Dynamically isotropic Gough-Stewart platform for micro-vibration isolation in spacecraft
Rotating components such as reaction wheels and momentum wheels on spacecraft generate micro-vibrations up to 250 Hz during on-orbit operations. While the use of Gough-Stewart Platforms (GSPs) for six degrees of freedom ... -
Analysis, Modelling, and Optimization of Gate-To-Gate Aircraft Operation for Enhanced Air Traffic Management
The global air passenger demand will surpass the 10 billion mark by the end of 2040. India itself is poised to become the third largest aviation market and traffic generator by 2033, with a forecast of over 950 million ... -
Emergence and Propagation of Aerodynamic Instabilities in Centrifugal Compressors with Vaned Diffusers: Effect of Solidity and Stagger
Centrifugal compressors are widely employed in turbochargers and small gas turbines due to their ability to achieve high compression per stage. These compressors consist of a rotating impeller and a static diffuser, which ... -
On structure preserving numerical schemes for hyperbolic partial differential equations and multiscale kinetic equations
Natural phenomena are frequently represented through the formulation of differential equations, coupled with specific initial and boundary conditions. Many such models possess inherent structures that are crucial in ... -
Developing Decision Support for Electric Vehicle (EV) Adoption & Charging Infrastructure Planning
Majorly reliant on petroleum products, the transportation sector accounts for 25% of the global energy demand and 23% of carbon dioxide emissions. Among all the modes of transportation, road vehicles are the primary sources ... -
Developing SCR Plate Catalysts for Sustainable NOx Reduction in High Dust Thermal Power Plants
The primary aim of this research is to address NOx emission reductions from high ash/dust environments of coal-driven thermal power plants prevalent in India and other regions using low-grade coal with significant fly ash ... -
Hexagonal boron nitride incorporated polymer nanocomposites for water remediation
The isolation of graphene in 2004 sparked a revolution in the study and applications of 2D nanomaterials in various disparate fields. Separation technology is no exception. 2D nanomaterials possess numerous desirable ... -
Modelling Multimodal Mode Choice Behaviour with Spatial Variability in Level of Service Attributes
Cities worldwide are grappling with declining public transit usage, primarily due to insufficient spatial coverage of mass transit corridors in sprawling urban regions and inadequate first- and last-mile connectivity options ... -
A Class of Vector Fields for Path Following Guidance
With rapidly evolving application scenarios, Unmanned Aerial Vehicles (UAVs) are often desired to autonomously follow predefined paths. Prospective path following guidance methods should cater to the dynamic capability of ... -
Investigating the role of moisture in vernacular and conventional building typologies for occupant comfort and health
Moisture is omnipresent and critical to sustain life on the planet. In buildings, it is observed in the form of indoor moisture, dampness on walls, seepages, etc. As building occupants, humans perceive moisture in the air ... -
Extraction of Bond Coat Mechanical Properties using High- Temperature Digital Image Correlation
Gas turbine engines used in aircraft or power generation widely use nickel-based superalloys in their hot sections such as combustion chambers, turbine blades, etc. These components in the hot section use thermal barrier ... -
A model-based investigation of the long-term climate and carbon cycle consequences of fossil fuel emissions, land use changes and negative emissions
In this thesis, we investigate the effects of anthropogenic perturbations such as fossil fuel emissions, deforestation, afforestation and negative emissions on the long-term climate and carbon cycle using simulations from ... -
Self-sustained oscillations in high-speed cylinder wake flows
Flow in the wake generated by a solid body presents an important class of problems in fluid dynamics, with wide ranging scientific implications and engineering applications. The present work investigates the structure and ... -
Multifunctional hydrogels with injectable, self-healing, and shape-morphing capabilities for biomedical applications
