MECHANICAL OLIVE HARVESTING SYSTEMS [PDF]
Acta Horticulturae, 1999 Trunk or bough shakers for the mechanical harvesting of olives can be complemented by collecting equipment now available: the inverted umbrella and the rolling canvas catching frame. The performance of both is compared with the traditional method of collecting olives on a canvas layed manually under the tree, the fruit being detached by shakers.

Electrostrictive Polymers for Mechanical-to-Electrical Energy Harvesting [PDF]
, 2016 Research of electrostrictive polymers has generated new opportunities for harvesting energy from the surrounding environment and converting it into usable electrical energy. Piezoelectric ceramic based devices have long been used in energy harvesting for

Electrochemically driven mechanical energy harvesting [PDF]
Nature Communications, 2016 AbstractEfficient mechanical energy harvesters enable various wearable devices and auxiliary energy supply. Here we report a novel class of mechanical energy harvesters via stress–voltage coupling in electrochemically alloyed electrodes. The device consists of two identical Li-alloyed Si as electrodes, separated by electrolyte-soaked polymer membranes.

Mechanical harvesting of broilers
Poultry Science, 1998 At the end of the growout phase of broiler production essentially all broilers are caught and loaded into coops or cages entirely by hand. The catching of broilers remains one of the few aspects of broiler production not yet automated. Vacuum systems, permanent conveyors recessed in the floors of growout facilities, collecting mats, scoops, and self ...

Long-Term Evaluation of the Influence of Mechanical Pruning on Olive Growing [PDF]
, 2012 In Portugal, olive (Olea europaea L.) groves with the traditional tree density of around 100 trees ha -1, necessitate increasing pruning costs every year. As a result farmers tend to lengthen pruning intervals.

Mechanized Grape Harvest Efficiency [PDF]
Applied Sciences, 2021 Due to the low number of employees and the time limit in the field of grape harvesting, we focused in the presented article on evaluating the effectiveness of the deployment of an outboard grape harvester within the conditions of Slovak viticulture.

Active and reactive power in stochastic resonance for energy harvesting [PDF]
, 2015 A power allocation to active and reactive power in stochastic resonance is discussed for energy harvesting from mechanical noise. It is confirmed that active power can be increased at stochastic resonance, in the same way of the relationship between ...

Modelling the effect of actuator-like behavior in dielectric elastomer generators [PDF]
, 2015 Dielectric Elastomer Generators (DEGs) have been claimed as one promising technology for renewable mechanical to electrical energy harvesting, due to their lightweight, low cost and high energy density. Dielectric elastomers have a dual behavior, able to

Enhanced vibrational energy harvesting using non-linear stochastic resonance [PDF]
, 2008 Stochastic resonance has seen wide application in the physical sciences as a tool to understand weak signal amplification by noise. However, this apparently counter- intuitive phenomenon does not appear to have been exploited as a tool to enhance ...
