Automatic estimation of the amount of trash, such as branches and leaves, collected by a mechanical citrus harvester during harvesting eliminates problems in the processing plants with handling diseased leaves and fruit. A machine vision system was developed to estimate the amount of trash collected by a citrus canopy shake and catch harvester by acquiring and analyzing the images of the harves...
Technical product harvesting (TEPHA) is a newly developing interdisciplinary approach in which bio-based production is investigated from a technical and ecological perspective. Society's demand for ecologically produced and sustainably operable goods is a key driver for the substitution of conventional materials like metals or plastics through bio-based alternatives. Technical product harvestin...
guilan province is the biggest hazelnut producer in iran. over 70% of hazelnut production cost is due to its manual harvesting. therefore, study on all aspects of its cultivation mechanization is necessary to sustain its production. this study focused on identifying factors that affect the development of hazelnut harvesting mechanization in guilan province, iran, using a three-round delphi tech...
Energy harvesting is a new promising research area for portable electronics. Portable electronic devices have been typically limited by the finite lifetime and size of the internal batteries. This has been a constant conflict and tradeoff between battery size and device capabilities. For instance, cardiac pacemaker lifespan is mostly limited by battery size, which occupies at least half the ava...
Segmentally structured disk triboelectric nanogenerator for harvesting rotational mechanical energy.
We introduce an innovative design of a disk triboelectric nanogenerator (TENG) with segmental structures for harvesting rotational mechanical energy. Based on a cyclic in-plane charge separation between the segments that have distinct triboelectric polarities, the disk TENG generates electricity with unique characteristics, which have been studied by conjunction of experimental results with fin...
