Microseismic events enhancement and detection in sensor arrays using autocorrelation based filtering
Entao Liu, Lijun Zhu, Anupama Govinda Raj +4
Passive microseismic data are commonly buried in noise, which presents a significant challenge for signal detection and recovery. For recordings from a surface sensor array where e…
Handover Management in 5G and Beyond: A Topology Aware Skipping Approach
Rabe Arshad, Hesham ElSawy, Sameh Sorour +2
Network densification is found to be a potential solution to meet 5G capacity standards. Network densification offers more capacity by shrinking base stations' (BSs) footprints, th…
Secure and Energy-Efficient Beamforming for Simultaneous Information and Energy Transfer
Ali A. Nasir, Hoang D. Tuan, Trung Q. Duong +1
Next-generation communication networks will likely involve the energy-efficient transfer of information and energy over the same wireless channel, for which the physical layer will…
Sparse Multichannel Blind Deconvolution of Seismic Data via Spectral Projected-Gradient
Naveed Iqbal, Entao Liu, James H. McClellan +1
In this work, an efficient numerical scheme is presented for seismic blind deconvolution in a multichannel scenario. The proposed method iterate with wo steps: first, wavelet estim…
A realistic transport model with pressure dependent parameters for gas flow in tight porous media with application to determining shale rock properties
Iftikhar Ali, Nadeem A. Malik
Shale gas recovery has seen a major boom in recent years due to the increasing global energy demands; but the extraction technologies are very expensive. It is therefore important…

A semidiscrete Galerkin finite element method applied to time-fractional diffusion equations with time-space dependent diffusivity on bounded convex spatial domains will be studied…
A Multiband OFDMA Heterogeneous Network for Millimeter Wave 5G Wireless Applications
Solmaz Niknam, Ali A. Nasir, Hani Mehrpouyan +1
Emerging fifth generation (5G) wireless networks require massive bandwidth in higher frequency bands, extreme network densities, and flexibility of supporting multiple wireless tec…
Image Denoising Via Collaborative Support-Agnostic Recovery
Muzammil Behzad, Mudassir Masood, Tarig Ballal +2
In this paper, we propose a novel image denoising algorithm using collaborative support-agnostic sparse reconstruction. An observed image is first divided into patches. Similarly s…
A Delay-Tolerant Potential-Field-Based Network Implementation of an Integrated Navigation System
Rachana Ashok Gupta, Ahmad A. Masoud, Mo-Yuen Chow
Network controllers (NCs) are devices that are capable of converting dynamic, spatially extended, and functionally specialized modules into a taskable goal-oriented group called ne…
A Harmonic Potential Field Approach for Joint Planning & Control of a Rigid, Separable Nonholonomic, Mobile Robot
Ahmad A. Masoud
The main objective of this paper is to provide a tool for performing path planning at the servo level of a mobile robot. The ability to perform, in a provably correct manner, such…
Modeling Cellular Networks with Full Duplex D2D Communication: A Stochastic Geometry Approach
Konpal Shaukat Ali, Hesham ElSawy, Mohamed-Slim Alouini
Full-duplex (FD) communication is optimistically promoted to double the spectral efficiency if sufficient self-interference cancellation (SIC) is achieved. However, this is not tru…
