certificateless public key cryptography (cl-pkc) is a useful method in order to solve the problems of traditional public key infrastructure (i. e. large amount of computation, storage and communication cost for managing certificates) and id-based public key cryptography (i. e. key escrow problem), simultaneously. a signcryption scheme is an important primitive in cryptographic protocols which p...

This paper investigates the problem of optimal priority assignment in multiprocessor real-time systems using global fixed task-priority pre-emptive scheduling. Previous work in this area showed that arguably the most effective pseudo-polynomial schedulability tests for global fixed priority pre-emptive scheduling, based on response time analysis, are not compatible with Audsley’s Optimal Priori...

This paper examines the relative effectiveness of fixed priority pre-emptive scheduling in a uniprocessor system, compared to an optimal algorithm such as Earliest Deadline First (EDF). The quantitative metric used in this comparison is the processor speedup factor, defined as the factor by which processor speed needs to increase to ensure that any taskset that is schedulable according to an op...

Many industrial processes are in cascade configuration in which the material being processed goes through a sequence of processing units. The output of an upstream processing unit is fed into the input of the unit downstream. In many cases, the variables of interests are only available via related uncertain surrogate measurements in the all the upstream stages , and directly measured at the out...

Pre-emptive pharmacogenetic (PGx) testing combined with clinical decision support is a promising new strategy for making pharmacotherapy safer and more effective. To estimate the number of patients whose therapies could be guided by this approach, we analysed claims data for patients in Austria in the years 2006 and 2007. We calculated the number of patients receiving one or several drugs for w...

most of the patients imagine that chest pain is not sign of heart attack. but, may be pain is not sign of heart attack. pain source may be from pulmonary, stomach, intestinal, psychologic or musculoskeletal problems. from these factors, when two or more factors combine to each other, similar signs are happen. all of these factors harden diagnosis of chest pain reason. only with separation of pe...

 Statins are commonly used drugs in the treatment of hyperlipidemia (HL), despite some undesirable side effects. These range from mild symptoms such as myopathy, muscle weakness and myalgia to severe muscle weakness associated with chronic myopathy and acute renal failure (ARF) as a result of rhabdomyolysis. The most serious and deadly side effect of statins is rhabdomyolysis. The case presente...

There is a flood of papers being published on new ways to diagnose Alzheimer disease (AD) before it is symptomatic, involving a combination of invasive tests (eg, spinal tap), and pen and paper tests. This changes the landscape with respect to genetic tests for risk of AD, making rational suicide a much more feasible option. Before the availability of these presymptomatic tests, even someone wi...
