Computers, communication, and sensing technologies are converging to change the way we live, interact, and conduct business. Wireless sensor networks reçect such convergence. These networks are based on collaborative efforts of a large number of sensor nodes. They should be low-cost, low-power, and multifunction. These nodes have the capabilities of sensing, data processing, and communicating. Sensor networks have a wide range of applications, from monitoring sensors in industrial facilities to control and management of energy applications to military and security fields. Because of the special features of these networks, new network technologies are needed for cost effective, low power, and reliable communication. These network protocols and architectures should take into consideration the special features of sensor networks such as: the large number of nodes, their failure rate, limited power, high density, etc. In this talk the impact of wireless sensor networks will be addressed, several of the design and communication issues will be discussed, and a case study of a current project of using such networks in drilling and management off-shore oil and natural gas in the gulf region will be given.

The Design of High-Speed Low-Power Digital FIR Filters Based on Frequency-Response Masking Technique
Dr. Yong Lian
Department of Electrical and Computer Engineering
National University of Singapore
The digital filters are basic building blocks in many digital signal processing systems. Finite impulse response (FIR) filters are often desirable due to their guaranteed stability and linear phase characteristics. However, the arithmetic complexity of an FIR filter becomes very high if a long filter is needed to meet the stringent frequency-selective specifications. The VLSI implementation of a long FIR filter requires great computational resources, large silicon area, and high power. Frequency-response masking (FRM) technique is one of the most computationally efficient techniques for synthesizing arbitrary bandwidth sharp FIR filters. In some cases the reduction on the number of multipliers can be as high as 98%. The basic idea of the FRM technique is to compose a sharp FIR filter using several short filters. There are two stages in an FRM approach. The first stage is to produce the sharp transition band and arbitrary bandwidth by a pair of interpolated complementary band-edge shaping filters, whereas the second stage forms the overall filter by removing the undesired periodic frequency components from the band-edge shaping filters using two masking filters. The interpolation of band-edge shaping filter leads to a filter with sparse coefficients. Such a sparse coefficient filter not only achieves great savings in the number of multipliers and adders, but also reduces the power consumption significantly when such a filter is implemented in an ASIC. The high efficiency of the FRM technique makes it very attractive for the modern filter design, especially for the low-power applications. The talk will present the most recent developments in the FRM technique including various modified FRM structures that yield additional savings in the number of arithmetic operations, high-speed low-power filters based on FRM technique, and implementation issues of FRM based filters.

Algebraic methods and optimization for signal processing and source separation of multiway signals and data sets.
Dr. Joos Vandewalle
Electrical Engineering Department (ESAT),
Katholieke Universiteit Leuven, Belgium
The singular value decomposition of a matrix, and its generalizations are an important algebraic method for seperating signals and sources. Applications range over telecommunication, biomedical signal processing and bioinformatics, and information retrieval. Concepts of oriented energy and oriented signal to signal ratio are important conceptual methods in this respect. Generalizations to multi-way data sets and signals require extensions to of these decompositions and signal to signal ratios to tensors. In the presentation we discuss such generalizations and their use in applications. Such concepts have interesting geometric interpretations in terms of vector spaces and linear algebra, and have a great potential for design of algorithms in signal processing and data processing.

A 3D Simplicial CNN Structure: Architecture and Circuit Realization
Dr. Pedro Julian
Universidad Nacional del Sur, Argentina
Three dimensional (3D) integration is an emerging technology that allows the interconnection of several wafers of integrated circuits (IC) on a vertical direction by small metallic plugs called vias. The effectiveness of the approach finds justification when the vias size drops below some micrometers square allowing high density wafer-to-wafer interconnection. The main advantage of this technology is that t permits to increase density by allowing the integration of several "floors" of ICs. Moreover, in the near future this technology will allow the combination of different types of wafers for dedicated high performance systems.
This talk will describe the system architecture of an integrated circuit consisting of an imager with pixel processing capabilities in the 3D technology, inspired on a CNN-type structure.
Pedro M. Julian (S'94, M'00) was born in the city of Bahía Blanca, Argentina, on June 28, 1970. He received the "Ingeniero Electronico" degree in 1994 and the Ph.D. degree in "Control de Sistemas" in 1999, both from Universidad Nacional del Sur (UNS).

Dr. Ljiljana Trajkovic

Traditional statistical analysis of network data is often employed to determine traffic distribution, to summarize patterns of user behavior, or to predict future network traffic. Mining of network data may be used to characterize user behavior patterns, to discover hidden user groups, to detect payment fraud, or to identify network abnormalities. We combine this traditional traffic analysis with data mining techniques and analyze traffic data collected from a deployed public safety trunked radio network. After data cleaning and traffic extraction, we identify clusters of talk groups by applying clustering algorithms on patterns represented by the hourly number of calls. Traffic prediction models are then developed by applying classical prediction models on the aggregate and clustered data. Cluster-based prediction approaches, while less computationally demanding, perform well compared to the prediction based on the aggregate traffic.
