With limited bandwidth and high channel loss in wireless body area networks (WBANs), it remains a challenging issue to transmit time series body sensor data for satisfactory data analytics. In this paper, we investigate the interesting problem of sample packetization, i.e., assembling multiple samples in each packet before transmission over the wireless link. We first illustrate the ineffectiveness...
In this paper, we investigate the outage probability in decoding the rateless codes when a certain amount fountain encoded symbols are generated, and then transmitted through a memoryless erasure channel (MEC). We obtain a closed-form formula for the outage probability by accounting for the complete effect of the channel on the distribution of the received symbols. Moreover, a new model with high...
Medical databases have been a popular application field for image retrieval techniques during the last decade. More recently, much attention has been paid to the prediction of medical image modality (X-rays, MRI…) and the integration of the predicted modality into image retrieval systems. This paper addresses these two issues. On the one hand, we believe it is possible to design specific visual descriptors...
The design and development of analog/mixed-signal (AMS) ICs is becoming increasingly expensive, complex, and lengthy. Lacking a reconfigurable platform, analog designers are denied the benefits of rapid prototyping, hardware emulation, and smooth migration to advanced technology nodes. To overcome these limitations, this work proposes a new approach that maps any AMS design problem to a transistor-level...
Metabonomics is an emerging field providing insight into physiological processes and difference. Besides conventional PCA, PLS and OPLS approaches, more and more machine learning classifiers are likely to become the supplements for metabolic profiling data analysis. A comprehensive comparison of PLS, support vector machine (SVM, with linear and quadratic kernels), linear discriminant analysis (LDA),...
Distributed localization algorithm continues to be an important and challenging topic in today's wireless sensor networks (WSNs). The accurate estimations of distances among nodes are premises for the accurate estimations of node positions. In this paper, we propose some schemes towards the DV-Hop algorithm to improve the distance estimations. These improvements are based on accurate analysis of hop...
In the paper, the definition of the military equipment logistics supplying chain and the key importance of military equipment logistics information are expatiated, the model of the information flow control is introduced. Basing on the actual military material supply chain, the system framework on information flow integration-based military equipment logistics supply chain is put forward.
/sup A/ new approach to handle inductance effects for multiple signal lines is presented. The worst-case switching pattern is first identified. Then a numerical approach is used to model the effective loop inductance (L/sub eff/) for multiple lines. Based on a look-up table for L/sub eff/, an equivalent single line model can be generated to decouple a specific signal line from the others to perform...
