B, N containing π- conjugated systems: room temperature phosphorescence, fullerene complexation, and cell differentiation
Advances in heteroatom (B, N, and B-N) incorporated π-conjugated systems have attracted considerable attention because of their desirable properties and widespread applications. Substitution of isoelectronic B–N units for ... -
Bacterial cellular heterogeneity in inducible gene expression and drug susceptibility
Biological processes are inherently noisy, and such stochasticity can result in significant cell to cell variability in isogenic bacterial populations. Functionally, cellular heterogeneity can have significant impact on ... -
Balancing Money and Time for OLAP Queries on Cloud Databases
(2017-12-16)Enterprise Database Management Systems (DBMSs) have to contend with resource-intensive and time-varying workloads, making them well-suited candidates for migration to cloud plat-forms { specifically, they can dynamically ... -
Ballast-Free Variable-Speed Generation for Standalone and Grid-Connected Micro-Hydel Power Plants
(2017-12-12)Concerns about climate change brought about by the increasing usage of fossil fuels has made it imperative to develop sustainable energy usage based on renewable sources. Micro-hydel plants are an important source of ... -
Band-matched transport layers and intrinsically stable perovskite solar cells for application to perovskite Si tandem cells
Hybrid perovskite/silicon tandem solar cells offer low-cost alternatives to the commercially established silicon solar cells. In this thesis, we present the material and device optimizations of the subcells that can be ... -
Bandit Algorithms: Fairness, Welfare, and Applications in Causal Inference
We study regret in online learning from a welfarist perspective and explore an application of bandit algorithms in causal inference. We introduce Nash regret, which measures the difference between the optimal action ... -
Barrier Function Inspired Reward Shaping in Reinforcement Learning
Reinforcement Learning (RL) has progressed from simple control tasks to complex real-world challenges with large state spaces. During initial iterations of training in most Reinforcement Learning (RL) algorithms, agents ... -
Batch Processsor Scheduling - A Class Of Problems In Steel Casting Foundries
(2010-09-15)Modern manufacturing systems need new types of scheduling methods. While traditional scheduling methods are primarily concerned with sequencing of jobs, modern manufacturing environments provide the additional possibility ... -
Battery Buffered Stiff Micro Grid Structure For A Variable Speed Slip Ring Induction Machine Based Wind Generation System
(2010-04-12)Electric power has become a basic necessity of human life. The major share of electric power comes from fossil fuel which results in global warming and pollution. A share of generated power comes from nuclear power which ... -
Battle of Bandits: Online Learning from Subsetwise Preferences and Other Structured Feedback
The elicitation and aggregation of preferences is often the key to making better decisions. Be it a perfume company wanting to relaunch their 5 most popular fragrances, a movie recommender system trying to rank the most ... -
Bay of Bengal Freshwater in the tropical Indian Ocean
The annual total continental runoff into the Bay of Bengal (BoB) is more than half the runoff into the entire tropical Indian Ocean. The net freshwater (FW) content in the Bay of Bengal mixed layer increases from a minimum ... -
Bayes Optimal Feature Selection for Supervised Learning
(2018-02-18)The problem of feature selection is critical in several areas of machine learning and data analysis such as, for example, cancer classification using gene expression data, text categorization, etc. In this work, we consider ... -
Bayesian Accelerated Life Testing of Series Systems
(2018-01-18)Consider life testing of J-component series systems that are subjected to stress levels that are steeper than that at normal usage condition. The objective of performing such life tests, commonly known as Accelerated Life ... -

Bayesian implicit filters for the analysis of numerically stiff structural dynamic state space models
This thesis reports on combined experimental and computational investigations conducted on problems of state and combined state and parameter estimation applied to vibrating engineering structures. The standard dynamic ... -
Bayesian Nonparametric Modeling of Temporal Coherence for Entity-Driven Video Analytics
(2018-05-14)In recent times there has been an explosion of online user-generated video content. This has generated significant research interest in video analytics. Human users understand videos based on high-level semantic ... -
Bayesian Techniques for Joint Sparse Signal Recovery: Theory and Algorithms
This thesis contributes new theoretical results, solution concepts, and algorithms concerning the Bayesian recovery of multiple joint sparse vectors from noisy and underdetermined linear measurements. The thesis is written ... -
Beamforming and Target Tracking Methods for Active RF Phased Array Seekers
The end game guidance and control of an interceptor for neutralization of a hypersonic vehicle or a maneuvering aerial target is a challenging problem. This problem can be addressed in two ways: through faster autopilot ...
