Title: Multi-platform Multiplayer RPG Game A multi-platform game, which would be able to run on various devices with Windows 8.1 and Windows Phone 8.1 systems, was created in this work. It was supposed to be a universal game client executable on desktop PCs, notebooks, tablets or mobile phones. The game was supposed to be role-playing game (RPG) with focus on turn-based action combat. In this work, a 3D scene renderer was written which supports rendering simple scenes with objects and animated characters. A cross-device communication library based on bluetooth technology was implemented in this project as well. This communication library allows two game clients running on two different types of devices to communicate with each other. Then a server-client communication library was created. This library was then used to implement a game server which offers online gaming feature.

Today, there are a handful of different platforms for mobile phones. Writing an application natively for each mobile operating system is time consuming and expensive. This situation has created a need for using cross-platform frameworks, that allow programmers to create an application once and run it on all platforms. The problem is that it is not certain whether cross-platform apps can fully replace native ones, or if by using cross-platform tools some desired qualities are lost. Investigating this issue would allow to find out which one of these two application development methods is better, or in which situation it is better to choose one over the other. Such knowledge would allow to decrease development time and costs. Companies that create mobile applications on a daily basis have expertise in this area. Thus, thirteen interviews were done with thirteen distinct businesses in order to research this problem. The results showed that native development produces higher quality applications, but there are some situations where it might be better to use cross-platform frameworks.

Mobiltelefoner innehåller idag en stor mängd information som är av stort forensiskt intresse. Att skydda informationen i sin telefon är en självklarhet för många och utvecklarna av de mobila operativsystemen lägger nu större vikt på säkerhet och skydd av information. Kryptering är idag standard i de flesta mobiltelefoner och det leder till problem vid utvinning. Arbetet tar upp och jämför hur kryptering hanteras av iOS, Android och Windows Phone och vilka tillvägagångssätt som finns vid utvinning av data genom att kringgå skärmlåsen som krävs för att krypteringen ska fungera. Arbetet ger även en inblick på molnlagring i och med att det blir allt vanligare och kan komma att bli mer relevant för forensiker eftersom telefonerna blir allt svårare att utvinna data ifrån. Dessutom ges en liten inblick på forensiska verktyg som finns idag, vilka brister de har och vad som är oklart hos dem.  Frågeställningarna har besvarats genom att en grundläggande litteraturstudie genomförts för att få den bakgrundsfakta som krävs. Därefter gjordes det experiment för att visa på brister i de forensiska verktygen. Avslutningsvis svarade två it-forensiker från polisen på intervjufrågor via mail, det gjordes för att lyfta fram problematiken och visa på hur situationen ser ut i arbetslivet idag.  Arbetets resultat visar på att alla operativsystem ger, beroende på hur användaren har anpassat telefonen, möjlighet till fullt skydd mot utvinning. Och därmed klarar de forensiska verktygen som finns idag inte av att utvinna någon relevant information ifrån de senaste mobiltelefonerna. Som forensiker borde man utnyttja att molnlagring börjat användas mer och mer, då det där kan finns mycket bra information. Slutsatser som kan dras efter arbetet är att det behövs nya metoder för att utvinna data ifrån mobiltelefoner då de metoder som tidigare använts inte är kompatibla med de senaste telefonerna på grund utav de krypteringsfunktioner som används. Det finns metoder som kan fungera, men dessa metoder fungerar bara med rätt förutsättningar, vilket gör att det inte är en lösning som man alltid kan applicera. Forensiker borde även utforska möjligheten att få fram information ifrån molnlagringstjänster ifall data på telefonen är oåtkomlig för alla utom ägaren. Arbetet syftar inte till att ta fram nya metoder för utvinning eller arbetssätt inom det stora området forensik, utan kartlägger problemområdet inom mobilforensik och ger förslag på och diskuterar möjliga lösningar.

A problem with having a fast and wide production of different platforms for mobile devices is that you can’t code for one and deploy on all devices at the same time. This thesis is focused on cross-plat1form development environments for smartphones and mainly to see what options there are on the market. This report will investigate how well a cross-compiler solution compares to hybrid cross-platform development. To do this we took a closer look at their architecture and then compared this with the results from different tests made. All the tests were made on the same smartphone to ensure fairness between them. All the tests strive to be as equal as possible even though the languages might differ from each other. The tested frameworks were PhoneGap, Qt, Unity3D and GameMaker. The different tests were about performance, power consumption, difficulty in accessing web browsers to perform HTML parsing and lastly to see if the platforms can access different native APIs such as the camera and accelerometer. The previously mentioned topics were compared between all the frameworks. We also compared the documentation found on their webpage to figure out which is the easiest to get started on.

It was supposed to be a universal game client executable on desktop PCs, notebooks, tablets or mobile phones. The game was supposed to be role-playing game (RPG) with focus on turn-based action combat. In this work, a 3D game engine was written which supports rendering simple scenes with objects and animated characters. The engine was developed using DirectX. The engine was written in .NET C# using SharpDX library. A cross-device communication framework based on bluetooth technology was implemented in this project as well. This communication framework allows two game clients running on two different devices to communicate with each other.

The client part of the system is comprised of a library intended for developers of games, which encapsulates the API needed to access the backend on the Internet, and a graphic frontend intended for end users. The server part, which contains most of the application logic, has REST interface. The applications architecture allows future development in terms of new functionality and expansion on more client platforms.

This thesis deals with developing applications on Windows Phone 7. The application focuses on two main target groups; cyclists and individuals who are confined to wheelchairs. Application offers the possibility of navigating around the city and over difficult terrain, and is divided into two parts - the client side application, and server side application. Development of the server side application will be analyzed in the thesis Development of map application for tracking in cloud - Server side on Windows Azure, by Vojtech Ruzicka. The primary objective of this thesis is to offer new solutions for development on Windows Phone 7, with attention being given to the communication between client and server. The second objective is to provide the public with the free application, which will help cyclists and handicapped individuals to navigate through cities around the world. The primary goal of this thesis will be achieved by identifying any problems that may arise during development, whereby a simplified description of the problem will be formed and a solution provided. Realization of the second goal will be in the use of application by the public, by providing them with an efficient means of increasing their mobility throughout their surroundings.
