Implicit Central Difference Approximations of Averaged Dynamics of Highly Oscillatory Systems With Applications to Direct Optimal Control

Optimal Control Applications and Methods, EarlyView.
Trajectory optimization of highly oscillatory systems can require huge computational efforts if the horizon of the problem is much larger than the duration of a single cycle. To alleviate this effort, stroboscopic averaging methods can be used, which utilize local single‐cycle simulations of the oscillatory dynamics, to then approximate and integrate ...

Modeling‐based characterization for thermal expansion and chemical shrinkage of highly viscous epoxy resin with thermoplastic additives under the curing condition

Polymer Composites, EarlyView.
The modeling‐based method for characterizing the coefficients of thermal expansion and chemical shrinkage of the BA9916 resin. Abstract The present investigation introduced an indirect approach to accurately characterize thermal expansion and chemical shrinkage coefficients of the BA9916 resin, which is a thermoset epoxy resin with thermoplastic ...

Impregnation and saturation analysis of microwave‐preheated reactive resin in liquid composite molding

Polymer Composites, EarlyView.
Analysis of the improvements of impregnating and saturating resin flows in microwave‐preheated liquid composite molding. Abstract In liquid composite molding processes, resin preheating is a strategy to reduce the viscosity, which consequently improves resin flow and reduces impregnation time. However, the provision of heat to thermoset systems must be

The use of elliptic curves in cryptography

, 2007
The use of elliptic curves in cryptography was suggested independently by Neal Koblitz and Victor Miller in 1985. Being a relatively new field, there is still a lot of ongoing research on the subject, but elliptic curve cryptography, or ECC for short, has already been implemented in real-life applications.

Wakesurfing, Wakeboarding, and Waterskiing: A Comparison of Wake Characteristics

River Research and Applications, EarlyView.
ABSTRACT Waterskiing has been a commonplace and generally well‐accepted activity on inland waterways for many decades. More recently, there has been a significant increase in wakeboarding and wakesurfing, with the latter relying heavily upon “enhanced” boat wake.

Automated extraction of right whale morphometric data from drone aerial photographs

Remote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...
