Scrum ? en fallstudie från lokala företags perspektiv
Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.
Modell av en synkronmaskin för PSCAD/EMTDC med magnetisk mättning i d-led och elektriskt gränssnitt för fältmatare
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder
This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..
Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark
Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.
Utveckling av en matematiklaboration på Vetenskapens hus : En tillämpning av gruppteori på molekylär symmetri
This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ?The House of Science? that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ?molecular symmetry? as well as the underlying pedagogical theories used to describe learning processes in creative contexts.
Feberkramper hos barn - Sjuksköterskans preventiva arbete / Children with febrile seizures - The nurse?s preventive work
Background: Febrile seizures are common in childhood. When a child is stricken with febrile seizures it is not only the child that is suffering, in fact the whole family is affected. There are different ways to prevent recurrence of febrile seizures, such as use of different drugs. The parents also need information about febrile seizures and support from the nurse. Aim: The aim of this literature study was to illuminate the nurse?s preventive work for children who have been stricken with febrile seizures.
Kapacitetsberäkningsmodell för materialhanteringsflödet på Ericsson i Kumla
Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.
Scrum ? en fallstudie från lokala företags perspektiv
Through a case study, I wanted to find out what advantages and disadvantages
local companies consider with scrum and what they think about its future.
To find out what scrum is, I read the literature and scientific articles and
then wrote surveys based on my thoughts.
Further, I also wanted to find out if it?s possible to use scrum in a school
environment and therefore I visited a high school class who used scrum in one
of their projects.
The result was good but could have been better as it requires more training of
scrum to understand everything.
The surveys were distributed to various local companies. After having received
a lot of answers, I concluded that the clear priority was the most positive
feature of scrum and the most negative was that it was difficult to get the
rest of the organization to understand scrum, which creates problems.
Both high school class and local companies believe in scrum?s future, even if
they think scrum will be partially modified to adapt to the
software-development in the future.
According to the survey responses, the most important to get the projects to be
successful both now and in the future is that everyone who work with scrum is
right educated..
Vad styr den etiska fondefterfrågan? : Om vilka faktorer som som påvekar den etiska fondförmögenheten.
This paper examines what affects the demand for five Swedish ethical funds between the years 1997-2007. The purpose of this study is to examine if there is a relation between fund value and other values than just financial. This study examines if the number of conflicts in the world and the media?s coverage of the climate change debate could have an impact on the demand for ethical fund. A multiple linear regression shows that we don?t have a significant result from the examined variables except for household wealth.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.
Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk
In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.
Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.
Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease
Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.
Product Development Processes in the Nordic Paper Packaging Companies : an assessments of complex processes
It is important for firms to continually develop their offerings as the business landscape develops in order to sustain their competitiveness (e.g. Schumpeter, 1934; Ansoff, 1979; Porter, 1985; Trott, 2012). In a context of globalization, rapid technology development and changing customer needs, the paper packaging industry is urged to enhance its product development activities (Hansen & Niskanen, 2007; Björkdahl & Börjesson, 2011). However, there is little research about paper packaging firms? product development processes (ibid).
Från Bomull till Byxor Livscykel Inventering och Ansvarsfullt Företagande En MFS i Södra Indien
A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India?s knitwear exports to Western Europe.
