In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

The purpose of this essay is to examine for the age discrimination towards older people in the working life. The essay practice EU-law and national law to examine the age discrimination. It also looks for the limits towards age discrimination. A presentation of the rules will make it easier to see how employers are possible to get around the ban against age discrimination. This essay also illustrates how age discrimination emerges in recruitment processes and then how to discourage age discrimination.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

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.

Aligning parallell terms in a parallell corpus can be done by aligning all words and phrases in the corpus and then performing term extraction on the aligned set of word pairs. Alternatively, term extraction in the source and target text can be made separately and then the resulting term candidates can be aligned, forming aligned parallell terms. This thesis describes an implementation of a word aligner that is applied on extracted term candidates in both the source and the target texts. The term aligner uses statistical measures, the tool Giza++ and heuristics in the search for alignments. The evaluation reveals that the best results are obtained when the term alignment relies heavily on the Giza++ tool and Levenshtein heuristic..

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
