With the switch-over to digital television in February 2009, the UHF band will become available for unlicensed use, pending the final FCC rule and order. The incumbents that need to be protected are digital television and wireless microphone signals. Some of the key requirements for an unlicensed radio to operate successfully in this band are (i) the ability to quickly and robustly sense spectr...

Computational challenges in genomics data mining and analysis are an impending roadblock in modern health-sciences research, where algorithms for DNA sequence processing grow alarmingly in computational needs as datasets from new instruments continue to dramatically expand. Reconfigurable computers featuring customizable processing devices (e.g. FPGAs) hold the key in addressing these challenge...

The relevance of flexibility resources in today’s energy systems is underestimated due to the conventional ideologies of operators and users, however, the recent rise in demand response popularity has allowed considerable changes to how and how should power systems operate. In this paper, it is presented an aggregator’s methodology to include and manage distributed energy resources, namely, dis...

New fractionation technologies are presently under investigation in order to enhance the wheat bran nutrient value. The explicit aim of the present paper was to evaluate the possibility of using the electric field forces for the separation of the fine particles generated from each wheat bran tissue during the milling process. Corona charging and surface potential decay experiments were performe...

Large-scale integration of emerging nanoscale non-volatile memory devices, e.g. resistive random-access memory (RRAM), can enable a new generation of neuromorphic computers that can solve a wide range of machine learning problems. Such hybrid CMOS-RRAM neuromorphic architectures will result in several orders of magnitude reduction in energy consumption at a very small form factor, and herald au...

This paper presents a new approach for dynamic spectrum management for heterogeneous wireless devices. Local congestion degrades the reliability of wireless applications in the License Exempt bands. This leads to the research questions: (1) how to realize equal spectrum sharing between dissimilar systems, and (2) how to improve the collective spectrum efficiency. A solution is in dynamic distri...

As interest in energy-harvesting sensor nodes continues to grow, the use of supercapacitors as energy stores or buffers is gaining popularity. The reasons for their use are numerous, and include their high power density, simple interfacing requirements, simpler measurement of state-ofcharge, and a greater number of charging cycles than secondary batteries. However, supercapacitor energy densiti...

This paper studies a stochastic age-dependent competitive population system with diffusion. The definition of exponential mean square stability of numerical method is introduced. It is proved that the Euler scheme is exponentially stable in mean square sense under the given conditions. An example is given for illustration.

The aim of the paper is to shown that in practice, the Cold Heat diagnosis of Vietnamese Traditional Medicine is better to combining positive and negative knowledge. Based on text book and experiences of Traditional medicine practitioner we build the knowledge base combining positive knowledge and negative knowledge for Cold Heat diagnosis. Then we use the FuzzRESS A Fuzzy Rule-based Expert Sys...

This paper presents a dynamic particle swarm optimization based search for optimal fusion configuration of sensors in distributed detection network in presence of a nonstationary binary symmetric channel. The wireless channel in sensor networks is a non-stationary random process, which moves the optima of the original problem, otherwise static. The optimal fusion configuration minimizes the pro...
