Masshantering av schaktmassor : en jämförelse mellan traditionell masshantering och GPS-styrd masshantering i realtid
The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.
Identifiering av synkronmaskinsmodell genom SSFR-test
At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The
goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties
of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP.
The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in
buildings..
Framställningar av tiggare & tiggeri. : En kvalitativ text- och innehållsanalys av debattartiklar i Dagens Nyheters mellan 3 september 2010 och 24 februari 2014.
The aim with this study was to analyze and understand how begging is constructed as a social problem in Sweden between September of 2010 and the end of February in 2014 in debate articles in Dagens Nyheter. To do this I have chosen to use a social problems theory and critical discourse analysis to highlight some aspects in the process of defining the social problem. The study's main finding is that the construction of beggars and begging appears to be in a relatively extensive redefinition in the current situation. It is shown by, for example, a shift in focus in the discourse. For this reason, it is relevant for social work to examine how the construction progresses..
Kan man tala om en norm utan att befästa den? : En diskursanalys i hur homosexualitet behandlas i läromedel riktade till skolans senare år.
The purpose of this essay has been to investigate the research and national initiatives regarding film and Cineliteracy in the Swedish curriculum.The results show that, after all research, national initiatives and the continual clarification from the Swedish National Agency for Education concerning film's place in the Swedish subject, the vision of students cineliteracy not at all obtain an obvious place in the curriculum.The research points out the main causes behind this result to be teachers' lack of expertise and the fact that the formal education for future teachers in the subject still upholds traditional views on the subject of Swedish.The initiative presented in this essay also show lack of continuity, lack of adequate professional development opportunities for teachers and lack of practical guidance manuals to help teachers to develop and educate their pupils in line with current research and visions. .
Bön och upplåtenhet : En religionsfenomenologisk undersökning
Religious phenomena, such as prayer, have more or less always interested and engaged people, but most likely for different purposes. Since the early 20th century, starting notably with Edmund Husserl and especially Martin Heidegger, phenomenologists have taken an interest in understanding and expounding the meaning of religious phenomena. The attention of such a discourse have not ceased but is rather current, and also of importance seeing that religious themes, such as prayer, still occupy a great extent of human life and practice.Phenomenology of religion is not a science of religion: the former approaches religion in terms of its meaningfulness, whereas the latter as an object of inquiry and in the same manner as an economist approaches economical indicators in order to understand and explain how the whole economy functions. In other words, phenomenology of religion expounds religion, as it were, from within, while science of religion does it from without or externally.When approaching prayer phenomenologically, it shows itself to be a process or structure through which the one praying empty himself in order to be able to receive the valuable presence of the other. The value that is received from the other will also be reflected by the one praying and in that sense effect his surroundings and fellow humans..
"Man Kan Inte Klappa Med En Hand" : En intervjustudie om pedagogers uppfattningar av invandrarföräldrars delaktighet i förskola
The purpose of the study is to explore preschool teachers experiences of how immigrant parents become involved in the preschool activities and how their linguistic and cultural background appears in relation to participation.The survey was conducted through individual interviews with eight preschool teachers working in various multicultural preeschools.The results of this survey shows that the preschool teachers perceive that parents with different cultural and linguistic backgrounds are reluctant to participate in various forms of cooperation, such as parent meetings. Preschool teachers believe that the lack of parental participation depends on the parents linguistic and cultural backgrounds, such as different approaches to understand the pre-school educational activity or the view of parenting, and other things such as language difficulties.Another result reveals also a great lack of written methods, because teachers sometimes face difficult dilemmas. To seek itself the right approach in a current situation can be both difficult and time consuming, therefore, the preschool teachers wish that there were already complete methods for use..
Jag trivs bäst när havet svallar, och måsarna ger skri : En textanalytisk studie av biologisk mångfald i läroböcker
Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems.This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years.In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers.The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity..
Ekonomin i syrning av spannmål till mjölkkor :
In this dissertation I have tried to figure out if it possible to make any money on acid grain to feed cows through a case study. The method is a case study combined with a documentary research. At present the farm sell all grain in connection with harvest and buy it back continuously in the neighbourhood, I have compared that with an alternative where I invest in a construction for to store acid grain on the current farm.
I have delimit me to only have a look on acid grain because I think that is one of the cheapest way too store grain in smaller aplenty. Before beginning with acid grain is it important to be versed in how everything works and the risk to keep on with acid grain.
One disadvantage is that the acid grain is not possible to store more than 12 months with out acid it once again. It is also easy to get mould in the pasture if it is not acid enough.
Litteraturrecensioner i Expressen och BLM 1964-2004 : En studie av genreförändringar i två skilda pressorgan
The aim of this study is to describe how reviews of literature in Bonniers litterära magasin and Expressen changed during the period 1964-2004. The investigation is based on 20 reviews of novels and short stories, which are analysed with a method described in Hellspong and Ledin (1997) and inspired by Halliday. The theoretical frame of the investigation is founded on critical discourse analysis (Fairclough 1992 & 2001) and Habermas´social theory of the public sphere.The investigation shows, among other things, that the reviews became shorter and easier to read in both paper during the period. The investigation also shows that the genre´s style, composition and contents are relatively stable, and that current ideologies in society have a tendency to be reflected in the reviewers´evaluation of the books. To generalize, the reviews thus developed from a poetic genre in 1964, to become political in the 1970s, academic in the 1980s, feminist in the 1990s and finally an intermedial genre in 2004..

Avblås för torkning av kabel
This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.
Word of Nextopia - en djupare förståelse av Nextopia och hur det påverkar Word of mouth
The purpose of this study is to further develop the understanding of Nextopia, the belief that the next product will always be better, and the effects it has on Word of mouth, both oral (WOM) and electronic (eWOM), and investigate possible causes of this effect. This has been made through an experimental study of responses to two mineral water ads, with a manipulated time frame. First, this thesis supports the fact that there is a general Nextopia-effect on customers being exposed to a future product, which makes them evaluating the product higher in terms of feelings, attitude and intention. Further this study shows that there is also a Nextopia-effect on WOM and eWOM, by customers being more likely to recommend a future product rather than a current one. This propensity to recommend the product also has a relationship with responsibility, which correlates much stronger with WOM than eWOM.
