Autonomous Spacecraft Mission Planning And Execution In A Petri Net Framework
(2014-08-01)Presently, most spacecraft are controlled from ground involving activities such as up-linking the schedule of daily operations and monitoring health parameters. These activities lead to a cognitive overload on human ... -
Availability, Allocation and Sharing of Water in a River Basin
(2018-06-18)The economic growth and the increase in population has led to an increased demand for water for various purposes such as domestic consumption, irrigation, industrial use, power generation, navigation, recreation, and ... -
Average Reward Actor-Critic with Deterministic Policy Search
The average reward criterion is relatively less studied as most existing works in the Reinforcement Learning literature consider the discounted reward criterion. There are few recent works that present on-policy average ... -
Axially Homogeneous Turbulent Convection at High Rayleigh Numbers : Scaling Laws for Flux and Spectra
(2018-05-30)Natural turbulent convection studies encompass a wide range of flows occurring in nature, for example, atmospheric and oceanic flows, con-vection in the Earth’s mantle, convection in the stars and also in many engineering ... -
Axially Symmetric Equivalents Of Three-Dimensional Rf Ion Traps
(2013-09-13)This thesis presents axially symmetric equivalents of three-dimensional rf ion traps. Miniaturization in mass spectrometry has focused on miniaturizing mass analyzers. Decrease in mass analyzer size facilitates reduction ... -
Axisymmetric Contact Problems In Composite Elastic Media

Aβ42-mediated dendritic spine loss in an in-vitro model of Alzheimer’s disease
The results from this study establish the molecular mechanism underlying the Aβ42-mediated dendritic spine loss observed in the APP/PS1 mouse model of AD. Further, this study highlights the role of Aβ42 in altering the ... -
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 ... -
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 ...
