To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

The environmental work in Sweden has developed a lot over the past fifty years. Today, most companies have some kind of environmental work. Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.

The reason why this essay is written can be parted in two, whereas one would be the global trend of urbanization that occurs to this moment and forward, whereas the other would be the debate of how motorism has come to be an issue of sustainable management of our cities and our environment. In purpose to deliver a thorough understanding of how the car and its capacity has come to shape the society of today, and to emphasize the problems it´s brought, a historical survey has been made, followed by the report of problems to the society formed by the needs of the car, discussed in several environmental issues, such as jamming, noise and air pollution. This is followed by the discussion of potential solutions for how city planning could return to the focus of the human scale and perspective, in purpose to correspond with the issue of ways to decrease the car use in towns. In conclusion, the given solutions are discussed, where examples like shared space, investment in public transport, mobility management and the theory of the assembled city are included, with aid from literature, to finally conclude the essay with personal thoughts of how the planning of today, or the given solutions, really are the result of sustainability for city planning from a human perspective.

Convective snowbands is a weather phenomenon that is associated with heavy snowfall in a limited area. They are formed over ice-free parts of e.g. the Baltic Sea when there is a cold easterly airflow over relatively warm water. These convective snowbands can cause large amounts of snow along the Swedish east coast, often causing traffic hazards. Sometimes they can even paralyze an entire community.  In this study, convective snowbands that have formed over the Baltic Sea during the period 1980-2009 are examined, in order to find out how often they occur, what place they are most common and in what month they usually appear.

Syftet med denna studie var att undersöka vilka effekter luftföroreringar har på lavar och grönalger som växer på lindar, genom att jämföra lavfloran i urban miljö och i landsbygdsmiljö. Mer specifikt var syftet att utreda hur avstånd till närmaste väg, trafikintensitet och trädets exponerade respektive icke-exponerade sida gentemot en väg påverkar lavfloran i urban miljö. 18 utvalda lavarter samt grönalger eftersöktes på 86 lindar i urban miljö och 37 i landsbygdsmiljö inom Norrköpings kommun. Resultaten visade att artantalet, samt förekomsten och täckningsgraden för flertalet lavar var större i landsbygdsmiljö jämfört med urban miljö. Kortare avstånd till närmaste väg och hög trafikintensitet hade negativ effekt på flertalet lavar.

This master thesis concerns the occupational safetyenvironment at Outokompu Stainless, Avesta Work.The study is of a sociotechnical approach wherehumans are involved and interconnected in the samesystem with technology and organisation. In order toreach the corporation?s goal of zero accidents with losttime injury, the work of improving and maintainoccupational safety and health has to regard behaviourand cultural aspects. The aim of this study is todescribe the safety culture at a specific production unitand research what work which has to be done in orderto change and improve the safety culture at AvestaWork.There are several opportunities for improvementpointed out in this paper and here are some mainresults presented. First and foremost, the concern ofsafety among blue-collar is often secondary due toproduction.

When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique among care workers. Objectives: The aim of the study was to identify any advantages or disadvantages with MA?s lift, regarding shear and compression forces in the L5/S1 disc.

Background: The increasing number of actors on the market has led to a more intense competition among superstores. With this, marketing has gotten an even more essential meaning. The marketing activities superstores perform are adapted to the context in which the store is located. Purpose: The purpose of this thesis is to, from different theoretical dimensions, compare superstores? application of marketing strategies in Tokyo with the marketing strategies used by superstores in Stockholm.

Risk management has become a key ingredient for businesses all over the world. High Reliability Organizations (HRO) has distinguished themselves as experts in this area. By continuously focusing on improving their ability to manage risks they?ve been able to successfully avoid catastrophes in environments where normal accidents can be expected due to complexity and risk factors.The aim of the thesis is to improve the risk management at Apotekens Service by applying theories from HRO and safety culture. In July 2009, following the re-regulation of the Swedish pharmacy market, Apotekens Service AB was appointed national pharmacy infrastructure supplier for the Swedish health care system.

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.
