Development of Optimal Distributed Resource Utilisation Approaches Under Connectivity Constraints for Energy Internet
The global transition to sustainable power generation has driven a rapid increase in Distributed Energy Resources (DERs), especially from renewable sources. When integrated with energy storage, these localised generation ... -
Development of Scalable UAV Swarm-based Cooperative Search and Mitigation Approaches for Wildfire Management
Climate change has significantly exacerbated wildfire seasons, increasing their frequency, duration, and scale of destruction. Globally, wildfires destroy approximately 400 million hectares of land annually, resulting in ... -
Development of Spatio-Temporal Multi-Task Assignment Approaches for Perimeter Defense Problem
Rapidly evolving technologies in the autonomous operation of Uninhabited Aerial Vehicles (UAVs) and associated developments in low-cost sensors have created significant interest among researchers in using them for various ... -
Differential Evolution Based Interceptor Guidance Law
(2013-05-29)Kinematics based guidance laws like the proportional navigation (PN) and many other linear optimal guidance laws perform well in near-collision course conditions. These have been studied thoroughly in the literature from ... -
Differential Games Guidance Laws for Aerospace Applications
(2018-07-26)This thesis addresses several aerospace guidance and decision making problems using both no cooperative and cooperative game theoretical solution concepts in the differential games framework. In the first part of the thesis, ... -
Direct Methods for Optimal Ascent Guidance
An ascent guidance algorithm determines the thrust vector that allows the spacecraft to reach the desired orbit. Generally, optimal ascent guidance algorithms try to reach the orbit while minimizing mission time or fuel. ... -
Discrete Velocity Boltzmann Schemes for Inviscid Compressible Flows
It is known that high-speed flows are compressible. In large parts of the flow domains, the inviscid approximation is valid and this leads to Euler equations of gas dynamics. These inviscid compressible flows are modelled ... -
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ... -
Distributed Computation With Communication Delays: Design And Analysis Of Load Distribution Strategies
(Indian Institute of Science, 2005-11-09)Load distribution problems in distributed computing networks have attracted much attention in the literature. A major objective in these studies is to distribute the processing load so as to minimize the time of processing ... -
Drilling Damage in Laminated Polymer Matrix Composites Considering Thermal Efefcts: Experimental and Numerical Analysis
In the present work, drilling induced damage in multi-directional carbon fiber reinforced polymer (MD-CFRP) laminates has been investigated by experimental and numerical approaches. Exit-ply delamination during drilling ... -
Dynamic behavior of electro-rheological fluid sandwich beams
Electrorheological (ER) fluids are fluids with controllable rheological properties. The study of change in rheology of suspensions due to application of electric field is of interest both from academic and industrial points ... -
Dynamic Response Of A Satellite With Flexible Appendages And Its Passive Control
(2010-11-25)Most present day spacecrafts have large interconnected solar panels. The dynamic behavior of the spacecraft in orbit can be modeled as a free rigid mass with flexible elements attached to it. The natural frequencies of ... -
Dynamics And Stability Of A Launch Vehicle
(2011-07-08)Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ... -
Dynamics of Actuated and Interacting Swirl Premixed Flames in Model Gas Turbine Combustors
Lean premixed combustion is preferred in gas turbines because of the reduced (NOx) emissions. However, the combustors operating in lean premixed regime could suffer from problems like flame flashback, flame blowoff and ... -
Dynamics Of Early Stages Of Transition In A Laminar Separation Bubble
(2010-04-12)This is an experimental and theoretical study of a laminar separation bubble and the associated transition dynamics in its early stages. The separation of a laminar boundary layer from a solid surface is prevalent in very ... -
Dynamics of Laminar Separation Bubbles on Low Reynolds Number Airfoils
This is a detailed study on the aerodynamics of low Reynolds number airfoils. E387 airfoil that comes under the category of trailing-edge stall is used extensively in this study. The reduction in lift due to low Reynolds ... -
