Robust Non-convex Penalties for Solving Sparse Linear Inverse Problems and Applications to Computational Imaging
Sparse linear inverse problems require the solution to the l-0-regularized least-squares cost, which is not computationally tractable. Approximate and computationally tractable solutions are obtained by employing ... -
Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading
(2018-07-16)Opportunistic use of unused spectrum could efficiently be carried out using the paradigm of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is not using it. The secondary nodes detect this ... -
Robust Numerical Modeling of Adhesively-Bonded Joints for Safety Assessment of Vehicle Body Structures Subjected to Extreme Loading
Continuous adhesively-bonded joints can lead to stiffer vehicle body structures in contrast to conventional spot-welded steel sheet metal-based unitized vehicle body design. For a given target stiffness, adhesive bonding, ... -
Robust Partial Integrated Guidance And Control Of UAVs For Reactive Obstacle Avoidance
(2012-04-24)UAVs employed for low altitude jobs are more liable to collide with the urban structures on their way to the goal point. In this thesis, the problem of reactive obstacle avoidance is addressed by an innovative partial ... -
Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems
(2013-10-04)The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ... -
Robust Registration of Measured Point Set for Computer-Aided Inspection
(2018-03-22)This thesis addresses the problem of registering one point set with respect to another. This problem arises in the context of the use of CMM/Scanners to inspect objects especially with freeform surfaces. The tolerance ... -
Robust Risk Minimization under Label Noise
In the setting of supervised learning, one learns a classi fier from training data consisting of patterns and the corresponding labels. When labels of the examples in training data have errors, it is referred to as label ... -
Robust Station-keeping and High-Precision Attitude Control for a Spacecraft on Sun–Earth L1 Halo Orbit
The halo orbits around the Sun-Earth L1 Lagrange point form an ideal location for deploying a solar observation spacecraft as they offer uninterrupted, long-duration visibility of the Sun. However, the complex orbital and ... -
Robust Techniques Of Language Modeling For Spoken Language Identification
(2009-07-23)Language Identification (LID) is the task of automatically identifying the language of speech signal uttered by an unknown speaker. An N language LID task is to classify an input speech utterance, spoken by an unknown ... -
Robust, Energy‐efficient Distributed Inference in Wireless Sensor Networks With Applications to Multitarget Tracking
The Joint Directors of Laboratories (JDL) data fusion model is a functional and comprehensive model for data fusion and inference process and serves as a common frame of reference for fusion technologies and algorithms. ... -
Robustness of Neural Activity Dynamics in the Medial Entorhinal Cortex
Biological systems exhibit considerable heterogeneity in their constitutive components and encounter stochasticity across all scales of analysis. Therefore, central questions that span all biological systems are: (a) How ... -
A role for the cohesin complex in subtelomeric gene silencing in Saccharomyces cerevisiae
Chromatin is a dynamic structure which reorganizes to support numerous chromosomal processes. Various histone and non-histone proteins are involved in chromatin organization. One such group of non-histone proteins, known ... -
Role of 3D-organization of the X-inactivation centre in imprinted X-chromosome inactivation
The connection between 3D-genome organization and genome regulation is one of the fundamental questions in modern biology. In a nucleus, the genome is organized through different layers of 3D-organization such as ... -
Role of Activin A Signaling in Breast Cancer
(2017-11-22)Activin-A is a member of transforming growth factor-β (TGF-β) superfamily of cytokines which includes TGF-βs, Activins, Nodal, bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs) and anti-Mullerian ... -
Role of Aerosols in Modulating the Intraseasonal Oscillations of Indian Summer Monsoon
(2017-12-05)In this thesis, we have presented a systematic analysis of the change of cloud properties due to variation in aerosol concentration over Indian region using satellite observations, and Weather Research and Forecasting Model ... -
Role of AMP-Activated Protein Kinase in Cancer Cell Survival under Matrix-Deprived Conditions
(2018-07-19)Cancer progression is a multi-step process requiring cells to acquire specific properties that aid the neoplastic growth. One such property is the ability to survive in the absence of matrix-attachment, a critical necessity ... -
Role of an RNA Polymerase Interacting Protein, MsRbpA, from Mycobacterium smegmatis in Phenotypic Tolerance to Rifampicin
Rifampicin is a non-competitive inhibitor of bacterial RNA polymerase (RNAP). The knowledge about the mechanism of action of this drug has emanated from the genetic and the biochemical studies carried out on Escherichia ...
