We study the mean turnaround time of a Brownian needle in a narrow planar strip. When the needle is only slightly shorter than the width of the strip, the computation becomes a nonstandard narrow escape problem. We develop a boundary layer method, based on a conformal mapping of cusplike narrow straits, to obtain an explicit asymptotic approximation to the mean turnaround time. Our result sugge...

In this paper, we have proposed a new variant of Round Robin scheduling algorithm by executing the processes according to the new calculated Fit Factor ‘f’ and using the concept of dynamic time quantum. We have compared the performance of our proposed Fittest Job First Dynamic Round Robin(FJFDRR) algorithm with the Priority Based Static Round Robin(PBSRR) algorithm. Experimental results show th...

Learning curves have been described for different health technologies, mainly new surgical or diagnostic procedures, but learning curves for a new hospital's laboratory procedures have not been systematically studied. To monitor the timeliness (turnaround time) of stat tests from the Emergency Department as a marker of laboratory quality and to address the issue of a learning curve for procedur...

Institutional desktop grids, that is, grids comprised by the desktop machines of an institution (academic or corporate) can act as an important source of computing power for local user, if the high volatility of such resources is properly harnessed. In this paper, we focus on scheduling techniques that can improve turnaround time of bagof-tasks applications. For that purpose, we combine shared-...

The ground-level ozone is a pervasive air pollutant, which can be potentially elevated by flaring emissions during chemical plant turnaround operations (i.e., startup and shutdown). Especially in chemical plant concentrated regions, the regional air-quality (i.e., the ozone concentration) may be aggravated by simultaneous turnaround emissions from multiple chemical plants. Thus, under viable ma...

Test turnaround times are often monitored on a monthly basis. However, such an interval usually means that not all causes for delay in test reporting can be unequivocally identified for institution of remedial action. We have devised a daily chart--the freckle plot--that graphically displays the test turnaround times by laboratory receipt time. Different symbols are used to designate specimens ...

RATIONALE AND OBJECTIVES To compare resident workload from Emergency Department (ED) studies before and after the implementation of a required 1-hour report turnaround time (TAT) and to assess resident and faculty perception of TAT on resident education. MATERIALS AND METHODS Resident study volume will be compared for 3 years before and 1 year after the implementation of a required 1-hour TAT...

Hyper Text Transfer Protocol (HTTP) is a transfer protocol used by the World Wide Web distributed hypermedia system to retrieve objects. HTTP is a connection-oriented protocol which uses TCP (Transmission Control Protocol) as the transport layer protocol. HTTP does not interact very well with TCP. In this paper, we study the factors that affect the performance of HTTP over TCP and the transacti...
