Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

Traditionella flygbolags åtgärder efter lågprisflygets inträde på marknaden : En fallstudie av SAS & Finnair

The de-regulation of commercial air traffic in the early 1990?s lead to that many new airline companies entered the market. Many of these new actors were low budget airlines which meant that the traditional airlines met a new type of competition. This situation contributed to the fact that ticket prices dropped in many countries. It has become more and more common that the traveller prefers to fly with low budget airlines rather than with the traditional airlines.

Hur effektiv och säker är fingolimod vid behandling av multipel skleros jämfört med natalizumab?

Multipel skleros (MS) är en kronisk immunologisk sjukdom som slår på centrala nervsystemet (CNS) och kan leda till minskad neurologisk funktion. I Sverige finns 17 500 personer som fått en MS-diagnos. Den vanligaste åldern för insjuknande är 20-40 år och sjukdomen är dubbelt så vanlig bland kvinnor som bland män. Om patienterna inte får behandling finns risk för kraftiga funktionsnedsättningar. Syftet med detta arbete var att undersöka effekten och säkerheten med det perorala läkemedlet fingolimod jämfört med intravenös behandling med natalizumab vid MS.

Purpose: The study's purpose is to study the relationship between ownership concentration and liquidity, and whether other factors might explain differences in liquidity. Method: The study is conducted with a quantitative method and it?s based on data collected from 2006-2011 for companies listed on Nasdaq OMX.

Hur effektiv och säker är rekombinant och renad plasma faktor VIII-behandling för hemofili A patienter?

Haemophilia is an inherited disease which causes increased bleeding due to defect clotting factors VIII and/or IX. There are two forms of haemophilia, A and B, which both are X-linked and due to mutations of the genes of factor VIII and factor IX respectively. This study focuses on Haemophilia A and thereby factor VIII.The drugs that are available on the Swedish market today for patients with haemophilia A include Factor VIII(FVIII), which has been purified from human plasma and recombinant factor VIII(rFVIII). The main goal of this study is to gain a better understanding of the effects of treatment of haemophilia A with either purified plasma factor VIII or recombinant factor VIII on reducing or preventing bleeding and on side effects.  The study was designed as a literature review and searches were carried out in PubMed at the Linnaeus University library.  The criteria for selection of articles were: patients with haemophilia, treatment with plasma derived and/or recombinant factor VIII as well as clinical studies.

Anonymous ansikten : En undersökningar av några svenska dagstidningars konstruktioner av hackernätverket Anonymous

This study examines how a couple of Swedish daily newspapers construct the hacker network Anonymous, with an aim to discuss its possible effects. The question was: In which ways is the network Anonymous constructed in a few Swedish newspapers?                      26 articles from four chosen newspaper were analysed, but because of many similarities in content, only 10 were chosen for deep analysis. With Fairclough's model of critical discourse analysis as chosen method, constructions varying from the images of heroes to villains were found as a result. The most common construction was that of Anonymous as a threat, which was most often exaggerated compared to what actions were actually described in the texts.

 Solenergi En del i ett långsiktigt, hållbart byggande

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Cykelgarage : en litteraturstudie om cykelgarage och dess samhällsnytta

När samhället tvingas att anpassa sig efter klimatförändringar och sinande oljeresurser uppkommer nya problem att handskas med för stadsplanerare. Cykelgarage, som är ett relativt nytt fenomen i Sverige, kan skapa bättre förutsättningar och erbjuda service för cyklister som parkerar vid stationer och resecentrum. De kan bidra till att få fler att cykla och att åka kollektivtrafik. I en framtid som ställer högre krav på en hållbar infrastruktur behöver vi satsa mer på kollektivtrafik och cyklism. Vi pratar om förtätning av våra städer och ser den positiva verkan det ger men det ställer samtidigt högre krav på stadsplaneringen.

FASTIGHETSPAKETERING : Alltid ett godkänt förfarande?

Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.

Nutrient effects on microorganism communities in nutrient poor soils

Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest. The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.

Bullertunneln : En utredning kring en ny bullerlösning vid trafikleder

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.
