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.

En litteraturstudie om effekter av fysisk aktivitet på recept av Anneli Björk-Andersson och Jenny Bylund, Institutionen för hälsovetenskap Luleå tekniska universitet. Tanken med studien var att ta reda på effekterna av fysisk aktivitet, hur man arbetar med fysisk aktivitet på recept i Norrbotten samt hur det ser ut i övriga landet. En litteratursökning som innefattade 45 artiklar, rapporter och uppsatser samt fem olika läns landstings webbsidor genomfördes. Några av landstingen har kommit långt i sitt arbete med fysisk aktivitet på recept och eftersom det var lättast att hitta material om dessa valdes de ut. Resultatet var tydligt, man har mycket att vinna på att vara fysiskt aktiv.

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.

Human T-lymfotropt virus (HTLV) är ett C-typ onkovirus som tillhör familjen Retroviridae som huvudsakligen angriper T-lymfocyter och orsakar leukemi och andra autoimmuna sjukdomar. I den nuvarande kliniska diagnostiken används Enzyme-linked immunosorbent assay och ibland vid screeningsmetoden uppträder ospecifika reaktioner. På senare tid har flera metoder baserade på real-tids PCR utvecklats för att bestämma halten av virala genom i patienter. Syftet med denna studie var att sätta upp och optimera en realtids-PCR för detektion av humant T-lymfotropt virus typ-1 och 2. Inför optimering av realtids-PCR extraherades DNA från MT-4 och MO-T cellinjer.  Under optimering av realtids-PCR användes SYBR Green och smältpunktsanalys där flera komponenter bl.a.

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

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).

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.

Stress-related diseases in Sweden have doubled since 1997. Even longterm sickness related tostress has increased over the last decade. In future there is a need of alternative methods todecrease the amount of people being affected to gain a better population health. Natureassisted therapy (NAT) was shown to be a successful method as part of the therapy of stressand burnout likewise was nature an important factor to prevent people from mentaldisorders. The aim of this study was to analyse the latest research concearning nature and itshealth effects with focus on stress and burnout patients in order to plan health promotingactivities outdoors for these patients.

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.

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

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.
