A Technique for Optimization of System-on-Chip Test Data Transportation

We propose a Tabu-search-based technique for time-constrained SOC (System-on-Chip) test data transportation. The technique makes use of the existing bus structure, where the advantage is, compared to adding dedicated test buses, that no additional routing is needed. In order to speed up the testing and to fulfill the time constraint, we introduce a buffer at each core, which in combination with di

A Semi-Lagrangian Method for a Fokker-Planck Equation Describing Fiber Dynamics

A simplified Fokker-Planck model for the lay-down of fibers on a conveyor belt in the production process of nonwovens is investigated. It takes into account the motion of the fiber under the influence of turbulence. The emphasis in this paper is on the development of a numerical procedure to solve the model. We present a semi-Lagrangian scheme that accurately captures the fiber dynamics and conser

Increased examination frequency and learning for a large group of students early in their education

Abstract—Denna artikel beskriver hur undervisningen i grundkursen i mekanik för maskinteknik förändrades för att främja djupinlärning hos studenterna och öka examinationsfrekvensen. Strategin var baserad på utökade möjligheter för aktiv inlärning och styrning av inlärning genom att införa förändringar i examinationen. Under kursens gång implementerades kontinuerlig examination med inlämningsuppgif

How much PAR to bring to the party?

Reducing Peak-to-Average power Ratios (PAR) is an established research topic that has now begun to find its way into products. This gives rise to new questions of dimensioning. Here we address how much PAR reduction that should be applied in a practical system. We demonstrate that the amount of PAR reduction can be found with the appropriate system models. This is applied to the tonereservation PA
