The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...

The aim of the present experience was to evaluate the harvesting systems on the basis of trash content of raw material and the losses of millable cane, as a consequence of the harvesting operation. The analysed harvesting alternatives include differences in mechanical, semi-mechanical and manual systems and they have been evaluated in plots of 960 m2 of a same uniform sugar cane field, the test...

In this paper, we analyze and demonstrate a novel rotational energy harvesting generator using gravitational torque. The electro-mechanical behavior of the generator is presented, alongside experimental results from an implementation based on a conventional DC motor. The off-axis performance is also modeled. Designs for adaptive power processing circuitry for optimal power harvesting are presen...

This research aims to provide a unique perspective on energy harvesting from ear canal dynamic motion that can be used to power electronic in-ear devices. Two micro-power generators are presented: one of them has a miniature hydro-electromagnetic core and another one is composed of a micro piezo film sheet in shape of a ring. The experimental results will show that 1.2μW and 0.2μW could be succ...

The idea that quantum-mechanical phenomena can play nontrivial roles in biology has fascinated researchers for a century. Here we review some examples of such effects, including light-harvesting in photosynthesis, vision, electronand proton-tunneling, olfactory sensing, and magnetoreception. We examine how experimental tests have aided this field in recent years and discuss the importance of de...
