Machine Learning for Soil Fertility and Plant Nutrient Management Using Back Propagation Neural Networks

Abstract: The objective of this paper is to analysis of main soil properties such as organic matter, essential plant nutrients, micronutrient that affects the growth of crops and find out the suitable relationship percentage among those properties using Supervised Learning, Back Propagation Neural Network. Although these parameters can be measured directly, their measurement is difficult and expensive. Back Propagation Networks(BPN) are trained with reference crops’ growth properties available nutrient status and its ability to provide nutrients out of its own reserves and through external applications for crop production in both cases, BPN will find and suggest the correct correlation percentage among those properties. This machine learning system is divided into three steps, first sampling (Different soil with same number of properties with different parameters) second Back Propagation Algorithm and third Weight updating. The performance of the Back Propagation Neural network model will be evaluated using a test data set. Results will show that artificial neural network with certain number of neurons in hidden layer had better performance in predicting soil properties than multivariate regression. In conclusion, the result of this study showed that training is very important in increasing the model accuracy of one region and result in the form of a guide to recognizing soil properties relevant to plant growth and protection.

Virtual Laboratory for Performing Tests on a Single-Phase Power Transformer

Abstract: This paper presents a virtual laboratory for testing a single-phase power transformer using MATLAB Simulink environment. The models presented herein replicate the actual tests like no-load test, short-circuit test, load test, and short heat run test successfully well within tolerable accuracy. The rating of the transformer is taken to be 2 kVA, 230/115 V, 50 Hz which is a typical rating for transformers usually employed for practical classes in the Electrical Machine Laboratory for undergraduate courses. This model is attractive to students and they are able to gain insights into operational aspects of a single-phase power transformer. This model, in whole or part, may also be used as final year projects of engineering undergraduate students.

Effect of fluid concentration using a multi-nozzle on grinding performance

Abstract: Grinding fluid, apart from controlling temperature produced at the wheel-work contact zone by way of cooling also helps in lubrication which is achieved by reduction of friction at the wheel-workpiece interface. In the present experimental investigation, grinding fluid is delivered into the grinding zone by a multi-nozzle system in order to determine grindability of low alloy steel at different fluid concentrations. A comparative study has been made among dry and wet grinding using three different coolant concentrations, considering various response parameters, to assess grinding performance at a particular in feed. It is found that high concentration of oil in the fluid produced good results in terms of force requirement and surface roughness.

Study of the Effect of Tangential Point Blowing on the Incompressible Boundary Layer Flow Around a Circular Cylinder

Abstract: In the present work, two dimensional flow simulations have been performed to study the effect of tangential blowing on the drag force for the case of flow around a circular cylinder only at Reynolds number (Re) 200 Blowing ports have been placed symmetrically with respect to the horizontal flow axis The effect of blowing on the boundary layer has been studied with respect to the intensity of blowing as well as port position of blowing For a particular intensity of blowing, oscillations of the front stagnation point and the separation point was studied It was found that oscillation frequencies were identical with that of lift coefficient It was also observed that with the increase of the intensity of the blowing the position of the separation point shifts downstream (separation delay)thus the wake becomes narrower resulting the decrease of drag Strouhal number was found to increase with the intensity of blowing It was observed that the Strouhal number as well as the position of the separation point is influenced by the position of the blowing port Although, for a significant range of the blowing port positions the Strouhal number is observed to be constant Drag was found to be influenced by the position of the blowing ports Pressure drag was found to be more significant Thus total drag is influenced primarily by the pressure drag It was observed that in the range of 40° to about 110° for the position of the blowing port drag decreased But beyond 110° it increased againCopyright © 2014 by ASME

Dual-frequency radiometric measurement of changes in rainfall intensity

Abstract: Rainfall intensity retrieval from satellite data and its comparison with the meteorological sensors suffer from a lack of data for an optimal time period. The ground-based dual-frequency microwave radiometers at Vale do Paraiba (23° S) and Alcantara (2° S), Brazil, were installed under a project, CHUVA, during 1 November to 1 December 2011 and 7 March to 7 April 2010, respectively. The results show that a 1½ h interval would be the optimal time period, providing a better accuracy than 30 min, 1 h, and 2 h intervals. The differential method was established for suitably measuring rainfall intensity using the ground-based radiometric method. The results show that the coefficient of determination () values for Vale do Paraiba and Alcantara are 0.86729 and 0.90124; correlation coefficient (r) values are 0.9312 and 0.9493; reduced chi-square (χ2) values are 2.00815 and 21.4865, and the root mean square error (RMSE) values are 0.749 and 0.900, respectively. The differential method in finding the rainfall intensi...
