Sequestration of Malevolent Anchor Nodes in Wireless Sensor Networks using Mahalanobis Distance [PDF]
arXiv, 2014 Discovering the malicious or vulnerable anchor node is an essential problem in wireless sensor networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location. Neighbouring nodes or non-anchor nodes calculate its location coordinate (or location reference) with the help of anchor nodes.

Simplified 2D Bidomain Model of Whole Heart Electrical Activity and ECG Generation
Measurement Science Review, 2014 The aim of this study was the development of a geometrically simple and highly computationally-efficient two dimensional (2D) biophysical model of whole heart electrical activity, incorporating spontaneous activation of the sinoatrial node (SAN), the ...

On the condition number of Vandermonde matrices with pairs of nearly-colliding nodes [PDF]
arXiv, 2018 We prove upper and lower bounds for the spectral condition number of rectangular Vandermonde matrices with nodes on the complex unit circle. The nodes are "off the grid", pairs of nodes nearly collide, and the studied condition number grows linearly with the inverse separation distance.

Percolation on the Information-Theoretically Secure Signal to Interference Ratio Graph [PDF]
arXiv, 2013 We consider a continuum percolation model consisting of two types of nodes, namely legitimate and eavesdropper nodes, distributed according to independent Poisson point processes (PPPs) in $\bbR ^2$ of intensities $\lambda$ and $\lambda_E$ respectively.

JACC: Basic to Translational Science, 2018 Summary: Sinoatrial node (SAN) disease mechanisms are poorly understood, and therapeutic options are limited. Natriuretic peptide(s) (NP) are cardioprotective hormones whose effects can be mediated partly by the NP receptor C (NPR-C). We investigated the

Artificial Cardiac Conduction System: Simulating Heart Function for Advanced Computational Problem Solving [PDF]
arXivThis work proposes a novel bio-inspired metaheuristic called Artificial Cardiac Conduction System (ACCS) inspired by the human cardiac conduction system. The ACCS algorithm imitates the functional behaviour of the human heart that generates and sends signals to the heart muscle, initiating it to contract.

Crowd collectiveness measure via graph-based node clique learning [PDF]
arXiv, 2016 Collectiveness motions of crowd systems have attracted a great deal of attentions in recently years. In this paper, we try to measure the collectiveness of a crowd system by the proposed node clique learning method. The proposed method is a graph based method, and investigates the influence from one node to other nodes.

Avoidance Markov Metrics and Node Pivotality Ranking [PDF]
arXiv, 2018 We introduce the avoidance Markov metrics and theories which provide more flexibility in the design of random walk and impose new conditions on the walk to avoid (or transit) a specific node (or a set of nodes) before the stopping criteria. These theories help with applications that cannot be modeled by classical Markov chains and require more ...
