Background: Many companies have outsourced their IT-operations and their expectations of what this IT-outsourcing will contribute to the business are high. Cost cuts are not always a natural outcome of IT-outsourcing. Many companies that have outsourced their IT-operations consider it to be problematic and complex to exercise management control and reach cost control which was the purpose of the IT-outsourcing. Purpose: To describe and analyze what affect IT-outsourcing has on a company?s management control system and a company?s possibility to exercise cost control.

The change of control clause is nowadays a well used covenant in the Eurobond market, with the aims to protect bondholders in case of a leveraged buyout. This thesis intend to evaluate whether the change of control clause is a new phenomenon in the Eurobond market today and to estimate what have been the driven force for the popularity of it. The thesis found that the change of control clause already existed before and thus it is not a new phenomenon. Several factors where found though to explain the extended use of the clause today. Starting in 2005 the LBO activity increased rapidly, exposing almost every company to the risk of LBO.

Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Ett högt ohälsotal i arbetslivet innebär stora kostnader för samhället, arbetsgivare och även för de anställda. Forskningen inom detta område har flyttat fokus från att studera ohälsa till att istället studera hälsa och vilka faktorer som befrämjar hälsa i arbetslivet, de så kallade friskfaktorerna. Föreliggande studies övergripande syfte var att studera om upplevelsen av organisationsrättvisa och personlighets¬faktorn work locus of control predicerar upplevd hälsa hos kollektivanställda män och kvinnor. Studien genomfördes utifrån ett kvantitativt perspektiv med 103 deltagare som besvarade en enkät. Svarsfrekvensen var 22,5 % och resultatet visade att work locus of control predicerar upplevd hälsa för männen och procedural rättvisa predicerar upplevd hälsa för kvinnorna.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

Mergers and acquisitions are common phenomenon in today´s society in order to increase shareholder value. Two years ago a fusion of Sweden´s two largest companies in the industry of real estate took place and even though three out of four mergers and acquisitions financially fail this certain case turned out highly successful. The aim of this thesis is to examine how the organizational structure and the management control have been designed and characterized the organizational performance and furthermore what are the success factors of the integration. By studying an acquisition and its potential effects on organizational structure and management control parallel to a model that describes the best practice guidelines for managers to successfully deliver value from their acquisitions, it can be shown that an acquisition has direct effects both on the acquirer and the acquired company and thus the new organizational structure. The main results, thus, is that through active leadership, increased specialization, and more decentralized and thus efficient management control a new organization has emerged consisting of the best features of two separate worlds..

Municipalities must establish budget annually but they are free to decide how the governance should be designed, this can lead to lack of consistency and measurability within and between municipalities. The purpose of this thesis was to present a proposal for a unified and more measurable financial structure of a municipality where this was lacking. In our theory we describe the issues of traditional management control and we introduce an alternative control with non-financial ratios included, called the Balanced Scorecard. In the empirical data it is investigated how the governance of a municipality could be designed, according to the respondents. In the analysis the information gathered to reach the answers to what are considered to be useful governance in municipality, are examined. In the conclusion, we design Balanced Scorecards with both financial and non-financial ratios to the councils of the municipality..
