Flervariabel reglering av industrirobot

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

SYNS VI I SVERIGE? : En rättssäkerhetsstudie om barn i migrationsprocessen

The current thesis is on the rule of law and how the principles of the rule of law are met in thenew Swedish migration process. The migration process has been subjected to criticism duringseveral years and on different occasions. The migrations process is viewed through a ?rightsof the child? perspective, foremost to seek if the rights of the child are met. The children are avulnerable group, not the least in the process of migration.

ADS och Matlab för optimering av pre-distortion av effektförstärkare

This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.

Vanebeteende - Det lojala beteendet?

The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.

Indentifiering och reglering av industrirobot med hjälp av accelerometer

Dagens robotindustri har som mål att bygga billigare och lättare robotar, vilket ger allt vekare robotar. Denna rapport studerar identifiering och reglering med en extra armsensor ? accelerometer ? på en flexibel industrirobot. Studien har skett både simulerat och experimentellt på en industrirobot.Vid identifiering med accelerometer befinner sig accelerometern i ett roterande koordinatsystem. Denna rapport presenterar en kompenseringsalgoritm för att transformera signalerna från det roterande koordinatsystemet till ett rumsfast koordinatsystem.I denna rapport presenteras regulatorstrukturerna I-PID, II^2-PID och LQG, vilka alla återkopplar motorvinkel och armvinkelacceleration.

Unga musikkonsumenter : En studie av vad som påverkar unga konsumenters val av populärmusik

Den uppsats som i följande beskrivs har syftat till att ur ett konsumentperspektiv undersöka och förstå vad som gör att unga konsumenter väljer att lyssna på den populärmusik de lyssnar på. Detta för att förstå hur marknadsförare ska marknadsföra artister i den förändrade musikindustrin. För att uppnå detta syfte har tre stycken fokusgrupper genomförts med ungdomar i åldrarna 16-18 år från Stockholm. De frågor vi formulerat till fokusgrupperna baserades på hur unga konsumerar musik, hur de skaffar information om musik, vilken roll spelar andra ungdomars musikval, vad som skulle få dem att betala för musik, hur de definierar sin personlighet, samt hur de visar grupptillhörighet. Svaren tolkades utifrån teorier inom konsumentbeteende och marknadskommunikation.

Perioperativ trycksårsprevention - en litteraturstudie om operationssjuksköterskans skyddande åtgärder

ABSTRACTPressure ulcers are a serious health damage that causes great suffering, prolonged hospital stays and increased health care costs. Patients undergoing surgery are at high risk of developing pressure ulcers and it is the operating theatre nurse responsibility to protect against health damage through nursing. There are little research made in the area of perioperative pressure ulcer prevention. In order to investigate perioperative pressure ulcer preventive care measures that are described in the litterature and to answer the question how the operating theater nurse can protect the patient, a pilot study of a systematic literature review was carried out. Data base searches were conducted in PubMed and Cinahl from where ten articles were selected and examined for their quality and content.

Smakprov av Sverige : En undersökning av två brasilianska musikstudenters upplevelser och tankar kring lärandet av och mötet med svensk folkmusik.

Under 2014 sökte fler än 74 000 människor asyl i Sverige för att komma undan bland annat krig och förföljelse. Det är Migrationsverkets uppdrag att ge människorna bostäder under asyltiden. Men antalet asylsökande har under de senaste åren ökat och när fler kommer räcker inte myndighetens boenden till. De får då hyra tillfälliga asylboenden av privata aktörer.Syftet med detta examensarbete har varit att undersöka hur öppnandet av ett privat asylboende har påverkat en mindre ort i Sverige och de människor som bor och verkar där. Ambitionen har varit att bidra till medierapporteringen med en bredare och nyanserad bild.

Cystisk endometriehyperplasi/pyometra-komplexet hos hund : orsaker och patogenes

Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

Implementering av realtidsvideolänk med MPEG- och wavelet-teknik

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

Förebyggande arbete mot våld och hot om våld inom socialtjänsten : En kartläggning av chefers upplevelser

Dealing with threats and violence at the workplace is a reality for many social workers, where a majority of them have to face client oriented incidents at least once during their career. Incidents are most commonly expressed as threats and harassments, but can also take place in the form of physical violence. Looking at the problem from a supervisor perspective, it will affect and possibly damage the specific exposed employee, the workplace as a whole and the clients. Supervisors are the ones responsible for developing workplace enviroments that are satisfyingly safe, for which guidelines can be found in law as well as in an emerging research area. Reasons as to why some people tend to become violent is as complex as reasons as to why some people seem to be more vulnerable or exposed than others. That is why means of preventing threats and violence can not be explained in one single way, but the answer must be sought on several levels.

Launch of new products : market research for new product development for diabetics

Foods that stimulate health and satisfy consumer expectations are needed. In a consumer´s perspective, products that provide several kinds of health benefits, without any call for major changes in their behaviour are needed on the market. With this increasing interest in health promoting food product, one of the biggest challenges for the food industry is to find the conditions and right position on the market and find the opportunities to enter the market successfully. New products with added health values can be developed to cure and counter welfare diseases as in this case for diabetics type 2. Swedish food companies have a desire to respond to welfare diseases and one welfare disease is diabetes type 2. Many of them have an ambition to develop new products to respond to the growing population and find a supply that could suit their customers.

Dynamisk simulering med hjälp av RPS-beräkningar för radiovågors utbredning i urban miljö

Militära insatser i urban miljö kommer troligen att öka alltmer. Detta kräver soldater till fots eftersom dessa lättare kan förflytta sig via och mellan byggnader. Varje deltagande soldat kommer att behöva egen radioutrustning. Då stadsmiljö är ett relativt outforskat område vad gäller militär radiokommunikation är det viktigt att öka förståelsen för radiovågors utbredning i stadsmiljö. Härtill har institutionen för Informationsöverföring på FOI köpt in programmet Radiowave Propagation Simulator (RPS).

Att utvärdera vetenskapliga tidskrifter: En kritisk analys av Journal Impact Factor: en metod inom citeringsanalys.

The purpose of this Masters thesis is to make a critical analysis of Journal Impact Factor JIF. JIF is today the most widespread quantitative measure for evaluating scientific journals. Although it is internationally used and is considered authoritarian many problems have been observed. This has led to that the validity of JIF has been questioned. To identify JIFs limitations the following issues have been raised: Which are the problems with citation analysis? What criticisms have been directed towards Journal Impact Factor as a measure for evaluating scientific journals? The theoretical framework consists of theories about citation behaviour and a discussion about the characteristics of a scientific journal.
