Batterilyft för telekom basstationer

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.

Pojkars läslust : en studie av hur pojkar uppfattar och uttrycker sitt intresse för läsning

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.

För mycket information? : En analys av begreppet Information Overload mot bakgrund av det framväxande informationssamhället

This paper deals with the concept "Information Overload" (IO). It describes the intellectualcontent of the idea as well as its supposed domains of activity. Furthermore it problemizes theimage of "Information", "Information Society" and other concepts related to those phenomenons.A division by two fundamental different distinctions of IO are being made. InformationOverload serves as a name for:I. An information-intensive environment.II.

Att gestalta det inre : en Kierkegaardiansk analys av Vampyr och Ordet av Carl Theodor Dreyer.

The essay aims to show n interpretation of Vampyr and Ordet; seen from a viewpoint Kierkegaards christian existentialism can enhance the understanding of mentioned movies. Central notions from Ks philosophy are explained and then the author points to examples of how this corresponds with the essence of the two movies.The argumentation is based on Ks thoughts on faith and human existence. Other theories concerning Dreyers movies, and to some extent his background, is also discussed.Finally the author concludes that he was right in his hypothesis: that it is possible to show an influence from Kierkegaards christian, existentialistic thoughts in the two movies.Moreover the author thinks that the chosen perspective works as a complement to other written material on the movies and that other writers on the subject have some problems summing up the contents of the movies from their different perspectives.The final conclusion is thus that an interpretation of the movies from a Kierkegaardian viewpoint increases the understanding of the same movies.

Mjukvaruplattform för riggstyrning

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Pseudoslumptalsgenerering : En studie av pseudoslumpsalgoritmer i allmänhet med fokus på C++11-biblioteketRandom samt implementation av en modifierad XORShift

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..

Aktivitens betydelse för åldersrelaterad kognitiv försämring

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

Stress test methods : a potential approach to hurry up shelf-life tests on oat products

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

Perianestetisk omvårdnad av häst :

This work is a combination of a literature study and a practical pilotstudy. In the literature study essential physiological reasons of why anaesthesia of horses is so risky are explained. Diffrent methods of induction and recovery are brought up, together with significant aspects of positioning the horse on the operating table and perianaesthetic complications such as myopathy, neuropathy and limb fractures. The pilotstudy had the purpose of examine the bodytemperature of horses undergoing general anaesthesia and to control the perianaesthetic temperature measurements performed in Swedish horseclinics and veterinary hospitals. Our hypothesis was that the bodytemperature of the horses would decrease but not enough to cause a problem. The purpose of this work has been to gather more profound knowledges in the subject of perianaesthetic nursing of horses which is an important part of the assignment of a veterinary nurse..

Våga ta steget!: En studie om de attraktiva produktkategorierna

This paper studies patterns of consumption within a product category. Using make-up as a base for the study, we applied the Mokken Scale to examine if consumers follow a hierarchical pattern when buying items within the product category. Based on a survey of 250 female respondents, we establish a hierarchic scale for consumption. Assuming generally accepted attributes for determining physical attractiveness, the results of the Mokken Scale study were cross referenced with a survey among 200 male and female respondents. Students were asked to evaluate pictures of a model using different combinations of make-up, i.e.
