Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.

When the purpose is to create an illustration plan for a new neighbourhood there arelots of things to think about. In this report follows a description of the three differentplan modells SCAFT/TRÅD, garden city and ekological planning. SCAFT is aplanning model that were used in the 1970s. It contains proposals how to make thetraffic enviorment safer. TRÅD replaced SCAFT in 1982 and it contains also adviceshow to make the traffic enviorment safer.

Examensarbetet är en studie i felsökning och optimering av IP-telefonisystem i ett befintligt nät. Här beskrivs hur ett IP-telefoninät bör byggas och konfigureras för optimal prestanda utifrån Ciscos rekommendationer. Det aktuella nätet är IT-Partners nät som drivs av Nortel när det gäller IP-telefonidelen. I dagsläget har de vissa återkommande problem när det gäller IP-telefonin t.ex. att samtalet bryts då och då.

Denna uppsats är skriven inom ämnet Företagsekonomi och omfattar 15 högskolepoäng på C-nivå på Institutionen för ekonomi vid Sveriges lantbruksuniversitet. Tanken bakom vår uppsats är att ge en bild av vad controlled traffic farming (hädanefter förkortat CTF) är, samt om odlingstekniken kan ge bättre lönsamhet i svenskt lantbruk. Förhoppningen är därmed att uppsatsen skall ge en grundförståelse inom ämnet. CTF innebär att permanenta körspår anläggs och att all fälttrafik sker i dessa körspår. Följderna av detta blir således att åkermarken mellan körspåren övergår till att vara mer lucker, eftersom lantbruksmaskinernas markpackning koncentreras till körspåren. Markpackning är ett av de stora problemen i dagens jordbruk och målet med CTF är att öka lönsamheten genom högre fältavkastning till följd av bättre markförhållanden för grödan. Studien utgörs av en jämförelse mellan konventionell plöjningsfri växtodling och odling med systemet CTF.

This report discusses developing a software log tool for analysis of industrial processes. The target was to develop software that can help electro Engineers for monitor and fault finding in industrial processes. The tool is called PLS (Process log server), and is developed in Visual Studio.NET Framework 2005. PLS works as a client with Beijer Electronics OPC Server. The program is able to read data from PLC (Programmable Logic Controller), trough the OPC Server.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Whiplash is a bodily injury, where the person that is injured is subjected to force towards the neck, mainly in traffic accidents. Even low speed accidents can cause severe damage due to the complicated muscle and nerve structure of the neck. Symptoms range from neck aches and headaches to numb fingers and this makes the Whiplash injury difficult to diagnose. Whiplash is also a treacherous injury due to the fact that the symptoms can not be objectively verified. The principal symptom of the injury is pain, which is to its nature highly subjective.

Målet med uppsatsen är att åskådliggöra vilka fördelar, nackdelar och effekter användarbaserad systemutveckling har för den administrativa delen av en organisation. Intervjuer har gjorts med en chef och en controller på ett större svenskt företag samt med en expert inom området för användarbaserad systemutveckling. Undersökningen visar att fördelar som ges vid användande av användarbaserad systemutveckling är t.ex. att organisationen och individen blir mer produktiv, får en mer flexibel miljö att arbeta med och blir mindre beroende av konsulter. Nackdelar har visat sig vara att organisationen kan försätta sig i en situation där de blir beroende av den person som har utvecklat ett specifikt system och kvaliteten på underhåll kan även försämras när användarna utvecklar själva.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

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.

The primary aim of the current study was to gain increased knowledge about drivers' risk experiences. The study was based on questionnaires answered by 30 private drivers and 30 bus drivers, with 50% men and 50% woman in each group. The study revealed no differences, either between men and women drivers with regard to their experience of risk, or between the groups of private and bus drivers. Gambling is common within the private drivers group. Mistakes are common in all groups.
