Fast Methods of Coverage Evaluation for Tradespace Analysis of Constellations

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Simulation of distributed space missions (DSMs) for the purpose of phase-A mission design studies and general tradespace analysis is computationally challenging owing to the necessity of evaluating thousands of architecture options.

Fast Switch and Spline Function Inversion Algorithm with Multistep Optimization and k-Vector Search for Solving Kepler’s Equation in Celestial Mechanics

open access: yesMathematics, 2020
Obtaining the inverse of a nonlinear monotonic function f(x) over a given interval is a common problem in pure and applied mathematics, the most famous example being Kepler’s description of orbital motion in the two-body approximation.

Orbital angular momentum of the spiral beams [PDF]

open access: yesКомпьютерная оптика, 2019
At first sight, any rotation generates some angular momentum (it is true for a solid body). But these characteristics (rotation and orbital angular momentum) are rather different for optics and mechanics.

Coulomb Problem for Classical Spinning Particles

open access: yesUniverse, 2023
We consider the motion of a weakly relativistic charged particle with an arbitrary spin in central potential e/r in terms of classical mechanics. We show that the spin–orbital interaction causes the precession of the plane of orbit around the vector of ...

A quantitative evaluation of computational methods to accelerate the study of alloxazine-derived electroactive compounds for energy storage

open access: yesScientific Reports, 2021
Alloxazines are a promising class of organic electroactive compounds for application in aqueous redox flow batteries (ARFBs), whose redox properties need to be tuned further for higher performance.

A Study on Orbital Mechanics [PDF]

open access: yesInternational Journal of Trend in Scientific Research and Development, 2018
Space craft to solar system bodies must deal with multiple deviations under the in uence of gravity. The motion of satellite in one of the types of conic section strongly depends upon escape velocity. The goal of this paper is to nd the trajectory of satellite by analysing orbits eccentricity and or bital parameters.

Developing a New Explicit Guidance Method for the Trajectory Correction of Sub-Orbital Modules [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2013
This paper presents an explicit guidance method which could be used in the problems of orbit correction for sub-orbital modules. This method is based on solving the Lambert problem.

Majorana stellar representation of twisted photons

open access: yesPhysical Review Research, 2023
Majorana stellar representation, which visualizes a quantum spin as points on the Bloch sphere, allows quantum mechanics to accommodate the concept of trajectory, the hallmark of classical physics. We extend this notion to the discrete cylinder, which is

State-Dependent Molecular Dynamics

open access: yesMolecules, 2014
This paper proposes a new mixed quantum mechanics (QM)—molecular mechanics (MM) approach, where MM is replaced by quantum Hamilton mechanics (QHM), which inherits the modeling capability of MM, while preserving the state-dependent nature of QM.

Bound State Solution of Dirac Equation for Generalized Pöschl-Teller plus Trigomometric Pöschl-Teller Non- Central Potential Using SUSY Quantum Mechanics

open access: yesJournal of Mathematical and Fundamental Sciences, 2014
The bound state solution of the Dirac equation for generalized PöschlTeller and trigonometric Pöschl-Teller non-central potentials was obtained using SUSY quantum mechanics and the idea of shape invariance potential.
