Heat exchange by radiation in the working space of high-temperature combustion chambers is the predominant type of heat exchange, depending both on the temperature of the flame and on its emissivity. As is known, a luminous flame differs from a non-luminous one in that it emits thermal energy not selectively within the CO 2 and H 2 O bands, but over the entire spectrum, including the visible region. Moreover, it is in the visible region of the glowing flame of natural gas that a significant amount of thermal energy is emitted. This is explained by the fact that the dispersed phase (soot), which arose during the decomposition of methane, contains particles of such sizes (0.05-0.2 microns), which are characterized by maximum radiation in the visible and near-infrared regions of the spectrum. Thus, the emissivity of a luminous flame is significantly higher than the emissivity of a non-luminous flame. This ability of the luminous flame is the reason for its use in diesel internal combustion engines (DICE).

“…According to (Alatyrev et al, 2020), the Chuvash state agricultural Academy in Russia designed a multivariate cabbage harvester system that helped farmers to harvest cabbages in the field. The robot had a cutting device that was in a position to cut the cabbage plants aligned longitudinal and transverse as it is moving, after cutting the cabbage head, they could be directed to the cloth of a conveyer belt at a joint with a climbing conveyor where a roller was used to load them into the containers accompanying the robotic machine after separate cabbage leaves from cabbage heads, and the leaves, unripe heads had to be off loaded at the end of the conveyer to the ground.…”

Citrus harvesting has been done manually for the past Sixty-Two (62) years in Eastern Uganda, where commercial citrus cultivation started in the 1960s. Farmers use employees to help in harvesting so that fruits can be picked on schedule. At this point, the hired harvesters gather in gardens and divide up the harvesting tasks among themselves. Some climb citrus trees to reach the ripe citrus fruits on the branches, while others gather fruits on the ground, pack them into sacks, and then transport the sacks of fruits to the required stores. Thereafter, a prototype was developed using a design science approach, and a field-oriented algorithm (FOC) was used to set power and torque during the programming of the actuators for speed regulations. After that, the validation process of the robot was determined by using a stopwatch such that to calculate the time it takes for the developed system to carry out the tasks successfully while in the field and the results showed that it picked up six citruses (6) fruits in five seconds (5 sec) from the ground per two (2) revolutions of the picking mechanism. Compared to hand harvesting, the prototype's storage capacity findings showed that it could only hold forty (40) citrus fruits, which were filled in 33.4 seconds, maximizing harvesting efficiency. And this was achieved by getting 6 citrus fruits collected per two revolutions divided by the 40 which is the maximum storage capacity that was determined after the robot loading for 6 rounds as shown below in the full load capacity = (40/6 = 6.67kgs), then during the study, the time it takes to load to full capacity = 6.67 * 5 = 33.4 seconds. Therefore, this research is highly recommended to citrus farmers in Soroti such that low labor, high quality, and less time are achieved by farmers during harvesting.
