The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Background: War-related amputations are represented by a unique group of patients because of the wounds complexity and scope of several serious injuries.

Aim: Through the review of scientific articles, this study aimed to identify which oral health-related quality of life instruments that have been used in studies to measure the oral health-related quality of life in older individuals and the application of such instruments.Method: The study is based on a systematic literature review, where 14 articles have been chosen and evaluated against a checklist. Result: The oral health-related quality of life instruments that have been used on individuals, 65 years and older, are OHIP-49, OHIP-14, OHIP-20 or OHIP-EDENT, GOHAI and OIDP. The instruments are used to examine factors associated with the oral health-related quality of life. Significant associations have been identified, among other things, between the number of teeth in static occlusion, dry mouth and the quality of the dentures, and oral health-related quality of life. Social and cultural associations have also been revealed.Conclusions: Today there exist several well functioning instruments that are used for research purposes.

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.

Human capital is professional service firms' most valuable resource and its quality is closely linked to the quality of its services. The purpose of this study is to investigate how professional service firms appraise their employees. A comparative study between an architecture firm and a management consulting firm is conducted with the aim to identify and explain similarities and differences in performance appraisal. Two qualitative case studies are performed and interviews as well as documents are used to explore the area. The thesis builds on a critical perspective and it has an explorative approach.

This thesis which is about working with mathematics teaching has no effect/impact on performance and understanding of pupils. The study is intended to gain insight on working in mathematics education which has an impact on performance and understanding of students who are ethnically Swedish and foreign ethnic. In order to compare the ethnic Swedish and foreign students of ethnic understanding, I judged from their performance on the tests taken in year three. The qualitative approach permeated the work, both interviews and observations which were included in the survey. The qualitative study was chosen to get an understanding of how mathematics teaching is conducted in two different areas.

Denna studie fokuserar på företagsstorleks inverkan på sambandet mellan Corporate Social Responsibility (CSR) och Corporate Financial Performance (CFP). Huvudsyftet är att mäta om effekten av CSR på CFP skiljer sig mellan små och stora företag noterade på Nasdaq OMX Nordic Stockholm. Perioden som studeras är åren 2006-2009 samt år 2011. För att utröna om företagsstorlek har inverkan på sambandet tillämpas modererande regressionsanalys som går ut på att fastställa huruvida någon interaktionseffekt förekommer eller ej. Vi kontrollerar även för variablerna bransch och tid.

Strategies for the board game Hive was implemented and evaluated in this project. The report covers the rules as well as the system that was implemented in order to build strategies. The strategies are evaluated based on how they perform against each other. Two search algorithms were implemented: Minmax and Alpha-Beta Pruning. Alpha-Beta with depth 4 had the best performance against other strategies as well as in individual tests..

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

The global market is becoming increasingly integrated and to keep up with growing competition and to achieve even greater success, companies expand to foreign markets. Previous studies have shown that the concept of psychic distance has an important impact on international performance regarding small and medium-sized enterprises (SME). The aim of our study is to provide the reader with a deeper understanding of how psychic distance influences export performance regarding Swedish SMEs. Through a single case study of a Swedish SME, we chose to research three different markets in three different continents. Our findings show that psychic distance influences export performance through export marketing strategy and active learning.
