Stochastic simulations are used to characterize the knotting distributions of random ring polymers confined in spheres of various radii. The approach is based on the use of multiple Markov chains and reweighting techniques, combined with effective strategies for simplifying the geometrical complexity of ring conformations without altering their knot type. By these means we extend previous studi...
The purpose of this work is to study and evaluate the limitations of using acoustic communications in the vicinity of artificial reefs. By placing hydrophones and transmitters in different strategic locations we have studied the performance of this technology in confined spaces. The ultimate goal of this work is to provide information for the proper design of acoustic communication systems to m...
Experimental investigation on the compressive behaviour of FRP-confined rectangular concrete columns
Abstract This paper presents a comprehensive experimental study on the behaviour of FRP-confined concrete in square and rectangular columns focuses some issues that might be addressed with view to improving predictive models. For this purpose, 31 prismatic specimens height 600 mm low- medium-strength (20–35 MPa) were tested under centred compression. The parameters studied aspect ratio between ...
