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.

AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.

Background: The majority of patients requiring medical attention experience some degree of pain. The nurses´ assessment of pain is crucial in reducing the patients suffering in a proper and timely manner. Previous studies have shown that the treatment of pain in a emergency situation is poorly managed. The patients´ pain experience is often under assessed and undertreated which leads to increased suffering for the patient. This results in higher costs for the health care system due to prolonged hospitalization.

AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.

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.

In this study ? Just a girlfriend who lives far away? ? I interview fifteen girls about their experiences with computer mediated relationships. From a queer theoretical perspective I examine how these girls do and talk about their relationships, in relation to norms about relationships and sexuality as well as notions about online and offline.My aim is to discuss in which ways the performing of these relationships both reproduce and challenge norms about relationships and sexuality. The girls I interview attempt in different ways to show that doing relationships online is just as ?normal? as doing them offline.

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..

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.

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.

Information and communication technologies (ICT) are constantly evolving in today's information society. The school uses ICT as a teaching tool and it begins to be included at the leisure-time in school by the educators.Aim of this study is to examine how educators describe their perceptions and experiences of using ICT in the leisure activities. The questions is about how the educators use ICT, what they believe children learn of ICT, and which advantages and disadvantages they see with ICT at leisure-time in school.Through a qualitative approach, I have had my questions answered by six trained educators, five of whom are recreational educators and one who is a preschool teacher. These have individually answered my interview questions as an interview took place over a phone call, while the others answered the same questions by e-mail. The interview questions were open-ended questions that were formulated so the educators could respond so freely and fulfilling as possible.The survey shows that teachers use ICT in multimodal approach at leisure-time in school, both in informing parents and in activities with the children.

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.

This paper examines which media messages related to happiness that can be found in interviews with famous people in the four largest lifestyle magazines in Sweden for the age group 16-34. The magazines are Cosmopolitan, Elle, Café and King. Depending on which magazine the reader chooses to read he/she will be presented with different roads to happiness. Common for all examined magazines are happiness factors related to personal goals, determination and work. Often in a causal connection where the goal orientation and determination is tied together with success in work and career for the interview persons.

Small business enterprises have escalated in Sweden during the last decade. However, new established companies are struggling to maintain their selves during the startup process and according to a survey from Tillväxtanalys, only 68 % of startup companies from 2008 were still active three years later. One of the main reasons is lack of capital and the most common approach to finance companies is to apply for a bank loan. In other words, commercial banks are of great importance for new businesses. Although, the problem arises when there is no previous history from the new businesses that the bank could base its credit assessment on.

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.

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.
