Abstract: The electric power industry is currently undergoing an unprecedented reform, ascribable to, one of the most exciting and potentially profitable recent developments in increasing usage of artificial intelligence techniques. The artificial neural network approach has attracted number of applications especially in the field of power system since it is a model free estimator. Neural networks provide solutions to very complex and nonlinear problems. Nonlinear problems, like load forecasting that cannot be solved with standard algorithms but can be solved with a neural network with remarkable accuracy. Modern interconnected power systems often consist of thousands of pieces of equipment each of which may have an effect on the security of the system. Neural networks have shown great promise for their ability to quickly and accurately predict the system security when trained with data collected from a small subset of system variables.

The intention of this paper is to give an overview of application of artificial intelligence and neural network (NN) techniques in power systems to prognosticate load on power plant and contingency in case of any unexpected outage. In this paper we present the key concepts of artificial neural networks, its history, imitation of brain neuron’s architecture and finally the applications (load forecasting and contingency analysis). The applications of artificial intelligence in areas of load forecasting by error Backpropagation learning algorithm and contingency analysis based on Quality index have been perspicuously explained

Abstract:

The automated use of physiological or behavioral characteristics to determine or verify identity. To elaborate on this definition, physiological biometrics are based on measurements and data derived from direct measurement of a part of the human body. Fingerprint, iris-scan, retina-scan, hand geometry, and facial recognition are leading physiological biometrics. Biometric system is the integrated biometric hardware and software used to conduct biometric identification or verification. A generalized biometric system is expressed nearly with figure.

Various biometric technologies are fingerprint identification, speaker recognition, facial recognition, hand geometry, signature-scan, keystroke-scan, palm-scan, etc. Among these popular recognition techniques like fingerprint recognition , facial recognition and speech recognition are clearly explained. An automatic personal identification system based solely on one methodology often cannot meet the system performance requirements. So a combination of two or more methodologies is used to achieve required performance, which is called multibiometrics. In this paper we explained an example of multibiometric system, which combines fingerprint identification, speech recognition and facial recognition. A neatly sketched figure is used to describe the process in brief.

Biometrics has wide area applications; Most of them are covered in this paper.
Also some of the future applications like ATM machine, workstation and network access, travel and tourism and telephone transactions are given.

Abstract: This paper provides an introduction to biometric security; Biometrics has been the emerging technology during the past decade. The technology appears to be the answer to the growing concern of the safety and security in both personal and public environments. Taking into consideration the tragic events of 11/9/2001, biometrics has received a great deal of attention and recognition. As the focus on security continues to intensify, individuals, companies, and organizations are quickly trying to learn more about the “what’s” and “how’s” of biometrics.

In our paper we will describe what biometrics technology is, how the technology is utilized and the different methods that are used. We will briefly describe four existing biometric technologies: facial recognition, finger print recognition, and iris recognition and palm geometry. Each of these technologies is unique in their own way, but they all attempt to provide the same safe guards to an individual, an object(s), a room or a building. These technologies may prove to be advantageous by eliminating security threats while optimizing the convenience to today’s organizations.

Abstract: With the advent of the Internet and the plurality and variety of fancy applications it brought with it, the demand for more advanced services on cellular phones is increasingly becoming urgent. Unfortunately, so far the introduction of new enabling technologies did not succeed in boosting new services. The adoption of Internet services has shown to be more difficult due to the difference between the Internet and the mobile telecommunication system. The goal of this paper is to examine the characteristics of the mobile system and to clarify the constraints that are imposed on existing mobile services. The paper will also investigate successively the enabling technologies and the improvements they brought. Most importantly, the paper will identify their limitations and capture the fundamental requirements for future mobile service architectures namely openness, separation of service logic and content, multi-domain services, personalization, Personal Area Network (PAN)-based services and collaborative services. The paper also explains the analysis of current mobile service architecture such as voice communication, supplementary services with intelligent network, enabling services on SIM with SIM application tool kit, text services with short message service, internet services with WAP and dynamic applications on mobile phones with J2ME.

Further our paper gives information on challenges of mobile computing which includes harsh communications, connections, bandwidth and heterogeneous networks. Under research issues seamless connectivity over multiple overlays,scalable mobile processing ,wireless communications,mobility and portability are discussed.

Abstract: This paper deals with the development of an ultra dense data storage concept code named “MILLIPEDE”, developed by IBM, based on the model of an Atomic Force Microscope (AFM) which can be seen as the Nanotech equivalent of the primitive punch card technology. With this new technique, nanometer-sized bit indentations (30-40nm) and similar pitch sizes have been made by high resonant frequency cantilevers/tips on a very thin polymethylmethacrylate layer (PMMA), which is typically 40-50nm thick by heating the tips to high temperature (450°C), resulting in data storage densities of up to 1 Tb/in2. High data rates are achieved by massive parallel operation of large two-dimensional (2-D) atomic force microscope (AFM) arrays that have been batch-fabricated by silicon surface-micromachining techniques. A detailed discussion on potential of the data storage in the novel technique has been discussed with respect to the data write, read and erase techniques using time multiplexed electronics and thermal sensing. The all-crucial nanoscale fabrication considerations of Millipede are also being highlighted.

Abstract: Grid computing, emerging as a new paradigm for next-generation computing, enables the sharing, selection, and aggregation of geographically distributed heterogeneous resources for solving large-scale problems in science, engineering, and commerce. The resources in the Grid are heterogeneous and geographically distributed. Availability, usage and cost policies vary depending on the particular user, time, priorities and goals. It enables the regulation of supply and demand for resources.

It provides an incentive for resource owners to participate in the Grid; and motivates the users to trade-off between deadline, budget, and the required level of quality of service. The thesis demonstrates the capability of economic-based systems for wide-area parallel and distributed computing by developing users’ quality-of-service requirements-based scheduling strategies, algorithms, and systems. It demonstrates their effectiveness by performing scheduling experiments on the World-Wide Grid for solving parameter sweep—task and data parallel—applications.

This paper focuses on introduction, grid definition and its evolution. It covers about grid characteristics, types of grids and an example describing a community grid model. It gives an overview of grid tools, various components, advantages followed by conclusion and bibliography.

Abstract: “Human – Computer Interaction (HCI)” is the study of interaction between people (users) and computers. It is an interdisciplinary subject, relating computer science with many other fields of study and research. Interaction between users and computers occurs at the user interface which includes both hardware i.e. peripherals and other hardware and software for example determining which, and how, information is presented to the user on a screen.

In this paper we describe a physical user interface system for easy and natural user-computer interaction. VisulaPen is vision-based system for real-time detection and tracking of a stylus that completely replaces mouse and keyboard, thus providing a valid input device for mobile computers, and its low computational complexity renders it suitable also for PDAs. The system can be operated from a wide range of distances (either from a desk or from a wall – mounted projection panel) and is able to work with all lightning conditions. The architecture of the system is here described, and experimental results in several tests are presented and commented.

Abstract: Contamination of drinking water due to arsenic is a severe problem with regards to health hazards. Most of the techniques developed are for pentavalent arsenate species and are not very effective for trivalent arsenite, which is also found in many places and has toxicity higher than arsenate. In the present work an attempt to remove arsenite by using activated alumina was made. Effect of adsorbent dose, solution pH, and time has been investigated. The arsenite removal was strongly dependent on pH, contact time and adsorbent dose. The results show that the activated alumina can be very effective adsorbent for arsenite and arsenate..

Abstract: The science of nanotechnology, now a days is leaving trademark prospects for better living. The motto of nanotechnology is “ever smaller and ever faster”. In this territory or field it has also encroached its arms into reach and development of hydrogen fuel cells. Carbon nanotubes have been intensively investigated for their fundamental technical importance for hydrogen storage. New techniques being researched may soon make hydrogen storage more compact safe and efficient. This is accomplished by using various approaches to shape carbon into microscopic cylindrical structures known as nanotubes and nanofibers, molecular cousins of “buck minister fullerene” (C60) or “bucky balls”. One of the critical factors in nanotubes usefulness as a hydrogen storage medium is the ratio of stored hydrogen to carbon.

Developing high-density hydrogen system, about 5-wt% that can release hydrogen at a temperature lower than 1000C has been the focus and the goal of researchers. The basic current approaches of hydrogen storage a compressed gas, liquid or in the form of solid hydrogen. A solid hydrogen storage system is reliable, sample to engineer and tremendously safer. Our objective has been to utilize the physisorption effect and generate chemisorption effect by introducing transition metals and hydrogen-bonding clusters is expected to allow us to tune the material for hydrogen sorption at desired temperature and pressures.

Carbon nanotechnology represents a new direction for solid hydrogen storage. Especially, if these materials can be altered to store large amounts of hydrogen at room temperature, samples have been doped and spectroscopic characterization was conducted. These impeded clusters are capable of bonding large amounts of hydrogen with favorable thermodynamic and enhanced kinetics, while the transition metals catalyze the hydrogen to react with clusters or nanotubes systems.

Abstract: The Human Resource decides the democracy of our country INDIA. Democracy is mainly enriched by general elections in our country. Our paper mainly aims at providing a guaranteed solution for the prevailing malpractices being involved in general elections. We come up with biometric solution against rigging, miscreant and hacking of personnel database. As many as 15 types of identifications schemes are used in general elections nowadays. So the rate of interchange is high. But, this can be avoided by our new trend of implementing “IRIS SCANNING MECHANISM”. Biometry can be the only way for offering greater security and convenience than traditional methods of personal recognition. As the ratio of people having same iris structure is 1:10^78 we have adopted this mechanism. Thus providing biometric security, we sign to bring secured democracy in our nation.

Abstract:In the years ahead we will witness machines with intelligence more powerful than that of humans. This will mean that robots, not humans, make all the important decisions. It will be a robot dominated world with dire consequences for humankind. The question is - Is there an alternative way ahead?

Humans have limited capabilities. Humans sense the world in a restricted way, vision being the best of the senses. Humans understand the world in only 3 dimensions and communicate in a very slow, serial fashion called speech. But can this be improved on? Can we use technology to upgrade humans?

The possibility exists to enhance human capabilities. To harness the ever increasing abilities of machine intelligence, to enable extra sensory input and to communicate in a much richer way, using thought alone. This possibility is made possible in the form of Cyborgs. A Cyborg is a Cybernetic Organism, part human part machine; it thrives on the inputs both from the living senses and from the machine interface, which acts as an enhancement module.

Dr. Kevin Warwick heads the Cybernetics Department at the University of Reading in the United Kingdom and has taken the first steps on this path, using himself as a guinea pig test subject receiving, by surgical operation, technological implants connected to his central nervous system.

Abstract: DNA computing holds out the promise of important and significant connections between computers and living systems, as well as promising massively parallel computations. Before these promises are fulfilled, however, important challenges related to errors and practicality have to be addressed. On the other hand, new directions toward a synthesis of molecular evolution and DNA computing might circumvent the problems that have hindered development, so far.

Abstract: The credential part of this paper gives the theoretical application of nanodevices in the treatment of cancer. The latest technology for the treatment cancer is the chemotherapic treatment in which drugs of specific composition is given to the patients depending on the biopsy of the tumor from the patient. The main disadvantage of using chemotherapy is that the drug used is not so specific and hence it causes damage to the surrounding healthy cells. It uses MAb, the monoclonal antibodies to locate the affected areas. To make the treatment more specific, we use the nanodevices that use nanosensors to be more specific in application of chemotherapy to the malignant tumors, thereby increasing the safety in usage of chemotherapic drugs. Also the use of biomotors in the nanodevices increases the oxygen content in the surrounding that decreases the hypoxia environment. This is given more importance because the angiogenesis or blood vessel formation for tumors is activated in a low oxygen environment or hypoxia. Also we could make specific compounds that could be carried along with the nanodevices that control the telomerase production, which could serve as a means of controlling cell division.

This paper is only a theoretical analysis given and all the information provided are specifically organized by us with help from a cancer patient, her doctor and a microbiology student. We sincerely thank them for their cooperation with us, for our paper.

Abstract: Red Acton is an exciting new technology for human area networking. We have developed a transceiver that uses the human body as a data transmission medium based on an electric-field sensor that uses an electrooptic crystal and laser light. Using this transceiver, we succeeded in achieving 10BASE communication in accordance with IEEE 802.3 through a human body from one hand to the other hand. While our immediate objective is to implement a Red Tacton system supporting two-way intra body communication at a rate of 10 M bit/s between any two points on the body, our longer-term plans include developing a mass-market transceiver interface supporting PDA’s s and notebook computers while continuing efforts to reduce the size and power consumption of the transceiver to enhance its portability. In the past, Bluetooth, infrared communications (IrDA), radio frequency ID systems (RFID), and other technologies have been proposed to solve the "last meter" connectivity problem. However, they each have various fundamental technical limitations that constrain their usage, such as the precipitous fall-off in transmission speed in multi-user environments producing network congestion. Thus this problem has been solved by the red tacton and has made it very innovative.

Abstract: This paper presents a robust and real-time capable recognition system for the fast detection and classification of objects in spatial 3D data. Depth and reflection data from a 3D laser scanner are rendered into images and fed into a saliency-based visual attention system that detects regions of potential interest. Only these regions are exanimate by a fast classifier. The time saving of classifying objects in salient regions rather than in complete images is linear with the number of trained object classes. Robustness is achieved by the fusion of the bi-modal scanner data; in contrast to camera images, this data is completely illumination independent. The recognition system is trained for two different object classes and evaluated on real indoor data.

Abstract:Nanorobotics is the technology of creating machines or robots at or close to the scale of a nanometer (10-9 meters). More specifically, Nanorobotics refers to the still largely theoretical nanotechnology engineering discipline of designing and building Nanorobots. Nanorobots (or nanobots) are typically devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components. Nanorobotics is also sometimes used to refer to attempts to miniaturize robots or machines to any size, including the development of robots the size of insects.

Abstract: Nanorobots are nanodevices that will be used for the purpose of maintaining and protecting the human body against pathogens. Nano is one billionth of one centimeter. Nanotechnology is the technology in which the operations are performed on nanometrics. It is the application of different technologies primarily interested in the reduction of size.

The credential part of this paper gives the theoretical application of nanodevices in the treatment of AIDS. There is no technology for the treatment of AIDS. Some of the drugs of specific composition are given to the patients depending on the intensity of the disease. The drugs using nowadays are able to increase the lifetime to a few years only. To make the treatment more specific, we use the nanodevices that use nanosensors to sense the AIDS infected WBC’s. In this we are using nanorobots to get back the HIV infected WBC’s. By doing so constant levels of WBC’s are maintained in the blood stream. Thus the AIDS patient is provided with the immune system so that he can defend himself from diseases.

In this paper only a theoretical analysis is given and all the information provided are specifically organized by us. In India more than 50 lakhs of people are infected by this dreaded disease and it constitutes 10% of the total infected. We are doing research on this paper and we hope that this theoretical approach can be made practical in the near future, so that the killer disease AIDS could also be made in control on the hands of Human with the emerging new technology like NANOTECHONOLOGY which has a Bio-medical Application.

Abstract: The word semantic implies meaning or, as WordNet defines it, “of or relating to the study of meaning and changes of meaning.” For the Semantic Web, semantic indicates that the meaning of data on the Web can be discovered—not just by people, but also by computers. In contrast, most meaning on the Web today is inferred by people who read web pages and the labels of hyperlinks, and by other people who write specialized software to work with the data. The phrase the Semantic Web stands for a vision in which computers—software—as well as people can find, read, understand, and use data over the World Wide Web to accomplish useful goals for users.

Of course, we already use software to accomplish things on the Web, but the distinction lies in the words we use. People surf the Web, buy things on web sites, work their way through search pages, read the labels on hyperlinks, and decide which links to follow. It would be much more efficient and less time-consuming if a person could launch a process that would then proceed on its own, perhaps checking with the person from time to time as the work progressed. The business of the Semantic Web is to bring such capabilities into widespread use.

In brief, the Semantic Web is supposed to make data located anywhere on the Web accessible and understandable, both to people and to machines. This is more a vision than a technology. In this book, we’ll explore the technologies that will play roles in bringing the vision to life.

Abstract: The problem with majority of data on the web is that it is difficult to use on a large scale, because there is no global system for publishing data in such a way as it can be easily processed by anyone. Everyone using the WWW has the problem that who can you trust to send you e-mails; how can I know sure if a transaction really occurred. So the semantic web can be seen as a huge engineering solution… but it is more than that.

The Semantic Web is a mesh of information linked up in such a way as to be easily procesable by machines, on a global scale. The Semantic Web provides a common framework that allows data to be shared and reused across application. It is a collaborative effort led by W3C. The Semantic Web is about common formats for integration and combination of data drawn from diverse sources, where the original Web mainly concentrates on the interchange of documents.

The Semantic Web approach instead develops languages for expressing information in a machine processable form. This development of Semantic Web is occurring in at least two areas: from the infrastructural, all-embracing, position as espoused by the W3C/MIT and other academically-focused organizations.

Our paper describes the details of Semantic Web and its need, ontologies, OWL, semantic web services and its applications- mainly FOAF which provides template for metadata about the people and their interests. However Semantic Web technologies are still very much in their infancies, and the future of the project in general appears to be bright.

Abstract:Knowledge management (KM) is useful for the organizations to create, capture and reuse knowledge to achieve organizational objectives. The Semantic Web is a technology that enables KM and it is the future of the current web, which will retrieve accurate information based on the machine processable semantics of the data. Ontologies provide metadata description to domain specific knowledge bases. The languages available for making ontologies are RDF, OWL and DAML+OIL. Till now the ontologies are available for several domains of study such as gene ontology, amino-acid ontology, family relations ontology, camera ontology, wine ontology, etc. This paper describes the construction of an ontology for the domain of Cryptography in DAML+OIL language. This will help the human users to utilize the Semantic Web for their knowledge needs in the Cryptography domain

Abstract: The wrist watch pulse monitor is a device, which can be worn around the wrist to monitor the pulse rates and alert us in case of any abnormality in the operation of heart. It basically uses a sensor and a micro controller. The sensor senses the pulse rate and the micro controller displays the pulse rate and indicates when the pulse rate is abnormal. In addition to this the wrist watch is provided with an identification code which gives the patient details like age, address etc., this helps in providing the right kind if treatment for the patient .This saves precious time incase of emergency. As the ideal pulse rate varies with age and is different when you exercise, the device has a mode select option where you can select between normal and exercise mode. Also there are various age ranges from which you can set the device to suit your own age.
