Reporting an Experience on Design and Implementation of e-Health Systems on Azure Cloud
Electronic Health (e-Health) technology has brought the world with
significant transformation from traditional paper-based medical practice to
Information and Communication Technologies (ICT)-based systems for automatic
management (storage, processing, and archiving) of information. Traditionally
e-Health systems have been designed to operate within stovepipes on dedicated
networks, physical computers, and locally managed software platforms that make
it susceptible to many serious limitations including: 1) lack of on-demand
scalability during critical situations; 2) high administrative overheads and
costs; and 3) in-efficient resource utilization and energy consumption due to
lack of automation. In this paper, we present an approach to migrate the ICT
systems in the e-Health sector from traditional in-house Client/Server (C/S)
architecture to the virtualised cloud computing environment. To this end, we
developed two cloud-based e-Health applications (Medical Practice Management
System and Telemedicine Practice System) for demonstrating how cloud services
can be leveraged for developing and deploying such applications. The Windows
Azure cloud computing platform is selected as an example public cloud platform
for our study. We conducted several performance evaluation experiments to
understand the Quality Service (QoS) tradeoffs of our applications under
variable workload on Azure.Comment: Submitted to third IEEE International Conference on Cloud and Green

Mobile support in CSCW applications and groupware development frameworks
Computer Supported Cooperative Work (CSCW) is an established subset of the field of Human Computer Interaction that deals with the how people use computing technology to enhance group interaction and collaboration. Mobile CSCW has emerged as a result of the progression from personal desktop computing to the mobile device platforms that are ubiquitous today.
CSCW aims to not only connect people and facilitate communication through using computers; it aims to provide conceptual models coupled with technology to manage, mediate, and assist collaborative processes. Mobile CSCW research looks to fulfil these aims through the adoption of mobile technology and consideration for the mobile user. Facilitating collaboration using mobile devices brings new challenges. Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users. This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices
Overview of a media convergence centre (MC2)
Organizational alliances are rapidly being formed as a means for effective cooperation with a common goal within a targeted value chain. The combination of such communication, coordination and cooperation leads to new organisational forms and scenarios within the Digital Ecosystem space that require technological support. Convergence refers to the move towards the use of a single united interaction medium and media. Such a solution enables telecommunications services that are concurrently coupled with enterprise and internet data. Due to the versatile nature of today's extended enterprise, a flexible, feature-rich, adaptive and widely accessible converged solution is required.This paper proposes a Media Convergence Centre (MC:) solution that allows users to participate in a converged multimedia collaboration network using a variety of interaction devices in an easy and convenient manner
Development of an advanced web application for managing videoconference
El objetivo del proyecto es realizar un cliente para videoconferencias de alta
definición basado en Web. Se ha utilizado SIP como protocolo de señalización
(establecimiento, finalizaciĂłn) de videoconferencias, para la gestiĂłn la lista de
los contactos, la presencia, y la negociaciĂłn de las capacidades multimedia.Existen numerosas aplicaciones que ofrecen al usuario la posibilidad de
realizar videoconferencias en alta definiciĂłn sobre Internet. Estas aplicaciones
centran sus esfuerzos en la transmisiĂłn de contenido de alta calidad sobre
Internet, pero dejan sin resolver la gestiĂłn del establecimiento, finalizaciĂłn de
llamadas, aceptaciĂłn, rechazo de invitaciones, suscripciĂłn y recepciĂłn de
notificaciones del servicio de presencia (apariciĂłn de usuarios, cambios de
estado, etc).
El objetivo del proyecto es realizar un cliente para videoconferencias de alta
definición basado en Web. Se ha utilizado SIP como protocolo de señalización
(establecimiento, finalizaciĂłn) de videoconferencias, para la gestiĂłn la lista de
los contactos, la presencia, y la negociaciĂłn de las capacidades multimedia
La aplicaciĂłn desarrollada permite que, un usuario a partir de una web, sea
capaz de ver todos los usuarios conectados al servicio, conocer sus
caracterĂsticas y poder establecer videoconferencias de alta calidad, utilizando
el entorno de videoconferencia negociado (por ejemplo dvts, ultragrid).
La aplicaciĂłn actĂşa como un gateway HTTP-SIP, traduciendo las peticiones
SIP a peticiones HTTP y viceversa. Las peticiones HTTP son enviadas hacia
el cliente para que la trate y realice los cambios necesarios en la interfaz web y
en su modelo de datos. La interfaz de web del usuario se ha desarrollado con
Google Web Toolkit, un toolkit de Google para el desarrollo de aplicaciones
AJAX en lenguaje de programaciĂłn Java.
El servidor se comunica con tres mĂłdulos. Con el mundo SIP para la
señalización de videoconferencia, con el agente de presencia para gestionar la
lista y con el cliente AJAX para comunicarse con los usuarios de la aplicaciĂłn.
El proyecto explica las fases de definición de requerimientos, diseño y
arquitectura de la aplicaciĂłn. Expone el estado del arte de las tecnologĂas y
comenta algunos detalles de la implementaciĂłn, finalizando con una
planificaciĂłn temporal y unos resultados finales del proyecto
Towards the definition of a quality model for mail servers
The paper presents an approach for building a Mail Server Quality
Model, based on the ISO/IEC software quality standard. We start by defining
the mail system domain to be used as general framework and the relevant
technologies involved. Then a general overview of the ISO/IEC standard is
given. The basic steps, the relevant considerations and criteria used to
select the appropriated subcharacteristics and quality attributes are also
presented. The selected attributes are categorized under the six ISO/IEC
quality characteristics conforming the model. Finally some case studies
requirements and two commercial mail server tools are used to evaluate the
model.Postprint (published version

On the benefits of speech and touch interaction with communication services for mobility impaired users
Although technology for communication has evolved tremendously over the past decades, mobility impaired individuals still face many difficulties interacting with communication services, either due to HCI issues or intrinsic design problems with the services. In this paper we present the results of a usability study, conducted with a group of five mobility impaired users, comprising paraplegic and quadriplegic individuals. The study participants carried out a set of tasks with a multimodal (speech, touch, gesture, keyboard and mouse) and multiplatform (mobile, desktop) prototype, offering an integrated access to communication and entertainment services, such as email, agenda, conferencing and social media. The prototype was designed to take into account the requirements captured from these users, with the objective of evaluating if the use of multimodal interfaces for communication and social media services, could improve the interaction with such services. Our study revealed that a multimodal prototype system, offering natural interaction modalities, especially supporting speech and touch, can in fact improve access to the presented services, contributing to a better social inclusion of mobility impaired individuals.info:eu-repo/semantics/acceptedVersio
Converged voice access to data (CVAD)
The rapid growth of the Internet and widespread use of mobile computing and telephony has resulted in a broad range of ways to communicate and access information. Data and telecommunications convergence promises a wide range of possible solutions that will increase productivity, reduce costs, and provide new opportunities and revenues for enterprises. However, such converged telecommunications and data services have been largely isolated to static environments where fixed Personal Computers (PC) and an Internet connection are used in conjunction with various software tools to simulate a pseudo converged session. Generally, data presented on the internet and in enterprise applications is not available on voice networks and vice-versa. Due to the versatile nature of today's enterprise, a feature-rich, flexible, adaptive and widely accessible convergence solution is required. This paper presents an Interactive Voice Response (IVR) driven approach that uses Converged Voice Access to Data (CVAD) services. The CVAD solution offers enhanced service effectiveness, flexibility and convenience for professionals on the move
