Carrier assignment algorithms for OFDM-based multi-carrier wireless networks with channel adaptation
(2008)We study carrier assignment in a single-cell multiuser OFDM multi-carrier system so as to satisfy user rate requirements with minimal resources. Different users experience different quality in different carriers due to ... -
The effects of FFF 3D printing parameters on energy consumption
(2022)Energy metrics in 3D-printing technologies are of major importance for sustainable manufacturing. The printing parameters (PP) affect the energy consumption remarkably and define the overall Energy Printing Consumption ... -
Key parameters controlling surface quality and dimensional accuracy: a critical review of FFF process
(2022)Fused filament fabrication (FFF) is an additive manufacturing process, which constructs physical items by fused melt material, selectively deposited layer-by-layer through a heated extrusion mechanism. Parameters’ selection ... -
Multi-parameter optimization of PLA/Coconut wood compound for Fused Filament Fabrication using Robust Design
(2022)This study investigates the effects of four variables during fused filament fabrication of organic biocompatible composite material, PLA with coconut flour, at the ultimate tensile strength (UTS), and elasticity module (E) ... -
A multi-parametric process evaluation of the mechanical response of PLA in FFF 3D printing
(2022)Polylactic acid (PLA) material in filament form can be 3D printed and form complex physical models by using a low-cost material extrusion mechanism in a process that is broadly known as fused filament fabrication (FFF). ...
