Underwater Source Localization Using TDOA and FDOA Measurements With Unknown Propagation Speed and Sensor Parameter Errors

open access: yesIEEE Access, 2018
Underwater source localization problems are complicated and challenging: 1) the sound propagation speed is often unknown and the unpredictable ocean current might lead to the uncertainties of sensor parameters (i.e., position and velocity); 2) the ...

An Algebraic Condition for the Exponential Stability of an Upwind Difference Scheme for Hyperbolic Systems

open access: yesСовременная математика: Фундаментальные направления, 2022
In the paper, we investigate the question of obtaining the algebraic condition for the exponential stability of the numerical solution of the upwind difference scheme for the mixed problem posed for onedimensional symmetric t-hyperbolic systems with ...

An Analysis of Fifth and Sixth Graders' Algebraic Thinking about Reverse Fraction Problems

open access: yesJournal of Educational Research in Mathematics, 2020
In light of a growing emphasis on the relationship between fractional knowledge and algebraic thinking, the purpose of this study was to compare algebraic thinking about reverse fraction problems between fifth graders who had not been taught fraction ...

Algebraic solution to a constrained rectilinear minimax location problem on the plane [PDF]

open access: yes2011 International Conference on Multimedia Technology, 2011
We consider a constrained minimax single facility location problem on the plane with rectilinear distance. The feasible set of location points is restricted to rectangles with sides oriented at a 45 degrees angle to the axes of Cartesian coordinates.

Epigenetic pacemaker: closed form algebraic solutions [PDF]

open access: yesBMC Genomics, 2020
AbstractBackgroundDNA methylation is widely used as a biomarker in crucial medical applications as well as for human age prediction of very high accuracy. This biomarker is based on the methylation status of several hundred CpG sites. In a recent line of publications we have adapted a versatile concept from evolutionary biology - the Universal ...

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.
