Growth and Studies of Phase Transitions in Multifunctional Perovskite Materials
(2018-06-11)Crystal growth and characterization of few multifunctional materials with perovskite (ABX3) structure are discussed in this thesis. Efforts were made to modify the magnetic and electric behaviour of these materials by ... -
Growth Aspects And Phonon Confinement Studies On Ion Beam Sputter Deposited Ultra Thin Films
(2011-03-01)The broad theme of the present research investigation is on the preparation and characterization of the ultra thin films. The emerging field of nano science and technology demands the realization of different materials in ... -
Growth Kinetics And Electronic Properties Of Semiconducting Nanocrystals In The Quantum Confined Regime
(2009-03-04)Properties of nanocrystals are extremely sensitive to their sizes when their sizes are smaller or of the order of the excitonic diameter due to the quantum confinement effect. The interest in this field has been concentrated ... -
Growth of hole-conducting Cu2O & CuO semiconductors using CVD for next-generation electronic devices: Thin Films Transistors, Memristors, and Gas Sensors
Semiconducting oxides with visible-range transparency and high electrical conductivity have tremendous potential for transparent CMOS devices. Oxide semiconducting materials are a good choice for emerging transparent ... -
Growth of Semiconductor and Semiconducting Oxides Nanowires by Vacuum Evaporation Methods
(2018-04-12)Recently, there has been a growing interest in semiconductor and semiconducting oxide nanowires for applications in electronics, energy conversion, energy storage and optoelectronic devices such as field effect transistors, ... -
Growth, Structural And Physical Properties Of Certain Antimony Based III-V Diluted Magnetic Semiconductors
(2010-07-20)Semiconductor devices are the building blocks of electronics and communication technology in the modern world. The charge, mass and spin of charge carriers in the semiconductor devices lay the foundations of the technology ... -
Growth, Transport, Magnetic And Thermal Studies On Single Crystals Of Pr1-xPbxMnO3
(2009-06-17)Mixed valence manganites with the perovskite structure R1-xAxMnO3 (where R = La, Nd, Pr and A = Ba, Ca, Sr, Pb) have been a popular subject of contemporary research because of their interesting physical properties such as ... -
Guanylyl Cyclase C Regulation And Pathophysiology
(2015-02-26)The survival of the any living organism depends on its availability to communicate, and a breakdown of cellular signaling can have dire consequences such as uncontrolled cellular proliferations or even cell death. Environmental ... -
Guarding Terrain using k-Watchtowers
The discrete k-watchtower problem for a polyhedral terrain T in R3 with n vertices is to nd k vertical segments, called watchtowers, of smallest height, whose bottom end-points (bases) lie on some vertices of T, and ... -
Guessing And Compression : A Large Deviations Approach
(2011-04-01)The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ... -
Guidance Laws for Engagement Time Control
(2017-12-16)Autonomous aerial vehicles like missiles and unmanned aerial vehicles (UAVs) have attracted various military and civilian applications. The primary guidance objective of any autonomous vehicle is to reach the desired ... -
Guidance Laws For Impact Angle Constraints And Exo-Atmospheric Engagements
(2010-10-22)This thesis deals with development of guidance laws for advanced applications. Two class of guidance problems, namely, impact angle constrained guidance and pulsed guidance for exo-atmospheric engagements, are considered ... -
Gust Rejection in Insect Flight
Large commercial and military aircraft can fly in turbulent wind conditions except in extreme weather events like cyclones. Smaller man-made vehicles like Micro aerial vehicles (MAVs) and Nano aerial vehicles (NAVs) are ... -

Habitat Acoustics And Microhabitat Selection In An Ensiferan Assemblage Of A Tropical Evergreen Forest │
(2013-08-29)Several animals, both vertebrate and invertebrate, communicate using sound and they do so in a non-ideal medium, the habitat in which they live. As acoustic signals pass through the habitat, they suffer loss of information ... -
Hadwiger's Conjecture On Circular Arc Graphs
(2009-04-30)Conjectured in 1943, Hadwiger’s conjecture is one of the most challenging open problems in graph theory. Hadwiger’s conjecture states that if the chromatic number of a graph G is k, then G has a clique minor of size at ...
