Jämförande tidsstudie vid riskörning med kompakteringsskotare och traditionell ?lätt? modifierad skotare :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder. Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.

Analys och utveckling av inbyggda GPS-applikationer f¨or anv¨andning inom fordonsindustrin

This thesis is a part of the DySCAS (Dynamically Self-Configuring Automotive System)project which has the overall purpose of creating a middleware for the electronics in an automotive environment. The thesis has been made with collaboration with ENEA AB who is a member of the DySCAS project. ENEA AB has developed a demonstration platform to test the fundamental ideas which the DySCAS project is built on.The purpose of this thesis was to design and implement a GPS application to be added to the demonstration platform. This was done by adding a GPS receiver to the original DySCAS demonstration platform and designing and implementing an application to be able to extract the information from it. The resulting application is able to present cur- rent position and absolute time to the DySCAS networks as services to be used by other applications or by the network it self.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Är det mänskligt att fela? Synen på misstag och disciplinpåföljder i militär flygverksamhet och i hälso- och sjukvårdens verksamhet.

In the essay, the view of mistakes and disciplinary sanctions within the military aviation and health and medical service, are compared. The comparison shows that military aviation and health and medical service could have several points in common on how mistakes may occur, but that the present view of mistakes is different betwen the sectors. The view of mistakes and disciplinary sanctions is explicit within military aviation, and is based on a clear ideology on how mistakes occur, which is characterised of a systematic approach. Within health and medical service, an explicit and unequivocal ideology on how mistakes occur is missing, but, however, there are implicit ideas about infallibility and perfection. The comparison indicates that the view of mistakes is also, possibly directed by a bureaucratic model (instead of an ideology on mistakes), which aims to legitimacy, but that this may happen on the expense of not taking surrounding circumstances into consideration.

Tryckpulsgenerering för funktionskalibrering av mätsystem

The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.

Att samtala om sexualitet -- VÅRDPERSONALS ERFARENHETER AV ATT SAMTALA OM SEXUALITET MED PATIENTER VID EN KARDIOLOGIENHET

Talking about sexuality -Medical staffs´ experiences of conversations about sexuality with patients at a cardiology unit The background of this essay is the taboo to talk about sexuality among people who suffer from some kind of illness. When a person gets ill and need medical attention, his or her life changes dramatically. The patients get treatment for their symptoms. The illness and treatment have often an influence on the patient?s sexuality.

Implementation av ett interface till Emotiv Epoc

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Att utveckla medicintekniska informationssystem på rätt sätt : En studie om regulatoriska aspekters påverkan på systemutveckling och IT-innovation inom hälso- och sjukvård

IT is often seen as a solution to many problems concerning effectiveness in organizations. Information systems within the healthcare sector is often viewed as medical devices rather than just systems or services. These medical devices are thoroughly regulated by laws, standards and certifications. In this study I participated in an innovative project that aimed to bring new life and use to the old fashioned patient journal by giving it a visual representation through the use of an avatar. I aimed to study the effects of regulators connected with the patient journal as a source of information for the innovative project.

Patientinformation, vilken profession förmedlar den bäst? En systematisk litteraturstudie med tillhörande begreppsanalys.

This thesis is a systematic review of the Swedish healthcare and hospital-library?s authorities on the consumer health information. The goal is to evaluate the strengths and weaknesses that are inherited in two professions (medical and LiS) with two completely different perspectives on mediating information.The method used is a mix between conceptual analysis of the Swedish term ?patient information? and a Critical conceptual analysis, according to Fairclough, of published native theses and international professional journals.Conclusion of the thesis is that although the nursing and medical staff has the necessary medical expertise it does not, in many cases have either the time or skill to completely satisfy a patient or his/her next of kin´s information needs when exposed in a uneasy situation as when in need of treatment or help in any kind.The hospital librarian on the other hand does have the intermediating skills and most often the time to explain complex treatments or medical procedures, but the lack in medical or nursing expertise.In a perfect setting there is an inter-professional cooperation which brings a lot of positive results. The problem today is often to overcome the gap in awareness of one and other that exists in a modern Swedish hospital..

Att plocka russinen från kakorna : En studie om hur kuratorn inom hälso- och sjukvården arbetar med och utvecklar sin kunskap inom krisstöd.

This thesis aims to explore how medical social workers/counselors perform their workwith people during crisis and how they accumulate and practice scientific crisisknowledge. This study is an empirical research paper based on qualitative interviewsconducted with eight medical social workers. The data was analysed with Kvalesmodel for categorization, which constitutes the basis of the research. The results ofthe research was then analysed with the use of Cullbergs crisis theory and a model ofevidence based practice which is described by Topor and Denhov. The results showthat the medical social workers practice the evidence based practice model, describedby Topor and Denhov, in combination with Cullbergs crisis theory.

Research and development for expanding usability of a
multi-touch device

As new ways of using computers are constantly being developed, other ways of interacting are made possible. One of the most desired types of interaction with computers is a touch-screen where the user can actually organize everything simply by using the fingertips. The purpose of this project is to enhance an existing framework with an application that works with a touch-screen device. The application is to be used as a tool for presentational usage. The result is an application where the user by simple means can use a touch-screen to hold a professional presentation.

Översvämningsanalys med hänsyn till Länsstyrelsens handbok : Planering för stigande vatten i Kristinehamns kommun

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.

Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
