Ecology of the terrestrial carbon cycle: Influence of climate and animals
The terrestrial carbon (C) cycle involves fluxes between multiple pools that determine ecosystem functions and regulate global climate. These fluxes and pools are influenced by changes in abiotic (temperature, precipitation ... -
Characterization and Control of Boundary Layer Transition Caused by Distributed Surface Roughness
Distributed roughness occurs over a variety of aerodynamic surfaces such as wind-/gas-turbine blades and aircraft wings in the form of dust, insect strikes, fouling or icing. The disturbances introduced by the roughness ... -
High-Throughput Bending Tests for Investigating Creep Behavior Affected by Structural and Microstructural Inhomogeneities
The bending of cantilevers is an alternate technique for the extraction of power-law creep parameters of materials. It has been shown earlier that in homogeneous systems showing tension-compression symmetry, digital image ... -
Damping of magnetic-Coriolis waves with imposed magnetic field orthogonal to the axis of rotation
Small-scale columnar structures (<10 km radius) in Earth's outer core result from inertial waves. In highly conducting fluid, magnetic field behaviour resembles stretched elastic strings and transmits disturbances as Alfvén ... -
Ground Displacements and Stresses around Single and Twin Tunnels using Analytical and Numerical Approaches
Significant emphasis is given nowadays on exploring underground space- in the form of tunnels- for (i) fast commuting in urban areas, (ii) connectivity to remote areas under different weather conditions, (iii) military ... -
Bioinspiration for battling bacteria: Nature inspired high aspect ratio nanostructures for new age antibacterial surfaces
Bacterial colonization and biofilm formation on abiotic surfaces effectuate corrosion, fermentation, and infection resulting in tremendous economic and human losses each year. Aggravating the situation, new multi-drug ... -
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ... -
An Energetics Perspective for the Response of the Indian Summer Monsoon to Land Processes in a Coupled General Circulation Model
The Indian summer monsoon is a coupled land-ocean-atmosphere phenomenon that supplies about 80% of the annual rainfall that the region receives. The monsoon season typically begins on June 1 st with a steep rise in rainfall ... -
Microstructure-Corrosion Property Correlation in Electrodeposited Sn and Cu Based Coating Systems
Conventional metallic coatings are widely used for protection against corrosion. This study investigates the correlation between microstructure and corrosion properties in SnCr and CuCr electrodeposited coatings. The wide ... -
Investigations on the Use of Mems-imu Sensors for Manual 2D and 3D Ultrasound Imaging
Ultrasound imaging is a safe medical imaging technique with many applications in medical diagnostics. MEMS-IMUs being small-size, low-cost, low-power devices suitable for accurate orientation estimation, the chances of ... -
Investigating Ocular and EEG parameters for pilot’s cognitive load estimation using flight simulators
Present day aircraft systems are becoming incredibly complicated with the advent of new technologies. As per International civil aviation organization’s safety report, failure of mechanical or any physical hardware has ... -
Investigations into the Thermo-chemical Conversion of Simulated Refuse Derived Fuels with Different Plastic Contents
The burgeoning problem of municipal waste generation along with its disposal problem has urged the development of sustainable waste management practices such as waste-to-energy conversion. Refuse-derived fuel (RDF) represents ... -
Seismic evaluation of 3D tunnels in near fault ground motion using domain reduction method
Underground tunnels are an essential part of transportation and utility networks, and their vulnerability to earthquakes has significant socio-economic impacts. Tunnels have suffered substantial damage in past earthquakes, ... -
Impact of 3D distribution of Black Carbon aerosols in the atmosphere on aerosol radiative forcing over the Indian region
Black Carbon (BC) aerosols are produced by the incomplete combustion of carbonaceous materials. While they constitute an insignificant mass-fraction of the composite atmospheric aerosols, their measurement is essential in ... -
Studies on Two-Stage Air-Cooled Silica gel + Water Adsorption Cooling System
Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ... -
