An Application of Multimedia Services on Transportation: The Use of the World Wide Web (WWW)
INTRODUCTION
In recent years, there is an ever-increasing demand and interest in the use of multimedia
technology and applications in industry, government and academia. Multimedia is often
seen by researchers as the next step forward in interfacing science, technology and
community. Yet, the terminology of multimedia bears several meanings. It may refer to
Compact Disc (CD), moving pictures or video-conferencing. The multimedia technology
referred in this paper is the World Wide Web (WWW) hypertext publishing information
system which was developed by and started at the European Laboratory for Particle
Physics (CERN) in Geneva, Switzerland. Since the introduction of WWW, its use has
increased dramatically within a couple of years in a widely diverse community including
government departments, university and research establishments, and commercial
organisations. It has significant influence to our communities and our daily lives. Yet, in
most cases, applications of WWW services are largely restricted to electronic library
referencelcatalogue search facilities, electronic mail systems, electronic conference and
discussion systems, electronic news and publishing agents, and remote access to computing
resources on the Internet.
The primary objective of this paper is to exploit the potential of this multimedia technology
as a simple, easy-to-use and effective means of telematics application in transportation
research. It is hoped that initiatives are highlighted via this study and hence encourage
participations and collaborations from different sectors of industries.
In this paper, a brief history of WWW is given in section (2). An overview of the technical
aspects in providing a WWW service is presented in section (3) in terms of computer
hardware requirements, software installation, network connections, application
maintenance and administration, and system security. Compared to most commercially
available multimedia software in the market, WWW services are cheap to run, userfriendly
and readily available to the public on the Internet. In order to exploit the potential
of WWW on transportation research, a study was carried out and results of the findings are
reported in section (4). To further substantiate the level of usefulness, two particular
WWW applications were chosen amongst other web services and they are reported in
section (5) for illustrative purposes. The selected applications are the 'Transportation
Resources on the Internet' developed in mid-1994 in the Institute for Transport Studies
(ITS) at the University of Leeds in England, and the 'Southern California Real-Time
Traffic Report' developed by Maxwell Laboratories, Inc. in collaboration with the
California State Department of Transportation in the US. Finally, a set of issues are raised
in section (6), highlighting the directions of future development of WWW as an easy-touse,
cheap and effective multimedia telematics application on transportation
Horizons and Perspectives eHealth
EHealth platform represents the combined use of IT technologies and electronic communications in the health field, using data (electronically transmitted, stored and accessed) with a clinical, educational and administrative purpose, both locally and distantly. eHealth has the significant capability to increase the movement in the direction of services centered towards citizens, improving the quality of the medical act, integrating the application of Medical Informatics (Medical IT), Telemedicine, Health Telematics, Telehealth, Biomedical engineering and Bioinformatics. Supporting the creation, development and recognition of a specific eHealth zone, the European Union policies develop through its programs FP6 and FP7, European-scale projects in the medical information technologies (the electronic health cards, online medical care, medical web portals, trans-European nets for medical information, biotechnology, generic instruments and medical technologies for health, ICT mobile systems for remote monitoring). The medical applications like electronic health cards ePrescription, eServices, medical eLearning, eSupervision, eAdministration are integral part of what is the new medical branch-eHealth, being in a continuous expansion due to the support from the global political, financial and medical organizations; the degree of implementation of the eHealth platform varying according to the development level of the communication infrastructure, allocated funds, intensive political priorities and governmental organizations opened to the new IT challenges.eHealth, telemedicine, telehealth, bioinformatics, telematics
Innovation in Automative Telematics Services: Characteristics of the Field and Management Priciples
The growing role of innovation in the strategy of car manufacturers leads them to relentlessly look for new sources of differentiation. In this way Telematics, a suite of technologies centered on communications systems within cars, is expected to bolster the car industry by offering a new stream of revenues. This articles focuses on the impact of this technology on design organization. In the first part, we demonstrate that Telematics is a radical innovation for automotive industry. Therefore traditional design models, such as heavyweight project management, are unsuitable. Next, the paper studies the organization adopted by a european car manufacturer in the light of recent research on the management of innovation.Management de projet;Services;Télématique automobile;Développement de nouveaux produits;Gestion de l'innovation
ECG Signal Reconstruction on the IoT-Gateway and Efficacy of Compressive Sensing Under Real-time Constraints
Remote health monitoring is becoming indispensable, though, Internet of Things (IoTs)-based solutions have many implementation challenges, including energy consumption at the sensing node, and delay and instability due to cloud computing. Compressive sensing (CS) has been explored as a method to extend the battery lifetime of medical wearable devices. However, it is usually associated with computational complexity at the decoding end, increasing the latency of the system. Meanwhile, mobile processors are becoming computationally stronger and more efficient. Heterogeneous multicore platforms (HMPs) offer a local processing solution that can alleviate the limitations of remote signal processing. This paper demonstrates the real-time performance of compressed ECG reconstruction on ARM's big.LITTLE HMP and the advantages they provide as the primary processing unit of the IoT architecture. It also investigates the efficacy of CS in minimizing power consumption of a wearable device under real-time and hardware constraints. Results show that both the orthogonal matching pursuit and subspace pursuit reconstruction algorithms can be executed on the platform in real time and yield optimum performance on a single A15 core at minimum frequency. The CS extends the battery life of wearable medical devices up to 15.4% considering ECGs suitable for wellness applications and up to 6.6% for clinical grade ECGs. Energy consumption at the gateway is largely due to an active internet connection; hence, processing the signals locally both mitigates system's latency and improves gateway's battery life. Many remote health solutions can benefit from an architecture centered around the use of HMPs, a step toward better remote health monitoring systems.Peer reviewedFinal Published versio
