Due to increasing energy costs there is a need for accurate management and planning of shop floor machine processes. This would entail identifying the different operation modes of production machines. The goal for industry is to provide energy monitors for all machines in factories. In addition, where they have been deployed, analysis is limited to aggregating data for subsequent processing lat...

a two server queueing system with single and batch service is considered in this paper. the arrival process is assumed to be poisson and the service rate follows an exponential distribution. server-i serves the customers in both single and batch service, while server-ii serves the customers in batch service only. the laplace transform of the transient and steady state behavior of the model is c...

a number of innocent rashes occurs in neonates. they are usually transient and self limited and thus require no therapy but early recognition is important to distinguish these lesions from more serious disorders. in this study, our purpose was to determine the frequency of birthmarks in iranian neonates. the presence of various types of birthmarks was determined in 503 iranian neonates under 72...

heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. a heat transfer and solidification model is described for the continuous casting of steel slabs. the model has been established on the basis of the technical conditions of the slab caster in the continuou...

Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...

Conventional analysis techniques of queueing systems typically assume that the stochastic process under study is already in steady state. This assumption is, however, not valid if the life cycle of the process is not large enough. Previous work in transient analysis of queueing systems usually focuses on Markov models. This paper, in contrast, presents an analysis technique for investigating tr...

our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...

background primary congenital hypothyroidism (ch) is the most common treatable cause of mental retardation and can be classified into permanent and transient types. the purpose of this study was to determine the prevalence of permanent and transient congenital hypothyroidism (ch) in hamadan, west province of iran. methods the study population included all cases with primary congenital hypothyro...
