  • Lively Mashups for Mobile Devices
    Lively Mashups for Mobile Devices Feetu Nyrhinen, Arto Salminen, Tommi Mikkonen Tampere University of Technology Antero Taivalsaari Sun Microsystems Laboratories Outline • Background • Mashups • Mashup Development and Tools • Lively Mashups • Qt as a Mashup Platform • Mashup demos • Experiences • Conclusions Background • Web as the platform • End-user software is moving to the Web. • Typical examples: project management, calendars, document management, instant messaging, social networking, … • Web browser acts as a replacement for the conventional OS. • Mobile devices are becoming web-enabled, but there still are constraints such as smaller screen size, battery consumption, lower CPU speed and network bandwidth. Mashups • Mashup: A web site that combines content from more than one source (multiple web sites) into an integrated experience. • Mashups leverage the power of the Web to support worldwide sharing of content that would not have been easily accessible or reusable before the Web. • In principle, the content to be combined can be anything (text, source code, maps, video, blogs, product reviews, price data, ...) as long as it can be meaningfully combined with other content. • See, e.g., http://woozor.us/ (Weather conditions on Google Map) Mashup Development and Tools • There is a plethora of various tools for the mashup development. • However, general tools are still fairly limited in functionality and many of those are far from finished applications. • Some common trends: • Using the web not only for executing applications but also for developing them. • Visual programming techniques. • The web server is used to host and share mashups. • Direct connections to existing web services. • Mashup development for mobile devices is still a field with big challenges.

  • A Comparative Analysis of Mobile Operating Systems Rina
    International Journal of Computer Sciences and Engineering Open Access Research Paper Vol.-6, Issue-12, Dec 2018 E-ISSN: 2347-2693 A Comparative Analysis of mobile Operating Systems Rina Dept of IT, GGDSD College, Chandigarh ,India *Corresponding Author: [email protected] Available online at: www.ijcseonline.org Accepted: 09/Dec/2018, Published: 31/Dec/2018 Abstract: The paper is based on the review of several research studies carried out on different mobile operating systems. A mobile operating system (or mobile OS) is an operating system for phones, tablets, smart watches, or other mobile devices which acts as an interface between users and mobiles. The use of mobile devices in our life is ever increasing. Nowadays everyone is using mobile phones from a lay man to businessmen to fulfill their basic requirements of life. We cannot even imagine our life without mobile phones. Therefore, it becomes very difficult for the mobile industries to provide best features and easy to use interface to its customer. Due to rapid advancement of the technology, the mobile industry is also continuously growing. The paper attempts to give a comparative study of operating systems used in mobile phones on the basis of their features, user interface and many more factors. Keywords: Mobile Operating system, iOS, Android, Smartphone, Windows. I. INTRUDUCTION concludes research work with future use of mobile technology. Mobile operating system is the interface between user and mobile phones to communicate and it provides many more II. HISTORY features which is essential to run mobile devices. It manages all the resources to be used in an efficient way and provides The term smart phone was first described by the company a user friendly interface to the users.
