Jämförelse av olika reglersystem för undervisningsändamål
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..
Budgetstyrning och Balanserat styrkort : i form av en kombinationsmodell
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.
?Folkbibliotekets funktioner i det lokala samhället? ? En idéanalytisk studie av fyra biblioteksplaner
The aim of this master thesis is to investigate the ideas about functions that public libraries have in the local society. We have used the method idea analysis on four municipal library plans, to find out which ideas about library functions that frequented each plan, and what similarities and differences there were between the ideas about functions in each plan. As a theoretic base, we have used a theory about three dynamic spheres in modern society: the state market and civil society, and examined how these three spheres influence and control the library functions. We have extracted six different ideas about library functions: educational, social, economical, entertaining, serving and democratic functions. The most dominating ideas in this study are ideas that the public library should be an educating and formative institution.

?terfall i brott som ett problem p? politisk och institutionell niv?. : En kvalitativ unders?kning av sambandet mellan straff och rehabilitering inom svensk kriminalv?rd.
This study looks at how probation, client experiences, and criminal policy decisions affect recidivism in Sweden. Gaining a thorough grasp of how social, organizational, and political issues interact and impact the chances of rehabilitation and reintegration is the goal. Three research questions are addressed in the study: First, what are the causes of recidivism? Second, how is probation perceived by staff and clients in terms of control and support? Thirdly, what effects do political decisions have on probation services' operations and clients' chances for recovery?? A qualitative study was conducted with semi-structured interviews with twelve respondents, eight probation clients, three probation officers and one parliamentary politician. There were six themes that discussed the issue of recidivism from different perspectives, the collected data was analyzed through thematic content analysis.
Fotröta hos får : en kartläggning av hur olika länder hanterar sjukdomen
Foot rot is a severe claw disease which occurs among sheep and goats in most parts of the world, with outbreaks in hot and humid weather. It is a contagious bacterial infection caused by Dichelobacter nodosus in association with Fusobacterium necrophorum. Foot rot has a negative impact on both animal welfare and economy.This thesis presents how Australia, Nepal, Norway, Switzerland, Great Britain, Sweden and Uruguay handle foot rot. In the selection of countries the focus was on countries that have control- or eradication programs against foot rot. There are differences in the climate, animal husbandry practices, animal welfare and economic resources in the countries that are presented.
Modebloggarnas dolda budskap?
The accounting scandals that have attracted attention in recent years have led to internal control becoming a more central part of business activity. Doubts about what firms actually do have increased, all caused by the attention of accounting scandals. To counter this, frameworks and laws evolved and gained a significant role in the organization and its surroundings. The aim of the present study is to find out how four companies in the Kristianstad region are working to ensure its internal control and how they work to minimize risk and reduce uncertainty. We have used a qualitative method and interviewed a person in a senior position in each company.
Mätningar av statiska och dynamiska egenskaper för bakaxel.
To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.
Idiopatisk epilepsi : en fallstudie
Epilepsy is a common neurological condition in dogs, being a common reason for
death in the statistics from the insurance company Agria in Sweden. Among the
different types of epilepsy, idiopathic epilepsy (IE) is the most common and is
characterized by the fact that a veterinary examination does not reveal a cause for
the seizures. This study has been conducted through studies of medical records
and interviews with dog owners. From a total number of 103 dogs that were
neurologically examined for seizures, 42 dogs met the inclusion criteria, being
classified as having idiopathic epilepsy. When the study was performed, 28 dogs
had died, while 14 were still alive.

Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.
Developing Dynamic Outsourcing - Bringing continuous added value to the ABB Full Service partnership
Executive summary This master thesis was originally based on a specific assignment given to the authors from ABB Full Service, a unit specializing in providing maintenance outsourcing: ?How can ABB Full Service expand its offering of providing fundamental maintenance by seamlessly incorporating the business concept with competencies and solutions from other ABB divisions?? The academic issue was developed throughout the thesis, resulting in the following formulation: ?From an organizational perspective; how can service providers bring continuous added value to intra-organizational outsourcing partnerships?? Many of the key findings of this thesis are reflected in the issue. The term intra-organizational outsourcing is a proposed addition to the terminology in the academic discourse on outsourcing. The definition of the term is: ? Where an organization outsources a business process interlinked with the physical operations, requiring the service provider to take over a preexisting unit and its employees.This is an accurate description of the form of outsourcing that ABB Full Service is engaged in.
Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.
Modern kontra traditionell styrning : - en studie av traditionellt tillverkande företag
Bakgrund: Traditionell styrning har kritiserats av en rad olika författare och en modern verksamhetsstyrning har utvecklats. Vi menar att traditionella tillverkande företag är intressanta ur den aspekten att traditionella ekonomistyrningsmodeller är uppbyggda kring dessa typer av företag. Frågan vi ställer oss är alltså huruvida modern verksamhetsstyrning är ändamålsenlig i traditionella tillverkande företag.Syfte och metod: Syftet med den här uppsatsen är, att beskriva och analysera tillämpningen av traditionella och modernare verksamhetsstyrningsmetoder i traditionella, tillverkande företag. Vår empiri är baserad på sex olika kvalitativa intervjuer på företagen Cloetta Fazer, Milko och Skånemejerier.Resultat: Traditionellt tillverkande företag möter inte samma förutsättningar som tidigare och behöver därför på många plan anpassa sin styrning..
