  • Evaluating alternative DaaS solutions in private and public OpenStack Clouds
    Software: Practice and Experience, 2017
    Co-Authors: Antonio Celesti, Davide Mulfari, Maria Fazio, Antonio Puliafito, Massimo Villari
    Abstract:

    Summary Nowadays, Remote Desktop technologies are widely used to control Remote computers. In this context, more and more Desktop as a Service (DaaS) solutions that allow users to directly control Virtual Machines through HTML5 web applications are emerging. However, currently, DaaS is at an early stage because several issues have to be addressed. In this paper, we aim to provide software architects a 360-degree study on the major web-based Remote Desktop Client systems for the development of next generation DaaS solutions in both OpenStack-based private and public Clouds. In particular, we compare and test different native and customized web-based Remote Desktop solutions, specifically focusing on audio and video redirection performances in both Cloud environments. Exhaustive experiments highlight, from an objective point of view, the behavior of different DaaS solutions, providing useful hints to software architects and developers.

  • ISCC - Improving Desktop as a Service in OpenStack
    2016 IEEE Symposium on Computers and Communication (ISCC), 2016
    Co-Authors: Antonio Celesti, Davide Mulfari, Massimo Villari, Maria Fazio, Antonio Puliafito
    Abstract:

    OpenStack is one of the major open-source solutions for creating and managing Infrastructure as a Service (IaaS) cloud providers. In this paper, we explore how the Horizon dashboard allows us to access virtual machines via a web-based Remote Desktop Client. Besides the default Remote Desktop Clients (based on the noVNC software), we propose to integrate in the OpenStack dashboard other alternative solutions testing both audio and video redirection feature. We consider different protocols including Virtual Network Computing (VNC) and Remote Desktop Protocol (RDP), while our experiments aim to evaluate which the best solution currently available on the market is, also providing indications to developers on how to extend the OpenStack dashboard in order to provide the best user experience from an objective point of view.

  • NCCA - Using Virtualization and noVNC to Support Assistive Technology in Cloud Computing
    2014 IEEE 3rd Symposium on Network Cloud Computing and Applications (ncca 2014), 2014
    Co-Authors: Davide Mulfari, Antonio Celesti, Massimo Villari, Antonio Puliafito
    Abstract:

    In this paper, we focus on how the virtualization technology can support the usage of Assistive Technology (AT) in cloud computing. AT provides software tools to people with disabilities. Unfortunately, these pieces of software are not easy to configure when a disabled user needs to occasionally use a shared computer, e.g., in an internet point, in a library, in a campus, and so on. The proposed solution allows users to access Remote Virtual Machines (VMs) through an HTML5 web interface. These virtual environments meet the user's personal demand: they support both traditional Desktop applications and customized AT tools. In this way, people with disabilities can use any networked computer with a web browser to manage their personal working environments. Nevertheless, achieving such a goal in a cloud computing environment is not trivial at all, because existing Remote Desktop Client viewer applications have not been designed to support the interaction with AT software running on VMs. To achieve such an objective, we propose an open source cloud-based system including no VNC as HTML5 Remote Desktop proxy/Client web application, Virtual Network Computing (VNC) as open source technology to access a Remote VM, Oracle Virtual Box as hypervisor, and CLEVER as Virtual Infrastructure Manager (VIM) middleware.

  • Intelligent Control Strategy for Ceramic Metal Halide Lamps
    DEStech Transactions on Materials Science and Engineering, 2017
    Co-Authors: Y Pan
    Abstract:

    An intelligent control strategy for driving a 35w Ceramic Metal Halide (CMH) lamp is built. By integrating the microcontroller STM32F103 with the digital potentiometer X9313 in the circuit, we are able turn the lamp on and off flexibly. The lamp power can be altered automatically according to the environment, since it is designed to be linearly dependent on the resistance of X9313. The energy conversion efficiency of the driving circuit can be larger than 88%. A Remote Desktop Client on the Android is developed for the purpose of wireless and convenient control. The proposed model will useful for designing high performance small-wattage CMH lamps.

  • Digital control of low-frequency, small-wattage, high-intensity discharge lamps:
    Lighting Research & Technology, 2016
    Co-Authors: Y Pan, Chun-zuo Huang, Jie Lin, Jincan Chen
    Abstract:

    A digital circuit for driving a low-frequency, small-wattage, high-intensity discharge lamp is proposed. By combining a digital potentiometer X9313 and a microcontroller STM32F103, the lamp can be turned on and off automatically according to the operating condition. The lamp power can be altered flexibly based on the needed luminance because it is designed to be a linear function of the resistance of the potentiometer X9313. The lighting system has an electrical efficiency of 88% and can save more than 20% of energy, compared with a traditional lamp. A Remote Desktop Client on Android is developed for the purpose of wireless and convenient control. The proposed model will provide important information for designing high-performance, low-frequency, small-wattage, high-intensity discharge lamps.
