Low-Cost And Reliable Integrated Hardware And Software Framework For Remotely Operated Water Release From Storage Units, Vivek Verma

FIU Electronic Theses and Dissertations

The main contribution of this research is towards the broader area of water management that can be used for multiple purposes. For instance, floods can be mitigated using a novel approach based on the integrated dynamic management of water storage units such as reservoirs, wetlands, and ponds. This approach will enable adaptive water release from storage units hours or days ahead of rainfall events, thereby maximizing storage capacity and minimizing flooding.

This approach can be implemented by retrofitting water storage units using siphon hydraulic systems and are remotely controlled in an integrated manner using the decision support system. To make …

Enabling Robust Distributed Real-Time Hybrid Simulation Method And Expanding Its Applications In Floating Wind Turbine Systems, Mehmet Cinar

Masters Theses

Real-time hybrid simulation (RTHS), which integrates physical experiment and numerical simulation, plays an essential role in understanding the time-dependent behavior of structures when subject to hazardous loadings. On the other hand, RTHS might not yield accurate results for complex structural systems due to experimental and computational limitations. Distributed real-time hybrid simulation (dRTHS), which takes the advantage of distributed laboratory facilities using network communications, was proposed and proven to address some limitations in RTHS. During dRTHS, Internet delay due to the network communication is added to the actuator delay in RTHS, which may cause inaccurate results or even unstable tests. To …

Travel Time Estimation On Urban Arterials - A Real Time Aspect, Jingcheng Wu

Theses and Dissertations

This dissertation attempts to develop simple and direct approaches to estimate the vehicle queue length and travel time along signalized arterial links for real-time traffic operations. This dissertation is the first to demonstrate a process using vehicle trajectory data to generate detector volume, speed and time occupancy data, along with the generalized flow rate, density and space mean speed data. This approach minimizes detector over-counting and miss-counting issues. The detection zone can be of any shape or size and at any location along the trajectory. The relationships among detector volume, speed and time occupancy along signalized arterials are analyzed theoretically …

Real-Time Hybrid Simulation With Online Model Updating, Adam Mueller

Masters Theses

Hybrid simulations have shown great potential for economic and reliable assessment of structural seismic performance through a combination of physically tested components, called the experimental substructure, and numerically simulated components, called the numerical substructure. Current hybrid simulation practices often use a fixed numerical model without considering the possible availability of a more accurate model obtained during hybrid simulation through an online model updating technique. To address this limitation and improve the reliability of numerical models in hybrid simulations, this study describes the implementation of an online model updating method in real-time hybrid simulation (RTHS). The Unscented Kalman Filter (UKF) was …

A Real-Time Offset Transitioning Algorithm For Coordinating Traffic Signals, Darcy M. Bullock, Montasir Abbas

Darcy M Bullock

This report introduces an adaptive real-time offset transitioning algorithm that can be viewed as an integrated optimization approach designed to work with traditional coordinated-actuated systems. The Purdue Real-Time Offset Transitioning Algorithm for Coordinating Traffic Signals (PRO-TRACTS) adds to the controllers the ability to adaptively change their offsets in response to changes in traffic pattern, providing an intermediate solution between traditional coordinated-actuated control systems and adaptive control systems. To facilitate implementation, a new National Transportation Communication for ITS Protocol (NTCIP) object for capturing detector actuation at the controller’s level is defined in this report. The unique cycle-based tabulation of volume and …
