This report describes a Bachelor thesis work in which a robotised laser welding cell has been modelled and simulated for the purpose of making a presentation movie. The report shows that the work has been concentrated on making the movie from the modelling phase through the recording of the movie and ending up with the editing of the final presentation movie. A pre-study was made prior the Bachelor thesis work. In the pre-study a literature study was conducted about measurement and calibration of a welding cell. Measurement of almost all equipment in the entire cell was also conducted in the pre-study.

ProblemformuleringDet vi med denna uppsats vill undersöka är hur en tjänsteorganisations produktivitet kan mätas. Därför lyder vår problemformulering enligt följande: Hur kan produktivitet mätas i en tjänsteorganisation? Produktiviteten i en tjänsteorganisation påverkas av ett antal faktorer, till exempel personalen, kommunikation, ledarskap och de IT-system personalen arbetar i. Med ?mäta? syftar vi till att kvantifiera de kvalitativa faktorer som påverkar produktiviteten. SyfteUtöver att se hur produktiviteten kan mätas i en tjänsteorganisation ska vi utveckla en modell som visar hur tjänsteproduktiviteten kan mätas samt identifiera vilka faktorer som påverkar och hur de påverkar produktiviteten.

När företag ska implementera ERP-system är det viktigt att företaget ser till att få kvalitet på implementeringen. Ett ERP-system är ett informationssystem som ska hantera alla funktioner inom ett företag på ett integrerat sätt. För att få kvalitet på implementeringen krävs att budgeten hålls, att implementeringen blir klar i tid, att processerna i företaget optimeras, att kraven tillfredsställs och att integreringen med andra system klaras av på ett bra sätt.Examensarbetet har undersökt om Business Blueprints kan vara en hjälp för företag när det gäller att säkra kvaliteten på implementeringar av ERP-system. Business Blueprints är en modell som guidar företag genom hela systemutvecklingen. Undersökningen har genomförts med hjälp av intervjuer och en litteraturstudie.Resultatet av undersökningen som detta arbete omfattar kan sammanfattas med att Business Blueprints är en hjälp för företag när det gäller att kvalitetssäkra implementering av ERP-system..

The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

Organizational learning has become more and more important in the last decades as the environment in which organizations exist continues to change rapidly and unexpectedly. In order for organizational learning to happen, the individuals within the organization must learn. Just as different individuals possess different skills, each individual also has their own learning style. As the use of teamwork increases, so does the need for techniques to put high performing teams together and with organizational learning as one of the objectives the question is, how do we maximize learning, efficiency and performance in teams? This study uses a quantitative method to examine how teams, from a course at the Stockholm School of Economics, perform on the individual learning, team efficiency and team performance scale based on the individual learning styles within the team.

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

This paper presents a study that evaluates the performance of stock recommendations issued on Swedish stocks during 2003. The selection of recommendations in this paper originates from banks, major brokerage firms and financial press located in Sweden. The total of 171 recommendations consisted of 99 buy recommendations and 72 sell recommendations. Forecast revisions presented in this paper suggest that Investment managers have no ability to predict performance winners, nor do their forecasts in general have any significant impact on stock prices. A mere 50 percent of the recommendations in this revision had a weak ability to outperform their benchmark indexes as in other similar revisions.

Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.

The purpose of this paper was to investigate whether Suzanne Retzinger?s linguistic cues for shame and verbal behaviors for hiding shame could be used to measure shame in surveys based on Thomas Scheff?s theory of shame. I created a measurement instrument consisting of 30 statements, which were all meant to measure general shame.The instrument was administrated to 180 respondents studying at Karlstad University, of whom 4 respondents were removed from the data set due to lack of standardization. With the polytomous rasch model used for the analysis, data from 176 respondents were analyzed, of whom 124 respondents were female and 52 were male.The result showed that the measurement instrument?s statements should not be used together because the analysis indicated multidimensionality.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.
