Autonomous Orbit Estimation For Near Earth Satellites Using Horizon Scanners
(Indian Institute of Science, 2005-10-20)Autonomous navigation is the determination of satellites position and velocity vectors onboard the satellite, using the measurements available onboard. The orbital information of a satellite needs to be obtained to support ... -
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 ... -
Bacterial transformation of nitroaromatic compounds and its implicatins in detoxification
Nitroaromatic compounds form a major group of environmental pollutants because of their high toxicity, widespread use, and recalcitrance to microbial degradation. The studies incorporated in this thesis aimed at understanding ... -
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 ... -
Balloon-borne far infrared observations of galactic star forming regions
Stars are born predominantly within dense cores of giant molecular clouds having number densities > 10? cm?³. This premise is strongly supported by a wealth of observations showing that the hallmarks of newly formed ... -
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 Coverage using UAVs and Camera Sensors
With advancements in camera sensor technology, camera sensor networks are increasingly utilized for border surveillance. UAVs equipped with downward-facing cameras also serve as effective sensors, and their features, ... -
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 ... -
Basic studies on electromechanical power sources - Voltage transients, alternating current impedance and steady state discharge characteristics of magnesium-manganese dioxide dry cells and supplementary investigation on titanium-substrate cobalt oxide and magnetite anode development for electrosynthesis
The extended shelf life of high-energy primary batteries based on lithium, magnesium, and aluminum is primarily attributed to the presence of a protective passive film on the surface of the reactive metal anode. Evaluating ...
