Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

ABSTRACTDuring the last decades, environmental impacts have increased significantly, much due to the great traffic flows within cities. Therefore, to reduce these impacts and encourage a healthy way of living, it has in recent years become vital to generate safer and more sustainable and flexible modes of transportation. In order to do so, authorities and physical planners must work together to find viable solutions to incorporate in the infrastructure and offer alternative transport modes ? such as walking, cycling and public transportation. The purpose of this thesis is to examine the development of the cycling infrastructure in the city of Västerås and whether it is possible to expand bicycle commuting alongside public transportation. The thesis consequently aims to study how different physical planners within Västerås municipality work with traffic related questions.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

Vårt syfte är att beskriva och analysera controllerfunktionen på divisionsnivå eller motsvarande och vi fokuserar vår undersökning på controllerns plats i organisationen, roll samt arbetsuppgifter. Vi har gjort en metodkombination av både kvantitativ och kvalitativ karaktär beträffande telefonintervjuundersökningen och djupintervjuerna. Vår metod är deskriptiv och vår analysmetod är analytisk induktion. Den teoretiska utgångspunkten är en av oss genomförd genomgång av litteratur och tidigare forskning angående controllers. Vårt empiriska material är insamlat, dels med hjälp av 27 telefonintervjuer, dels med hjälp av tre djupintervjuer.

Bakgrund och problem: En av de mest betydelsefulla diskussionerna idag ?r artificiell intelligens. En yrkesroll som p?verkas i takt med tekniken ?r controllers. Tidigare har denna yrkesroll beskrivits som diffus och bred, vilket har bidragit till dagens uppfattning att yrkesrollen ?r av en komplex karakt?r.

Bakgrund och problemdiskussion: Affärsstrategier syftar till hur företag skapar värde för kunden och differentierar sig från konkurrenterna på marknaden. Som ett led att göra organisationen medveten om strategin krävs en god implementering och ett förverkligande av strategin. Implementeringen blir ofta graven för strategier och den största utmaningen för företag är inte att formulera strategin, utan att förverkliga den. Controllerns huvudsakliga uppgift har länge varit att skaffa finansiell infromation som ligger till grund för beslutsfattande. Dock har forskning på senare år visat att rollen som controller i kommersiella organisationer är under förändring och att den kan komma att få en större betydelse för förverkligande av strategier i organisationer.

In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

Danmarksplass is situated just outside the centre of the city of Bergen on the Norwegian west coast. It was built in the 1930´s as a result of an architecture competition won by the prominent Norwegian architect Ole Landmark. Danmarksplass was originally meant to function as a local square, but its location next to Fjösangerveien, a road that caters for most of the through traffic in the Bergen valley today and is part of one of the main European roads, E39, would prove it difficult for that idea to prevail. Along with the ever increasing car traffic, Danmarksplass has more and more become a very busy traffic junction. Nowadays the car is the sole ruler of Danmarksplass.

This thesis describes the design of a tipping trailer, from a company?s demands andrequests to complete manufacturing documentation. The design is developed for thecompany Abexor AB in Östersund that produces tipping trailers. The product issupposed to be used by Abexors customer to transport cargos of different kinds,such as gravel, stone, dirt, etc.The work commenced with a meeting at the company where demands were set.After that a pre-study was conducted to find out what traffic rules were required forthe trailer to be allowed to be driven on roads. Similar products were examined tosee how the trailer could be designed.

A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..

Termen controller började användas i Sverige runt år 1970 och är idag en vanligt förekommande syn i platsannonser. Enligt tidigare forskning på området har controllerrollen utvecklats från att ansvara för planering, uppföljning och analysering, till att handla om att hjälpa företaget att nå sina strategiska mål genom avsiktlig påverkan och styrning. Vi har dock fått indikationer på att den traditionella controllerrollen fortfarande utgör en stor del av arbetsmarknaden och vi valde således att undersöka saken närmare. Syftet med denna studie är att ta reda på om en controller idag har samma arbetsuppgifter i verkligheten som i litteraturen samt att bidra med kunskap om företagens avsikter med anställningen av en controller. Med ett hermeneutiskt synsätt har vi valt en kvalitativ forskningsmetod.

Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.

The streetscape is a complex environment with a lot of different parts and users. If you look at the streetscapes main parts you have floor, walls, roof and furniture. The floor in the streetscape, the street, consists of the ground and the paving. It can be made of a lot of different materials with both architectonic and practical functions. The walls usually consist of the houses. They have a big influence on the streetscape depending on architecture, heights and widths.

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..
