Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
Prognostisering av räntabilitet på eget kapital - Förbättras möjligheten att prognostisera räntabilitet på eget kapital om hänsyn tas till earnings management
Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.
Äga eller leasa lagret i ett mindre handelsföretag?
Small companies have fewer resources which often result in an tendency to disregard administrative tasks. A factor that influences the company?s revenues is the control of its inventories. The purpose of the current study was to analyze which of the two options, leasing or owning your inventory, that could be justified from an economical perspective. Furthermore, the purpose was to describe the optimal inventory level for each option. To meet these objectives representatives for the company was interviewed and a thorough investigation process was undertaken, during which methodological problems were solved. It was found that leasing the inventory was the most expensive option for the company. Analysis demonstrated that optimal turnover inventory according to EOQ (Economic Order Quantity) would amount to 65,0 thousand Swedish Krona if the company leases their inventory in comparison to 56,0 thousand Swedish Krona if the company owned their inventory.
Rekreationsanpassad skötselplan för Skedalaskogen :
In this master thesis we suggest a recreational directed forest management plan for the
Skedalaskogen. The forest is situated 10 kilometres east of the city of Halmstad and is owned by the municipality.
We have in literature and in research investigated what people like and want in the forest, how to manage the forest for recreation according to for example tree species, mixtures and density. We tried to adapt the forestry methods more to recreational thinking. We have also looked at issues like what is rare and not rare in this part of the country according to nature and forest, where people live and which connection they have to the Skedalaskogen.
The Skedalaskogen is a quite big area, totally 830 hectares. The area have about 100 000
visitors a year.
ATP bioluminescence to establish a test procedure for hygiene testing of liners and tubes on farm level : an investigation of the effect of ageing on the hygienic status of rubber liners and tubes
When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.
Koalitionsbildning och Fragmentering. En studie av koalitionsbildning i kommuner med fragmenterade partisystem
During the last decades the Swedish local party systems have gone through some considerable changes. The number of parties present in local party systems have increased and in some cases even doubled. This makes coalition building between parties complex and parties will be forced to rethink their coalition strategies and adjust to the new circumstances. Theoretically, coalition building has often been considered and applied to national data and there have been just a few attempts to develop and theoretically explain coalitions on a local level. Thus the aim of this paper is to use different theoretical approaches to local data to test the significance of traditional coalition theories.
Utfodring och hälsa hos privatägda ridhästar :
The aim of the study was to investigate feeding routines, management, health and level of activity of riding horses in Sweden. This was obtained by a survey requesting information from owners who kept horses at a non-professional level. Owners to approximately 500 horses were contacted and the usable response of the survey was 56 %. The dominating breed in the study was Swedish warmblood (38 %). Fiftytwo percent of the horses were geldings, 45 % were mares and 3 % were stallions.
Äldre militärteoriers giltlighet imodern sjökrigföring
The amounts of theories that deal with naval warfare are many. Several of those are developed under the previous century when tactics and technology were in the eve of development. Many of modern thinkers within science of war often refer to older but recognized theories. The purpose of this essay is to examine if the old but recognized theories are of current interest in modern naval warfare. The questions that are used in this essay are, what is the characteristics of the war of Yom Kippur with Mahan?s offensive and Corbett?s defensive as a starting-point and are there any of the theories that are prominent.
Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud
The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long
time. Electronic Data Interchange (EDI) is used to transfer different business
documents from one company to another. This is done in such way that the
information itself is separated from how this information is stored and handled
in the companies internal systems. As different companies have different
systems there is a need for a standardised format for this exchange.
There is a big difference between EDI-systems based on what kind of
EDI-standard is used. The most common standard in Europe is EDIFACT, but with
increased interest of using the Internet for business communication there is a
need for a standard that is adjusted for use over the Internet.

Anonyma Alkoholister : Vilken inverkan självhjälpsgruppen har på gruppdeltagarnas välbefinnande
AbstractWe are interested in group meetings of the self-help group Alcoholic Anonymous and the emotional energy created therein. We examine which impact self-help group AA has on its group participants regarding: group meetings, dealing with alcoholism and identity. Group membership has great value for individuals; it provides social identity and possibility to self-value. Previous research shows that group members of self-help groups who have been sober for a period of time experience higher self-esteem and less anxiety compared to non-members. Our thesis is based on a hermeneutic approach.
Muntlig formativ kamratbedömning som kommunikativ praktik : En designbaserad studie i det naturvetenskapliga klassrummet
In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.
Konsekvenser av principbaserade regelverk: En studie av säkringsredovisning på en svensk storbank
IASB is currently working with the replacement of IAS 39 Financial Instruments: Recognition and Measurement. The new standard IFRS 9 Financial Instruments is said to be based on principles as opposed to the more rules-based IAS 39. This thesis examines the third phase of the project regarding micro hedge accounting. The expressed goal from IASB is to provide more useful hedge accounting information by reducing complexity of the standard. To examine the potential effects of the transition from the rules based IAS 39 to the more principles based IFRS 9, we have performed a case study on a major Swedish bank.
?Vi fixar och trixar oss fram till att hjälpa människor?: En studie med fokus på det sociala arbetet med köpare och säljare av sexuella tjänster i Sverige i relation till mänskliga rättigheter.
The thesis ?Vi fixar och trixar oss fram till att hjälpa människor? focuses on social work in the field of prostitution and human trafficking in Sweden. Through semi-structured interviews with social workers in the municipalities of Stockholm, Göteborg and Malmö working with persons selling and buying sex, and through discourse analysis, the author analyses the perceptions among these social workers of the relation between human rights, prostitution and human trafficking, and the social work which they conduct.The thesis concludes that although the social workers perceive prostitution and human trafficking and social work in this field as human rights related, they are not explicitly using a human rights based approach in their work.The thesis concludes that the social workers identify several aspects that infringe on the rights of their clients in relation to the human rights principles of Universality, Non-discrimination, Accountability and Rule of law and the principle of Participation and Inclusion. They portray the human rights situation of street based sellers, especially those not being Swedish citizens and those affected by human trafficking, as severe.The thesis concludes that the social workers find several obstacles (legal as well as structural) that diminish their ability to strengthen their clients? human rights situation.
