Ger olika temperaturförhållanden ¨trade off¨- effekter mellan tillväxt och exokutikulans tjocklek hos Gammarus pulex? En pilotstudie
I rinnande vatten, så som bäckar och åar, har Gammarus pulex en viktig ställning i näringsväven. Arten bidrar till att bryta ner organiskt material och göra energin i detta tillgänglig för andra organismer. G. pulex är dessutom en viktig föda för ett stort antal predatorer. Flera studier visar att G.
Prediktion av villapris och dess faktorers inverkan.
A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..
Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Method: The study is conducted through three surveys; the first two were face interviews with companies that sponsor Swedish soccer teams and the third study was conducted with a questionnaire to supporters outside a soccer stadium. Results: A model that would better reflect the reality of today (2013) could contain company pride, chairman?s whim, exposure, relationships and associations..
Modellering och reglering av drivenheter i gaffeltruck
To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.
Management på mellannivå-en fråga om ett tudelat arbete? En studie på Trade AB.
Uppsatsens syfte att dels att beskriva vad begreppet management innebär för mellancheferna på det studerade företaget, dels att peka på de konsekvenser som kan följa av detsamma. I uppsatsen har en kvalitativ metod använts med krav på kritisk reflektion. Det empiriska underlaget består av åtta intervjuer med chefer inom ett medelstort svenskt företag. Inom Trade AB råder en tudelad syn på mellanchefsrollen. Denna präglas i första hand av en sälj-och specialistroll och utesluter en integration av chefsrollen, i vilken management inte bara upplevs som personalvård utan som en naturlig del av mellanchefens arbete.
Fastighetsbranschens kapitalstruktur : En totalundersökning av Stockholmsbörsens fastighetsbolag, hur deras kapitalstruktur har påverkats av övergången till IFRS
Syftet med uppsatsen var att undersöka om det fanns något samband i kapitalstrukturen hos fastighetsbolagen på stockholmsbörsen. Samt att se hur införandet av IAS 40/IFRS har påverkat företagens kapitalstruktur.Författarna valde att göra en totalundersökning för att belysa problemställningen på bästa sätt. Vidare letade författarna i företagens årsredovisningar för att hitta de siffror som behövdes för att räkna ut de relevanta nyckeltalen. De nyckeltal som författarna ansåg lämpliga för undersökningen var soliditet, avkastning på eget kapital, avkastning på sysselsatt kapital och skuldsättningsgraden. På vissa av nyckeltalen ansåg författarna att det fanns ett intresse av att se hur korrelationen och standardavvikelsen såg ut, därför räknades dessa också ut.
Katalog vs Nätbutik ? en studie om produktpresentation av modevaror inom distanshandeln
The survey Distanshandeln idag 2005, made by the Swedish postal service, tells us that web shops started to pop up in the 1990´s and began competing with the catalogue sells in the end of the decade. Ten years ago, it was said that the web shops would take over the distance trade market. Today we know that did not happen. Internet shopping accounted for 4, 2 % of all distance shopping in Sweden last year. Our inquiry is guided by the observation that the catalogue is still in use and moreover, it seems to have changed very little from when we were kids.
Granskning av Solibri Model Checker - En Svenskanpassning : Ja?mfo?relse av tva? egenkontrollsystem
The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models.
Fackförbunden och livslångt lärande : Kritisk analys av livslångt lärande ur ett fackligt perspektiv
Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..
Representeras ditt yrke? : - en kvantitativ studie om vilka yrken som representeras mest respektive minst i facktidskriften DIK-forum
The aim of our study has been to see how DIK-forum represents the occupational groups that are represented in the frames of the trade journal. We have, to find out the phenomenon, done a content analysis by looking into 18 numbers of DIK-forum from year 2006 and 2007. The 18 strategically chosen journals was enough to give us a statistic result that we later on could generalize over those two years of DIK-forum. Totally there were 818 articles, news items and vacant advertisements that made the central point of this study. By these materials have we studied the representation of the occupational groups to find out if there were any over- and/or under represented groups, and also if the publications of the material were directed to the students or to the occupational groups in these trade journals.In our study the results shows that the trade journal DIK-forum does not represent all the occupational groups at the same level.
Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012
This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Dynamisk modellering av kärnreaktor
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Terrorism i svenska tidningar : en diskursanalys av Aftonblader, Dagens Nyheter och Svenska Dagbladets rapportering från terrordåden München 1972, Lockerbie 1988 och World Trade Center 2001
Vårt syfte med undersökningen är att undersöka hur de diskursiva praktikerna ser ut för terrorrapporteringen på 1970, 1980 och 2000-talet, vi kommer särskilt att fokusera på beroendeförhållandet mellan terrorism och massmedier. Vi har valt ut tre terrordåd, München 1972, Lockerbie 1988 samt World Trade Center 2001. Vid varje terrordåd har vi tagit två artiklar vardera från tidningarna Aftonbladet, Dagens Nyheter och Svenska dagbladet. Det blir totalt arton artiklar som vi har använt oss av. Terrorism lever i ett beroendeförhållande till massmedia.
