P.043 Presence of infiltrative glioblastoma cells in an isolated area of diffusion restriction

Isolated diffusion restriction precedes the development of enhancing tumor in a subset of patients with glioblastoma.

BACKGROUND AND PURPOSE Most response criteria for patients with glioblastoma rely on increases in the contrast enhancing abnormality to determine tumor progression. Our aim was to determine retrospectively in patients with glioblastoma whether diffusion restriction can predict the development of new enhancing mass lesions. MATERIALS AND METHODS We reviewed the brain MR imaging scans (includin...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
