With the widespread use of mobile applications in daily life, it has become crucial for enterprise software companies to quickly develop these applications for multiple platforms. Cross-platform mobile application development is one of the most adopted solutions for rapid development. Since most of these solutions do not generate native code for the underlying platform, the artefacts generally do not satisfy the requirements defined at the beginning of the project. This study designed and implemented a native code generation framework called Nativator built as a cloud service. The framework, which is capable of producing native code for iOS and Android platforms using web-based user interfaces, was implemented based on an open source compiler platform called “Roslyn”. Four case studies were performed to analyze the execution performance of the applications built with the proposed framework. The experimental results demonstrated that the execution performance of the applications built with Nativator is comparable with the applications generated via the state-of-the-art mobile application development framework called Xamarin. Because this framework was implemented as a cloud service, it has several advantages over traditional approaches such as access from anywhere, no installation and flexible and more resources from cloud infrastructure.

The clustering has provided data analysis in many contexts of Computer Science. It is widely applied in Ambient Intelligence and Ubiquitous Computing for information processing, with geolocation data prominently. In this paper, we introduce a dynamic fuzzy temporal clustering algorithm (DFTC) to detect stays of users in urban environments based on locations from imprecise sensors. Our approach includes fuzzy evaluation of temporal and probabilistic data providing analysis in real time. As results, we have developed a mobile application which integrates the DFTC and detects satisfactorily user stays related to urban commerces from a real environment.

This research introduces architecture of new approach of distributing XML data files between different mobile application servers. The main objective and goal of this study is to transmit XML data files between different Mobile Application Server (MAS) using internet cloud infrastructure in a secured manner coupled with reliability and quality of communication. Taking into consideration that the system architecture attribute is to be independent, scalable, and flexible of using cloud computing. Furthermore, this architecture is designed to minimize the risk of any alteration, data loss, data abuse, and data misuse of XML critical business data information. As cloud computing, using existing cloud network infrastructure to get advantage of the scalability, operational efficiency, and control of data flow are a big consideration in this architecture. A test has been made to measure the performance of the Real-time Interactive Data Exchange system (RIDX), one by using standard TCP protocol, and one by using RIDX UDP protocol. As a result, RIDX architecture performance showed good results; conversely the study showed that using RIDX UDP protocol as a transport protocol gives better performance than standard TCP. Moreover, using RIDX UDP transport protocol assures the reliability and lossless of data transmission to all nodes.
