Online Consumer Behaviour in Low Involvement Products: Cognitive Attributes and Purchase Behaviour
The internet has created fundamental shifts in business and consumer behaviour, akin to the industrial revolution of the 1800s. The internet serves as a ubiquitous and limitless information platform, and is leading to ... -
Online Learning and Simulation Based Algorithms for Stochastic Optimization
(2018-03-07)In many optimization problems, the relationship between the objective and parameters is not known. The objective function itself may be stochastic such as a long-run average over some random cost samples. In such cases ... -

Opacity and its Trade-offs with Security in Linear Dynamical Systems
Opacity is notion of privacy that is well-studied in computer science and discrete-event systems. In our work, we extend the opacity notion to linear dynamical systems. Opacity describes an eavesdropper’s inability to ... -
Operating System Support for Efficient Virtual Memory
Computers rely on the virtual memory abstraction to simplify programming, portability, physical memory management and ensure isolation among co-running applications. However, it creates a layer of indirection in the ... -
Operation of Three Phase Four Wire Grid Connected VSI Under Non-Ideal Conditions
(2018-04-12)The necessity to incorporate renewable energy systems into existing electric power grid and need of efficient utilization of electrical energy are growing every day. A shunt connected Voltage Source Inverter(VSI) capable ... -
Operationalising Sustainability in Smart Manufacturing Systems: A Model-Based Approach
This dissertation addresses the need for sustainability in manufacturing industries by leveraging digitalization and Model-Based Systems Engineering (MBSE). The research presents a comprehensive framework for operationalizing ... -
Operator Theory on Symmetrized Bidisc and Tetrablock-some Explicit Constructions
(2018-07-26)A pair of commuting bounded operators (S; P ) acting on a Hilbert space, is called a -contraction, if it has the symmetrised bides = f(z1 + z2; z1z2) : jz1j 1; jz2j 1g C2 as a spectral set. For every -contraction (S; P ), ... -
Opportunistic Beamforming and Asymptotic Throughput Analysis of Hybrid Analog-Digital mmWave Multi-User MIMO Systems
In this thesis, we address the problem of large training/feedback overhead and the requirement of computationally intensive algorithms to determine the phase angles of the analog precoder for downlink data transmission ... -
Optical and behavioural tools to investigate the neural correlates of learning and memory
Events in our everyday life are encoded as memories that can be consciously recollected and remembered, although our ability to retrieve the specific details associated with these events diminish with time. Such losses ... -
Optical and Electrical Studies of Hybrid Nanomaterial Composites Based on Noble Metal Nanostructures
Localized surface plasmon resonance (LSPR) in noble metal nanoparticles like gold (Au) and silver (Ag) results in enhancements in optical absorption and scattering by the nanoparticles, accompanied by a dramatic ... -
Optical and Optothermal route towards dynamic nanomanipulation in fluids
Manipulation of materials with light has led to significant breakthroughs in biology, material science and soft condensed matter physics. Conventional optical tweezer, which is effectively a tightly focused laser beam, can ... -
Optical And Structural Investigations Of Defects In CdZnTe(Zn ~ 4%) Crystals
(2013-06-12)The CdTe family members (in particular CdZnTe) remain the substrate of choice for epitaxial growth of HgCdTe for use in high performance infrared (IR) detectors and focal plane arrays. This is the case despite advances in ... -
