Research and Test of Acoustic Signal Monitoring System of Fan Blade Based on BP Neural Network

Paper ID- AMA-07-09-2021-10695

Aiming at the difficult blade in daily maintenance of large-scale wind turbine, the sound signal of wind turbine blade can be detected by analyzing the non-contact fault of the blade. In this paper, a sound acquisition and transmission device is designed derived on stm32f103c8t6 single chip microcomputer. The device is arranged below the fan blade to collect the fan blade sound and transmit it to the PC through GPRS. The data is restored to the WAV format audio file on the PC. then LabVIEW software pre-processes the sound signal in the audio file and 1 / 6 octave processing to extract the acoustic characteristics of the blade, Finally, the BP neural network is trained and predicted by using the acoustic characteristics of fan blades in different states. The experimental results show that the training of BP neural network can be completed after 27 iterations, and the recognition rate of fault sound blades is more than 88%.

Genetic diversity analysis of recombinant inbred lines of bread wheat (Triticum aestivum L. Em. Thell) for stripe rust resistance using SSR markers

Paper ID- AMA-06-09-2021-10694

Molecular analysis revealed that out of 70 SSR primer pairs (including 40 Yr specific primers) used, 18 SSRs gave amplification. Seven Yr specific markers (Xgwm130 (Yr7), Xbarc 352 (Yr18), Xgwm 11 (Yr26), Xwmc 44 (Yr29), Xwmc 149 (Yr53), WKS1_I (Yr36) and Xcfb309 (Yr47) were polymorphic on RILs population. The amplified products varied from 120 bp to 350 bp. Cluster analysis at molecular level revealed that cluster I was the largest consisting of 39 RILs. This was followed by cluster X (33 RILs), cluster V (2 8 RILs), cluster VII (19 RILs), cluster IX (19 RILs), cluster VI (18 RILs) and cluster XI (18 RILs), cluster XII (15 RILs), cluster VIII (11 RILs), cluster III (7 RILs) and cluster XIII (5RILs). The scattered diagram on the molecular marker diversity analysis revealed that the fourteen RILs (50, 52, 56, 58, 59, 72, 97, 98, 118, 119, 120, 159, 184 and 193) were diverse. The grouping of recombinant inbred lines was not similar as in case of grouping based on morphological traits. Molecular Clustering as well as NTSYS-PC analysis clearly indicated that the recombinant inbred lines were scattered between the two parental wheat genotypes, WH711 and WH542, with an inclination towards WH542 (yellow rust resistant parent).

Determination of Optimum Farm Power and Machinery Requirement for Large Scale Sugarcane Production.

Paper ID- AMA-05-09-2021-10693

There was need to optimally determine farm power and machinery critically not only because of the high proportion of total cost attached to machinery but also of the infrequency and irrevocability of such decisions to reduce operational loss. Values of tractors with its equivalent implements field capacity, draft and power requirements, field operations ownership and operational cost for 1,300 ha Sunti sugarcane cultivation operations for 2017 and 2018 cropping seasons were determined based on farm size, weather, soil conditions and time available with regard to crop operation cultivation sequence. The available tractors and equivalent implements at site were found to be more than the number actually required except for the cane loaders, cane transporting wagons and all the cane harvesters were not in good condition, hence cane was 100% manually harvested for these cropping seasons. There was enough earth work equipment available for land clearing/development, road construction/maintenance, dyke, irrigation and drainage works. Result of field cropping operation sequencing calendar shows that operations were overlapping with multi-periods and peak periods in November to February. With reference to economic aspects of tractor utilization in this study, average use per tractor was lower than accepted range for large sized farm at peak months of operation period of November, January and February during tillage, sowing and harvesting. Actual number of tractors/implements used was more than optimum requirement, hence the farm has low number of total tractor use which made the system to have more tractors in proportion to the amount of work done.

Formation of Camelina sativa yield depending on the level of mineral fertilization under conditions of Precarpathians

Paper ID- AMA-05-09-2021-10692

The influence of growing technology elements of Camelina sativa, in particular, influence of different fertilizer doses on yielding capacity of Camelina sativa plants under conditions of Precarpathians of Ukraine has been studied. Main results of three-year research concerning improvement of existing technologies of growing Camelina sativa variety Girsky depending on the background of mineral nutrition and application of micro-fertilizers and growth stimulants which would maximize varietal characteristics of the crop and meet the needs of farmers have been presented. It was found that the highest yield of Camelina sativa 1.95 t/ha had been obtained with application of mineral fertilizers in a dose of N30P45K45+N60, which was 0.99 t/ha more than in the control. The lowest yield - 0.96 t/ha was obtained in the control variant (without fertilizers).

Mathematical Model for Calculating Humus Balance and Doses of Organic Fertilizers Using Big Data

Paper ID- AMA-05-09-2021-10690

The article presents mathematical models to forecast the humus balance of agricultural lands in the Central region of Russia, developed by scientists of Federal State Budgetary Scientific Institution FSAC VIM on the basis of an array of big data of field experiments of the Geographic Network of Federal State Budgetary Scientific Institution "All- Russian Research Institute of Agrochemistry". On the basis of the presented mathematical models, a software package has been formed, the use of which makes it possible to predict the dynamics of humus in the system of crop rotations, doses and total demand for organic fertilizers necessary to maintain a positive balance of soil organic matter with a known specific weight of perennial grasses, to produce a rational formation of the structure of sown areas, crop rotations and agricultural technologies aimed at preserving and increasing soil fertility and its biological activity.
