With mobile web browsers holding around eight percent of the global browser market share in terms of usage, web development for these platforms is becoming critically important as usage moves from the desktop towards mobile devices. Recent advances in client side browser technology like HTML5 and WebSockets have allowed web browser applications to approach feature parity with thick client desktop applications. This paper explores the possibility of a real-time online multiplayer game playable from just a mobile device's web browser. It does not focus on gameplay or graphics, rather it focuses on the backend infrastructure needed to support such a game. The framework devised to support this sort of interaction, Marionette, is well suited towards addressing sharing of location-specific, short-lived information between people using their smartphones without the use of any external software or proprietary software packages on the client side. / text

Despite the extensive research being done in inter-organizational systems (IOS) adoption in the industry-to-industry field, there seems to be a lack of similar research being done in the IOS adoption for the university-to-industry context. This study takes up this lack of research and focuses on what factors that affect the adoption of IOS in the university-to-industry context instead of the industry-to-industry one. The purpose of this paper is to find how different factors influence IOS adoption decision in the university-to-industry context from the university’s perspective. The study was conducted with a qualitative approach. Five interviews were conducted with coordinators and researchers from different research units at Linnaeus University. The study found seven inter-relationships among the influential factors and how they affect the IOS adoption decision. A model that describes the relations is presented by the end of the study. The study is conducted in the qualitative nature and the sample size is rather limited. Therefore, the findings of the study cannot be generalized.

With the advent of HTML5 as the new standard, web pages became an alternative to native Android and iPhone applications, what made it possible to reduce time and cost of app development and maintenance processes.This thesis is aimed for finding, analyzing and documenting experience and criteria that have weight in a selection of the technology for development of search apps. To achieve this, were developed and compared three alternative client apps (Web-based HTML5, Android and iOS).The results of the thesis provides recommendations for selection the appropriate alternative for the successful development strategy, overview of the problems which may occur during development process, pros and cons of a plain Web-based solution, a Web-hybrid solution, and native Android/iOS solutions that are evaluated for a search intensive apps.

Image enhancement improves an image appearance by increasing dominance of some features or by decreasing ambiguity between different regions of the image. Image enhancement techniques have been widely used in many applications of image processing where the subjective quality of images is important for human interpretation. In many cases, the images have lack of clarity and have some effects on images due to fog, low light and other daylight effects exist. So, the images which have these scenarios should be enhanced and made clear to recognize the objects clearly. Histogram-based image enhancement technique is mainly based on equalizing the histogram of the image and increasing the dynamic range corresponding to the image. The Histogram equalization algorithm was performed and tested using different images facing the low light, fog images and colour contrast and succeeded in obtaining enhanced images. This technique is implemented by averaging the histogram values as the probability density function. Initially, we have worked with the MATLAB code on Histogram Equalization and made changes to implement an Application Program Interface i.e., API using Xamarin software. The mobile application developed using Xamarin software works efficiently and has less execution time when compared to the application developed in Android Studio. Debugging of the application is successfully done in both Android and IOS versions. The focus of this thesis is to develop a mobile application on Image enhancement using Xamarin on low light, foggy images.

Storing warranty receipts can sometimes be problematic. Receiptscan be lost, bleached and become illegible or in an extreme case, the storage area is destroyed. The company Freck AB offers a service to store these receiptsonline. They also provides a webpage where the user is able to handle their receipts and an iPhone client for easier uploading. Since the smartphones are increasing in market share each year, with different operating systems, it causes a market fragmentation. If Freck AB wants to address more potential customers, the application needs to get ported to more platforms. Currently iOS holds a 15.7% of the market share, and if the application is ported to the AndroidOS platform, 38.4% of the smartphone users will be addressed. This thesis will present a portation of an iOS application to the Android OS platform. It will also discuss basic Android programming together with the Android SDK classes and techniques used. The portation was considered successful and the subgoals were met. The application has been tested on multiple emulators and on one physical device with good results.

The innovation progress for municipalities is currently going slowly. Today most of the communication, decision-making, delegation and service of process are still handled via letter mail or phone calls. Companies and municipalities are starting to comprehend this and see opportunities. With the technology that exists today it is possible to speed up the processes when citizens and municipalities comunicate with each other. By migrating from the old way of applying and filing different matters by letter mail to so-called digital e-services, the citizen can apply, complement and get info on how their matter is going directly on the web. Abou AB works with optimizing information handling for municipalities and has recently made it possible for municipalities to eliminate their tedious way of handling matters by traceable web communication. They have a vision to take this to a new level of easement to the municipalities and their citizens by offering these services in mobile phones as so-called apps. One of these contemplated services is to file error reports. The service will offer the citizen to send in a report with attached meta data such as photo and the location of the regarding matter. This will be done by the mobile phones built in hardware in form of camera and GPS. This master’s thesis will describe the work to develop a prototype for filing an error reports in mobile phones that support Android and iOS operating systems. The goal for this thesis work is to develop this prototype by means of a process tool called Kanban and investigate if the tool fits the situation properly. The situation is that two persons will work in parallel with slightly different projects. Also the quality and usability of the resulting prototype applications is asserted with qualitative evaluations that results in higher awareness of the defects and suggestions on how to reform and improve the application in a usability point of view. The actual implementation work was planned according to a slightly loose Kan- ban paradigm. Kanban is all about improvements along the way and the im- plementation phase is divided into smaller phases with sub goals and recurring process evaluations. Suggestions of improvement regarding the work processes is a result of this. A Kanban board that helps visualize the workflow is used to help team members and project owners to get a good overview of current situa- tions. Several adjustments were made throughout the project and the so-called lead times, the time it takes to complete a task, was shortened in average from the beginning of the project compared to the end of the project. Each phase in the implementation part of the thesis work resulted in different functionalities in the application. A phase was two weeks long and ended with a demo were the new functionality was demonstrated. Prior to each demo session everyone at the company where the thesis work was performed was invited. The participants in these sessions were encouraged to give feedback on what they saw to help increase the quality of the applications. The prototype applications resulted in a more easy accessible service to citizens. By cutting out the process steps that previously needed to been done on a computer the 1application contributes to the possibility of an increased democratization grade for the citizen. The investigation regarding if the Kanban process tool was a suitable aid in the implementation part of the project resulted in that it was suitable for the specific situation. By measuring both lead times and other activities that did not concern the implementation work and plot them in a diagram explained why some weeks did not have as high productivity as others. To assert the awareness and quality of the developed applications in terms of usability a so-called heuristic evaluation was performed. This qualitative eval- uation resulted in a set of usability problems. These problems were all graded into different priority to be solved and some was given suggestions on how to be solved. The main purpose with this evaluation was to find the problems and document them to possible future programmers if the prototype will go into production. The result of this evaluation has increased the usability of the application and consequently the quality.

In the African continent the mobile phones are already contributing theirshare in the development of the continent. Specially in Ethiopia, in onedirection, the users of mobile phones are increasing each year and mostimportantly the small scale farmers who contribute 85% of the country’spopulation are using these devices to trade their surplus products in anefficient manner and better deal thus earn good profit. In anotherdirection, Ethiopia has set up its own Commodity Exchange in 2008 sothat farmers and traders could buy and sell commodities in an efficientand transparent manner. Taking into consideration both of thesedevelopments carried out to encourage smooth trade and modernmarking strategies, this project has a target to come up with mobileapplications for the Android mobile platform and iPhone users in the firstphase of implementation. Accordingly, the app developed will help to getreal time Ethiopia commodity Exchange (ECX) market prices, commodityrelated headlines, weather forecasts and other relevant news. It willcontribute to standardize the way ECX is performing to link up differentparties specially farmers who make up majority of the country’spopulation and support the economy of the country in a great deal withthe traders. Although the mobile app developed does not have an aim tobring in significant change into the existing system at the currentpenetration of Smartphone in the country, it helps to disseminateinformation in standardized manner as in big commodity exchanges andbesides, we believe in the future it will be the convenient and widely usedmeans to reach the traders with necessary information.

The primary purpose of this study is to determine in which technology we have to develop an application depending on the features that we would like to include, in order to deliver the best value for a good price to the customers. Consequently, in this research we have described the capabilities, performance and limitations that we have found while using the different technologies. The empirical part of this study was conducted in the first semester of 2014/2015 at the Linnaeus University in Växjö (Sweden), supported by Softwerk Company. In conclusion, the thesis shows that the user experience with native apps is always better than using the web-based technologies, especially using maps, although the time and effort spent to develop them is higher. Cross-platform solutions can be very useful for simple apps, and also if the developer does not have a lot of time to develop them. The problem with this last kind of applications is that the performance is less than the native ones.
