A two-point-Padé-approximant-based method for bounding some trigonometric functions

open access: yesJournal of Inequalities and Applications, 2018
Inequalities are frequently used for solving practical engineering problem. There are two key issues of bounding inequalities; one is to find the bounds, and the other is to prove the bounds.

New inequalities between the inverse hyperbolic tangent and the analogue for corresponding functions

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we present new inequalities which reveal further relationship for both the inverse tangent function arctan ( x ) $\arctan (x)$ and the inverse hyperbolic function arctanh ( x ) $\operatorname{arctanh}(x)$ .

Optimization of the Two Fishermen’s Profits Exploiting Three Competing Species Where Prices Depend on Harvest

open access: yesInternational Journal of Differential Equations, 2017
Bioeconomic modeling of the exploitation of biological resources such as fisheries has gained importance in recent years. In this work we propose to define and study a bioeconomic equilibrium model for two fishermen who catch three species taking into ...

Acoustic modeling using the digital waveguide mesh [PDF]

open access: yes, 2007
The digital waveguide mesh has been an active area of music acoustics research for over ten years. Although founded in 1-D digital waveguide modeling, the principles on which it is based are not new to researchers grounded in numerical simulation, FDTD ...

The Impact of Price on the Profits of Fishermen Exploiting Tritrophic Prey-Predator Fish Populations

open access: yesInternational Journal of Differential Equations, 2018
We define and study a tritrophic bioeconomic model of Lotka-Volterra with a prey, middle predator, and top predator populations. These fish populations are exploited by two fishermen.

Models, Simulations, and Experiments [PDF]

open access: yes, 2002
I discuss the difference between models, simulations, and experiments from an epistemological and an ontological perspective. I first distinguish between “static” models (like a map) and “dynamic” models endowed with the capacity to generate processes. Only the latter can be used to simulate.

Sharper bounds and new proofs of the exponential function with cotangent

open access: yesAIMS Mathematics, 2020
This paper provides a Páde interpolation based method for finding improved bounds for the exponential function with cotangent. In principle, it can recover many results in prevailing methods.

Disruptions to shared mental models from poor quality of service in collaborative virtual environments

open access: yesScientific Reports, 2021
Collaborative virtual environments are being used in various applications ranging from online games to complex team training scenarios. The key to the success of such environments is the ability of the participants to form a shared mental model of the ...
