The use of mobile telephony has shown a spectacular growth in the last 10 years. A side effect of this rapid growth is an excess of mobile system standards. Therefore, the Software-Defined-Radio (SDR) concept is emerging as a potential pragmatic solution: it aims to build flexible radio systems, which are multi-service, multi-standard, multiband, re-configurable and re-programmable, by software...

CMOS radio receiver architectures, based on radio frequency (RF) sampling followed by discrete-time (DT) signal processing via switched-capacitor circuits, have recently been proposed for dedicated radio standards. This paper explores the suitability of such DT receivers for highly flexible softwaredefined radio (SDR) receivers. Via symbolic analysis and simulations we analyze the properties of...

The myriad of connected devices in today’s households have greatly increased the complexity of home networks. Evolving use cases demand new networking capabilities in the home and call for new approaches to deal with the control requirements and quality of experience expectations of end users. OpenFlow/SDN represents a recent trend in open interfaces to network elements and new control plane ab...

The constantly growing body of scholarly knowledge of science, technology, and humanities is an asset of the mankind. While new discoveries expand the existing knowledge, they may simultaneously render some of it obsolete. It is crucial for scientists and other stakeholders to keep their knowledge up to date. Policy makers, decision makers, and the general public also need an efficient communic...

Our goal as education researchers is to make a difference. We want to help students learn better, or perhaps we want them to learn just as well but at lower cost to our institutions. Decades of research tell us that it is difficult to make a significant difference with technology. This is especially true if we are trying to do the same things. The true value of new technology comes when it perm...

The global regulatory plan for vaccines provides a unique opportunity to develop safe and effective ones with assured quality. Methods used by regulators address challenges of new products and technologies and also increase understanding of benefits and risks of existing products. First, the laboratory-based regulatory sciences evolve correlates of immunity and safety; or improve the product ch...
