Strukturering av besiktingsfeloch information : En undersökning av besiktningsbilagor
Inspection errors are nowadays usually written with pen and paper during building inspections. A company in Stockholm is developing a method by which inspections are made digitally from the beginning and where the inspection attachments shall be stored in a database. The idea of this method is that entrepreneurs can use the database to get an experience feedback from previous surveys so that they can improve their production processes. One problem that occurs is how inspection errors will be sorted into the database. They have to be sorted so that contractors or clients can use and sort out the information in a sensible way when they want to evaluate and make improvements in their production processes.This thesis examines how the inspection errors can be sorted in a structured manner.
Filmproduktionsprocesser : En jämförande studie om att filma analogt kontra digitalt
The art of producing films have been around for more than a century and the technology just continues to evolve. But although much has happened in 100 years, there are also processes, theories and practices that look the same now as then. I write this thesis because I want to find the differences between the analogue and the digital way of production. This study is based on a qualitative approach because my ambition is to seek the views concerning film production processes. The advantages of analogue film is that it contains more information than the digital formats and that it has a more cinematic style.
Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
Sammanställning och utvärdering av små avloppsanläggningar utifrån tillförlitligheten hos angivna reningsgrader
The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.
Försäkringskassans förnyelsearbete : en studie av organisatoriskt lärande vid förändringsarbete
The Swedish government corporation Försäkringskassan is currently undergoing large organizational changes. Modifications are made regarding the national insurance system and work procedures. In this study we have investigated the procedures of change with the aim of identifying which pedagogical processes in work procedures that enables organizational learning. Furthermore, the study aimed at gaining insight of how the work procedures enable organizational learning in a learning organization. We have utilized case study tradition to examine specific occurrences in their natural environment to thereby understand the matter of investigation.
Det elliptiska säkerhetsområdets robusthet : hur robust är metoden med de elliptiska säkerhetsområdena förett symmetriskt men icke normalfördelat datamaterial?
Quality Control is a term often used within production and is referring to managing processes so they produce capable products. Within Quality Control, process capability index is a common measure to oversee processes. Safety Region Plots were introduced to do this graphically. In Albing & Vännman (2010) the concept of Safety Region Plots is expanded to incorporate an elliptical shape. The method of Elliptical Safety Region Plots assumes a normally distributed data.
Gropkeramiska lerfiguriner ? stumma ber?ttare om en gemensam v?rldsbild
An archaeological excavation that was made in 2016 of a Pitted Ware Culture settlement at Tr?s?ttra in the northern archipelago of Stockholm was very rich in artefacts and features. Especially unique was the over 300 fragments of clay figurines that were found. Never had so many been discovered at a neolithic place in Sweden. In Scandinavia it is only on the Finnish
islands of ?land that similar figurines have been found.
The aim of this study is to increase the understanding of the clay figurines of Tr?s?ttra and ?land through comparative studies.
Valfrihet inom den svenska hälso- och sjukvården: En studie av patienters beslutsfattande
Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.
Mansklubben inom företagsekonomisk utbildning - En fallstudie om varför så få kvinnor fördjupar sig inom finans
Gender balance within the business administration field at university level is an area that has gained increased attention in the last decade. As gender balance contributes positively to the scientific and educational achievements within all disciplines, many studies have tried to understand the decision-making processes of students when selecting a business specialisation. However, little attention has been devoted to the finance discipline although there is a remaining gender imbalance within the field at higher-level economic studies. This thesis was performed as a qualitative case study and is based on interviews with second-year bachelor students facing their choice of specialisation at the Stockholm School of Economics. Through an application of the Theory of Reasoned Action (TRA), this study aims to examine factors that influence female business students' intentions to choose a specialisation.
Kravbalansering i produktutvecklingsprocesser: Kritisk granskning av en beslutsmodell för produktutveckling
The object for this study is a company developing and manufacturing vehicles for heavy transportation. The company distributes their products on a global market. Therefore the company is required to have efficient internal production development processes in order to successfully beat the competition. The purpose of this master thesis is to study how this particular company intends to implement their standardized theoretical product development process within their organization and how well it is done. We intend to identify and specify if the process has any unexploited capacity.
Undersökning av fosfatsbegränsningseffekter på Escherichia coli AF1000 för bättre förståelse av 3-hydroxybutyratproduktion
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Kommunikationen mellan vårdpersonal och patienter som är döva : En litteraturstudie
The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.
Aktör - Struktur : Förslag till utgångspunkt för studier av samverkansprocesser i förvaltningsområden med naturresurser
The focus on this essay is derived from an international and national dialogue for sustainable development. The recommendation from international level has been to find solutions for governments to implement strategies for sustainable development between local and regional level. This initiative is to improve and stimulate the dialogue between the local inhabitants, officials, entrepreneurs and stakeholders in the communities together with the authorities on the regional level. The purpose is to share knowledge and find ways to learn about the natural systems and how to co-operate in the work of preserving the natural resources and developing different processes for a sustainable development. Many scientists? today stress the importance that ecosystem resilience is promoted by biodiversity conservation and that we need to find solutions for local ecosystem management practices.This essay aims to find theoretical approaches and perspectives that can be used in a wider framework to study co-operative processes between the local (agent) and regional (structure) level.
Produktivitet och personalplanering : - en fallstudie på Onninen AB 2008
During the last couple of years many sectors and markets have had an increase in the competitive situation, this has meant that being cost effective have become more essential if organizations want to stay in business and be competitive. Thus, one crucial issue has become how to utilize the resources already available within the organization. Organizations can thoroughly plan and control personnel resources in order to become more efficient. But to become more cost effective also means taking into consideration several key figures, productivity being one of the more important figures.Onninen, a wholesaler which has one of its two central warehouses in Örebro has experienced this issue, i.e. an increase in competitive situation in their market.
Riskbedömning och naturligt producerade dioxiner
The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.
