A new generation of intelligent applications can be enabled by broad-coverage repositories of knowledge. One emerging approach to constructing such repositories is proactive knowledge collection from large numbers of volunteer contributors. In this paper, we study the coverage and quality of a representative collection of part-of information contributed by volunteers. We analyze growth of cover...

Multi-threaded programs have many applications which are widely used such as operating systems. Analyzing multi-threaded programs differs from sequential ones; the main feature is that many threads execute at the same time. The effect of all other running threads must be taken in account. Partial redundancy elimination is among the most powerful compiler optimizations: it performs loop-invarian...

quantum-dot cellular automata (qca) is an emerging and promising technology that provides significant improvements over cmos. recently qca has been advocated as an applicant for implementing reversible circuits. however qca, like other nanotechnologies, suffers from a high fault rate. the main purpose of this paper is to develop a fault tolerant model of qca circuits by redundancy in hardware a...

The reported study was aimed at developing effective techniques for reducing learner cognitive overload while using pinyin (a phonetic system) to learn Chinese language. Learning effects of two instructional conditions (character-pinyin-pronunciation and character-pronunciation) were compared for learners with different levels of prior Mandarin proficiency and pinyin knowledge. It was expected ...

This paper presents a retrospective case control study of the General Practice consultation rates of 58 soldiers made voluntarily redundant. The redundees were compared over 140 days prior to the announcements of redundancy and 140 days after the announcements. No difference in consultation rates was found between the groups suggesting that voluntary redundancy in the Army has no effect on heal...

This contribution1 details a new OFDM modulator based on the use of a Pseudo Random Postfix (PRP-OFDM) and low complexity equalization architectures. The main advantage of this new modulation scheme is the ability to estimate and track the channel variations blindly using order one statistics of the received signal. This scheme is thus very well suited in presence of large Doppler spreads where...
