Optical Tweezers To Probe And Manipulate Soft, Nano And Bio Systems
(2013-01-31)Statistical physics in soft matter systems, physical properties of bio-inspired systems and the mechanical manipulations of nano-systems have been studied using optical tweezers to form the basis of this doctoral Thesis. ... -
Optical WDM Systems for Multi-point Distribution of Hybrid Signals in Phased Array Radar Applications
(2018-07-16)Photonics and Optical techniques have advanced recently by a great extend to play an important role in Microwave and Radar applications. Antenna array of modern active phased array radars consist of multiple low power ... -
Optical, AC Conductivity, NMR and Raman Studies of Alkali Borogermanate Glasses
(2017-11-22)Physical properties of materials and their constituents are interrelated. Though the basic structural unit involved also plays a role in deciding the properties, this can be manipulated to a certain extent, by carefully ... -
Optical, Electrical and Photo-physical Investigations of Cd(Hg)Te Nanostructures Synthesized by Solvothermal Method
The thesis investigates the optical, photo-physical, and electrical properties of CdTe and HgCdTe nano- and micro-structures synthesized by hydrothermal/solvothermal technique. Application oriented studies like fluorescence ... -
Optical, Structural and Mechanical Characterization of Ultrafast Laser Inscribed Chalcogenide Waveguides
In recent years, chalcogenide glasses have established their usefulness as attractive candidates for the fabrication of all-optical devices and mid infra-red lasers. These glasses possess low phonon energy and hence high ... -
Optimal Amplify-And-Forward Relaying For Cooperative Communications And Underlay Cognitive Radio
(2017-08-21)Relay-assisted cooperative communication exploits spatial diversity to combat wireless fading, and is an appealing technology for next generation wireless systems. Several relay cooperation protocols have been proposed in ... -
Optimal Code Constructions for Some Multi-sender Index Coding Problems
An instance of the multi-sender index coding problem consists of a set of senders collectively having all the messages demanded by a set of receivers. Each receiver knows a subset of messages a priori, called its side ... -

Optimal Control of Information Epidemics in Homogeneously And Heterogeneously Mixed Populations
(2017-09-23)Social networks play an important role in disseminating a piece of information in a population. Companies advertising a newly launched product, movie promotion, political campaigns, social awareness campaigns by governments, ... -
Optimal Control Of Numerical Dissipation In Modified KFVS (m-KFVS) Using Discrete Adjoint Method
(2010-06-04)The kinetic schemes, also known as Boltzmann schemes are based on the moment-method-strategy, where an upwind scheme is first developed at the Boltzmann level and after taking suitable moments we arrive at an upwind scheme ... -
Optimal Control Problems In Communication Networks With Information Delays And Quality Of Service Constraints
(Indian Institute of Science, 2005-11-10)In this thesis, we consider optimal control problems arising in high-speed integrated communication networks with Quality of Service (QOS) constraints. Integrated networks are expected to carry a large variety of traffic ... -
Optimal Guidance Of Aerospace Vehicles Using Generalized MPSP With Advanced Control Of Supersonic Air-Breathing Engines
(2016-07-11)A new suboptimal guidance law design approach for aerospace vehicles is proposed in this thesis, followed by an advanced control design for supersonic air-breathing engines. The guidance law is designed using the newly ... -
Optimal Location of Distributed Generation to Reduce Loss in Radial Distribution Networks
(2018-06-26)Power losses are always a cause of worry for any power grid. In India, the situation is even worse. Though recent reports by Ministry of Power shows that Aggregate Technical and Commercial losses (AT &C losses) have come ... -
Optimal Mechanisms for Selling Two Heterogeneous Items
(2018-07-04)We consider the problem of designing revenue-optimal mechanisms for selling two heterogeneous items to a single buyer. Designing a revenue-optimal mechanism for selling a single item is simple: Set a threshold price based ... -
