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 ... -
Wave Propagation In Hyperelastic Waveguides
(2014-06-20)The analysis of wave propagation in hyperelastic waveguides has significant applications in various branches of engineering like Non-Destructive Testing and Evaluation, impact analysis, material characterization and damage ... -
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 Transmission Characteristics in Honeycomb Sandwich Structures using the Spectral Finite Element Method
(2017-12-12)Wave propagation is a phenomenon resulting from high transient loadings where the duration of the load is in µ seconds range. In aerospace and space craft industries it is important to gain knowledge about the high frequency ... -
Wavelet Based Algorithms For Spike Detection In Micro Electrode Array Recordings
(2010-07-13)In this work, the problem of detecting neuronal spikes or action potentials (AP) in noisy recordings from a Microelectrode Array (MEA) is investigated. In particular, the spike detection algorithms should be less complex ... -
Wavelet Based Spectral Finite Elements For Wave Propagation Analysis In Isotropic, Composite And Nano-Composite Structures
(2009-04-02)Wave propagation is a common phenomenon in aircraft structures resulting from high velocity transient loadings like bird hit, gust etc. Apart from understanding the behavior of structures under such loading, wave propagation ... -
Weakly cemented granular materials: study at multiple length scales
Cemented granular systems are encountered at various scales in nature and artificially. We present an experimental study carried out on the structure and mechanical behaviour of weakly cemented granular materials. We study ... -
Wearable Sensors using Solution Processed 2D Materials
Wearable sensors, as the name implies, are devices that can be donned onto the body in order to continuously detect, monitor and analyze various signals generated by the subject and the immediate surroundings. Applications ... -
Weighted Average Based Clock Synchronization Protocols For Wireless Sensor Networks
(2016-07-12)Wireless Sensor Networks (WSNs) consist of a large number of resource constrained sensor nodes equipped with various sensing devices which can monitor events in the real world. There are various applications such as ... -
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 ... -
Weighted Norm Inequalities for Weyl Multipliers and Hermite Pseudo-Multipliers
(2018-05-30)In this thesis we deal with two problems in harmonic analysis. In the first problem we discuss weighted norm inequalities for Weyl multipliers satisfying Mauceri’s condition. As an application, we prove certain multiplier ... -
Weights of highest weight modules over Kac-Moody algebras
In this dissertation, broadly, we treat the weight-sets of arbitrary highest weight modules (uniformly) over all general complex Kac-Moody Lie algebras $\mathfrak{g}$, achieving the below. We obtain a uniform, explicit, ... -
Wetting and Frictional Properties of Hexagonal Boron Nitride with Atomic-Scale Defects and Roughness
Two-dimensional (2D) materials such as graphene, hexagonal boron nitride (hBN), and molybdenum disulfide (MoS2) have become materials of choice for applications spanning optoelectronics, atomically thin coatings, and ... -
Whisker Growth from Electrodeposited Sn Coatings - Developing Materials Science and Mechanics Based Insights
(2018-05-23)Pure Sn and Sn-alloys are widely used in electrical and microelectronic devices as protective layer to prevent oxidation of Cu conductors and also as a component of Pb-free, Sn-based solders. Sn coatings, typically 0.5-10 ... -
Who Spoke What And Where? A Latent Variable Framework For Acoustic Scene Analysis
(2016-09-15)Speech is by far the most natural form of communication between human beings. It is intuitive, expressive and contains information at several cognitive levels. We as humans, are perceptive to several of these cognitive ... -
Why only two ears? Some indicators from the study of source separation using two sensors
(Indian Institute of Science, 2005-02-10)In this thesis we develop algorithms for estimating broadband source signals from a mixture using only two sensors. This is motivated by what is known in the literature as cocktail party effect, the ability of human beings ... -
Wide Area Measurement Based Cyber-Attack Resilient Breaker Failure Protection Scheme
Breaker Failure Protection(BFP) is a backup protection that comes into action when the primary protection schemes are unable to clear the fault. In power systems, every component has a redundant version to avoid failures. ... -
Wide Band Gap Oxides as the Probes for Optical Based Sensing Applications
Temperature is a very critical and widely measured variable by both researchers and engineers. In this regard, most of the available temperature sensors are based on contact mode of operation. In this consideration, the ...
