The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

This study addresses mandatory non-trading periods for Swedish stock market participants which have implemented an open-market share repurchase program during the period 2000 until 2010. By locating the date of publication of interim reports, these mandatory non-trading periods called silent periods are examined. The result indicates that repurchase trading activity occurs despite the statutory prohibition. By studying the price support hypothesis assumptions about long- and short-term effect on share price and performance, this study tries to explain these tendencies. An average decline of share price and performance is shown among companies entering silent periods.

In the fall of 2014 a literature review and a scientific study of the topic; "... in the extent to which companies in the industry applies the evaluation of continuous improvement? was conducted at Mälardalen University. These studies are the foundation of this thesis.A strategic improvement is often divided into smaller steps of improvements at each hierarchical level from the top down through the organization. But if there is no response system that can confirm the results of these improvements back through the organization it is very hard to see if the improvements really are improvements or just changes and a waste of resources.

The focus of this study has been to plumb social workers experiences regarding their work methods in two institutions regarding unaccompanied children through a perspective of gender. In this study, four semi-structured qualitative interviews has been contrived in purpose to gather in material which has been presented in five themes to ease an analyse focusing of gender. In all the interviews both authors participated with one in charge and one taking notes. One of the main focuses has been the relations between both social workers and their clients and between colleges in the institutions. The other main focus has been the activities, both planed and spontaneous, which the clients been offered, for example football, bowling and boxing.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

In the political world of today the discussion of Just wars are very present, since the international law and the UN Charter provides certain rules about when it is justified to go to war (jus ad bellum) and how a justified war should be conducted (jus im bello). The discussion about jus ad bellum and jus im bello derives from the theory of Just war. Both in international law and the Just war theory, focus is on interstate wars were the actors are two sovereign states. Since the end of the Cold War there has however been a change in the way wars are conducted. From interstate to intrastate warfare, where the government in most cases no longer has the monopoly over the warfare.According to these facts, my conclusion is that the Just war theory has to expand and incorporate a focus on the human rights in order to be able to meet the new standards of the new wars.

The purpose of this study is to investigate how teachers work with Autism pupils in two different schoolforms: a traditional elementary school and a language school. The study was based on three questions: 1. How do teachers in elementary school prepare, plan and implement reading and writing instruction to Autism pupils? 2. How do teachers in the language unit prepare, plan and implement their reading and writing instruction to Autism pupils? 3.
