Dynamic Evaluation of the Overloading Potential of a Convection Cooled Permanent Magnet Synchronous Motor

In order to obtain the maximum efficiency from a hybrid driveline it is crucial to optimize the power distribution between the electric drive and the internal combustion engine. An accurate estimation of how much electric power can be delivered at any instant of time is therefore of great interest. Such estimation is dependent on several factors, as the state of charge of the battery, the temperat

Indentation of thin copper film using peridynamics

The rapid development of the technology of today increasingly involves the design and fabrication of devices of smaller and smaller dimensions, down to the atomic length scales. At the nanoscale molecular dynamic (MD) models are often used. For many but the smallest systems, MD models are computationally too expensive, whereas classical continuum mechanics models not accurately can resolve microsc

Estimation of Spherical Wave Coefficients from 3D Positioner Channel Measurements

Electromagnetic vector spherical waves have been used recently to model antenna channel interaction and the available degrees of freedom in MIMO systems. However, there are no previous accounts of a method to estimate spherical wave coefficients from channel measurements. One approach, using a 3D positioner, is presented in this letter, both in theory and practice. Measurement results are present

Distributed resource management using iterative gradient update synthesis

We consider load balancing on a network. Servers of limited bandwidth move a single commodity through a network of buffers (or queues) while external random processes generate and consume this commodity. Our contribution is a distributed algorithm for regulating the backlogs of these queues to a given reference while balancing the mean flow in the network. We formulate this as a fluid buffer regu
