Caches do not grow in size at the speed of main memory or raw processor performance. Therefore, optimal use of the limited cache resources is of paramount importance to obtain a good system performance. Instead of a recency-based replacement policy (such as, e.g., LRU), we can also make use of a locality-based policy, based on the temporal reuse of data. These replacement policies have usually ...

Replacement and Insertion policies play a key part in determining the effectiveness of caching in both uni-processor and multi-processor systems. General strategies have been designed to take advantage of the principle of locality obeyed by a large class of computer programs-Temporal Locality and Spatial Locality. On this note, the LRU replacement policy and its variations have been the de-fact...

This paper explores a reliability based heuristic mathematical model for basic and classical age replacement policy. Using new model, optimal preventive age replacement policy is determined to maximize system reliability. For special systems having exponential density function with constant hazard function, a different simple decision-making model is proposed. A case study of two industrial mac...

Complete atrioventricular (AV) block is defined as a dissociation of atrial and ventricular activities. Complete AV block that occurs during the perioperative period is difficult to reverse and usually requires implantation of a pacemaker. Propofol does not affect a normal AV conduction system but may act as a trigger for AV block. It can also potentiate vagal stimulation factors and reduce sym...

This paper proposes an opportunistic maintenance policy for the multi-unit series production system. This proposed maintenance policy is on the basis of the failure rate analysis, which is more realistic than age-based or time-based opportunistic replacement models. When a system halts for performing preventive maintenance or opportunistic maintenance, the alternative decision of replacement an...

As the performance gap between memory and processors has increased, then it leads to the poor performance. Efficient virtual memory can overcome this problem. And the efficiency of virtual memory depends on the replacement policy used for cache. In this paper, our algorithm not only based on the time to last access and frequency index but, we also consider the power consumption. We show that Lo...

in order to study of use advantage in the intercropping system fennel (foeniculum vulgare mill) and fenugreek (trigonella foenum-graecum l) in different ratios of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the research station of faculty of agriculture, universi...

the application of equiframe in the analysis of sexual and reproductive health policies by ivanova et al to a new thematic area, their selection of only some of the core concepts of human rights in health service provision and the addition of new vulnerable groups relevant to the purpose of their analysis, are all very welcome developments. we also applaud their application of equiframe to poli...
