The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

Företags samhällsansvar (Corporate Social Responsibility, CSR) är ett väl debatterat begrepp som uppmärksammats allt mer i bland annat media, men även av företag. Däremot är begreppet konsumenters samhällsansvar inte lika uppmärksammat trots att det finns en interaktion mellan konsumenters- och företags samhällsansvar. Forskare framhåller att det finns bristfälligt med teorier om konsumenters samhällsansvar samt att definitionen är viktig för att fortsätta driva CSR-debatten, vilket gör ämnet relevant att studera. Studien syfte är att med utgångspunkt i samhällsansvarsmodeller på företagsnivå, utveckla en definition och en tentativ samhällsansvarsmodell på konsumentnivå. Slutsatsen baseras på en kvalitativ undersökning utifrån 15 intervjuer samt teorier som behandlar definitioner och modeller om samhällsansvar.

The aim of this paper is to critically examine and analyze how the informal performance about masculinities and femininity are being expressed and produced by the text and pictures in Huddinge kommuns internal magazine for the staff working within the public administration. The concrete questions are:By which patterns constructs the performance of gender in Huddinge kommuns internal magazine for the staff working within the public administration?Are the femininity and masculinities being expressed in a static way or have it changed in Huddinge kommuns internal magazine for the staff working within the public administration throw the examined years 1985, 1995 and 2006?A quantitative and qualitative method is used. The point of departure is organization theory in a gender perspective. With the gender organization theory we examine the structures, leadership, symbolics and changes through the examined years.

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

 Abstract Study: Degree project in teacher education, Advanced level, 15hpUniversity of SkövdeTitle: A study on students' self-esteem Students' statements on the encouragement and support in a sixth gradeNumber of pages: 26 pagesAuthor: Marie Agapuu & Ingrid SvenssonTutor: Anna-Stina AhlrikDate: January 2009 Keywords: Self-esteem, encouragement, support  A good self-esteem of students will often coincide with good academic performance, but it has also shown that students do not have low self-esteem due to low academic performance. Students' self-esteem is both a complex topic and concepts. We want this study to draw attention and to discuss teachers' efforts to enhance students' self-esteem in school. Encouragement and support of the school adopted in the study contribute to strengthening students' self-esteem. The study examines whether and how nine pupils in a sixth class is that they get encouragement and support of / from their teachers in school subjects and in learning situations.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

This bachelor thesis examines the relation between countries? degree of economic freedom and their economic performance. Economic freedom as a concept is defined as the degree of market economy within a nation.The variable of measure that is used is the Frasier institute Economic freedom of the world index (EFI). The paper is built upon the Solow growth model and is extended by incorporation of additional variables; among which of course economic freedom. The study is performed through regression analysis, based on the neoclassical model both on rich countries, poor countries and on all investigated countries.Two investigations are performed: i) the impact from economic freedom on countries level of GDP per capita and ii) the impact from economic freedom on the growth rate in GDP per capita.The finding is that economic freedom can be seen as a relevant determinant of differences in GDP per capita growth rates between nations.

This study deals with sustainability reporting in three governmental and three non-governmental Swedish companies in different industries. With increasing demands from the society regarding company?s CSR - Corporate social responsibility, the perspective of accounting gets broader and covers even non-financial information to meet not only the owners? demands but also others stakeholders' requirements. Sustainability has become an important tool for creating company?s business value and a positive sustainable external image.

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.

Syftet med uppsatsen är att studera varför och hur företag arbetar med CSR, samt hur detta arbete kan redovisas. Vi har gjort en kvalitativ undersökning med utgångspunkt i fyra företag i olika branscher, Trelleborg AB, Green Cargo, Vattenfall och SAS. Vi har även intervjuat en revisor och en konsult inom CSR-området samt gjort en attitydundersökning med hjälp av enkäter.CSR står för Corporate Social Responsibility och handlar om det ansvar som företag har gentemot samhälle och miljö. Det är ett brett begrepp som innefattar många olika aspekter och uppfattas olika i olika sammanhang.En anledning till att företag arbetar med CSR är att intressenter så som kunder, ägare, media, intresseorganisationer och myndigheter med flera påverkar och ställer krav på företag. Kunder kan välja bort produkter som inte anses vara producerade på ett ansvarsfullt sätt och kan bojkotta företag som inte tar sitt ansvar gentemot omgivningen.

As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM).In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature.

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

This study aimed to explore how 31 collage students' cognitive performance and their ability to create false memories were affected by the exposure of an extraneous background noise. The studies main hypotheses were based on previous research on how extraneous noise affect the cognitive ability and the creation of false memories: 1) that an extraneous background noise increases the ability to create false memories, 2) that an extraneous background noise impairs the learning of cognitive information, 3) that an extraneous background noise contributes to an increased representation of fictional words, 4) that an extraneous background noise impedes the ability to understand speech . The results showed a tendency in which false memories increased in the condition without background noise, a result which goes in the opposite direction of the hypothesis. Furthermore, the result supported the hypothesis that the extraneous background noise impairs the learning of cognitive information. The results also showed that there was no effect between the conditions regarding the representation of fictional information.

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.
