A practical three-dimensional shape optimization for aerodynamic design of a transonic wing has been performed using Evolutionary Algorithms (EAs). Because EAs coupled with aerodynamic function evaluations require enormous computational time, Numerical Wind Tunnel (NWT) located at National Aerospace Laboratory in Japan has been utilized based on the simple master-slave concept. Parallel process...

Traac equilibrium analyses are generally very large and computationally intensive. Parallel processing provides the memory and computational power needed to solve the equilibrium problems in a reasonable amount of time. Because the shortest path solution is the major component of these equilibrium algorithms, we focus on developing an eecient parallel algorithm to solve this problem. We investi...

BACKGROUND Urinary and (peripheral and central) intravenous catheters are widely used in hospitalized patients. However, up to 56% of the catheters do not have an appropriate indication and some serious complications with the use of these catheters can occur. The main objective of our quality improvement project is to reduce the use of catheters without an appropriate indication by 25-50%, and ...

This commentary considers the vexed question of whether or not we should be spending time and resources on using multifaceted interventions to undertake implementation of evidence in healthcare. A review of systematic reviews has suggested that simple interventions may be just as effective as those taking a multifaceted approach. Taking cognisance of the Promoting Action on Research Implementat...

This paper presents a novel adaptive reference governor for robust tracking control in constrained linear systems with bounded disturbances. The proposed reference governor achieves a performance improvement over the existing reference governors by virtue of its added feature: adaptability. The design of such an adaptive reference governor involves a nonlinear non-deterministic polynomial time ...

We consider the problem of recovering from failures of distributable threads with assured timeliness in dynamic systems with overloads, and node and (permanent/transient) network failures. When a distributable thread encounters a failure that prevents its timely execution, the thread must be terminated. Thread termination involves detecting and aborting thread orphans, and delivering exceptions...

Many computing tasks involve heavy mathematical calculations, or analyzing large amounts of data. These operations can take a long time to complete using only one computer. Networks such as the Internet provide many computers with the ability to communicate with each other. Parallel or distributed computing takes advantage of these networked computers by arranging them to work together on a pro...

Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...
