The near-unity efficiency of energy transfer in photosynthesis makes photosynthetic light-harvesting complexes a promising avenue for developing new renewable energy technologies. Knowledge of the energy landscape of these complexes is essential in understanding their function, but its experimental determination has proven elusive. Here, the observation of quantum coherence using two-dimensiona...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...

In order to improve the operational performance of self-developed 4HLB-4 half-feed four-row peanut combine harvester, single-factor and multifactor field tests were conducted on key parameters affecting quality harvesting. The response surface methodology was used study effects forward speed, clamping height, picking roller rotational cleaning sieve vibrational frequency loss rate impurity rate...

The digging depth is an important factor affecting the mechanized garlic harvesting quality. At present, of combine harvester (GCH) adjusted manually, which leads to disadvantages such as slow response, poor accuracy, and being very dependent on operator’s experience. To solve this problem, paper proposes a machine vision-based automatic control system for original device. uses improved YOLOv5 ...

Data on the state of air environment at flax plants for a long period are given. It is noted that in studies conducted 30–70s last century, main harmful production factor working rooms mills dust. However, dust only one indicators sanitary and hygienic characte-ristics plants. Since level combine harvesting reached 90 % by 1979 quality products deteriorated, there was need comprehensive sanita-...

Interest in the development of stripper headers is growing owing to the excessive losses of combine harvesters and costs of manually harvesting for chickpeas. The design of a new concept can enhance the mechanized process for chickpea harvesting. A modified stripper platform was designed, in which passive fingers with V-shape slots remove the pods from the anchored plant. The floating platform ...

This work investigates the performance of a dual-hop energy harvesting-based fixed-gain amplify-and-forward relaying communication system, subject to fading impairments. We consider source node ( S) communicating with destination D), either directly or through fixed distant relay R), which harvests from its received signals and uses it amplify forward D. also maximal-ratio combining at D combin...

The research proposed a compact antenna integrated with dual-function solar cells to optimize internet of things (IoT) communication devices and energy harvesting. use electromagnetic elements as antennas energy-gathering in design is solution for wireless sensors simultaneously Radiation performance testing cell optical experiments were carried out test the ability collection. A double feed ri...

Aiming at the common problems of high working resistance, low soil disturbance, and rates missed extraction in operation carrot combine harvesters, a high-efficiency drag-reducing bionic soil-loosening shovel was designed this study. The physical parameters carrots were measured, using badger claw toe as prototype. wing structures designed. Based on EDEM discrete element simulation technology, ...
