Human Activity Recognition: Discriminative Models Using Statistical Chord-Length And Optical Flow Motion Features, Mahmoud Elmezain, Essam O. Abdel-Rahman

Applied Mathematics & Information Sciences

Despite the vast amount of research on the analysis of existing and ongoing human activity, there are still significant challenges worthy of address. In this paper, an innovative approach for human action recognition based on discriminative models like CRFs, HCRFs and LDCRFs is proposed. To handle human action recognition, different number of window size ranging from 0 to 7 are applied using a compact computationally-efficient descriptor as statistical chord-length features (SCLF), in addition to optical flow motion features that derived from 3D spatio-temporal action volume. Our experiment on a standard benchmark action KTH, as well as our IIKT dataset show …

Applied Mathematics & Information Sciences

Prior research on the subject of visualisation of three-dimensional (3D) objects by coordinate systems has proved that all objects are translated so that the eye is at the origin (eye space). The multiplication of a point in eye space leads to perspective space, and dividing perspective space leads to screen space. This paper utilised these findings and investigated the key factor(s) in the visualisation of 3D objects within 3D maps on mobile devices. The motivation of the study comes from the fact that there is a disparity between 3D objects within a 3D map on a mobile device and those …

A More Secure Dynamic Id-Based Remote Authentication Scheme Using Smart Cards, Dianli Guo, Fengtong Wen, Chengbo Xu

Applied Mathematics & Information Sciences

In 2013, Chang et al. proposed an untraceable dynamic-identity-based remote user authentication scheme with verifiable password update. In this paper, we analyze Chang et al.s scheme and show that their scheme suffers from off-line password guessing attack, server spoofing attack and impersonation attack. Moreover, their scheme is traceable since the attacker can obtain the identity of the user. Thereby, we propose an alternative scheme based on elliptic curve cryptosystem and completely automated public turing test to tell computer and humans apart (CAPTCHA) technique. Besides, we demonstrate the completeness of the proposed scheme through the BAN-logic. Compared with other related existing …

Energy Minimization By Optimally Relocating Mobile Relays In Multi-Hop Wireless Ad Hoc Networks, Seokhoon Yoon

Applied Mathematics & Information Sciences

This paper considers the energy minimization problem in a multi-hop wireless ad hoc network that consists of regular nodes and mobile relays. In such a network, mobile relays may relocate to optimal positions such that energy consumption for data transmission isminimized. In order to find the optimal positions for mobile relays, the mobile relay optimal relocation (MROR) problem is first defined. Since the cost in terms of data transmission energy can be modeled using a convex function, the problem is formulated as a convex optimization problem over mobile relay position variables. Using dual decomposition and subgradient methods enables mobile relays …

Applied Mathematics & Information Sciences

On-line/off-line threshold proxy re-signatures can efficiently improve the the performance of threshold proxy re-signature schemes. A simulation theorem for on-line/off-line threshold proxy re-signature schemes is presented in this paper.

Furthermore, we propose an on-line/off-line threshold proxy re-signature scheme which is proven secure (unforgeable and robust) under the computational Diffie-Hellman assumption and the discrete logarithm assumption. The on-line phase …

Improved Iterative Sparseness For Least Squares Support Vector Machines, Zhong Lu-Sheng, Chen Li-Yong, Gong Jin-Hong, Zhu Zhen-Min Nov 2015

Improved Iterative Sparseness For Least Squares Support Vector Machines, Zhong Lu-Sheng, Chen Li-Yong, Gong Jin-Hong, Zhu Zhen-Min

Applied Mathematics & Information Sciences

An improved iterative sparse algorithm is proposed to accelerate the execution of sparse least squares support vector machines(LS-SVM). Firstly, the technique of iterative approximation to the L0-norm is used to sparsify the LS-SVM for regression. However, each iteration requires solving a linear system with expensive computation compared to training a single LS-SVM. In this paper, improved conjugate gradient (ICG) method is given to reduce the computational cost, which is based on transforming the constrained primal problem in LS-SVM into an unconstrained minimization problem. Then the solution to the unconstrained minimization problem is obtained by using the CG method only once …

A Colorless, Directionless And Contention-Less Roadm That Utilizes Interconnected Wsss, Li Zhao, Weiqiang Sun, Weisheng Hu

Applied Mathematics & Information Sciences

We propose a novel colorless, directionless and contention-less (CDC) reconfigurable optical add/drop multiplexer (ROADM) that is composed of interconnected wavelength selective switches (WSSs). The key components of this ROADM are interconnected WSSs. Using the connecting branches from WSS to WSS, the channels at any wavelengths from any input may exploit any transponder in the photonic ROADM node. Both of simulation and analytical results showed that when the number of connecting branches (r) equals 2, same blocking performance may be achieved as CDC case (where r equals to N-1). Meanwhile, it achieves significant capital expense saving when compared with other equivalent …


Asian Options With Harmonic Average, Fares Al-Azemi, Ovidiu Calin Nov 2015

Asian Options With Harmonic Average, Fares Al-Azemi, Ovidiu Calin

Applied Mathematics & Information Sciences

The foreign exchange markets felt the necessity of using contracts written on harmonic averages. They are attractive because are cheaper than the contracts written on the arithmetic average, and make more financial sense than contracts written on geometric averages. The goal of this paper is to consider Asian options and future contracts on harmonic averages of stock values. Since the harmonic average of a set of lognormal random variables does not have an explicit representation, a close-form pricing formula for options and futures is missing. However, we obtain the value of a future contract expressed as an infinite series and …


Squeezed Versus Non-Gaussian Fluctuations In Resonance Fluorescence, Héctor M. Castro-Beltr?N, Luis Gutiérrez, Levente Horvath Nov 2015

Squeezed Versus Non-Gaussian Fluctuations In Resonance Fluorescence, Héctor M. Castro-Beltr?N, Luis Gutiérrez, Levente Horvath

Applied Mathematics & Information Sciences

We study theoretically the fluorescence of a two-level atom driven by a laser of weak to moderate intensity, that is, a regime where squeezing would occur. Close to saturation atomic fluctuations dominate and become non-Gaussian, degrading the squeezing. Using Bloch equations and quantum jump trajectories we find that allowing a moderate degree of non-linearity, conditional homodyne detection [G.T. Foster, L.A. Orozco, H.M. Castro-Beltran, H.J. Carmichael, Phys. Rev. Lett. 85, pp. 3149-3152, 2000] would actually help in observing the elusive squeezing in the fluorescence by increasing the size of the characteristic negative spectrum.

A number of studies have shown that facial expression representations are cultural dependent and not universal. Most facial expression recognition (FER) systems use one or two datasets for training and same for testing and show good results. While their performance mortify radically when datasets from different cultures were presented. To keep high accuracy for a long time and for all cultures, a FER system should learn incrementally. We proposed a FER system that can offer incremental learning capability. Local Binary Pattern (LBP) Features are used for Region of Interest (ROI) extraction and classification. We used static images of facial expressions …
