A risk analysis of moose close to roads
For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.
Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell
An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
Attityder på byggarbetsplatsen : En studie om den psykosociala arbetsmiljön
Byggbranschen är en olycksdrabbad bransch. År 2007 skedde 3114 olyckor och 16 dödsfall. Många teorier och förklaringar har gjorts i olika publikationer som visar på problemet. En oro finns inom branschen som riktas mot den höga olycksstatistiken. Det kan vara svårt att lokalisera de brister som orsakar olyckor och ibland kanske man blundar för viktiga faktorer.
Med för hög musikvolym hör du inte farten
Att tidsperceptionen är påverkbar har tidigare påvisats. Studien syftar till att undersöka huruvida tidsperceptionen påverkar fartperceptionen, med hypotesen att när interna taktgivaren går snabbare uppfattas farten som lägre. 28 försöksdeltagare fick under fyra betingelser (Lugn, Stressig, Egen musik och Tyst) utföra tids- och fartestimationer under bilfärd. Inga signifikanta resultat påvisades ifråga om vare sig tidsperceptionen eller dess inverkan på fartperceptionen. Däremot skilde sig prospektiv estimation av medelfart åt beroende på betingelsen.
Arbetet med iPad i förskolan : En undersökning om hur man arbetar med iPads i en mellanstor kommun
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.
East Side Story, a West Side Story? : En Kritisk Diskursanalys av Afghanistankriget i Västerländsk Nyhetspress
The purpose of the study is to expose how the US newspaper New York Times and the Swedish newspaper Dagens Nyheter mediate the war in Afghanistan. Furthermore a comparison is done to map out possible differences and similarities. To fulfill the purpose of the study a critical discourse analysis has been used. The results have shown both differences and similarities between the newspapers. The main conclusions are tendencies of correspondence with previous research and theoretical base, such as the furtherance of elite sources, the promotion of the national political agenda and the national identity and an obvious construction of us and them..

Kommunikation, uppföljning och tidsplanering inom detaljprojekteringen : Hur projekteringsprocessen kan effektiviseras med små medel
Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.
Konstruktion av sök/räddningsrobot
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Försvarsenhetens arkiv : Examensarbete på länsstyrelsen i Södermanlands län
The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..
Sjuksköterskans upplevelser av patienter med psykossjukdom och deras delaktighet i den psykiatriska öppenvården
Several studies show that the clinical reality in psychiatric care does not correspond to the demand of consumer participation from a variety of policy documents that has been produced recently. Studies also show that there is a lot to do in improving, patients with sever mental illness, becoming more involved in their own care. The nurse has a central role in this work. The Norwegian nursing theorist Jan-Ka?re Hummelvolls holistic, existentialistic model for psychiatric nursing were used as theoretical ground.The aim of this study was to examine how nurses in psychiatric outpatient units, caring for patients with psychotic disorders, experiences consumer participation.Qualitative phenomenological method was used.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?
In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.
