Piezoelectric Micromachined Ultrasound Transducers : From Design to Applications
(2018-06-21)Ultrasonic sensors are well known for various applications such as NDT, ultrasound imaging, and proximity sensing. Conventional ultrasound transducers are bulky, work at notoriously high voltages, and consume significant ... -
Planar Fault Energies in L12 Compounds
High temperature metallic structural materials, such as Ni-base superalloys owe their strength to a two-phase microstructure consisting of an fcc matrix strengthened by intermetallic A3B type precipitates. The performance ... -
Plasmon Phonon Coupled Dynamics of Nanocrystalline Structures
This thesis is an attempt to understand the characteristics and responses of plasmon phonon coupled dynamics in nanocrystalline structures. An energy based Lagrangian formulation is developed with fundamental field quantities ... -
Plastic Deformation During Indentation Of Crystalline And Amorphous Materials
(2013-06-10)Indentation hardness, H, has been widely used to characterize the mechanical properties of materials for more than a century because of the following advantages of this technique; (1) it requires small sample and (2) the ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Polymer-based investigations into the surface chemistry of some sulphide minerals and the beneficiation of a low grade siliceous copper ore
Tanzania is endowed with rich mineral deposits containing gold, tanzanite, diamond, coal, uranium, iron ore, gemstones with low grade of the sulphide minerals namely chalcopyrite and pyrite. It is the third largest producer ... -
Polyvinylidene fluoride (PVDF) based Nanocomposites with Multi-layered Architecture Containing Core-shell Nanomaterials for Electromagnetic Interference Shielding
With the emergence of smart electronic devices, we have witnessed a rapid surge in the growth and subsequent drive-in for the miniaturization of electronic interfaces. Any electronic gadget that transmits, distributes, or ... -
Pore Forming Toxins : Unravelling Oligomerization Pathways and Related Kinetics
Pore forming toxins are a class of proteins secreted from a wide variety of pathogens. These toxins are implicated in several diseases such as cholera, anthrax, tuberculosis and food poisoning. The toxin proteins are ... -

Posturing for Autonomous Digital Human Model
Digital Human Models (DHMs) are representations of humans in virtual environments that have applications in diverse disciplines. In the context of engineering design, DHMs are used to assess if a proposed design satisfies ... -
Potential Applications of Snail Mucus in Cartilage Repair and Fabrication of Porous 3D Scaffolds
Articular cartilage damage is a major challenge in orthopedics. This medical condition is exacerbated by the cartilage's inability to self-repair due to the non-vascularization of the tissue and many other factors. Several ... -
Power Loss Minimization for Drag Reduction and Self-Propulsion using Surface Mass Transpiration
(2017-11-29)The remarkable efficacy with which normal surface mass transpiration (blowing and suction) alters a given base flow to achieve a desired predefined objective has motivated several investigations on drag reduction, ... -
Pozzolanic Additives To Control Dispersivity Of Soil
(2016-11-13)The aim of the present investigation is to improve the geotechnical properties of dispersive soil by reducing their dispersivity after elucidating the important mechanisms controlling the dispersivity of the soils. ... -
Pragmatic Design of Compliant Mechanisms using Selection Maps
(2018-04-02)A pragmatic method for designing compliant mechanisms is developed in this thesis, by selecting among existing mechanisms one that may be modified as required. This method complements existing techniques by answering ... -
Precambrian ocean, life, and syn to post-collisional records in the Himalayas (Kumaun)
The Ph.D. thesis focuses on the central sector of the Himalayas, i.e., Kumaun. Here, an attempt has been made to understand the poorly understood genesis of magnesium carbonates (sparry magnesite) of the Precambrian ... -
Precipitate Growth and Coarsening in Ternary Alloys
(2018-08-20)We have studied precipitate growth and coarsening in ternary alloys using two different phase held models. The first one is a ternary extension of the classical Cahn-Hilliard (C-H) model in which both the phases are ... -
Precipitate Growth Kinetics : A Phase Field Study
(2011-08-30) -
Predictability of Nonstationary Time Series using Wavelet and Empirical Mode Decomposition Based ARMA Models
(2018-04-06)The idea of time series forecasting techniques is that the past has certain information about future. So, the question of how the information is encoded in the past can be interpreted and later used to extrapolate events ... -
Prediction Of Engineering Properties Of Fine-Grained Soils From Their Index Properties
(Indian Institute of Science, 2006-04-27)Prediction as a tool in engineering has been used in taking right judgement in many of the professional activities. This being the fact, the role and significance of prediction in geotechnical practice needs no emphasis. ...
