A method of measuring a movement, the method comprising the steps of: acquiring and digitizing both a first measurement voltage across the terminals of a first secondary winding and also a second measurement voltage across the terminals of a second secondary winding of an inductive movement sensor; multiplying the first measurement voltage by itself in order to obtain a first component of a crossed vector, multiplying the second measurement voltage by itself in order to obtain a second component of the crossed vector, and multiplying together the first measurement voltage and the second measurement voltage in order to obtain a third component of the crossed vector; applying the crossed vector as input to a lowpass filter in order to obtain a filtered vector, and estimating the movement from the components of the filtered vector.

Method for evaluating temperatures in active heave compensation ropes comprising the following steps: describe the geometry of ropes as composite structures obtained through assemblies of helical components in hierarchical levels: wires, strands and the rope itself; use a mechanical model of the strand that represents the material properties of each wire, under the assumption of linear elastic behavior; use a mechanical model of the rope that represents the combined action of tensile loads and imposed bending curvature; use a thermal model for the evaluation of the rope temperature increase (Ts) with respect to the ambient temperature, the thermal model comprising two main dissipation sources: the friction between strands or rope and a sheave and the friction between wires or between strands and compare rope temperature increase (Ts) obtained by the thermal model with a value of a predetermined temperature threshold.

Tailoring the emission spectra of a solar thermophotovoltaic emitter away from that of a blackbody, thereby minimizing transmission and thermalization loss in the energy receiver, is a viable approach to circumventing the Shockley-Queisser limit to single junction solar energy conversion. Embodiments allow for radically tuned selective thermal emission that leverages the interplay between two resonant phenomena in a simple planar structureabsorption in weakly-absorbing thin films and reflection in multi-layer dielectric stacks. A virtual screening approach is employed based on Pareto optimality to identify a small number of promising structures for a selective thermal emitter from a search space of millions, several of which approach the ideal values of a step-function selective thermal emitter
