Historically in most inter-American countries, cardiovascular ultrasound is performed by physicians and in very few, by technicians. This practice is not expected to change substantially in the near future. In some countries, echocardiograms are performed by general cardiologists without specific training. Only a few inter-American countries offer formal echocardiography training programs. In i...
Mobile Ad Hoc Network (MANET) applications such as multimedia applications, audio/video conferencing, VOIP and webcasting need uninterrupted, stringent and inflexible Quality of Service (QoS). The provision of QoS guarantees in MANET is more challenging and difficult than wired network because of node mobility, lack of centralized control and a limited power supply. A lot of researches have bee...
When I took over the editorial office of the European Heart Journal in the autumn of 2002 the flow of papers was mainly handled manually, and online submission did not even exist. Today more papers are read on the website of the journal than on paper, and an efficient electronic platform distributes manuscripts for review around the world in a few seconds. The use of the internet had a tremendo...
A Mobile Ad-hoc Network (MANET) is composed of mobile nodes without any infrastructure. MANET applications such as audio/video conferencing, webcasting requires very stringent and inflexible Quality of Service (QoS). The provision of QoS guarantees is much more challenging in MANETs than wired networks due to node mobility, limited power supply and a lack of centralized control. Many researches...
This paper presents a novel method for cooperative educational dissemination systems. Taking into consideration the inherent characteristics of distance learning video streams (existence of a few slow moving objects in a classroom), we have proposed a novel content-based video coding method that is very e cient at low bitrate channels. On the encoding side, we have applied a background subtract...
In this article, we present and describe current ideas in Virtual Reality Modeling Language (VRML) technology such as focused mostly on integrating VRML with other technologies Geographical Information System (GIS) and Global Positioning System (GPS) applied as new Internet services called Virtual World Webcasting (VWW). The VWW technology is considered a new web communication paradigm, definin...
Various real-time services, like webcasting, audio/videoconferencing and telemedicine, are being deployed over the Internet. This requires the network to provide the guarantee of the service being provided to the receiver. The needs of the application is specified in terms of the Quality of Service (QoS) metrics like desired bandwidth, response time, etc. End-to-end QoS can be provided most eff...
BACKGROUND CONTEXT The North American Spine Society's (NASS) Evidence-Based Clinical Guideline for the Diagnosis and Treatment of Degenerative Lumbar Spondylolisthesis features evidence-based recommendations for diagnosing and treating degenerative lumbar spondylolisthesis. The guideline updates the 2008 guideline on this topic and is intended to reflect contemporary treatment concepts for symp...
It is generally agreed upon that Information and Communication Technologies (ICT) are of vital importance for the social and economical development of a country. Following this idea, various initiatives have been made to address technical, cultural, rural and community development issues through projects of digital inclusion, with the direct or indirect supervision of international institutions...
In recent years, interest in virtual trade shows, virtual conferences, and other online events has been visibly growing. Virtual conference technologies allow for sharing presentations, facilitating discussions, stimulating conversations, and providing networking opportunities to large groups of people and over prolonged periods of time through interactive environments that are user friendly, m...
