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.
Allt som är fast förflyktigas : Föreställningar om arbete och sambandet mellan arbete, tillväxt och välfärd i senmodernitetens Sverige
The focus of this thesis is the conception of work and the relation between work, economic growth and welfare in today?s Sweden in the editorial of Dagens Nyheter (DN), which is the main morning paper in Sweden.As the theoretical foundation of this thesis is social constructionism and the method being used is critical discourse analysis, the language is considered as an important source for the construction of value and meaning of work. In that context it is important to investigate how DN, by certain ways of representing reality, preserves a certain view of the human being, the society and the economy. Which ideological ideas underlie the conception of work that emerges in DN? What social consequences will these ideas have?The thesis discusses the ?truths? that the editorialists mediate concerning for example the view of the human being as guided by rational choice and the view of economic growth as the main goal for social life.One of the conclusions is that DN considers work as a means for economic growth as economic growth is regarded fundamental for the survival of the welfare state..
Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

Innovativ Pumputrustning
This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

Produktprogrammet omfattar bergborrning, bergavverkning, krossning, lastning och transportlösningar.Uppdraget handlade främst om pulvertransporten som företaget vill automatisera för att förbättra ergonomin åt operatörerna som i dagsläget drar pulvertunnan i en spårbana. Under projektets gång har författaren tagit med nya mål som anses kunna integreras med automatiseringen av pulvertransporten, vilket var att hitta lösning för att köpa in en ny burkvändare och förbättra pulverhanteringen. Utöver detta hade företaget även övriga mål som gick ut på att lösningen bör vara säker utifrån produktionssynvinkel samt att man skulle ta hänsyn till damm exponeringen.För det framtida tillståndet har det under projektets gång analyserats hur planeringen arbetar samt hur produktionen fungerar i dagsläget genom att bland annat räkna fram viktiga nyckeltal för att kunna ta fram de enklaste och mest effektiva lösningar till målen som företaget satt upp..
Socialarbetares syn på datorspelande ungdomar : En intervjustudie om socialarbetares problematisering av ett nytt fenomen
The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Automatisk tändning till modern vedpanna
If you have access to wood, a wood burning boiler is a cheap way to heat your home, but it is certainly not the most convenient option. Wood requires many operations and management, which takes time. One way to reduce this workload is to have a modern boiler with automatic ignition. Enertech/CTC has a desire to create an accessory with automatic ignition to a modern wood burning boiler. Today there is no boiler on the market that can ignite firewood automatically without the introduction of paper and sticks.
En nyanserad eller homogen judendom? : Hur fem religionsläroböcker för gymnasiet framställer judendomen
This essay aims to examine if five high school textbooks represent Judaism as homogeneous or diverse. The purpose is to see if textbooks add a diverse or homogeneous view on Judaism. The methods for this essay are a qualitative content analysis and an image analysis. The results tells us that both homogeneous and heterogeneous tendencies can be found in the textbooks to a certain extent. The homogeneous tendencies can be explained as an aftereffect of the textbooks? authors becoming limited by their schedule, amount of pages and so on.
Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö
With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.
Fel i produktionen : En studie om uppkomna fel i två anläggningsprojekt
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.

Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information
Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.
