Zero forcing based sphere decoder for generalized spatial modulation systems
ETRI Journal, 2019 To reduce the number of radio frequency (RF) chains in multiple input multiple output (MIMO) systems, generalized spatial modulation (GSM) techniques have been proposed in the literature.

FULL-RATE SPACE-TIME BLOCK CODE FOR FOUR TRANSMIT ANTENNAS WITH LINEAR DECODING
Jordanian Journal of Computers and Information Technology, 2020 This paper proposes a new full-rate space-time block code for MIMO systems at four transmit antennas, which aims at minimizing the bit error rate with low-complexity decoding using ZF and MMSE linear detection techniques in Rayleigh fading channels ...

Leaky Forcing: A New Variation of Zero Forcing
, 2019 Zero forcing is a one-player game played on a graph. The player chooses some set of vertices to color, then iteratively applies a color change rule: If all but one of a colored vertex's neighbors are colored, color (i.e. "force") the remaining uncolored neighbor. Generally, the goal is to find the minimum number of vertices to initially color such that

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Zero Forcing Sets for Graphs [PDF]
, 2013 For any simple graph $G$ on $n$ vertices, the (positive semi-definite) minimum rank of $G$ is defined to be the smallest possible rank among all (positive semi-definite) real symmetric $n\times n$ matrices whose entry in position $(i,j)$, for $i\neq j$, is non-zero if $ij$ is an edge in $G$ and zero otherwise. Also, the (positive semi-definite) maximum

Advanced Engineering Materials, EarlyView.Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

On the power domination number of the Cartesian product of graphs
AKCE International Journal of Graphs and Combinatorics, 2019 We give a brief survey about the existing results on the power domination of the Cartesian product of graphs, and improve two of the results by determining the exact power domination numbers of two families of graphs, namely, the cylinder and the tori ...
