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.

Med snuset i fickan: en beskrivande och analyserande studie av snusande ur ett sociologiskt perspektiv

The aim of this essay was to describe and analyse the use of snuff as a social activity. By accomplishing eight qualitative interviews with snuff-users I wanted to get a glimpse into their relationship to the snuff and find out in which situations and frames of mind the snuff-use alter. I also wanted to find out if age, class or gender has any affect in snuff-using. The interviews were analysed in a sociological perspective with help from Erving Goffmans and Joseph Gusfields ideas, among others. I found out that each snuff-user creates his own rituals and routines, but there are factors in daily life, which can change the use of snuff.

Restinformation i elektroniska textdokument

Some word processing programs save information that not all users of the program are aware of. This information consists of a number of things. Example of that is who the writer of the document is, the time it took to write it and where on the computer the document is saved. Text that has been changed or removedcan also be saved. This information is not shown in the program and the user will therefore not be aware of its existence.

Läsförståelse eller litterära föreställningsvärldar : Litteraturpedagogisk diskurs inom gymnasieämnet engelska

Reading and analyzing literature has a long tradition of being an essential part of the teaching of English in Sweden. As the offers of entertainment have increased in popular culture with the introduction of computer games, internet and other media, interest in reading novels has decreased. Literature is still a compulsory part of English teaching and the question is how teachers of today use literature and what kind of literary instruction they use.The aim of this study is to explore and discuss the literary instruction discourse in pedagogical texts, lessons, created by and for English teachers of Swedish Upper Secondary Schools. The lessons have been collected from the site lektion.se, where teachers are able to share knowledge and lessons. The study uses an analytical method based on Norman Fairclough´s Critical Discourse Analysis in order to analyze the lessons.

Utveckling av ögonstyrt kommunikationshjälpmedel för intensivvårdspatienter

Thousands of people all over the world suffer from injuries that temporary affects their ability to speak or inother ways communicate. A very common procedure for persons that suffer from some kind of breathingproblem in the higher parts of the neck is called tracheotomy. This prevents the patient from speaking whenno air passes the vocal cords. There have been many studies done to understand how these patientsexperience this period. The results are consistent, the patients often feel fear, frustration and worries aboutthe future.Tobii Technology develops a technique called eyetracking wich enables persons to control a computer with theeyes.

Inredningskoncept för vägambulans : Ett examensarbete vid Industridesignprogrammet 2011

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

Upplevelsen av hopp vid olika tillstånd av ohälsa : En litteraturöversikt

Om eller när en person drabbas av ohälsa, orsakad av exempelvis sjukdom eller olyckshändelse kan känslan av hopp vara en styrka som bidrar till att klara av situationer som kan upplevas svåra eller krävande. Hopp beskrivs som ett mångdimensionellt begrepp och kan vara en nödvändig del i anpassningen till en ny situation. Transition innefattar processen i en förändring hos människor som av olika anledningar drabbas av ohälsa, där hoppet är en väsentlig del. Hopp kan upplevas på olika sätt, därför finns det ett värde om vårdpersonal kan ge personcentrerad omvårdnad, en individuellt utformad vård. Litteraturöversiktens syfte är att beskriva personers upplevelser av hopp vid olika tillstånd av ohälsa.

Att vårdas på sjukhus : Patienters upplevelser av vårdmiljön på sjukhus

Bakgrund: Vårdmiljön på sjukhus har traditionellt utformats av arkitekter. Fokus på patienten har skiftat från subjekt till objekt, för att åter gå mot en syn som subjekt. Intresset för utformning av vårdmiljön har de senaste åren ökat. Problem: Patienterna inneliggande på sjukhus befinner sig i en utsatt situation. Sjuksköterskor på sjukhus har lite kunskap om hur vårdmiljön påverkar patienterna vilket behövs för att kunna arbeta efter ett personcentrerat perspektiv.

Textila cylindrar - experiment kring solljusreglering

Working with a three-dimensional shape that adjusts light seemed exciting. Venetian blinds became a basis and source of inspiration in my project. What is a Venetian blind? I arrived at the de?nition ?a surface of angleble pieces for sun adjustment?. From that simpli?ed meaning I started making sketches of what an alternative model could look like.

Doktorander och e-böcker ? en användarundersökning

The purpose of this thesis is to study the usage of and attitudes towards electronic books among graduate and PhD students at Karlstad University. The main questions are: How do graduate and PhD students use electronic books? To what extent are electronic books used compared to printed books? To find the answers, a user study was carried out at Karlstad University library. The results show that a majority of the respondents are aware of the possibility to use electronic books but prefer to use printed ones if they have to choose. Many respondents also complained about difficulties reading a text on the computer screen.

Förebyggande Brounderhåll

AbstractThe Swedish Road Administration in the region of Mälardalen has since 2004 worked to in¬crease the efficiency of the maintance of bridges based on limited functional requirements and time demanded action.The maintenance of the bridges is contracted in the county of Uppsala since 2004, and Örebro since 2007. The county of Nyköping and Västerås is contracted by the traditional system. The contractor will perform a regular maintenance on all bridges. The bridges are inspected by the contractor at least once every year.The contractor registers the result of the inspection in a database called BaTMan. BaTMan is a Bridge and Tunnel Management system and is a strictly web solution were the user logs in via the internet.The Swedish Road Administration also inspects the bridges to se that the demands on the bridges are followed.My work is to compare these different inspections and to see any development..

"TILL SYVENDE OCH SIST ÄR DET VI SOM BESTÄMMER" En undersökning av folkbibliotekariers syn på användare på fyra filmavdelningar

The aim of this master´s thesis is to examine how librarian´s views of the users can vary for different types of materials in public libraries. We have seen that literature and reading are the central parts of the libraries in Sweden. All other types of media are traditionally seen as complements and in focus for the study is feature film as an example of these other medias. We examine policy documents to see the official view of the general target group of the libraries and compare it to the view of the users of feature films as expressed by the librarians. The study includes several different types of empirical materials such as interviews, observations and documents and the method used is case studies.

Den viktiga historien : Historiesyn och historiemedvetande i studentexamensuppsatser från åren 1877 och 1929.

The purpose of this thesis is to identify and analyse the view and consciousness of history present in essays written by Swedish high school students in 1877 and 1929. A theoretical framework was established in order to accomplish this, based on the theories of Peter Aronsson and Jörn Rüsen (through Lars Andersson Hult) that defines consciousness of history through a matrix that expresses a progression as well as a scaling complexity. Furthermore, the theories of Knut Kjelstadli and Magnus Hermansson Adler were adopted to establish two different types of view of history: one adhering to a view of history where groups and individuals are seen as integral to the progression of history, and the other explains historical process through more functional explanations, such as dependant on cultural and social structures.This framework erects ideal-types of different types of view and consciousness of history, and the thesis at hand strives to categorise the different kinds of view and consciousness of history found in the studied essays in accordance with these ideal-types through two different models based on the above mentioned theories.The findings presented here largely point to a view of history that is largely centered on an actor-oriented view of history, where individuals such as kings and generals are given a central position when historical events are being narrated, and is present in both 1877 and 1929, with some shifting nuances. As for the consciousness of history the lion part of the analysed texts can be seen adhering to a more traditional type of consciousness in 1877, although a slight shift can be seen towards a more complex type of consciousness in the texts from 1929..

När det inte blev som planerat : Patienters delaktighet i det infektionsförebyggande arbetet och i upptäckten av tidig postoperativ infektion vid höft- eller knäprotesoperation

Höft- och knäprotesoperationer är idag en vanlig operation vid artros i höft- och knäled. Trotsminutiösa infektionsförebyggande förberedelser inför operationen drabbas ändå en delpatienter av postoperativa infektioner. Vid ortopedisk proteskirurgi är postoperativainfektioner ett direkt hot mot den nya inopererade leden och kan leda till långabehandlingstider som påverkar patientens livskvalitet under lång tid.Syftet med studien var att utforska patienters möjlighet till delaktighet i tidig upptäckt avpostoperativ infektion utifrån given information vid operation för höft- eller knäprotes.Semi-strukturerade intervjuer genomfördes med tio patienter med diagnostiserad postoperativinfektion efter höft- eller knäprotesoperation. Transkriberade intervjuer analyserades medinnehållsanalys. Journaler granskades för att beskriva patientens tidigare sjukdomar.Resultatet visade att första tecknen på infektion kan beskrivas med temat: Vad är normalt ochvad är inte normalt.
