The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.

The public relations business has grown from almost nothing to a large international industry the last decades. Throughout the history the industry has struggled with a lot of critique and public relations has become a negative symbol for manipulation of information. Because of this negative view of the industry and the medial change taking place, the purpose of this study is to investigate how two different generations think about public relations. More accurate, the study will through a qualitative interview study explore how young people from a highschool in Luleå and elder people from Luleå township thinks about pubic relations, and most imortant why they have this particular view. By creating four focus groups, two with men and two with women, this also enables a comparative study between the gender. The focus groups were later analyzed and compared to two selected groups of theories on public relations, the theories were positive and critical theories compound in two categories.

Den ha?r a?r en kvalitativ studie som presenterar resultatet fra?n fem semistrukturerade intervjuer med fem ungdomar mellan a?ldrarna 19-25 som bor i Lulea? kommun och som inte ga?tt fa?rdigt gymnasiet. Syftet med studien a?r att underso?ka ungdomarnas upplevelser av att avsluta sin gymnasieutbildning i fo?rtid, samt ta reda pa? vad som pa?verkat deras beslut att go?ra det. Till grund fo?r analysen ligger Bourdieus begrepp kapital, habitus och kulturell reproducering samt artiklar och tidigare forskning som ses relevanta fo?r studien.Resultatet visar att alla ungdomar, fo?rutom en, genomga?tt en separation mellan fo?ra?ldrarna na?gon ga?ng under barndomen.
