Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Att indexera hållbarhet : En metautvärdering av Miljöaktuellts rankning av svenska kommuners hållbarhetsarbete

This Bachelor's thesis in Environmental Science studies the quality of an index of performance measurement of Swedish municipalities' sustainability governance offered by the environmental magazine Miljöaktuellt. Executed for six consecutive years, this evaluation is arguably the most comprehensive and widely spread local sustainability assessment in Sweden. Contextualizing this quantitative measurement tool in the paradigm of New Public Management, the research questions posed are: 'to what extent does the index employed by Miljöaktuellt correspond to the requirements of a set of quality criteria for sustainability assessment?' and 'is the index appropriate as a measure of, or a goal for, Swedish municipalities' internal sustainability efforts?' Through the perspective of evaluation theory, Miljöaktuellt's index is seen as a performance evaluation, thus categorizing this study as a meta-evaluation. Through a qualitative thematic approach, the index is analyzed using the 8 BellagioSTAMP-principles that were developed as tools for assessing quality of sustainability assessments as themes for the analysis.

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.

Socialtjänstens roll i arbetet med brottsoffer : En studie ur socialsekreterares perspektiv

The purpose of this essay is to explore the social services work with crime victims in Sweden, according to Chapter 5, § 11 of the Social Services Act. The study examined how social workers define the victim and assessing and prioritizing victims' needs. It has also been central to study how social workers interpret and understand the regulation of social services responsible for crime victims.Qualitative interviews with 18 social workers is the basis for the study. The analysis of the social services work with victims based in the above-mentioned interviews. The interviews analyzed using the sociology of law theory.

"Sanningens ögonblick" : En uppsats om organisationsprinciper och deras betydelse för kundorienteringen hos folkbibliotek

In writing this study, I wanted to examine which principles of organization that are possible for Swedish public libraries to use, and what these principles mean for the libraries customerorientation. This is done by examining a number of written sources, as well as studying the organization of six public libraries. I found several possible principles, but a number of principles have been more commonly used than others. Historically most public libraries were organized according to the functions needed to be carried out within the organization, but today it is much more common to use subject-based organizations, with some examples of organizing according to user-groups and needs. I have also encountered the possibility of organizing according to the sources that are to be handled, or the way in which these sources are used by the customers.

Det är lite gambling, man kan aldrig veta hur det blir i slutändan : Socialsekreterares erfarenhet av bedömning av en viss insats för barn och ungdomar

Social workers in this study describes various experiences of the assessments of interventions for children and adolescents. Social workers experience of the many different situations where an assessment of best effort must be made on the basis of BBIC, which is the Social Services investigation records. To make this assessment, the Social workers need social assistance and support of their colleagues and manager. Knowledge mixed with experience is also an important part when it comes to being professional and not let emotions control that could otherwise be happened when the social worker meets and builds relationships with clients. Social workers are also those who will decide which achievement the client needs from the needs.

Implementering av ARINC429 testutrustning med 16 kanals kommunikationskort och dataSIMS

This bachelor thesis includes two different manuals and design of an interface box between a test object and a general test station (computer) with ARINC429 communication.There are three different purposes with this project:The first is to setup a general test station with ARINC429 communication using a communications card from DDC (DD-42916i3-300) and software from Ampol Technologies (dataSIMS).The second is to design a new interface between the test computer and the test object. As well as implementing two components in the equipment.The third is to write two separate manuals to guide the users of this equipment. There are two different kinds of users of this equipment, technicians and system engineers. Technicians use the equipment to test and repair flight components. System engineers will implement new components in the equipment.The result of this project is a working test station with a new interface and two manuals..

Stereotyper i den virtuella världen. Hur visuella intryck påverkar deltagares uppfattningar av virtuella agenter

The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..

Intranät En kommunikationskanal för alla?

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

Grundskoleelevers samlärande och undervisningen i informationssökning

Education in information seeking is often traditional and focused on technology. When it comes to this sort of education, research proves it is unusual to pay attention to the interaction between students. My intention has been to examine if it is possible to pay attention to the interaction between students, in order to create more and better situations of learning. The issues in this work are about describing the students? interaction.

Att datorisera ett bibliotek: datoriseringen av skolbiblioteket på Sunnerbogymnasiet i Ljungby

The purpose of this paper is to describe methods to computerize a library and to compare theory with a process in a school library. The case study is based on a school library called Sunnerbogymnasiet which is situated in Ljungby. My questions are;- Which methods are parts of the process to computerize a library?- Which methods are used in the process in Sunnerbogymnasiet?- What does the practical process look like compared to the methods described in theory?In the paper I present the methods in the process according to the studied literature and compare these with a process at Sunnerbogymnasiet. The most significant result is that cooperation between the school library and the community library was the most important reason for the choice of library computer system.

Villa Furulid : gamla anor möter dagens behov

The last years? financial situation has contributed to an increased willingness from the banks to handle risks. The most important risk to cope with is a risk that is related to a customer?s ability to repay loans. Forecasts indicate that in the future, Swedish farmers will be facing profitability challenges, which points to a need to reconsider the banks procedures considering risk management in credit granting for agricultural businesses.Today?s risk management will be given two complements in this study.

Från disk till rum : Basel II-effekter på kreditrisk och information

This study examines the effects of credit risk and information disclosure in the new bank regulating system Basel II on bank and bank customer. The effects are then discussed in a perspective of the economic man and information asymmetric theories. Furthermore is the Basel II effects on the capital adequacy of Andelsbanken för Åland examined.The approach of the study is qualitative and several interviews with individuals on different levels of the examined bank, Andelsbanken för Åland, have been carried out during the collecting of empirical facts about the effects of the regulating change from the Basel I system to Basel II.The research findings are as follows:Andelsbanken för Åland have increased its capital adequacy ratio from 12,7 percent to 14,4 percent, mostly due to lower risk weights on housing mortgages compared to Basel I. Andelsbanken för Åland have started to use a completely new credit risk and customer assessment system which classifies every customer and gives them a credit rating. The system cause a much heavier information gathering of the customers profile as well as a much better assessment of risk than the previous system, which the bank finds positive.
