A recent trend in the technological evolution has been to increase the mobility of the end-user. A contributing factor is the fast rate of improvement in the smartphone area. This, in turn, has changed the expectations end-users have on the availability of services, which has allowed mobile applications, apps, to find their place in everyday life.This study has been conducted at Scania?s Fleet Management department that offers a web-based service where haulage contractors can administer, monitor and follow up on their vehicle fleets. The purpose of this study was to investigate if Scania?s existing web service should be extended into the mobile area, and if so, what organizational and technical challenges app development imposes.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

In this bachelor thesis we have studied how interaction designers describe their profession. The research material is based on nine interviews with interaction designers. Questions cover areas such as interaction design tasks, what abilities they consider important, how they describe their relationship to the users, and cooperation with colleagues. We have analyzed the results using key terms such as habitus, field, and capital, as described by sociologist Pierre Bourdieu. The interviewees express humanistic views, and ask for more cooperation between interaction designers, as well as other people within the field of IT production.

This paper analyses the potential extent of labour mobility in the European Union after the eastern enlargement that took place in 2004, but focuses on movements from the 10 new member countries to the old EU -members. In this study, a number of economic models are used to investigate if there is a large potential for labour mobility in the enlarged EU and also if this potential has large effects on mobility in reality. The potential for labour mobility is, to a large extent, discussed in terms of theoretical migrating incitements for workers and different types of labour migration obstacles. Many factors indicate that such large potential for migration actually exists, mainly due to high difference in wages and unemployment and because of the common EU market. At the same time, the presence of natural and constructed obstacles is likely to restrict migration for a long period of time..

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

This paper researches how the palimpsest concept is used in relation to landscape, and how it can function as a tool within landscape architecture. Palimpsest originally refers to old parchment handwritings, where new text has been applied on top of effaced, but still discernable, earlier writing. Superimposition of information is the core of the palimpsest concept, used within a range of scientific as well as cultural fields. The purpose of this paper is to find how a landscape palimpsest can be distinguished among the many different layers of landscape, such as historical or cultural, and to examine the potential use of the concept in theory and practice of the landscape architecture field. The study is conducted as a literature survey, examining the use of the palimpsest concept within academic works related to landscape.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

The purpose of this study is to investigate which types of cultural capital gives high status in the current field of ?the creative industry? ? a group which could be seen as a new power elite in Gothenburg ? and how people with the ?right? cultural capital is included in the field. The author is invited to several free events within this field, and is investigating the process of inclusion with an auto-ethnographic method. The study will show that the process of inclusion is working quite absolute in the field of the creative industry, and that the audiences are mainly homogenous: masculine, white, middle class, has a taste disposition of the ?eclectic omnivore?, has entrepreneurial knowledges and is an active social media agent.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

Målet med denna undersökning är att teoretiskt undersöka den vatten/litiumbromidbaserade absorptionsprocessens potential ombord fartyg då processen enbart drivs av huvudmaskinens högtemperaturkylvatten. Undersökningen genomförs teoretiskt mot tre olika fartyg samt Sjöfartshögskolan i Kalmars maskinrumssimulator. För vardera fartyg undersöks driftenergikällan och kylbehovet ombord. Med det som underlag dras en slutsats om den vatten/ litiumbromidbaserade absorptionsprocessens potential ombord fartyget. Fartygens resultat ligger till grund för slutsatsen.

The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

 Through teaching, pupils are given the opportunity based on their personal experiences and current events to express and consider their views in relation to others who hold different views. As a result, pupils should be encouraged to get involved and participate in an open exchange of views on societal issues (Skolverket, 2011d, s. 189). To assess pupils orally in the subject of civics in primary education is an unexplored field, which makes this field relevant to explore. There are numerous researchers? who with the help of deliberative methods, formative feedback, formative assessment and studies regarding classroom climates whom all speak positive about using discussion/dialogue in education to upraise and develop learning among pupils.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

The aim of this undergraduate thesis was to formulate advices regarding the use of field beans, cultivated together with spring wheat, as whole-crop silage in feeding to dairy cows. In the thesis, optimal harvest time of the field bean/spring wheat crop, as well as the feeding value and the fermentation quality, was studied. On the research station at Röbäcksdalen in Umeå field bean/spring wheat (70 % respective 30 % of normal seed rate for the pure crop) and pea/oat (70/30) was grown in field experiments both 2002 and 2003. The following year, 2004, the pea/oat crop was excluded and instead field bean and spring wheat was cultivated in three different mixed ratios (field bean/spring wheat; 100:0, 70:30, 30:70). Every year the crops were harvested at four different development stages and the green forages were used in ensiling experiments.
