Hypermedia systems and more specifically open hypermedia systems (OHS) provide a rich set of implementations of different hypertext flavors such as navigational hypertext, spatial hypertext or taxonomic hypertext. Additionally, these systems offer component-based modular architectures and address interoperability between hypertext domains. Despite multiple efforts of integrating Web clients, a widespread adoption of OHS technology by Web developers has not taken place. In this paper it is argued that Web Services - which offer a component model for Web applications - can be integrated in OHSs. An architectural integration is proposed, a step-by-step process is outlined and an example of integration is provided. This very approach is aimed to benefit both worlds: the Web community with new rich hypermedia functionality that extends the current navigational hypermedia, and the OHS community by opening its tools and platforms to the many developer groups of the Web community.

In this paper a systematic methodology for designing parallel-prefix modulo 2n - 1 adders, for every n, is introduced. The resulting modulo 2n - 1 adders feature minimum logical depth and bounded fan-out loading. Additionally, an optimization technique is proposed, which aims to the reduction of redundant operators that appear on the parallel-prefix carry computation trees. Performance data reveal that the reduced structures achieve area × time complexity reduction of up to 46% when compared to previously reported designs.

It has recently been shown that accumulators can be used efficiently for test pattern generation as well as for test response compaction. In this paper we present a BIST scheme for accumulators where the accumulator is simultaneously used as a test pattern generator and a response compactor during its own testing. We also show that the proposed BIST scheme is especially suitable for accumulator, adder and multiplier-accumulator RNS channels leading to minimal hardware overhead and short test sequences.

In this work we propose a new method for designing modulo 2/sup n/+l multipliers for diminished-1 operands. Our multipliers compared to the already known tree architecture offer enhanced operation speed for the majority of n values, with similar area complexities. They also have very regular structure, and can be pipelined at the full-adder level.

A systematic methodology for generating software-based self-tests for microprocessor cores is introduced in this paper. The produced software tests emulate the functionality of a scan path design, and can be applied during the normal-operation mode of the microprocessor, thus enabling at-speed testing. A major advantage of the proposed approach lies in the fact that the generation of the software tests does not require any knowledge about the low-level implementation of the microprocessor and is only based on its RT-level description and its instruction set architecture.

Configuration testing is an important step in software testing, which is a procedure to test the software with all kinds of hardware to ensure it can run on them. This paper proposes to design configuration testing plan with several common method used in the other fields and analysis their merits, to improve the orthogonal design method with pairwise testing, to decrease the testing risk with multiple factors covering., and presents simple factor cover method which can cover all the factors and pairwise combinations to the greatest degree. All these methods have good merits. At last we make some comparison at the aspects of test suit scale, coverage, usability and etc.

The design of tapered roller bearings has a fundamental influence on the performance, life and reliability of the bearings. Consequently, this also affects the operating quality and the economization of machines on which the bearings are used. The responsibility of bearing designers is to select an optimal scheme from all the possible alternative designs, or simply put to make the best choice. A basic requirement for conventional rolling bearings is the maximum dynamic capacity. In this paper we used Genetic Algorithm to search a design for tapered roller bearing, which has maximum dynamic capacity, and the design satisfies all the boundary conditions. The algorithm proceeds with basic objective of increase in dynamic capacity value. At the same time all the constraints are also satisfied.

This paper describes an experimental stereo vision based motion planning system for humanoid robots. The goal is to automatically generate arm trajectories that avoid obstacles in unknown environments from high-level task commands. Our system consists of three components: 1) environment sensing using stereo vision with disparity map generation and online consistency checking, 2) probabilistic mesh modeling in order to accumulate continuous vision input, and 3) motion planning for the robot arm using RRTs (Rapidly exploring Random Trees). We demonstrate results from experiments using an implementation designed for the humanoid robot H7.
