Utvecklingen av förbandsmetoder är viktigt för att utveckla konstruktionslösningar. Under det senaste decenniet har forskning på limmade förband utförts, främst på inlimning av stålstag och plattstål i limträ. Förhoppningen är att spänningen ska fördelas jämnare i förbandet och att brott ska kunna undvikas. Hypotetiskt sett skulle det kunna göra knutpunker utan synliga förband möjliga vilket även skulle gynna arkitekternas önskemål.Genom en sammanställning av tidigare forskning dras en jämförelse mellan testresultaten och en antagen knutpunkt som belastas av egentyngder och variabla laster. På så sätt kan limmets kapacitet konkretiseras.

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

Inom styr- och reglerteknik är hantering av larm en viktig fråga, speciellt då fastighetsbranschen mer och mer börjat automatisera driften av fastigheterna. Det finns ett antal system på marknaden som erbjuder larmdistribution via en mängd olika transportsystem. Syftet med projektet är att undersöka om det finns alternativ till dessa som erbjuder mer flexibilitet, samt att designa en prototyp till ett system som använder denna alternativa metod. Två befintliga system analyserades och en kravspecifikation baserad på analysen upprättades. Utifrån denna designades en prototyp som sköter distributionen över Internet och en enkel implementation av en del av designen har gjorts.

For many people, a good game is synonymous with good graphics. One thing that is often forgotten, is that the graphics only makes up one part of the games. An aspect of the games that is far to often forgotten, is the game?s content and ability to tell stories. Through analyses of the games of the Zelda series, the development of content and storytelling aspects of computer- and video games, since the later half of the 1980:s and up till today, are examined..

Syftet med detta arbete är att undersöka A-ljudteknikers lyssningsnivåer i förhållande till konsumenters lyssningsnivåer. Undersökningen av konsumenternas lyssningsnivå sker i konsumenternas hemmiljö, och undersökningen av teknikerna sker i kontrollrumsmiljö. För att arbetet ska vara så nära verkligheten som möjligt återspeglar testmaterialet programutbudet från SVT. Testmaterialet är producerat i formatet Dolby Digital 5.1. Studien visar att skillnaderna i lyssningsnivå mellan konsumenter och ljudtekniker är 8,5 dB.

In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..

The purpose of this project was to develop an interactive toy concept. A toy capable of reacting and expressing emotions like happiness, sadness, anger or love. And capable of developing its character with use.The initial questions was, how do I create interest, understanding and affection between a digital product and its user? How should the interaction be made?During the course of the project the search has mainly been for something that does not base its shape and interaction on likeness. Forexample likeness to humans or pets.I have created a toy concept called iio.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

Denna studie undersöker hur lärare arbetar med kartor i skolan och hur elever uppfattar användandet av kartor, både i skolan och i vardagslivet. Hur lärare uppfattar förändringen i mötet med kartan genom bytet från Lpo 94 och Lgr 11 kommer också att belysas. För att få svar på dessa frågor har åtta stycken intervjuer av lärare på högstadiet samt fyra fokusgrupper innehållande fyra elever styck genomförts. I intervjuerna uppger lärarna att det idag finns en bristfällig helhetssyn gällande kartan hos eleverna, fokus ligger ofta på ett litet område. Lärarna anser att denna utveckling inom ungdomars kartuppfattning påverkas av dagens teknik, som till exempel GPS där fokus ligger på start- och slutpunkten.
