Tomato recognition under complex environment by Improving SSD model
In order to improve the accuracy of tomato-picking robots’ recognition in complex environments, a tomato recognition method based on an improved SSD model was proposed. Based on the traditional SSD (Single Shot Multi-Box Detector) network model, an RFB (Receptive Field Block) module was added and the loss function was improved by adding repulsion loss to construct a network model for tomato fruit recognition in complex environments. The improved SSD model was tested with a self-made dataset, and a comparison test was conducted for tomatoes under different shade on sunny and cloudy days. The test results showed that the differences between the two algorithms were compared and analyzed with F1 as the evaluation value. Test results showed that the F1 values for single-fruit shade and multi-fruit shade were 87.3% and 85.6% on sunny days while the figure for leaf shade and root-stock shade were 83.6% and 89% respectively, increasing by 7%, 4% and 6%, 6% compared with the traditional SSD model. On cloudy days, the F1 values for the same four types of shades reached 79%, 79.6%, 78.3% and 80.3% respectively, rising by 2%,1.3% and 4.3% 5.7%. These results proved that the network could realize the accurate detection of tomato fruits in complex environments and provide a new method for testing agricultural robots for picking tomatoes.
Theoretical research into force interaction between vibrational lifting tool and root
When cultivated roots are lifted from the soil with the use of vibrational lifting tools, damage to their bodies is inflicted, in particular, they are broken off at the points of contact with the tool. The problem is especially pronounced in the case, when the root bodies sit in dry and firm soil, which results in the impact contact between the digging shares of the lifting tool and the root body. The aim of the present research is to determine and validate the rational design and kinematic parameters of the vibrational lifting tool for its force interaction with the root, when lifting the latter from the soil, under the condition of excluding damage to it. As a result of the carried out transformations, analytical expressions have been obtained for determining the impact impulse as well as the maximum permissible frequency of the tool’s oscillations and its mass reduced to the point of impact under the condition of not damaging the root. The results of the research provide for determining the rational parameters of the vibrational lifting tool. The tool oscillation frequency values that ensure the minimum root damage and loss rates and are appropriate for practical use in the operation of real root harvesters have been recommended. In the context of the design, kinematic and process parameters incidental to the existing root harvesters, the above-mentioned oscillation frequencies of the vibrational lifting tool can vary within the range of 8.0-21.2 Hz.
Study of drought in Haryana on the basis of drought indices
Drought is one of the most disastrous phenomenon as it inflicts untold numerous miseries on crop production and human societies. Haryana state lies in Trans-Gangetic plain and lies between 27⁰ 39’ N to 30⁰ 55’ N latitude and 74⁰ 27’ E to 77⁰ 36’ E longitude with an area of 44,212 km2 i.e. 1.3 % of the total area of the country. The study was carried out in the Department of Agricultural Meteorology, CCS HAU Hisar. The aim of study was to find out the frequency of drought in Haryana during kharif season of 21 districts, rainfall data were collected from India Meteorological Department for a period of 1987 to 2016. To identify the drought year’s two drought indices i.e. SPI and rainfall deviation from normal as given by IMD were used. On the basis of SPI values Ambala and Mewat in eastern zone and Fatehabad and Rewari in western zone are more prone to moderate drought, whereas Sonipat and Hisar has more chances to experience severe drought based on their past study. Kurukshetra and Kaithal seems to be safer in terms of their proneness to sever drought as they never experienced SPI based severe drought condition during the study period. Another criteria i.e. IMD’s rainfall deviation criteria of drought frequency reflected that the districts Sonipat, Bhiwani and Rewari have more tendency of getting moderate drought as compared to other districts and Kurukshetra and Kaithal in case of severe drought. In eastern zone of Haryana majority of area was under no drought conditions on the basis of both indices. As drought category is concerned the IMD criterion for drought is more sensitive to ‘Moderate’ and ‘Severe’ droughts and the SPI found more sensitive to ‘No drought’ conditions.
Effect of Dietary Iron on Growth and Survival Rate of Snubnose Pompano Trachinotus blochii (Lacepède, 1801)
Iron is the most essential trace element for the physiological and biochemical functions of fish. Iron can be absorbed from the diet as well as the surrounding water, but its uptake by fish gills is relatively low, and its major needs may be from the digestive tract. This study examined the influence of iron added to food on the growth and survival rate of snubnose pompano Trachinotus blochii. The fishes (initial length 7.51±0.39 cm, initial weight 72.00±3.06 g) were treated in cages (1 x 1 x 1 m) at the density of 30 fishes for each cage. Five levels of iron (0 - control, 30, 60, 90, 120 và 150 mg Fe/kg dry feed) were supplemented to control the diet and to feed the fishes for 8 weeks. Results indicated that the level of 90 mg Fe/kg dry feed was an appropriate dose for the growth rate of snubnose pompano. However, the addition of iron to the feed might not affect their survival rate.
Effects of different supplemental levels of whey protein on the properties and structure of millet–wheat mixed flour dough
In this study, the effects of whey protein on the macro- and microstructural quality of millet noodles and the underlying action rule were evaluated. The effects of different proportions of whey protein (2%, 4%, 6%, 8%, and 10%) on the farinograph properties, stretching properties, cooking quality, textural properties, and sensory quality of millet noodles were analyzed and compared using a farinograph and a texture meter and via Fourier transform infrared spectroscopy and scanning electron microscopy. Moreover, the effects of whey protein supplementation on the sulfhydryl content, gluten formation, and microstructure of millet noodles were investigated. Results showed that the addition of whey protein improved the farinograph properties of the dough, reduced dough hardness, and increased the maximum tensile force of the noodles. The addition of whey protein increased the content of free sulfhydryl and glutenin macropolymer of millet noodles, changed the secondary structure of protein in the original noodles, and promoted the formation of a uniform and continuous microstructure of noodles. Therefore, the addition of whey protein can improve the quality of noodles to some extent.
