Comparison of two methods for evolving recurrent artificial neural networks for
n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.
Genetisk och etologisk analys av vallningsbeteende hos border collie :
The ability of a dog to perform some kind of practical work, for example hunting or herding, depends among other things on its behavioural characteristics. In animal breeding it is not always easy though to select for behavioural traits. It may, for example, be difficult to identify traits that are not only heritable but also of importance for the dogs' ability to perform the practical work of interest. Moreover, it is often difficult to accomplish accurate measurements of behavioural traits. When selecting dogs for breeding, it is usually preferable to evaluate them using an objective and standardized bahavioural test, rather than results from field trials.
Svenskt projektledarskap i multikulturella grupper : är en anpassning nödvändig?
Background: Having chosen to take a degree in international business, we have had many opportunities to meet people from different cultures. These encounters have, we believe, made our lives richer, but they have not always been problem-free. When different cultures come together, the differences inevitably become apparent. Being among friends, one can maybe laugh at these differences or it may be a good opportunity to get people to talk to each other, taking the time to explain why they do things a certain way. Being at work and experience these differences might not at all have the same ice-breaking effect - rather the opposite sometimes.
E-böcker ett nytt sätt att läsa. En undersökning om digitala böcker i folkbibliotek.
The main purpose of our thesis is to discuss the subject e-books from a Swedish public library perspective. The aim of the thesis is to locate and analyse statistics in regards to lending electronic books in public libraries. With this background a text analyse have been done, which views different arguments about e-books. We have studied the current statistics about lending e-books to the public users, the statistic material was gathered from the two main providers of e-books, eLib and E-biblioteket. With this statistic report as a background, arguments from scientists, journalists and users of e-books have been studied.
?Om man börjar från början?. Litteracitetspraktiker i flerspråkiga familjer med små barn.
The aim of this master thesis is to investigate how parents? in multilingual families perceive language learning and reading for young children, and how their practice of this can be understood in relation to their language situation and cultural background.This study focuses on the interaction between parents? and young children in the light of the literacy practice. Important concepts such as early childhood literacy and family literacy have been used to study language, culture and literacy practice as phenomena that interact. The theoretical framework is a sociocultural perspective. Through qualitative interviews with seven parents?, it was found that multilingual families have a strong ambition for their children to learn all the languages spoken in the family.
Konstruktioner av kvinnor med utländsk bakgrund : En intersektionell studie av debatten om äldreomsorg och etnicitet i populärvetenskapliga tidskrifter 1995-2008
This paper aims to examine how the construction of women with foreign background is visible in the Swedish debate on elder care and ethnicity. The subject is interesting with regard to the existing discriminating conceptions about ethnicity and how the living conditions of immigrant women are med scarce in the Swedish research field. It is also a relevant topic in light of the incipient crisis of the Swedish eldery care. The examining of how several axes of power interplay to construct the women is rendered possible through an intersectional perspective. This requires of the study to relate to the concept of category, and in this paper I have chosen an intercategorical approach.
Datorer i förskolan - barns nya kultur : barnvakt eller ett pedagogiskt hjälpmedel
In this essay I have chosen to explore how computers are used in preschools. The study was done as a survey. How does preschool seize the children´s culture? In today´s society ICT and computers are a big part of children´s everyday life and reflects on their upbringing.Since I am using computers as a pedagogical tool in teaching the children at my preschool, I find this topic interesting to explore.Are the teacher´s using computers for an educational purpose with the children at preschools or are they using it in other ways?Do the teachers think they have the required knowledge to computers usage in teaching the children in a pedagogical way?What is the teacher´s attitude towards computers in preschool?The essay starts with a introductorial background section where I talk about my own experiences of using computers with the children in my preschool, and then referring to the society then and now, school law, curriculum, teachers' computer skills, media situation amongst children and young people, computer use in preschools/schools and health effects. I have composed a survey based on the answers of 50 teachers in 30 different preschools and in nine different municipalities.The result of the survey is reported and concludes with a part of discussion, where the results are put up against the introductorial background section.
Hepatit E - en zoonos?
Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.
Laserskuren intarsia : ett komplement till äldre intarsiatekniker
The purpose of this report is to explore how modern technology can work againstolder craft techniques. The focus of the research will depend on what conditions areoptimal for cutting marquetry with laser technology. In my work I account for thehistorical background of the various techniques and then through own practical testsexamine whether the laser technology can complement the traditional techniques..
Folkbibliotekariers användning av sökverktyg på webben i referenstjänst
The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.
Könsstympade kvinnors möte med västerländsk vård : En systematisk litteraturstudie
Background: Female circumcision or female genital mutilation is a tradition that is carried out mainly in Africa. The intervention refers to that part of- or all of the girl?s external genital organs are removed. Aim: The study's purpose was to highlight the consequences of female circumcision in the encounter with western health care.Method: A systematic literature reviews was performed as a method. Twelve articles were selected for the study and these were sought in Chinal, PubMed and PsycINFO. Analysis and interpretation was done according to qualitative content analysis, inspired by Lundman and Granheim.
Barn med 22q11.2 deletionssyndromet ? hur hör de?
The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.
Introduktion av division för alla - en learning study i åk 3
My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.
TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis
Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .
Unga ledares ledarskap - en kulturell fråga
Culture is seen as an abstract phenomenon, not easily defined. It is cathegorized as something that affects every person, though it is seldom described how. This study adress how culture, in the form of basic assumptions and accepted behaviors and ways to think affected how young coaches formed their leadership under the influence of their organization. The possible implications for the importance of knowing about ones culture in an organization affect both the recruitment process in organizations and what the organization stands for and what is conveyed through values and ways to act in the organization. The purpose of this study was, through the use of semi-structured interviews with young coaches and organizational leaders and a review of policys, to get the perspective and experiences of young coaches regarding cultural influence on their leadership.
