State and Parameter Estimation in Water Distribution Systems
Water Distribution Systems (WDS) are one of the most important infrastructures in a society, which has a direct impact on human lives. Water authorities around the world are expected to supply the required amount of water ... -
Studies on Non-Destructive Evaluation of Friction Stir Weld Discontinuities with Probability of Detection
Friction stir welding(FSW) is a solid-state metal joining process which is currently being considered for joining of aerospace components. The zones associated with FSW are distinctly different from the fusion weld and ... -
Improved laboratory and computational models for thermal core–mantle interaction
The Earth's magnetic field is generated by thermochemical convection within its fluid outer core. The near-stationary high-latitude magnetic flux concentrations in the present day field indicate that convective ... -
Integration of Functional Oxide Films on Semiconducting Substrates
System-on-chip (SoC) applications have attracted the attention of the modern community due to their ability to facilitate various functionalities within a single device which can meet the requirements of day-to-day life. ... -
Regulation of RecA nucleoprotein filament stability by RecX and the effects of RecA-membrane interaction on the activities of RecA in mycobacteria
E. coli RecA is a multifunctional protein known to be associated with the cell membrane, forming foci often located at the cell poles, which gets redistributed along the length of the cell during SOS response. Several lines ... -
Raman Study of gated devices in two-dimensional materials and pressure effects
This thesis presents Raman study of 2D materials of contemporary interests: 2H-MoTe_2, type-II Weyl semimetal (T_d-MoTe_2), structurally anisotropic semiconductors (1T'-ReX_2 (X=S, Se)) and Mott insulator (FePS_3) under ... -
Designing Solutions to Counter the Attacks in Mobile Ad hoc Networks
The open medium, dynamic topology and distributed operation in Mobile Ad hoc Networks (MANET) leads to high risks. Many solutions are proposed to protect a MANET from attacks, ranging from attack identification to ... -
Architecting Conjugated Molecules for Band Gap Engineering & Photostability
Organic photovoltaic (OPV) modules are flexible, light weight, transparent and thin compared to other emerging photovoltaic technologies, making them well-suited for applications ranging from solar windows to fabrics. A ... -
Reconfigurable Accelerator for High Performance Application Kernels
Accelerating high performance computing (HPC) applications such as dense linear al- gebra solvers, mesh computations, stencil computations requires exploiting parallelism that is resident in loops. Typically these loops ... -
Conductance Fluctuations in High-mobility Graphene Field Effect Transistors
