Speech Title: Evolution and Application of Signal (Data) Prediction
Abstract: From time immemorial human beings have shown desire to predict the future of many phenomena that pose danger to them and their properties. Examples of such could be kaleidoscopic weather, capricious earthquake, turbulent stock market, and inconsistent heartbeat just to name a few. Rudolf Wolf (1848) devised a method for the daily estimation of solar activity by counting the number of individual spots and groups of spots on the sun surface which can be considered a classical approach of measuring the level of disturbances in the earth's magnetic field: solar activity can cause satellite drag, telecommunication outages, huge electrical currents in power lines as well as radio wave propagation problem. Yule (1927) introduced regression analysis for the prediction of sunspots in order to obtain more accurate primary periodicity in sunspot numbers as well as to search for additional periodicities in the data. It is important to note that the Yule method is reminiscent to the data fitting procedure of Baron de Prony (1795) which is a method of fitting an exponential model to a set of data representing pressure and volume of a gas. In another development, Walker (1931) generalized Yule approach (modeling of disturbed harmonics data) by proposing autoregressive model (applicable to any form of data) which was applied to the analysis of the atmospheric data, leading to the discovery of the Walker circulation. The combination of these two techniques led to what is known as Yule-Walker equation (YWE) which forms the basis of signal modelling or linear prediction. YWE and its variants have been widely used in many fields of science, engineering and economics. Signal (Data) prediction has therefore evolved to be an important aspect of digital signal processing which has been successfully used to solve variety of problems in communication, control, biomedicine, geophysics, atmospheric science, and this list could continue. Signal models, which could be either parametric (with an assumption of certain functional form) or nonparametric techniques, entail efficient mathematical representation of data or signal so as to extract desirable information from either the signal or the system that generates it. Though several signal models are available, both the AR and ARMA models are widely used in many application areas as they possess some desirable properties. Consequently, a lot of research efforts have been concentrated on these two models since the last four decades. This presentation examines the theoretical framework of signal models, especially with respect to the AR and ARMA models. The shortcomings of these statistical approaches are then discussed. In recent times, there seems to be paradigm shift in signal modeling approach. The availability of very power computer combined with the emergence of machine learning, typified by artificial neural networks and genetic algorithms has made it possible to develop complex algorithms for the estimating of the model parameters. The exploitation of this so called intelligent signal modeling approach is also examined here. The presentation is concluded by evaluating the performance of aforementioned techniques in transient signal analysis, earthquake prediction, consumer load prediction for theft classification and detection, seamless mobility in wireless communication, and parameter estimation of time-varying signals.

Speech Title: Timing Synchronization and Node Localization in Wireless Sensor Networks
Abstract: Wireless sensor networks consist of a large number of sensor nodes, capable of on-board sensing and data processing, that are employed to observe some phenomenon of interest. With their desirable properties of flexible deployment, resistance to harsh environment and lower implementation cost, wireless sensor networks envisage a plethora of applications in diverse areas such as industrial process control, battlefield surveillance, health monitoring, and target localization and tracking. This presentation will focus on deriving efficient estimators and performance bounds for the clock parameters in wireless sensor networks. Identifying the close connections between the problems of node localization and clock synchronization, we also address in this presentation the problem of joint estimation of an unknown node's location and clock parameters by incorporating the effect of imperfections in node oscillators. A review of the state-of-the-art results and open research problems will be also presented.
