I detta arbete undersöks effektiviteten hos Androids medföljande metoder för att uppnå beständigt tillstånd. Undersökningen baseras på ett egenutvecklat verktyg för att mäta de olika metodernas effektivitet, med avseende på tid för att spara ner och läsa in tillståndet samt hur mycket utrymme det sparade tillståndet tar upp i sekundärminnet. Resultaten från undersökningen visar att de olika metoderna presterar olika bra beroende på tillståndets storlek samt om tillståndet mestadels består av text eller av nummer. Den metod som generellt är mest effektiv är Javas Serializable. Framtida undersökningar skulle kunna komplettera den genomförda undersökning genom att också utvärdera effektiviteten hos metoder som tillhandhålls via externa bibliotek..

The Swedish market for unsecured loans has frequently been attacked by media and government officials. Some actors have been accused of exploiting customers and charging inappropriately high interest rates. Despite the public interest very little academic work has been published on the topic. Therefore it is our purpose to investigate why the prices can differ so much between the different actors. Further, we also aim to conduct a market overview as a secondary purpose which will help us in reaching our primary purpose.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

This bachelor thesis aims to analyse the Swedish mortgage market and investigate whether it is in a current price bubble or not. Comparisons have been made with Denmark, a country with a market similar to Sweden?s, and where the mortgage market faced a price bubble that crashed in 2008. The housing market in Stockholm has been analysed as a separate market, as it differs from Sweden as a whole in prices and underlying factors to increased prices. The conclusion of this thesis is that not Sweden, nor Stockholm, is currently in a price bubble at the mortgage market.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system. Based on documentation obtained through interviews a demo system was created based on Bluetooth Low Energy (BLE) communication between an embedded system and an Android device.This report intends to describe the tools and methods used in the design of the demo system and the result of an analysis of the BLE communication.Bluetooth Low Energy is an exciting protocol with wide applicability within the industrial field. This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

Syftet med detta examensarbete var att skapa ett serverprogram i en enkortsdator som arbetar i realtid för att kunna hjälpa människor att köra mer ekonomiskt och miljövänligt i deras vardag.Detta var ett av målen ställda av produktbeställaren Ziggy Creative Colony. Ett mer långsiktigt mål från beställaren är att datorn skall installeras i en bil och kopplas till bilens on-board diagnostic-II (OBD-II)-uttag. Datorn ska sedan, via OBD-II, kunna samla information som till exempel hastighet, acceleration och bränsleflöde från bilens engine control unit (ECU). Serverprogrammet ska bearbeta denna information som sedan kommuniceras och visualiseras till bilföraren via en native mobilapplikation.Serverprogrammet byggdes i en linuxbaserad dator: Raspberry Pi och döptes av oss till Car-Pi. Car-Pi designades enligt arkitekturmönstret Model-View-Controller (MVC) som gör det lätt att underhålla, vidare-utveckla och implementera programmet av produktägaren, Ziggy Creative Colony, i framtiden.

This paper is concerned with surveying the possibilities of implementing a futures market based on the valuation of non-commercial real estate in Sweden. We base our survey on a theoretical speculation of how such a market would operate and what instrument would best suit the marketplace. After reaching our solution we survey key experts to receive their feedback on our suggested solution. Their feedback includes, who are potential operators on this market and their motives, possible effects of such a market on the real estate market and other aspects of society..

På senare tid har smarta mobila enheter fått en allt större roll i vardagen och det finns en uppsjö av applikationer till dessa. Den som är uppmärksam kan upptäcka att prestandan och användarupplevelsen kan variera kraftigt mellan olika applikationer. Prestandaoptimering är en viktig del i utvecklingsprocessen för mobila applikationer eftersom mobila enheter ofta har betydligt mer begränsade resurser jämfört med till exempel persondatorer. Eftersom prestanda är komplext med många faktorer som spelar in kan man använda sig av verktyg för att underlätta optimeringsarbetet. För att hitta de mest lämpliga verktygen för prestandaoptimering av Android-applikationer har en utvärdering av en delmängd verktyg som finns på marknaden utförts.

Many companies choose to position themselves in New York. The city is one of the main cities when it comes to advertising. The competition is strong and for new companies, it is hard to survive on the market.In our thesis we have investigated how Swedish people, who open new advertising agencies in New York, should market themselves to be successful on the market in New York.To gain as much information as possible about this subject, we traveled to New York and interviewed three advertising agencies, who were started by Swedes, and also the Consulate General of Sweden, and Swedish Trade Council.Our investigation resulted in that the best way to be successful on the American market is to differentiate your work from what the market has to offer. By doing this potential customers may find your work interesting and thereby chose to work with your company..

Detta examensarbete utfördes hos företaget Syntronic i mjärdevi. Uppgiften de ville ha utförd var en undersökning och implementation av ny funktionalitet i en redan existerande android applikation som de har utvecklat. Uppgiften i denna applikation var att undersöka möjligheterna till IP-telefoni, eller VOIP som det kallas, så att de kunde ringa varandra via applikationen genom datanätet istället för det ordinära nätet, samt att implementera detta.Detta examensarbete utfördes hos företaget Syntronic i mjärdevi.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.
