The interaction between the driver, the car and the road is essential for the road safety. This case study focuses on the road condition and its effect regarding road safety issues. By studying and isolating the road condition aspect and its contributing role to the accident occurrence, the aim is to explore their relationship, as well as highlight the road parameters that are commonly associated with accident occurrence. This result will be used to develop and increase awareness of the impact of poor road alignment and poor road surface conditions on traffic safety, in order to prevent these accidents from occurring. The road parameters chosen for this study include side friction, cross slope and rut bottom cross slope, road texture, curvature, drainage gradient and rutting.The case study was limited to lv 360 in Va?sterbotten, where all accidents with an unclear cause of the accident were studied, between 2003 and 2012 were carefully studied and assessed based on the condition of the road at the time of the accident.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

 This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy Vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.

Obemannade system blir allt vanligare både på den militära och kommersiella marknaden. Unmanned Aerial Vehicle, i vardagsspråk benämnt som drönare, är ett flygplan som ombord saknar en mänsklig pilot. Då utbudet och efterfrågan av obemannade farkoster ökar måste tillverkarna lägga mer fokus på att kunna erbjuda hela system, vilket innebär att vid försäljning kan ett komplett system för obemannade farkoster erbjudas. Därför är behovet av tillbehör och kringutrustning idag lika viktigt som det obemannade flygplanet.Unmanned Systems Group grundades 2012 med verksamhet i både Schweiz och Sverige. Företaget förser den globala marknaden med innovativa produkter och tekniska lösningar inom området för Remotely Piloted Aircraft Systems.

Stockholm Gas AB säljer i huvudsak två olika produkter. Den ena är stadsgas och den andra är fordonsgas. Båda produkterna skall på sikt i huvudsak ha biogas som råvara. I dagsläget är det dock så att stadsgasen till största delen består av naturgas blandad med luft.Stockholm Gas AB har genomgått stora förändringar och står inför nya. År 2011 togs ett stort steg i Stockholm Gas klimat- och miljöriktiga utveckling.

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

This master's thesis sets out to explore information literacy in a contextualized learning environment with emphasis on students at a vocationally oriented program in the Swedish upper secondary school. The concept of information literacy is widely discussed and furthermore a common subject for research within the field of Library and Information Science. Information literacy can be described as a set of skills or a range of attributes defining an information literate person. The skills and/or attributes facilitating the development of critical thinking and problem-solving skills are often linked to knowledge about computers and libraries.Another view on the concept of information literacy has been developed by the Australian researcher Annemaree Lloyd. She stresses the importance of social and physical information sources and that these also should be included in the development of information literacy.

VSEM project and the need for a more efficient way of handling requirements andinformation are highly apparent.The overall objective of this thesis is divided into two parts:1. To identify criteria/factors leading to a successful introduction of an informationmanagement system.2. To develop an implementation process for a requirement management system ?the first step towards a PLM system in EE development at VCC.This will be done through interviews with employees, a literature review and an analysisof studies of three earlier projects within VCC.The conclusion of this study shows the great need for change in work methods fordesigners handling information and requirements. An implementation process has beenidentified with guidelines on how to handle different phases of the process.

Syfte ? Studiens syfte är att öka kunskapen om hur fordonstillverkares affärsmodeller påverkas vid förändring av statliga regelverk genom att studera ett framtida införande av HCT i Sverige. HCT, High Capacity Transports, är ett samlingsnamn för lastbilar som är tyngre och/eller längre än vad gällande lagstiftning tillåter. Regelförändringen övervägs för att sänka kostnader och miljöpåverkan. Metod ? Arbetet har genomförts i form av en case-studie.

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Atopic dermatitis (AD) is a complex, often lifelong allergic disease affecting around 10 % of both dogs and humans. The hallmark symptom is severe pruritus, causing a lowered quality of life. Mast cells (MCs) are known to play an important part of the immunopathogenesis, promoting a faulty T helper cell type 2 (Th-2) response which follows by a production of specific immunoglobulin E (IgE) antibodies towards environmental allergens (Ag). To further investigate the role of MCs and its mediators in the progression of AD, a low-calcemic vitamin D3 analog (MC903) was used to induce AD-like symptoms locally on the ears of two different knock-out (KO) mouse strains. The first strain was Wsh-/- mice deficient in MCs.

Automated Guided Vehicles, AGV:er, används i huvudsak som monteringsplattform inom tung fordonsindustri. En AGV kan användas vid montering av motorer, växellådor och chas-sin. AGV:n transporterar produkten genom en slinga i fabriken, där produkten monteras. Idag säljs AGV:n med ett löfte om femfaldig säkerhet mot brott för alla de ingående komponenter-na. AGV:n är konstruerad för att bära upp en last på maximalt 1800 kg, med säkerhetsfaktorn inkluderad.

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor Vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.
