Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.

In this paper we have examined why seniors do not use e-business to the same extent as other age groups. Seniors belong to the age group that, according to statistics from Statistics Sweden (SCB) in 2011, utilizes e-business the least in relation to the number who use the internet. To understand how seniors reason and perceive the possibility to shop on the internet, we have conducted four interviews with people from 65 years and older. We have let the respondents answer questions regarding utility aspects, e-business interfaces, general shopping habits, risks, and whether or not they usually shop online. We also found out how seniors reason when they sell products and services.

This report presents the results of the tests of data rate and signal strength that I have conducted. The tests have been performed in the municipality of Arvidsjaur, Sweden. The report also contains the conclusions I have drawn from the results as well as an introduction to radio and the technology used in the nets that have been testedThe equipment used is:LG G2 cellphone used to test Telias 3GHuawei b593s-22 3G/4G router used to test Tele2s 3G/4GMobile Broadband Gateway R-90 used to test Net1s CDMAThe data rate has been tested with bredbandskollen (www.bredbandskollen.se). The signal strength(RSSI) has been read in the configuration menu of the broadband routers as well as in the cellphone.The conclussions drawn:Net1s net appears to be more used compared to its capacity than the other netsTele2s net has a high and even data rate where it?s signal strength is sufficient.

In my study, I have chosen to examine how the user interface and content must conform to design guidelines for responsive design makes it suitable for diverse desktop environment and for varied mobile platforms. The purpose of this study is to examine the extent recommended design guidelines based on scientific research has a positive impact on user performance and perception when using this study delivered hi-fi prototype. The goal of this study is to provide a Hi-Fi prototype with high usability that will introduce and inform the public about BrasilCine according specifications. Study findings from user testing and supplementary questionnaires show that the implemented technologies as design guidelines for responsive design and design features have a positive impact on user performance and perception. The study results are therefore relevant for further prototype development..

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Anva?ndandet av internet i mobiltelefonen har o?kat drastiskt de senaste a?ren och detta fenomen inneba?r att ma?nniskor har tillga?ng till internet i sto?rre utstra?ckning a?n fo?rut. De svenska bankerna har tagit tillvara pa? denna trend genom att utveckla mobila bankapplikationer da?r de erbjuder sina kunder mo?jligheten att utfo?ra banka?renden med hja?lp av mobiltelefonen. A?ven om fo?rdelarna med denna tillga?ng a?r ma?nga, finns det a?nda? vissa nackdelar.

During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.

The objective of this study has been to examine which significant values are of importance in the telecom sector today, and in a continuing perspective yet to be. To ensure the factors of relevance in the study, we have identified three purposes: - Our first purpose is to clarify the eminent values in the competitive market of the mobile phone operators today, and the reason for its importance.- The second purpose is to understand the function of the brand regarding to value creation and loyalty in the sector of mobile phone operators.- The third purpose is to explore the potential approaches for mobile phone operators to increase value.In this study, our approach has been a qualitative methodology by conducting seven interviews with respondents related to the telecommunication sector.As a result of the process, we find the need to divide the concept of value into two dimensions, which we entitle organizational related values and customer related values. We have found the values related to the characteristics of the market in aspects of its infrastructural features but also in regards to the homogenous core service.Our findings in the empirical data with support to our theoretical frame of reference, is the current highly important organizational related value of constant high result quality (well-functional technological aspect), and the value enhancer by a low price; the strategy of bundling also results in higher value. This result in customer related values that perceives as safeness, availableness and convenience. The brands are a significant source of customer related values with identity value, image value and assuredness. A continued advancement in process quality and individualization will imply greater customer related values of closeness, freedom and flexibility. .
