Pedalkraft system : Stödsystem för elproduktion i småskalighet

Detta examensarbete vänder sig till personer som är intresserade att använda nya miljövänligametoderna för elproduktion eller personer som redan använder små vindkraftverk ochsolpaneler med behovet av en extra energikälla i små stugor eller avlägsna platser där tillgångentill elnät är omöjligt. Syften i detta arbete är först och främst att bygga ett system förelproduktion med hjälp av en cykel. Sedan bestämma mängden av elektrisk energi en personkan alstra med systemet. Slutligen svara om detta system skulle kunna använda som ettstödsystem för elproduktion i småskalighet.Den första målsättningen är att utforma ett system med användning av kraftelektronik där denkraften som genereras matar lasterna. Den mekaniska delen kommer att konstrueras som en delav energikällan, därefter kommer det att utformas en kontroll för att styra effekten viaelektroniska komponenter, de elektriska belastningarna matas av systemet, kommer attsimuleras.

Utökning av mätområdet för turbinverkningsgraden på avgasturbo

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

The impact of the EU Timber Regulation on the Bosnia and Herzegovinian export of processed wood

Illegal logging and its related trade is of great concern around the world. The European Union Timber Regulation (EUTR) is a regulatory approach by the EU to prevent illegal timber and timber products to be placed on the European Union inner market. This means the regulation affects both actors in the member countries as well as the actors exporting timber and timber products to the EU from non EU member countries. This study aims to study the implementation process of the EUTR in Bosnia and Herzegovina (B-H), and its preconditions. Institutional theory is used to understand and explain how the EUTR affects B-H organisations? business environment, and how the organisations choose to respond to the EUTR.

Stöpt i kulspruteolja en litteratursociologisk studie av den unglitterära tidskriften 40-tal och dess idéklimat.

This masters thesis is a study of the ideas brought forward in the literary magazine 40-tal. The methodology involves the adaptation of a literary sociological perspective where the ideas of the young literary avantgarde in the magazine 40-tal interplays with the established philosophy of the Swedish society during the period 1944-47. The main purpose has been to examine 40-tal as a product of supreme individuality that originates a unique climate of ideas which exceeds the involved collaborators individual writings. I have thereby related my analysis to the Marxist oriented theories of Raymond Williams. This has been done in order to see how the external pressure of the social structure and the market acts together with the internal pressure of keeping up with the times and how this affects the individual authors and the process of creating.

Energioptimering av industriellt tryckluftssystem

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

Värmesystemsutveckling

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

Den rättvisa skatten - Ett etiskt argument för platt skatt

How should a fair income tax system be designed? Since Estonia became the first country to introduce a flat tax on incomes in 1994, this question has been in focus of public debate. The aim of is this thesis is to show that a flat income tax system, combining a proportional tax rate on all incomes with an allowance exempt from tax, is consistent with the demands of justice. In order to achieve this I construct a two level argument using normative method. The first part consists in the justification of a specific ethical theory which is derived from to notion of human dignity.

Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Högtrycket-Initierande undersökning av nytt limträmaterial

The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..

Komponentbaserade ramverk : vilka faktorerpåverkar företag vid valet av ramverk?

An information system is something that evolves over time to enhance the company that is using it. The technology for building an information system is also evolving. New methods and new programming languages make system development easier. As new technology breaks ground and the demands of a company?s information system grow, the company will sooner or later get to a point where a change in the base of the system is necessary.

Intern marknadsförings inverkan på extern marknadsföring

Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.
