Hur organiserar forskare sitt material? : Personlig informationshantering i en vetenskaplig forskningsmiljö
The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.
Erosionsskydd i strandzoner :
Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.
PRAKTISK BESTÄMNING AV KLÄMKRAFT OCH FRIKTION I SKRUVFÖRBAND
This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.
Gårdssmedjor i södra Gästrikland En studie av Hedesunda och Österfärnebo socknar
Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.

Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
Den djupa muskelfunktionen hos kvinnliga elitvolleybollspelare : En studie om transversus abdominis funktion påverkas av stabilitetsträning.
Background and purpose: Volleyball requires a lot of the human body, andeffective core stability is necessary for the athlete. Our muscles cooperate as achain of motions and core stabilization is the base for the moving muscles.The most well-known stabilization muscle is m.transversus abdominis (TrA).The purpose of the present study was to evaluate the function of TrA inSwedish female elite volleyball players and to observe the influence of eightweeks of stabilization exercise on the TrA. Method: 10 female elitevolleyball players (mean age 24,7 years, range 18-31 years) participated inthe study. TrA was measured in supine position with a pressure biofeedbackunit. Subjects were instructed to draw in the abdominal wall without movingthe pelvis and hold for 10 seconds.
Olika områden olika förutsättningar : En jämförande studie av föreningslivet mellan Danderyds kommun och stadsdelen Spånga-Tensta
This study aims to investigate associations in two areas in Stockholm County with diverse socio-economic conditions. The study intends to examine the impact these differences have on what role the bureaucrats and politicians in the two areas think that the associations should have. Bureaucrats are those who design guidelines for associations and that is why they have an important role in the conditions of the associations. A comparison between the two areas has been made to see if the requirement in the guidelines for the areas are different according to where the members live. The two areas that have been used to compare the guidelines of associations are Danderyd municipal and the district Spånga-Tensta.
Kundlojalitet : en studie om vilken påverkan de demografiska aspekterna har på kundens lojalitet mot sin bank.
In Sweden today almost all people are connected to a bank in some way. It can range from loans, savings, shares, etc. They have a current account where salaries, student aid etc. is paid. Due to the large selection of banks, it has become more important for banks to be competitive in their services to their customers so they don?t change bank.
Förgivettagen heterosexualitet : En analys av fyra skönlitterära böcker i relation till skolans värdegrund
This thesis is based on qualitative text analyses of four works of fiction, used as teaching materials in the school subject of Swedish, from a queer theoretic perspective. The purpose of the study is to examine how sexual identities and expressions are being presented, as well as what positions are offered a reader, in relation to the heterosexual norm. Basis for this thesis are the schools fundamental values, which highlights the importance that intolerance be confronted through both knowledge and active measures, and the syllabus, which states that fiction should be viewed as a tool for identity development as well as an understanding of the outside world.The analyses reveals a distinct connection between the generally accepted heterosexual norm and a professed (or taken for granted) heterosexuality which is being carried out by the characters or the books as a whole. Out of the four titles only one disputes this norm, by offering a wide range of sexual identities and expressions. These expressions, however, are being invalidated ? through insufficient ability to relate to the norm ? or made invisible ? through an imagined heterosexuality which, by superiority over other expressions, excludes them..
Herbs for horses
The aim of this study was to find out how many and which of the herbs used for horses that have been scientifically studied with results to justify the use. In order to find out which herbs that are commonly used by horse-owners a phone interview was performed where six companies selling herbs for horses was contacted and asked to provide information on the most sold herbs for horses in Sweden. Devil's claw (Harpagophytum procumbens), chamomile (Matricaria recutita), dandelion (Taraxacum officinalis), nettle (Urtica dioica) and monk's pepper (Vitex agnus-castus) where the most sold herbs, followed by marshmallow (Althaea officinalis), burdock (Arctium lappa), marigold (Calendula officinalis), purple coneflower (Echinacea angustifolia/purpurea), cleavers (Galium aparine), licorice (Glycyrrhiza glabra), rose hip (Rosa canina), thyme (Thymus vulgaris) and vervain (Verbena officinalis), in no particular order. Of the most used herbs, research with focus on the use for horses was found for purple coneflower, licorice, devil's claw, monk's pepper, rose hip, thyme, and vervain. These studies did not cover the whole range of traditional use for the mentioned herbs, and more studies are needed to be able to claim that these herbs have, or have not, scientific support for use in equine management..

Upplevelser av skam och avvisande hos deprimerade unga vuxna
Depression in young adults is a serious condition causing serious suffering for the victim. By finding risk factors for depression the opportunity for early preventive action is increased, which, in turn, may prevent a negative course. Two risk factors which have been shown to be related to depression are shame and rejection. Therefore this study examined the relationship between shameproneness, rejection sensitivity, shame-related events and depressive symptoms. The self-report questionnaires used were TOSCA, RSQ, Shaming index and BDI-II.
Idéer om samhälle och individ : Abortdebatten under 1960- och 1970-tal med inriktning på realpolitik och ideologi
Julia Rolandsdotter, Idéer om samhälle och individ: Abortdebatten under 1960- och 1970-tal med inriktning på realpolitik och ideologi, Uppsala Universitet: Institutionen för idé- och lärdomshistoria, C-uppsats, HT 2013.This essay aims to investigate and scrutinize the debate surrounding abortion during the years of 1964 and 1974 respectively. By analyzing elements of different opinions in the debate from daily press, a wide range of aspects concerning the issues of free abortion have been distinguishable. This analysis shows that the abortion debate was, to a high degree, a question of Realpolitik and ideology whereas the differences over time have been visible rather than the differences between parties of varying opinion. By applying the theories of Ian Hacking concerning the effects of categorization, ideas surrounding people and society among others, have been highlighted in the debate. In 1964 we see ideas about the woman as motherly or a victim and the society as defective or exposed among other factors.
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.
