The simultaneous localization and mapping problem is approached by using an ultrasound sensor and wheel encoders. To be able to account for the low precision inherent in ultrasound sensors, the occupancy grid notion is extended. The extension takes into consideration with which angle the sensor is pointing, to compensate for the issue that an object is not necessarily detectable from all position

Conflicts between project stakeholders can stop or damage a construction project as well as technical problems. It is not uncommon that projects are stopped or changed late in the process with the effect that large amounts of already made investments becomes obsolete. One explanation of this phenomena is the escalation of project decisions, where project managers persist with a course of actions l

Abstract This paper aims to gain a better understanding of the impact different micro-geometries has on stress distribution in cutting tools. Both principal and effective stress distribution are studied since these quantities have a major impact on the occurrence of damages in the cutting tool such as crack formation, flaking, chipping, breakage and plastic deformation. The development of a stagna

This thesis takes as its point of departure an elective course in English: 'Drama in Practice - Shakespeare on Stage'. The course combines theory and practice in that it contains (on the one hand) lectures and written work about one of Shakespeare’s comedies, and (on the other hand) an on-stage part with rehearsals of the same play, culminating in a performance, in costume, before an audience. The

The aim of this thesis was mainly to find out the conditions under which a modernisation of the standardisation process could realistically take place, in order to allow the inclusion of parameters that are currently ignored. The necessary balance between private interests and public good issues, and the need to take into the discussions leading to the adoption of standards, their generally heavy

The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th

Healthcare organisations such as hospitals communicate both public and personal information to citizens. Accessible websites are suited for public information, but personal information (e.g. medical appointment notices) is still sent out by ordinary post in the form of text on a paper. Sometimes a person has to ask repeatedly for accessible information and is forced to adapt to the information sys

A list sequence (LS) maximum a posteriori probability (MAP) decoding algorithm for convolutional codes, that takes into account bitwise a priori probabilities and produces a rank ordered list of [script L] sequence MAP estimates, can be obtained by modification of the metric increments of the serial list Viterbi algorithm. In this paper, we study the performance of LS-MAP decoding with genie-assis

Pingviner finns bara på södra halvklotet. Idag finns 17 arter, varav du möter de allra flesta i den här boken. De minsta arterna håller till närmast ekvatorn, till exempel på Galapagos, de största arterna, som kejsarpingvinen, lever närmast Sydpolen på Antarktis. Fåglar brukar förknippas med förmågan att flyga. Pingvinerna är i stället extremt väl anpassade till ett liv i havet. På land känns de
