Scour is the main cause of failure for spur dike. The accurate prediction scour around dike essential to design a present study focuses on maximum depth in equilibrium condition and parameters, which influence it sand–gravel mixture bed. Outcomes experimental showed that non-dimensional increases with critical velocity ratio (U/Uca), water depth-armour particle (h/da), Froude number sediment (Frsm), depth-spur length (h/l), decreases increase armour particle-spur (da/l). proportional...
Abstract The quality of soil plays a crucial role in sustainable agriculture. To better understand the changes across different agroecosystems, long‐term experiments are considered as most effective approach. Moreover spite their significance, there is paucity information pertaining to impact fertilizer and manure application on Vertisols Central India. Thus, present study aimed assess an ongoing 46‐year experiment conducted central India, where soybean‐wheat cropping system (SWCY) was...
The experimental results of time average velocity components measured around circular pier models during transient scour stage using acoustic Doppler velocimeter are shown for flow pattern and turbulence characteristics. Totally, four experiments were performed under clear water conditions in a model gravel bed stream. Four diameter 6.6, 8.4, 11.5, 13.5 cm used this study. Detailed controlled measurements on components, intensities near the hole at 0° 180° plane shown. Flow structure...
Abstract. The delta of the Brahmani-Baitarani river basin, located in eastern part India, frequently experiences severe floods. For flood risk analysis and water system design, insights possible future changes extreme rainfall events caused by climate change are major importance. There is a wide range statistical dynamical downscaling bias-correction methods available to generate local projections that also consider extremes. Yet applicability these highly depends on availability...
A two-layered suspension flow, consisting of a central layer particle-fluid and peripheral Newtonian viscous fluid (same as the suspending medium in layer), induced by sinusoidal peristaltic waves has been studies. The expressions for velocity profiles, pressure drop friction force have obtained. shown to be increasing with particle concentration core region also flow rate. magnitude is found higher one-layered (one-fluid) analysis than (two-fluid) given value It noticed that small values...
Maitri Station (70.76°S; 11.73°E) is located in Schirmacher Oasis, a coastal nunatak north-central Dronning Maud Land covering an area of 35 km2. Here, we report results from the first magnetotelluric experiments and delineate deep electrical conductivity structure under Oasis using data acquired during 24th Indian Antarctic Scientific Expedition. The method has advantage shallow to deeper level coverage as acquisition covers wide frequency band 10-3103 Hz, permitting different penetration...
This paper presents experimental results of turbulence characteristics flow using Acoustic Doppler Velocimeter over the degraded channel bed made clay–silt–sand mixture in which clay varied as 0, 30, and 50%. The vertical distribution velocity, intensity, kinetic energy, Reynolds shear stress has been at different sections bed. resultant velocity was found to be reversal near surface especially upstream working section. Normalized intensity maximum around initial level corresponding 30 50%...
The in-band full-duplex (IBFD) mechanism offers many advantages over standard half duplex (HD) systems: it can potentially double the capacity and increase spectrum utilization efficiency. While IBFD renders conventional research problems irrelevant, unearths several new that urgently need attention. We focus on a design of Licensed Shared Access (LSA) based sharing framework with multi-cell multi-user multiple-input multiple-output (MIMO) communication network as licensee, which operates in...
Land use/land cover, along with climate variability, play vital roles in hydrological functionality of catchments and are leading threats to inter-related processes. In the current study, a physically distributed Soil Water Assessment Tool model is used investigate impact historical changes on hydrologic response Damodar catchment (Jharkhand, India) terms inflow Panchet reservoir. The was validated for monthly runoff at outlets four watersheds three reservoirs before assessment reservoir...
A stability-indicating high-performance liquid chromatographic (HPLC) method was developed with short run time and validated for the assay of process related impurities pantoprazole in bulk form. Resolution drug, its potential degradation products were achieved on a Hypersil ODS column utilizing gradient 0.01 M phosphate buffer pH 7 acetonitrile as eluent, at detection wavelength 290 nm. Flow rate set 1 mL min-1. The procedure found to be specific, linear (r=0.999), recovery (97.9-103%), LOD...
The flow field within a transonic axial compressor stage has been computed using three-dimensional time-marching technique. Limited viscous effects are considered by including calculation of the blade surface boundary layers. layer forms an integral part whole computation scheme, which consists of, respectively: (i) inviscid Mach number calculations, (ii) displacement thickness (iii) calculations with mass adjustment (based on calculated thicknesses) surfaces. is done methods and...
Abstract Severe floods are common in the Brahmani-Baitarani river basin India. Insights into implications of climate change on rainfall extremes and resulting major importance to improve flood risk analysis water system design. A wide range statistical dynamical downscaling bias-correction methods for generation local projections exists. Yet, applicability these highly depends availability meteorological data. In developing countries, data is often limited, either because do not exist or...
An in-band full-duplex (IBFD) multiple-input multiple-output (MIMO) radio's self-interference (SI) and co-channel interference (CCI) cancellation strengths usually determine its performance gains over conventional half-duplex ones. Accordingly, this paper explores an alternative to traditional optimization driven design (ODD) techniques available in the literature for beamformer IBFD radios. In particular, mitigate residual SI CCI, we propose a run-time data-driven prediction approach...
