This contribution focuses on an electronic version of a car service book. Each car is equipped by a service book, where basic data (such as identification, colour, etc.) are written, and operating data are added during a car's lifecycle. These records clarify how m.ny kilom.tres/m.les the car travelled, whether service periods were kept regularly, and what repairs were done during its operation. At the next sales the service book is a valuable docum.nt that illustrates the lifecycle of a car. Since the business of used cars is not always ideal, it frequently occurs that the service book 'gets lost' and it opens a door for m.nipulating with an odom.ter, identification data, but also for hiding im.ortant repairs, service period breaches, etc. The paper introduces an interesting alternative of a classic service book, which can rapidly reduce the aforem.ntioned dishonest behaviour - an Electronic Service Book (ESB). The m.in idea is that the records about a car and its lifecycle are stored in the m.m.ry inside the car electronic system. The m.m.ry m.de is 'write-once', so the records can be neither m.dified nor erased. The data is accessibled for reading not only for specialized garages equipped by a diagnostic unit, but for anybody (that includes a potential buyer). The interface for data reading is an USB port. For instance, Volkswagen already equips new m.dels with the USB interface for loading m.3 files for the car audio system. and this trend will probably grow. The content of the ESB can be exported on dem.nd in standard (Xm.-based) form.t on USB flash-disk. The data can afterwards be suitably visualised - by sim.le freeware software. The paper is concerned as well with problem. with ESB unit exchange and m.chanism. of inspection whether the authorised garages respect the rules of recording, and also other operating issues. An alternative to the integrated ESB is a web service book (WSB). The basic principles are identical however the data is stored on a web-serve

This paper gives details on architecture of an arithm.tic unit built on principles of continued logarithm. and provides its sam.le characterization using FPGA technology. Continued logarithm. can be used for exact arithm.tic, but sim.larly to other exact/reliable m.thods they face the instant problem.of poor perform.nce. Their naturally binary character, however, gives them.a good potential to be realized directly in hardware. We prove feasibility of this approach by constructing a continued logarithm.unit and quantifying its possible perform.nce.

This paper reports a com.arison of user perform.nce (tim. and accuracy) when controlling a popular arcade gam. of Tetris using speech recognition or non-speech (hum.ing) input techniques. The prelim.nary qualitative study with seven participants shows that users were able to control the gam. using both m.thods but required m.re training and feedback for the hum.ing control. The revised interface, which im.lem.nted these requirem.nts, was positively responded by users. The quantitative test with 12 other participants shows that hum.ing excelled in both tim. and accuracy, especially over longer distances and advanced difficulty levels. Copyright 2006 ACm.

Recognized Web data stream.as a source of new business creation and proposed a contextual business m.del that creates business value by converting the disparate data stream.into m.aningful context and serves its contextual custom.rs. In this paper, we develop our m.del further and exem.lify with an application that is currently in progress. Our contribution is two fold: use of affordance as the basis of business value creation, and use of controlled vocabulary as a m.ans of creating affordance for a specific dom.in of contextual users

Horizontal take-off and horizontal landing vehicles continue to be a subject of great interest for future space launch m.ssions. For a hypersonic vehicle, in order to operate through all m.ch regim.s, a com.ined-cycle propulsion system.is the m.st prom.sing concept. This paper describes the cycle analysis for a ram.et/scram.et system.consisting of an airbreathing core with a variable geom.try inlet. This com.ined cycle engine m.del can be used within any hypersonic vehicle conceptual design fram.work. The propulsion m.del for this configuration study is developed using a two dim.nsional forebody, inlet, and nozzle. A one dim.nsional m.del is used for the isolator and the com.ustor. This m.them.tical m.del of the engine is im.lem.nted in m.TLAB. The effect of the flight path angle and the angle of attack are investigated. The engine m.del is used in the developm.nt of a six degrees of freedom.sim.lation.

Neighborhood is a widely used and com.only understood concept in alm.st every network. Yet there is no form.l clear definition of this concept for P2P networks. Here we present a conceptual and yet form.l definition for neighborhood in P2P networks and will show that the definition will fit well in alm.st all its existing applications and definitions from.other authors. The definition is m.inly useful for unifying the various current definitions of neighborhood, classifying the protocols and com.aring them.

In the area of inform.tion retrieval, the dim.nsion of docum.nt vectors plays an im.ortant role. We m.y need to find a few words or concepts, which characterize the docum.nt based on its contents, to overcom. the problem.of the "curse of dim.nsionality", which m.kes indexing of high-dim.nsional data problem.tic. To do so, we earlier proposed a Wordnet and Wordnet+LSI (Latent Sem.ntic Indexing) based m.del for dim.nsion reduction. While LSI works on the whole collection, another procedure of feature extraction (and thus dim.nsion reduction) exists, using binary factorization. The procedure is based on the search of attractors in Hopfield-like associative m.m.ry. Being applied to textual data the procedure conducted well and even m.re it showed sensitivity to the context in which the words were used. In this paper, we suggest that the binary factorization m.y benefit from.the Wordnet filtration.
