Mechanized harvesting of coffee in the crop's first harvest has restrictions on its use. There are assumptions that this type of harvesting can increase damage to plants and increase the amount of coffee falling on the ...

Performing more than one operation of coffee harvester can increase fruit harvest efficiency by minimizing the amount of remaining plants and the need for manual transfer. This manual harvest makes often more expensive the ...

Information about the capacity of the operation, harvest efficiency and performance of the harvester are of great importance in the management of agricultural mechanized systems, assisting in the decisions to be taken by ...

Sugarcane cultivation is important for the economy of many countries, particularly for Brazil. This plant has been used to produce sugar, ethanol, second generation ethanol, fertilizers, as well as bioelectricity. Due to ...

The use of adapted harvesters for harvesting first-crop coffee requires a lower cost and exhibits a higher efficiency than manual harvesting. In view of this, the present study aimed to analyze the operational cost of ...

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 ...

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 ...

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 ...

Dynamics of a non-linear energy harvesting is affected by excitation source and to explore efficiency it is necessary to understand which region offers more energy and the influence of a forced periodic vibration related ...
