Statistical Mechanics of Vibration-Induced Compaction of Powders [PDF]

open access: yes, 1998
We propose a theory which describes the density relaxation of loosely packed, cohesionless granular material under mechanical tapping. Using the compactivity concept we develope a formalism of statistical mechanics which allows us to calculate the ...

Interaction between Additives in Metalworking Fluids under Difficult Cutting Conditions

open access: yesTribology Online, 2008
In order to investigate the interaction between additives in metalworking fluids under difficult cutting conditions, tapping tests were conducted under different metalworking conditions for metalworking fluids consisting of liquid paraffin added with ...

High intensity tapping regime in a frustrated lattice gas model of granular compaction

open access: yes, 2010
In the frame of a well established lattice gas model for granular compaction, we investigate the high intensity tapping regime where a pile expands significantly during external excitation.

Tapping Performance of Professional and Amateur Darbuka Players

open access: yesFrontiers in Psychology, 2022
Motor skills of professional musicians can be regarded as a model to investigate human skill acquisition after prolonged practice. Although rhythmic tapping skills of musicians such as drummers and pianists were investigated previously, the tapping ...

Depth Aware Finger Tapping on Virtual Displays

open access: yesACM SIGMOBILE International Conference on Mobile Systems, Applications, and Services, 2018
For AR/VR systems, tapping-in-the-air is a user-friendly solution for interactions. Most prior in-air tapping schemes use customized depth-cameras and therefore have the limitations of low accuracy and high latency.

Acute Effects of Cannabis Concentrate on Motor Control and Speed: Smartphone-Based Mobile Assessment

open access: yesFrontiers in Psychiatry, 2021
Background: The use of cannabis concentrate is dramatically rising and sparking major safety concerns. Cannabis concentrate contains tetrahydrocannabinol (THC) potencies up to 90%, yet there has been little research on motor impairment after concentrate ...

Quantification of Finger-Tapping Angle Based on Wearable Sensors

open access: yesItalian National Conference on Sensors, 2017
We propose a novel simple method for quantitative and qualitative finger-tapping assessment based on miniature inertial sensors (3D gyroscopes) placed on the thumb and index-finger.

The "double cut alternative" (DCA) tapping system: an innovative tapping system designed for Thai rubber smallholdings using high tapping frequency [PDF]

open access: yes, 2011
In Thailand, the continuous decrease in the size of rubber plantations has led to the general adoption of intensive tapping systems which may lead to over harvesting, high rates of tapping panel dryness (TPD), short life-cycles of the plantations, and ...

Modeling Accuracy and Variability of Motor Timing in Treated and Untreated Parkinson’s Disease and Healthy Controls [PDF]

open access: yes, 2011
Parkinson’s disease (PD) is characterized by difficulty with the timing of movements. Data collected using the synchronization–continuation paradigm, an established motor timing paradigm, have produced varying results but with most studies finding ...
