Analys av en metod för att extrahera generella regler från multipla nät

Rapporten som följer är en analys av en metod som genererar regler från neurala nätverk. Metoden heter VI-Analysis (Validity Interval Analysis) och är framtagen av Sebastian B. Thrun [Thrun]. VI-Analysis arbetar på det sättet att det neurala nätverket ses som en svart låda där endast de inputvärden och outputvärden som finns i nätverket används som underlag när regler ska genereras. Dessa inputvärden och outputvärden kommer sedan att få tillåtna intervall av VI-Analysis.

Kvantitativ RT-PCR-analys för detektion av pigmentrelaterade transkript i hårrötter från hund :

Malignant melanoma represents 4-7% of all canine neoplasms and they are the most common malignant tumors of the oral cavity and digits. These tumors are often aggressive and metastasize quickly. To date there is no effective treatment and survival times are short. Most dogs are euthanized due to complications caused by metastases. Melanin pigment is a hallmark of melanomas and is usually present in large amounts in these tumors.

Den ansiktslösa rösten : Analyser av Jenny Holzers verk och en studie i den konsthistoriska bilden av henne.

Denna uppsats tittar närmare på fyra verk av Jenny Holzer. Hennes konstnärskap jämförs även med Guerilla Girls. Huvudmetoden utgörs av bildanalyser och jag presenterar också tolkningsmöjligheter utifrån ett genusperspektiv. Utöver detta har jag med en konsthistoriografisk undersökning fått fram hur den generella bilden av Holzer ser ut..

Effekter av befintliga och eventuella framtida läkemedelsbehandlingar på morbiditet och mortalitet hos patienter med hjärtsvikt.

Background:  Heart failure is a multidimensional phenomenon with high mortality. Heart failure is treated with angiotensin converting enzyme (ACE) - inhibitors or angiotensin receptor blockers (ARBs) that counteract neurohormonal stimuli that occur in heart failure, as well as providing vessel dilatation, which reduces symptoms and the need for hospitalization and increases survival. Despite this, only about 50% of heart failure patients survive 6 years after diagnosis with drug therapy, and as heart failure is increasing globally, due to improved care and treatment and increasing life expectancy of the population, there is a great need for new drugs such as LCZ696 that acts by dual inhibition of the renin - angiotensin - aldosterone system and neprilysin inhibition.Objective: The aim of this literature study was to evaluate the efficacy of current treatment and possible future treatments on mortality and morbidity in heart failure patients.Results: The examined articles show that treatment with ACE inhibitors in patients with symptomatic heart failure reduces the risk of total mortality by 16% over 3.5 years, reduces all-cause mortality or hospitalization due to heart failure with NNT (number needed to treat) = 10.4 over 3.5 years and increases median survival by 9.2 months over 12.1 years in patients with asymptomatic heart failure. Treatments with high-dose ACE inhibitors reduce mortality and hospitalization because of cardiovascular causes and hospitalizations from any cause by NNT = 30 over 3 years. Beta-blockers reduce sudden death and total mortality and cardiac death or non - fatal myocardial infarction with NNT = 38 and NNT = 23, respectively, over 12 months.

Vad behöver växter för att växa och överleva? : En studie om förskolebarns tankar om växters behov

The purpose with this study was to examine what kind of knowledge children in preschool have regarding what plants are, and what plants need in order to grow and survive. By means of qualitative interviews I have let 12 children in the ages of 3 to 5 years answer questions regarding the subject.From the results it is obvious that the children in the early age groups already have some knowledge of what a plant is and can also mention a few basic factors for a plants survival. In addition, the results show that their knowledge increases with the childs age and that the conversations become more distinct with more resulting questions the older the children are.Keywords.

Hav och Strand : stenteknologi och marin anpassning på Gotland under Senboreal/Tidigatlantisk tid

The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..

Hur doftar parfymreklamen? : En Studie i hur man kommunicerar doft genom bild i parfymreklamen

With the help of image analysis and scent theory, we have made an analysis that explains how the perfume smells in advertising. There are many different factors that play a role in our perception of smell by image. We have found that using the connotations we can get a sense of the scent. What helps us along the way, the colors, the women and the environment. From this one different conclusions are mad and we create a scent sensation..

Population and management models for the Swedish wild boar (Sus scrofa)

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

I BRÄNNPUNKTEN: Samhällsekonomisk utvärdering av arbetsmarknadsåtgärder. Illustrerad med hjälp av Brännpunkt i Kävlinge 2002-2005

The purpose of this essay is to examine cost-benefit-analysis as a method of evaluation of labour market policy. To illustrate the possibilities and difficulties of the method chapter four contains a partial cost-benefit-analysis of the results of a labour market project in Kävlinge. The questions this essay strives to answer are the following: What possibilities and difficulties do cost-benefit-analyses entail? How would one conduct a cost-benefit-analysis of the project in Kävlinge?The method used in this essay is mainly a literature study of cost-benefit-analysis of labour market programs. The labour market project Brännpunkt is used as an example in a partial cost-benefit-analysis.The applied cost-benefit-analysis of the Brännpunkt project in Kävlinge shows that it is possible to calculate the profit for the society as a whole, given that the necessary information is obtainable.

Shareholder value - The American way and the Swedish game to play? : En studie om ideologisk förändring i svensk bolagsstyrning

Shareholder value has its origin in the American corporate governance system and has been the subject of great debate over the last few decades. The proponents claim that it creates economic efficiency while the critics argue that maximization of shareholder value jeopardizes the long term survival of companies. However, the debate in Sweden already seems to have forgotten the question of how embedded the ideology really is and what´s leading its way. This study show that shareholder value has developed and been established in Swedish companies between 1995 and 2005. The study has found evidence that suggests that the development can primarily be linked to board networks and international exposure.
