SMED implementation vid slipoperation

The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.

Elevers förståelse av fotosyntesen och dess koppling till andra organismer

The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.

Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

67,44 miljoner skäl till demokrati : En studie av processerna i EU-finansierade projekt

In a global context the traditional democratic process is facing new challenges. Scholars are talking about a transition from government to governance, where local and regional networks as well as international collaboration are an important part in how regional policy is produced and implemented. In this paper the processes in regional projects funded by the European Union are considered, and related to the traditional democratic process. The study has been fulfilled through informant interviews with representatives from four EU-projects. The interviews are supplemented by a qualitative text analysis of current statutes.

Studie av planerings- och produktionsprocess i sågverksbranschen

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

Hav och Strand : stenteknologi och marin anpassning på Gotland under Senboreal/Tidigatlantisk tid

The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Att göra analoga objekt digitala : En kvalitativ studie om digitaliseringsprocessen i ett bibliotek

Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.

Översvämningsrisker längs Funboån

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

?På sätt och vis är det tydligt, på sätt och vis är det inte det? : en studie om kuratorns upplevelse av sin yrkesroll och det psykosociala synsättet inom habiliteringen

The purpose of this study is to increase an understanding of what prevents the mandatory reporting law, based on the preschool staff's approach to mandatory reporting law about child abuse and neglect to social services, and how these barriers affect their decision to report. The study will also understand what preschool staff experience facilitates the mandatory reporting process and what can be done to improve the process even more. The questions of the study were based on the purpose of the study and have been formulated in two questions:What prevents the mandatory reporting law requirements for preschool staff and how can these barriers be removed? What facilitates for preschool staff to be confident in the decision to report child abuse and neglect, to social services?The study used qualitative semi-structured interviews with five people working at the preschool, including two preschool teachers and three childcare workers. An interview guide was designed as a help to answer the questions about what the barriers are and what it is that makes it easier for the preschool staff, regarding the decision to report cases of child abuse and neglect to social services.The results, based on the five interviews , shows preschool staff's thoughts of the knowledge on the mandatory reporting law, the mandatory reporting process, their perspective of the mandatory reporting law and the uncertainty surrounding the mandatory reporting law.The study's analysis consists of the results that have been analyzed using the theory of social representations, in which the analysis shows an understanding of how the preschool staff act and think about the mandatory reporting law requirements based on their everyday knowledge.

Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
