An Improved Iterative Method to Obtain Optimal Monomer Addition Profiles in Copolymerizations

Macromolecular Reaction Engineering, EarlyView.
Controlling the chemical composition distribution of copolymers through optimal monomer addition profiles (OMAP) is of great importance for their properties. An improved semi‐empirical procedure is described to obtain OMAP on time basis that requires minimal knowledge of kinetics parameters and therefore is very suitable for monomers where most kinetic

Three Benefits of Using Nonlinear Compliance in Robotic Systems Performing Cyclic Tasks: Energy Efficiency, Control Robustness, and Gait Optimality

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Nonlinearity in parallel compliance can be exploited to improve the performance of locomotion systems in terms of (1) energy efficiency, (2) control robustness, and (3) gait optimality; that is, attaining energy efficiency across a set of motions. Thus far, the literature has investigated and validated only the first two benefits.

Expressions of Legendre polynomials through Bernoulli polynomials

Revista Técnica de la Facultad de Ingeniería, 2011
A formula for expanding Legendre polynomials in Bernoulli polynomials is considered. The relationship is established by using a formula of finite summation, obtained by applying the discrete orthogonal relation of the modified Lommel polynomials.

Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Characterization of Natural Rubber Latex With High‐Sensitivity, Diffusion‐Ordered, and Time Domain NMR

Polymer Engineering &Science, EarlyView.
Suspending old certainties, NMR now hints at a constant linear polyisoprene core whose corona morphs with pH tight, multilamellar in acidic latex, loose and hydrated after ammonia. ABSTRACT How reliable is our century‐old understanding of natural‐rubber latex (NRL) when examined through the lens of modern analytical techniques, such as nuclear magnetic
