The national QA system in Sweden does not any longer include assessment of the institutions’ internal QA procedures. The Experts Group on Quality at the Swedish Association for Higher Education (SHUF) has proposed and tested how voluntary audits can be performed by the institutions in collaboration, coordinated by SUHF. The audits have quality enhancement as its sole purpose. The audit method focu

This paper provides a general framework for electromagnetic modeling, computation and measurements regarding the wave propagation characteristics of High-Voltage Direct Current (HVDC) power cables. The modeling is focused on very long (10 km or more) HVDC power cables and the relevant frequency range is therefore in the low-frequency regime of about 0-100 kHz. An exact dispersion relation is form

Background: Presumed effects of global warming on occupational heat stress aggravate conditions in many parts of the world, in particular in developing countries. In order to assess and evaluate conditions, heat stress must be described correctly and measured correctly. Objective: Assessment of heat stress using internationally recognized methods. Design: Two such methods are wet bulb globe temper

This paper presents a constructive algorithm for memory-aware task assignment and scheduling, which is a part of the prototype system MATAS. The algorithm is well suited for image and video processing applications which have hard memory constraints as well as constraints on cost, execution time, and resource usage. Our algorithm takes into account code and data memory constraints together with the

To overcome the bottleneck of the one-way translation from VR (virtual reality) to CAD in VR-based CAD system, this paper proposes a Web-based VR-CAD system WVCD (Web-based virtual conceptual designer) to support both customers’ and design team members' involvement in the conceptual design and analysis activity over the Internet. It provides users with both parametric and freehand methods to creat

Traditionally humanitarian organisations have based warehouse locations on individuals’ experience and knowledge, rather than decision support tools such as network optimisation models. This paper presents a study undertaken for UNHCR aiming to develop an applicable warehouse location support tool by considering the most relevant contextual factors.

Popular Abstract in Swedish Avhandlingen beskriver en ny typ av kompakt röntgenkälla baserad på ett laser-producerat plasma (LPP). I motsats till konventionella LPP används inte fasta material som strålmål för den fokuserade laserstrålen. I stället används mikroskopiska vätskedroppar eller vätskestrålar. Detta medför en mycket väsentlig minskning av det skräp (debris) som skickas ut från plasmat. A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. The minute amounts of residual ionic/atomic debris can be obstructed by filters or a localized gas shield. Target liquid

In multiple-access communication systems co-channel interference can be mitigated by applying multiuser detection instead of treating the interference as additive noise [1]. In this paper we focus on downlink operation in a GSM-like TDMA network and investigate multiuser channel estimation and data symbol detection of two users that share the same physical channel in two adjacent cells. Such a sce
