Article search occurred in the databases PsycINFO and PubMed. Nine articles were selected based on the study?s inclusion criteria.

I detta arbete undersöks hur bestraffningsmetoder för att bestraffa storleken på GP-program påverkar generaliseringsförmågan. Arbetet grundar sig på ett arbete som Cavaretta och Chellapilla gjort, där de undersöker skillnaden i generaliseringsförmåga mellan bestraffningsmetoden ?Complexity Penalty functions? och ingen bestraffningsmetod.I detta arbete har nya experiment gjorts med ?Complexity Penalty functions? och ?Adaptive parsimony pressure?, som är en annan bestraffningsmetod. Dessa bestraffningsmetoder har undersökts i samma domän som Cavaretta och Chellapilla och ytterligare i en domän för att ge en bättre bild av hur de generaliserar.I arbetet visar det sig att användningen av någon av bestraffningsmetoderna ?Complexity Penalty functions? och ?Adaptive parsimony pressure? oftast ger bättre generaliseringsförmåga hos GP-program.

The purpose of this this thesis is to evaluate the books that the Library Project "Give me five" uses accoring to their own project objective. Starting in the discussion of censorship that took place in Swedish media, the goal of the project is to defend picture books that portray child's inner and outer worlds. Some of the books are selected by librarians and some preschool teachers themselves have chosen. I have a in a thematic analysis examined if the books' themes meet the requirements of the project goals and if there is any difference on the books that preschool teachers chosen and the ones that the librarians have selected. I have in a image analysis investigated whether they have used books that challenge children's imagery, and if the books portray children's outer world.

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

The essay's aim is to create an understanding for the act; ritual, and the functions or possible functions in an organisation. Many of the functions attribute to rituals lie in the ritual's double function. A ritual can function both as a practical/functional and a symbolic act. The functionality in a ritual doing is not depending of the "symbolic meaning". The functional value exists there always.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.

This thesis concerns five Gotland Bronze Age cairns. They have been analyzed in order to compare their inner and outer burial - and building context. The analysis then forms the basis for the discussion of the similarities and differences observed. These five cairns along with the cairn Uggarderojr are presented in detail and compared. Major similarities were found between four of the five cairns.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.

The aim of this report is to give a concise description of curtain walls, what it is and why they are used. It is also a description of six different but commonly used design technologies. By giving a detailed description of the different types and there special properties, the pros and cons will be clarified. The three most interesting alternatives were selected to be included in a test, to show the best alternative from a certain point of view.The parameters are:? Environment? Cost? Ergonomics? Isolation against noise and fire? DurabilityThese are important parameters in the planning and design phase.

Granskande av ritningar, tidsplaner och kalkyler för referensprojektet Hus N i Växjö har hjälpt oss kartlägga skalväggars för- och nackdelar. Från intervjuer har vi sedan kunnat se liknelser och skillnader om vad olika yrkesfolk i samma bransch tycker, sedan därifrån dragit slutsatser. Det är inte alltid enkelt att avgöra vilken byggnadsmetod som är att föredra för att projektet ska vara kostnadseffektivt, prefabricerat eller platsbyggd. Faktorer som byggnadens konstruktion, årstid, arbetsmiljö, resurser, tid och kostnad ska ta hänsyns till.Genom att planera bättre, öka förtillverkningen, skapa en bättre samverkan mellan byggherrar, konsulter, entreprenörer, underentreprenörer och materialleverantörer, så anser man allmänt att man kan öka industrialiseringen av byggandet. Då man kan få kortare byggtider och lägre totalkostnader. .

HAFA Bathroom Group has given us the assignment to develop a standardized back panel for their bathroom cabinets. This cabinet is going to be applied to most of their current and future cabinet solutions. To this point, they have constructed unique suspensions-and back panels for most of their cabinet models. They have also been forced to pull wiring and assemble the cabinets differently because of factors like; position of the wall sockets, dimensions of the cabinets and their shapes.The company wants to distance themselves from their current solution, firstly because the cost of having manpower to design each individual suspension solution, secondly because they will save a lot of money when the manufacturing process requires a minimum of components to be constructed. As a result of this, the company can use their resources better to develop future products.The main idea is that the consumer isn?t required to change the suspension or back panel when they decide to buy a new cabinet.

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.
