Kalman Filter Estimation Of Ionospheric TEC And Differential Instrumental Biases Over Low Latitude Using Dual Frequency GPS Observations
(2009-03-13)
The low latitude tropical ionosphere has been investigated by various researchers
using Global Positioning System (GPS). Presently for many civil aviation applications, the ionospheric modeling of the tropical region has ...
Kinetic Flux Vector Splitting Method On Moving Grids (KFMG) For Unsteady Aerodynamics And Aeroelasticity
(Indian Institute of Science, 2007-06-07)
Analysis of unsteady flows is a very challenging topic of research. A decade ago, potential flow equations were used to predict unsteady pressures on oscillating bodies. Recognising the fact that nonlinear aerodynamics is ...
Ultra High Compression For Weather Radar Reflectivity Data
(2007-10-09)
Weather is a major contributing factor in aviation accidents, incidents and delays. Doppler weather radar has emerged as a potent tool to observe weather. Aircraft carry onboard radars but their range and angular resolution ...
Investigation of Heat Transfer Rates Around the Aerodynamic Cavities on a Flat Plate at Hypersonic Mach Numbers
(2018-07-28)
Aerodynamic cavities are common features on hypersonic vehicles which are caused in both large and small scale features like surface defects, pitting, gap in joints etc. In the hypersonic regime, the presence of such ...
Wave Propagation in Sandwich Beam Structures with Novel Modeling Schemes
(2017-10-31)
Sandwich constructions are the most commonly used structures in aircraft and navy industries, traditionally. These structures are made up of the face sheets and the core, where the face sheets will be taking the load and ...
Wave Propagation in Healthy and Defective Composite Structures under Deterministic and Non-Deterministic Framework
(2018-03-08)
Composite structures provide opportunities for weight reduction, material tailoring and integrating control surfaces with embedded transducers, which are not possible in conventional metallic structures. As a result there ...
Nature Inspired Optimization Techniques For Flood Assesment And Land Cover Mapping Using Satellite Images
(2017-04-21)
With the advancement of technology and the development of more sophisticated remote sensing sensor systems, the use of satellite imagery has opened up various fields of exploration and application. There has been an increased ...
Optimal Trajectory Planning for Fixed-Wing Miniature Air Vehicles
(2018-04-02)
Applications such as urban surveillance, search and rescue, agricultural applications, military applications, etc., require miniature air vehicles (MAVs) to fly for a long time. But they have restricted flight duration due ...
Robust Adaptive Control of a Laser Beam System for Static and Moving Targets
(2018-02-28)
The motivation of this thesis is to propose a robust control technique for a laser beam system with target estimation. The laser beam is meant to track and fall on a particular portion of the target until the operation is ...
Analysis of Rotating Beam Problems using Meshless Methods and Finite Element Methods
(2018-03-01)
A partial differential equation in space and time represents the physics of rotating beams. Mostly, the numerical solution of such an equation is an available option as analytical solutions are not feasible even for a ...
