We recently characterized a unique material developed from root structure (Mycelium) of mushroom. Mycelium has a filamentous network structure with mechanics largely controlled by filament elasticity and branching, and network density. We report the morphological and mechanical characterization of mycelium. The monotonic mechanical behavior of the mycelium is non-linear both in tension and compression.

The 7th edition of the International Conference on Fatigue of Composites is going to be held in Vicenza (Italy) from 4th to 6th of July 2018. The conference is organized by the Department of Management and Engineering at the University of Padova, under the patronage of the European Society for Composite Materials, the Committee on Composite Materials of the Japan Society of Material Science, the Italian Association for Stress Analysis and the Italian Group of Fracture.

The phenomenon of gimbal lock rose in prominence during the time  of NASA's Apollo program. Inside the inertial measurement unit of the Apollo spacecraft was a stable (inertial) platform about which the spacecraft rotated. The hinged platform was suspended in two gimbals to give it three degrees of freedom. Its role was to give an accurate measure of the spacecraft's orientation. At a particular orientation of the spacecraft, the gimbals became coplanar and control torques became ineffective at stabilizing the platform.

We present a numerical method which exploits the biorthogonal interpolating wavelet family, and second-generation wavelets, to solve initial–boundary value problems on finite domains. Our predictor-corrector algorithm constructs a dynamically adaptive computational grid with significant data compression, and provides explicit error control. Error estimates are provided for the wavelet representation of functions, their derivatives, and the nonlinear product of functions.
