Utveckling av ett centraliserat informationssystem
CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.
Det implicita avkastningskravet på Stockholmsbörsen: En jämförande empirisk studie med avseende på antalet börsintroduktioner för 1999 och 2012
This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

Re-design av kommunikationsbyrån Åkesson & Currys webbsida : En rapport som beskriver produktionsprocessen för kommunikationsbyråns nya webbsida
Den här rapporten redovisar produktionsprocessen för en re-design av en webbsida. Kommunikations-byrån Åkesson & Currys webbsida har funnits i över fem år. I dagsläget tycker inte företaget att webbsidan representerar vilka de är, därför var ett led i produktionsprocessen att undersöka hur de ser på sin identitet. Målet var att med en ny vision av Åkesson & Currys identitet producera ett designförslag över en webbsida som presenterar dem på ett representativt sätt. Re-designen ska möjliggöra att användaren blir intresserad av byrån och gärna initierar till en ny kontakt med Åkesson & Curry efter ett besök på webbsidan.
Energieffektivisering i offentliga byggnader : Jämförelse i elanvändning för ventilation med olika luftflödesstyrsystem
I got interested in this subject when I came in contact with Västtrafiks new paymentsystem myself during my visits in Gothenburg. I suspected problems with the informationmaterial regarding it and others seemed to share my opinion that the payment system wasdiffcult to understand. When I contacted Västtrafik and asked them about the paymentsystem they confirmed that some understanding diffculties had occurred. With thatconfirmation I decided to make it my project to look in to the matter.Some methods were used to identify the problems. The methods could again confirm thatthere were some problems with the payment system and that the information material wasa vital reason.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Automatisk plastlisthanterare
Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.

Kravhantering med hjälp av Use Case
Detta examensarbete ger en introduktion till området systemutveckling. Kravhantering har i alla tider varit en viktig del i systemutveckling. För att kunna lyckas med kravhanteringen under ett systemutvecklingsprojekt är det viktigt att använda sig av rätt teknik. En teknik som finns för att kunna hantera de krav som ställs på ett system är Use Case som härstammar från UML. Syftet med detta examensarbete var att ta reda på de för och nackdelar som har upplevts av användare som har arbetat med Use Case i samband med kravhantering.
Pensionären och paddan : En studie av pensionärers upplevelser av läsplattor
Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.
Free Valve Technology : ? Utveckling av ett styrsystem för ett elektronisk styrt pneumatisk-hydraulisk ventilsystem på en förbränningsmotor
Detta examensarbete är utfört på uppdrag från AVL Södertälje Powertrain Engineering AB.Målet med arbetet har varit att utveckla ett styrsystem för ett elektroniskt styrt pneumatiskhydraulisktventilsystem på en encylindrig förbränningsmotor i en testcell.

Användbarheten av Tekla i Betongkonstruktioner : En jämförelsestudie mellan två modelleringsprogram
This thesis has examined the Tekla Structures modeling software and answered the question of whether it could act as a suitable modeling program for the design department at Bjerking AB in Uppsala. The method used in this work is a case study of a previous project with existing basis to work form. The demarcation of the study was to examine only the usability of the foundations of in situ concrete. The work examined three main areas within the design process. The first was to model the concrete elements then to model the reinforcing and ultimately production of the drawings. Because Autodesk Revit was the existing modeling program in the Department conducted the evaluation as a comparison between the two programs.
Förstår du vad jag menar? - En undersökning om kommunikation med hjälp av bilder mellan användare och systemutvecklare.
Ibland kan det förkomma problem mellan utvecklare och kund/användare då de tar
fram kraven till ett nytt system. En anledning till detta kan vara att
utvecklingsgruppen och användargruppen inte har samma kunskaper och
erfarenheter och talar då inte "samma språk". En lösning till detta problem kan
vara att ta hjälp av en mockup. En mockup är en fysisk och/eller interaktiv
modell av ett gränssnitt. I detta arbete har vi, med hjälp av intervjuer och
observationer, undersökt om detta hjälpmedel underlättar kommunikationen i
verkligheten..
Att mäta bibliotek: en studie av två biblioteks verksamhetsberättelser.
During the late twentieth century, political and societal changes gave rise to an increased interest in performance evaluation in public organizations. This development also affected libraries in the public sector. The main concern for this master thesis is performance measurement in libraries. In this study two different types of libraries are investigated, one public and the other academic. My aim is to find out if and how performance measurement appears in the libraries annual activity reports.
