In order to best utilize the moisture, nutrients and solar radiation and for obtaining high seed yield of good quality, optimum time of sowing should be identified. The taste of sweet corn kernels is 25-30% sweeter than normal corn. At optimum market maturity, sweet corn will contain 5 to 6% sugar, 10 to 11% starch, 3% water-soluble polysaccharides, and 70% water. Sweet corn must be harvested during optimal maturity to obtain best eating quality, a finite capacity of vegetable processing facilities and steady demand for fresh produce necessitate all harvest period. Producers extend harvest by staggering planting dates and planting hybrids with different maturity dates. Factors influencing the productivity of sweet corn and maize are numerous and include environmental conditions, cultivars characteristics, soil management practices and plant population density Knowledge of sweet corn response to environmental conditions has led to improvements in crop production.
To realize the task of tomato string-picking manipulator under the guidance of the obtained visual information, a visual servo control system for a seven-degree-of-freedom picking manipulator was designed. The visual servo control system consists of a parallel binocular camera, a 7-DOF manipulator, and a control system. The PC was adopted as the host computer, and the host computer control interface was developed based on Matlab software, which was to collect and process the image information. A STM32F103 microcontroller was used as the slave computer, which send PWM wave to control the joint motors in the instruction of host computer. The experimental results show that the visual servo control system has a 90% success rate in picking the static target, and the average picking time is 18s.The success rate for dynamic targets is 83%, with an average picking time of 22s.
This article presents the results of a study on optimization of electrical discharge machining (EDM) when machining SS304 stainless steel cylindrical shaped parts. The objective function of the problem is the maximum material removal speed (MRS). An experiment has been designed and performed to solve this problem. In addition, the experimental design and result's analysis were carried out by applying the Taguchi method with the support of the Minitab R19 software. Besides, the influence of the input process parameters, including the pulse on time, the pulse off time, the servo current, and the servo voltage on the MRS was explored. Furthermore, the optimal inputs of the EDM process factors to achieve the maximum MRS have been proposed.
In this paper, a study on optimizing electrical discharge machining (EDM) when processing cylindrical shaped parts of stainless steel SS304 to achieve minimum surface roughness (SR) was introduced. To solve the optimization problem, an experiment was designed and performed. Besides, the Taguchi method in the Minitab R19 software was used to design the experiment and analyze the results. In addition, the influence of the input process parameters, including the pulse on time, the pulse off time, the servo current, and the servo voltage on SR was investigated. Furthermore, the optimal input factors of the EDM process for minimum SR were found.
The study was carried out in three markets of Imphal west district and two markets of Bishnupur district due to having the traditional knowledge of dry fermented fish predominantly a total of 120 respondents were randomly selected the fish marketing enterprise in these areas is slightly dominated by the females in the study area. The income range of 41.67 per cent of the business falls annually in the range of ₹ 3 to 7 lakhs. Total three marketing channels involves for transferring dry fermented fish to the ultimate consumers. The total marketing cost, marketing margin and the price spread was found to be highest in channel-I with ₹ 15, ₹ 65 and ₹ 80, respectively; out of the total 75.00 per cent sold of fish including dry fermented fish and 91.67 per cent of the marketers maintained that fish supply is very regular, while most of the respondents (90.00 per cent) found as an profitable venture. During the market conduct cent per cent of the respondents get information on market situation through personal contact, even the buyers shows that majority (61.67 per cent) arrived through haggling, whereas 55.00 per cent said prices were fixed by both the sellers and the agents. The constraints are transportation, lack of storage facilities, breakage / leakage of pots, presence of exploitative middlemen etc, It is recommended that local fish marketers should be organized into co-operative groups and government should adequately provide good market facilities to improve market efficiency to reduce the marketing cost.
