Autonomous attitude using potential function method under control input saturation [PDF]

open access: yes, 2008
The potential function method has been used extensively in nonlinear control for the development of feedback laws which result in global asymptotic stability for a certain prescribed operating point of the closed-loop system.

On the Potential of Function-Behavior-State (FBS) Methodology for the Integration of Modeling Tools [PDF]

open access: yes, 2009
Organised by: Cranfield UniversityCurrent mechatronic products tend to be very complex systems. A design team is necessary to develop such products, and appropriate modeling and design support tools are essential to aid the design team.

Small spacecraft formation-flying using potential functions [PDF]

open access: yes, 2008
A group of small spacecraft able to change its orbital formation through using the potential function is discussed. Spacecraft shapes, sizes and manoeuvering capabilities in general are not identical.

Mitochondrial Function as a Potential Tool for Assessing Function, Quality and Adulteration in Medicinal Herbal Teas [PDF]

open access: yes, 2021
Quality control has been a significant issue in herbal medicine since herbs became widely used to heal. With the advent of modern technologies, evaluating the quality of medicinal herbs has become more sophisticated but so have the methods of ...

Flow in Fractured Porous Media Modeled in Closed-Form: Augmentation of Prior Solution and Side-Stepping Inconvenient Branch Cut Locations

open access: yesFluids, 2020
Carefully chosen complex variable formulations can solve flow in fractured porous media. Such a calculus approach is attractive, because the gridless method allows for fast, high-resolution model results.

The internal rotation in 1,1,1-trifluorinealkanes [PDF]

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2017
14 potential functions V(φ) of the internal rotations around the C — C bonds in molecules of 1,1,1-trifluorine alkanes CF3 — (CH2)n — CH3, where 1 ≤ n ≤ 4, were obtained and approximated by Fourier series.

Spherical potential functional theory [PDF]

open access: yesThe Journal of Chemical Physics, 2021
According to a recent theorem of Theophilou [J. Chem. Phys. 149, 074104 (2018)], a set of spherically symmetric densities determines uniquely the external potential in molecules and solids. This theorem leads to a fresh formulation of density functional theory.

Numerical Solutions of Inverse Nodal Problems for a Boundary Value Problem

open access: yesMathematics, 2022
In this paper, we study inverse nodal problems for a boundary value problem. A uniqueness result for the potential function and a reconstruction method are obtained.

Potential Functions and Conservative Estimating Functions

open access: yesThe Annals of Statistics, 1994
The authors point out that the quasi-score function introduced by \textit{R. W. M. Wedderburn} [see e.g. Biometrika 61, 439-447 (1974; Zbl 0292.62050)] and \textit{P. McCullagh} [see e.g. Ann. Stat. 11, 59-67 (1983; Zbl 0507.62025)] does not inherit all important properties of the likelihood score function. Therefore they develop a method of projecting
