Subharmonic Resonance of Van Der Pol Oscillator with Fractional‐Order Derivative

open access: yesMathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
The subharmonic resonance of van der Pol (VDP) oscillator with fractional‐order derivative is studied by the averaging method. At first, the first‐order approximate solutions are obtained by the averaging method. Then the definitions of equivalent linear damping coefficient (ELDC) and equivalent linear stiffness coefficient (ELSC) for subharmonic ...

Perceived quality of BRDF models

open access: yesComputer Graphics Forum, Volume 44, Issue 4, July 2025.
Abstract Material appearance is commonly modeled with the Bidirectional Reflectance Distribution Functions (BRDFs), which need to trade accuracy for complexity and storage cost. To investigate the current practices of BRDF modeling, we collect the first high dynamic range stereoscopic video dataset that captures the perceived quality degradation with ...

Analysis of the Operational Characteristics and Performance Comparison of Steam Screw Pressure Matcher Based on Twin‐Screw Expander

open access: yesEnergy Science &Engineering, Volume 13, Issue 2, Page 626-642, February 2025.
In this study, a steam screw pressure matcher was proposed to solve the problem of mismatched pumping parameters and the user's required steam parameters. The efficiency of this pressure matcher was improved by 6.2%–12.4% compared to a conventional desuperheater.

The memory remains: Understanding collective memory in the digital age

open access: yesScience Advances, 2017
Disastrous events trigger our collective memory of past events to a surprising extent that can be modeled mathematically. Recently developed information communication technologies, particularly the Internet, have affected how we, both as individuals and ...
