Cross-Platform Diagnostic Tool Självständigt arbete på avancerad nivå Independent degree project second cycle M.Sc. Thesis Within Computer Engineering C, course, 30 points Cross-Platform Diagnostic Tool Ali Zamani Cross-platform Diagnostic Tool Abstract Ali Zamani 2013-07-11 Abstract In Automotive Industries, to be confident regarding the success of a planned operation, performing accurate methods in order to detect abnormal operating conditions, known as faults, is crucial. An effective method for diagnosis and fault recognition ensures the safety of the operation, reduces manufacturing cost and any other potential impacts. In addition, mobile solutions have been widely adopted among automotive manufactures during recent years and they have taken full advantage of mobile strategies. Accordingly, it is necessary for there to be a future-proof plan to control the diagnostic operations in advance. In this thesis, the immediate objective has been to offer a future-proof and user-friendly solution to assist engineers and service technicians in the monitoring, detecting, and diagnosing of faults on Toyota/BT/CESAB branded trucks. A mobile cross-platform framework is used to develop the diagnostic mobile solution which is not only able to be deployed on Android and iOS mobile platforms, but also provides wireless communication between truck machines and mobile devices through Bluetooth and Wi-Fi ad hoc technologies. The diagnostic mobile tool is capable of processing real-time controller area network messages and visualizing the condition of different sensors in a more user-friendly way through rich hybrid and client-side web user interfaces. The experience of evaluating a cross-platform diagnostic tool on different mobile operating systems proved that cross-platform mobile development methodology can be a reliable technique for developing projects that essentially require real-time data processing. In addition, it indicates that Apple iOS offers a better runtime performance than Google Android for the current tool.

  • The Importance of Object-Oriented Programming in This Era of Mobile Application Development
    IOSR Journal of Computer Engineering (IOSR-JCE) e-ISSN: 2278-0661,p-ISSN: 2278-8727, Volume 17, Issue 6, Ver. I (Nov – Dec. 2015), PP 30-40 www.iosrjournals.org The Importance of Object-Oriented Programming in This Era of Mobile Application Development Onu, F.U*, Ikedilo, O.E*, Nwoke, B.O* and Okafor, P* *Department of Computer Science, Ebonyi State University, Abakaliki Abstract: In the past two decades object oriented programming has become the dominant programming OOP paradigm used by application developers. Object oriented programming scales very well, from the most trivial of problems to the most complex tasks. It provides a form of abstraction that resonates with techniques people use to solve problems in their everyday life. Although the fundamental features of what we now call object- oriented programming were invented in the 1960's, object oriented languages really came to the attention of the computing public in the 1980's. Software producers rush to release object oriented versions of their products. Countless books and special issues of academic and trade journals have appeared on the subject. Object- oriented programming is being greeted with even more enthusiasm than we saw heralding earlier revolutionary ideas, such as structured programming". The intent in this publication is to emphasize and explain the importance of object-oriented programming in this era of mobile development, and in doing so to illustrate the following two propositions: OOP is a revolutionary idea, totally unlike anything that has come before in programming, OOP is an evolutionary step, following naturally on the heels of earlier programming techniques.

  • Cross-Platform Mobile Applications with Web Technologies
    International Journal of Computing and Digital Systems ISSN (2210-142X) Int. J. Com. Dig. Sys. 4, No.3 (July-2015) http://dx.doi.org/10.12785/ijcds/040302 Cross-platform Mobile Applications with Web Technologies Christos Bouras1,2, Andreas Papazois2, and Nikolaos Stasinos2 1 Research Unit 6, Computer Technology Institute & Press “Diophantus”, Patras 26504 , Greece 2 Computer Engineering & Informatics Department, University of Patras, Patras 26504, Greece Received 21 Nov. 2014, Revised 19 Jan. 2015, Accepted 7 Mar. 2015, Published 1 July 2015 Abstract: The extended use of smart mobile devices has become an integral part of daily life leading to the expansion of mobile application development. Currently, the majority of mobile applications are native applications that need an initial installation prior to being utilized. In addition, for a given application, a separate software development process could be required for each mobile platform, which subsequently increases dramatically the corresponding effort and cost. With the emergence of HTML5 these issues can be addressed efficiently, since web technologies allow the application development in a cross-platform manner. An important benefit is that users can have easy and immediate access the application without any need for downloading and installation. In this manuscript, we investigate the potentials of mobile application development with web technologies and we present a development framework that we have designed and implemented. This framework utilizes the most important state-of-art web technologies for the support of mobile devices. It can be used for the implementation of mobile web applications and also for the investigation and experimentation on the main features that HTML5 offers for this specific type of devices.

  • Using Jquery Tools in Wordpress
    Using jQuery Tools in WordPress Throughout this book, we've looked at various examples of what is possible to achieve using jQuery Tools. However this has been within the confines of a standalone environment, It's time to have a look at how these tools could be used within a CMS such as WordPress. Over the next few pages, we are going to take a look at how jQuery Tools can be implemented in a CMS, by means of examples based around WordPress. We will focus on the following: • Incorporating jQuery Tools into your plugin or theme • Incorporating a number of tools into WordPress by using plugins, themes or shortcodes, with examples of Overlays, Tabs, and Slideshow • Using one of the original examples from the book, and adapting it for use in WordPress So, in that time honored tradition: "What are we waiting for? Let's get on with it…" The examples that feature in this chapter assume a degree of prior knowledge of using Wordpress and jQuery together. If you would like further information on using both, then it is worth reading Wordpress 3.0 jQuery by Tessa Blakeley Silver, which is available from Packt Publishing. Using jQuery Tools in WordPress Tools you'll need To get started with the demos and examples that feature in this chapter, there are a number of tools you will need. It is assumed that you will have some knowledge of them, or at least a favorite, so we won't go into too much detail. The critical ones you need are the following: • A text editor: There are hundreds available, all with differing capabilities or features.

  • Cross-Platform Mobile Development: an Alternative to Native Mobile Development
    Degree project Cross-Platform Mobile Development: An Alternative to Native Mobile Development Author: Suyesh Amatya Supervisor: Dr. Arianit Kurti Date: 2013-10-29 Course Code: 5DV00E, 30 credits Level: Masters Department of Computer Science Abstract Mobile devices and mobile computing have made tremendous advances and become ubiquitous in the last few years. As a result, the landscape has become seriously fragmented which brings lots of challenges for the mobile development process. Whilst native approach of mobile development still is the predominant way to develop for a particular mobile platform, recently there is shifting towards cross-platform mobile development as well. In this thesis, a survey of the literature has been performed to see the trends in cross- platform mobile development over the last few years. With the result of the survey, it is argued that the w eb-based approach and in particular, hybrid approach , of mobile development serves the best for cross-platform development. Using the hybrid approach, a prototype application has also been developed and built into native application for different platforms. This has helped to get a better insight about the domain of cross-platform mobile development and its main advantage of the unification of the development and testing process. The results of this work indicate that even though cross platform tools are not fully matured they show great potential and reduce the cost associated in developing native mobile applications. Cross-platform mobile development is equally suitable for rapid development of high-fidelity prototypes of the mobile application as well as fairly complex, resource intensive mobile applications on its own right.
