Structural Health Monitoring Of Composite Structures Using Magnetostrictive Sensors And Actuators
(2009-07-14)
Fiber reinforced composite materials are widely used in aerospace, mechanical, civil and other industries because of their high strength-to-weight and stiffness-to-weight ratios. However, composite structures are highly ...
An Autonomous Guidance Scheme For Orbital Rendezvous
(Indian Institute of Science, 2005-07-15)
The word 'rendezvous' implies a pre-arranged meeting between two entities for a specific purpose. This term is used in the study of spacecraft operations, to describe a set of maneuvers performed by two spacecraft in order ...
Optimal Resource Allocation In Lanchester Attrition Model Based Conflicts
(2009-05-06)
Force deployment and optimal resource allocation has been an area of considerable research interest in conventional warfare. In the modern scenario, with significant advances in technology related to communication and ...
Glowworm Swarm Optimization : A Multimodal Function Optimization Paradigm With Applications To Multiple Signal Source Localization Tasks
(2009-05-05)
Multimodal function optimization generally focuses on algorithms to find either a local optimum or the global optimum while avoiding local optima. However, there is another class of optimization problems which have the ...
Genetic Programming Based Multicategory Pattern Classification
(Indian Institute of Science, 2005-02-22)
Nature has created complex biological structures that exhibit intelligent behaviour through an evolutionary process. Thus, intelligence and evolution are intimately connected. This has inspired evolutionary computation ...
An Investigation of Architectures For Integration Of Stand-Alone INS And GPS Navigation Systems
(2009-07-08)
Inertial navigation systems (INSs) have the well-known advantages of being self-contained, weatherproof, jam-proof, and non-self-revealing while providing stable navigation information with little high-frequency noise. ...
Onboard Propellant Gauging For Spacecraft
(2009-08-04)
Estimation of the total mission life of a spacecraft is an important issue for the communication satellite industries. For accurate determination of the remaining mission life of the satellite it is essential to estimate ...
Spontaneous Crack Propagation In Functionally Graded Materials
(2009-10-28)
Functionally graded materials (FGMs) are composites that have continuously varying material properties, which eliminate undesirable stress concentrations that might otherwise occur in layered composites. The concept of ...
Mode-3 Asymptotic Analysis Around A Crack Embedded In A Ductile Functionally Graded Material
(2009-09-15)
Functionally graded materials (FGMs) are composites with continuous material property variations. The distinct interfaces between the reinforcement and the matrix in classical composites are potential damage initiation ...
A High-Resolution Procedure For Euler And Navier-Stokes Computations On Unstructured Grids
(Indian Institute of Science, 2006-07-20)
A finite-volume procedure, comprising a gradient-reconstruction technique and a multidimensional limiter, has been proposed for upwind algorithms on unstructured grids. The high-resolution strategy, with its inherent ...
