Informationskompetens i praktiken -en fallstudie av informationskompetens och lärande hos en grupp fordonselever

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.

Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock

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.

The role of mast cells and mast cell mediators in the development of atopic dermatitis in a mouse model

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.

Hållfasthetsanalys av infästningmellan AGV och motor : med hänsyn till femfaldig säkerhet mot brott

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.

Snabbt, säkert eller skönt? : Cyklisters preferenser i trafiken

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.

Re-design av BEV-heater

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.

MiFID och dess inverkan på den europeiska aktiemarknaden : ? En studie av hur fragmenterad handel påverkar marknadsövervakning och distribuering av handelsinformation

I november 2007 införde politikerna i Bryssel ett direktiv med avsikt att öppna upp för konkurrens och öka transparensen på Europas aktiemarknader. Börsmonopolet bröts upp och aktiemarknaden fragmenterades, det blev då möjligt att handla aktier på andra marknadsplatser än enbart på primärmarknaden.Syftet med uppsatsen är att undersöka hur den fragmenterade handeln påverkar marknadsövervakningen och informationsflöden mellan marknadsplatserna. Är marknadsplatsernas informationssamarbete tillräckligt bra för att skapa en säker och effektiv marknad? Har riskerna för marknadsmissbruk ökat och hur väl står direktivet rustat mot insynspersonshandel? För att få en inblick i ämnet gjordes en litteraturstudie i MiFID och dess påverkan på marknaden. Rapporter, artiklar, lagtexter och direktivets artiklar ligger som grund för utformandet av den empiriska undersökningen som bestod av intervjuer med personer som är väl insatta i ämnet och en enkätundersökning till olika marknadsplatser som handlar med svensknoterade aktier.Resultatet av den empiriska undersökningen visar att det finns stora problem med marknadsövervakningen och informationsflöden på den europeiska aktiemarknaden.

Kartläggning och analys av livslängdsstyrande faktorer för dragbrotschverktyg

Detta examensarbete utfördes vid Uppsala universitet i samarbete med Scania CV AB. Scania Commercial Vehicle Aktiebolag, Scania CV AB, är en tillverkare av tunga lastbilar, bussar samt industri- och marinmotorer. På Scania transmission i Södertälje finns ett av företagets största och dyraste verktyg. I dragbrotschningsprocesser används dragbrotschverktyg som per styck kostar allt från 50 000kr och upp till strax över 1 miljon kronor beroende på storlek och utformning.Uppdragets syfte är att kartlägga faktorer som styr ett dragbrotschverktygs livslängd och undersöka alternativ som bidrar till att sänka dragbrotschningsprocessens kostnad per producerad artikel. Mål är att göra en beskrivning av nuvarande system och processer samt kartlägga vilka faktorer som styr dragbrotschverktygens livslängd.

Ruttdetektering av tågtrafik

This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.
