Undersökning av metoder för att analysera och modellera efter stora datamaterial, hantering av programmet SPSS samt en studie i Kronoberg läns gymnasieelevers psykiska ohälsa
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.
Utveckling av dataanalysprogram för Opcon Powerbox
Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.
ISO 14001 : Från ledningsbeslut till certifiering
Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.
SYNS VI I SVERIGE? : En rättssäkerhetsstudie om barn i migrationsprocessen
The current thesis is on the rule of law and how the principles of the rule of law are met in thenew Swedish migration process. The migration process has been subjected to criticism duringseveral years and on different occasions. The migrations process is viewed through a ?rightsof the child? perspective, foremost to seek if the rights of the child are met. The children are avulnerable group, not the least in the process of migration.
Generationsskräpsamling med explicit kontroll av hårdvarucache
This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..
SELF CONTROL
SELF CONTROL är ett undersökande examensarbete i textildesign. Med en textil hantverksmetod undersöker jag mötet mellan kontroll, tidsåtgång och material. Detta med utgångspunkt i en feministisk diskurs. Jag ser kontroll som något som exkluderar, censurerar och begränsar möjliga uttryck inom textilt hantverk på samma sätt som kvinnokroppen kontrolleras i ett patriarkat. Jag har använt mig utav en performativ och repetitiv metod som aktivt har gått ut på att bryta mot föreställningar om hur hantverket ska utföras.
En agil arbetsmetod för utveckling av ett leverantörsstöd
This thesis was made possible by the company Verendus system AB, which is the leading developer of dealership management systems in the caravan and camper market. The goal of the thesis was to create a statistics module for a new producer system envisioned by Verendus. The new system is aimed at manufacturers and importers of caravans and campers, with the goal of enabling its users to create more effective production lines. By providing statistical data to mentioned users they will be able to predict market trends and customize their production lines accordingly. Today such software does not exist which leads Verendus to think that its arrival would lead to a success on the market.Before the development and design of the producer system began, a new agile method had to be developed, MAM (Minimum Agile Method).
Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller
Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.
Förändrat omhändertagande av patienter med uretärsten : - Lärdomar från ett förbättringsarbete
Bakgrund: Omkring 10-15 % av befolkningen, oftast i arbetsför ålder, riskerar att någon gång drabbas av njursten. Nationella riktlinjer för njurstensbehandling saknas, men studier stödjer behandling inom 48 timmar för snabb symtomlindring och minskade besvär för patienten. Inom studerad verksamhet var tiden från diagnos till behandling lång och återinläggningarna var många, varför ett förbättringsarbete initierades.Syfte: Syftet med förbättringsarbetet var att halvera tiden från diagnos till behandling för patienter med akut behandlingskrävande uretärsten, samt minska negativa effekter relaterade till obehandlad uretärsten. Vidare syftade studien av förbättringsarbetet till att beskriva ett tvärprofessionellt teams erfarenheter av aktuellt förbättringsarbete gällande patienter med uretärsten.Metod: Ett tvärprofessionellt team bedrev förbättringsarbetet med stöd av Nolans modell för förbättringsarbete, vilket studerades genom en deskriptiv fallstudie med induktiv ansats. Effekterna av förbättringsarbetet utvärderades med Statistical process control (SPC).
Finansiering av småföretags internationalisering
AbstractAccording to several researchers finance is scarce, scarcer for small businesses than for big enterprises. Small and medium-sized enterprises, SMEs, that want to start exporting and sales or manufacturing abroad need capital to get ready. Which capital structure and financial costs do they have, and which forms of finance do they actually use for that purpose. New american research by Mansi, Reeb (2002) has suggested, that there is a positive connection between leverage and a negative one between financial costs and internationalization, and that a non-linear model better describes this connection.This study has gathered data in two ways: Through a questionnaire from 37 SMEs and balance sheet figures from totally 166 manufacturing SMEs. In order to examine, whether the company was active on the international market, 200 SMEs in south Sweden were asked, if they exported to, produced or sold on any other market than their home market.
Ett samhällsengagemang som Skapar Shared Value - En studie om hållbarhetsstyrning och Creating Shared Value i en svensk kontext
This study investigates the corporate sustainability activity, linked to the company's core business, which is a relatively unexplored field in a Swedish context. The study examines how the organization has used management control for its sustainability activity within two social initiatives; and whether these initiatives have generated value for the organization and involved stakeholders. Management control of social initiatives are examined within the theoretical framework of The Sustainable Balanced Scorecard and the organization's value creation contributions are outlined in accordance with a definition of the concept of Creating Shared Value. The method used for the implementation of the study is a qualitative study, embodied in an illustrative case study of a large Swedish company operating within financial sector. The empirical data was collected through 12 in-depth interviews with representative interviewees within the organization and with other stakeholders involved in the company's social initiatives.
?Daddy?, from Vision to Video
?A designer rarely works alone?. The first sentence of Jonas Löwgren and Erik Stolterman's chapter on design as a social process made me curious. What if a designer worked alone? What are the actual differences between working on a project alone and as part of a group? How would it influence the creative process? What would be different when coming up with ideas, meeting with clients and setting deadlines? Does the influence of another designer stifle the individual creativity or does it actually nurish it? This paper is written to answer these and other questions as well as take you through the creative process of the production of ?Daddy? - the music video..
Trauma and coping - A study of women that were trafficked for the purpose of sexual exploitation in India
This study was conducted in the red-light area of Pune city, India. The target group of the study is sex workers that are victims of human trafficking for the purpose of sexual exploitation. The purpose of this study was to examine the initial and continuing trauma and its effects, and the coping strategies that these women develop in order to survive. The initial trauma occurs during the trafficking and seasoning process in the brothel. The term continuing trauma refers to violence and psychological trauma that are part of sex workers lives.
Processdatorsystem för tryckreglering
The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..
Magnetfältssignaturer från Birkelands- och jonosfärsströmmar
This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.
