Abstract Mines result in land use and cover (LULC) change due to degradation of natural resources establishment new infrastructure for ore extraction beneficiation. The present study was carried out to, with objectives, (1) characterize LULC (from 1975 2017) Khetri copper mine region, (2) spatial distribution pollution indices (3) spectral response elemental concentration soil groundwater using...

Hyperspectral image (HSI) classification is an important concern in remote sensing, but it complex since few numbers of labelled training samples and the high-dimensional space with many spectral bands. Hence, essential to develop a more efficient neural network architecture improve performance HSI task. Deep learning models are contemporary techniques for pixel-based hyperspectral classificati...

ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...

Anxiety, learning disabilities, and depression are the symptoms of attention deficit hyperactivity disorder (ADHD), an isogenous pattern hyperactivity, impulsivity, inattention. For early diagnosis ADHD, electroencephalogram (EEG) signals widely used. However, direct analysis EEG is highly challenging as it time-consuming, nonlinear, nonstationary in nature. Thus, this paper, a novel approach (...

The dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. With the help of displacements and stresses Green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...

Background: The standard patch test is known as the most reliable test to identify and confirm causative agents of allergic contact dermatitis (ACD). Previous studies have shown that the prevalence of specific allergens varies by geographic area. The results of patch test in patients visiting our dermatology clinics with suspected ACD were prospectively investigated and compared with those repo...

Computational fluid dynamics is implemented to investigate the influence of the wheel contact patch on the global car aerodynamics. Two main aspects of the problem are the contact step and patch shape. Three important parameters: step height, cut angle, and tire tread shape are taken into consideration. For validations of the numerical results, the experimental data are also considered. The obt...

In this work, we propose a new method to inpaint the CMB signal in regions masked out following point source extraction process. We adopt modified Generative Adversarial Network (GAN) and compare different combinations of internal (hyper-)parameters training strategies. study performance using suitable $\mathcal{C}_r$ variable order estimate regarding power spectrum recovery. consider test set ...
