Ny metod fo?r ma?tning av va?gkvalitet : En statistisk studie o?ver samband mellan va?gkvalitet och socioekonomisk utveckling

New method for measuring road quality- A statisticalstudy of the relationship between road quality andsocioeconomic development A new tool with implications for road maintenance has the potential to yield statistical data for road quality in a large number of regions. This thesis investigates the possibility to develop a method, from this data, for evaluating the effects of road quality on socioeconomic development.The thesis is essentially divided into two parts. Part one looks to qualitatively establish the link between socioeconomic development and road quality and the second part focuses on how to develop a method for evaluating the effects of road quality on socioeconomic development. A method was devised using categorical data and a multinomial regression model. This method provides a comprehensive overview of the complex relationship between a variety of different variables.

Bränsleövergångar : Miljölagstiftningarnas inverkan på fartygsdriften

Under vårt sista år var vi intresserade av att ta reda på de problem som vi kan stöta på i våra yrkesroller som fartygsingenjörer. Arbetet tar upp de tekniska problem som uppstår p.g.a. de allt strängare kraven på minskade svavelutsläpp från fartyg. De tekniska problemen härstammar från de olika bränslekvaliteternas vitt skilda egenskaper. Som svar på dessa problem har det utvecklats tekniska lösningar varav två stycken har tagits upp i detta arbete.För att ta reda på vilka tekniska problem som kan uppstå tog vi del av den berörda utrustningens tillverkares erfarenheter enligt empirisk modell.

En fallstudie över miljömålsarbetet på fyra länsstyrelser : Beskrivning och analys av det regionala miljömålsarbetet i Mellansverige.

The Swedish system of environmental quality objectives is a so-called MBO, Management By Objective and has the purpose to guide the Swedish society towards sustainable ecological development. The system involves the whole society from the parliament and the government down to individual citizens. At the regional level, it is the county administrative boards that are responsible for the work with the system of environmental objectives. At the County Administrative Board of Västmanland County, it is the environmental unit who is in charge of work with the environmental objectives and they want input for how to improve their work with the environmental objectives, both internally at the Administrative Board and externally with external parties.The main purpose and goal of the study is to present the work of four other county administrative boards regarding their work with the environmental quality objectives and to identify external parties? opinions of how they want the County Board of Västmanland county to work with them in this matter.The work is designed as a case study of four county councils, where the environmental objectives coordinators at the four county administrative boards were interviewed about their work with environmental quality objectives.

GROT-transport från norra till södra Sverige

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

Meningen med livet : hur 15-åringar i en stor och en liten stad i Sverige ser på livskvalitet

There are many good reasons to ponder about what it is that makes life worth living. To observe and reflect on what it is that gives a person a good quality of life is arguably the essential core of social-work. The aim of this research was to investigate how 15-year old youths interpret quality of life. The key areas that we explored in order to meet the research aims were: what did the youths interpret as a good quality of life for a 15-year old and for an adult, how did they view their own quality of life, and did they think that the regional context (i.e. if one lives in a big city or in a small town) affects how one interpret quality of life.The studywas based on interviews with four boys and four girls.

Kvantifiering av osäkerheter i lyftkraftsmodellen

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

Vad är kvalitet i ledarskap? : Teorier, modeller och verkligheten

In this qualitative study the authors explores, by studying several quality-development models what quality in leadership is. The models are: Total Quality Management; SIQ?s model for customer-oriented organizational development; the EFQM excellence model; the ISO 9000:2000 standard; and Six Sigma. These models will be compared from Deming?s list for upper management; the Situational Leadership Theory; and the Contingency Theory.

Därom tvista de lärde : en analys av kvalitetsbegreppet och dess betydelse fö utformandet av bibliotekets inköpspolicy

In public libraries there seems to be an unspoken consensus on what literary quality is. At the same time librarians are always eager to express the opinion that quality lies in the eye of the beholder. Quality is, it is said, something that you don t have to define. But at the same time it s up to everyone to decide what quality means to them. What I have been missing from the discussion in libraries about literary quality is a theoretical awareness about what it means to divide literature into higher and lower spheres.

Utveckling av en ljudsimulator med anva?ndarcentrerad design : Tilla?mpad matematik fo?r ba?ttre konsertupplevelse

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Portal till det förflutna : en arkeologisk kvalitetskontrollerad ämnesportal som resurs för universitetsutbildning i Lund.

The purpose of this essay ("Gateway to the Past. An archaeological quality controlled subject gateway as a resource for higher education in Lund") is to examine how a quality controlled subject gateway could increase the quality of the information supply for the Department of Archaeology and Ancient History at Lund University. The essay gives a brief background to subject gateways and also describes the Department and its subjects (prehistoric archaeology, medieval archaeology, osteology and classical studies) . The essay consists of a questionnaire distributed to parts of the target group as well as an investigation of three particular subject gateways: NordArk, ARGE and The Labyrinth. The essay also contains an exposition of how archaeologists seek information, of the structure of the archaeological subjects and of classification systems for quality controlled subject gateways.

Etanolmarknaden i Brasilien : etanol som fordonsbränsle

According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for producing ethanol and is the leading producer and exporter of fuel ethanol. My purpose with this paper is to investigate why Brazil decided to develop ethanol production on a large-scale operation and to find out today?s situation. Focus will mainly be on ethanol production with sugarcane as a feedstock.

Rektors systematiska kvalitetsarbete ur ett helhetsperspektiv

A systematic quality work is essential for anyone working in preschool, school,kindergarten and adult education to give children and students an equal education.Skollagen (2010:800) indicates that quality work should be focused on the nationalgoals of education. According to Skolverkets allmänna råd med kommentarer omsystematiskt kvalitetsarbete - för skolväsendet (2012) is the work to develop quality acontinuous process. Everyone's involvement and participation is therefore essential.Systematic quality work means to systematically and continuously monitor theactivities, analyze performance against national targets and based on that plan anddevelop. Although the work has been driven outside governmental policy documentssince 1997 shows, among others, Skolinspektionens audits of municipalities andschools that there is major deficiencies in the obligation to conduct a systematicquality work. It appears that more than half of the surveyed schools had deficienciesin its system quality work.This is the starting position this study takes on to and through literature review,document studies and interviews of principals is the subject problematized.

En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Nobel och August på biblioteket ? Bibliotekariers attityder och förhållningssätt gentemot litterära priser

The aim of this Master?s thesis is to examine attitudes and standpoints amongst librarians at the Swedish public library towards literary awards and awarded literature. The questions posed in the study are: What attitudes are expressed amongst these librarians towards the Nobel Prize in literature, the August Prize and literary awards and awarded literature in general? What significance do the Nobel Prize in literature, the August Prize and other literary awards have concerning purchase and display at these public libraries? How is awarded literature perceived and how do they talk about it concerning quality and are questions of quality significant? Qualitative interviews with seven librarians at four different public libraries have been done. Theories regarding J?rgen Habermas the bourgeois public sphere and Pierre Bourdieu?s terms habitus, field and capital have been used as to explain the library as a public sphere.
