We propose an adaptive cache coherence-replacement scheme for web proxy cache systems that is based on several criteria about the system and applications, with the objective of optimizing the distributed cache system performance. Our coherence-replacement scheme assigns a replacement priority value to each cache block according to a set of criteria to decide which block to remove. The goal is t...

E-type software, software implementing real world computer applications, must be continually evolved to maintain user satisfaction, generally over several years and releases. It is likely that the responsible organisation will, sooner or later, consider its replacement through redevelopment or acquisition. This paper discusses elements believed to be relevant in the context of replacement decis...

OBJECTIVE To evaluate the prognostic value of platelet counts in acute kidney injury patients requiring renal replacement therapy. METHODS This prospective cohort study was performed in three tertiary-care hospitals. Platelet counts were obtained upon admission to the intensive care unit and during the first week of renal replacement therapy on days 1, 3, 5 and 7. The outcome of interest was ...

Adoption of a new technology in surgery today is subject to assessment by many stakeholders. These include surgeons, patients, hospitals, regulators, and payers. The fundamental tool for assessment is the determination of “value.” But value has different meanings for each of the stakeholders.The usual definition of value is “outcomedivided by cost.”Although cost is usually measured in dollars, ...

Ochronosis or black joints disorder is a rare autosomal recessive disorder caused by deficiency of homogentisic acidoxidase. Orthopaedic manifestations are common and mostly involve spine and large joints such as knee and hip.Arthropathy is progressive and will eventually leads to arthroplasty. Not being familiar with this disorder might lead todevastating complications. We present a 57 year-ol...

Fuzzy set has been applied in many real applications to handle uncertainty. The aim of the paper is to study the replacement problem with uncertainty. This problem involves capital cost, scrap value or salvage value, maintenance cost or operating cost, and rate of interest having an imprecise value. Here, we assume the imprecise values as positive trapezoidal fuzzy numbers. Moreover, we conside...

In this work we propose a cache memory system based on an adaptive cache replacement scheme, as part of the virtual memory system of an operating system. We use a sequential discrete-event simulator of a distributed system to compare our approach with previous work. Our adaptive cache replacement scheme is based on several criteria about the system and applications with the objective being to e...

We propose an adaptive cache coherence-replacement scheme for distributed systems that is based on several criteria about the system and applications, with the objective of optimizing the distributed cache system performance. We examine different distributed platforms (shared memory systems, distributed memory systems, and web proxy cache systems) and the potential of incorporating coherency-re...

-The simple replacement technique of cement by fly ash in concrete does not produce a concrete with desirable early strength which is a significant parameter of present day emphasis of speedier construction. Increasing the amount of flyash replacement slows down the strength development at early ages. For effective mix proportioning of fly ash concrete, cementing efficiency factor has to be tak...
