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.

Synligt- och osynligt stöd. Anhörigas upplevelser av stöd när en familjemedlem vårdas i sen palliativ fas.

When a family member is being cared for in palliative care relatives often need support to be able to support their family member. The purpose of the literature review was to illuminate the nursing staff?s support from the relatives? perspective when a family member is being cared in a late palliative phase. The study is a literature review, there already existing research are surveyed. The findings were structured into two parts, tangible- and the intangible support.

Frånluftsvärmepumpens möjligheter i flerbostadshus

If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.

Utvärdering av responsiv design : En kvalitativ användarstudie av responsiv webbdesign för utvärdering av Hi-Fi prototyp

In my study, I have chosen to examine how the user interface and content must conform to design guidelines for responsive design makes it suitable for diverse desktop environment and for varied mobile platforms. The purpose of this study is to examine the extent recommended design guidelines based on scientific research has a positive impact on user performance and perception when using this study delivered hi-fi prototype. The goal of this study is to provide a Hi-Fi prototype with high usability that will introduce and inform the public about BrasilCine according specifications. Study findings from user testing and supplementary questionnaires show that the implemented technologies as design guidelines for responsive design and design features have a positive impact on user performance and perception. The study results are therefore relevant for further prototype development..

Dramat i musiken

The aim of this master?s project is to explore ways to perform piano music conceived dramatically. I do this through performance of Beethoven?s Appassionata Op. 57 and of Scriabin?s Piano sonata no.

Perioperativ trycksårsprevention - en litteraturstudie om operationssjuksköterskans skyddande åtgärder

ABSTRACTPressure ulcers are a serious health damage that causes great suffering, prolonged hospital stays and increased health care costs. Patients undergoing surgery are at high risk of developing pressure ulcers and it is the operating theatre nurse responsibility to protect against health damage through nursing. There are little research made in the area of perioperative pressure ulcer prevention. In order to investigate perioperative pressure ulcer preventive care measures that are described in the litterature and to answer the question how the operating theater nurse can protect the patient, a pilot study of a systematic literature review was carried out. Data base searches were conducted in PubMed and Cinahl from where ten articles were selected and examined for their quality and content.

Testramverk för distribuerade system

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Livskvalitet hos personer som genomgått en total höftledsplastik - en litteraturstudie

The purpose of the study was based on scientific literature to describe the quality of life of persons who have undergone a total hip replacement. The method was a descriptive literature review. The results showed that pain was the most obvious change after surgery. Mild pain before surgery was strongly associated with mild pain after surgery. But despite less pain were experienced early, it took 1 year to achieve the full benefits of improved physical function.

Effektiv försvarslogistik?

Försvarets materielverk (FMV) står inför en omfattande ominriktning av verksamheten med tillhörande omorganisation. Den nya verksamheten innefattar att leverera tjänsten försvarslogistik till Försvarsmakten (FM). Då det inte finns någon entydig definition för vad försvarslogistik är så har detta arbete inriktats att utarbeta ett förslag till en sådan definition. Dessutom har en procedur skapats som identifierar relevanta prestandamått för ett godtyckligt försvarslogistiskt system, s.k. Key Performance Indicators (KPI), som kan användas för att påvisa om försvarslogistiken är effektiv eller inte.

Gränsöverskridande föreställningar : En analys av dansperformance utifrån tre exempel

The essay is an effort to examine and define three examples of liminal dance performances through an aesthetic, hermeneutic and semiotic analysis. The examples are three dance or liminal performances, made by three different choreographers and performed at ?Moderna Dansteatern? and ?Dansens Hus? in Stockholm during September and October 2005. In the effort to determine the liminal and cross-over in the performances, the analysis focus on aspects such as: the character of the work, choreography, the use of scenery, stage light, requisites, conception of place and interior room, the use of costume and mask, the use of different media as text, pictures, film, and music or not using any these, and the interaction with the audience. The analysis depends on a historical background and the use of literature in the subject.

Examenskonsert

In this essay I analyze the performative aspects relating to Marina Abramovi?'s The Artist Is Present, which took place in spring 2010 at MoMA in New York, from the context of the artist and work, institution and documentation. In this performance work, for the duration of the exhibition, Abramovi? sits completely still opposite another chair where anyone from the audience may sit. The art arises through this participation.

Hypotermi vid anestesi av hund

The reasons for hypothermia during general anaesthesia are many and varied. The lowered body temperature causes negative physiological effects and leads to discomfort for the animal during the recovery period. This student report is a combination of field study and literature review. In the field study the changes in ambient temperature and the rectal temperature of dogs were monitored during general anaesthesia. The purpose of the study was to see if the body temperature of dogs was reduced during general anaesthesia.

Relationen mellan prestationer och ersättning

The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer. The purpose of the thesis was to examine the link between CEO compensation and corporate performance measured as a change in Market to Book ratio. Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.

Organisationskulturs inverkan på kunskapsdelning: en forskningsöversikt

A research review shedding light over organizational cultureand its affect on knowledge sharing. The purpose of thereview was to give an overview of the current researchmeanwhile answering the research questions how and whyorganizational culture influences knowledge sharing.Through careful selection of articles, from Journal ofKnowledge Management, a review of the material led toareas of emphasis being identified: motivation, trust,organizational structure, management, communication andrewards. For each area of emphasis the results from thechosen articles were presented and analyzed, leading toconclusions that the how and why of organizational culture?sinfluence is due to mainly individual motivational factorsamongst staff. This implies that organizations need to keepfocus on the psychological factors affected by organizationalculture when looking to make knowledge sharing moreefficient.
