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.
Museum på webben - en undersökning om användbarhet och åtkomst
The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.
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.
Projekt Arbetsstuga utbildnings CD
Projektnamnet - ?Arbetsstuga Utbildnings CD? beskriver ganska bra vad vi gjort, nämligen att vi tagit fram en prototyp för en Utbildnings CD för GIS användare. Arbetsstugan som är en grupp ideellt arbetande människor var uppdragsgivare och ville att deras tidigare projekt, Projekt Arbetsstuga, nu skulle lanseras på en CD. Ett par tidigare CD-skivor hade skapats men dessa innehöll en del felaktigheter. Nu skulle den en gång för alla rättas till, så att den skulle kunna släppas vidare för distribution.

En socialpsykologisk studie om organisationsvisionens betydelse för sociala relationer i arbetsvardagen
In this study, we have considered the impact the organization`s implementation of its vision of the psychosocial work enviroment has been for the relations between the employees. We have primarily relied on a hermeneutic approach to understand our empirical data, and when we have interpreted and made a socialpsycological analysis on our collected empirical data. We have used Smith´s Institutional Ethnography, Sheff`s Social bonds and Asplund`s theory of Social responsivity. To collect the empirical data we have combined quantitative and qualtitative methods and a textanalysis at a visiondocument in the aim of capture both the depht and the breadth of our chosen fields of study. The results we have found shows that the psycosocial work environment within the organization can be seen as interplay between individual and enviroment and between individuals as well and that this interaction is influenced by the organizational culture that is created by the organization`s political vision.
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.

Finns det en trend i psykisk ohälsa hos högstadieelever? : ? Skillnader i familjesituation, nationellt ursprung och kön
Syftet med denna studie är att med longitidunella data, där man följer samma individer över tid, från 2000-talet ta reda på om det finns en trend i psykisk ohälsa hos högstadieelever. De rapporter som finns baseras på longitudinella data som inhämtats före 2000-talet och därför avser denna studie att delge fältet ny och aktuell kunskap då denna studie baseras på longitudinella data från 2004 och framåt. Vidare ämnar studien undersöka huruvida tonåringarnas familjesituation och nationellt ursprung påverkar en eventuell trend i den psykiska ohälsan samt om det föreligger någon skillnad mellan pojkar och flickor. Resultatet visar att det finns en signifikant skillnad i psykisk ohälsa över tid och att flickor i större utsträckning än pojkar upplever psykisk ohälsa. Ingen av de övriga variablerna visade på någon signifikant skillnad, varken nationellt ursprung (p =.631), familjekonstellation (p =.300) eller pilotskola (p =.138).

Informations- och kommunikationsteknologiers betydelse i utvecklingsarbete : En intervjubaserad studie om IKT:s betydelse för indiska kvinnor
New forms of Information and Communication Technologies (ICTs) have become more influential in development contexts. The concept of ?The Digital Divide? points at a large division between rich and poor countries regarding access to ICTs. Critics say that the debate concerning this topic for far too long has focused mainly on the technology itself rather than social factors which impact social inclusion and development. Scholars agree that ICTs holds a tremendous potential, but how is this implemented in development contexts and how can it be used with more sensitivity towards local preconditions and social aspects?This paper aims to examine how ICTs are being used in the context of development within an India based organisation for women called SEWA (Self Employed Women?s Association).
