The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.

This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

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..

Karriärcoaching är en tjänst som ökat kraftigt på den svenska marknaden. Tidigare studier inom området har visat att en stark självkänsla stärker en persons hälsa och underlättar för denne att hantera problem. Syftet med studien var att undersöka om karriärcoaching har någon påverkan på prestationsbaserad självkänsla, känslan av kontroll (Locus of Control) samt självbemästring av tankar och känslor (Self-Efficacy). Genom en enkätundersökning har en grupp som genomfört karriärcoaching jämförts med en kontrollgrupp som ej genomfört karriärcoaching. Ett oberoende t-test gav en signifikant skillnad i Locus of Control (p<.05).

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This thesis aims to investigate what requirements companies have in order to achieve a successful legislative compliance control. The implementation of an environmental management system can help the company to structure their business and succeed with their environmental legislative compliance.Both small and medium sized businesses perceive that it is difficult and time consuming because the legislation can be difficult to interpret if you do not have the required knowledge. There are many companies that hire help in the form of consultants who audit their compliance, but this leads to a risk that the company will be exposed when the knowledge does not remain in the company if the consultant would cancel the cooperation. There are not so many tools today for businesses to obtain good legal compliance. The methods used are usually checklists included in the control program, and it costs a lot of resources to do everything needed.This study strives to deliver the expressed needs of the businesses.

The purpose of this essay was to sort out parents attitudes concerning children and their use of smartphones, primarily in regards to the integrity-aspect. I have studied if parents believe that their children should have smartphones, if they want to control their use, how they want to control their use and what implications this might have. I've chosen two methods for my research, one quantitative, online questionnaires, and one qualitative, semi-structured interviews. My base has been previous research in the area, to the extent it existed. My findings suggest that parents, on the whole, are positive to letting their children use smartphones but that they?d like some sort of control over their use.

The purpose of this research is to examine the implications of the provisions in the Swedish Code of Corporate Governance (the Code) concerning auditor attestation of the internal control report. We will focus on how the auditors? augmented responsibilities will affect the efficiency in the audit process.Our research indicates that the main benefit from reviewing the internal control report is achieving more reliable internal controls, which results in greater prevention of misstatements in the financial statements. This will affect the efficiency in the audit process since the auditor can place more reliance on internal controls when performing audit procedures. This implies that the benefits of preventing misstatements could outweigh the efforts and resources spent on reviewing the internal control report..

Purpose: The purpose of this paper is to examine if companies? incentive programs for employees is designed in such a way that it makes it possible for managers to reach their goals. Method: Qualitative with a semi standardised questionnaire Results: Our results is that the incentive programs for employees in their present form don?t give the companies a good possibility to effect the employees to perform towards the goals of the system. The performance measures in the incentive programs for employees is suitable in comparison with the goals of the program but the construction and the use of the systems doesn?t give a satisfied result in comprising with the goals.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

Background: Despite the time and money invested in relationships with other companies, it is a fact that many of them fail. Considering this, remarkably little research has been done regarding how inter-organisational relationships are controlled, given that control can function as a solution to the problems involved with collaboration, which arise since such a relation exists in the interface between organisational boundaries, where the companies? often conflicting interests and points of view meet. If one part is stronger than the other in a relationship, the weaker however tends to give way for the stronger?s will.

The purpose of this essay is to examine which factors that influence the design of internal control in municipal context and how well it works. We choose seven municipals, where we interviewed the administrative managers, the chairmen of the committees and two persons of the staff in each activity unit. The interviews were performed by telephone, due to the keeping of the essay?s timeframe.The theory in our essay comprises eight hypotheses. These hypotheses were operationalised into different variables aiming to make statistical tests possible.

Bachelor thesis, Controller, Program of Master of Science in Business and Economics, School of Business and Economics at Linneaus University in Växjö, Sweden, Course Code: 2FE13E:3, Spring 2012 Authors: Jacob Cedergren, Adam Pettersson, Hampus SkelterwijkSupervisor: Anders JerrelingTitle: The ERP-systems impact of the management control - a case study of VIDA AB Original Title: Affärssystemens påverkan på ekonomistyrningen - en fallstudie på VIDA ABBackground: New technology has given businesses new opportunities to use and store information and the current information systems has changed the way of working in more or less all sectors and operations. ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.
