Ute och cyklar? : på jakt efter en metod att mäta upplevelse
Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Analys av nivåproblematik i dränagetank på Ringhals 1
The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

Implementering av tablets inom drift och underhåll av vägar : En utvärdering med förbättringsförlag
Implementeringen av tablets ämnade för inspektioner inom drift och underhåll av vägar har studerats och utvärderats med målet att fördjupa kunskaperna inom drift- och underhållsbranschen och skapa effektivare arbetsmetoder som gynnar alla byggprocessens parter. Examensarbetet är utfört hos Peab på deras anläggningskontor i Sundsvall och implementeringen har ägt rum på deras driftområde Sundsvall som består av cirka 122 mil statlig väg där Trafikverket är beställare. Genom litteraturstudier, tester av tableten och deltagande observationer så har tabletens användbarhet och utvecklingspotential analyserats och slutsatser har dragits för att ge Peab feedback på deras innovation med ett antal förbättringsförslag. Utvärderingen blev ej fullständig då Peab inte hann införa tabletsen inom vägdriften innan de 10 veckorna för examensarbetet var avslutade. Att använda tabletsen inom vägdriften kommer att effektivisera inspektionerna med dels digital dokumenthantering och det viktiga införande av GPS positionering i de fordon som utför inspektionerna. Detta kommer bli mycket smidigare än den tidigare arbetsmetodiken där i stort sett alla processer innefattande mycket onödigt pappersarbete. Peab rekommenderas fortsätta att se utvecklingsmöjligheter med tabletsen inom andra områden av vägdriften samt fullfölja utvecklingen av tableten för att få en användbar produkt. .
IT system för vägtransporter och tillhörande terminalverksamhet
We have chosen to write our thesis within a transport company. The work was carried out at DHL activities in Uppsala. DHL is one of the leading transport companies worldwide. Our interest lies in more efficient and advanced transportation and terminals, as globalization and new trends require effective solutions.The aim of our work is to explain the need for information technology applications in road haulage and associated terminal operations. Furthermore, we analyses terminal and applied information technology.
Kan grad av degenerativ hjärnsjukdom prediceras med hjälp av mått på kognitiv försämring?
Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.
Bättre passform på blusar - ett examensarbete i samarbete med Ka of Sweden
Arbetet gjordes i samarbete med Ka of Sweden där uppgiften varit att framställa enbättre passform för blusar i vävt material. Den nuvarande passformen saknar en brabystanpassning och har liknande ärmhål bak och fram. Jag valde att arbeta fram denteoretiska delen först och sammanställa måttlistor för att sedan arbeta fram denempiriska delen med konstruktioner, avprovningar och färdigt första prov.Resultatet av mitt arbete blev mycket bra och det har varit kul att få arbeta mot ett företag.The work was done in collaboration with the Ka of Sweden where the task was to produce a better fit for the blouses of woven material. The current fit does not have a good bust adjustment and have similar armhole front and back. I chose to work out the theoretical part first and compile lists of measurements and then work out the empirical part of constructions, fittings and finished the first sample.
Säkrare arbetsmiljö med traktorer i vårbruket :
By doing this thesis I want to open up farmers and tractor drivers mind to see that there is
several risks with their work. There is a number of risks that everybody probably already
know about, and hopefully I will, with this work, help them to see a lot more risks, to make
them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of
Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward
to.
Reglering av veka strukturer med multipla sensorer
In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.
Kartläggning av rapporterade olyckor med djurtransporter i dagspress i Sverige
When farm animals are transported there are several factors that can affect their welfare. If the vehicle has an accident the welfare of the animals transported will probably be compromised.
The aim of this study was to make a survey of accidents with animal transportation vehicles in Sweden. The survey included the number of accidents from January 2000 to May 2014, the cause of the accidents and how the animal welfare was affected by the accident. The authorities which were likely to have reports about accidents involving animal transports were contacted. There were no collected records about transportation accidents and the authorities referred to eachother for information.

Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Optimerad lagerhantering
Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.
Att göra en livsstilsförändring : Från kriminell till icke kriminell
The aim of this study was to investigate factors that ex-criminals believe have been of importance to them when they decided to leave a lifestyle of criminality behind. The study was based on eight semi-structured interviews with informants who had committed various forms of crime. Common to all informants is that they are now members in the Swedish association KRIS (In English: CRIS, Criminals Return Into Society), living a life without crime. The stories of the informants have been analyzed on the theoretical basis of social ties, the exit process, role loss, motivation and the life course perspective. Our study showed that the informants have been affected and motivated by various life events that could be identified and pin-pointed during the interviews.
