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

The time-difference of arrival techniques are adapted to locate networked enemy radars using a cooperative team of unmanned aerial vehicles. The team is engaged in deceiving the radars, which limits where they can fly and requires accurate radar positions to be known. Two time-differences of radar pulse arrivals at two vehicle pairs are used to localize one of the radars. An explicit solution for

People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application for Android in which a user may scan for map information using the

Popular Abstract in Swedish Hur kan man skapa en tredimensionell modell av ett objekt eller en plats från tvådimensionella bilder? Det är den centrala frågan i den här avhandlingen och en viktig fråga i datorseende generellt. Normalt delar man upp problemet i en serie basproblem. Ett basproblem kan till exempel vara att skatta kamerans rörelse mellan två bilder eller kamerapositionen för en ny bilThis thesis is concerned with the geometrical parts of computer vision, or more precisely, with the three-dimensional geometry. The overall aim is to extract geometric information from a set of images. Most methods for estimating the geometry of multiple views rely on the existence of robust solvers for a set of basic problems. Such a basic problem can be estimating the relative orientation of two

The paper presents two recently developed, Matlab-based analysis tools for realtime control systems. The first tool, called Jitterbug, is used to compute a performance criterion for a control loop under various timing conditions. The tool makes it easy to quickly judge how sensitive a controller is to implementation effects such as slow sampling, delays, jitter, etc. The second tool, called TrueTi
