These devices are mainly used for content consumption. However, limited resources available on these devices, as well as always connected internet accessibility makes these devices ideal platforms for cloud computing. This project is an attempt at creating personal media cloud player app for Android smart phone devices. The project uses off the shelf hardware components for private cloud implementation and Java programming over Android to provide full featured media cloud platform. This private media cloud enables users to: Store media files (images/audio/video etc) in the cloud Access the media files from their Android device Additionally, the project aims at providing following features: File browsing Audio streaming (MP3) Video streaming (MP4) v Images (JPEG/PNG) e-radio/ Photo Slide Show The project aims at developing an application that can be used by any Android (version 2.2 and higher) smartphone to implement above mentioned media functionality. , Committee Chair Du Zhang, Ph.D. ______________________ Date vi DEDICATION To my family vii ACKNOWLEDGEMENTS I would like to thank my project advisor Dr. Du Zhang for taking time and giving me guidance through the project. I would also like to thank all the professors who taught me during my masters’ course work.

Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them.. A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access User of the cloud only care about the service or information to high-speed Internet and a weak economy, have accelerated interest they are accessing – be it from their PCs, mobile devices, or in cloud computing. anything else connected to the Internet – not about the In this paper we are also going to discuss the advantages, underlying details of how the cloud works.

  • Current Technologies for Behavioral Healthcare Clinical Practice 2
    Current Technologies for Behavioral Healthcare Clinical Practice 2 John S. Luo Introduction In today’s electronic era, the thought of using only paper in clinical practice is not very high on the behavioral healthcare practitioner’s list of ways to be efficient and modern. However, paper has its use for taking notes during sessions as it lends itself more naturally to maintaining eye contact and has less distraction without the clicking noise of the key- board. Computers today offer many compelling reasons to be utilized in the office setting with easier access to information, transmission of data, and storage. For many practitio- ners, computer use has primarily been focused on electronic communication, marketing with a web site, or creation of documents with office productivity suites. This chapter reviews some of the computer hardware and software that will enhance clinical practice in this digital age. Hardware Some would argue that the age-old issue of Mac vs. PC still exists. Nowadays, it is a matter of preference to determine which operating system rules the office. In the past, Mac operat- ing system computers were considered for personal and educational use and for use in creative professions, whereas PCs were the dominant force in traditional businesses. With increasing Apple market share in all types of business, especially as the ease of use and increased availability of relevant Mac operating system (OS) software for business has developed over the years, trying to decide between Windows vs. Mac OS is a moot issue. In fact, as more applications are being developed for web delivery such as electronic medi- cal records, even a computer based on Linux OS has its place in the behavioral healthcare office.

Tanjung No.1 Blitar [email protected] 2 Program Studi Sistem Informasi, Fakultas Ilmu Komputer, Universitas Nahdlatul Ulama Sidoarjo Jln. Mongonsidi Kav. DPR Sidoklumpuk Sidoarjo [email protected] Abstrak Cloud Storage memberikan beberapa kemudahan dalam sentralisasi penyimpanan data. Cloud Storage merupakan media penyimpanan yang di dalam pengaksesannya memerlukan jaringan internet. File dan data disimpan di komputer dimana user harus membuat akun Cloud Storage terlebih dahulu. Sebagai langkah kemudahan dalam mengakses data dalam sebuah instansi maka dibutuhkan strategi sentralisasi data yang dapat diakses dan berbagi file atau data bersama dengan biaya lebih murah. Private Cloud Storage bisa dicapai dengan mengimplementasikan Framework ownCloud berbasis Open Source. Penelitian ini bertujuan untuk mengembangkan teknologi penyimpanan data secara terpusat yang memungkinkan user bisa berbagi file atau data bersama. Kata Kunci: Cloud Storage, ownCloud, Private Cloud Storage, Open Source 1. PENDAHULUAN Perkembangan teknologi saat ini mengalami perubahan yang sangat pesat. Hal ini mempengaruhi perkembangan media penyimpanan pada komputer dari masa ke masa. Salah satu jenis berkembangannya adalah media penyimpanan berbasis cloud (awan). Cloud (awan) adalah metafora dari internet, sebagaimana awan yang sering digambarkan di diagram jaringan komputer. Menurut makalah tahun 2008 yang dipublikasikan IEEE Internet Computing, Cloud Computing merupakan suatu paradigma dimana informasi secara permanen tersimpan di server intenet dan tersimpan secara sementara di computer pengguna (client) termasuk di dalamnya desktop, komputer, tablet, notebook dan lain- lain.

    Volume 5, Issue 10, October-2015 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com Implementation of an Efficient Platform to Use Android as a Server Mukta Dutonde*, Prof. S. B. Jadhav Computer Engineering Department, Dr. VBKCOE, Malkapur, Maharashtra, India Abstract: Nowadays the number of smartphone users are growing rapidly. But the users expects that the smartphones must have PC like functionality, memory, batteries and hardware resources such as CPU are limited. Many researches have proposed conceptual architecture to use server resources in the cloud for mobile devices to solve this resource problem. The system proposed the conceptual architecture of implementation of an efficient platform to use android as a server which enables multiple users to use Android application on cloud server via network. Though Android is designed for physical smartphone , it has an useful feature to construct a server platform. Android is an open source mobile OS and runs on an X86 CPU. In this paper we discussed the direction to take into reality the multitenant architecture for an Android server platform. Keywords—multitenant, server platform, cloud server, Android I. INTRODUCTION The number of Smartphone users and mobile application are growing rapidly. According to a recent report, 45 million people in the U.S. own Smartphone’s and 234 million people subscribe to the mobile phone application stores[1].There are several mobile Operating Systems (OSs), such as symbian, iOS, Android, and Windows Mobile. Because thousands of application developers construct many kinds of application for these platforms, users can easily enjoy their individual Smartphone lifestyle.
