Virtuell design av en testrigg för ett vindkraftverks drivlina - Analys av vibrationsdynamik
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.
Det sinnliga upplevandet av landskapet : en teoretisk undersökning av positiva emotioners roll vid utomhusrekreation
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.
Diagnostiksystem i gaffeltruckar
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.
Distributionsekonomisk optimering av dagligvaruhandelns lokalisering : förstudie till ett forskningsprojekt
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.
Mobilannonsering: Hur ett värdenätverk formas kring en ny mediekanal
Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.
Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet
General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
Geodatasamverkan - nyttan för en kommun att delta
The Swedish model for developing the national infrastructure is based on increasing the cooperation between municipalities, government and businesses. The method to establish the infrastructure in Sweden is the geodatastrategin. The effort to implement the geodatastrategin has resulted in an interaction model, Geodatasamverkan. The purpose of this study is to alert municipalities and to investigate the usefulness of their participation in Geodatasamverkan. The study also presents examples of different applications where geodata can be used within a municipality. The report is based on literature reviews, surveys and interviews. Online Surveys were sent to some of Sweden's municipalities to get an overall idea of ??how they make use of geodata and their general attitude towards Geodatasamverkan.
Att leta efter kännskap : Hur lärare ser på utemiljön som en miljö för lärande
In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.
Projektmodell för införande av affärssystem : Ett konsultbolags implementeringsprocess i tjänsteföretag
Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.
Ämnesordsindexering av ryttmästare John Andréns specialsamling : Utveckling av en indexeringsmodell utifrån teoretiska och praktiska perspektiv
This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.
"Det känns ganska fräscht att ha en Volvo för att nu har ju dom den i Solsidan" : En kvalitativ attitydundersökning om svenska tv-tittares attityd till produktplacering
Since product placement is a relatively new phenomenon in Swedish television, there is a lack of research on what attitudes Swedish TV-viewers hold towards it. This is where our paper will contribute to the research. The purpose of this reserachpaper is to describe and analyze what attitude Swedish TV-viewers has towards product placement. Kim Schröders multidimensional model of mass media reception were used, which is a developed model from Stuart Hall?s ?encoding/decoding? one-dimensional model.
En utvärderingsmodell för testverktyg : Med inriktning på automatiserade högnivåtester
Testing has always been an important task in the scope of software quality. Though it has never been as much appreciated within the management of the organisations as the software development has. However testing is becoming more attractive within organisations because it becomes more evident how much money working systems saves in contrast to defect ones. A tester often use testing tools to simplify the work progress. There are a lot of tools nowadays but not many evaluating models which helps the tester to know which one to recommend.
Empirisk studie av den radiella förspänningskraftens variation i klassiska skärskruvförband
In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.
Grönare konsumtion : Hur konsumerar deltagare i MiljöVarDag projektet idag?
The way we socialize today is radically different from how it was only twenty years ago. Since the arrival of the Internet more and more of what we know about the lives of our friends comes from text-based social networks, or blogs. This means that we all, more or less, have become authors of our own life stories and that the reality we live in have become fictionalized. In this paper I explore what effects this postmodern process of dissolving boundaries has had on the autobiographical genre, where the line between fiction and reality is traditionally stressed. By analysing Carina Rydberg?s (b.
Kunskap om marknaden : Besöksattraktioners vikt och dess relation till turistmålgrupp och resesyfte
The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.
