Development and Applications of Multi-Objectives Signal Control Strategy during Oversaturated Conditions
… are defined and categorized to address oversaturation problematic scenarios. A timing procedure was then developed using the principles of oversaturation timing in cycle selection, split allocation, offset design, demand overflow, and queue allocation in non-critical links. Three regimes …

Improving traffic signal performance using high-resolution data
… to alleviate the detrimental impacts caused by oversaturation. In this research, our focus is to mitigate two types of detrimental effects, signal phase failure with residual queue and downstream queue spillover. Building upon the previous work on the oversaturation severity indices, a …

On the Use of Grouped Covariate Regression in Oversaturated Models
… difficulty, with various means of combating the oversaturation. However, these techniques can be tricky to implement well, difficult to interpret, and unstable. What is proposed is a technique that takes advantage of the natural clustering of variables that can often be found in biological and …

The Impact of Housing Insecurity on Community Health Outcomes: Exploring Collective Community Solutions and Housing Models in The Western Addition
… stable, affordable homes? How can we prevent an oversaturation of services as a solution to community problems? How do we work with communities where Maslow's hierarchy of needs are severely compromised? How can we create consistent housing models for public and mixed income tenants on a national …

Late quaternary climate changes and landscape evolution in the Northwest Himalaya : geomorphologic processes in the Indian Summer Monsoon Domain
… monsoon phases prevents fluvial incision due to oversaturation the fluvial sediment-transport capacity. In contrast, weaker monsoons result in a lower sediment flux that allows incision in the low-elevation parts of the Sutlej River.

MASTraf: a decentralized multi-agent system for network-wide traffic signal control with dynamic coordination
… fluctuations, rapid changes in traffic demands, oversaturation, the occurrence of incidents, and adverse weather conditions, among others, significantly impact the traffic network operation in ways that current control systems cannot always cope with. On the other hand, strategies for traffic …

Approximate solutions for multi-server queuing systems with Erlangian service times and an application to air traffic management
… and high utilization, including occasional oversaturation. Conditions such as these cannot be addressed with existing methodologies. We focus on M(t)/G(t)/n(t)/n(t) + q systems that can be approximated fairly well by M(t)/E&(t)/n(t)/n(t) + q systems. The latter have a large number of system …

First principles simulation of amorphous silicon bulk, interfaces, and nanowires for photovoltaics
… is varied from 7% (undersaturation) to 18% (mild oversaturation). In the case of mild over saturation, the mid-gap states arise exclusively from an increase in the density of strained Si-Si bonds. Analysis of our structures shows the extra H atoms in this case form a bridge between neighboring …

Particle Detachment in Single-Phase and Two-Phase Flows in Porous Media
… state of fines were also derived in this thesis. Oversaturation means that particles begin to detach as soon as the flow starts. In the undersaturated case, particle detachment occurs only with further increase in detaching torque or decrease in attaching torque. The derived models allow …

Applications of Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) in pharmaceutical analysis
… of dissolved gases in solution, leading to gas oversaturation and outgassing of the solvent, changing the solvent system's compressibility, and reducing the velocity of sound in the solvent. In the results section of this thesis, Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) is …

A conceptual framework for using feedback control within adaptive traffic control systems
Existing adaptive traffic control strategies lack an effective evaluation procedure to check the performance of the control plan after implementation. In the absence of an effective evaluation procedure, errors introduced in the system such as inaccurate estimates of arrival flows, are carried …

Development and manufacture of novel amorphous Itraconazole drug products using quality by design principles
… ITZ concentration. Shift in baseline was due to oversaturation and/or presence of bubbles. Only the ITZ concentration exhibited a statistically significant effect on the responses (absorbance and L*). DoE 2 explored the effect of screw speed and feed rate factors on the responses. Out of the ten …
