This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

According to science internal communication is a complicated, yet very important, issue of organizations today. An organization with a successful internal communication shows better results both economically and in terms of coworker satisfaction. The two main theories on communication are sensemaking and transmission. After a century with a transmissionary point of view, researchers stress the importance of sensemaking internal communication.Main question of this thesis is ?Which of the two main theories is the most useful when anchoring important messages in large organizations??According to the results of this study, conducted by interviews, neither one is more useful than the other.

This study aims to examine the effect management control systems have on which goals health centers prioritize. The management control systems of one privately owned and one publicly owned health center have been studied through a qualitative case study. Robert Simons (1995) framework with four levers of control (diagnostic control systems, interactive control systems, belief systems and boundary systems) has been used to structure the study. For both health centers we found a conflict of interest mainly between the diagnostic control system and the beliefs system, where the diagnostic control system is biased towards quantitative goals and the beliefs system is mainly biased towards qualitative goals. However, despite the unbalanced levers of control the studied health centers have been able to reach a well functioning compromise between quantitative and qualitative goals..

Syftet med denna uppsats är att beskriva och analysera svenska myndigheters internrevision för att kunna dra slutsatser om i vilken ansvarslinje de befinner sig i dagsläget samt att föra en diskussion kring internrevisionens oberoende. I denna uppsats har en kvalitativ studie genomförts. Med hjälp av semi-strukturerade intervjuer på sex olika myndigheter med krav på internrevision har empiri insamlats som tillsammans med teoretisk referensram ligger till grund för analys och slutsatser. Studien visar att svenska myndigheters internrevision befinner sig i den tredje ansvarslinjen. Vissa variationer inom den tredje ansvarslinjen kan urskiljas på grund av dels otydliga riktlinjer för internrevisorerna för att kunna bibehålla ett oberoende i samband med råd och stöd och dels på grund av bristfälliga kunskaper i den andra ansvarslinjen avseende hur ansvaret ska fördelas. .

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.

Audit is a common concept in Sweden. This occurs in many contexts and situations and may intend a wide spectrum of areas. It might consider environment audit, amateur audit, internal auditing, external audit etc. In the business community external audit and the associated external auditor is possibly, from the general public's side, the most recognized. The external audits purposes in big features are checking limited companies economic accounting along with the board and CEO: s management.

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

The main purpose of this essay is to through theories about internal communication, channels to communicate through and change management study how these can be related to the processes at the Swedish Consumer Agency due to its future relocation. The main question within this essay is therefore:- How has the internal communication and the change management at the Swedish Consumer Agency developed in comparison with the prescribed theories?This essay is divided into three different parts (ideal, reality, ideal/reality) which can be derived to the essays theory, result and analysis chapters. The theories are the ideal while the result describes the internal communication and the change management during the process (the reality). In the analysis chapter, the ideal and the reality are compared to distinguish how the reality has been working in comparison to the ideal.The internal communication has mainly been distinguished through the authority?s intranet and the information communicated has comparatively been fast, open, objective and reliable.

The effect of the salary system and age on the internal and external motivationThe purpose of the study was to examine how a fixed salary with commission and only a fixed salary, and age affect the internal and external work motivation of sellers. This was studied by a questionnaire and participants were sellers in the call center industry in Sweden. In total there were 112 sellers from nine different companies that responded to the survey. The respondents were divided into groups based on pay systems and age. The measuring instrument used was the Work Extrinsic and Intrinsic Motivation Scale which classifies the motivation of internal and external based on six subscales.

AbstractTitle:A study of the internal communication at The Swedish Department of Taxes (En studie av den interna kommunikationen på Skatteverket)Number of pages: 36 (52 including enclosures)Author: Emma KreüTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Atumn 2006University: Division of Media and Communication, Department of Information Sciense,Uppsala UniversityPurpose/Aim: To resarch the internal communication within The Swedish Department of Taxes and the relationship between information sender and reciver.Material/Method: By contedning critical discourse analysis on The Swedish Department of Taxes? policy for internal communication and accomplish interviews with co-wokers in position of reciving information, in position of sending information and section managers.Main Results: The co-workers in position of reciving information felt they had a good communicational relastionship with their closest section manager, but not with the upper management.Keywords: Internal communication, communicational leadership, organizational communication..

The purpose of this thesis is to find means of control that secure cost efficiency regarding the accommodation for the employees on missions abroad of the Swedish Ministry for Foreign Affairs. Today the ministry?s cost for the employees? rented housing is 100 million SEK and there is a need of improvement in the control of these costs. A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.

I denna studie har undersökts personlighet och Health Locus of Control hos 56 kvinnor och män i åldrarna 18 till 65 år, där 30 var svenskar och 26 var tyskar. Undersökningens frågeställning var: Är en eller fler personlighetsdimensioner i Fem-Faktor-modellen relaterade till i vilken utsträckning en individ har Internality, Powerful others eller Chance Health Locus of Control. En NEO-PI enkät och ett Multi dimensionella Health Locus of Control-skalan-formulär administrerades. Resultatet från undersökningen kunde påvisa en signifikant korrelation mellan Openess to Experience och Powerful Others Health Locus of Control samt Conscientiousness och Powerful Others Health Locus of Control. En signifikant skillnad mellan svenskar och tyskar beträffande Powerful Others kunde också påvisas.

The aim of this study is to gain knowledge about the internalcommunication at a public library in Sweden, focusing on the flow of information and the library employee?s role as a source and receiver. This is an important subject because internal communication affects not only the internal work, but also the users. Despite this there are few studies about internal communication in libraries. The research questions used are: How do the employees perceive the role as source of information, and what choices do they make before they spread information? How do the employees perceive the role as receiver of information? How do the employees feel that the information flow works in the organization as a whole?The research is founded on five qualitative semi-structured interviews with the library employees.

The Swedish bank Handelsbanken has, according to their own way of measuring, been more successful than a weighted average of their competitors during the last 38 years. They have also handled the recent financial crisis, as well as the one in the 1990´s, better than most other banks. This paper studies their management control system at branch level in order to identify the controls which have been enforced to ensure that a low risk level is retained in the lending. The controls that have been identified are; (1) A decentralized organization with the offices as profit centers where the manager has restrictions regarding risk level and the results are measured as K/I (cost/revenue). (2) The absence of bonuses and individual follow-up regarding performance measurement.

This thesis is about the effect of political efficacy on societal participation among youths aged 15 to 29. It takes a starting point in the gloomy view of the decline of political participation among citizens in the western world, especially pointing out youths as a threat to democracy. This is a broad subject to take on so my aim becomes a bit more specific. The aim of the thesis is therefore to investigate if belief in ones own capacity and in the responsiveness of the political system affects the actual participation among youths in Europe, independent of a set of alternative predictors. Moreover the thesis is divided into two sub-investigations, one qualitative and one quantitative.
