Non-ideal excitation approach for piezoelectric vibration based energy harvesting
(2014-01-01)
Common solution for energy harvester device is project design according harmonic excitation around natural frequency matching excitation source. Environment vibration is random and wide band causing short time of resonance ...
LINEAR MATRIX INEQUALITIES CONTROL DRIVEN FOR NON-IDEAL POWER SOURCE ENERGY HARVESTING
(Polish Soc Theoretical & Applied Mechanics, 2015-01-01)
The dynamic model of a linear energy harvester excited by a non-ideal power source is coupled to a controller to maximum vibration adjustment. Numerical analysis is taken to evaluate the energy harvested keeping the vibration ...
Agronomic traits and grains losses in the corn mechanical harvesting as a function of cover crop management
(Univ Fed Grande Dourados, 2015-01-01)
It is very important to know the types of cover crop managements before starting the deployment of the main crop, because these can influence the grain yield as well as the mechanical harvesting process, occurring losses ...
Analysis of bistable and chaotic piezoelectric energy harvesting device coupled with diode bridge rectifier
(2015-01-01)
Vibration energy harvesting has greatly expanded over the last few years. While linear vibration-based energy harvesting has received considerable attention in the literature, some current research is focused on the concept ...
Economic analysis for sizing of sugarcane (Saccharum spp.) mechanized harvesting
(2014-01-01)
Sugarcane has a significant role on Brazilian agribusiness economy. The harvesting cane is considered as one of the most important operations of the process for it has to attend the raw material demanded by the sugar mill ...

The times, movements and operational efficiency of mechanized coffee harvesting in sloped areas
(Public Library Science, 2019-05-28)
Coffee farms have been adopting the microterraces system, a technique that reduces the effect of the slope by moving the soil between the crop lines. In this way, all the mechanized operations can be carried out normally, ...
CAN BASAL CUTTING BLADE WEAR AFFECT SUGARCANE REGROWTH?
(Soc Brasil Engenharia Agricola, 2020-01-01)
Sugarcane harvester cutting blade wear increases ratoon damages and losses, impairing sugarcane regrowth. This study aimed to evaluate the quality of basal cut using ratoon damage and loss indexes and correlating them with ...
Implementation of an energy harvesting system by piezoelectric elements exploiting the human footsteps
(Institute of Electrical and Electronics Engineers Inc., 2017)
The fundamental idea of this research work is to present an approach to energy harvesting, which basically uses piezoelectric technology and is implemented in a shoe. It takes advantage of the energy that the user waste ...
