Sannolikheter i fotbollsmatcher : -Kan man skapa användbara odds med hjälp av statistiska metoder?
Betting under ordered forms has been around for a long time, but the recent increase in Internet betting and the large sums of money that are now involved makes it even more important for betting companies to have correct odds. The purpose of the essay is to calculate probabilities for outcomes of football games using a statistical model and to see if you can find better odds than a betting company.The data contains the 380 games from the 2004/2005 season and the variables form, head-to-heads, league position, points, home/away, average attendance, promoted team, distance and final league position from previous season. After performing an ordered probit regression we only find the variable ?form of the away team? to be significant at the 5 % level. We suspect the presence of multicollinearity and perform a VIF-test which confirms this. To fix this problem we perform a second ordered probit regression where a number of variables are combined to index variables. In the second regression we once again find only one significant variable.

Thereafter, anumber of different basic concepts was retrieved and evaluated.
Validation of rumination measurement equipment and the role of rumination in dairy cow time budgets
Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high Yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.
Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi
AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.
Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :
The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.
Det nya Gustavsvik : -En studie av förnyelsen av en attraktion
Studies show that some pupils with ASD (autism spectrum disorder) can have difficulties in understanding written texts. The present study seeks to examine whether pupils with ASD differ in their reading comprehension of a factual text and a literary text. Another aim of the study is to obtain a picture of the reading habits of high school pupils with ASD, what reading strategies they use, and how they work with texts in Swedish lessons in school.The study uses texts from PISA surveys from 2009 and 2000. The factual text Varmluftsballongen (The Hot-air Balloon) was taken from the try-out for the 2009 survey and the literary text Gåvan (The Gift) was taken from the 2000 PISA survey. To gain some idea of the pupils? reading comprehension of the texts, the present study used the tasks accompanying the texts, with certain changes in the questions about the text on the hot-air balloon.
Diversifiering i lantbruksföretag : en litteraturstudie om hur utvecklingsprocessen ser ut i lantbruksbaserade företag som utvecklar nya verksamhetsgrenar
Today´s debate in farming is being focused on tourism, outdoor life and hobbies in the rural areas. This is of interest also for the general public as a way of counteracting the depopulation of the rural areas. Within the last years, the farming has become more technically advanced and hence efficient. This has led to increased production volumes and wider selection of products with lower margins for the farmer as a consequence. When the profitability is reduced, the farmer is faced with the choice of either increasing efficiency or diversification of the business.
Begomovirus susceptibility in wild Nicaraguan tomato populations
Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great Yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.
Är etiska fondinvesteringar försvarbara : vad kostar etik?
Recently, the selections of ethical funds are increased; at the same time investors with social and moral preferences have increased in the capital market. There are currently debates on whether ethical funds perform better or worse than funds without ethical criteria. This also involves a vivid discussion on whether investors know about the consequences of investing in ethical funds. Therefore, this study involves theories about the rationality and decision theory, in addition to what mainly control the investment decisions. The study also discusses portfolio theory since this is one of the underlying theories behind fund management and its development.The purpose of this study is to explain if ethical limitations in the selection of securities affect risk and return in the fund portfolio.
Flygteknik : Konceptstudie av ett obemannat flygplan
Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.
Hedgefonder : En empirisk studie om olika hedgefondstrategier och deras påverkan på avkastning
Investment in hedge funds is a relatively new phenomenon for investors compared with other forms of savings. In recent years, the interest has increased among investors in investing their money in hedge funds, given the protection against declines in the market they are aiming for. Their main purpose is to generate a high return at a low risk regardless of market trends. This they can achieve by having fewer restrictions that offer more flexible investment strategies and freer investment opportunities.The purpose of this paper is to identify how the selected hedge fund strategies have performed during the recent economic downturn. We also want to clarify the claim that hedge funds exhibit a positive absolute return regardless of what the market is performing.In order to answer the purpose of the essay and its problems, we have used a quantitative method with a deductive approach in the processing of data.

Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive Yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve Yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
