In recent years, the number of shipping containers grows rapidly, and in many container yard terminals, increasing throughput of material handling operation becomes important issue as well as decreasing the turnaround times of vessels. Material handling operations for loading containers into a vessel is highly complex, and the complexity grows at an exponential rate according to the growth of t...

The Axial Separation Module (ASM), which separates whole-blood specimens serially in Axial Process Containers (APC), was evaluated for clinical performance at the University of Virginia Health Sciences Center (UVA HSC) in a community-based outpatient laboratory (North Ridge Clinic). We hypothesized that moving the task of blood separation to point of care would reduce specimen turnaround time w...

We investigate a spherical collapse model with and without the spatial curvature. We obtain the exact solutions of dynamical quantities such as the ratio of the scale factor to its value at the turnaround epoch (x ≡ a ata ) and the ratio of the overdensity radius to its value at the turnaround time (y ≡ R Rta ) with general cosmological parameters. The exact solutions of the overdensity at the ...

In Round-Robin Scheduling, the time quantum is fixed and processes are scheduled such that no process uses CPU time more than one time quantum in one go. If time quantum is too large, the response time of the processes will not be tolerated in an interactive environment. If the time quantum is too small, unnecessary frequent context switch may occur. Consequently, overheads result in fewer thro...

Abstract Quay cranes are among the most important resources in port terminals, and their efficient use is crucial for terminals to remain competitive market. The problem of determining sequence tasks performed by quay that minimizes turnaround time a vessel an NP‐hard known as crane scheduling (QCSP). In this paper, we consider unidirectional QCSP under uncertain processing times, where only al...

OBJECTIVES The relative merits of hub and spoke models of service delivery are often debated, but accessing data on how they may benefit service delivery can be difficult, and may hinder the adoption of a model which can benefit the health community. Our aim was to provide objective data that would either support or refute one potential benefit of service redesign, namely the effect on turnarou...
