Application of Design for Safer Urban Roads and Junctions: Selected Countermeasures
Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Föräldraroll - ett framtidsyrke? : en empirisk studie om hur sex föräldrar ser på föräldrarollen i ljuset av utbildningsidealet
Over the past decade there has been considerable debate in the media concerning the necessity of educating parents in how to be better parents, and strengthening their parental role. This question has also been debated at a national level, resulting in the state commissioning a number of official investigations into the problems that parental education could resolve. A growing body of scientific studies have shown that parental-educational programmes play a strong role in preventing behavioural problems amongst children and teenagers. Many Councils in Sweden already offer these parental courses to their citizens, but discussions are ongoing as to whether these courses should be obligatory for all parents before or near to the moment that they begin to have children. This conclusion has been supported by the official investigations commissioned to look into this issue.
En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller
This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.
Lärdom och fostran : En vägledning till skolarkiven på landsarkivet i Uppsala
The Regional State Archive in Uppsala [Landsarkivet i Uppsala] has several archives left from various types of educational institutions in the counties of Dalarna, Södermanland, Uppsala, Västmanland and Örebro. This archiv-al guide reveals the main content of some of the school archives. It goes through the archives of the elementary school, state secondary grammar schools and private secondary grammar schools. A few special schools for the blind and the deaf children are included. The essay also brings up records from community homes and reformato-ries for children and young adults who experienced certain difficulties and therefore could not adjust to the ordi-nary educational system.
Estimering av kreditbetyg - Syntetisk rating med Ordered Probit Model
Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.
På gröna stigar : En vandring i det ekokritiska landskapet
In this essay I have described ecocriticism as a theory with several different subfields that are inspired by a cross-disciplinary approach, such as green culture studies, ecofeminism, and postcolonial ecocriticism. After a short summary of the background of ecocritical studies I analyze the various subfields, take a closer look at their contents and present various examples of ecocritical thinking. A presentation of the commonly used concepts within the discipline and some reflections on these is followed by my final discussion, where I state that even though ecocriticism is a relatively new theory and the concept doesn?t have a clear definition as yet, it is in my view a useful tool for analysis and can with time make valuable contributions to literary studies, not least by introducing a number of new perspectives..
CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet
During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.
En studie om införandet av expected loss model : - En mer tillförlitlig och relevant metod för nedskrivning av finansiella tillgångar?
Accounting has been critized for being one of the leading factors in the latest financial crisis. One of the primary problem areas was identified as delayed recogonition of losses on financial instruments. Consequently, a new impairment model is being developed and is to be namned expected loss model. The difference from the present model, incurred loss model, is that it takes losses into consideration on an much earlier level. Even though the model may be theoretically feasible, in practice it may implicate a number of issues.
Utveckling och implementering av ett audiopejlsystem baserat på tidsdifferensmätning
The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.
Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
Realistisk restidsberäkning för comodal reseplanering
With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.An investigation of the available data on maps and travel times shows where the currently used methods are lacking.
Turkiskt EU-medlemskap : En kritisk idéanalys med civilisationernas kamp som teoretiskt perspektiv
This thesis aims to study obstacles which Turkey faces regarding EU accession. The main focus will be at the historical context and background information to clarify Turkey-EU relationship and institutional aspects such as; the Copenhagen criteria will be analyzed. Interaction between identity politics and Turkeys Europeanization project will be examined by analyzing arguments regarding this issue. The historical context is important for realizing in how Turkey's negotiation process is affected and how the process is evolved. By examining this, a more transparent understanding is going to develop in the issue of why Turkey never will be able to identify itself with the EU.Analysis regarding why Turkey as a secular state develops into an increasingly Islamized state is highlighted.
