This work analyzes the influence of displacement rate on tensile properties and fracture parameters, determined through a viscoelastic Fracture Mechanics approach, carboxyl-terminated polybutadiene (CTPB) based solid composite propellants. Low medium rates attained in an electromechanical testing machine were inspected. From true stress-true pseudo strain curves, Young’s modulus was not influen...

The axion is a hypothetical particle which candidate for cold dark matter. Haloscope experiments directly search these particles in strong magnetic fields with RF cavities as detectors. Relic Axion Detector Exploratory Setup (RADES) at CERN particular searching matter mass range above 30 <t...

Highly optimized tolerance (HOT) is a mechanism that relates evolving structure to power laws in interconnected systems. HOT systems arise where design and evolution create complex systems sharing common features, including (1) high efficiency, performance, and robustness to designed-for uncertainties, (2) hypersensitivity to design flaws and unanticipated perturbations, (3) nongeneric, special...

In this paper we present a new Analysis/Synthesis method named SINOLA, which benefits from both sinusoidal additive model and OLA/PSOLA method, and which allows adequate processing according to the inherent local characteristics of the signal. All the parameters of the models are derived at the same time from spectrum analysis. We propose an analytical formulation of a Complex Short-Time Spectr...

The celebrated Expected Shortfall (ES) optimization formula implies that ES at a fixed probability level is the minimum of linear real function plus scaled mean excess function. We establish reverse formula, which says any threshold maximum an curve minus Despite being simple result, this reveals elegant symmetries between and curve, as well their optimizers. closely related to Fenchel-Legendre...

Through the simulation analysis of settlement and deformation law surface buildings caused by construction biased tunnel, following points are obtained: (1) The Peak formula is revised, influence range tunnel predicted based on formula. (2) It concluded that when biased, position maximum ground generally in a parallel area 0.5 times buried depth from center line tunnel. (3) double-layer verific...
