This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.

The purpose of this study was to evaluate Komm-A, a model for usingcommunication books in clinical practice for people with aphasia. The studyconsisted of two group studies and one case study. One of the group studies had apretest-posttest design and consisted of nine couples; a person with aphasia andhis/her communication partner. The material used was Quality of communicationlife scale (QCL), Communicative effectiveness index (CETI), Goal attainmentscaling (GAS), and a questionnaire to the communication partner. The other groupstudy consisted of seven speech-language pathologists who worked with thecouples according to the Komm-A model.

Three years after the Bosman case, it was decided that a socio-cultural approach on sports be introduced in Europe. EU presented a formulation for the same purpose ? The European Model of Sport. The purpose of this formula was to maintain the socio-culture and traditional ap¬proach to all kinds of amateur and professional sports in Europe. If we were to com¬pare this model with the American model of sport, it shows many different ways of thinking in terms of organised sport.

Ljungberg & Kögel AB är ett enmansföretag som specialiserat sig på blodprodukter för hela världsmarknaden. Idag har Ljungberg & Kögel ingen försäljning på den Amerikanska marknaden där det tappas 14.5 miljoner helblod varje år. Därför vill företaget undersöka möjligheterna att utveckla och lansera en ny blodvagga primärt avsedd för den amerikanska marknaden. I detta projekt har systematisk problemlösning används för att strukturera utvecklingen och dess faser. Projektet inleddes med informationsinsamling där konkurrentanalys, intervjuer och observationer gav en bas av kundbehov för produktutvecklingen.

Återtillverkning är ett koncept som får allt större betydelse inom dagens tillverkningsindustri. Konceptet bygger på att uttjänta produkter tas tillbaka och återfår ett marknadsvärde genom en process som innefattar: sortering, rengöring, demontering, bearbetning, montering och testning. Återtillverkning är mer vanlig i USA där metoden använts under många decennier, men mer ovanlig bland svenska företag. Detta är dock någonting som är på väg att förändras i och med hårdare lagstiftningar och en ökad miljömedvetenhet bland företagen.I syfte att föra ut kunskap och utforska metodikens för och nackdelar har Linköpings Tekniska Högskola startat ett projekt som går under namnet REKO. Detta examensarbete är det andra som ingår i projektet och är ett samarbete mellan högskolan och Scandi-Toner AB.

Ergotopia är ett nystartat företag vars ambition är att marknadsföra och sälja produkter av ergonomisk fördelaktig karaktär. Pilotprojektet, Komfort, är en ny typ av bäddprodukt som tagits fram i samarbete med Borås Textilhögskola. Komfort är utformad som en praktisk rulle och inkluderar bäddmadrass, underlakan, täcke och påslakan som enkelt kan rullas ut på sängmadrassen. Alla dessa delar har kombinerats ihop till två enheter, den ena fungerar som bäddlakan och den andra som täcke. Detta koncept har stora ergonomiska fördelar mot konventionellt bäddande.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

SammanfattningElectrolux är ett världsomspännande företag som producerar ett stort urval av produkter så somdiskmaskiner, kylskåp och dammsugare. En produktsort i Electrolux utbud är handhållnabatteridrivna dammsugare, vilka utgjorde 12 % av den sålda volymen dammsugare i Europa frånföretaget vid mätning i juni 2010. I Sverige har Electrolux en ledande position på marknaden förhandhållna batteridammsugare, men för att behålla försprånget krävs en ständig utveckling avnya, konsumentrelevanta produkter.Examensarbetet genomfördes under hösten och vintern 2010/2011 och hade som mål att ta framett till tre konsumentrelevanta koncept på handhållna batteridrivna dammsugare, vilka skullebygga på den nya tekniken borstlösa motorer. Resultatet presenteras i denna rapport, menlevererades också till Electrolux i form av fungerande prototyper.Projektet följde Electrolux utvecklingsprocess för primärutvecklingsprojekt vilket innefattadeförstudie, idégenerering, utvärdering, CAD-modellering och bygge av prototyper. Arbetetutfördes på Electrolux huvudkontor i Stockholm och omfattade 20 veckors arbete.I idégenereringsarbetet användes flera stödmetoder så som brainstorming, funktionsanalys ochmorfologisk matris och arbetet resulterade i fem olika koncept.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.
