Denna uppsats är en del av trafiksäkerhetsprojektet FICA (Factors Influencing the Causation of Accidents and Incidents), vars målsättning är att genom en förståelse för förarbeteende kunna utveckla aktiv säkerhetsteknologi för fordon. Inom detta projekt kommer en metod för olycksanalys, DREAM (Driving Reliability and Error Analysis Method), att användas. Den här uppsatsen handlar om att utvärdera och utveckla denna analysmetod. Arbetet med metoden har främst gällt användbarhetsaspekter av DREAM. Även olika kvalitetsaspekter som till exempel replikerbarhet, har undersökts.

Studiens syfte är att studera de bakomliggande sociala faktorerna som kan bidra till utvecklingen av datorspelsberoende. Studien genomfördes kvalitativt genom att intervjua fem personer som själva ansett sig vara datorspelsberoende. Tidigare forskning som berört detta ämne har handlat om hur användare påverkas av spelet, och inte vad som lett fram tillatt det intensiva spelandet påbörjades. Som teoretisk utgångspunkt för studien valdes den utvecklingsekologiska modellen som användes för att studera individen utifrån ett mikro-,meso-, exo-, makroperspektiv. Våra data visar resultat främst på en mikronivå där vi fann att en problematik på denna nivå fanns genomgående för samtliga informanter.

Executive summaryOn todays fashion market, no product will become successful without branding. The competition in the growing fashion market is tuff, which makes it hard to reach the target costumers. Competition makes it difficult to reach out with a message and it is crucial to differentiate the company in the consumer market.Differentiation of the brand requires knowledge of competitors who are on the market. Understanding competitors, as well as the customer, is the basis for a well functioning communication. Different markets have different conditions and today's global market is complex.

This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..

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.

Denna rapport beskriver framtagande av ett koncept för ett geografiskt informationssystem som är anpassat för att köra på moderna mobila enheter ute i fält. Detta sätter krav på systemet vad gäller beräkningskraft, lagringsutrymme samt möjligheten att klara av intermittent datakommunikation. För att ta fram systemet utfördes först en förstudie med databaser och sökmotorer användes för att hitta relevant information och relevanta artiklar som kunde hjälpa till vid framtagningen av systemet. Denna fakta tillsammans med utförda tester och ?trial-and-error?-programmering ledde i slutändan till ett koncept som klarade av de krav som ställdes på systemet.

AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.

This is an essay concerning the differences between boys? and girls? way of learning and how this difference influences the teaching in the technology subject. The method is divided in two. The first part is based on a survey over literature about teaching girls and boys in the technology subject. The second part is based on interviews with three male teachers in the same subject.

Actor-observer bias är tendensen där människan som aktörer tillskriver sitt beteende till yttre omständigheter medan observatörer tenderar till att tillskriva aktörens beteende till personliga faktorer. Syftet med denna studie var att få en klarare bild av hur människor i sin roll som aktör eller observatör attribuerar ett riskabelt bilkörningsbeteende. Deltagarna bestod av 101 svenska studenter från en högskola i Mellansverige varav 77 stycken var kvinnor och 24 stycken var män. Deltagarna fick svara på en enkät angående actor-observer bias och riskfullt bilkörningsbeteende. Resultaten visade att andras beteende förklaras mer av personliga egenskaper än då personen själv kör riskfullt medan yttre omständigheter inte gav skillnad för vare sig andra eller en själv.

Skiascopy, also called retinoscopy, is a method for determining the refractive power of the eye. There are only a few, old studies made on equine refraction. The aim of this study was to investigate the refractive power in a population of Swedish horses. The study consists of a review of relevant studies done on animals and an experimental part where the refractive power of 93 horses of different age, breed and usage was examined. A pilot study of 12 horses was performed regarding the importance of cycloplegia when doing skiascopy on horses. The results of the pilot study show no significant difference in the skiascopy results between the group before and after cycloplegia were induced. Consequently, there is no need of inducing cycloplegia before doing skiascopy in adult horses. The study shows that horses usually were emmetropic (normally sighted) with minor deviations toward myopia or hyperopia.

Börsnoterade bolag i spelbranschen med pokerklienter har det senaste året haft kraftigt stigande aktiekurser. Vår uppsats ämnar undersöka om dessa företag är övervärderade på grund av det stora ökade intresset för poker. Vi har genomfört analyser med hjälp av target price och multipelvärdering. Vi har förklarat hur regressioner på dessa bolagen ser ut samt koncentrerat oss ytterligare på vad som driver Unibets aktiekurs. Det resultat vi har kommit fram till är att branschen i sin helhet inte är övervärderad utan snarare korrekt prissatt, med reservation för eventuell undervärdering.

BARA BOSTÄDERPlacerat mellan Bollmora flerbostadshus och den gamla landsvägen breder Tyresö gymnasium ut sig. Vår ingång blir att riva skolan, materialet ?kremeras? till tegelkross och sprids i en röd löparbana längs den befintliga landsvägen, att tillåtas glömma för att senare minnas. Gymnasiet förstås som en del av det befintliga landskapet, det ändrar bara form och byter plats.Vad händer när man släcker ett lager i AutoCad?Det närvarar i sin frånvaro.

2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.

In the spring of 2009 Silva Sweden AB was contacted for a collaboration within the scope of a MasterThesis project.

The objective of this Master Thesis has therefore been todevelop and design a multi training device that records the user?s physical performance during severalactivities. The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.

The discovery and excavation of Long Barrows has been one of the major developments in the understanding of the Early Neolithic in Southern Scandinavia during the last decade. The Long Barrows are one of the oldest monumental burial forms that we see in northern Europe in the neolithic. They are also the first example of a common idea that is connected to a monumental burial form amongst the people. In this essay I attempt to show that there actually are quite a large number of Long Barrows in Scandinavia that show similarities with Long Barrows in well-known areas such as Kujavia (Poland) and Pommerania (Germany/Poland), in both architecture and location in the landscape. I also scrutinise some theories regarding this phenomenon and discuss, and i some cases, criticise them.
