On Design and Analysis of Energy Efficient Wireless Networks with QoS
(2018-06-13)We consider optimal power allocation policies for a single server, multiuser wireless communication system. The transmission channel may experience multipath fading. We obtain very efficient, low computational complexity ... -
On Dimensional Parameters Of Graphs And Posets
(2013-06-21)In this thesis we study the following dimensional parameters : boxicity, cubicity, threshold dimension and poset dimension. While the first three parameters are defined on graphs, poset dimension is defined on partially ... -
On Flow Physics of Spinning Samaras
A particular form of winged seed (samara) dispersal technique adopted by nature uses autorotative (unpowered rotation of the wing generating thrust force against gravity) descent; for eg. in Maple and Mahagony trees. ... -
On Generalized Measures Of Information With Maximum And Minimum Entropy Prescriptions
(2008-01-29)Kullback-Leibler relative-entropy or KL-entropy of P with respect to R defined as ∫xlnddPRdP , where P and R are probability measures on a measurable space (X, ), plays a basic role in the definitions of classical information ... -
On Hypergeometric solutions of Feynman integrals using Mellin-Barnes Integrals with Applications
Experimental measurements of physical observables in particle colliders rely on high-precision theoretical calculations to validate the predictions of any theoretical model and detect signals of new physics. These theoretical ... -
On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both in engineering applications and natural phenomena. A laminar-turbulent transition process is inherent to its development involving ... -
On Learning and Lower Bound Problems Related to the Iterated Matrix Multiplication Polynomial
The iterated matrix multiplication polynomial (IMM) of width w and length d is the 1x1 entry in the product of d square matrices of size w. The w^2d entries in the d matrices are distinct variables. In this thesis, we study ... -
On Learning k-Parities and the Complexity of k-Vector-SUM
(2018-02-06)In this work, we study two problems: first is one of the central problem in learning theory of learning sparse parities and the other k-Vector-SUM is an extension of the not oriousk-SUM problem. We first consider the problem ... -
On Leveraging Dynamic Processes in Large Social Networks for Smart Cities
The concept of smart city which began as being synonymous with electronically networked community underwent significant changes with the growth in mobile devices and social networking. This expanded the outlook of smart ... -
On Linear Codes in Projective Spaces
The projective space $\mathbb{P}_q(n)$ of order $n$ over a finite field $\mathbb{F}_q$ is defined as the collection of all subspaces of the ambient space $\mathbb{F}_q^n$. The Grassmannian $\mathcal{G}_q(n, k)$ is the set ... -
On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(2017-07-07)We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chi-squared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ... -
On mechanisms and conformational dynamics of Drug:H+ Antiporters
Multidrug efflux is an active transport process involving energy consumption to drive antibacterial compounds out of cells. This is performed either through primary active transport, where chemical energy, such as hydrolysis ... -
On Media-Based Modulation for Wireless Communications
Traditionally, symbols chosen from complex modulation alphabets such as QAM and PSK are used to convey information bits, and complex fades introduced by the channel are viewed as detrimental effects that cause amplitude ... -
On Modeling Of Constrained Piezoelectric Thin Films For Structural Health Monitoring
(2010-01-01)The behaviour of a free-standing thin film differs from that of a film surface-bonded or embedded due to the boundary constraints. A general dearth of analytical models, in regard to prediction of the operational competence ... -
On Network Coding and Network-Error Correction
(2018-04-24)The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information flow networks. Network coding makes use of the fact that unlike physical commodities, ... -
On Orthogonal Time Frequency Space Modulation for Wireless Communications
Future wireless communication systems are envisioned to support diverse requirements that include high mobility application scenarios such as high-speed trains, and vehicle-to-vehicle and vehicle-toinfrastructure communications. ... -

On Plug-and-Play Regularization using Linear Denoisers
The problem of inverting a given measurement model comes up in several computational imaging applications. For example, in CT and MRI, we are required to reconstruct a high-resolution image from incomplete noisy measurements, ... -
On Reduced-State Optimal Scheduling for Decentralized Medium Access Control of Wireless Data Collection Networks
In the Internet of Things (IoT), devices such as sensors and actuators will almost invariably be connected to the Internet via wireless networks. The sensor and actuator devices in such systems will be resource challenged ...
