Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem
In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.
Renen och nötkreaturet, en jämförelse mellan två olika typer av idisslare :
The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.
Analys och reducering av kapitalbindning i lager : Analysis and reduction of capital tied to existing stock
Detta arbete genomfördes under 10 veckor vårterminen 2009 på Bigso Box AB i Nybro,ett företag som tillverkar förvaringslösningar för hemmet och har stora kunder somIKEA.Bigso vill ha hjälp med att undersöka materialflödet och de lagernivåer företaget besitteri sin producerande fabrik i Litauen. Främsta målet med arbetet var att minskakapitalbindning i färdiga produkter samt på halvfabrikat i fabriken. Då Bigsos störstakund IKEA ställer extremt höga krav på leveranstider och företaget ibland hamnar eftermed ordrar önskar Bigso även att genom en större kontroll av materialflödet och genomatt hålla rätt lagernivåer även komma till rätta med detta problem..
SFINX ett integrationsprojekt : ur deltagarnas perspektiv
Abstract This paper is to examine a specific integration projects by the name of SFINX, the participants' perspective. We chose to highlight three themes that concern the analysis what the participants thought about the content / efficacy, effectiveness and efficiency analysis, which means what the participants thought could be improved in the project. What emerged in our study is that research shows that Swedish education with professional orientation and integrated practice is a key factor for migrants to get into the Swedish labor market. And that Sfx teaching has been implemented in several places with good results. SFINX is also a Sfx project but is addressed to engineers.
Utvärdering - till vilken nytta? : En studie om hur utvärderingar användas och vad som gör dem användbara
Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.
The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems
Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.
Review of the litterature and an attempt to evaluate intake levels of iodine and selenium in dogs with and without lymphocytic thyroiditis
The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.
The importance of Yeheb (Cordeauxia edulis) for Somali livestock production and its effects on body tissues when fed to Swedish domestic goats
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.
Ökad resurseffektivitet i kraftvärmesystem genom säsongslagring av värme
Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

Utvärdering av den nationella söktjänsten LIBRIS
LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.
Kan geografiska informationssystem effektivisera skapandet av beslutsunderlag?
Villkoren i dagens samhälle förändras snabbt och miljön som beslutsfattare måste hantera blir allt mer komplex, detta samtidigt som tiden för att fatta beslut krymper. För att beslutsfattare ska klara detta kan de ta hjälp av verktyg. Vi har undersökt om geografiska informationssystem (GIS) är ett verktyg som effektiviserar framtagandet av ett beslutsunderlag när problemet är geografiskt relaterat. Undersökningen har genomförts som en fallstudie på fyra olika organisationer där vi jämfört processen vid skapandet av ett beslutsunderlag före och efter införandet av GIS i organisationen. Slutsatsen vi drar av vår undersökning är att geografiska informationssystem effektiviserar framtagandet av beslutsunderlag när problemet är geografiskt relaterat..
