  • new designs of a two phase e core switched reluctance machine by optimizing the magnetic structure for a specific Application Concept design and analysis
    IEEE Transactions on Industry Applications, 2009
    Co-Authors: R Krishnan
    Abstract:

    Three new magnetic structures for an E-core switched reluctance machine (SRM) comprising two segmented stator cores or a monolithic stator core are proposed for good manufacturability, mechanically robustness, ease of assembly, and electromagnetic-performance improvement. The E-core stator has four small poles with phase windings and two or four large poles (hereinafter referred to as common poles) in between. The common poles do not have copper windings or permanent magnets. The common poles are shared by both phases for positive-torque generation during the entire operation. The air gap around the common pole has constant and minimum reluctance, irrespective of rotor position, by its unique design, and the two small stator poles experience variable reluctance with respect to rotor position. The segmented stator can be constructed with two independent and physically separate E-shaped cores with L- or I-shaped yokes so that the straight back iron in the stator rather than the curved back iron is suitable for assembly with other parts like end bells or brackets. The monolithic stator also has an L-shaped yoke for the same reason, and the new E-core SRMs are designed by means of pole-arc optimization. The novel E-core SRMs are compared to a conventional two-phase SRM. The comparison includes cost savings, torque, copper and core losses, efficiency, and radial force in order to validate the distinct features of the E-core SRMs. For experimental verification, laboratory testing of a segmented E-core SRM is conducted, and the simulated and measured phase currents and voltages correlate well.

  • User-centered development of a smart phone mobile Application delivering personalized real-time advice on sun protection
    Translational Behavioral Medicine, 2013
    Co-Authors: David B Buller, Marianne Berwick, James Shane, Ilima Kane, Kathleen Lantz, Mary Klein Buller
    Abstract:

    Smart phones are changing health communication for Americans. User-centered production of a mobile Application for sun protection is reported. Focus groups ( n  = 16 adults) provided input on the mobile Application Concept. Four rounds of usability testing were conducted with 22 adults to develop the interface. An iterative programming procedure moved from a specification document to the final mobile Application, named Solar Cell. Adults desired a variety of sun protection advice, identified few barriers to use and were willing to input personal data. The Solar Cell prototype was improved from round 1 (seven of 12 tasks completed) to round 2 (11 of 12 task completed) of usability testing and was interoperable across handsets and networks. The fully produced version was revised during testing. Adults rated Solar Cell as highly user friendly (mean = 5.06). The user-centered process produced a mobile Application that should help many adults manage sun safety.

  • an enhanced device transparent real time teleconsultation environment for radiologists
    IEEE Journal of Biomedical and Health Informatics, 2019
    Co-Authors: Christos Andrikos, Georgios Rassias, Panayiotis Tsanakas, Ilias Maglogiannis
    Abstract:

    This paper describes a novel web-based platform promoting real-time advanced teleconsultation services on medical imaging. Principles of heterogeneous workflow management systems and state-of-the-art technologies such as the microservices architectural pattern, peer-to-peer networking, and the single-page Application Concept are combined to build a scalable and extensible platform to aid collaboration among geographically distributed healthcare professionals. The real-time communication capabilities are based on the webRTC protocol to enable direct communication among clients. This paper discusses the Conceptual and technical details of the system, emphasizing on its innovative elements.

  • a dicom based collaborative platform for real time medical teleconsultation on medical images
    Advances in Experimental Medicine and Biology, 2017
    Co-Authors: Ilias Maglogiannis, Christos Andrikos, Georgios Rassias, Panayiotis Tsanakas
    Abstract:

    The paper deals with the design of a Web-based platform for real-time medical teleconsultation on medical images. The proposed platform combines the principles of heterogeneous Workflow Management Systems (WfMSs), the peer-to-peer networking architecture and the SPA (Single-Page Application) Concept, to facilitate medical collaboration among healthcare professionals geographically distributed. The presented work leverages state-of-the-art features of the web to support peer-to-peer communication using the WebRTC (Web Real Time Communication) protocol and client-side data processing for creating an integrated collaboration environment. The paper discusses the technical details of implementation and presents the operation of the platform in practice along with some initial results.
