Magnetic plucking applies the strategy of frequency up-conversion in inertial energy harvesting when the energy source, such as human motion, provides excitations with very low and irregular frequencies. In a typical implementation, a slower moving inertial mass magnetically plucks a piezoelectric cantilever beam which converts mechanical energy to electrical energy at a higher frequency. We ca...

This paper presents a signal processing technique for extracting the plucking point on a guitar string from an acoustically recorded signal. It also includes an original method for detecting the fingering point, based on the plucking point information.

Whisker plucking in developing and adult rats provides a convenient method of temporarily altering tactile input for the purposes of studying experience-dependent plasticity in the somatosensory cortex. Yet, a comprehensive examination of the effect of whisker plucking on the response properties of whisker follicle-innervating trigeminal ganglion (NVg) neurons is lacking. We used extracellular ...

The growth of hair from the mystacial vibrissal follicles of C3H mice and Wistar rats has been measured for up to seven cycles. Normally growth in length and thickness was regular and little affected by age or sex. Plucking vibrissae at any stage during the growing period was followed by the appearance of a new vibrissa 8-11 days later. Plucking when growth had ceased had no effect on the time ...

Work related musculoskeletal disorders are seen as an indicating parameter of occupational stress among the women workers engaged in tea leaf plucking operation. The hand plucking (no mechanized plucking is practiced in Assam) being a highly repetitive task requires forceful exertions to reach to the distant periphery of the tea bushes and mechanical compression (pressing against hard surfaces)...

This paper proposes a technique that estimates the locations along the string of the plucking event and the magnetic pickup of an electric guitar based on the autocorrelation of the spectral peaks. To improve accuracy, a method is introduced to flatten the spectrum before applying the autocorrelation function to the spectral peaks. The minimum mean squared error between the autocorrelation of t...

In a large-scale Swiss poultry abattoir, a microbiological process analysis of broiler carcasses was performed. At each selected process stage (scalding, plucking, evisceration, washing, and chilling), 90 carcasses from 30 flocks were sampled and examined for Campylobacter, Salmonella, Escherichia coli, Enterobacteriaceae, and extended-spectrum b-lactamases-producing Enterobacteriaceae. With re...
