| RFID – BASED INTELLIGENT BOOKS SHELVING SYSTEM. ABSTRACT: Searching and sorting misplaced books is a difficult task often carried out by the library personnel, librarians are busy with searching misplaced books, which are left in wrong locations. By library users it is quite difficult and almost impractical to place back all books to their assigned locations daily. To overcome this, radio frequency identification based intelligent shelving system has been proposed in which each book its own has assigned location in order to get easy assessment. It also provides significant improvement on book identification, tracking the objects and stock control. IMPLEMENTATION: Each book is equipped with an ARFID. The data warehouse has pre=stored location data with PC software display. The reader is installed on a X-Y moving mechanism which track as per commend from the base unit.. This mechanism has stepper motor drive and all related accessories. The mechanism platform is installed with a RFID reader, radio data receiver, processor, drive unit, and battery. The base reader unit has main processor, data warehouse, central command, interface unit, and a PC with software. | |

| Gen2-Based RFID Authentication Protocol for Security and Privacy Abstract EPCglobal Class-1 Generation-2 specification (Gen2 in brief) has been approved as ISO18000-6C for global use but the identity of tag (TID) is transmitted in plaintext which makes the tag traceable and clonable. Several solutions have been proposed based on traditional encryption methods, such as symmetric or asymmetric ciphers, but they are not suitable for low-cost RFID tags. Recently, some lightweight authentication protocols conforming to Gen2 have been proposed. However, the message flow of these protocols is different from Gen2. Existing readers may fail to read new tags. In this paper, we propose a novel authentication protocol based on Gen2, called Gen2^ {+}, for low-cost RFID tags. Our protocol follows every message flow in Gen2 to provide backward compatibility. Gen2^ {+} is a multiple round protocol using shared pseudonyms and Cyclic Redundancy Check (CRC) to achieve reader-to-tag authentication. Conversely, Gen2^ {+} uses the memory read command defined in Gen2 to achieve tag-to-reader authentication. We show that Gen2^ {+} is more secure under tracing and cloning attacks. | |
| PC Based data acquisition system by stimulating SPI and I2C protocol - computer science crazy | protocol, stimulating, system, acquisition, data, Based, |
| PC Based data acquisition system by stimulating SPI and I2C protocol Many times it is required to monitor physical phenomena such as temperature, pressure humidity, light intensity, sound intensity, force, etc. Such physical phenomena can be monitored by digital systems employing sensors. However sensor generally produces a change in the resistance, voltage or current. All such phenomena can be converted in to a change in voltage levels. Since the sensors and the subsequent signal conditioning circuits provide a proportionate change in voltage with respective the phenomena, this cannot be directly interpreted by a digital system. A sensor is ussaually an analog voltage and can take any value between +10 to -10 volts. However a digital system has only two states (ON) or (OFF). Thus it is required to have additional circuitry between the digital systems and analog systems that translate the analog signals in to a digital signals. Such conversion can be perform by an analog to digital converter. The Serial Peripheral interface Bus or SPI (often pronounced “spy”) bus Is a synchronous serial data link standard that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. The I2C bus physically consists of two active wires and a ground connection. The active wires called SDA and SCL, are both bi-directional. SDA is a serial data line, SCL is a serial clock line. Data Acquisition refers to reading the data continuously from any sensor. Here we are continuously monitoring the data through PC. We are concentrating mostly on serial communication. The data which we are receiving from the sensor is received by the micro controller using ADC. We need to monitor this data on the PC and on the LCD, In order to send the data we are using serial communication. We get the information like Date and Time with our data. The buzzer rings when the temperature reaches a critical temperature of 35degrees centigrade. The data that is stored in PC is easier to monitor are retrieve at any time compared to storing in a particular memory. Now a days we are using the same process as storing the data in the PC in any kind of industr | |

Most of the home appliances are connected to AC mains so, a special care is to be taken to switch the appliances | |
| LCD BASED SECURITY SYSTEM - computer science crazy | SYSTEM, SECURITY, BASED, |
| LCD BASED SECURITY SYSTEM Security is one of the most important concerns for everybody. Everybody wants to secure their home, offices, industry from unauthorized persons. To make this task an easy, this is one of the cheap and best system. This project consists of LCD which shows that whether the person entered is authorized or not. The user, who wants to enter into the room or office, has to enter a pin or password through keypad and if the entered password is correct the door will open. The verification of password is done by using microcontroller which stores all authorized passwords and accordingly instructs the other peripherals i.e. door (using stepper motor) to open. If the password entered is wrong a beep or a buzzer will be ON and LED will glow. As well as the persons details such as name, id can be shown on display i.e. LCD. The components uses in this project are AT89S52 Micro controller, LCD and a normal telephone keypad. The system is fully controlled by the 8 bit microcontroller AT89s52. The password is stored in memory of that we can change it at anytime. The software which is used as a backenend is Embedded C “KIEL uvision” | |
| Co-operative cache based data access in ad hoc networks - computer science crazy | networks, access, data, based, cache, Co operative, |
| Co-operative cache based data access in ad hoc networks Wireless ad hoc network is a collection of autonomous nodes or terminals that communicate with each other by forming a multihop radio network and maintaining connectivity in a decentralized manner. Since the nodes communicate over wireless links, they have to contend with the effects of radio communication, such as noise, fading, and interference. In addition, the links typically have less bandwidth than in a wired network. Each node in a wireless ad hoc network functions as both a host and a router, and the control of the network is distributed among the nodes. The network topology is in general dynamic, because the connectivity among the nodes may vary with time due to node departures, new node arrivals, and the possibility of having mobile nodes. Hence, there is a need for efficient routing protocols to allow the nodes to communicate over multihop paths consisting of possibly several links in a way that does not use any more of the network resources than necessary. TYPES OF AD HOC NETWORKS There are two major types of wireless ad hoc networks: a) Mobile Ad hoc Networks b) Smart Sensor Networks Mobile Ad Hoc Networks (MANETs) In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication for emergency or rescue operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of Mobile Ad Hoc Networks. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves, i.e., routing functionality will be incorporated into mobile nodes. Cellular Network vs. Ad Hoc Network The set of applications for MANETs is diverse, ranging from small, static networks that are constrained by power sources, to large-scale, mobile, highly dynamic networks. The design of network protocols for these networks is a complex issue. Regardless of the application, MANETs need efficient distributed algorithms to determine network organization, link scheduling, and routing. However, determining viable routing paths and delivering messages in a decentralized environment where network topology fluctuates is not a well defined problem. While the shortest path (based on a given cost function) from a source to a destination in a static network is usually the optimal route, this idea is not easily extended to MANETs. Factors such as variable wireless link quality, propagation path loss, fading, multiuser interference, power expended, and topological changes, become relevant issues. The network should be able to adaptively alter the routing paths to alleviate any of these effects. Moreover, in a military environment, preservation of security, latency, reliability, intentional jamming, and recovery from failure are significant concerns. Military networks are designed to maintain a low probability of intercept and/or a low probability of detection. Hence, nodes prefer to radiate as little power as necessary and transmit as infrequently as possible, thus decreasing the probability of detection or interception. A lapse in any of these requirements may degrade the performance and dependability of the network. | |
| Adaptive Optics in Ground Based Telescopes - computer science crazy | Telescopes, Based, Ground, Optics, Adaptive, |
| WHAT IS ADAPTIVE OPTICS ? Adaptive optics refers to optical systems which adapt to compensate for optical effects introduced by the medium between the object and its image. In theory a telescope's resolving power is directly proportional to the diameter of its primary light gathering lens or mirror. But in practice , images from large telescopes are blurred to a resolution no better than would be seen through a 20 cm aperture with no atmospheric blurring. At scientifically important infrared wavelengths, atmospheric turbulence degrades resolution by at least a factor of 10. Space telescopes avoid problems with the atmosphere, but they are enormously expensive and the limit on aperture size of telescopes is quite restrictive. The Hubble Space telescope, the world's largest telescope in orbit , has an aperture of only 2.4 metres, while terrestrial telescopes can have a diameter four times that size. In order to avoid atmospheric aberration, one can turn to larger telescopes on the ground, which have been equipped with ADAPTIVE OPTICS system. With this setup, the image quality that can be recovered is close to that the telescope would deliver if it were in space. Images obtained from the adaptive optics system on the 6.5 m diameter telescope, called the MMT telescope illustrate the impact | |
| Examination of a GIS-Based Water Quality Model using USGS Gaged Watersheds in Marylan - mechanical wiki | Marylan, Watersheds, Gaged, USGS, using, Model, Quality, Water, GIS Based, Examination, |
| Water quality models are important tools used by the Maryland Department of the Environment (MDE) in
developing Total Maximum Daily Loads (TMDLs), which serve as water quality standards. The MDE tool,
which spatially interpolates output from the Chesapeake Bay Program Watershed Model (WSM), is often
used because it requires little time, data, or training. In contrast, the WSM requires extensive
time, data, and training to run. This study examines if the MDE tool provides accurate estimates of
pollutant loads and whether the mid-level complexity model AVGWLF. http://www.lib.umd.edu/drum/bitstream/1903/7024/1/umi-umd-4577.pdf | |

| DESIGN OF AN RFID – BASED MANUFACTURING MONITORING AND ANALYSIS SYSTEM ABSTRACT. Radio Frequency identification technology has become an important driver in the modern production logistics activities of today’s information-based industries and economics. With the modern development and latest technology, companies focus more on how these technologies can be implemented and promoted in order to improve their value-added process. In this project presents one such practical implementation approach for the monitoring and analysis of a discrete manufacturing environment using the super RFID technology. Monitoring the parts flows in manufacturing system time-wise and location-wise is very critical for productivity, cost, quality, inventory, and speed. In companies when the production automation has been implemented the parts are monitored by the system. This may allow better monitoring of the manufacturing process with expedient material flow and more effective planning and control. This super RFID based manufacturing monitoring and analysis system to monitor where and when a part is located throughout its flow in a production process using RFID tag placed on the parts and antennas located at appropriate places. The system will enable the visibility of multiple parts simultaneously without requiring operator support and collect the following information related to a part. 1. Arrival time to a workstation. 2. Activity starts time. 3. Activity end time. 4. Departure time from the workstation. 5. Location of a part. Implementation In this system every parts in the production is equipped with a super RFID tag. The manufacturing plant is installed with reader antenna at appropriate locations. The data from the part/tag is read on real time. The reader can receive data from many tags at a time. The location information and other data is processed in the base reader unit and feed in to a PC. The final display is shown in the PC using software. Hardware involved. : Super compact active RFID tag (as per monitoring parts required) Directional antenna, Reader base unit, Interface adaptor, PC software. | |
| A microprocessor-based generator of synchronizing signal and test signal for colour T - Electrical Fan | A microprocessor based generator of synchronizing signal and test signal for colour TV, colour, signal, test, signal, synchronizing, generator, microprocessor based, |
| Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, blanking signal and a series of test signals are originally realized by a number of sequential circuits and logical gates. Now, this test signal generator has smaller size, higher stability and lower cost compared with former ones which consist of more hardware. All of the programs are stored in EPROM. We can change the test patterns and their orders easily by changing the programs without changing the main structure of the system. On the other hand, varied kinds of non-standard TV sync signals and test patterns can also be obtained in this way. | |
