FireWire

Introduction
FireWire (also known as i.Link or IEEE 1394) is a personal computer (and digital audio/digital video) serial bus interface standard, offering high-speed communications and isochronous real-time data services. FireWire has replaced Parallel SCSI in many applications due to lower implementation costs and a simplified, more adaptable cabling system. Almost all modern digital camcorders have included this connection since 1995.

Many computers intended for home or professional audio/video use have built-in FireWire ports including all Macintosh, Dell and Sony computers currently produced. FireWire was also an attractive feature on the Apple iPod for several years, permitting new tracks to be uploaded in a few seconds and also for the battery to be recharged concurrently with one cable. However, Apple has eliminated FireWire support in favor of Universal Serial Bus (USB) 2.0 on its newer iPods due to space constraints and for wider compatibility.
Neuroprosthetics
Neuroprosthetics

Introduction
Neuroprosthetics is an area of neuroscience concerned with neural prostheses, that is, artificial devices used to replace or improve the function of an impaired nervous system. The neuroprosthetic seeing the most widespread use is the cochlear implant, which is in approximately 85,000 people worldwide as of 2005.

An early difficulty in the development of neuroprosthetics was reliably locating the electrodes in the brain, originally done by inserting the electrodes with needles and breaking off the needles at the desired depth. Recent systems utilize more advanced probes, such as those used in deep brain stimulation to alleviate the symptoms of Parkinsons Disease. The problem with either approach is that the brain floats free in the skull while the probe does not, and relatively minor impacts, such as a low speed car accident, are potentially damaging.

Some researchers, such as Kensall Wise at the University of Michigan, have proposed tethering 'electrodes to be mounted on the exterior surface of the brain' to the inner surface of the skull. However, even if successful, tethering would not resolve the problem in devices meant to be inserted deep into the brain, such as in the case of deep brain stimulation [DBS].
MeSCoDe
MeSCoDe

Introduction
File Management is a very relevant application in computer field. ?MeSCoDe? software focuses on splitting files in a user friendly manner, merging different source files into a single one, compressing a file that can save large extend of memory decompressing compressed files to produce the original file. Compression and decompression are very useful for durable data.

The software named ?MeSCoDe? has been developed using C++. The title ?MeSCoDe? is the abbreviation of Merging, Splitting, Compression and Decompression. All these facilities can be done using MeSCoDe?.
Mobile agent
Mobile agent

Introduction
In computer science, a mobile agent is a composition of computer software and data which is able to migrate (move) from one computer to another autonomously and continue its execution on the destination computer. Mobile Agent, namely, is a type of software agent, with the feature of autonomy, social ability, learning, and most important, mobility.

When the term mobile agent is used, it refers to a process that can transport its state from one environment to another, with its data intact, and still being able to perform appropriately in the new environment. Mobile agents decide when and where to move next, which is evolved from RPC. So how exactly does a mobile agent move? Just like a user doesn t really visit a website but only make a copy of it, a mobile agent accomplishes this move through data duplication. When a mobile agent decides to move, it saves its own state and transports this saved state to next host and resume execution from the saved state.

Mobile agents are a specific form of mobile code and software agents paradigms. However, in contrast to the Remote evaluation and Code on demand paradigms, mobile agents are active in that they may choose to migrate between computers at any time during their execution. This makes them a powerful tool for implementing distributed applications in a computer network.

Advantages

1) Move computation to data, reducing network load.

2) Asynchronous execution on multiple heterogeneous network hosts

3) Dynamic adaptation - actions are dependent on the state of the host environment

4) Tolerant to network faults - able to operate without an active connection between client and server

5) Flexible maintenance - to change an agent s actions, only the source (rather than the computation hosts) must be updated

Applications

1) Resource availability, discovery, monitoring

2) Information retrieval

3) Network management

4) Dynamic software deployment
Diesel Particulate Filter
Diesel Particulate Filter

Introduction
A Diesel Particulate Filter, sometimes called a DPF, is device designed to remove Diesel Particulate Matter or soot from the exhaust gas of a Diesel engine, most of which are rated at 85% efficiency, but often attaining efficiencies of over 90%. A Diesel-powered vehicle with a filter installed will emit no visible smoke from its exhaust pipe. In addition to collecting the particulate, a method must be designed to get rid of it.

Some filters are single use (disposable), while others are designed to burn off the accumulated particulate, either through the use of a catalyst (passive), or through an active technology, such as a fuel burner which heats the filter to soot combustion temperatures, or through engine modifications (the engine is set to run a certain specific way when the filter load reachs a pre-determined level, either to heat the exhaust gasses, or to produce high amounts of No2, which will oxidize the particualte at relatively low temperatures). This procedure is known as 'filter regeneration.' Fuel sulfur interferes many 'Regeneration' strategies, and all jurisdictions that are interested in reduction of particulate emissions, are also passing regulations governing fuel sulfur levels.
Hybrid Synergy Drive (HSD)
Hybrid Synergy Drive (HSD)

Introduction
Hybrid Synergy Drive (HSD) is a set of hybrid car technologies developed by Toyota and used in that company's Prius, Highlander Hybrid, Camry Hybrid, Lexus RX 400h, and Lexus GS 450h automobiles. It combines the characteristics of an electric drive and a continuously variable transmission, using electricity and transistors in place of toothed gears. The Synergy Drive is a drive-by-wire system with no direct mechanical connection between the engine and the engine controls: both the gas pedal and the gearshift lever in an HSD car merely send electrical signals to a control computer.

HSD is a refinement of the original Toyota Hybrid System (THS) used in the 1997“2003 Toyota Prius. As such it is occasionally referred to as THS II. The name was changed in anticipation of its use in vehicles outside the Toyota brand (Lexus). When required to classify the transmission type of an HSD vehicle (such as in standard specification lists or for regulatory purposes), Toyota describes HSD-equipped vehicles as having E-CVT (Electronically-controlled Continuously Variable Transmission).
Design Pattern Visualization for Program Comprehension
Design Pattern Visualization for Program Comprehension

Introduction
In recent years the usage of design patterns is gaining interest in the software design community. Design patterns provide successful and proven solutions for design problems and common terminologies that are based on the expertise of domain experts, thus providing guidance for both design and comprehension of large-scale software systems. In this presentation we focus on the visualization of design patterns that were recovered from existing source code.

In particular we discuss three popular approaches in graph drawing and their applicability to visualize patterns since generating layouts for design patterns can be seen as a graph-drawing problem. The presentation will conclude with some discussion on open problems and some potential future directions to address the challenges of visualizing design patterns

PLATONIS - A Validation Platform for Protocols and Services
PLATONIS - A Validation Platform for Protocols and Services

Introduction
Advance in network technology leads to the design of new protocols and services. In order to assure successful communication among those new products, testing and validation activities for conformance and interoperability play an important role in the development and deployment of them.

In this lecture, we introduce the PLATONIS platform, a platform for validation and experimentation of new protocols and services. The platform is focused on WAP protocols and services, but it is expected to be general enough to be used for other protocols and services such as those of GPRS, UMTS, and wired networks
Positive Extension Matrix
Positive Extension Matrix

Introduction
¢ The extension matrix method is that at first, we find the distinguishing between the positive examples and negative examples. The extension matrix is used to represent those distinguishes, and then according to those distinguishes, the examples are induced so that the proper assertions are obtained. The extension matrix clearly reflects the distinguishing between positive examples and negative examples. It is easy to find the heuristic of a problem relying on it.

¢ Nowadays there are AE1, AE5 , AE9 and AE11 algorithms that are created by relying on the extension matrix. All those algorithms are creating the heuristics starting from the nature of the path. In the algorithms, a rule is simplest with AE11, and it obtains the simpler rule than the AQ15. The algorithm AE18 we proposed in the paper also belongs to the extension matrix. It is based on the positive extension matrix (PEM). It also creates heuristics to induce starting from the nature of the path. In the inducing the algorithm prior selects the required elements.

¢ In order to optimize our positive matrix algorithm, this talk will presents the algorithm AE18 and makes comparisons with our experimental results
XML Data Compression
XML Data Compression

Introduction
XML is a popular meta-language that facilitates the interchange and access of data. However, XML's verbose nature tends to increase the size of a data file by as much as ten-fold.

In this seminars, we give a brief introduction to data compression followed by a review of various compression strategies designed specifically for XML data. We then present two novel XML compression techniques, AXECHOP and TREECHOP.

AXECHOP uses a grammar-based approach that exploits the significant structural redundancies within XML documents, while TREECHOP supports querying of compressed XML data without requiring prior decompression.

We compare these two techniques to other XML compression schemes with respect to compression ratio and compression time, and describe our future research.
Aspect Oriented Programming
Aspect Oriented Programming

Introduction
Object-oriented programming (OOP) has been presented as a technology that can fundamentally aid software engineering, because the underlying object model provides a better fit with real domain problems. However most software systems consist of several concerns that crosscut multiple modules. Object-oriented techniques for implementing such concerns result in systems that are invasive to implement, tough to understand, and difficult to evolve.

This forces the implementation of those design decisions to be scattered throughout the code, resulting in tangled code that is excessively difficult to develop and maintain. The new aspect-oriented programming (AOP) methodology facilitates modularization of crosscutting concerns. Using AOP, you can create implementations that are easier to design, understand, and maintain. Further, AOP promises higher productivity, improved quality, and better ability to implement newer features.
Cluster Computing
Cluster Computing

Introduction
A cluster is a type of parallel or distributed processing system, which consists of a collection of interconnected stand-alone computers co - operatively working together as a single, integrated computing resource. This cluster of computers shares common network characteristics like the same namespace and it is available to other computers on the network as a single resource.

These computers are linked together using high-speed network interfaces between themselves and the actual binding together of the all the individual computers in the cluster is performed by the operating system and the software used.
Dynamic Virtual Private Network
Dynamic Virtual Private Network

Introduction
The growth of the Internet has revolutionized communication facilities. Through years, more and more communication standards and facilities emerged; e-mail and faxing direct from and to PC are examples. Now the Internet has also crept into the world of business. It was there in the business for years but was not directly involved with it.

In order to accommodate new, changing and expanding groups of users and provide these users with information in a number of ways, intranets should deliver several benefits, including flexibility, interoperability, ease of use and extendibility. In particular, they should be open and and standards based, so information can be read by different users with different applications on different platforms.

However, the benefits promised by intranets lead to an important challenge for businesses using this technology: how to establish and maintain trust in an environment which was designed originally for free and open access to information. The Internet was not designed with business security in mind. It was designed by universities as an open network where users could access, share and add to information as early as possible. A way has to be found to secure an intranet for businesses without impinging on the intranetâ„¢s inherent benefits of flexibility interoperability and ease of use. Indeed, an ideal solution must also provide not only the highest levels of security but also security in such a way that users can easily access, modify and share more information, not less, under carefully controlled and maintained conditions.

The most appropriate and successful answer to this challenge will be a DYNAMIC VIRTUAL PRIVATE NETWORK. Unlike traditional VPNs that offer limited or inflexible security, a dynamic VPN provides both extremely high levels of security and, equally important, the flexibility to accommodate dynamically changing groups of users and information needs. A dynamic VPN is actually an intranet enabler. It enables an intranet to offer more resources and services than it could otherwise, thereby allowing the business to make more use of its information resources.
