The vision of nomadic computing with its ubiquitous access has stimulated much interest in the mobile ad hoc networking (MANET) technology. However, its proliferation strongly depends on the availability of security provisions, among other factors. In the ...
Numerous approaches have been proposed to manage Quality of Service in the Internet. However, none of them was successfully deployed in a commercial IP backbone, mostly because of their complexity. In this paper, we take advantage of the excess network ban ...
In this paper, we present five case studies of advanced networking functions and how a network processor (NP) can provide high-performance and exible support for each of them. We first review the basic NP system architectures, and describe in more detail t ...
Through the sequential use of classical molecular dynamics and first-principles relaxation methods, we generate an abrupt model interface for the 4H(0001)SiC-SiO2 interface showing regular structural parameters without any coordination defect. The bond den ...
In this paper, we present a video encoding scheme that uses object-based adaptation to deliver surveillance video to mobile devices. The method relies on a set of complementary video adaptation strategies and generates content that matches various applianc ...
We present the results of an exptl. and theor. study on the optimum design of shear-force sensors, used in scanning probe microscopes. We have optimized a configuration consisting of a tuning-fork/fiber-tip assembly, achieving quality factors (Q) exceeding ...
We address the quantitative comparison of two basic connection schemes for on-chip communication, connection-oriented and connection-less, regarding their enforcement of a defined Quality-of-Service for the communication. For such comparison, we have built ...
Networks on Chips (NoCs) have evolved as the communication design paradigm of future Systems on Chips (SoCs). In this work we target the NoC design of complex SoCs with heterogeneous processor/memory cores, providing Quality-of-Service (QoS) for the applic ...
To be reliable, an automatic segmentation evaluation metric has to be validated by subjective tests. In this paper, a formal protocol for subjective tests for segmentation quality assessment is presented. The most common artifacts produced by segmentation ...
Severely disabled people are largely excluded from the benefits information and communication technologies have brought to our industries, economies, appliances, and general quality of life. But what if that technology would allow them to communicate their ...
