Gaussian Memory in Kinematic Matrix Theory for Self-Propellers [PDF]
, 2014 We extend the kinematic matrix ("kinematrix") formalism [Phys. Rev. E 89, 062304 (2014)], which via simple matrix algebra accesses ensemble properties of self-propellers influenced by uncorrelated noise, to treat Gaussian correlated noises. This extension brings into reach many real-world biological and biomimetic self-propellers for which inertia is ...

Analyze of multistage transfer orbit to reach the GEO orbit in a rotational symmetric gravitational field [PDF]
arXiv, 2005 Placing satellites in geostationary obital (GEO) is propellant exigeant. It requires large propellant consumption that will take a large part of the total mass. Hence the interest is reduce the mass of propellant loaded both in the rocket and the satellite. Both for improving selection of transfer orbits and propellant.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation
Advanced Functional Materials, EarlyView.This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Anaesthetic in the garb of a propellant
Indian Journal of Anaesthesia, 2015 Sir, Serendipity is the forerunner of scientific discoveries, and anaesthesia is no exception. Pressurised metered dose inhalers are routinely used for perioperative control of reactive airway disease. They can be mounted on the proximal aspect of the standard endotracheal tube (ETT) connector for direct drug delivery to the tracheobronchial tree by

Modelling Rocket System Performance Parameters
Academy Journal of Science and Engineering, 2022 What distinguishes the rocket system from airbreathing engines is that the rocket carries its own propellants, fuel and oxidants. The modern rocket was originally developed for ballistic missiles.
