In the standard frailty model the hazard function i s taken to be proportional to an unobserved random effect, specific to the individual. These frailties are the n taken to be independent realisations from a proba bility distribution of assumed form, and they are integrat ed out to form the likelihood function for the obse rved failure time data. In real applications the assumed istrib ution f...

We develop the use of piecewise linear test functions for the analysis of sta bility of multiclass queueing networks and their associated uid limit models It is found that if an associated LP admits a positive solution then a Lyapunov function exists This implies that the uid limit model is stable and hence that the network model is positive Harris recurrent with a nite polynomial moment Also i...

Broadcasting provides an e cient means for disseminating information in both wired and wireless setting In this pa per we study di erent client side cache organizations for various types of multiversion data broadcast i e data broad cast in which more than one value is broadcast per data item Besides increasing the concurrency of client transac tions multiversion broadcast provides clients with...

The Effect of Hyperbaric Oxygen on the Mental and Verbal A bility of Stroke Patients • Based upon the assumption that oxygen under increased atmospheric pressure (OHP) might improve the verbal and mental function of patients who had suffered vascular infarcts, 32 stroke patients were exposed to such an ambient atmosphere and tested under controlled conditions. The results make it clear that a s...

A new parallel hybrid method for solving the satissa-bility problem that combines cellular genetic algorithms and the random walk (W SAT) strategy of GSAT is presented. The method, called CGWSAT, uses a cellular genetic algorithm to perform a global search on a random initial population of candidate solutions and a local selective generation of new strings. Global search is specialized in local...

The Silicon Photomultipliers (SiPMs) are the new step in the development of the mod‐ ern detection structures in the area of low photon flux detection with a unique capa‐ bility of detection up to the single photons. The Silicon Photomultiplier intrinsically represents a digital signal source on the elementary cell level. The materials and tech‐ nology of SiPMs are consistent with the modern el...

| In this paper, we proposed a video coding technique which adopts motion estimation and compensation with temporal layering to provide temporal scala-bility. In this proposed video coding scheme, motion estimation is performed over temporal hierarchy of frames. Various motion estimation intervals of diierent layers lead to storage of multiple frames as references. These multiple references are...

We present three alternative simple constructions of small proba.­ bility spaces on n bits for which any k bits are almost independent. The number of bits used to specify a point in the sample space is (2 +o(l»(loglog n + log k + log ~), where f is the statistical difference between the distribution induced on any k bit locations and the uni­ form distribution. This is asymptotically comparable...
