The project has been performed in collaboration with Thule Sweden AB, a global leader in developing safe, simple and elegant solutions for the transportation of various types of equipment. The company has developed a new T-tRack which is telescopically, they stand mount system to connect the roof box to the roof Rack does not fit into this. Therefore, the company considered that it was necessary to have a new product that meets the requirements of the new roof Rack. They wanted a new, smarter solution would be developed. The bulk of this essay has been to find a new concept to connect the roof box to the roof Racks. The result is a saxkonstruktion that slides down the roof Rack T-profile and protected out of a puck-like housing. The product is small, simple and elegant solution.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash Rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash Racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the Rack were then determined for each inclination.

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.

The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.

Knowledge about feed Racks for feeding forages to horses is lacking. Racks for sheep and cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales with the plastic and net still on, can bring on a lot of different problems. The opportunity to control the hygienic quality is small and feed losses can be high. The purpose of this experiment was to investigate how the eating behaviour and consumption of horses were influenced by feeding Racks of different constructions. Feed losses and changes in chemical composition of the forage were also studied.

During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Radio Frequency Identification (RFID) är en teknik som enligt många utsetts till framtidens teknologi inom Supply Chain Management. Detta då RFID, utan involvering av människan och utan behov av fri sikt, på distans kan utföra effektiva identifieringar av objekt. Det har emellertid, genom forskning, uppmärksammats problem med RFID och dess i vissa fall bristfälliga ändamålsenlighet inom logistiska sammanhang. Utifrån de möjligheter och hot som RFID innebär, har detta examensarbete kritiskt undersökt hypotesen: "Logistiska RFID-implementeringar är lönsamma och tillförlitliga". Analysen grundar sig på ett arbete genomfört vid Volvo Car Corporation (Volvo) i Göteborg och Olofström, där ett pilotförsök med RFID- utrustning för lång avläsningsdistans installerats och processeffektivitetsstudier fullföljts.

The purpose of the project was to design an electric bicycle to offer thetarget group youth an attractive alternative to mopeds. The basis for theproject was user studies in which young people were interviewed andobserved in their daily environment.The project resulted in a product, designed with the focus of integratingthe battery to the shape, to create a wholeness that is simple andintuitive.!The product is easy to use and operate, with an automatic transmissionengine.! A smart modular system allows the user to choose design withmudguards, rear Rack, or without. The battery design is based on "cradleto-cradle" to maximize the battery life and minimize environmentalimpacts.It was very fun and rewarding to have the opportunity to present theresults for the youth who showed great interest in the product.The project was conducted in collaboration with Designit and Cycleurope..

The basis of the study lies with a newly patented gearbox by cardiologist and inventor Stig Lundbäck. Stig founded CorPower Ocean AB to further develop the gearbox to be used in a wave energy device. The purpose of this project is to develop a concept of a lifting system with CorPower Oceans gearbox that is more energy efficient than a hydraulic lifting system. The goal is to use technology from CorPower Oceans gearbox inversely to perform heavy lifting as an alternative to hydraulics. The project is limited to applying the gearbox and gear Rack on a forklift with a lifting capacity of ten tons.The main tool in this project will be the product development process Systems Engineering where only the most relevant parts will be used to develop a concept.

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike Rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.

Under fem veckors tid har jag utfört mitt examensarbete på Facebook Data Center i Luleå. Målet med arbetet var att installera ett internt nätverk som skulle ersätta ett annat internt nätverk. Bakgrunden till arbetet är att nätverket som redan existerade i datacentret (innan bygget överlämnades till Facebook i Luleå) hade en omodern nätverksstruktur. I arbetet avsattes tid till inläsning av plattformarna för routrar och switchar. Dessa enheter monterades senare upp i respektive Rack.

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.
