De dömdas öde : en rättsmedicinsk tolkning av skeletala skador från avrättningsplatsen Galgberget i Visby

This scientific essay contains an interpretation of injuries caused by weapons and traumas on the bones from the execution site Galgberget in Visby, Gotland. The site was used from about the 13th century to 1845 AD. The purpose is to examine the injuries and describe them, also to investigate what may have generated them. An important question is what bodily position the individuals had at the time of the injury. The methods presented in this essay can be associated with experimental osteology, also the basic methods such as sex- age- and stature- assessment has been applied where?s possible.

Passage Retrieval: en litteraturstudie av ett forskningsområde inom information retrieval

The aim of this thesis is to describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How well do the approaches work in experimental information retrieval (IR)? PR is a research topic in information retrieval, which instead of retrieving the fulltext of documents, that can lead to information overload for the user, tries to retrieve the most relevant passages in the documents. This technique was investigated studying a number of central articles in the research field. PR can be divided into three different types of approaches based on the segmentation of the documents.

Utveckling av metod för utvärdering av synnervens funktion hos häst :

VEP, visual evoked potential is an electrophysiologic test that can be used for evaluating the higher visual pathways. The aim of this study was to investigate if it is possible to adapt this method to horses. This method could have a clinical use in addition to the existing diagnostic methods that are available to evaluate vision in horses. Firstly, this study contains a summary of relevant studies done on animals and, secondly, an experimental part where the possibility of recording VEP in nonsedated and sedated horses is investigated and where to position the recording electrode to obtain the best results. Our results show that it is possible to record VEP in horses in a clinical setting. VEP was best recorded in the sedated horse to avoid movement artifacts and other disturbances.

Smal, smalare, smalast: en jämförande studie mellan Pro-ana och det "normala" smalhetsidealet

Syftet med studien är att undersöka Pro-anorexia (Pro-ana) bilders påverkan på kvinnor jämfört med vedertagna modellbilders påverkan. Blir kvinnor mer påverkade av att titta på extremt smala kvinnor än av att titta på "normala" smala modeller? En experimentell mellangruppsdesign, med 42 kvinnor från Lunds universitet användes. Den påverkan som mättes var matproblematik, tjockkänsla, idealkropp, självförtroende och affekter. Pro-anafilmer, modellfilmer och kontrollfilmer användes som stimulimaterial.

NO NAME - Fenomenet förståelse

This thesis examines the experience value of the wolf and wolf hunting presented in mediaduring December 17, 2009-Feruary 15, 2010. I analyze news articles, editorials and letters tothe editor in three newspapers. In order to investigate the experience value of the wolf and thewolf hunt, I have with inspiration from a model employed in the assessment of experiencevalue of tangible cultural heritage, developed a model which I use to analyze the mediamaterial according to the criteria of aesthetic value, identity value, value of tradition andsymbolic value. In order to analyze the results of the analyze, I employ experimental andsociocultural theory and method, which means that I assume the experiences of the wolf andthe wolf hunt as related to a social and cultural perspective that partly depends on how weidentify ourselves and what kind of experiences and understandings we have of the landscapeand large carnivores. Since media affects how we perceive our surroundings and the wolfhunting attracted much attention in media, I found it interesting to examine how the wolf andthe wolf hunt were displayed in news articles and letters to the editor.

Assessing the ability of LARGE overexpression to prevent the development of muscular dystrophy

Duchenne Muscular Dystrophy (DMD) is a hereditary X-linked fatal disease that affects 1 in 3500 male births. It is the most common kind of muscular dystrophy in children and leads to death in the late teens or early 20s for many patients. The mdx mouse is a model of DMD that can be used to investigate experimental therapies. Overexpression of a glycosyltransferase, CT GalNAc, in mdx mice has been demonstrated to prevent the development of muscular dystrophy. Overexpression of another glycosyltransferase, LARGE, is currently being investigated as a treatment for another group of muscular dystrophies, the dystroglycanopathies. In this study, we overexpressed LARGE in mdx mice in order to investigate its effect on the development of muscular dystrophy.

Den demokratiska lyxen

Abstract: The fashion industry is perhaps the most unpredictable one where change occurs very rapidly. In order to be attractive and interesting in this competitive industry, a brand must constantly be up to date and differentiated from other brands to attract the consumers. This has given rise to an increasing growth of brands that cooperate for marketing reasons and more specifically, clothing retailers that perform designer collaborations with exclusive designers to create limited collections.Studies describing the effects of those collaborations on the retailers brands are rare and especially from a consumer perspective. Since H&M has been a pioneer in designer collaborations and has done it more times and for more years than any other retailer we have conducted our study on their case. Our intention was to investigate how the designer collaborations have affected the brand equity and image of H&M, if the collaborations have increased the willingness to pay for H&M's other ranges and if they have affected H&M's ability to extend its brand to higher price segments, through an experimental study.

Jämförande studie av LEM2 och Dynamiska Redukter

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.

Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

Automatisk genreklassifikation : en experimentell studie

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

Karakterisering av bioslam för modellering av biogasproduktion

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Arbetsminneskapacitet: relation till verbalt flöde och indirekt minne för inhiberat material

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.

I jakten på en god natts sömn: Ett försök till manipulering av tankar innan insomning

I en single case experimental design (SCED) av crossover typ med fyra deltagare med insomni undersöktes möjligheten till att manipulera mängden negativa tankar innan insomning genom tillämpningen av två olika tankeexperiment, savoring och framkallad ruminering. Bland resultaten fanns signifikanta samband mellan mängd negativa tankar innan insomning och sömnkvalité, insomningslatens och antal uppvaknanden. Samband fanns även mellan mängd negativa tankar och obehag över tankarna. Dock visade det sig att experimenten inte påverkade mängden negativa tankar innan insomning då de sömnrelaterade faktorerna varierade oberoende av experiment. Variationen i de olika skattningarna på måtten gjorde att inga slutsatser kunde dras kring vad som orsakade sömnbesvären hos deltagarna eller vilken roll mängden negativa tankar hade för dessa.
