As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

This essay presents a survey that was conducted on 52 college students regarding their opinions on advertisement received to the mobile phone. The questionnaire survey focused on what college students think of advertising to the mobile phone and what attitude they have towards it. The thoughts behind this study are that advertisement to the mobile phones is something that is getting more popular when the mobile phone is getting more advanced. The result of the study showed that college students are not that interested in receiving advertisement to their mobile phones. Several of the college students that participated in the study already get advertisement to their mobile phones, advertisement that they don't want because it doesn't reflect their interests.

The purpose of this study was to describe, understand and analyze the thought behind the perception amongst pedagogues´ on multicultural work in preschools, based on an intercultural perspective. In this study, I questioned the pedagogues´ view on the work in preschools that prepares children for a life in a multicultural society and also the way they describe the cultural challenges.The study was accomplished and questions were answered by studying current literature and previous research in the field. I also interviewed four pedagogues from two different preschools located in separate areas.This study shows that many opinions that pedagogues expressed in the interviews can be traced back to an ?us vs. them? perspective, in which your own culture, the Swedish one in this case, is the most critical and should receive the greatest attention in preschool.

Background: The district nurse's competence description is comprehensive and sets high standards for a wide range of skills. The population's need for health care will rise according to life expectancy, lifestyle diseases and multi-morbidity increases. To graduate as a district nurse, 75 higher education credits are needed and after graduation, the district nurse must have developed both personal qualities and gained skills that makes it possible to work in primary care, child / school health care and home care. Aim: The aim of this study is to highlight the newly qualified district nurse experiences in developing professional identity and describe on how this development affects nursing.Method: In the pilot study a qualitative method with an inductive approach was used, and data collection was made by four semi-structured interviews. The interviews were analyzed using qualitative content analysis.

Introduction Postoperative wound infections leads to increased patient suffering and cost society money because it leads to longer hospital stays. Previous research shows that patient related risk factors such as smoking, diabetes, Chronic Obstructive Pulmonary Disease (COPD), advanced age (>65 years) a low preoperative hemoglobin level (<140g/L) and a high BMI (> 30) increases the risk of suffering a postoperative wound infection. Aim To investigate whether patients that underwent surgery with Coronary artery Bypass Graft (CABG) in a university hospital in central Sweden in 2013 and had any of these risk factors more often suffer from post-operative wound infection.MethodThe study has a descriptive design and is based on an ongoing infection registration area of operations. The study included 148 patients out of 255 (58%) undergoing CABG in 2013. Possible risk factors were collected through medical record review.Results There was no significant correlation between surgical wound infection and patient-related risk factors such as smoking (not quit smoking four weeks before surgery), diabetes, COPD, advanced age (>65 years), low preoperative hemoglobin (<140g/L) or a high BMI (>30) and suffered a postoperative wound infection.Conclusion More research and a larger sample is needed in the field to produce a reliable result could be presented..

This work is based on qualitative interviews with four educationists who before their university studies lack education in their own field of work. The study aims to explore how higher learning influenced and affected these people. As a theoretical point of view the concept of implicit learning and Aristotle?s epistemological approach was used. The study gives an idea that the concept of knowledge is advanced and can go from practical experience to more theoretical understandings.

The aim of this study is to examine Swedish teachers? role and attitude in the Swedish subject towards motivation and reading fiction at upper secondary school. We are also interested in investigating whether or not there are any differences regarding the way teachers motivate students? depending on their choice of education or not. The method we chose in order to achieve this was interviews with teachers.

This essay intervenes in the politics of urban segregation in Stockholm. The main aim of the essay is to analyze and describe how advanced marginality and territorial stigmatization are expressed in the lived experiences of four unemployed youths, that have participated in a labor market training program located in the ?social vulnerable? area Rågsved. With a theoretical framework based in Henri Lefebvre?s production of social space the empirical findings are interpreted in regard to how the youths produce social space in dialectical interplay with urban politics, advanced marginality, territorial stigmatization, and their local neighborhood.

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

Syftet med denna studie är att utreda begreppen big data och analytics. Utifrån vetenskapliga teorier om begreppen undersöks hur konsultföretag uppfattar och använder sig av big data och analytics. För att skapa en nyanserad bild har även en organisation inom vården undersökts för att få kunskap om hur de kan dra nytta av big data och analytics. Ett antal viktiga svårigheter och framgångsfaktorer kopplade till båda begreppen presenteras. De svårigheterna kopplas sedan ihop med en framgångsfaktor som anses kunna bidra till att lösa det problemet.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

This study indicates that research about men and masculinity does not appear to have advanced as far as research about women and femininity. Similarly to attitudes concerning women and femininity, clear norms and attitudes regarding men and masculinity pervade society. Hence, there is a clear need for further research within this field to be carried out. This study, with the support of previous research, looks at gender norms which exist in educational material and the impact it might have on students. Against this backdrop, the author has focused the analysis on one textbook as educational material at upper secondary level with particular emphasis on masculinity and its associated norms.
