Research paper thumbnail of Effect of Sulphur and Boron on Growth Characterstics, Yield Components and Productivity Parameters of Mustard (Brassica juncea L.) under Rainfed Condition of Chitrakoot Region, Madhya Pradesh, India

The sandy loam texture of the experimental soil has a medium availability of boron and sulphur. The experiment used a factorial randomised block design with nine treatment combinations and three replications. The Pusa Mahak mustard variety was grown using the advised agronomic methods. Based on the findings of the experiment, it was possible to draw the conclusion that applying 35 kg S ha-1 + 2.5 kg B ha-1 40 DAS to mustard greatly boosts the plant's growth parameter i.e. plant height, no. of leaves and no. of branches and yield attributes i.e. number of pods per plant, number of seeds per pod and 1000 seed weight (gm The application of 35 kg S ha...

Research paper thumbnail of Comparative Study of Cyclic Hardening Behavior of SS 316 L Using Time Independent and Dependent Constitutive Modeling: A Simplified Semi-implicit Integration Approach

Transactions of the Indian Institute of Metals, 2015

A simplified expression for infinitesimal plastic strain increment is discussed. Investigation of cyclic hardening behavior of SS 316 L is carried out at various mean stresses under uniaxial cyclic mechanical loading. The corresponding results are aimed to differentiate the cyclic hardening/deformation behavior at room temperature and 550°C using time independent (Model-1) and time dependent (Model-2) constitutive models. Cyclic hardening phenomenon is characterized into Phases-I and-II representing rapid and slow hardening zones, respectively which further reveals the severity of damage during asymmetric cyclic loading for Models-1 and-2. Suitability of the constitutive models at different temperature and stressing rates is proposed depending on contribution of viscoplasticity/rate dependence. Present formulation is validated by comparing the results with previously published experimental data.

Research paper thumbnail of Improvement in physical and chemical properties of sodic soil by 3, 6 and 9 years old plantation of Eucalyptus tereticornis

The results showed an improvement in the physical as well as chemical properties of sodic soil. pH, electrical conductivity (EC) and exchangeable sodium percentage (ESP) values declined and the organic C, total N, available P and exchangeable Ca 2þ , Mg 2þ and K þ levels of the soils increased. There was a decrease in bulk density and an increase in soil porosity and water holding capacity of the soil. Saturation extract analysis revealed that the cations, other than Na þ increased while the anions alongwith pHs, ECe and sodium adsorption ration (SAR) decreased due to the influence of plantation on the soil. The ameliorative effect of the trees became more distinct with the increasing age of plantation. The study, therefore, brings out clearly that the productivity and fertility of the degraded sodic soils can be restored by tree plantation.

Research paper thumbnail of A naïve Gaussian Bayes classifier for detection of mental activity in gait signature

The proposed scheme is based on principal component analysis with reduced feature dimension followed by a naïve Gaussian Bayes classifier. The leave-one-out cross-validation shows the detection accuracy of 94% with specificity and sensitivity of 96% and 98.3%, respectively. The research has a potential application in the prevention of elderly risk falls, lie detection and rehabilitation among Parkinson's patients.
