This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..

Illiterata invandrares informationspraktiker

The subject of this two year Master's thesis in Library and Information Science is the information practices of illiterate immigrants in everyday life. The purpose is to examine how immigrants seek, identify, understand and value information sources and information, and how the practices have changed with their arrival in Sweden. It furthermore focuses on the barriers that illiterate immigrants meet in accessing and understanding information. It moreover investigates the strategies they use to overcome them.For this purpose twelve qualitative research interviews were carried out, with illiterate immigrants as well as with service providers. The theoretical concepts of the essay is information practices, which means that the information process is within a context, and information poverty, that people in different context do not have adequate and equal access to information and information sources.Using McKenzie's model of information practices, the essay concludes that illiterate immigrants are active in their information process, especially when they interact with information.

Automatisk räkning med monokrom visionsteknik

The use of vision applications are growing and the demand for integration and connectivity with other industrial automation control devices is increasing. Some businesses that are using vision technology follow US Food and Drugs Administration (FDA) regulation concerning audit trail. This thesis investigates the possibility to use vision technology for counting objects, achieving connectivity and to follow FDAs audit trail regulation. A market survey has been used to select suitable hardware and software to be used in the design of an application that is able to count objects and that uses standard industrial network connection i.e. OPC data access and Microsoft?s .NET components over Ethernet.

Adaptiv temperaturreglering av bostadshus

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Den svenska äldrevården : Behov, konkurrens, kvalitet och valfrihet ur ett fastighetsperspektiv

In this thesis an explorative study was undertaken with the aim to study how a number of private care providers, as well as politicians and officials from councils in and around the Stockholm and Uppsala counties, think about the future of the Swedish elderly care from a property perspective, i.e. homes for the elderly. The analysis shows that there is a demand for capacity in 6 out of 16 municipalities, and that the property is an important part of this capacity, and the fulfillment of it. This was mainly due to the cost of capital, but also because of several other factors such as lack of land, a wish to guide the design, ideology, and in many cases a wish to use the property as an instrument of domination to control private health care providers.Also, the property was show to be connected to economic competition, to freedom of choice, and to quality. The problems related to the property in the market for elderly care still remains to be solved.

Samarbete och nätverksbyggande över kommunens gränser : En studie om Norrköpings kommuns medlemskap i Sweden Emilia Romagna Network utifrån ett aktör-nätverksperspektiv

Social networks have increased significantly during the latest decades, but what does the cooperation include and how does the network processes look like? Networks are not specific for communities in the 2000?s or for that matter human organisations, but the ability to build networks and introduce more actors to the organisation have become easier with today?s communication technology. The study is about the Norrköping Municipality membership in the transnational network Sweden Emilia Romagna Network (SERN). It gives an insight into how networking and cooperation can be seen by politicians and officials, based on mission statements and the reason why a municipality choose to participate in transnational networks. The study aims to examine how Norrköping Municipality uses the SERN network and what the network have resulted in since the beginning of the municipality membership in 2005. It is a qualitative study which involves interviews with officials and politicians from the Municipality of Norrköping and textual material from SERN?s strategy documents and policies.

Nätverk i landsbygdsföretag : fallet Mälarlandet

The interest in companies that are based outside the cities has grown, and many of these companies have focused their activities around service. The countryside companies meet some difficulties in marketing and communication with other entrepreneurs. A network with service based companies in the countryside could help the individual companies to promote themselves and also give inspiration and new ideas to develop their business. The aim of this study is to investigate how a countryside network can be organized but also what conditions is needed to make the network function. The theory is based on a literature study of the three major topics "countryside", "networking" and "marketing".

Al-Qaida - mellan tankeprodukt och reell fiende

The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.
