Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor
Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..
MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP
Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.
Internationell jordbruksmark till salu - Nationell suveränitet, fattigdomsbekämpning & visionen om en hållbar utveckling
During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.

Data were analyzed with content analysis. In the result there was shown two themes.
"In i sagans land" : Aktionsforskning i bibliotekspraktiken med syfte att utveckla sagostunden
The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.
Illustrerad samtid : En studie av hur tre filmer skildrar 1960-talets Sverige med särskilt avseende på konsumtion och välfärd
This paper studies how the ?Swedish model? has influenced the Swedish community during the first half of the twentieth century and how living with this model was like in the 1960s. During the ?60s the laws and reforms created by the ruling socialistic party, SAP, dominated the Swedish society. Their goal was to build Per Albin Hansson?s vision of a welfare state.
Utveckling av en ytmonterad fördelningsmätare som underlag för individuell debitering av vattenförbrukning i fastigheter
The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

The instrument used was the Team Diagnostic Survey developed by Ruth Wageman, J. Richard Hackman and Erin Lehman (2005) in order to diagnose the strengths and weaknesses in work-groups, as well as explore the group?s behaviours and effectiveness. The results show that there was a significant difference between the Karlskrona Kommun groups and the larger population of Swedish groups in the following areas: stable, clarity, challenge, diversity, whole task, resources and availability..
Skyltfönstrets möjligheter - En kvantitativ studie om skyltfönster baserad på kreativitet och tid -
Store windows, as many earlier research studies indicate, is an important factor of the store atmosphere to attract customers into the store. In this study we have narrowed it down and chosen to focus on how different contexts of the store windows will effect customers' evaluation. The purpose is to find out how the context of high creativity and low creativity combined with different time aspect in store windows will affect store image, attitude, entering decisions and purchase intention toward the store. The results are based on a quantitative study where we did an experiment and a field study. The result shows that higher level of creativity is better than lower level of creativity in certain aspects.
Oreglerad=Fri? En studie om Läkarkliniken
The discrepancy in the rights for healthcare between undocumented migrants and the citizen in Sweden is a prerequisite for the existence of Läkarkliniken. Because of the chosen patient group the clinic stands outside the regulations from the National Board of Health and Welfare. The aim of this study was, from an institutional perspective, to investigate how such a unique player is designed and where the influences to the design origin from. The task was conducted thorough a qualitative case study with base in depth interviews. High levels of isomorphism were observed between Läkarkliniken and the general healthcare, however differences were seen as well.
Fonologisk medvetenhet i förskoleklass : En interventionsstudie
International studies show that literacy skills have deteriorated among Swedish students. Empirical evidence states that before being able to learn to read it is important to have phonological awareness. From this perspective, an intervention study was launched to examine whether pupils´ phonological awareness could be enhanced through the work of a special model during a limited time. The aim of the study is to investigate whether six pupils in preschool develop phonological awareness based on Bornholmsmodellen during a limited period of time. The control group was made up of the remaining pupils in the preschool class.
Urshults Knektar : En studie om vad som hände de indelta knektarna från Urshults rotar 1709 till 1718
This essay examines what happened to soldiers from Urshult in military service of Sweden during the diminished power of the country in the beginning of the eighteen century. Information of interest is taken from the soldiers? age, time of service and other annotations of interest that shows to be helpful when examining their fate. First off, this study explains Sweden?s situation during this period of time. To get a grasp about the situation, allotment is explained as well as the most important events in the big Nordic war. This study is based on qualitative content analysis and GMRs are used as its main resource of information and consists of empiric analysis.The result of this paper shows that very few soldiers from Urshult were able to return home alive.
Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system
For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.
Jämförande simulering och modellering av framtida järnvägars elenergiförsörjning
In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.
Aldrig för sent : verksam pedagogik för vuxna med läs- och skrivsvårigheter
Att det aldrig är för sent att utveckla sin läs- och skrivförmåga är det bärande temat i denna uppsats. Syftet är tvåfaldigt: dels är avsikten att skapa en förståelse för de svårigheter vuxna med läs- och skrivsvårigheter har att brottas med, dels att lyfta fram de framgångsfaktorer som, enligt verksamma pedagoger i vuxenutbildningen, präglar effektiva utbildningsinsatser för vuxenstuderande med läs- och skrivsvårigheter.I tre litteraturstudier belyses läs- och skrivsvårigheter hos vuxna utifrån olika perspektiv. Översikt ett beskriver hur vuxna med läs- och skrivsvårigheter uppmärksammas i olika styrdokument för vuxenutbildningen. I översikt två redogörs för det komplexa fält som läs- och skrivsvårigheter hos den vuxna individen utgör och i den tredje översikten åskådliggörs självbildens betydelse för individer med läs- och skrivsvårigheter.I en enkätstudie ges en bred bild av hur 35 pedagoger som arbetar med särskilda insatser till vuxenstuderande med läs- och skrivsvårigheter betraktar sina insatser, vad de exempelvis lägger vikt vid i sin undervisning, vilket behov av kompetensutveckling de har och, inte minst, vad de räknade som framgångsfaktorer för effektiva insatser.Enkätstudiens resultat bekräftar i stort den tidigare forskning som gjorts inom området när det gäller effektiva insatser. Praktiska förutsättningar i form av ett inbjudande ?yttre rum? med möjlighet till lugn och ro, ?time on task? samt tillgång till teknisk kompensation anges som viktiga villkor för en framgångsrik lärsituation.
