This paper represents linkage network of queues consisting of biserial and parallel servers linked to a common server in series with a flowshop scheduling system consisting of two machines. The significant transportation time of the jobs from one machine to another is also considered. Further, the completion time of jobs/customers (waiting time + service time) in the queue network is the set...

Background: In intensity modulated radiation therapy, cone beam computed tomography (CT) has been used to evaluate patients prior to treatment. This study conducted a comparative evaluation of the image reconstruction ability of the clinically used half-fan bowtie filter and the full-fan bowtie filter. Materals and Methods: A CT simulation marker was inserted inside a human phantom, and the pel...

In this paper, we consider the M/G/k queueing system with setup times. This particular queueing model is common in manufacturing systems, where idle machines are turned off to save on operating costs, as well as in server farms, where idle servers are turned off to conserve power. While recent literature has analyzed the M/M/k system with exponential setup times, no closedform solutions were ob...

<span lang="EN-US">This paper presents an energy management system with multiple sources. The proton exchange membrane fuel cell as the main power drive source is used when needed. However, because of its slow rate it combined a battery and supercapacitor racks secondary proposed conversion ensures demand electric vehicle. storage system, which includes supercapacitor, provides high level...

Body temperature affects outcomes of tissue injury. We hypothesized that online body core temperature recording and selective interventions help to standardize peri-interventional temperature control and the reliability of outcomes in experimental renal ischemia reperfusion injury (IRI). We recorded core temperature in up to seven mice in parallel using a Thermes USB recorder and ret-3-iso rect...
