This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.

The purpose of this essay has been to examine whether attitudes and behavior among Swedish people who takes snuff are dissonant or not and how their attitudes are affected by the media debate about the health risks snuff can cause. Furthermore, we were interested in finding out how different reference groups´ attitudes would influence the attitudes and the willingness of people to stop taking snuff and investigate how much control the people who take snuff think they have. To answer these questions we chose to ask primarily students at Stockholm University and Södertörns Högskola. The students were asked to fill out a questionnaire with 22 questions and the 100 responses we collected were worked up in a statistic program, SPSS, on the computer. The main models used for the essay and for the questionnaire were the Theory of Planned behavior and the Dissonance theory.

PurposeThe purpose of this study has been to investigate the documentation process following the guiding principles of the Quality Norms for Fall Prevention concerning fall risk assessment, risk identification, fall preventive measures, information and the making of an individual care plan.MethodThis study is a quantitative, descriptive and retrospective journal review study. There were 100 journals examine the existing documentation concerning fall risk assessment of patients who received treatment in geriatric patient care. The sample was consecutively.ResultsThe results showed that fall risk assessment was documented in 79 of 100 examined journals. 56 (71 %) of the fall risk assessments were made within 24 hours. In 59 of 100 journals the patient, relatives or former caretakers was asked whether the patient had had a fall within the last year, and in 61 of 100 journals it was documented that the nursing staff had made an assessment that the patient was going to have a fall during his or her length of stay if no preventive measures were set in.The majority of fall risk factors and fall preventive measures were documented within the areas of walking and transfer. It was documented that the patient was informed of fall risk, fall risk factors and fall preventive measures in 15 of 100 journals.

The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

An explorative study on the work motivation of employees at a retirement home. The three main factors are internal motivation, external motivation and control. A comparison between how important they estimate the different factors to be and how they experience them today reveals which factor is their key motivator and which areas that need improvement. Results indicat that internal and external motivation are slightly more important than control. And the amount of perceived control reflects the amount of creative and initiative behaviour of the individual.

AbstractBackgroundParkinson?s disease is a chronically not curable progressive disease that leads to different degrees of disability. Controlled studies on how patient education influences subjective health in Parkinson?s disease are lacking.AimThe aim of this study was to examine the influence patient education had on drug requirements and on subjective health status of persons with Parkinson?s disease.MethodologyA short form of Health Survey, SF-12, was used to measure perceived health. SF-12 was administered before and one month after patient education (intervention group; n= 48), and in waiting list control (n= 48).

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

Arbetsplatsmobbning har omfattande konsekvenser för individer i arbetslivet och samhället. Observatören har en viktig roll i arbetet mot mobbning, då dennes ingripande kan influera andra att göra detsamma. Denna studie undersökte om observatörens kön, locus of control och erfarenhet av observerad mobbning har en påverkan på intentionen att ingripa vid en mobbningssituation. Detta prövades utifrån sex hypoteser och frågeställningen hur relationen ser ut mellan ovangivna variabler i förhållandet till intentionen att ingripa vid mobbning. 165 individer i arbetslivet, varav 114 kvinnor, besvarade en enkät vilken innehöll Rotters The internal-external scale, en justerad Negative Acts Questionnaire-Revised och ett instrument inspirerat av Hektner och Swensons påstående om intentionen att ingripa.

Swedish clubfootball of today involves more money than ever before. This developmentdepends on the higher interest for football in Sweden which generates more revenues fromaudience and TV-contracts, which leads to more money from sponsors and an increasingmarket for selling souvenirs. Despite the fact that the increasing interest has generated morerevenues, we can still see reports in the media about economic problems in some clubs. Whatis the reason for this? Do the clubs have the ability and knowledge about economic controlthat it takes to run such a business as the clubfootball in Sweden has become?Purpose: The purpose of this study is to examine the economic control in a number of clubsplaying in the two Premier Divisons of the Swedish Football League.

Examensarbetet syftar till att jämföra nya alternativ till olika system för användning i laborationer i reglerteknikkurser för olika studentkategorier. Det skall utredas vilket av ett antal alternativ till mjukvaruplattformar som är bäst lämpat att användas vid reglerteknikundervisningen i ITN:s reglerlaboratorium vid Linköpings universitet. Tidigare laborationer i berörda kurser skall även modifieras så att dessa kan genomföras i de nya systemen.Examensarbetet resulterade i en rad modifierade laborationer och system att tillämpa i dessa. De nya systemen medför att all reglering sköts direkt från en dator istället för tidigare variant med externa apparater som programmeras. På så sätt kan större fokus läggas på regleringen i sig och inte de system som tillämpas för att utföra den..

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.
