Establishment of an Experimental System in India to Measure the Mixing Ratio and Stable Isotopic Composition of Air CO2 & Observations from Urban and Marine Environments
(2018-04-11)
The thesis presents observations on the CO2 mixing ratio and the carbon isotopic ratio (13C/12C i.e. δ13) of atmospheric CO2 from the Indian region, for the period 2008 - 2011. An experimental system was established at the ...
Assessment of Leachate Characteristics and Geotechnical Properties of Municipal Solid Waste Landfill
(2018-01-04)
Solid Waste Management is one of the essential services provided by local bodies to keep the urban areas clean. Often it is poorly rendered as it is unscientific, out-dated and inefficient. With the rapid increase in ...
Studies on The Transport Rates of Heavy Metals in the Design of Liner Thickness and Remediation of Soils
(2018-01-01)
The enormous rate of increase in waste generation across the world is a serious threat to the future generation, if not handled properly, due to the creation of health hazards and global warming. This was awakened many ...
Modeling and Analysis of Water Distribution Systems
(2018-01-09)
In most of the urban cities of developing countries piped water supply is intermittent and they receive water on alternate days for about few hours. The Unaccounted For Water (UFW) in these cities is very high due to aged ...
Analytical and Numerical Modeling for Heat Transport in a Geothermal Reservoir due to Cold Water Injection
(2018-01-09)
Geothermal energy is the energy naturally present inside the earth crust. When a large
volume of hot water and steam is trapped in subsurface porous and permeable rock
structure and a convective circulating current is set ...
Computational Studies on the Mechanics of Nanotubes and Nanocomposites
(2018-01-09)
The discovery of carbon nanotubes (CNTs) in 1991 by Iijima revealed the possibility of ultra-strong materials exploiting the properties of materials at smaller length scales. The superior strength, stiffness, and ability ...
Mechanics of Drilling in Porous Brittle Solids
(2018-01-01)
This thesis presents a detailed experimental programme on understanding the mechanics of drilling in porous brittle solids. Gypsum was used as a model material for this experimental study, in which the mechanics of drilling ...
Formation of Porous Metallic Nanostructures Electrocatalytic Studies on Self-Assembled Au@Pt Nanoparticulate Films, and SERS Activity of Inkjet Printed Silver Substrates
(2018-04-24)
Porous, conductive metallic nanostructures are required in several fields, such as energy conversion, low-cost sensors etc. This thesis reports on the development of an electrocatalytically active and conductive membrane ...
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)
Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ...
Estimation of Daily Actual Evapotranspiration using Microwave and Optical Vegetation Indices for Clear and Cloudy Sky Conditions
(2018-05-25)
Evapotranspiration (ET) is a significant hydrological process. It can be studied and estimated using remote sensing based methods at multiple spatial and temporal scales. Most commonly and widely used remote sensing based ...
