Effect of the length of silicon nano-dot/wire on band gap
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2014 , Conference Paper)
We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ...
Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
Degraded Arid Soil Reclamation for Cotton Cultivation Using Organic Waste Amendments
(2024 , Conference Paper)
Qatar is one of the most fertilizer-dependent countries due to challenging soil and climatic conditions. The country strives toward self-sufficiency in agricultural production in alignment with the Qatar National Vision ...
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, ...
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 ...
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 ...
THz vs. FSO: An Outage Probability and Channel Capacity Performance Comparison Study
(
IEEE
, 2023 , Conference Paper)
The main subject of this work is to make a detailed comparison between the performance of free-space optical (FSO) and terahertz (THz) links under different conditions. To this end, we first perform a detailed modeling of ...
UAV Trajectory Optimization for Directional THz Links Using Deep Reinforcement Learning
(
IEEE
, 2023 , Conference Paper)
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) ...
A Switched-Capacitor Based Multilevel Inverter with Extendable Levels having Enhanced Voltage Gain for Renewable Energy Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
Various Switched-Capacitor based Multilevel Inverters (SCMLI) are suggested in literature. These converters can, however, provide fixed levels of ac output voltage. A higher number of renewable energy units must be linked ...
An Improved ANPC-based 7-level Inverter with Reduced Component and Low TSV for EV Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
The low dc-link voltage requirements of active-neutral-point-clamped (ANPC) inverters with voltage-gain capabilities make them attractive. The system's overall efficiency, reliability, and power density are improved by the ...
