Simulering av översvämningar i Byälven
Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.
Vilka statsfinansiella effekter erhålls vid ökad produktion av förnybar energi?
BackgroundThis paper is based on an issue raised by the organization Energigas Sverige, which together with the Ministry of Finance has posed the question about the fiscal impact of an increase in biogas production. Since the fiscal effects of an increased biogas production are both positive and negative, due to reduced use of fossil fuels, we want to investigate this further.PurposeThe purpose is to describe and explain the obtained fiscal impacts of an increased biogas production and based on our problem: ?What are the obtained fiscal effects caused by an increase in biogas production?? we could see the following fiscal effects: positive impact on employment, increased revenues of social security contributions and income taxes, reduced unemployment costs and reduced tax revenues on fossil fuels. These effects are summarized in a negative tax revenue of 2,6 billion SEK. Along the summarized negative effect we also accepted one of the two prepared hypotheses, which stated that an increase in biogas production leads to a negative fiscal impact. Design/Methodology/ApproachWe have chosen to work from an Anglo-Saxon scientific tradition and furthermore, we have a positivistic approach when we want to explain the relationship between cause and effect of an increase in biogas production and the following fiscal impacts.
Genetisk studie av inavel och fertilitet hos hund :
Inbreeding, the mating of related individuals, has been the one dominating breeding strategy for dog breeders during the last 200 years. However, its negative effects on fer-tility and other fitness traits, a phenomenon called inbreeding depression, have been ignored in the quest of perfect unity in conformation or performance. The purpose of this study was to test the hypotheses that litter size is reduced as a consequence of in-breeding, affected by both the inbreeding coefficient of the dam and the litter and that a rapid increase in the inbreeding coefficient affects litter size more than a slower rate.
Data were collected from the Swedish Kennel Club registry of origin. Breeds included in the study were the Bernese Mountain Dog, the Cocker Spaniel, the Golden Retriever, the Rottweiler and the West Highland White Terrier.
Studier av mjölkbarhet automatiskt mätt i mjölkningsanläggningar :
Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.
De sociala medierna och rättssystemet
The main purpose is to investigate the main fea-tures of the discourse in the social medias about the legal view on cimes and criminals. The special questions that are investigated are:1) What specific features characterize the discourse in the social medias?2) What are the legal restrictions for the freedom of speech on the Internet?3) What attitudes can you find among lawyers towards the discourse in the social medias?4) Are there grounds for presuming that the discourse in the social medias can effect the judgement in a special case? .
En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur
This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.
I morgon blir det börsfall! : En studie om hur olika börser påverkar varandra i fördröjning
SammanfattningTitel: Imorgon blir det börsfall! En studie om hur olika börser påverkar varandra i fördröjning.Seminariedatum: 28 maj, 2012Ämne/kurs: FEK 61-90 Kandidatuppsats i Corporate Finance, 15 poäng Författare: Stefan Koch, Malin Molin Handledare: Hans MörnerExaminator: Kent SahlgrenNyckelord: Anomali, anomalier, veckodagseffekt, måndagseffekt, index, korrelation, S&P 500, OMXS 30, effektiva marknadshypotesenSyfte: Att undersöka ifall en eventuell anomali på det svenska OMXS 30 indexet eller det amerikanska S&P 500 ger en effekt på nästföljande dag på det motsatta indexet. Om en veckodagseffekt kan påvisas och den fördröjda korrelationen mellan indexen är tillräckligt stark kan metoden användas för att generera överavkastning. Metod: Vi använder oss av en kvantitativ ansats för att med hjälp av statistiska metoder svara på vår problemformulering. De metoder vi har använt är hypotestestning av medelvärden med ett z test, beräknat korrelationskoefficienten mellan de två indexen och utfört en multipel regressionsanalys med dummyvariabler.Slutsats: Genom vår analys kom vi fram till att en veckodagseffekt inte kan påvisas på någon av de två undersökta indexen. En korrelation kunde finnas mellan de två indexen, däremot går det att ifrågasätta om korrelationens styrka är tillräckligt stark att handla utifrån. För att generera överavkastning krävs dessutom att den extra avkastning som genereras med hjälp utav vår metod med korta aktieaffärer överstiger den eventuella transaktionskostnaden som uppstår vid aktiehandel, något vi starkt betvivlar att den gör..

Problematik vid analys av fastighetsbolag efter införandet av IFRS
The study describes the problems with analysis of real estate companies after the introduction of IFRS. With the introduction of IFRS (2005) and specially IAS 40 the real estate companies get the ability to appreciate its real estates to real value. With the difference in the accounting, grows the question if it has become some differences for analysts with analysis and valuation of real estate companies. We also look into how well this new standard effect the real estate companies from the view of the accounting quality and its characteristics..
Bostadsbranschens väg in i upplevelseekonomin : Kan fastighetsmäklarens arbete omvandlas till en säljande upplevelse?
The civilization has taken a step from the industry society to a service oriented culturewhere the physical differences between different products have decreased in value for the customers. The differentiation is more about senses, esthetical symbols and design. Modern economy is more and more focused on consuming and produce dreams and lifestyles. Maybe are we ready to face a new era; the society of experiences?Can the trend that is striving towards experiences really be adapted to all markets? This question started our quest to see how the real-estate market would be able to be adapted to this new economy.
Hårdhetsvariation i grundvatten längs Badelundaåsen mellan Leksand och Avesta
Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.
Jämförelse av icke-kryptografiska hashfunktionerför användning i hashtabeller
This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.
Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :
Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety.
One of the regulation systems includes the short chain fatty acids produced during feed
degradation in the rumen. Starch can be digested either in the rumen where short chain fatty
acids are produced or in the small intestine where glucose is the end product. Since glucose
does not have the same effect on satiety that short chain fatty acids have, the site of starch
digestion might be an important factor that affects feed intake and milk production. The aim
of this study was to investigate the effects of site of starch digestion on feeding behaviour
(feed intake, consumption time, and eating frequency) and milk production.
Because feeding behaviour is closely connected to the cows? environment, the study also
included observations of behaviour.
Three different feed rations were compared.
Gymnasieskolans projektarbete och dess effekt på skolkande elever : En studie kring skolkande gymnasieelevers uppfattningar om kursen ?Projektarbete 100 p?
In this study I have brought up what pupils within vocational training, with focus on upper-secondary school have apprehended about the course ?Projektarbete 100 p? (Project job 100 point). In my analysis I interviewed twelve pupils from upper-secondary school who had 20 % or more truancy during their three years of studying in upper-secondary school and achieved a result to these pupils had problems with absenteeism then primary school. The pupils agreed about the school?s existence but they need schools of practical type.
Zakrisdal : Område i förvandling
Zakrisdal and the west coast region of Karlstad was at one time a protected area where the ammunition factory AmF Zakrisdal 1941-1994 was situated. This factory manufactured explosives for the Swedish armed forces and for export. In this context it is an interesting paradox that the production of ammunition, mines and armorpiercing grenades for more than 50 years has preserved the environment surrounding the factory.The factory is now gone and the production is moved to Karlskoga. Plans are being made to build housing for 3-4000 residents and other enterprises within the area. The area now stands before yet another change, most likely the most profound to date.The inspiration for this work comes from the economic historic Jan Jörnmark.
