AnvÀndbarhet för barn : En kvalitativ studie av SVT Play med fokus pÄ anvÀndbarhet för barn i Äldern 10-12 Är

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

UtvÀrdering av VAV i nybyggt kontorshus

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Undersökning av solcellspotentialen för golfverksamheter i Sverige

Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.

Elevers litterÀra förestÀllningsvÀrldar

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

JÀmförelse av verklig och modellerad elproduktion frÄn en solcellsanlÀggning : En utvÀrdering av tvÄ simuleringsverktyg.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design softwareÂŽs can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The softwareÂŽs used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the softwareÂŽs, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

The purpose of the project is to with a usage-centered design method create a paper prototype of a tool that will help the employees to analyze the log files in a more efficient way than earlier.The result shows how the usage-centered design method was used to create the paper prototype and how the user interface was created according to human-computer interaction (HCI)..

TillÀmpad informationsteknologi i klassrummet

This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.

Kolonisationen har format ma?nga la?nder, men i vilken utstra?ckning? Detta a?r ett aktuellt a?mne eftersom kolonialism fortfarande finns idag. I den ha?r uppsatsen underso?ks da?rfo?r kolonisationens pa?verkan pa? ekonomisk utveckling. Med hja?lp av tva?rsnittsdata och OLS-regressioner visar resultatet att brittiska kolonier i va?rlden, relativt franska kolonier, i genomsnitt haft ho?gre BNP per capita a?r 2000 och att detta tycks bero pa? skillnader i humankapital, demokrati och institutioner.

Jordbruk och mjölkproduktion med kor i Etiopien :

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

Kvalitetskontroll av utskrifter frÄn Kodak Approval XP4

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for ColorcraftÂŽs digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing systemÂŽs natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

Intelligent remuneration in the knowledge economy

Talented people are recognised as being the most important corporate resource over the next twenty years and a competitive compensation system is an important tool in attracting and retaining talent. Traditional pay systems are recognised as being neither cost effective nor motivating people to do more. Often these systems do not contribute to strategic objectives. This study outlines what constitutes an intelligent remuneration system that will enhance the mind value added by knowledge workers, reward knowledge creation, and contribute to organisational strategies..

Modellbaserad systemutveckling i komplexa verksamheter. En fallstudie av Coremetoden

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Uppgradering förarstol SEP: pÄ uppdrag av BAE Systems
HĂ€gglunds AB

En prototyp till en förarstol för det militĂ€ra fordonet SEP har tagits fram av tidigare anstĂ€llda pĂ„ BAE Systems HĂ€gglunds AB i Örnsköldsvik. Stolen mĂ„ste uppfylla en omfattande mĂ€ngd krav dĂ„ den Ă€r tĂ€nkt att anvĂ€ndas i ett stridsfordon, och av personer av varierande storlek. Den nuvarande prototypen för stolen anses dock vara för dyr och det har dessutom framkommit en del klagomĂ„l pĂ„ konstruktionen. Stolen mĂ„ste dĂ€rför göras om sĂ„ den blir bĂ„de billigare och bĂ€ttre. Genom att ta del av tidigare genomförda tester pĂ„ BAE Systems, samt genom att göra nya tester upptĂ€cktes det dels vad som var dĂ„ligt och dĂ€rmed behövde göras om, och dels vad som var bra och kunde tĂ€nkas behĂ„llas.

Marknadsföring av akademiska bibliotek - en jÀmförande studie mellan Sverige och England

This thesis conducts a comparative study between two academiclibraries, one Swedish and one English, in order to analyse ifdifferent funding systems influence the marketing of theirservices. The theoretic foundation is built on relationshipmarketing, which emphasises the importance of creating andmaintaining relationships. A qualitative approach has been usedthrough the use of case studies, with semi-structured interviewsbeing held with library staff and managers in both countries. Inaddition to these interviews strategic plans have also beenanalysed. The result from the study shows that whilst there aresome differences between the two university libraries there arealso similarities, which indicates that it is not clear if differentfunding systems have an impact on the marketing of the services..
