Iterera, iterera, iterera : En studie om hur en upprepande designprocess kan förbättra användbarheten i Provbankens interaktiva distansprov

Provbanken är en del i ett nationellt provsystem som är tänkt att vara ett bedömningskomplement till existerande prov i gymnasieutbildningen. Växjö universitet har varit delaktig i utvecklingen av prov för de yrkesinriktade ämnena sedan 1997. Eftersom innehållet i dessa numera webbanpassade prov är det väsentliga, måste utformningen av provet göras lättförståelig. Användbarheten måste m a o vara självklar och inte ställa till problem för användaren. Som en av utvecklarna av dessa interaktiva prov, ville jag finna ett sätt att minimera problemen och öka användbarheten.

Automobike: en cykel med aktiv balans

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

CAP KC3-12 : Design and finite element analysis

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

Har en goodwillnedskrivning någon effekt på aktieavkastningen? : En eventstudie av bolagen på Stockholmsbörsen

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.

DFM för Lasersvetsning

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.
