Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

De mänskliga rättigheternas beskyddare
The Human Rights claim that all humans have special rights that are not allowed to be broken or violated. Although these rights are broken and violated by states every day. One major fact that makes this possible is the principle of sovereignty that includes all states, and which says that every state has the power and right to make decisions and create laws within the own country without the interference of other actors. In other words, the problem is that the states have to much power in relation to actors usch as the United Nations and to the rules of the Human Rights. This essay describe a possible way to strengthen the power of the Human Rights so that all humans can be guaranteed the fulfillment of the rights..

Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar
The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

Interorganisatoriska relationer i filmbranschen: En fallstudie i samproduktioners påverkan på svenska
This paper investigates and explains the existence of different governance structures in the Swedish film industry. Using a theoretical framework of transaction cost economics, it is shown that trust follows from frequent production projects, affecting the distributors? control of producers, cinemas, video retailers and television. Control becomes more flexible, informal and less time consuming. Furthermore, the control of the distributors? relationship with television and cinemas proves to be multidimensional and affected by transaction activities, as well as by demands from previous parties in the value chain.
"Vi kunde ha varit bättre..." : En fallstudie om internkontroll i Sverige
???This study has been made with the purpose of gaining an understanding of how a Swedish company may think and act concerning their internal control. An American body, COSO, have for some time published documents containing guidelines for how companies should go about this process, however, when conducting this study we were not aware of the extent to which companies in Europe and mainly Sweden used them. In order to learn about this, and also to gain an understanding of when these guidelines are appropriate, we conducted a case study with a large-sized, multinational Swedish company. We also conducted an interview with an expert in internal control monitoring, Anna-Clara af Ekenstam of Pricewaterhouse Coopers, in order to get the perspective of the evaluators in this process and to gain some insight as to whether our case is typical in Sweden or not. We found that our company disregards certain aspects of internal control condoned by COSO, while performing better on other dimensions.
Den moderna flerenhetsfranchisetagaren: En studie i utformandet av kontrollsystem hos växande franchisetagare
Franchise theorists have to a large extent failed to keep up with the actual development in global franchise chains. The recent emergence of fast growing multi-unit-franchisees has fundamentally been ignored, and it has been claimed that the new phenomenon can be regarded as a mere replication of the franchisors? structure and control system into sub hierarchies. This study however, suggests that the reality is more complex. Through conducting case studies of two Nordic multi-unit-franchisees, new theories are built explaining how and why control systems are designed the way they are.
Struktur och styrning med balanced scorecard som styrverktyg : En studie inom Västra Götalandsregionen
BackgroundThere are different organizational structures and control and it has been proved difficult to find a combination between these that leads to goal congruence and improved efficiency. An organization can be structured according to hierarchical levels and the decision making can be either centralized or decentralized. Organizational control can be classified according to the amount of rules and balanced scorecard can be used to weld together the structure with the control.PurposeThe purpose is to create an understanding of how two types of structures and control in an organization appears and also to investigate how these differ from one another concerning the balanced scorecard as a control system. We will also investigate how the variables goal congruence and efficiency are affected by the implementation of the balanced scorecard.MethodTo answer the purpose of this thesis we have mainly used the qualitative method since we have studied two organizations thoroughly through interviews on different levels of the organization. The study also has some quantitative elements since we wanted to get a more truthful picture of the organizations.
Kulturella och ekonomiska överväganden för framtiden : En fältstudie om syriska flyktingar i jordanska värdsamhällen
This thesis examines the everyday resistance, and its interaction with cultural hybridity, of the Saami population in the administrative unit of Torne lappmark during the period 1639?1732. To do this, the thesis uses theoretical concept of everday resistance as it has been described by JamesC. Scott and the theories of cultural hybridity as they have been described by Peter Burke. Primary source material used in this thesis consists of the court records from Torne lappmark, specifically from the courts at Jukkasjärvi and Enontekis.The results of this thesis present a picture of the everyday resistance in early modern Torne lappmark.
Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar
During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..
