This project is about the development of a application to aid deafblind people with time understanding. The application is written in C# language and have multiple functions to alarm the user. The application can alarm deafblind persons through a combination of sounds, pictures and vibrations. This makes the application very flexible and can be used by many different groups like deaf, blind and older people. This application have been evaluated by staff from Mo Gård resurscenter..

We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Title:Chillchain for cut flowers ? how the distribution works.Author:Anna-Maja Svarén, student at Lund Institute of Technology, mechanical engineering.Supervisors:Annika Olsson, Department of Design Sciences.Bengt Sahlberg, Bioett AB.Problem:How does the distribution of cut flower works regarding temperature, losses, responsibility, complaints, packaging and weak points?Purpose:The purpose is to map the distribution of cut flowers, with focus on losses in the temperature, from farm to store. The goal is to identify weak points in the chillchain and to se how wrong temperatures affect the flowers. The results can be a help to secure the chillchain.Method:The work started with a problem; map the distribution of cut flowers with focus on temperature losses. Data was collected on the basis of this problem, then analysed, and finally conclusions were drawn.Conclusions:The affect handling and distribution has on a cut flower is very complex.

Användartillfredsställelse har visat sig vara ett viktigt mått på informationssystems framgång. Mycket forskning om användartillfredsställelse med traditionella informationssystem har utförts. Data Warehouse är dock ett nytt fenomen som på flera sätt skiljer sig från traditionella informationssystem. Denna uppsats syftar till att utforska vilka faktorer som är viktiga för användartillfredsställelse med Data Warehouse samt att diskutera kring dessa faktorers betydelse. För att kunna göra detta har en flerfallsstudie med fem användare utförts.

Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

Idag har vi mängder av data på våra lagringsmedia vilket gör dem till en värdefull informationskälla. Om denna data raderas betyder det inte att den är borta för alltid. Data finns fortfarande kvar på lagringsmediet och går att återskapa med så kallad file carving. Att kunna återskapa data är en viktig del inom den polisiära verksamheten, men även för andra verksamheter som förlorat data. Det finns dock vissa problem som kan ställa till med besvär när data ska återskapas. När filer inte är lagrade i sammanhängande datablock blir de fragmenterade vilket innebär problem.

The purpose of this essay is to examine if the judgments of accountants differ, in different cases, between the old and the new law. The method we used to investigate the differences was a combination of experimental and non experimental. Our analysis is based on a survey investigation with ten cases. These cases are produced from a model in which the accountant tests his independence. The survey was sent by mail to about a hundred accountants.

Detta arbete har som utgångspunkt att specificera, implementera och utvärdera ett verktyg som har som syfte att ta fram resultat från frågeställningar mot registrerade data från flygplanssimulator. Detta görs genom framtagning av kravspecifikation och en iterativ programutvecklingsmetod. Ett utvärderingstest i simulator utfördes för att samla data som sedan analyserades med verktyget. Detta för att undersöka om det går att hitta tillfällen där hög kognitiv belastning upplevdes..

Behovet av datautbyte mellan olika system, ökar ständigt. Därför byggs fler och fler system med möjligheten att utbyta och överföra data via XML. Då olika system lagrar data på olika sätt, måste de strukturella och innehållsmässiga skillnaderna hanteras innan data kan överföras.Syftet med detta arbete är att undersöka hur dataöverföringar mellan XML-dokument i flera steg påverkas av strukturella eller innehållsmässiga skillnader. Arbetet visar i vilka fall data inte kan överföras korrekt. Studien utförs genom en experimentell metod.

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.
