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.
Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material
With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
Funktionskontroll av stegljudsisolering vid konstnärligt campus i Umeå
This report's aim is that by field measurements determine the function of Aprobo soundproofing material dB2 for reducing impact sounds, the measurements is done in ?the school for fine art? in Umeå also known as ?konstnärligt campus building nine?. The construction technique is used in areas sensitive to impact sound between different floors in the building. The measurement?s is also to do a function control of the buildings sound quality compared to Swedish and European standard when it comes to air sound, impact sound and reverberation time .
Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Riskhanteringen ingår i kulturen : En kvalitativ studie av riskhantering i en ideell idrottsförening
Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.

Kundanpassad LCA för nätverkskameror
Antalet övervakningskameror i samhället ökar, samtidigt som deras miljöpåverkan är relativt okänd. För en produkt som tidigare bara utvärderats gällande prestanda, börjar kunderna nu efterfråga en kartläggning av miljöpåverkan. Kamerans miljöpåverkan studeras ur ett livscykelperspektiv: energi- och materialtillförsel samt utsläpp och avfall som berör allt ifrån råmaterialutvinning till slutåtervinning. Projektet är genomfört på begäran av, och för, Axis Communications AB (härmed refererade till som Axis) med huvudsyfte att öka Axis kunskap om deras produkters miljöpåverkan och utveckla en metod för genomförande av förenklade livscykelanalyser på Axis produkter. Livscykelanalysen, LCA, genomförs på en nätverkskamera utvecklad av Axis Communications AB; modell AXIS Q6032-E PTZ.

Bland mumier och mosslik - en jämförande studie av populärarkeologi och fackarkeologi
In my paper I have compared popular science and neutral science regarding language and construction. My task was to find out if there are differences between the language of popular science and that of scientific science. The purpose of my paper is to answer four questions1.How do the authors present the bogbodies and the mummies in the two categories?2.What does the popular science imagine that you want to read about?3.Is there a difference between the target groups of the two categories?4. Does the presentation of the subject have consequenses when it comes to contents and readers?I have studied how often the authors use drawings, photos, diagrams, maps, and if the titles of the chapters can tell you something about the nature of books.

Makt i klassrummet : En maktanalys av relationen mellan lärare och elev
This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.
