We analyze the Two Level Processor Sharing (TLPS) scheduling discipline with hyperexponential distribution for the job size and with Poisson arrival process. TLPS is a convenient model to represent the file size based differentiation in TCP/IP networks. We find a closed form analytic expression for the expected sojourn time and an approximation for the optimal value of the threshold that minimi...
background consumption of home-distilled alcohol may lead to epidemic or sporadic cases of severe acute methanol poisoning. the difficulty of establishing strict indications for hemodialysis in acute methanol poisoning is a widely recognized issue. materials and methods the determination of the clinical, especially hemodialysis, and para clinical factors influencing patient survival in 46 acute...
we compared the extent of temporary threshold shift (tts) and hair cell loss following high level 4 khz noise exposure with those preconditioned with moderate level 1 and 4 khz octave band noise. fifteen male albino guinea pigs (300- 350 g in weight) were randomly allocated into three groups: those exposed to 4 khz octave band noise at 102 db spl (group 1, n=5); those conditioned with 1 khz oct...
(t, n)-threshold secret sharing was first introduced by Shamir and Blakley separately in 1979. Apart from this, there are threshold secret sharing schemes which use the Chinese Remainder Theorem (CRT). The above mentioned are three of the most extensively researched tools used for designing a (t, n)-threshold secret sharing scheme. In this paper we propose a scheme for Multilevel Threshold Secr...
background and aim: human beings receive a variety of sounds in their everyday lives. these sounds are generated by different sources, and are heard simultaneously or with a small time sequence. a characteristic of the auditory system is its ability to analyze complex sounds, and to make decisions about the source of each constituent part of these sounds. the present study intends to assess nor...
Introduction: Nowadays, noise exposure is one of the most important industrial health problems. Noise exposure can cause hearing loss and many other health problems. So, paying attention to the noise exposure problem should be of main priority in industrial health programs. This study was conducted in an oil producing region, aimed to assess noise pollution and noise induced hearing loss. Met...
background : few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. the purpose of this study was to determine threshold levels of meningitis outbreak in hamadan province, west of iran . methods : data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 march 2010 to 20 march 2012 were use...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
