EMC problematik och el-kvalitet i elkraftnät
The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
Faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighet- och styrketräningsprogram: En beskrivande litteraturöversikt
Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning.

Syftet med litteraturöversikten var att genom att granska vetenskaplig litteratur i området beskriva faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighetoch styrketräningsprogram. En beskrivande litteraturstudie gjordes på ämnet. En litteratursökning genomfördes mellan 6-24/9, 2014 i databaserna Scopus, Proquest, Pubmed, Cinahl, AMED, Web Of Sciense.
Organisationsförändring : hur agil projektledning kan bidra till att motståndet minskas
Metod/Method: Semistrukturerade intervjuer har genomförts med kommunchefen, personalchefen, fyra medarbetare och en facklig representant i Sala kommun. Materialet från intervjuerna analyserades sedan bland annat med hjälp av två av Morgans organisationsmetaforer, Kotters 8 steg, agil projektledning och Derbys tidigare forskning inom området./ Semi-structured interviews have been conducted with the local head of government, the human resource manager, four employees and a union member in Sala kommun. The material from the interviews was then analyzed with help from Morgans organizational metaphors, Kotters 8 step, agile project management and Derbys earlier research on the area. Slutsatser/Results: En organisationsförändring enligt agil projektledning innebar att de teoretiska rekommendationerna för hur en organisationsförändring ska genomföras följdes. Att personalen gjordes delaktig i förändringen gjorde att motståndet mot organisationsförändringen kunde minimeras vilket var den största fördelen.
Automatisk tesauruskonstruktion med latent semantisk indexering
The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.
Från underhållning till motstånd. Om kvinnors läsning av Harry Potter-böckerna
The purpose of this study is to examine how women?s reading of the Harry Potter books can be understood on the basis of gender theory and reader-response criticism. The empirical data is gathered through qualitative interviews with six female Harry Potter readers between the age of 21 and 35, and is analyzed through several theories regarding gender and reading. The results show that the readers are critical towards many aspects of the books, especially when it comes to the stereotyped depiction of women and men. The books are said to reproduce the gender dichotomy, the gender hierarchy and the heteronormativity in society.
Att optimera samhället inför klimatförändringar : Sårbarhet och anpassning på dagordningen
This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..
Chefskap, administration och IT - Hur går det ihop? : En kvalitativ studie av hur enhetschefer inom kommunal verksamhet upplever IT-system
The increasing administration in IT-systems is the target of much debate today. It is viewed as taking time from what is considered to be managers? real tasks as well as resulting in an ineffective and stressful work environment. This view of IT-systems as problematic and time consuming can also been found among unit managers in a municipality in the north of Sweden. To be able to understand why IT-systems are perceived in this way this study?s aim has been to find what leads to this view.
Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar
Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.
Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga
This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..
Effektivisering av informationsöverföringen i läkemedelskedjan
This report is the documentation of a project in the education Master of Science in Mechanical Engineering. The project was carried out at Alfakonsult AB. The purpose of the project was to map out the transference of information between the different operators in the supply chain of medicine in Sweden and to analyse this in order to reduce lead-time and the total throughputtime. The supply chain of medicine in Sweden consists of producers, distributors, one wholesaler, prescribers and patients. The mapping of the transference of information showed that most operators in the supply chain have done well introducing technical aids to facilitate the transference of information.
Varför tror vi att vissa företagär mer hållbara än andra? : - En studie om hur företags motiv och kommunikation kringhållbarhet är relaterat till konsumenters uppfattning
The number of elderly in Sweden is increasing due to improved living conditions and better medical care. It is important that society adapts to the increase and begins to work preventively to reduce the costs of the increase. An important aspect is the elderly accommodation, the cost of health care in specific accommodation is almost twice as high as those for ordinary housing. Therefore, it is important that we availability adapt dwelling to allow older people to live in ordinary housing for as long as they wish, instead of moving to assisted living before they need it. If we can fulfil the elder?s needs with home care instead, society can save a lot of money.In this report, three different forms of housing has undergone accessibility increases and been inventoried and analysed.
Sjuksköterskors erfarenheter av att möta patienter med prediabetes : -En kvalitativ intervjustudie
Background: Prediabetes is caused by relative insulin deficiency and insulin resistance in the body tissue which leads to abnormal blood glucose levels. Prediabetes can over time lead to type 2 diabetes mellitus. To prevent the onset of type 2 diabetes and its complications, it is important to identify early elevated blood glucose levels and thereby prediabetes.Objective: To describe nurses' knowledge and experience regarding the management of patients with prediabetes.Methods: Qualitative descriptive design with individual interviews. Three nurses, three community health nurses and three diabetes nurses were interviewed.Results: The result can be understood from the nurses' experiences of encountering patients with prediabetes. An overarching theme in the analysis was that the nurses are working or aspiring to work preventively.
Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk
During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.
Passage Retrieval en studie av index
The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.
Säkrare byggarbetsplatser : En rapport om arbetsmiljö i allmänhet och fallolyckor i synnerhet
In Sweden there are 299 000 working in the construction industry. The construction industry is one of the industries where most accidents occur every year. During the last ten years there have been 111 death accidents in the construction industry and 48 of them were falling accidents. That means, in average, one death accident every month.Falling accidents gives serious injuries to the persons who are affected by them. It is anticipated that this report will investigate the factors beyond the falling accidents and also to present proposals that can decrease the number of falling accidents in the future.To secure a healthy and safe construction site it is of great importance that both the employers and the employees cooperate towards the same goal.
