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.

Scania Top Team is a competition where the best mechanics in the world are competing against each other. In 2011, the world final was recorded and this material is now used to see which problem solving strategies these top of the line teams are using to solve the realistic problems assembled in front of them. To help them, the mechanics are allowed to use two of Scanias IT-systems: Scania Multi and Scania Diagnose and Programmer 3. This report consists of two parts. The first part is the development of a method to analyze the recorded material.

In organizations today Corporate Social Responsibility (CSR) is becoming a common means to try to gain legitimacy and credibility for their business. A successful CSR strategy has the potential to generate positive outcomes for a company and reaching out to stakeholders about the corporation?s contribution in the field is an important part of the work. In this study I examine how the employees at Max Hamburgare receive the corporation?s efforts within sustainability, how it is perceived and what this means to the employees.

The management of assets in organisations today can be a challenging task and optimising their usage is critical to ensure maximum profit. For rental businesses offering tangible products efficient management of movable assets are an essential part of the business strategy. The main purpose of this study is to investigate how asset management and asset information management can be carried out in rental businesses and in what ways information technology can support it. By doing a literature review combined with a case study where three rental businesses and their use of information technology were examined we could identify several important aspects regarding asset information management. The results we have found is that rental businesses with a high degree of digitization in existing asset information management systems are able to rationalize existing work processes, which in some ways changes the roles of employees.

Denna utredning har gjorts för att genomlysa en teknik som går under namnet JavaTM 2 Micro Edition (J2METM). Vårt mål var att grundligt belysa tekniken och tanken bakom J2ME samt att visa på för- respektive nackdelar med tekniken avseende prestanda och säkerhet. Ett annat mål med utredningen var att visa på praktisk användbarhet av Java i mobiltelefoner och konsekvenser på den mobila infrastrukturen. J2ME är en plattform skapad för att tillmötesgå behoven från den snabbt växande marknaden av produkter som försetts med processorkraft. Dessa datoriserade enheter är mindre än traditionella bordsdatorer och har därmed en annan typ av fysiska begränsningar i form av t.ex.

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

SammanfattningAnalysen undersöker meningserbjudandet gällande konsumentfrågor i tre läroböcker inom hem- och konsumentkunskap, med utgångspunkt i kursplan 2000 (Skolverket, 2000a). Först definierades och avgränsades konsumentfrågorna med hjälp av konsumtionsprocessen (Bjurström, 2004, McGregor, 2011a). Det andra steget i analysen var att kategorisera det befintliga konsumentinnehållet utifrån tre undervisningsstrategier: fakta-, normerande- och pluralistisk undervisningsstrategi (Skolverket, 2002, Kronlid & Öhman, 2010). Som ett tredje steg genomfördes en analys även av kursplan 2000, med hjälp av de tre undervisningsstrategierna. Detta tredje steg utgick ifrån antagandet att läroböckernas legitimitet och relevans styrs av kursplanen (Sellander, 1988, Lundgren, 1989, Englund, 2011).

The purpose of this study was to examine how commitment to a cause on a local basis had developed in four smaller groups during one decade. In 1996 I interviewed representatives in Åsele, Borrby, Hasslarp and Tving about their commitment and citizen initiative. Now, ten years later, I followed it up by interviewing them again. I wanted to know if the groups/associations still existed, if they had achieved their goals as they where pronounced ten years ago and how a strong commitment on a local basis can develop during ten years. Which phenomena decide whether the group develop or phase out? I use the term citizen commitment instead of citizen initiative to stress the fact that it is no longer an initiative but an on-going commitment.

This essay aims to investigate the use of an origin-ID within the Beaker Complex, as defined by John C. Barrett, seen through their different expressions of use in ceramic form and ornamentation, architecture and landscape through time and space with special emphasis on the late Neolihtics in the South of England. The analytic vehicle "the reinforcing circle" is used as a new diffusion model suggested by Stuart Needham, and the analytic tool "incubation" is used to structure the process the Beaker-cultures may have used to reach cultural hegemony. Id est, that the Beaker-cultures socially invites already existing cultures, offering within family and trading the results of new technolo­gies. And/or, occupy the space and use the authority needed by re-writing the narrative as seen in the grave use and grave deposits.

New laws and recommendations within corporate governance during the last years have affected the way board of directors work. The board is said to have and fulfill three roles: a control role, a service role and a strategy role. These roles could be understood by three theoretical theories: the agency theory, the resource dependence theory and the stewardship theory. The purpose of this study is to investigate whether, and if so how, the board work differs between two small firms based on these roles, given that one of the firms is a publicly listed firm and the other is a privately owned firm. Using a qualitative case study as research method we find that the board work differs between the two companies when it comes to these roles.

This thesis examines the verification of the terms and conditions stated in contracts based on the Public Procurement Act. In March 2013 the Swedish state procurement commission released " Good Business - A Strategy for Sustainable Public Procurement " (SOU 2013:12), which found that the proportion of control and verification is relatively low. The thesis examine how verification is carried out and looks for an explanation to why verification is not more oftenly performed. To answer these questions two care studies, based on seven semi-structured interviews, is presented as the empirical material. Network theory has been used to analyse the empirical results, and aspects of commonly used theories such as contract management and "Markets and Hierarchies" by Williamson has also been taken into account.

This paper aimed to investigate to what extent there is an age cut-off for teenage boys in the women?s shelters of Sweden and how a possible cut-off is described and maintained. This occurrence has not been investigated earlier to a large extent, which emphasizes the importance of this paper. A mixed strategy was used to cover both the frequency as well as the explanations to the age cut-off. The quantitative survey was sent to all women?s shelters in Sweden and the result showed that 56 % of the shelters had an age cut-off for teenage boys from 12 years of age and above.

The purpose of this study was to elucidate how individuals diagnosed with Aspergers syndrome experience stigma as a result of their diagnosis. The paper was based on a qualitative method, consisting of six interviews with booth male and female participants. We took part of previous studies and research as well as existing theories on the subject, in addition to the analysis of our empirical material. Significant in this study was that all participants were relieved when getting the diagnosis, as they finally got an explanation for what was wrong. The results indicated that the majority of the informants felt worried of the possibility to experience stigma and discrimination, which resulted in that the majority of the participants tended to use an avoidance coping strategy.
