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 ...

As an alternative solution for quick disaster recovery of backhaul/fronthaul links, in this paper, a dynamic unmanned aerial vehicles (UAV)-assisted heterogeneous (HetNet) network equipped with directional terahertz (THz) ...
Pointing Error Modeling of mmWave to THz High-Directional Antenna Arrays
(
IEEE
, 2022 , Article)
This letter focuses on providing an analytical framework for the quantification and evaluation of the pointing error at high-frequency millimeter wave (mmWave) and terahertz (THz) communication links. For this aim, we first ...
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 ...
