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 ...
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 ...
Experimental Investigations Of Surface Interactions Of Shock Heated Gases On High Temperature Materials Using High Enthalpy Shock Tubes
(2009-05-12)
The re-entry space vehicles encounter high temperatures when they enter the earth atmosphere and the high temperature air in the shock layer around the body undergoes partial dissociation. Also, the gas molecules injected ...
Analysis Of Coupled-Resonator Slow-Wave Structures For Traveling-Wave Tubes For Aerospace Applications
(2009-04-30)
Through continued innovation and growth, traveling wave tube amplifiers (TWTAs) remains the microwave power amplifiers of choice in a wide range of high power microwave and millimeter-wave applications specifically for ...
Piezoceramic Dynamic Hysteresis Effects On Helicopter Vibration Control Using Multiple Trailing-Edge Flaps
(2009-07-14)
Helicopters suffer from severe vibration levels compared to fixed-wing aircraft. The main source of vibration in a helicopter is the main rotor which operates in a highly unsteady aerodynamic environment. Active vibration ...
Weighted Least Squares Kinetic Upwind Method Using Eigendirections (WLSKUM-ED)
(2009-06-24)
Least Squares Kinetic Upwind Method (LSKUM), a grid free method based on kinetic
schemes has been gaining popularity over the conventional CFD methods for computation
of inviscid and viscous compressible flows past complex ...
