Generalized code index modulation and spatial modulation for high rate and energy-efficient MIMO systems on rayleigh block-fading channel
(IEEE, 2021)
In this article, a high data rate and energy-efficient multiple-input multiple-output transmission scheme is considered by combining two popular and rational modulation techniques: spatial modulation (SM) and code index ...
A numerical study on the estimation of liquefaction-induced free-field settlements by using PM4Sand model
(Korean Society of Civil Engineers, 2021)
The present paper treats the estimation of liquefaction-induced, free-field settlements using two-dimensional, fully coupled, finite element (FE) analyses. The PM4Sand model is used to simulate the liquefaction behavior ...
Modeling of complex gray cast iron open-cell foams revealing insights on failure and deformation on different hierarchical length-scales
(Wiley-VCH, 2021)
Open-cell gray cast iron foams are a class of porous materials of increasing interest, with great potential to be used in energy damping applications and for sound isolation. We created finite element (FE) models from 3D ...
An experimental study on the heat transfer and wettability characteristics of micro-structured surfaces during water vapor condensation under different pressure conditions

In this study, condensation characteristics of water vapor on micro-structured surfaces at different pressures and subcooling temperature has been investigated experimentally. This work represents a basic study in order ...
Cooperative quadrature spatial modulation with Euclidean distance and capacity optimized antenna selection
(Wiley, 2021)
In this study, new cooperative-quadrature spatial modulation techniques based on Euclidean distance and capacity optimized antenna selection techniques (EDAS-CQSM and COAS-CQSM) are proposed for cooperative communication ...
Finite element-based coefficient of lateral earth pressure for cohesionless soil
(American Society of Civil Engineers, 2021)
In addition to various factors, the magnitude of lateral earth pressure depends on the direction and amount of the wall rotation. The current literature presents several expressions to calculate lateral earth pressure that ...
Observability, controllability and stability analysis of discrete time engineering dynamic systems by means of Lagrangian, Hamiltonian and dissipative functions in discrete forms
