The Load Spectrum Compilation of Engine Vibration Fatigue Based on Frequency Rain-flow Counting Method

open access: yesHangkong gongcheng jinzhan, 2021
The traditional rain-flow counting method is suitable for conventional fatigue load calculation, and cannot retain the frequency information of vibration fatigue. Frequency is very important for vibration fatigue.

Thermal Fluctuations: Modes versus the Continuum [PDF]

open access: yes, 2003
The thermal fluctuation spectrum of the signal received on a patch electrode is examined and it is shown that the spectrum shows both the modes of the plasma and a continuous spectrum related to the independent-particle motions of plasma electrons. Modes

A three-dimensional finite element model of maximal grip loading in the human wrist [PDF]

open access: yes, 2009
The aim of this work was to create an anatomically accurate three-dimensional finite element model of the wrist, applying subject-specific loading and quantifying the internal load transfer through the joint during maximal grip.

Fatigue Models Based on Real Load Spectra and Corrected S-N Curve for Estimating the Residual Service Life of the Remanufactured Excavator Beam

open access: yesMetals, 2021
To more accurately predict the residual fatigue cycles and estimate the service life of the remanufactured excavator, the fatigue models integrating the corrected S-N curve, the RFC algorithm, the FEA model, and the mechanism dynamic model are ...

No evidence for inhibitory deficits or altered reward processing in ADHD: data from a new integrated incentive delay go/no-go task [PDF]

open access: yes, 2016
Objective: Cognitive and motivational factors differentially affect individuals with mental health problems such as ADHD. Here we introduce a new task to disentangle the relative contribution of inhibitory control and reward anticipation on task ...

Load Balancing via Random Local Search in Closed and Open systems [PDF]

open access: yes, 2010
In this paper, we analyze the performance of random load resampling and migration strategies in parallel server systems. Clients initially attach to an arbitrary server, but may switch server independently at random instants of time in an attempt to ...
