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.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Sambandet mellan personlighet och arbetssökande beteende har mestadels undersökts bland studenter tidigare. Denna studie undersökte om känslomässig instabilitet påverkade sättet att söka arbete hos 123 arbetssökande icke-studenter mellan 20-65 år. Enkäten som användes bestod av Personality Questionnaire (Bäccman & Carlstedt, 2010), som mäter personligheten utifrån femfaktorsmodellen, samt Job Search Behavior (Blau, 1994), som mäter förberedande och aktiva arbetssökande beteenden. Det fanns ett samband mellan känslomässig instabilitet och båda arbetssökande beteenden. Känslomässig instabilitet kunde dock inte ensam predicera vilket arbetssökande beteende individer väljer, men tillsammans med ålder kunde känslomässig instabilitet predicera förberedande arbetssökande, och ålder kunde även ensamt predicera förberedande arbetssökande.

When in the process of buying a product based high effort behavior, the consumer needs information to decide on which product that best satisfies their need. There is a wide arrange of sources where this could be found. One of the most important, due to the great influence it has on consumer choice, is in-store communications. This is also one of the least developed sources. It is not uncommon that the only facts that can be acquired are found on product packaging and from contact with the store´s staff.

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.

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.
