Editor (Code and Parameter Assistants, Syntax Highlighting, Auto Correct, Code Templates, and more†¦) †¢Use the included mikroBasic libraries to dramatically speed up the development: data acquisition, memory, displays, conversions, communications†¦ Practically all P12, P16, and P18 chips are supported. †¢Monitor your program structure, variables, and functions in the Code Explorer. Generate commented, human-readable assembly, and standard HEX compatible with all programmers. †¢Inspect program flow and debug executable logic with the integrated Debugger. †¢Get detai led reports and graphs: RAM and ROM map, code statistics, assembly listing, calling tree, and more†¦ †¢We have provided plenty of examples for you to expand, develop, and use as building bricks in your projects. Copy them entirely if you deem fit – that’s why we included them with the compiler. HARDWARE DESCRIPTION RFID TAGS Tags also sometimes are called â€Å"transponders†. RFID tags can come in many forms and sizes.Some can be as small as a grain of rice. Data is stored in the IC and transmitted through the antenna to a reader. The two commonly used RFID Transponders [2] are Active (that do contain an internal battery power source that powers the tags chip) and passive (that does not have an internal power source, but are externally powered typical from the reader) RFID Transponders. RFID READER A reader (now more typically referred to as an RFID interrogator) is basically a radio frequency (RF) transmitter and receiver, controlled by a microprocess or or digital signal processor.The reader, using an attached antenna, captures data from tags, then passes the data to a computer for processing. The reader decodes the data encoded in the tag(s) integrated circuit (silicon chip) and the data is passed to the host computer for processing. WORKING OF RFID Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that â€Å"wakes up† the tag and provides the power for the tag to respond to the reader.Data collected from tags is then passed through communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action. FREQUENCIES OF RFID RFID deployments tend to use unlicensed frequencies for their obvious cost benefits. There are four commonly used frequencies: †¢ Low frequency (LF) 125/134. 2 KHz. †¢ High frequency (HF) 13. 56 MHz. †¢ Ultra high frequency (UHF) (including 869 and 915 MHz). Microwave (at 2450 MHz, a band familiar to ISPs). A tag's read range performance is usually considered the primary gauge of its suitability for a particular application. It is important to remember that not all applications require maximum range. Tags in the LF-HF band have a range of 1 to 18 inches, while passive UHF tags can reach up to 20 feet, and microwave tags can reach 1 to 6 feet. The ranges greatly depend upon the surface on which the tag is mounted. BLOCK DIAGRAM BIOMETRIC SYSTEM In today’s world, the need for effective security is evident.Without effective security, many everyday activities are compromised. Specific security concerns include: †¢Protecting computer systems, PDAs, mobile phones, Internet appliances and similar devices from unauthorized access or use †¢Protecting motor vehicles and other valuable items from unauthorize d access or use preventing theft and fraud in financial transactions, in particular electronic transactions, including credit card payments and payments via the Internet. †¢ Restricting access to workplaces, warehouses and secures areas, such as military installations, to authorized personnel. Screening access to public transportation, in particular air travel. †¢ Authenticating the identity of an individual in drivers’ licenses, health cards, ID cards, and similar administrative documents. A major factor in ensuring security is the unique identification of individuals, or the authentication that a person is who he or she claims to be. This must be done reliably, rapidly, non-intrusively and at reasonable cost. In the past, this has been done by methods such as security tokens (passports, badges, etc. ), secure knowledge (passwords PIN codes, signature, etc. or recognition by a guardian (doorkeeper). These traditional approaches are all limited with respect to the a bove criteria. A promising approach for the future is biometrics. Biometrics offers a convenient, reliable and low-cost means of identifying or authenticating individuals, and can be implemented in unsupervised and remote situations. Biometrics seeks to identify individuals uniquely by measuring certain physical and behavioural characteristics and extracting a sample (also called a sampled template or live template) from these measurements in a standard data format.This sample is compared with a template (also called an enrolled template or signature), based on the same characteristics, that has been established as the unique identity of that individual and stored in the security system. A close match between sample and template confirms the identity of the individual. Attention has been focused on a small number of physical characteristics that can identify individuals uniquely, notably voice, gait, face, iris and retina patterns, palm prints and fingerprints. (DNA is excluded from this list because DNA sampling is intrusive and slow. Work is proceeding to develop electronic recognition systems based on all of these. This article focuses on fingerprints as the most advanced, mature and well-developed option. Based on centuries of experience and extensive research, fingerprints are at present considered to be the most reliable biometric for uniquely identifying an individual. In spite of some recent legal challenges in the USA, they are still regarded as giving proof of identity beyond reasonable doubt in almost all cases. The majority of the biometric-based security systems in operation today are based on fingerprint recognition.Thumb Impression FINGERCHIP TECHNOLOGY Finger Chip IC for fingerprint image capture combines detection and data conversion circuitry in a single rectangular CMOS die. It captures the image of a fingerprint as the finger is swept vertically over the sensor window. It requires no external heat, light or radio source. FINGERCHIP SENSOR T he Finger Chip sensor comprises an array of 8 rows by 280 columns, giving 2240 temperature-sensitive pixels. An additional dummy column is used for calibration and frame identification. The pixel pitch of 50 _m by 50 _m provides a resolution of 500 dpi over an image zone of 0. mm by 14 mm. This is adequate to capture a frame of the central portion of a fingerprint at an acceptable image resolution. This resolution also complies with the Image Quality Specification (IQS) from the IAFIS (Integrated Automated Fingerprint Identification System) of the U. S. Federal Bureau of Investigation (FBI). The pixel clock is programmable at up to 2 MHz, giving an output of 1780 frames per second. This is more than adequate for a typical sweeping velocity. An image of the entire fingerprint is re-constructed from successive frames using software provided. Biometric sensor ZIGBEEZigBee is a low-cost, low-power, wireless mesh network standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications. Low power-usage allows longer life with smaller batteries. Mesh networking provides high reliability and more extensive range. The technology is intended to be simpler and less expensive than other WPANs such as Bluetooth. ZigBee chip vendors typically sell integrated radios and microcontrollers with between 60 KB and 256 KB flash memory. ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868 MHz in Europe, 915 MHz in the USA and Australia, and 2. GHz in most jurisdictions worldwide. Data transmission rates vary from 20 to 250 kilobits/second. The ZigBee network layer natively supports both star and tree typical networks, and generic mesh networks. Every network must have one coordinator device, tasked with its creation, the control of its parameters and basic maintenance. Within star networks, the coordinator must be the central node. Both trees and meshes allow the use of ZigBee routers to extend communicat ion at the network level. ZIGBEE STACK ZigBee builds upon the physical layer and medium access control defined in IEEE standard 802. 5. 4 (2003 version) for low-rate WPAN's. The specification goes on to complete the standard by adding four main components: network layer, application layer, ZigBee device objects (ZDO's) and manufacturer-defined application objects which allow for customization and favour total integration. Besides adding two high-level network layers to the underlying structure, the most significant improvement is the introduction of ZDO's. These are responsible for a number of tasks, which include keeping of device roles, management of requests to join a network, device discovery and security.ZigBee is not intended to support power line networking but to interface with it at least for smart metering and smart appliance purposes. Because ZigBee nodes can go from sleep to active mode in 30msec or less, the latency can be low and devices can be responsive, particularly compared to Bluetooth wake-up delays, which are typically around three seconds. Because ZigBee nodes can sleep most of the time, average power consumption can be low, resulting in long battery life.

WORKING OF GSM MODULE GSM hardware tests are run in order to check the hardware support. The system will call GSM modem and it will get activated. After activation the Modem will check for hardware support. If the hardware is missing or some other hardware problem there w ill be error, resulting in communication failure and the application will be terminated. If hardware responds then the serial port will be opened for communication and GSM hardware will allow transmission of SMS.The system will then connect and after connection establishment the system will be able to detect intrusion and will alert user about the breach and similarly the system will update status of appliances by receiving SMS from the pre-defined cell number. SMS will be silently ignored if cell number is unauthorized. The system uses GSM technology thus providing ubiquitous access to the system for security and automated appliance control. Therefore this paper proposes a system that allows user to be control and provide security on detection of intrusion via SMS using GSM technology.POWER SUPPLY Power supply is the basic unit that provides corresponding operating voltage to each circuit.

The heart of the utility is that RFID makes gathering information about physical objects easy. Information about RFID tagged objects can be read through physical barriers, and from a distance. Our project utilized these RFID tags to improve the security system of a building by introducing a system that could read the RFID tagged smart cards that are placed in proximity to an antenna.Our project comes with option of finger print system, GSM system and camera system attached with the main RFID system. This help in making the security full proof and reduce the possibility of breaches. RFID devices have three primary elements: a chip, an antenna, and a reader. A fourth important part of any RFID system is the database wher e information about tagged smart card is stored. For wireless data transmission and networking between sensor nodes, the project uses ZigBee modules. The modules require minimal power and provide reliable delivery of data between devices with efficient security measures.This project is implemented in real time system. INTRODUCTION The major problem faced by organizations in security breach is related with doors without proper security system on them for their protection. Our project is going to solve these problems by using RFID technology. For wireless data transmission between tag and sensor nodes, the project uses ZigBee modules. Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.So the RFID is a wireless identification. Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag. RFID Reader is an integrated or passive network which is used to interrogate information from RFID tag (contains antennas to enable them to receive and respond to radiofrequency queries from an RFID transceiver). The RFID Reader may consist of antenna, filters, modulator, demodulator, coupler and a micro processor. We try to enhance the security up to a very effective level so that there are minimum possibilities in the security breach.For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. The system also creates a log containing check-in and check-out of each user along with basic information of user. OBJECTIVE The aim of the project is to design a system that have a small coverage area and can be use for authentication or identification purposes. â€Å"Security System Using RFID† is a system that uses RFID technology to maintain the security of the different rooms in same structure which can be monitored on real-time bases using the Data base server (PC).This system prevents unauthorized entry in rooms. For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. This ensures the reliability of the system and makes it difficult to breach. SYSTEM ANALYSIS EXISTING SYSTEM In the existing system, Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that â€Å"wakes up† the tag and provides the power for the tag to respond to the reader.Data collected from tags is then passed through communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action. The drawback in this system is the lack of security option available for the user. One can easily use others RFID tag to gain access in the desired place without their prior knowledge. This breach cannot be easily accounted as there is no record other then the RFID tag used which can mislead to undesirable situation.PROPOSED SYSTEM This system is of new kind in which finger print recognition system along with GSM and camera is newly added. In this system RFID along with ZigBee, microcontroller, biometric system, GSM, amplifier circuit, power supply, camera and database server (PC) is used. Different circuits work together to form an unreachable system so that the security can be enhanced to the maximum level possible. When RFID tag is sensed by the RFID receiver and finger print impression is given, the camera is activated which clicks the image of the user trying to access the system.This information is stored in the database along with time and date when the system was accessed and the GSM technology used in the system make sure that the concerned authority is notified about the activation of the sy stem along with result.

Visual Basic is relatively easy to learn and use. Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects.Scripting languages such as VBA and VBScript are syntactic ally similar to Visual Basic, but perform differently. A programmer can put together an application using the components provided with Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations. Visual basic is used to provide a simple interface about the program between user and system software. This is also used for storing the data and act as database for the system.MIKRO BASIC MikroBasic is a powerful, feature rich development tool for PIC microcontrollers. It is designed to provide the customer with the easiest possible solution for developing applications for embedded systems, without compromising performance or control. Highly advanced IDE, broad set of hardware libraries, comprehensive documentation, and plenty of ready to run example programs should be more than enough to get you started in programming microcontrollers. FEATURESMikroBasic allows you to quickly develop and deploy complex applicatio ns: †¢Write your BASIC source code using the built-in Code Editor (Code and Parameter Assistants, Syntax Highlighting, Auto Correct, Code Templates, and more†¦) †¢Use the included mikroBasic libraries to dramatically speed up the development: data acquisition, memory, displays, conversions, communications†¦ Practically all P12, P16, and P18 chips are supported. †¢Monitor your program structure, variables, and functions in the Code Explorer. †¢Generate commented, human-readable assembly, and standard HEX compatible with all programmers. Inspect program flow and debug executable logic with the integrated Debugger. †¢Get detailed reports and graphs: RAM and ROM map, code statistics, assembly listing, calling tree, and more†¦ †¢We have provided plenty of examples for you to expand, develop, and use as building bricks in your projects. Copy them entirely if you deem fit – that’s why we included them with the compiler. HARDWARE DE SCRIPTION RFID TAGS Tags also sometimes are called â€Å"transponders†. RFID tags can come in many forms and sizes. Some can be as small as a grain of rice.Data is stored in the IC and transmitted through the antenna to a reader. The two commonly used RFID Transponders [2] are Active (that do contain an internal battery power source that powers the tags chip) and passive (that does not have an internal power source, but are externally powered typical from the reader) RFID Transponders. RFID READER A reader (now more typically referred to as an RFID interrogator) is basically a radio frequency (RF) transmitter and receiver, controlled by a microprocessor or digital signal processor.The reader, using an attached antenna, captures data from tags, then passes the data to a computer for processing. The reader decodes the data encoded in the tag(s) integrated circuit (silicon chip) and the data is passed to the host computer for processing. WORKING OF RFID Information is sent to an d read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that â€Å"wakes up† the tag and provides the power for the tag to respond to the reader.Data collected from tags is then passed through communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action. FREQUENCIES OF RFID RFID deployments tend to use unlicensed frequencies for their obvious cost benefits. There are four commonly used frequencies: †¢ Low frequency (LF) 125/134. 2 KHz. †¢ High frequency (HF) 13. 56 MHz. †¢ Ultra high frequency (UHF) (including 869 and 915 MHz). †¢ Microwave (at 2450 MHz, a band familiar to ISPs).A tag's read range performance is usually considered the primary gauge of its suitability for a particular application. It is important to remember t hat not all applications require maximum range. Tags in the LF-HF band have a range of 1 to 18 inches, while passive UHF tags can reach up to 20 feet, and microwave tags can reach 1 to 6 feet. The ranges greatly depend upon the surface on which the tag is mounted. BLOCK DIAGRAM BIOMETRIC SYSTEM In today’s world, the need for effective security is evident. Without effective security, many everyday activities are compromised.Specific security concerns include: †¢Protecting computer systems, PDAs, mobile phones, Internet appliances and similar devices from unauthorized access or use †¢Protecting motor vehicles and other valuable items from unauthorized access or use preventing theft and fraud in financial transactions, in particular electronic transactions, including credit card payments and payments via the Internet. †¢ Restricting access to workplaces, warehouses and secures areas, such as military installations, to authorized personnel. †¢ Screening access to public transportation, in particular air travel. Authenticating the identity of an individual in drivers’ licenses, health cards, ID cards, and similar administrative documents. A major factor in ensuring security is the unique identification of individuals, or the authentication that a person is who he or she claims to be. This must be done reliably, rapidly, non-intrusively and at reasonable cost. In the past, this has been done by methods such as security tokens (passports, badges, etc. ), secure knowledge (passwords PIN codes, signature, etc. ) or recognition by a guardian (doorkeeper). These traditional approaches are all limited with respect to the above criteria.A promising approach for the future is biometrics. Biometrics offers a convenient, reliable and low-cost means of identifying or authenticating individuals, and can be implemented in unsupervised and remote situations. Biometrics seeks to identify individuals uniquely by measuring certain physical and behav ioural characteristics and extracting a sample (also called a sampled template or live template) from these measurements in a standard data format. This sample is compared with a template (also called an enrolled template or signature), based on the same characteristics, that has been established as he unique identity of that individual and stored in the security system. A close match between sample and template confirms the identity of the individual. Attention has been focused on a small number of physical characteristics that can identify individuals uniquely, notably voice, gait, face, iris and retina patterns, palm prints and fingerprints. (DNA is excluded from this list because DNA sampling is intrusive and slow. ) Work is proceeding to develop electronic recognition systems based on all of these. This article focuses on fingerprints as the most advanced, mature and well-developed option.Based on centuries of experience and extensive research, fingerprints are at present consi dered to be the most reliable biometric for uniquely identifying an individual. In spite of some recent legal challenges in the USA, they are still regarded as giving proof of identity beyond reasonable doubt in almost all cases. The majority of the biometric-based security systems in operation today are based on fingerprint recognition. Thumb Impression FINGERCHIP TECHNOLOGY Finger Chip IC for fingerprint image capture combines detection and data conversion circuitry in a single rectangular CMOS die.It captures the image of a fingerprint as the finger is swept vertically over the sensor window. It requires no external heat, light or radio source. FINGERCHIP SENSOR The Finger Chip sensor comprises an array of 8 rows by 280 columns, giving 2240 temperature-sensitive pixels. An additional dummy column is used for calibration and frame identification. The pixel pitch of 50 _m by 50 _m provides a resolution of 500 dpi over an image zone of 0. 4 mm by 14 mm. This is adequate to capture a frame of the central portion of a fingerprint at an acceptable image resolution.This resolution also complies with the Image Quality Specification (IQS) from the IAFIS (Integrated Automated Fingerprint Identification System) of the U. S. Federal Bureau of Investigation (FBI). The pixel clock is programmable at up to 2 MHz, giving an output of 1780 frames per second. This is more than adequate for a typical sweeping velocity. An image of the entire fingerprint is re-constructed from successive frames using software provided. Biometric sensor ZIGBEE ZigBee is a low-cost, low-power, wireless mesh network standard.The low cost allows the technology to be widely deployed in wireless control and monitoring applications. Low power-usage allows longer life with smaller batteries. Mesh networking provides high reliability and more extensive range. The technology is intended to be simpler and less expensive than other WPANs such as Bluetooth. ZigBee chip vendors typically sell integrated rad ios and microcontrollers with between 60 KB and 256 KB flash memory. ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868 MHz in Europe, 915 MHz in the USA and Australia, and 2. GHz in most jurisdictions worldwide. Data transmission rates vary from 20 to 250 kilobits/second. The ZigBee network layer natively supports both star and tree typical networks, and generic mesh networks. Every network must have one coordinator device, tasked with its creation, the control of its parameters and basic maintenance. Within star networks, the coordinator must be the central node. Both trees and meshes allow the use of ZigBee routers to extend communication at the network level. ZIGBEE STACK ZigBee builds upon the physical layer and medium access control defined in IEEE standard 802. 5. 4 (2003 version) for low-rate WPAN's. The specification goes on to complete the standard by adding four main components: network layer, application layer, ZigBee device objects (ZDO's) and manufacturer-defined application objects which allow for customization and favour total integration. Besides adding two high-level network layers to the underlying structure, the most significant improvement is the introduction of ZDO's. These are responsible for a number of tasks, which include keeping of device roles, management of requests to join a network, device discovery and security.ZigBee is not intended to support power line networking but to interface with it at least for smart metering and smart appliance purposes. Because ZigBee nodes can go from sleep to active mode in 30msec or less, the latency can be low and devices can be responsive, particularly compared to Bluetooth wake-up delays, which are typically around three seconds. Because ZigBee nodes can sleep most of the time, average power consumption can be low, resulting in long battery life.

For wireless data transmission and networking between sensor nodes, the project uses ZigBee modules. The modules require minimal power and provide reliable delivery of data between devices with efficient security measures.This project is implemented in real time system. I NTRODUCTION The major problem faced by organizations in security breach is related with doors without proper security system on them for their protection. Our project is going to solve these problems by using RFID technology. For wireless data transmission between tag and sensor nodes, the project uses ZigBee modules. Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.So the RFID is a wireless identification. Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag. RFID Reader is an integrated or passive network which is used to interrogate information from RFID tag (contains antennas to enable them to receive and respond to radiofrequency queries from an RFID transceiver). The RFID Reader may consist of antenna, filters, modulator, demodulator, coupler and a micro processor. We try to enhance the security up to a very effective level so tha t there are minimum possibilities in the security breach.For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. The system also creates a log containing check-in and check-out of each user along with basic information of user. OBJECTIVE The aim of the project is to design a system that have a small coverage area and can be use for authentication or identification purposes. â€Å"Security System Using RFID† is a system that uses RFID technology to maintain the security of the different rooms in same structure which can be monitored on real-time bases using the Database server (PC).This system prevents unauthorized entry in rooms. For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. This ensures the reliability of the system and makes it difficult to breach. SYSTEM ANALYSIS EXISTIN G SYSTEM In the existing system, Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that â€Å"wakes up† the tag and provides the power for the tag to respond to the reader.Data collected from tags is then passed through communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action. The drawback in this system is the lack of security option available for the user. One can easily use others RFID tag to gain access in the desired place without their prior knowledge. This breach cannot be easily accounted as there is no record other then the RFID tag used which can mislead to undesirable situation.PROPOSED SYSTEM This system is of new kind in which finger print recognition system along with GSM and camera is newly added . In this system RFID along with ZigBee, microcontroller, biometric system, GSM, amplifier circuit, power supply, camera and database server (PC) is used. Different circuits work together to form an unreachable system so that the security can be enhanced to the maximum level possible. When RFID tag is sensed by the RFID receiver and finger print impression is given, the camera is activated which clicks the image of the user trying to access the system.This information is stored in the database along with time and date when the system was accessed and the GSM technology used in the system make sure that the concerned authority is notified about the activation of the system along with result.

Visual Basic is relatively easy to learn and use. Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects.Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but perform differently. A programmer can put together an application using the components provided with Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations. Visual basic is used to provide a simple interfa ce about the program between user and system software. This is also used for storing the data and act as database for the system.MIKRO BASIC MikroBasic is a powerful, feature rich development tool for PIC m

An Overview of Burlesque Literature With Examples

An Overview of Burlesque Literature With Examples Burlesque literature is a form of satire. It is often and perhaps best described as â€Å"an incongruous imitation.†Ã‚   The purpose of burlesque literature is to imitate the manner or the subject matter of a â€Å"serious† literary genre, author, or work through a comic inversion.   Imitations of manner might include the form or the style, whereas imitation of matter is meant to satirize the subject being explored in a particular work or genre.    Elements of Burlesque While a burlesque piece may aim to poke fun at a particular work, genre, or subject, it is most often the case that burlesque will be a satire of all of these elements. What is important to consider about this mode of literature is that the point of the burlesque is to create an incongruity, a ridiculous disparity, between the manner of the work and the matter of it. While â€Å"travesty,† â€Å"parody,† and â€Å"burlesque† are terms that are often used interchangeably, it is perhaps better to consider travesty and parody as types of burlesque, with burlesque being the generic term for the larger mode. That being said, it is also important to note that a burlesque piece may employ a number of techniques which fall into the larger category; it is not necessarily the case that all burlesque literature will share all of the same features. High And Low Burlesque There are two primary types of burlesque, the â€Å"High Burlesque† and the â€Å"Low Burlesque.†Ã‚   Within each of these types, there are further divisions. These sub-divisions are based on whether the burlesque satirizes a genre or literary type, or, instead, a specific work or author. Let’s take a closer look at these types. High Burlesque occurs when the form and style of the piece are dignified and â€Å"high,† or â€Å"serious† while the subject matter is trivial or â€Å"low.†Ã‚   The types of high burlesque include the â€Å"mock epic† or â€Å"mock-heroic† poem, as well as the parody. A mock epic is itself a type of parody.   It imitates the generally complicated and elaborate form of the epic poem, and it also imitates that genre’s rather formalized style. In so doing, however, it applies this â€Å"high† form and style to rather ordinary or insignificant topics. A significant example of a mock epic is Alexander Pope’s The Rape of the Lock (1714), which is elegant and elaborate in style, but which, on its surface, has only a lady’s curl as its subject. A parody, similarly, will imitate one or many of a variety of characteristics of a piece of high, or serious, literature.   It might mock the style of a certain author or the features of an entire literary genre. Its focus might also be an individual work.   The point is to employ those same features and characteristics, at a high or serious level, and exaggerate it while simultaneously employing a low, comic, or otherwise inappropriate subject. Parody has been the most popular form of burlesque since the early 1800s.   Some of the best examples include Jane Austen’s Northanger Abbey (1818) and A.S. Byatt’s Possession: A Romance (1990).   Parody predates these, however, appearing in such works as Joseph Andrews (1742) by Henry Fielding, and â€Å"The Splendid Shilling† (1705) by John Phillips. Low Burlesque occurs when the style and manner of a work are low or undignified but, in contrast, the subject matter is distinguished or high in status. The types of low burlesque include the Travesty and the Hudibrastic poem. A travesty will mock a â€Å"lofty† or serious work by treating the high subject in a grotesque and undignified manner and (or) style.   One classic example of a modern travesty is the film Young Frankenstein, which mocks   Mary Shelley’s original novel, (1818). The Hudibrastic poem is so-named for Samuel Butler’s Hubidras (1663).   Butler turns the  chivalric romance on its head, inverting the dignified style of that genre in order to present a hero whose travels were mundane and often humiliating. The Hudibrastic poem might also employ colloquialisms and other examples low style, such as the doggerel verse, in place of traditionally high style elements. The Lampoon In addition to High and Low Burlesque, which include parody and travesty, another example of the burlesque is the lampoon.   Some short, satirical works are considered lampoons, but one might also find the lampoon as a passage or insert into a longer work.   Its goal is to make ridiculous, often via caricature, a particular person, usually by describing the nature and appearance of the individual in an absurd way. Other Notable Burlesque Works The Comedies of AristophanesTale of Sir Thopas (1387) by Geoffrey Chaucer Morgante (1483) by Luigi Pulci The Virgile Travesty (1648-53) by Paul Scarron The Rehearsal (1671) by George Villier Beggars Opera (1728) by John Gay Chrononhotonthologos (1734) by Henry Carey

how rap effects socity essays

how rap effects socity essays Many individuals in our society today believe that the positive portrayal of violence and sex in rap music has negative effects on its listeners. Due to this widespread perception, many studies have systematically examined rap music for evidence of its negative effects. This issue is important in that rap music has become a universal form of art. Rap music has spread into the suburbs where affluent white youth are among its greatest supporters. It is important to document the extent to which the positive portrayal of violence and sex in rap music effects its listeners, since such music may have a negative impact on today's youth. Violent crime increased by over 500 percent during the three decades ending in 1990. There may be a host of factors contributing to this social pathology, but "violence in the media" is certainly one of them. "Music industry insiders often shirk responsibility by saying their music reflects society but does not impact it," Waliszewski observes. "Some music industry insiders . . . have argued that, as performers and 'actors on the stage,' musicians cannot be held responsible for their fans' criminal behavior. Their anti-social messages are not to be taken seriously because . . . they don't actually mean what they say." Such claims are disingenuous at best. Whether they know what they're doing or not, the purveyors of this musical madness should be held accountable for the damage they've done to an entire generation of young ...

Reading strategy Term Paper Example | Topics and Well Written Essays - 1000 words

Reading strategy - Term Paper Example A learner needs to survey the book or the article before reading it. A learner need to carry a quick over view of the article in an attempt to get the general overview and idea the author intends to communicate (Van Blerkom, 2009). This will help the reader to have some knowledge on all what the article or the book is all about even before embarking on serious reading of the article. Second step applied in this system of reading is the formulation of a question. A learner needs to formulate a key question he or she will be addressing before he engages herself in reading the article or section. For example, a heading like â€Å"sensory adaptation† can be changed to a question like â€Å"what is sensory adaptation†. Formulating questions force a reader to think about what they are reading about (Allen, 2008). It makes a reader to try to predict what the author main point will be. This gives the reader an ample time during the entire reading process as he or she is in a position to easily note down the key point from the article or the book she is reading. The learner after formulating the question, then he or she need to carefully go through the content of the article. This will help him, or her to get the crucial information that will help her in answering the question he or she had formulated in the second stage (Van Blerkom, 2009). As the learner tries to read the article in search of answers to the questions he had formulated before, he or she become actively involved in the text material. After going through the article, the learners need to recite the answer to the question they had formulated at the early stage. The learners need to record the answers using their different words. The learner should not necessarily look at the text they are reading as they recite the answers. If the learner finds it difficult to recall part or all the answers, then they need to glance over the section they were reading again (Allen,
