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.

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.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

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.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

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.

One of the biggest changes which have affected businesses during the last ten years is the accelerating speed at which Internet technology and e-commerce has developed. If Internet earlier was used in the purpose to entertain it is now accepted as an essential business tool and companies are investing more of its resources in e-commerce activities. Everyone ?has to be on the net? today but that implies a challenge in matching e-solutions to the company?s business goals. It is necessary to have clear goals, carry out research and plan a strategy in order to operate an optimal e-commerce website for the company?s needs.The purpose with this dissertation was to see how well companies adjust to new demands in the rapidly changing e-environment.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

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.
