ÐReal-time systems are being increasingly used in several applications which are time-critical in nature. Fault tolerance is an essential requirement of such systems, due to the catastrophic consequences of not tolerating faults. In this paper, we study a scheme that guarantees the timely recovery from multiple faults within hard real-time constraints in(More)
Many real-time multiprocessor scheduling techniques have been proposed to guarantee the timely execution of periodic preemptive real-time tasks. However, timeliness is usually only guaranteed in the absence of faults, which may be unacceptable for some critical systems. We therefore address the problem of multiprocessor scheduling for preemptive real-time(More)
Embedded systems serve an emerging and diverse set of applications. As a result, more computational and storage capabilities are added to accommodate ever more demanding applications. Unfortunately, adding more resources typically comes on the expense of higher energy costs. New chip design with Multiple Clock Domains (MCD) opens the opportunity for(More)
We investigate methods of generating additional bilingual phrase pairs for a phrasebased decoder by translating short sequences of source text. Because our translation task is more constrained, we can use a model that employs more linguistically rich features than a traditional decoder. We have implemented an example of this approach. Experimental results(More)
The purpose of the present study was to observe the casual levels of volatile sulphur compounds (VSC) in volunteers with different clinical scores of tongue coating, periodontal pockets depth and Gingival Bleeding Index. Seventy-two subjects who attended for the first time at the dental clinic of the University were randomly selected for intra-oral and(More)
This paper investigates the idea of adapting language models for phrases that have poor translation quality. We apply a selective adaptation criterion which uses a classifier to locate the most difficult phrase of each source language sentence. A special adapted language model is constructed for the highlighted phrase. Our adaptation heuristic uses lexical(More)
