Omkonstruktion av slädsystem

Examensarbetet som beskrivs i denna rapport är ett avslutande moment för en magisterexameni Teknisk Produkt- och Produktionsframtagning på Högskolan i Halmstad.Nilsson Special Vehicles i Laholm gav i uppdrag att förbättra slädsystemet i derasbegravningsbil baserad på Mercedes E-klass. Nuvarande system är föråldrat och harendast genomgått små förändringar sedan det utvecklades. Materialet, som är olikastålprodukter, gör att vikten är hög. Utformningen av systemet är från början utformat förett annat chassi än Mercedes vilket gör att det passar dåligt i denna bilmodell. Det ärframförallt lasthöjden som påverkas negativt.

Skattning av fordonsmassa med driftstatistik

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Solenergi i Norrra Djurgårdsstaden

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Politikerns (o)etiska beslut -en fallstudie av Olof Johanssons avgång som miljöminister

Central in this paper is Olof Johansson, Swedish minister for the environment, there the focus lye on his resignation from this duty which occurred in 1994. This essay is a case study there I?m trying to identify which ethical reasons which lye behind his resignation. The relationship between politics and ethics is an interesting aspect to investigate and my ambition with this paper is to analyze that relationship in this specific case.The analysis has its focus built on the occurrence of role conflicts and the making of ethical decisions. Aspects like personal ethics versus organisational ethics, objective responsibility versus subjective responsibility etc.

Absolut avkastning på den nordiska hedgefondmarknaden : - En realitet eller önsketänkande?

Hedge funds? importance within the financial system has during the most recent years increased dramatically. These special funds are unique instruments that differ from traditional mutual funds in a variety of ways, however especially in how they expect returns. Due to the fact that hedge funds are able to hold short positions they possess the possibility to become market neutral investment vehicles.Because of this possibility to sustain positions neutral to market fluctuations, the concept of absolute returns became a unique selling point for hedge fund managers and promises of stable returns unchallenged by market conditions was assured. This research paper aims to examine the theory of absolute returns in hedge funds by examining hedge funds from the Nordic region during the last years of economic turmoil that has occurred by  analyzing the results from their strategies, partially by quantitative measurements as well as qualitative.  The results show that none of hedge fund strategies managed to deliver absolute returns over the chosen period..

Hur påverkas vård- och terapihundar av sitt arbete och hur uppfattar föraren hundens känslor?

Today's research on animal assisted interventions (AAI) has focused on the positive effects on humans. Dogs used for AAI are an expanding market, but the research on this area hasn't followed the increasing use. The few studies on dogs in this field mostly observed their cortisol-levels and are very ambiguous. I have observed the behaviour of dogs working with AAI compared to when they are off-duty to see how they are affected by their work. Their handlers where also told to make an assessment of the dog's emotions during the session.

Bränsleceller som applikation i bilar : Enstudie av Fuel Cell Electric Vehicles och deras potential för framtida kommersialisering

Användningen av personbilar har ökat stadigt i Sverige och världen i stort de senasteåren, vilket lett till ökade utsläpp av koldioxid. Samtidigt har oljepriset nåttrekordnivåer, och många menar att utvinningen av olja redan har nått sin topp. EU hardessutom satt som mål att medeltemperaturen på jorden inte får stiga med mer än maxtvå grader Celsius, och att till år 2050 reducera koldioxidutsläppen med 80 %. Detta ärenbart möjligt om nya, gröna drivmedel och drivlinor fortsätter utvecklas ochframförallt kommersialiseras. Användningen av förnyelsebara energikällor har ökatkraftigt, vilket skapat förutsättningar för bilar drivna av el.

Den nöjda och osynliga bibliotekarien : Myt och verklighet - Vad är trivsel för bibliotekarier?

The aim of this thesis is to explore the job satisfaction of librarians and try to nuance stereotypes, which the public has and which still exist in massmedia concerning librarians and their work. The study is qualitative and based mainly on semistructured interviews with ten libraries born between 1937s and 1973s of which eight are women and two men. Furthermore, I have divided them into two groups according to age in order to see if there are differencies between the older and the younger concerning job satisfaction. In addition, I have used participant observation to some extent. My assumption is that job satisfaction is effected both by individual factors and environmental factors at work.

Tv-spel i skolans värdegrundsarbete: en intersektionell
analys av interaktiva medier

Den här studien undersöker didaktiska potentialer med att använda tv-spel i gymnasieskolans litteraturundervisning gällande värdegrundsarbete. I den första delen av arbetet presenteras tidigare forskning kring spel som forskningsområde och den relativa bristen av sådan forskning. Vidare presenteras begreppet intersektionalitet som analysmetod samt det svår- och mångtolkade begreppet värdegrunden ur läroplanen som i ett eget avsnitt diskuteras ur ett moralfilosofiskt perspektiv. I arbetets andra del tillämpar vi den intersektionella analysmetoden på tre olika spel: Dragon Age Origins, Rule of Rose och Call of Duty: Modern Warfare 2. Resultaten är senare diskuterade i arbetets sista och avslutande del.

Framtidens elbilar utmanar nutidens elnät : Påverkan av ett ökat antal elbilar på ett halländskt elnät

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

Säkrare sjöfart? : - en processanalys av föreskrifter omläkarundersökning för sjöfolk.

Arbetsuppgifterna på ett fartyg kan innefatta hård fysisk påfrestning samt arbete i mörker, påhög höjd och i slutna utrymmen vilket betyder att sjöfolk måste vara lämpliga för tjänstgöringen.De nationella reglerna för medicinsk lämplighet för sjöfolk skiljer sig trots att deninternationella standarden är densamma för alla. Syftet med denna rapport är att åskådliggöraskillnaderna mellan regelverken om läkarintyg för sjöfolk i de skandinaviska länderna ochundersöka historien bakom de svenska föreskrifterna.Vår slutsats är att det skulle gagna Sverige att återinföra Sjömansläkare, som troligtvis är merkompetenta än en icke specialiserad läkare vad gäller tjänstbarhetsbedömning för sjömän.Systemet med sjömansläkare är fortfarande i bruk och fungerar väl i både Danmark ochNorge.Slutligen sammanfattas rapporten av författarnas egna reflektioner kring ämnet i relation tillresultatet. Förslag till vidare forskning återfinns i slutet..

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues

Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

Mörkerkörning: Realtidssimulering och visualisering av fordonsbelysning för mörkerkörning i körsimulator

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.

Rättsenlighet och ansvarstagande i de ensamkommande flyktingbarnens asylprocess

Earlier this year the Swedish migration board gave a part of their responsibility for the separated children to those municipalities that have signed an agreement with them, so that the children can get the best handling of their matters and also to lift the heavy pressure of the Swedish migration board. Our aim in this paper is to see how this division is made and which areas of responsibility they have. We want to see how this process is being handled in relation to these children?s rights, the Convention on the Rights of the Child and the Swedish law. To get the best information possible we used a qualitative method.

Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
