The society has always tried to get rid of those who do not "fit in". They doesn't follow the normal behaviour and rules and have to be "dismissed". The community has developed different kinds of institutional care for individuals with dysfunctional behaviour. Those institutions are mental hospitals and prisons. Many of these institutions put the individuals in an extreme situation since they loses their independence and freedom.

Utvecklingen och användningen av ERP-system har blivit allt vanligare och trots att ett sådant system kan bidra med effektivitet kan implementeringen av ett sådant system innebära en omfattande organisatorisk förändring. Vid en förändring i form av införande av ny teknologi inverkar befintliga rutiner och institutioner på huruvida stabilitet kan upprätthållas. Stabilitet kan upprätthållas då nya regler går i linje med rådande rutiner eller vid närvaro av en lös koppling mellan dessa. Uppsatsens syfte är att genom en fallstudie undersöka om och isåfall hur stabilitet och förändring kan samverka vid implementering av ett ERP-system. Studien visar att detta är möjligt, dels tack vare att de anställda får vara delaktiga, att de inser förändringens huvudsakliga syfte samt att de nya reglerna går i linje med rådande rutiner och institutioner.

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Denna studie har som syfte att underso?ka om det finns en typ av system vars egenskaper liknar ba?de traditionella system och e-infrastrukturer utan att tillho?ra na?gon av dessa typer samt hur en designmodell skulle se ut fo?r denna typ av system. Detta system kallar vi gra?nsfallssystem.Fo?r att underso?ka om denna finns har traditionella system och e-infrastrukturer samt hur man utvecklar dessa typer av system analyserats. Detta fo?r att se ifall det existerar na?gon form av system som har egenskaper fra?n ba?da dessa ytterligheter och om det existerar sa?dana system hur man pa? ba?sta sa?tt ska utveckla dem.

The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

An important task for project managers in multi-project environments is to effectively choose the right people to the project team. For organizations, it means being able to prioritize and plan human resources among the various projects running in parallel. The purpose of this paper is to describe how a project manager in multi-project environments looks at the allocation of people in their projects. We did our research through literature reviews and interviews with seven project managers.The research shows that the studied organizations highlight both the expertise and the personal factors in an election. They do not use any specific personality test to identify their staff.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

The harness racing industry has roots hundreds of years back in time and breeders through time have changed the horses to a mix of potential, harmony and speed. Breeding has changed the conditions and created a horse that perform better and better. A risk with high-performance horses is that injuries related to training and racing may occur more often. In training and racing situations, lameness is the most common injury. There are many factors affecting the occurrence of injuries and lameness of the trotter horses, such as how the horse is trained and raced, the surface condition of the racetrack, banking and angle of the curves of the racetrack and how fast injuries are discovered and treated.
