I detta examensarbete har en generell metodik skapats för testning av styrsystem för pumpar. Testmetodiken beskrivs med modeller som på ett strukturerat sätt går igenom testningens förberedelse och utförande. Metodiken tillämpas sedan genom en stegvis mall för hur testningen går till praktiskt.En metod för att optimera antalet tester presenteras. Denna metod minskar antalet tester genom att använda de mest prioriterade signalerna som skickas mellan styrsystem och pump. Denna prioritering sker genom en viktning av hur viktig signalen är för systemet.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

Titel: Skjut inte på Kulturtanten med hagelbössa - hon kommer ändå!Författare: Zara Selander & Isabella WestbergUppdragsgivare: Arts & Business Sweden ABKurs: Examensarbete i Medie- och kommunikationsvetenskap, vid Institutionen förjournalistik, medier och kommunikation (JMG), Göteborgs universitetTermin: Höstterminen 2013Handledare: Orla VigsöAntal ord: 18 712 (exklusive abstract, executive summary, appendix)Syfte: Undersöka hur verksamheter inom scenkonst i Göteborg arbetar med extern kommunikation för att skapa en relation med sin publik. Samt identifiera och lyfta fram faktorer som kan inverka.Metod: Kvalitativ studie med samtalsintervjuer med marknads- och kommunikationschefer på sju valda scenkonstverksamheter i Göteborg.Material: Analys av samtalsintervjuer, sammanlagt 7 personer.Huvudresultat: Studien beskriver en professionaliserad extern kommunikation med relationer och dialog i fokus. Scenkonstverksamheterna kommunicerar med en bred publik såväl inom fysiska väggar som i digitala medier. Arbetet påverkas av fem huvudfaktorer somstudien identifierar: organisationens struktur, ett offentligt uppdrags ramar, digitalisering, utbudet av konkurrerande kulturaktiviteter samt människans komplexitet. Nämnda faktorer ställer höga krav på scenkonstverksamheterna att hålla en ständig dialog och kommunicera till breda grupper i en mängd kanaler.

This report describes the process of developing a user-friendly and responsive archive website. The website is a Hi-fi prototype and was created for the company JG Communications, to serve as an archive for their customers? style guidelines. To create this website I have used HTML5 and CSS3 to make it responsive for various computer screens. I have also used PHP and some JavaScript to make some of the functions and Adobe Photoshop and Illustrator to make design elements for the prototype.

The web has a broad affect on the global economy and can among other things be used for web based information systems (WIS). These systems have grown from being used as a market platform to support all activities in the work of an organisation of today. To survive in a turbulent competitive environment, companies must start to cooperate with their customers instead of just collaborate with them. Can an IT-consultant company use a WIS as a tool for keeping in contact with existing customers to attain this cooperation? A WIS could strengthen the relation between customer and supplier and through that have a possibility to increase the customer use since it can facilitate business processes and imply that services can be offered in a new way.

The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.

The objective of this project was to develop an application for mobile phones using the Android operating system. The main goal was, with the help of GPS, to pinpoint locations, measure distance traveled and illustrate the progress on a map. Functionalities for just showing the map, fetching addresses and saving to a database was also implemented. The result of the work was a proper application, called MeasureApp, that fulfills the goals set in the planning stages of the project. MeasureApp can be used to measure distances where accuracy is not a main factor, i.e walks or runs.

Homework is and has always been a part of school work. It may take a lot of time from the pupils? leisure. Despite this, you cannot find anything written about homework in the curriculum. How can this be? Is homework necessary and what is its function?The purpose of this study is to find out how a few teachers in primary school reason about homework.  What are their attitudes towards homework and what functions do they see?To get an answer to this I studied literature and research reports, and did four qualitative interviews with teachers who teach grades 1-6.The results show that all the teachers give homework to their pupils, but their opinions about homework differ.

The purpose of this paper is to analyse how work by Swedish artist Ylva Ogland (born in 1974) function as an eye-opener for the social marginalisation of people identified with homosexuality, prostitution and drug addiction. Although highly present in reality, these phenomena were historically, and are still today, hidden from view in public discourse. I have focused on the installations Rapture and Silence and Things Seen, and the still-life painting called Xenia. I argue that these artworks carefully represent the above-mentioned marginalised groups, by way of references to comparable motives in the history of art, from neoclassicism in France, to realism and romanticism..

With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..

This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.
