This paper describes a system that enables parallel programs written using the BSPlib communications library to migrate processes among a network of workstations. Not only does the system provide fault tolerance of BSPlib jobs, but by utilising a load manager that maintains an approximation of the global load of the system, it is possible to continually schedule the migration of BSP processes o...

The rugged mountainous regions of the deep seafloor hold both great scientific interest as well a host of difficult challenges for autonomous robots. Exploiting its abilities for precise navigation, trackline following, and bottom-following in rough terrain, the Autonomous Benthic Explorer (ABE) collected fine-scale bathymetry, magnetics, temperature, optical backscatter, and conductivity over ...

This article presents a review on the existing techniques for manipulating biological cells. Because biomanipulation involves a wide range of disciplines, from biology to engineering, we concentrate on some of the key methodologies that would result in an efficient biomanipulation system. Some of the key methodologies discussed in this article for cell manipulation relate to the use of magnetic...

In prior work a planar permanent magnet. (PM) configuration for generating an approxinlat~e quadrupole field distribut,ion in the vicinity of its symmetry axis was disclosed. In the present paper extensions of the inet,hod are considered for generat,ing sextupole and higher order multipole fields. The field distributions and strengt,hs are contrasted with idealized (azimuthally periodic) mulhip...

Most of the power factor regulator topologies in continuous conduction mode result in bulky magnetics, and in discontinuous conduction mode result in high harmonic content. To solve these problems a Cuk topology is presented in discontinuous conduction mode (DCM) with coupled inductors for power factor regulation, the unique feature exhibited by the converter that makes the converter better tha...

| In this paper design sensitivity analysis is applied to solve the TEAM workshop problem 25. In order to justify the use of a gradient method, it is necessary to assume a continuously di erentiable dependence of the sti ness matrix on the design parameters. Since design sensitivity analysis is mainly applicable to optimization problems, where the geometrical parameters undergo small changes on...

This paper presents an interleaved boost converter with integrated magnetics for common-mode (CM) noise reduction without introducing electromagnetic interference (EMI) filters. The is realized using the balanced technique, which effective CM technique from a circuit topology perspective. application of this addresses issue noise, while avoiding increase in volume due to EMI Additionally, and c...
