A novel fluorinated monomer: Synthesis, characterization and ATRP of 5,6,7,8-tetrafluoronaphthalen-1-yl acrylate
(Elsevier Science Sa, 2021)
A new fluorinated naphthyl-acrylate based monomer was synthesized in three steps, namely the addition reaction of furan via Diels Alder cycloaddition reaction, acid catalyzed aromatization reaction and Schotten-Baumann ...
A COMPARATIVE STUDY ON CRASHWORTHINESS CHARACTERISTICS OF THIN-WALLED TUBES WITH FUNCTIONALLY GRADED THICKNESS AND VARIOUS CROSS-SECTIONAL GEOMETRIES
(Inegi-Inst Engenharia Mecanica E Gestao Industrial, 2016)
The present paper aims at investigating the effect of cross-section geometry on the crashworthiness characteristics of thin-walled aluminum tubes with functionally graded thickness (FGT). To achieve this aim, different ...
Weighted superposition attraction-repulsion (WSAR) algorithm for truss optimization with multiple frequency constraints
(Elsevier Science Inc, 2021)
Structural optimization of truss structures under multiple frequency constraints is a highly nonlinear and complex optimization problem with non-convex solution space. The optimization method used to solve mentioned problem ...
Optimal design of truss structures using weighted superposition attraction algorithm
(Springer, 2020)
In this paper, a recently developed swarm based metaheuristic algorithm called weighted superposition attraction (WSA) is implemented for sizing optimization of truss structures first time in literature. The WSA algorithm ...
2D and 3D Positioning Performance of UAV-Based Photogrammetry in Residential Regions
(2020)
UAVs (Unmanned Aerial Vehicles) are commonly used in photogrammetric observations in research fields like agriculture, archaeology, industry and construction of base maps. They present several advantages like low-cost ...
Abstract Korovkin theory in modular spaces in the sense of power series method
(2018)
In this paper, using the power series method we obtain an abstract Korovkin type approximation theorem for a sequence of positive linear operators dened on modular spaces.
