With the exception of the Great Wall of China, dams are the largest structures ever built.Throughout history, big dams have prevented flooding, irrigated farmland, and generated tremendous amounts of electricity. Without dams, modern life as we know it would simply not be the same.Since the first large-scale dam was built in Egypt more than 5,000 years ago, engineers have devised various types of dams to withstand the forces of a raging river....

We report in this paper our study of Spanning Tree Protocols. Spanning Tree protocols are link management protocols that provide path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations.Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur,some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.To incorporate the required feature of Redundancy and at the same time to avoid broadcasting storms from congesting the network, spanning tree protocols are used.IEEE is one of the most widely recognized standarazation bodies in computer science.IEEE 802 refers to a family of IEEE standards about local area networks and metropolitan area networks.One of its standard is IEEE 802.1, standard for MAC layer & Internetworking Devices. In this report we report our study of the 802.1d (STP),802.1w (RSTP) & 802.1s (MSTP) which are Spanning tree protocols implemented in Routers and Switches....[Read details]

Multi hazard Risk analysis is concerned with the performance of structures subjected to multiple random loads, some of which may occur simultaneously. Separate investigations of single processes only might lead to a misjudgment of the general risks for these offshore structures.To avoid this trap, risk assessments should not focus on a singular process but on multiple processes. Within this study a general methodology is developed to analyze risk for multiple processes.To focus and illustrate the presentation of the methodology, we will examine a simple model of an offshore structure subjected to earthquake shaking and sea-storm-generated wind,wave and current loads .Also we will compute the integrated risk in he presence of multiple loads and determine the relative importance of different loads in function of both the structural and load characteristics....[Read details]

Dead spots are everywhere. They're those areas of your home or office where, no matter how you position your router or how you point the antenna, you just can't get a Wi-Fi signal. Almost any Wi-Fi connection, even a weak one, is sufficient to surf the Internet or transfer data. But if distance and obstacles sap too much bandwidth from a network, video images will start to stutter and break up. Video is what's causing this problem on range and higher speed. The cure for the problem, is an innovation called MIMO, short for multiple input, multiple output .The new technology, uses a number of antennas to send multiple signals as a way to significantly increase the speed and range of a wireless network. In tests 's it is found that MIMO nearly doubled the speed and provided superior range. Multiple-Input / Multiple Output (MIMO) technology has emerged in the last decade as a powerful means of increasing the throughput and performance of wireless communication systems....[Read details]

Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant packet losses due to bit errors and handoffs. TCP responds to a packet loss by invoking congestion control and avoidance algorithms, resulting in degraded end-to-end performance in wireless and lossy systems.There are various protocols proposed based on different schemes and the modes of operation. In this report, we discuss some of these methods, and do a qualitative study of their performance using throughput as a performance metric....[Read details]

As it applies to cancer, immunotherapy might be considered a revolutionary form of medicine but its roots actually go back as far as 1778, when Edward Jenner, an English physician, administered the first vaccine, which was targeted against smallpox.Tumor immunotherapy is an anticancer approach in which the patient’s immune system is either prodded or cajoled to fight tumors. Over time, our understanding of the immune system and tumor immunology has increased and this has enabled scientists to develop the ability to apply specific immunotherapies designed to enhance the immune response of a particular patient against unique targets....[Read details]

All living things are made of cells. Cells work together to form organs. Each cell has a control center called a nucleus. The nucleus contains the information that tells the cell what to do and when to grow and divide. This information is contained in genes, which are the building blocks of chromosomes. In the nucleus of each human cell (except for sperm and egg cells), there are 23 pairs of chromosomes. Chromosomes are made up of long strands of a substance called DNA (deoxyribonucleic acid), which is a collection of molecules called bases arranged in a certain sequence. Within each chromosome, there are many hundreds to thousands of genes. Genes are segments of DNA that tell the cell to do a specific task, usually to make a particular protein. Each protein has a specific job or function in the body. Each human cell has about 30,000 genes; each one makes a protein with a unique function. ...[Read details]

Corporations are beginning to use wireless LANs to carry voice and video, increasing the need for speed, capacity and reliability. But because WLANs share a finite allocation of frequency spectrum, without increased spectral efficiency they will consume all the available frequency channels and interfere with one another - becoming victims of their own success. Multiple-Input / Multiple Output (MIMO) technology has emerged in the last decade as a powerful means of increasing the throughput and performance of wireless communication systems. Research on this relatively new technology has penetrated in a substantial way many fields, ranging from signal processing to information / communication theory to wireless propagation. Equally importantly, MIMO technology has made its way into current and next generation communication standards and systems.Multiple-input multiple-output (MIMO) systems are today regarded as one of the most promising research areas of wireless communications. This is due to the fact that a MIMO channel can offer a significant capacity gain over a traditional single-input single-output (SISO) channel....

Although all the Group VIII metals are catalytically active in the hydrogenation of carbon oxides to form methane ("methanation"), nickel remains the favored catalyst for the reaction by virtue of its life, high activity, selectivity towards methane formation in preference to other hydrocarbons, and it’s comparatively low cost. Supported nickel catalysts are preferred on account of their thermal and mechanical stability. In this paper, Ni/Al2O3 catalyst is discussed at length and subsequently its effect on methanation reaction along with the mechanism is also explained. TPR of Ni/alumina catalysts gives evidence that they have 2 sites for reaction, surface NiO and a form of NiAl2O4.Methanation of CO proceeds via dissociation on nickel catalyst and the surface carbon species thus formed are hydrogenated to methane. CO2 methanation proceeds via conversion of CO2 to CO via the reverse water gas shift reaction followed by CO methanation....[Read details]

Machine recognition of human face is an active and fast growing area of research due to a wide variety of commercial and law-enforcement applications including access control, security monitoring, and video surveillance. The major advantage of this biometric approach is its ability for authentic identification of a person’s identity. While the established and widely used authentication criteria such as passwords, PINs (Personal Identification Numbers) or magnetic cards suffer from the risk of getting stolen, copied, lost and are thus exposed to fraudulent use biometric approaches are expected to be immune from this drawback. Among the various biometric approaches, face recognition offers the additional advantage in that this approach allows a passive and non-intrusive identification in a user-friendly way without having to interrupt user activity. We provide, in this report, a brief overview of the techniques being explored for developing a face recognition system and indicate the present state-of-the-art of the field....

With the environment and cost issues surrounding conventional chemical processes being subjected to considerable scrutiny, biotechnology is rapidly gaining ground due to the various advantages it offers over the conventional technologies. Industrial enzymes represent the heart of biotechnology processes.Proteolytic enzymes catalyze the cleavage of peptide bonds in other proteins. Proteases are degradative enzymes which catalyze the total hydrolysis of proteins. Advances in analytical techniques have demonstrated that proteases conduct highly specific and selective modifications of proteins such as activation of zymogenic forms of enzymes by limited proteolysis, blood clotting and lysis of fibrin clots, and processing & transport of secretory proteins across the membranes. The global market for industrial enzymes was estimated at $2 billion in 2004 and is expected to raise at an average annual growth rate (AAGR) of 3.3% to $2.4 billion in 2009, (source BCC 2004)...[Read details]

The “Remote Sensing” technique proves itself as a boom in an economic development all over. This technical paper briefly deals with application and result of remote sensing techniques and its types. As we know that “Remote Sensing” is the science and art of acquiring information (spectral, spatial, temporal) about material objects, area, or phenomenon, without coming into physical contact with the objects, or area, or phenomenon under investigation. Without direct contact, some means of transferring information through space must be utilized. In remote sensing, information transfer is accomplished by use of electromagnetic radiation (EMR). EMR is considered to span the spectrum of wavelengths from 10-10 mm to cosmic rays up to 1010 mm, the broadcast wavelengths, which extend from 0.30-15 mm....

This results in a significant reduction in ISI (inter symbol interference) and complexity of the equalizer. It can adopt different modulation and signaling formats, that makes it more favorable. Here we have discussed low power allocation technique for clustered multi-band OFDM networks. The idea is to assign power to each cluster while maximizing the total throughput.

A large no. of projects get cancelled and never reach to completion with even more money being spent than estimated earlier. Only few of a thousand projects are completed on time and on budget. There are many challenges involved while developing a large business application like huge amounts of data, user code etc. As a result, building business applications requires technical knowledge about database design, entity relationship or object modeling, GUI design, middleware technology, programming languages, operating systems, prototyping tools, and so on. Managing a development environment and a knowledgeable team capable of tackling a large application is a crucial consideration to be weighed carefully while starting a new project. Some commonly desired characteristics which are required for optimization are Performance, Scalability, Flexibility, Availability and Portability. There are some requirements for large project success viz. proper planning, Management support, Clear statement of requirements and the ability to verify them and User involvement. A representative approach for developing a large object-oriented application is required which includes Architecture, Server development, Interface development, Interface development process, Testing, Software performance engineering, Configuration management, Project management etc. DBMS is required in each and every field.

Bioinformatics is an integration of mathematical, statistical and computer methods to analyze biological, biochemical and biophysical data. Roughly, bioinformatics describes any use of computers to handle biological information. In practice the definition used by most people is narrower; bioinformatics to them is a synonym for "computational molecular biology"--- the use of computers to characterize the molecular components of living things. It is the science of developing computer databases and algorithms for the purpose of speeding up and enhancing biological research. Bioinformatics is being used most noticeably in the Human Genome Project, the effort to identify the 80,000 genes in human DNA .

The two major abnormal combustion processes are Knock and Surface. Knock in S.I. engines is very significant phenomenon as it severely affects the life and performance of the engines. The basic cause of 'knock', the high pitched metallic noise, is the auto ignition of the charge left ahead of the advancing flame front . Due to auto ignition propagation of pressure waves of high amplitude takes place, which leaves resonating combustion chamber. They can even cause engine damage due to high temperatures and pressures. Two theories are proposed which try to give the cause of origin of knock. They are the Auto ignition theory and the Detonation theory. The other abnormal combustion phenomenon is 'Surface Ignition'. It is the ignition of charge by hot spots, if it is before spark plug ignites the charge (pre-ignition) and if after then (post-ignition). Different surface ignition phenomenon are wild ping, run on, run away, rumble, etc. Pre-ignition is potentially the most damaging surface ignition phenomenon. It usually occurs due to spark plug and combustion chamber deposits Due to which piston seizure, destruction of piston rings etc. occurs.Knock can be prevented by many ways, e.g. by retarding spark timing, by using high Octane rated fuel etc....[Read details]

VLSI stands for "Very Large Scale Integrated Circuits". It's a classification of ICs. An IC of common VLSI includes about millions active devices. Typical functions of VLSI include Memories, computers, and signal processors, etc.A semiconductor process technology is a method by which working circuits can be manufactured from designed specifications. There are many such technologies, each of which creates a different environment or style of design. In integrated circuit design, the specification consists of polygons of conducting and semiconducting material that will be layered on top of each other to produce a working chip. When a chip is custom-designed for a specific use, it is called an application-specific integrated circuit (ASIC). Printed-circuit (PC) design also results in precise positions of conducting materials, as they will appear on a circuit board; in addition, PC design aggregates the bulk of the electronic activity into standard IC packages, the position and interconnection of which are essential to the final circuit. Printed circuitry may be easier to debug than integrated circuitry is, but it is slower, less compact, more expensive, and unable to take advantage of specialized silicon layout structures that make VLSI systems so attractive....[Read details]

A computer virus is a small program written by an ill intentioned hacker meant only to ruin someone’s day. A computer virus is a program that can "infect" other programs by modifying them to include a copy of it. Viruses can also contain instructions that cause damage or annoyance; the combination of possibly damaging code with the ability to spread is what makes viruses a considerable concern. For example, they can trigger after a specific number of executions or on a specific date, such as Friday the 13th or April 1st or can occur at random. Depending on the motives of the virus author, a virus can contain no intentionally harmful or disruptive instructions. Or, it can cause damage simply by replicating itself and taking up scarce resources, such as hard disk space, CPU time, or network connections. Some typical things that some current Personal Computer (PC) viruses do are:...[Read details]

Jini defines a new concept known as “spontaneous networking”. Jini is designed to allow a whole range of electronics devices – from handheld computers and cellular phones to VCRs and dishwashers – to "talk" to each other in a network and share information and resources regardless of their underlying operating system or hardware.But what exactly is Jini? Jini is both an architecture and a set of Application Programming Interfaces (API – a set of standard functions that can be used in application programs to implement a well defined set of tasks) that define how various devices will be interconnected using the Java Platform. Jini network technology provides simple mechanisms which enable devices to plug together to form an impromptu community – a community put together without any planning, installation, or human intervention. Each device provides services that other devices in the community may use. These devices provide their own interfaces, which ensures reliability and compatibility...[Read details]

Wireless is information technology that employs electronic, magnetic and acoustic waves to transmit data through space without using a physical wire. Radios, televisions, fax machines, cellular telephones, pagers, and the wireless Internet each exemplify the practical application of wireless technology. Wireless communications represent a convergence of computers, the Internet, and telecommunications into a single medium that gives its users mobility and flexibility. As a result of that a new-world, wireless IP–based network model being developed jointly by two of the world’s leading communications enterprises: one in the wireless communications industry and the other in the [INTERNET PROTOCOL] IP–based Internet communications business. Together, these two enterprises are creating a mobile wireless IP network that meets tomorrow’s requirements by providing opportunities previously only imagined. Among such opportunities is the ability to make wireless an integral part of the Internet—rather than just another access technology. ...[Read details]

The web is an inherently open system.. It derives most of its utility and popularity from its openness, which means that it is open not only to useful and co-operative elements ,but also to abuse. the very fact that a web server is connected to the internet and is well publicized , increases the risk of attracting unwanted attention to the system on which it runs. thus we need to secure our system.Thus there are some basic questions which arise in our minds now that we have started:what are we actually trying to protect , from whom are we trying to protect or lets say what actually are the type of attacks, what the secure system should basically comprise and finally the methods that can be afforded?...[Read details]

The popular conception of software piracy is that it is the activity of a minority of isolated pirate-hobbyists, copying and trading software for their personal consumption. Microsoft's allegations reflect a reality that software piracy has expanded from the bedrooms of computer wiz kids to a global trade in stolen software accounting for untold billions of dollars in lost revenue to the software industry. But Microsoft's statement is even more telling, in that it indicates the impact of software piracy goes far beyond lost income for software company shareholders. It affects lost jobs in local economies, lost tax revenues to governments, and decreased quality and increased prices for consumers whether private individuals, educational institutions, or businesses....[Read details]

As more and more people begin using Web sites as a way to get information or do business, Web site performance under heavy loads becomes more critical. Although the cost of computer equipment has decreased as the speed and capacity of computer equipment has increased, site managers can't afford to buy incorrect or unnecessary equipment while trying to boost site performance. By using the performance counters built into Windows NT® and Internet Information Server (IIS), managers can monitor performance to determine equipment needs. After changes are made, monitoring can be used to determine if they had the desired effect, or if further changes are needed. This article describes which performance counters to use to determine when to tune or upgrade hardware. The four areas of computer hardware discussed in this article are:...[Read details]

Although memory is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage. If your computer's CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the data are kept in memory, the CPU can access data much more quickly. Most forms of memory are intended to store data temporarily....[Read details]

Accurate machine vision opens up a new realm of computer applications. These applications may include mundane tasks like perception and mobile robot navigation to expert systems like complex manufacturing tasks, analysis of satellite images and medical image processing.Transforming raw camera images into useful information about the world is, however, a complex and challenging task in the field of Computer Image Processing. This is so because the images are two-dimensional and the world is three-dimensional.In this paper we have tried to explain a method to derive 3D co-ordinates from measurements and constituents (geons) of 2D images.Given a single 2D image it is possible to construct any number of 3D worlds that would give rise to the image. As a result 2D images are highly ambiguous and it becomes difficult to decide what 3D object the image portrays.In order to determine the most likely interpretation of the 2D image, the knowledge of low-level image features is essential. We have used multiple simultaneous views of the object from different cameras to accomplish this. Such a technique is called stereovision....[Read details]

In information technology, a Neural Network (NNs) is system of programs & data structures that approximates the operation of the human brain. A Neural Network usually involves a large no. Of processors operating in parallel, each with its own small sphere of knowledge and access to data in its local memory. Typically a Neural Network is initially “trained” or fed large amounts of data and rules about data relationships, for example, a grandfather is older than a person’s father. A program can then tell the network how to behave in response to an external stimulus or can initiate activity on its own. In making determinations, a neural networks use several principles, including gradient based training, fuzzy logic, genetic algorithms and Bayesian methods. Neural networks are sometimes described in terms of knowledge layers with, in general, more complex networks having deeper layers. Neural Networks can also learn temporal concepts and have been widely used in signal processing and time series analysis. Current applications of neural networks include: Oil Exploration Data Analysis, Weather Prediction, The Interpretation of nucleotide sequences in biology labs, and the exploration of models of thinking and consciousness....[Read details]
