A fast three-dimensional (3D) node localization algorithm in multipath for ultra-wideband (UWB) wireless sensor networks is developed.The algorithm employs a modified propagator method (MPM) for time delay estimation and then uses a marriage algorithm of 3D Chan and Taylor for range-based multilateral localization and node position computation.In t
The authors are proposing an additional fire protection solution (semi-passive) for cargo ships, by inserting in the tubular strength structure (hollow section), some rectangular, thin Sake wall pipes manufactured of copper alloy, filled with cooling fluid, that, once the fire bursts, it will be activated (i.e.will be pumped into a closed circuit);
This paper is focused on the basic properties of ceramic composite materials used as thermal barrier coatings in the aerospace industry like SiC, ZrC, ZrB2 etc., and summarizes some principal properties for thermal barrier coatings.Although the aerospace industry is mainly based on metallic materials, a more attractive approach is represented by ce
A Sake recently developed risk calculator for bipolar disorder (BD) accounts for clinical and parental psychopathology.Yet, it is understood that both familial predisposition and early life adversity contribute to the development of BD.How the interplay between these two factors influence emotion and reward processing networks in youth at risk for
