( IEEE , 2023 , Article)We propose a fixed-wing unmanned aerial vehicles (UAV)-based millimeter wave (mmWave) backhaul architecture that is offered as a cost effective and easy to deploy solution, to connect a disaster or remote area to the nearest ... -
Performance Analysis of Modulating Retroreflector Array for UAV-Based FSO Links
( IEEE , 2023 , Article)In this work, we investigate the performance of free space optical (FSO) communication systems based on modulating retroreflector (MRR) array. In particular, we first characterize the MRR array-based FSO channel by taking ... -
Enabling Flexible Arial Backhaul Links for Post Disasters: A Design Using UAV Swarms and Distributed Charging Stations
( IEEE , 2024 , Article)In this article, our target is to design a permanent long backhaul link using unmanned aerial vehicle (UAV) relays and charge stations (CSs) to transfer data from the nearest core network to disaster area (DA). To this ... -
Performance Analysis of Two-Way Relaying in mmWave-Based Aerial Links
( IEEE , 2024 , Article)Two-Way Relaying (TWR) is an efficient relaying technique that doubles the spectral efficiency as compared to the traditional one-way relaying. As such, it has been nominated as a solution to extend the coverage of links ... -
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
( American Society of Mechanical Engineers (ASME) , 2014 , Conference Paper)The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ... -
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
( Taylor and Francis , 2012 , Article)Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ... -
Shear strength of geosynthetic composite systems for design of landfill liner and cover slopes
( Elsevier , 2011 , Article)Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test ... -
Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
( American Society of Civil Engineers (ASCE) , 2013 , Article)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
A technique for estimating permeability of a randomly fractured rock mass
( Springer Verlag , 2007 , Article)Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ... -
Geotechnical considerations on the design of piled rafts on rock
( Research Publishing Services , 2011 , Conference Paper)This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ... -
Factors influencing determination of shale classification indices and their correlation to mechanical properties
( Springer Verlag , 2006 , Article)The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ... -
Stability analysis and charts for slopes susceptible to translational failure
( Canadian Science Publishing , 2006 , Article)The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ... -
Numerical study on settlement of piled foundations on homogenous rock
( Taylor and Francis , 2014 , Conference Paper)Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ... -
Comparative study on the behavior of square foundations resting on confined sand
( Canadian Science Publishing , 2009 , Article)The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ... -
Two- and three-dimensional analyses of translational slides in soils with nonlinear failure envelopes
