In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

The aim of this essay is to examine how the Internet functions as a communication channel to Event Marketing. We have investigated what makes the Internet unique as a communication channel for events and how Internet has been used for event marketing. We have mapped fundamental theories within marketing, media, communications and human-computer interaction, which together describe event marketing. We have carried out case studies on two event-marketing projects where the Internet has played a major role. The first project was XCT which is a project developed by the company Eventum AB.

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

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.

The aim of this essay was to acquire an enhanced knowledge about young immigrants? point of view of integration. During a former practical training semester I became interested in what the young immigrants thought about their own integration, what their conception was about this issue. I found that it had different meaning to different persons, to some it meant assimilation, to others it meant being able to interact with the opposite gender. To examine this I used interviews and interviewed an amount of young immigrants in different stages of their studies in Swedish.

Syftet med arbetet är att undersöka hur vi idag i Sverige planerar för industrier och verksamheter i anslutning till bostäder, och på vilket sätt detta påverkar samhällsstrukturen. Arbetet syftar även till att åskådliggöra de regleringar och historiska händelser som lett fram till den modernismplanering vi idag ser. Rapporten avser även att ta upp olika tillvägagångssätt att närma sig funktionsintegreringen på och innehåller även ett exempel från Danmark där de försökt ta ett steg närmare blandstaden..

During the three first centuries A.D the cult to roman emperor was practiced over the absolute majority of the known world. It was based on the idea of the deified ruler, where religion was used as a way of legitimizing a social position of an absolute few. It arrived from below but was promoted and spread from above as a way of governmental control. During the same period of time did a new aristocratic social group emerge in remote Scandinavia that eagerly sought new ways to identify themselves and their newly found social standing. With a base consisting of an economic surplus they wanted to create an acceptance for their new way of life and thus in doing so change the very foundation and core beliefs of their own society.The central theme of this study is the cultural exchange that took place between these two cultural spheres and mainly of the effect that the cult to the roman emperor had on the emergence and identification process of the Scandinavian aristocracy..

In the current situation there is not much written about assessment of laboratory work, and the majority of the working physics teachers are retiring and there are only a few newly qualified physics teachers. The purpose of this thesis is to examine how physics teachers assess laboratory work within upper secondary schools, with Gy2011 in mind. The new grade system, Gy2011, has a larger focus on the laboratory work then the earlier system Lpf 94. Skolverket has in their man-ual with examples of assessment two different sorts of laboratory experiments. The first assess-ment is regarding the planning of a laboratory work and the other about how able the pupil exe-cutes laboratory work.

This is a report about accessibility. For this project the accessibility of a building in the city of Halmstad was evaluated. It´s a three storey building with five apartments on each floor divided by two stairwells. These five apartments have since been divided into three different types of apartments. Each type of apartment has been assessed separately.

ABB is one of the world?s leading engineering companies in power and automation technologiesand their solutions improve performance while lowering environmental impacts for energycompanies and industries. ABB FACTS designs equipment and plants for series and phasecompensation.This thesis has been performed at ABB FACTS on the Mechanical Design (DM) department inVästerås, Sweden. The purpose of the thesis was to develop and design calculations andsimulation tools for ABB FACTS?s standard series capacitor platforms.

Akademiska Hus owns and manages the university facilities in most university towns in Sweden. Bilbergska house in Örebro was built in 2008 by Akademiska Hus, and designed by White Architects. Today's buildings must meet accessibility requirements determined by Swedish Board of Housing, and it is the developer who must ensure that they are fulfilled. Swedish Board of Housing requirements are often vaguely written and interpretation space is large.This report aims to investigate how much of the requirements which are set towards the University and landlord Akademiska Hus are being achieved. This is done by studying the requirements that are set.

This study examines whether a spatial relationship exists between blue-green infrastructure and indicators of gentrification in Hisingen, Gothenburg, during the period 2015?2023. Using a GIS-based approach, sociodemographic changes across 83 demographic statistical areas (DeSO) were analysed in relation to six parks established or significantly developed during the study period. Changes in mean income, educational attainment, share of residents with foreign background, and mean age were combined into a gentrification index, which was then tested against distance to the nearest park through linear regression analysis.The results show that socioeconomic changes consistent with gentrification occurred across parts of Hisingen during the period, with the highest index values concentrated in the central and south-eastern parts of the district. However, these changes were geographically selective rather than district-wide.

Should new buildings blend in or contrast from the older buildings around? Could contrasts even emphasize different characters? This report is a discussion on that theme. I´ve studied different architects wiev on the question and studied different of examples of where new buildings contrast to the context in a successful way. In part two I´ve done a proposal on a new housing settlement next to Hammarbyhöjden in Stockholm. The new buildings contrast to the existing and the aim is to emphasize the characters in Hammarbyhöjden as well as in the new structure.
