Methane Storage In Activated Carbon Nanostructures : A Combined Density Functional And Monte Carlo Study
(2011-08-04)Natural gas is stored as compressed natural gas (CNG) in heavy steel cylinders under pressures of 200-250 atm. However, such a method of storage has certain disadvantages which include multistage compression costs, limited ... -
Methanol Synthesis from Simulated Bio-syngas: Experimental and Modeling Studies
Methanol is increasingly being considered as an alternative fuel due to its potential to reduce environmental pollution and its ability to be used directly in internal combustion engines without any engine modification. ... -
A Method to Derive an Aerosol Composition from Downward Solar Spectral Fluxes at the Surface
(2018-01-01)Aerosol properties are highly variable in space and time which makes the aerosol study more complex. The sources and production mechanism of aerosols decide the properties of the aerosols. Aerosol radiative forcing is ... -
Methodologies for Assessment of Impact Dynamic Responses
(2017-11-24)Evaluation of the performance of a product and its components under impact loading is one of the key considerations in design. In order to assess resistance to damage or ability to absorb energy through plastic deformation ... -
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ... -
A Methodology To Recover Unstable Aircraft From Post Stall Regimes: Design And Analysis
(Indian Institute of Science, 2006-07-26)This thesis deals with high angle of attack behaviour of a generic delta wing model aircraft. A high angle of attack wind tunnel database has been generated for this aircraft and based upon the bifurcation analysis of the ... -
Methods For Forward And Inverse Problems In Nonlinear And Stochastic Structural Dynamics
(2009-09-03)A main thrust of this thesis is to develop and explore linearization-based numeric-analytic integration techniques in the context of stochastically driven nonlinear oscillators of relevance in structural dynamics. ... -
Methods on Probabilistic Structural Vibration using Stochastic Finite Element Framework
(2018-02-07)Analysis of vibration of systems with uncertainty in material properties under the influence of a random forcing function is an active area of research. Especially the characterization based on mode shapes and frequencies ... -
MHD Waves Driven by Small-scale Motion and Implications for the Earth's Core
(2018-05-22)Rotating convection in the Earth's core produces columnar vortices of radius ~10 km or less near the inner core boundary. Small-scale motions in the core can travel as Alfvén waves in the face of Ohmic diffusion, provided ... -
Micro-Blast Waves
(2014-09-02)The near field blast–wave propagation dynamics has been a subject of intense research in recent past. Since experiments on a large scale are difficult to carry out, focus has been directed towards recreating these blast ... -
Micro-Mechanisms Associated with Friction Stir Welding of Aluminum with Titanium
(2018-01-10)Out of the known aerospace metal and alloys, Aluminium (Al) and Titanium (Ti) are important due to their unique combination of properties, such as strength, ductility and corrosion resistance etc. For these reasons, welding ... -
Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ... -
Micro-scale Fracture Testing of Graded (Pt,Ni)Al Bond Coats
(2018-04-16)PtNiAl bond coats are diffusion aluminide coatings deposited on superalloy based turbine blades for oxidation resistance and improved adhesion between the substrate and the YSZ thermal barrier coating on top. They are ... -
Microbially-induced Mineral Flocculation and Flotation with Proteins and Polysaccharides Isolated from Paenibacillus
The most significant environmental issue that has arisen in the mining industries over the last decade is that of acid mine drainage (AMD) from tailing dumps and waste mined rock piles. AMD is caused by the oxidation of ... -
Microgravity Flow Transients in the Context of On-Board Propellant Gauging
(2018-02-15)It is well known that surface tension of a liquid has a decisive role in flow dynamics and the eventual equilibrium state, especially in confined flows under low gravity conditions and also in free surface flows. One such ... -
Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry demands a thorough understanding of its failure process under different types of loading. The composite nature of cementitious ... -
Micromechanical understanding of the macroscopic features of dense granular materials
The prevalence of granular materials in nature (soil, beach sand, rubble pile asteroids) and in several industries (cement, food grains, pharmaceutical powders) has motivated extensive research towards understanding the ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
