Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Översyn av uppvärmning

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.

Resursrelaterad informationshantering i uthyrningsverksamheter : En studie av verksamhetsstödjande IT-system och identifikationsteknologier

The management of assets in organisations today can be a challenging task and optimising their usage is critical to ensure maximum profit. For rental businesses offering tangible products efficient management of movable assets are an essential part of the business strategy. The main purpose of this study is to investigate how asset management and asset information management can be carried out in rental businesses and in what ways information technology can support it. By doing a literature review combined with a case study where three rental businesses and their use of information technology were examined we could identify several important aspects regarding asset information management. The results we have found is that rental businesses with a high degree of digitization in existing asset information management systems are able to rationalize existing work processes, which in some ways changes the roles of employees.

Tillit i moldavien

Moldova is one of Europe?s poorest countries with a struggling business environment and an unpredictable political situation. The purpose of this thesis is to understand the implications of corruptions and why networks have come to play a key role in the Moldovan culture and if the formations of network are due to heritage or an effect of functionalism. The focus of the study is also to explain how the networks develop and the formation and maintenance of loyalty and trust among the members of the network. The study is of a qualitative nature that uses a key informant sampling method to get access to members of different business networks.

About of 150 students, 50 girls and 56 boys (70%) had experienced bullying of different kinds; some had more than one kind of experience. The students expressed that they had contacted adults when they ?felt unwell? and to ?stop bullying?.

Optimering av prestanda och utnyttjande av flertrådsteknik

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

Projektering av motorvägsbro över Ätran i Ulricehamn - Konceptuell design och preliminär dimensionering

Arkitektkontoret Sweco Architects i Göteborg har tagit fram ett förslag för ett bostadsområde i Varberg, där Varbergs kommun var beställare. De föreslog att ett eget områdesförslag skulle tas fram i Revit Architecture utifrån de planbestämmelser som gäller i området. Som en fördjupning i detta arbete valdes att även studera arbetsprocessen i programmet samt hur denna process kan tidsoptimeras. Ett problem idag är att en sådan process kan vara tidskrävande och ineffektiv. Syftet med detta arbete var att finna idéer på hur processen kan effektiviseras och att utveckla kunskaperna om Revit.Som en inledning modellerades hur området ser ut idag i Revit utifrån en ritning skapad i AutoCAD.

Utvärdering av mikrofon- och högtalarelement för högtalartelefonsapplikation

The project deals with the evaluation and testing of speaker and microphone elements as well as microphone cavity.The first part of the report comprises a comprehensive theoretical part about drivers, microphone elements, and to some extent microphone cavity.The goal was to , on the behalf of the company Limes Audio AB, develop proposals on microphone element and cavity as well as drivers for a speakerphone application, based on specific factors. The main factors were performance, price and form factor.The aim was to create the best possible conditions for Limes Audio's software developers to implement the company's audio-enhancing software, mainly adaptive echo cancellation.The testing was carried out using Adobe Audition and MatLab. The test methods were developed in conjunction with Limes Audio and are described below.The project will result in suggestions for a speaker, a microphone and a cavity. The cavity were removed from the product because the results indicated that the cavity matter little for the end result.The report concludes with a discussion on how the measurements could have been enhanced to simplify the interpretation of the results and making the testing more efficient..

En yteffektiv bostadsmodul

The aim is to design a module for living which is flexible in a bigger context, which could condens the city and to answer the questions: How is it possible to make a livingmodule where the compact living theme works in an everyday situation? How is it possible to make one module which is able to function in several different situations? The process in solving problem has been characterized of trial and error: design a module and learn from the mistakes and take the knowledge to the next module. This is the way I have worked until I found a good solution. As a result I can show an efficient module which has several nice values of space and that is flexible and to some part adjust for a disabled person. It can on several ways condens the city.

Mervärdesskatt för ideella föreningar : Kan allmännyttiga ideella föreningar behålla fortsatt befrielse från skattskyldighet?

The harmonization within EC Company Law has been relativley successful. Despite its relative success; important differences still remains in European company law.The freedom of establishment itself, and the ECJ?s interpretation of the freedom provides European companies with a substantial cross-border mobility. As a consequence of this mobility, together with the differences in national legislation; mandatory rules in company law can be easily evaded. A typical example of this is that a Swedish enterprise, by running their business through a British private limited company, can escape the Swedish legislation on capital contributions when forming a company with limited liability for its members.

The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

Lyckade friskvårdssatsningar : vad är hemligheten?

The increasing health problems in our society have been lifted to the surface and debated for quite some time now. Even though the statistics of bad health somewhat have dropped, the problems still remain. Many companies are wrestling with this and are suffering from huge financial losses due to the costs of people frequently calling in sick for work. This has resulted in an increasingly high expansion of different types of preventive measures in order to avert health problems. But far from all companies reach these goals and it is there for of high value to study how important resources can be used in a more efficient way.The purpose of this study is to achieve a deeper understanding for Health promotive services in companies and to understand which influential factors are crucial in the process of reaching successful strategic Health promotions.

Modelering av Wideband : Code Division Multiple Access

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
