Resemagasinens paradoxala verklighet : En studie om webbaserade resemagasin
The purpose of this study has been to examine online travel magazines as an information source and as a virtual service scape. The traditional travel magazines are facing a change due to the technological development and the web has become an important platform for both customers and companies. The virtual service scape opens new opportunities for interaction and we found a great interest in examining which possibilities and limitations travel magazines are facing. This study is based on a qualitative approach because we wanted to gain a deeper understanding and a complete picture of our chosen subject. We have completed six interviews; three of them were consultants, one publishing director, one editor and a research student.
Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
State of the Arts in Virtual Worlds
Virtuella världar kan vara så mycket mer än bara spel vilket jag går igenom. Frågan är då vad mer är det och till vad kan de användas? Genom studier och genomgångar av vetenskapliga visar vart det virtuella användandet står idag och till vad virtuella världar kan användas. Jag försöker också ge svar på om det bör vidareutvecklas och användas mer. Det jag går in på är bland annat virtuella obduktioner.
Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment
This study examines the use of building modeling and energy simulations in the design process of a building. The take-off point is the notion of energy simulations being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines, such as the architect and the energy specialist, would create smoother workflows, which would reduce this cost and open up for more frequent and iterative energy simulation processes. The study is an assessment of the modeling tool Revit and the simulation tool Virtual Environment and whether they can create smoother workflows, and make leeway for a more frequent use of energy simulations throughout the design process. It also investigates the limitations of what can be examined by simulations in Virtual Environment. This will hopefully help clarify the future role of energy simulations in design processes. The method is a trial by error approach of testing the two software tools by building and simulating a model. The results of these tests show that the workflow is not optimal (and therefore time consuming) for frequent and iterative simulations throughout the design process, but it also reveals some great possibilities of what can be performed with these two powerful tools at hand. Further development with regards on platform independency of the building information model, including seamless exporting and importing, seems necessary to strengthen the future role of energy simulations..
Kriminalitet sätter mannen på prov ? En studie av identitetsskapande i romanen Snabba Cash.
The aim of this Master?s thesis is to examine how representations of identity construction are performed through the characters in the novel Snabba Cash by author Jens Lapidus. I examine what means the characters are using, and how the identity construction processes are related to the idea of modern society. For a theoretical background I use sociologist Anthony Giddens? theories regarding modernity and self-identity, to study general identity construction.
Kan Virtual Routing and Forwarding stoppa en datamask från att sprida sig mellan två nätverk?
Med denna uppsats vill jag undersöka om Virtual Routing and Forwarding (VRF) kan förhindra spridningen av datamasken Blaster mellan två kunders nätverk. Ämnet VRF valdes för att det finns ett personligt intresse och för att det är en viktig säkerhetsfunktion i ett större nätverk.För att undersöka detta genomförde jag två tester, en utan VRF och en med VRF. Datamasken aktiverades i båda testerna och spridningen analyserades med programvaran Wireshark.Testen visade att VRF segmenterar nätverken på ett sådant sätt att Blaster inte kan sprida sig mellan två nätverk som är segmenterade med VRF..
Är tiden inne för virtual reality i hemmet? - En experimentell studie av virtual reality med 3D och head tracking
Genom åren har intresset för och satsningar på underhållning i tredimensionellt format (3D) gått i vågor. Idag har de flesta biografer stöd för att visa 3D-filmer. Utöver detta intresse har det på senare år även börjat komma mer teknik för 3D i hemmet. Det har också introducerats många nya mer immersiva och intuitiva inmatnings-enheter som bidrar till under-hållning med element av virtual reality hemma. Företagen Sony, Nintendo och Microsoft har alla lanserat olika typer av avancerade tekniker för sådana inmatnings-enheter till sina spel-system.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Äldre och teknologiska hjälpmedel : interaktionsmönster som metod för att studera hur teknik i framtiden kan användas inom äldreomsorgen.
Ny teknologi har skapat nya möjligheter inom utvecklingen av teknologi för äldre. Kunskap behövs om de äldres behov och vilka situationer i vardagen som skulle kunna underlättas av teknik för att minska de äldres beroende av andra människor. I utvecklingen av ett interaktivt teknologiskt hjälpmedel en så kallad virtual companion har en etnografisk studie gjorts för att kartlägga vardagen på ett äldreboende och interaktionen mellan vårdgivare och vårdtagare. Dessa har strukturerats upp i interaktionsmönster för att bli ett underlag till funktioner som skall implementeras i hjälpmedlet..
L?gkonjukturens p?verkan inom byggf?retag
The purpose of this study was to gain a better understanding of how medium-sized construction companies adapt and how they choose to reorganize their operations in relation to the recession. The study has as its theoretical starting point theories about organizational learning, the impact of the economy on construction companies and strategies for dealing with recessions. The
method used to conduct the study was semi-structured interviews with representatives from 15 different construction companies. The results of the study show that they used several strategies to adapt and reorganize the business in accordance with the recession. Some construction companies had to make cost savings as a result of the recession.
Vädrets påverkan på byggarbetsplatsen
This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.
Värdering av anbud vid kommunala upphandlingar av byggprojekt
The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.

Ägarstrukturen i Sverige : Hur påverkar den företagens resultat?
Frågan om verkligheten och dess beskaffenhet har länge orsakat stor förbryllning hos människan, vilken historiskt sett har försökt förklarats på olika sätt. Inte minst genom olika slags gudaläror. Idag lever vi helt annorlunda än vad vi gjorde för exempelvis 1000 år sedan. Det är inte längre gudar som är den dominerande verkligheten ? det är IT-tekniken.
Industrialiserat byggande : Fältfabrikens användning, utveckling och framtid
The construction industry is currently receiving much criticism for inefficiency and slow development while demands for reduced built in moisture and efficiency increases. This report examines whether the use of field factories can meet these requirements and what factors that will be critical for future use of field factories. Industrialized construction with field factory is compared with traditional loose timber construction and industrial construction in the fields of execution, logistics and working environment. The aim of this report is to provide a basis for field factories current and future use and development. To achieve the aim of the report, people with experience in the use of the various methods was interviewed and literature studies in the various fields done.
