??Tidsserieanalys över svensk varuhandel januari 1975 ? augusti 2010
Syftet med denna uppsats är att modellera och prognostisera Sveriges varuexport, varuimport och handelsnetto. Vi använder oss av data från januari 1975 till och med augusti 2010 för respektive serie. Dessa data testas och jämförs i olika ARIMA- och SARIMA-modeller samt skattas även medelst säsongsreningsprogrammet TRAMO/SEATS. För de modeller som bäst passar serierna genomförs därefter in sample- och out of sample-analyser med felmåtten RMSE och MAPE. Modellerna med bäst felmått och som därpå väljs ut för att göra prognoser för serierna till och med augusti 2012 är (3,1,0)x(0,1,1) för export, (2,1,1)x(0,1,1) för import samt (0,1,1)x(0,1,1) skattad i TRAMO/SEATS för handelsnetto..
Produktivitet i robotcell
The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.
Kulturen och kapitalet Hur, vad och varför ett antal män läser
This thesis deals with the leisure-time reading of fourteen men with two different occupations, teachers of technology and directors of companies. The main reasons for writing the thesis are that very little is written about mens reading habits and also statistics that tell that mens reading decline regardless of educational level. The purpose has been to compare the reading and relations to literature between the two groups of men and to find out if any differences have to do with factors such as social background or age. The questions we have asked our collected data has been what, how and why the men read. We have tried not to investigate the work-related reading although we are aware of the difficulty in separating this from the leisure-time reading.
Simulering av ett värmesystem i COMSOL Multiphysics : Pipe Flow Module
Syftet med detta arbete är att simulera ett värmesystem i COMSOL Multiphysics, Pipe Flow Module, Non-Isothermal Pipe Flow som innehåller ekvationer och randvillkor för att modellera inkompressibel strömning och värmeöverföring i rör.Data om processen och dess komponenter har samlats in från industrin där arbetet är utfört och i vissa fall modifierats för att bättre beskrivas i programmet.Utifrån insamlad data har en modell byggts upp och två simuleringar har gjorts. En stationär för starten av systemet, den har sedan legat till grund för en dynamisk som simulerar förloppet från start till normaldrift.Tiden det tar för det aktuella fallet att nå drifttemperatur är 16 timmar. En felströmning upptäcktes samt att en av pumparna inte kommer att klara en start från 20 °C..
"Lets Play!" : En studie av kunskapsöverföring mellan digitala spel och musikinstrument.
The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.
Lika rättigheter och möjligheter? - Kommuners personalpolitiska arbete på de olika diskrimineringsgrunderna.
The study is aimed at investigating the Slovenian philosopher Slavoj ?i?eks theories ofthe ontology of the subject, the crisis of our modern society and his views on how theology,especially Christian theology, can provide the answer for the threats to our society.My main object is the article Descartes and the post-traumatic subject (2008)where ?i?ek elaborates thoughts about the subject and our capitalistic society. To be ableto grasp these thoughts in full I have undergone an investigation not only on the writingsof Slavoj ?i?ek, but also on the philosophers to whom he owe much of his theories,such as G.W.F. Hegel, Friedriech Schelling, Karl Marx and Jaques Lacan.In the study I have shown how the subject is, according to ?i?eks psychoanalytictheories, decentered.
En studie om sociala medier och perception
Earlier studies and research on the subject of perception and social media during the working process resulted in a change of the problem. At first the focus of the study was to examine how social media affects the perception of a brand although later on the problem had to be developed to instead examine if social media reflects the perception of a brand. The purpose of this study is to figure out if social media reflects consumer?s perception of a brand. This will contribute to company?s knowledge on how important social media is in their branding and will give pointers on how many resources that is necessary to spend on branding in social media.
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.
Estimering av kreditbetyg - Syntetisk rating med Ordered Probit Model
Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.
Islam och folkmaktens gränser. : En undersöknning av Sayyid Qutbs, Mawlana Mawdudis och Ali Shariatis teologiska uppfattningar.
English abstractTitle: Islam and the limitations of the public will of choice.The purpose of this paper have been to investigate how three modern Islamic theorists view the limitations of the public free will of choice based upon their interpretation of the Islamic theology and doctrine.The paper focuses to highlight how all three chosen Islamic theorist interpret the Islamic doctrine based upon my elected theses and more specifically pinpoint were the free will of choice ends, and Islam as a religion starts to take hegemony. The paper?s aim is to further an understanding that in the modern world and as a effect of increased literacy, Islam has been somewhat inclined to split into several Islamisms, based upon the variety of fatwa?s on the Islamic doctrine that is available online. Therefore it remains to the modern day Muslim, to individually decide whether they choose to follow the message of the Holy revelation in the Quran or trust a mufti?s fatwa in their everyday life as a Muslim.The material used and analyzed in this paper is prime source material.
Private brands on special display
This thesis is concerning private brands on special display. ICA Gott Liv! was used as a study object and a latin square design was employed, using 2 ICA Kvantum stores. Two displays were built in order to compare which created the most awareness and interest, one with the best selling Gott Liv! product and one with four randomly chosen Gott Liv! products. The data was collected using triangulation, questionnaires, sales data and observations were conducted in the two stores. The results indicated that private brands works as well as manufacturer brands on special display and a display with four randomly chosen products creates more interest and higher sales than the display with the best selling product..
Modellering av oorganiskt kol i boreal jord och vattendrag med hjälp av PHREEQC : Modelling of dissolved inorganic carbon in boreal soils and streams using PHREEQC
Syftet med examensarbetet har varit att studera kol i mindre vattendrag med hjälp av jämviktsmodellering i PHREEQC. Fokus har varit dynamik av löst icke organiskt kol (DIC) samt att förstå hur mycket koldioxid (CO2) som avges från mindre vattendrag och om den mängden har signifikant inverkan på den globala kolbalansen. Med hjälp av provtagen data från Krycklans avrinningsområde år 2003-2007 och 2009 har modellering av DIC och pCO2 utförts med målet att se förändring både över säsong och nedströms i ytvattensystemet. För att utvärdera modellen har tillhandahållen data över uppmätt pCO2 använts. Målet var att jämföra modellerade och tillhandahållna pCO2-värden för att se hur väl modellen kunde beskriva verkligheten och om den fungerade bättre för någon plats eller under vissa delar av året.
