In this paper we present Polimedia as an alternate way of producing video learning objects instead of lecture recording. We are using heavily this technology with a teacher support program involving more than two hundred teachers and in this time we have produced more than two thousand Polimedia learning objects and we have also disseminated this technology with several universities. We present also...
There are several IEEE 802.11 variants to interconnect several wireless devices. Usually, a variant is chosen based on their bandwidth and their coverage area. However, sometimes, there are special cases where the best technology is not the newest one. E.g., in the case where devices are going to transmit at a maximum of 1 Mbps, any choice is acceptable. In this paper, we are going to compare IEEE...
This paper discusses the development of a multimedia training material and the possibilities of using Information and Communications Technologies (ICT) for delivering Continuing Engineering Education and Life-Long Learning. A special remark should be done on the use of web technologies and media authoring tools for Antenna Courses.
Wireless local area networks are becoming necessary in university campuses and enterprise areas. Taking advantage of this technology, many benefits can be obtained. One of them is the use of the user's mobility information when there is ubiquity in the wireless network. This information can tell us which places are most visited, if people have to go to places that are far from their office, detect...
With the adoption of the wireless LAN technology as one of the main ways to access the enterprise network, IP services have found another place where they can be implemented. In this paper we will show the test and performance used to develop the IP telephony network over the 802.11g wireless LAN of the Polytechnic University of Valencia. In order to make these measurements, we have used the open...
One of the multimedia services offered by the campus network of the Polytechnic University of Valencia is TV over IP. This service works well in the devices connected directly to the wired network but we have detected some problems when the receivers access to the campus network through wireless IEEE 802.11, especially when devices roam across the campus. In this paper we propose and evaluate a server-based...
Wireless IP telephony is becoming very popular between the users of large wireless local area networks (WLANs). This increment has been mainly caused because it allows cost savings. Although, large WLANs use to provide high availability and redundancy, WLANs lack on the available throughput when there are many IP telephony users. In this paper we present a system that reallocates IP telephony devices...
One of the biggest concerns in e-learning is the development of suitable content. To reuse standard Webcast content for mobile phones and smartphones we have designed and tested a content adaptation system that enables the presentation & reuse of Webcast multimedia content for resource limited mobile terminals. In particular, our system approach the limitations related to small screen displays...
Vectorial photoinduced electron transfer was investigated in Langmuir-Blodgett bilayers and in vesicles with the same phospholipid composition. The donor was covalently bound to one of the hydrophobic chains of the phospholipid in the mimetic membrane, whereas the acceptor was adsorbed at the polar head group surface. The location of the redox couple was preliminarily determined studying the photophysical...
