Modern cellular communication systems are based on frequency reuse 1. Although reuse 1 promises high peak data rates and significantly simplified network planning, the cell edge or cell overlap areas suffer from excessive inter-cell interference. In this work we address interference management for downlink part of these systems. Part of the radio resources is primarily reserved for protected access of vulnerable users. The protected access is based on a novel sounding/silencing protocol that takes advantage of instantaneous signal to interference plus noise ratio prediction and has power to silence strong interferers with low priority. The accompanied signaling scheme is developed for time division duplex systems. Our results in an indoor scenario with partly overlapping closed subscriber groups show that even with realistic control signal reception model the proportion of zero throughput users can be reduced by more than 50%.

This work addresses a rather challenging and interesting interdisciplinary educational issue. It integrates the analysis and evaluation of natural brain language processing with phonics reading (pronunciation) methodology. Specifically, presented paper concerned with searching for an optimal educational methodology for teaching children “how to read?”. That's by adopting a simplified neuronal mechanism observed model while human brain speech / pronunciation function is performed. Consequently, the presented modeling of phonics reading methodology adopts the observed behavioral characterizations of brain neural networks. Additionally, mathematical formulation is given considering the suggested reading methodology. Objectively, in order to justify its optimality in teaching children how to read. It's motivated by a biologically (naturally) inspired artificial neural network (ANN) model considering associative brain function, between two visual and audible signals. Accordingly, the mathematical formulation introduced herein, has been fulfilled realistically via ANN modeling of self-organized learning paradigm, originated from biological basis of Hebbian learning rule.

IEEE/SP Workshop on Statistical signal processing (SSP)

Djurić Signal Processing Applications Group Universidad Politecnica de Madrid Spain Center of Excellence in Wireless and Information Technology Stony Brook University USA School of Information Technology and Engineering University of Ottawa Canada Department of Electrical & Computer Engineering Stony Brook University USA

In this paper, we propose a particle filtering (PF) method for indoor tracking using radio frequency identification (RFID) based on aggregated binary measurements. We use an Ultra High Frequency (UHF) RFID system that is composed of a standard RFID reader, a large set of standard passive tags whose locations are known, and a newly designed, special semi-passive tag attached to an object that is tracked. This semi-passive tag has the dual ability to sense the backscatter communication between the reader and other passive tags which are in its proximity and to communicate this sensed information to the reader using backscatter modulation. We refer to this tag as a sense-a-tag (ST). Thus, the ST can provide the reader with information that can be used to determine the kinematic parameters of the object on which the ST is attached. We demonstrate the performance of the method with data obtained in a laboratory environment.

Djurić Center of Excellence of Wireless and Information Technology Stony Brook University USA Signal Processing Applications Group Universidad Politecnica de Madrid Spain School of Information Technology and Engineering University of Ottawa Canada Department of Electrical & Computer Engineering Stony Brook University USA

In this paper we present a novel Radio Frequency Identification (RFID) system for accurate indoor localization. The system is composed of a standard Ultra High Frequency (UHF), ISO-18006C compliant RFID reader, a large set of standard passive RFID tags whose locations are known, and a newly developed tag-like RFID component that is attached to the items that need to be localized. The new semi-passive component, referred to as sensatag (sense-a-tag), has a dual functionality wherein it can sense the communication between the reader and standard tags which are in its proximity, and also communicate with the reader like standard tags using backscatter modulation. Based on the information conveyed by the sensatags to the reader, localization algorithms based on binary sensor principles can be developed. We present results from real measurements that show the accuracy of the proposed system.

In traffic monitoring applications, traffic speed is an important parameter of traffic management. The method for traffic speed measurement using video based on Spatio-Temporal (ST) model and frequency domain analysis is proposed in this paper. This method is designed to be able to measure the traffic speed in every pattern of road. The novel of proposed method is unfolding the edge information on ST model and analyse them in frequency domain to determine traffic speed. The proposed method is evaluated by compare with actual speed. The traffic speed is measured accurately 97.1%.

Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases that block airflow and cause a huge degree of human suffering. While there is no cure for COPD and the lung damage that results in this disease cannot be reversed, it is very important to diagnose it as early as possible. Additional to diagnosis, using a mathematical model to estimate severity of disease would be helpful for evaluation of treatment effects. This paper presents a new method for identifying COPD from three-dimensional (3-D) pulmonary X-ray CT images. The method has five main steps. First, corresponding positions of lungs in inspiration and expiration are found based on anatomical structures. Then, lung regions are segmented from the CT images by active contours. Next, the left and right lungs are separated using a sequence of morphological operations. Then, parenchyma variations in each lung are found as a relationship between inspiratory and expiratory states. Finally, a classifier is used to decide about the disease and its severity. A t-test is done to evaluate the results. Twelve patients with variable severity of COPD and twelve normal adults were included in this study. The proposed method may assist radiologists in the detection of COPD as a computer aided diagnosis (CAD) system.

Assessing lung volumetric variation to detect and stage COPD

Assessing lung volumetric variation to detect and stage COPD

Middle East Conference on Biomedical engineering (MECBME)

Chronic obstructive pulmonary disease (COPD) is a devastating disease. In this paper, we propose a novel method for scoring of air trapping in the lungs for detection and evaluation of COPD. The proposed method finds volumetric changes of the lungs from inspiration to expiration. To this end, trachea CT images at full inspiration and expiration are compared. For this comparison, the lungs parenchyma in the inspiration and expiration images are found and changes in the surface and volume of the lungs between inspiration and expiration are used to define quantitative measures (features). Using these features, the subjects are classified into two groups of normal class and COPD patients using a Bayesian classifier. In addition, t-tests are applied to evaluate discrimination powers of the features for this classification. The main advantage of the proposed method is its ability to estimate air trapping in the lungs from CT images without human intervention. The proposed method may assists radiologists in the detection of COPD as a computer aided diagnosis (CAD) system. It may also assist them with the scoring of the disease (severity of air trapping in the lungs).

The regulation of gene expression is a dynamic p rocess, hence it is of vital interest to identify and characterize these dynamic processes. Since genes work in a cascade of networks, gene regulatory network (GRN) reconstruction is a crucial process for thorough understanding of the underlying biological interactions. We present here a technique based on partial correlations to infer the GRN. Our proposed technique takes into account the possible and variable time delays between various genes. The results have shown that our proposed a lgorithm has results consistent with the existing biological knowledge. Our algorithm is implemented in R. © 2010 IEEE.

In this paper we investigate the local probability density function (pdf) of natural signals in sparse domains. The statistical properties of natural signals are characterized more accurately in the sparse domains because the sparse domain coefficients (SDCs) have heavy-tailed distribution and have reduced correlation with adjacent coefficients. Our experiments show that a conditionally (given locally estimated variance and shape) independent Bessel K-form (BKF) pdf locally fits the sparse domain's coefficients of natural signals, accurately. To justify this observation, we also investigate the pdf of the locally estimated variance and suggest a Gamma pdf for the locally estimated variance. Since commonly used sparse transformations are orthonormal, the pdf of the sparse domain coefficients must converge to Gaussian distribution by virtue of central limit theorem assuming that natural signals are locally wide sense stationary for small window sizes. Interestingly, we observe that the pdf of the normalized data (on the locally estimated variance) exhibit a Gaussian pdf, which justifies why the BKF pdf is an appropriate fit.

We present developments in the search for engineered radio emissions from advanced extraterrestrial life. Our group is currently engaging in both targeted and sky survey searches for extraterrestrial intelligence (SETI), covering a wide variety of narrow-band and pulsed signal types. We are also developing new SETI instrumentation, designed to be flexible, modular and to employ commodity components that lower cost and enhance upgradability. Here we will discuss the status of these observational and engineering projects, as well as prospects for future radio SETI endeavors.
