Polyphase Mid‐Latitude Glaciation on Mars: Chronology of the Formation of Superposed Glacier‐Like Forms from Crater‐Count Dating

open access: yesJournal of Geophysical Research: Planets, Volume 125, Issue 2, February 2020., 2020
Abstract Reconstructing Mars's glacial history informs understanding of its physical environment and past climate. The known distribution of viscous flow features (VFFs) containing water ice suggests that its mid‐latitudes were glaciated during the Late Amazonian period (the last several hundred million years).

Thévenin Equivalent Parameter Adaptive Robust Estimation Considering the Erroneous Measurements of PMU

open access: yesEnergies, 2020
Parameter estimation based on the measurement data of the phasor measurement unit (PMU) is an important approach for identifying the Thévenin equivalent parameters (TEPs) of power systems. However, in the process of acquiring or transmitting data in PMU,

A Method for Parameter Identification of Combined Integrating Systems

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This manuscript presents a novel structure of combined integration in the process industry and proposes an efficient method for identifying its parameters. Combined integrating processes are delay‐time processes that widely exist in the industry. Conventional identification methods have a low‐identification accuracy, a large vibration amplitude of the ...

An Improved Recursive Total Least Squares Estimation of Capacity for Electric Vehicle Lithium‐Iron Phosphate Batteries

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
A battery’s capacity is an important indicator of its state of health and determines the maximum cruising range of electric vehicles. It is also a crucial piece of information for helping improve state of charge (SOC) estimation, health prognosis, and other related tasks in the battery management system (BMS).
