DYNAMIC ADAPTATION OF BANDWIDTH GRANULARITY FOR MULTIPATH ROUTING IN ELASTIC OPTICAL OFDM-BASED NETWORKS
… the work to reduce the fragmentation effects by dynamically updating and controlling the minimum bandwidth allocation granularity. that serves the light path requests over multipath networks. We adopt linear and nonlinear dynamic mechanisms, which are denoted as LDAɡ and NLDAɡ that are …

Online Voltage Stability Monitoring and Control Using Limited Synchrophasor Measurements
… Equivalent (TE) based method considering voltage dynamic mechanisms. To extend the model from one load bus to a critical load center, Optimal Power Flow-Loading limit (OPF-LI) is developed to assess the voltage stability margin. To utilize limited available PMU measurements, State Calculator (SC) …

Dynamics of Hairpin Ribozyme
… uses single molecule spectroscopy to study the dynamics of hairpin ribozyme---an enzymatic RNA molecule capable of cleaving phosphodiester linkage. RNA controls key processes of gene expression. Ribozymes can catalytically edit precursor RNA message transcribed from DNA, the edited RNA then …

An investigation into the design of surface piercing super cavitating hydrofoils
The fluid-dynamic design of hydrofoils to support marine crafts at high speeds has received growing interest in recent years. Physics involved in the design of high-speed surface-piercing hydrofoils is complex involving three different fluid phases (air, water and vapor) and complex fluid dynamic …

Essays on Prospect Theory, Dynamic Contracting and Procurement
… relations evolve over time, by studying a dynamic variant of the classical two-type-buyer contract in mechanism design. It is less trivial and more interesting if the utility determinant (or utility type) is not fixed or completely random, and fair assumptions are that it is either …

Highly Constrained Kinetic Models for Quantitative Single-Cell Gene Expression Analysis
… outcomes arises from both regulatory mechanisms and stochastic events, making it essential to understand transcription dynamics to better grasp heterogeneity within gene regulatory networks. This dissertation investigates transcription from a kinetic biochemical perspective, leveraging …

A body force model for cavitating inducers in rocket engine turbopumps
… and characterization of the governing uid dynamic mechanisms. Building on body force models of gas turbine compressors for compressor stability, the model introduces an additional force component, the binormal force, to capture the strong radial flows observed in inducer ow fields. The body …

Modeling and Measuring Affordability as Fitness
… search paths followed – it is path dependent. Dynamic mechanisms create, dictate and maintain path dependence. Initial conditions define the start and direction of a path. During subsequent design steps, positive feedback influences the designer to continue on that path. This dissertation …

Nonlinear Dynamical Analysis Of Microvascular Red Blood Cell Flow
… cell (RBC) flow is an enormously complex and dynamically variable process. Variations appear as temporal fluctuations within vessels, and spatially, along or between vessels in a network. These variations occur on many different time scales and highlight microcirculatory regulation at many …

The Principles and Applications of Plasmid Transfer in Microbial Communities
… decoupling is lacking. Statistical mechanisms have been commonly hypothesized to explain such decoupling. Here, I proposed that dynamic mechanisms, mediated by horizontal gene transfer (HGT), also enable the independence of functions from the compositions of microbial communities. I …
