For most dog owners today it is natural to use acoustic stimuli such as talking to communicate with their pets. Words are used both to ask the dogs to perform tricks, as well as to hold ?conversations? with the dog. This literature review looks at how dogs perceive human acoustical communication and how this can influence the behaviour of the dog. This information could be used e.g.

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

Utifrån tidigare forskning om och utvärderingar av musikämnets ställning i lärarutbildningen är syftet med förestående uppsats att ytterligare belysa musikämnets situation i den svenska lärarutbildningen såsom den manifesterar sig i kursplanerna på högskolor och universitet. Föremål för analys är samtliga lärarutbildningars kursplaner i det allmänna utbildningsområdet (AUO), som tillsammans med den nationella kursplanen i musik (Kp2000) utgör underlag för besvarandet av forskningsfrågan ?På vilket sätt förbereds lärarstudenter för musikundervisning enligt Kp2000??. Ur ett hermeneutiskt perspektiv genomförs analysen baserad på fyra sökord; ?Musik?, ?Estetik?, ?Musisk? samt ?Konstnärlig?, ord hämtade ur den presenterade kontexten kring analysobjekten.

I Sverige genomförs varje år offentliga upphandlingar till ett värde av ca 500 miljarder kronor. Alla offentligt finansierade verksamheter måste följa lagen om offentlig upphandling och den formella upphandlingsprocess som lagen specificerar. Lagen är allmänt formulerad och anvisar en process där fokus ligger på förarbete och matematisk utvärdering.Cognitive Systems Engineering har vuxit fram utifrån insikten att effektiva processer kontinuerligt behöver använda såväl feedback och feedforward för att uppnå sina mål. Typiska tillämpningar är dynamiska, tätt kopplade processer där dessa behov är tydliga, men CSE som ramverk är generellt definierat och bör gälla även för en beslutsprocess på organisationsnivå. En CSE-analys har potential att förtydliga funktionella faktorer som tillåter upphandlare att genomföra effektiva och ändamålsenliga upphandlingar.I syftet att testa ovanstående hypotes genomfördes en fallstudie av Linköpings Universitets upphandling av företagshälsovård 2008.

This essay examines through a sociological perspective how physical objects in Ted Kooser?s poetry collection "Delights & Shadows" can be used to depict the characters? social environment. This is done by examining the physical objects found in 25 poems, the relationships between subjects and objects, and how this relationship can describe the social environment. The essay also examines how the relationship between subjects, objects, and the presence of the social environment within the text affects the reader experience. The physical objects are examined with Bill Brown?s Thing Theory as "things" that stop working for humans, when their flow within the circuits of production and distribution, consumption and exhibition is arrested, however momentarily.

This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

Detta examensarbete har utförts vid Duroc Engineering AB i Luleå. Duroc Engineering är Sveriges ledande företag inom laserförädling av metalliska ytor och levererar tjänster och produkter till framförallt gruv-, stål-, flyg- samt verkstadsindustrin. Rostervagnar transporterar kulor som används vid sintringen i Malmberget vid LKAB:s kulsinterverk. Genom att vagnarna passerar genom olika värmezoner sintras kulorna och vagnarna töms därefter för att hämta upp nya kulor. Detta pågår dygnet runt, året om, vilket medför stort slitage på vagnshjulen.

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

The purpose with this examination task is to investigate what purchasers and building contractors think of ISO 9000 and the function of it within the building trade.In this material both the purchaser´s and the building contractor´s viewpoints and attitude towards ISO 9000 is being object to an investigation, in order to get a just picture of the function of the quality work within the building trade. The general opinion of ISO 9000 has proven to be positive. During the work with this investigation it appeared that nosystem is that good that it can´t be improved. A widely spread opinion is also that ISO 9000 means a lot of paperwork but also that the certified companies are well organized. Above all the majority demands a standard that is more adjusted to the building trade..

Ett CRM system ger fördelar för ett företags förmåga att bygga varaktiga kundrelationer. Små och medelstora företag är dock tveksamma till att investera i sådana system. Resurserna för att dels investera i och sedan effektivt förvalta systemen fattas ofta i företagen. Implementationerna av systemen drar dessutom ofta ut på tiden. Modellen Software as a Service har under 2000 talet vunnit stora landvinningar.

In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.

VSEM project and the need for a more efficient way of handling requirements andinformation are highly apparent.The overall objective of this thesis is divided into two parts:1. To identify criteria/factors leading to a successful introduction of an informationmanagement system.2. To develop an implementation process for a requirement management system ?the first step towards a PLM system in EE development at VCC.This will be done through interviews with employees, a literature review and an analysisof studies of three earlier projects within VCC.The conclusion of this study shows the great need for change in work methods fordesigners handling information and requirements. An implementation process has beenidentified with guidelines on how to handle different phases of the process.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

The ?peer to peer? (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world.
