The purpose of this paper is to present the design, the math model, the result simulation, and discussion of a back-propagation neural network (BB-NN) for a two-mass system. The aim is to controller design simply and control the actual angular speed matching with the reference angular speed, lead to reduces the resonance oscillation at shaft between motor and load. BP-NN controller is designed based on the backward propagation of errors and training artificial neural networks are used in combination with an optimized method as gradient descent. This method calculates the gradient of the loss function with all the relevant weighting in the neural network. This gradient is fed into the optimization method, which uses it to update the weights, to minimize the loss function. The efficiency of the BB-NN control method is verified by HIL real-time simulation.
Energy is currently one of the most fundamental resources that countries need for economic and social development. Energy needs are increasing day by day as a result of increasing population, global growth and industrialization. However, fossil fuels used to meet this increasing energy demand are gradually decreasing. Therefore, it is necessary for countries to benefit from clean, cheap and easily available energy resources in order to compete economically. For this reason, Renewable Energy (RE) sources are widely used today as an alternative to traditional energy sources. Consequently, multi-criteria decision-making methods have been used in this study to evaluate criteria, such as the availability of renewable energy resources in Turkey, initial installation costs, continuity and efficiency, together. The multi-criteria decision making methods used in this study were WASPAS, Fuzzy TOPSIS and MULTIMOORA, which have frequently featured in published literature over recent years. It is aimed to give Turkey to a more sustainable future in this area by focusing on the evaluation of renewable energy sources. The study is intended to be a valuable resource for renewable energy scientists and for future studies.
In this paper, the investigation is strived to examine the growth trend of major pulses in India. The study is conducted on Bengal gram, Black gram, Pegionpea, Chickpea and Green gram for the 1990- 2020 periods. The total duration of 30 years is divided into three decades to know the in-depth decadal growth of the area, production, and productivity. For the above period, the average compound growth rate (CGR) in major states for Bengalgram as 2.82, 1.34, and 3.5, for Black gram -0.69, 0.53, and 0.215, for Pegionpea 0.65, 1.29, and 0.61, for Chickpea 1.27, 0.96, and 0.74, and for Green gram -0.71, 0.55, and 0.116 is observed in the area, production, and productivity. Decadal growth also approximately reflected similar trend for all the major pulses. Low productivity and low net return are minimizing the profit in this highly remunerative crop.
Pink anemonefish (Amphiprion perideraion) has commercial value as a popular aquarium fish and due to its collection from the wild there are concerns for the conservation of the species. Six polymorphic microsatellites were used to reveal population genetic structure of pink anemonefish from three locations (Quang Nam, Khanh Hoa – Ninh Thuan and Phu Quoc) in Vietnam. Analyses showed evidence for high levels of gene flow among populations sampled from the South China Sea (FST = 0.008, P > 0.05). Genetic homogeneity of A. perideraion in this region is likely due to the oceanographic-driven interaction of pelagic larvae in central waters off Vietnam. In contrast, strong genetic structure was evident among the South China Sea and Gulf of Thailand populations (FST = 0.131 – 0.146, P < 0.01). This high genetic differentiation between the South China Sea and Gulf of Thailand populations suggests that the sustainable management of this species in Vietnam needs to be enacted according to indigenous need as a two separate stocks.
A field experiment was conducted for two years (rabi 2016 and rabi 2017) at SKUAST-Jammu to study the effect of differential substitution nutrients through organics on yield, nutrient uptake and profitability of knol khol (Brassica oleracea var gonylodes L.) in subtropical region of J&K. Experiment was conducted in randomized block design with sixteen treatments. The results of the study revealed that significant effect of differential substitution nutrients through organics were observed on growth parameters viz., plant height, number of leaves plant and dry matter accumulation (g/plant); yield and nutrient uptake at harvest in knol khol during both the years. Significantly highest plant height (33.14cm and 36.44cm), number of leaves/plant (15 and16.20), dry matter accumulation (28.38 g/plant and 32.65g/plant), knol khol yield (712.35q/ha and 734.79q/ha), net returns (Rs 309281 /ha and Rs 211905 /ha) were recorded with recommended dose of fertilizer during both the years where as lowest value of all these parameters were recorded with 100 % N through FYM. Significant difference between treatments was also recorded for nitrogen uptake and potassium uptake during both the years.
