The aim of the Master?s Thesis work is to study and develop algorithms for autonomous Travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

This report discusses the development of an autonomous system that can Travel a distance of atleast 30 meters on two wheels. The system, the robot, detects black lines and stops if one isdetected. A remote control can be used to start and stop the robot. The robot is constructed ofmainly steel with smaller, more detailed, parts in plastic. A significant amout of time has beenused to enable the robot to balance on its own.

The project involves implementing a finished dispersion model into ArcGIS. The goal of the tool is to show how dangerous and toxic substances will Travel in the ground after long periods. The goal of the project is to understand GIS in general, what it is used for and gain an insight into how developing tools for ArcGIS is, what challenges might exists. Understanding the type of data that can be stored and accessed in ArcGIS a long with the tools and functionality offered by the system when using Python as the main language for development. A prototype of the tool is created..

VARN A network multiplayer 2D action game written in Java. All games that support any form of play across networks is in one way or another affected by the delay, or "ping", that occurs from the time it takes for information to Travel over the wires. Not only does it take time, it varies depending on how far away the connected partner is and the current status of the network you are on. Through the years a lot of different methods have been developed to combat these delays. I have reviewed some of these methods and implemented a synchronization system in Java meant to be used in online action multiplayer games..

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.

This bachelor thesis in tourism studies focuses on people's use of social media related to Travel. The paper aims to provide a wider knowledge of tourist?s propensity to display destinations through social media and how they perceive others that display Travelling. This is put in relation to the term of social status in order to find out if there is a possible link. The intention was to provide an insight into the phenomenon to contribute new awareness that destinations can exploit in their marketing.

Abstract The purpose of this work is to investigate children?s perception of Swedish birds. Through qualitative questions there were twelve children interviewed. I showed the pictures for the children of different animals that we discussed but with focus on birds. The children could partly distinguish which of the pictures that represented birds and who did not.

This paper examines pupils? conception of the Swedish schools constitutive values expressed in the Swedish curriculum. The main question was, at to what extent the schools constitutive values have influenced the pupils conception of their own values. That question problematizes the relation between values, constructed and carried by central administration, and their interpretation at local level by pupils. The study was conducted with qualitative analysis which included qualitative interviews with seven pupils in the last year of the Swedish school system.

Vårt arbete började när fick i uppdrag av resebyrån Prima Travel att finna möjligheter för dem att effektivisera dess organisation i takt med att dess omsättning ökade vilket satte högre krav på verksamheten. Förutsättning var att effektivisera organisationen men fortfarande hålla den lika smal som i nuläget. Företaget hade under en tid upplevt en allt större efterfrågan på deras produkter samt en ökande omsättning. För att finna lösningar på uppdraget utfördes en processkartläggning för att förstå hur organisationen fungerade i nuläget. Detta gav en god förståelse för företaget och dess aktiviteter.

Denna uppsats behandlar den svenska resemarknaden och om olika reseföretags tillämpning av konkurrensstrategier kan skapa framgång och hjälpa dem att överleva på en mogen resemarknad. Arbetet bygger på en jämförelse mellan tre reseföretag som distribuerar resor, för att undersöka och analysera olika konkurrensstrategiers verkan på den svenska resemarknaden.Tre reseföretag med olika inriktningar på marknaden jämförs i uppsatsen, KILROY Travels Sweden AB, Ticket Travel Group AB och MyTravel Sweden. Undersökningen bygger på en kvalitativ metod genom personliga intervjuer med respektive företag.I analysen görs en jämförelse av reseföretagen som konkurrenter till varandra. Det som har framkommit i intervjuerna jämförs med utvalda teorier i analysen. En kombination av konkurrensstrategier används för att utreda vilka köpare och leverantörer som finns och om det finns hot från potentiella etablerare och substitut.

Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.

The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective Travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..
