Attenuation Characteristics and Seismicity Analysis of Himalayan Region with Linear Joint Time-frequency Analysis Techniques
About 59% of the land area of the Indian subcontinent has high chances of moderate to severe earthquakes, of which the Himalayas are the most seismically active. Regardless of the high seismic activity, the seismic network ... -
Evaluating Climate Change Mitigation & Adaptation Potential of Sustainable Urban Transport Measures in India
The global climate is transforming due to increased GHG emissions. Globally, the response to climate change has been through mitigation to reduce greenhouse gas emissions. Urban transportation is the second leading source ... -
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract Fatigue phenomenon is a gradual, permanent, micro structural change that takes place in a material due to the application of repeated loading. In the case of quasi-brittle materials like graphite and concrete, ... -
Extra-cellular Polysaccharides and Microbially Induced Carbonate Cementation Using Indigenous Microbes in Cattle Manure
Soft soils are composed of large portions of silts and clay and are characterized by low strength and high compressibility owing to their high-water content. Biocementation techniques are emerging as a strong alternative ... -
Hammer Energy Ratios of Different Spt Setups Using Indigenous Hammer Energy Measurement Apparatus
Standard Penetration Test (SPT) is carried using different components and lifting mechanisms, which causes variation in energy efficiency and the inverse relationship between energy transferred to drill rod and N value was ... -
Hyperspectral Remote Sensing for Land Cover Classification and Chlorophyll Content Estimation using Advanced Machine Learning Techniques
In the recent years, remote sensing data or images have great potential for continuous spatial and temporal monitoring of Earth surface features. In case of optical remote sensing, hyperspectral (HS) data contains abundant ... -
Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ... -
Novel Numerical Procedures for Limit Analysis: Implementation to Planar, Axisymmetric and Three-Dimensional Geomechanics Stability Problems
The Current research in the field of computational limit analysis dwells upon the development of numerical tools which are sufficiently efficient and robust to be used in engineering practices. This places demands on the ... -
Spatial downscaling and analysis of satellite and ground-based rainfall for hydrological modelling
Precipitation is a vital element of the global hydrological and energy cycles, which is intermittent and highly variable in both space and time. Accurate measurements of precipitation at various space and time scales are ... -
Studies on alkali activated compressed earth bricks for structural masonry
Earth based construction materials are acknowledged as low carbon and low embodied energy materials. The investigations dealt in the thesis were mainly focused on exploring the geopolymer and lime-ground slag binders for ... -
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ... -
Weakly cemented granular materials: study at multiple length scales
Cemented granular systems are encountered at various scales in nature and artificially. We present an experimental study carried out on the structure and mechanical behaviour of weakly cemented granular materials. We study ...
