Show moreThe traffic safety issue especially in urban areas is getting increasingly severe due to the ever-growing travel demand which closely related to people’s basic necessities. As a part of the urban traffic network, the safety of the intersections in the urban area also reflects the efficiency and quality of the integrated urbanization level. Red light running at intersections has been a major safety concern in the United States. Because the red light running at intersection often results in a disproportionally higher percentage of injuries. From this point of view, the safety improvement of the urban intersections is imperative. The red light running photo enforcement has been designed to increase safety on streets by reducing the head-on, rear-end, and sideswipe crashes at intersections. Meanwhile, methods for intersection signal timing optimization in urban areas have been developed to reduce intersection delays. As a result of delay reductions, it is also important to analyze changes in vehicle crashes in order to gain a holistic understanding of traffic mobility and safety impacts. This study introduces an Empirical Bayesian (EB) before and after analysis method to evaluate the safety impacts of signal timing optimization on urban intersections with some intersections involved with red light running photo enforcement. Data on 842 signalized intersections are collected to calibrate the safety performance functions and to quantify the crash reduction effects before and after the signal timing optimization. Base on the EB method application, it is reviewed that a certain extent of safety enhancements is achieved as measured by crash type and severity level after intersection signal timing optimization and red light photo enforcement treatments.

Show moreInvestigating existing structures in the real world can help us know more about their characteristics, advantages, and disadvantages. In this thesis project, the investigation was performed on two real bridges named “Yale” Bridge, and “Valleyfield” Bridge. They were owned by the CN, one of the largest railway in the North American railroad industry. First, field testing of the bridges was performed by CN. Strain gauges (devices for indicating the strain of a material) and displacement transducers (devices for indicating movement) were placed on specific points on desired elements. Then the strain and displacement data for these specific points were recorded during the time trains were passing through the bridge. These devices record the data in voltage, so calibration constants must be applied to convert the data to stress & displacement units. After that, the bridges were modeled in “SAP2000” software, and the results were compared to the data recorded in the field. In the real world, these types of bridges are behaving something between the “Truss Model” and the “Frame Model”. Our aim is to know how they exactly behave and which model they are closer to. Results are showing that although the bridges are considered “Truss Bridges”, both of them are behaving more like a “Frame” Model than a “Truss” Model. In addition, the effect of the collision strut on L0U1 was investigated. Results shows that having this collision strut leads to the larger bending moment on L0U1 in comparison to lack of this member on the bridge. Finally, with respect to our results, “Adjustment Factors” for three different groups of diagonal, horizontal, and vertical members were provided in order to improve load rating analysis in the future.

Title: MECHANISMS OF FOAMING, EFFECTS, PREVENTION, AND CONTROL IN ANAEROBIC DIGESTION

Show moreAnaerobic digestion (AD) is an essential step to generate energy in the form of biogas from waste. Foaming during AD (AD foaming) is widespread phenomenon and leads to deterioration of the AD process and operation. In extreme conditions, AD foaming poses a significant safety risk and considerable economic impacts. It is, therefore, necessary to understand the fundamentals of AD foaming to develop effective strategies that can help minimize and prevent the foaming impacts. Several aspects of AD foaming have attracted considerable research attention, however, the focus has been mainly on site specific causes and prevention. The work leading to this thesis was aimed to provide a better understanding of the AD foaming problem, to identify the underlying mechanisms, causes and contributors of foaming and to come up with foam management strategies for full-scale plants. Full-scale cylindrical digester investigations did not identify non-biological factors such as organic loading rate (OLR), mixing, and primary to waste activated sludge (PS:WAS) solids ratio as primary causes of foaming, but foam-causing filaments such as G. amarae and M. parvicella were determined to be primary causes. No foaming was observed over the duration of the study, indicating absence of a primary foaming cause even though the suspected contributors to AD foaming were present. In the case of full-scale egg-shaped digesters (ESD), foaming and foam collapse events were observed over the duration of the study over both during filamentous foaming and non-foaming seasons, indicating that the primary foaming cause requires the contributors to be present. The results of this study demonstrate that ESDs foamed due to high mixing and G. amarae counts above the threshold level (log #6 intersections/mg VSS) in mixed liquor. In both types of digesters, total solids and temperature profiles showed that reducing mixing frequency did not significantly impact digester performance or the homogeneity of the digester contents. Hence, mixing intensity optimization could be an effective strategy in addition to primary cause reduction of foam causing filaments.

Title: A STRUCTURAL ANALYSIS FRAMEWORK FOR CONCRETE FACED ROCKFILL DAMS

Show moreConcrete Faced Rockfill Dams (CFRD’s) are commonly built around the world. As energy demands soar and construction methods evolve, the interest for construction of CFRD’s with larger heights has increased tremendously. However, because of construction of higher CFRD’s, some dams have experienced considerable fractures at the concrete faces. Well known cases include Campos Novos (Brazil), Barra Grande (Brazil), and Mohale (South Africa), where in some instances these cracks have led to dewatering of the reservoir to allow for the concrete slabs repairs. The development of these fractures may be attributed to the highly deformable rockfill body. In general, the state-of-the-art design of CFRD’s is mostly based on common practice rather than rigorous analysis procedures. And as such, cracking problems because of deformability of the rockfill may not be properly predicted unless a detailed analysis is performed. In this work, a new framework for analysis of CFRD’s is developed that is capable of predicting the possible concrete-facing failure. As a part of this framework, a comprehensive non-linear finite element analysis (FEA) scheme is developed to model the construction sequence, the contact interaction between the concrete facing and the rockfill body, and the impounding of the reservoir. As a case study, using the developed framework, the Kárahnjúkar CFRD (Iceland, 198m height) is analyzed, the results are validated by the field measurements, and mitigation measures suggestions are provided. This methodology, based on the results of the investigation, provides guidelines and establishes a framework for analysis of CFRD’s that can be used for design purposes.. Keywords: CFRD, Concrete Faced, Rockfill, Dam, Finite Element Analysis.

Show moreThis study analyzes and designs a logistics network for the distribution of four brands of passenger cars in the Great Lakes region. The study evaluates four types of distribution scenarios. Alternative 1 analyzes direct shipment method with only truck transportation mode from one distribution center located in the Chicago city to the cities in the Great Lakes region. Second alternative analyzes direct distribution method using multimodal transportation modes (railway and truck) from one distribution center to the cities included in this project. Third alternative analyzes peddling distribution method with only truck transportation mode from one warehouse to the project cities and the fourth alternative analyzes car distribution using direct shipment method with only truck transportation mode from two warehouses, where the main warehouse is located in Chicago city and the second warehouse is located in Indianapolis city. The analyses are conducted in order to determine the most cost-effective scenario for passenger car distribution in the Great Lakes region. The results of the study show that the most cost-effective scenario for passenger car distribution in the Great Lakes region includes using direct shipment method with multimodal transportation mode having one warehouse. However, this scenario has many uncovered sections such as we assumed that the warehouse and all destinations are located near to the railway yard and we do not need to transport cars from warehouse to the railway yard or from railway yard to the dealer by car huller truck/trailer. But in most of the time a railway yard and distribution center or a car dealership is not located in the same place or close to each other which in reality could increase the total cost for the logistics network. The second optimal cost provides the Alternative 1, which uses direct shipment method with only truck transportation mode and having one warehouse. This scenario is more practical and possible to use in reality without having significant changes in the total cost.

Show moreInventory control on a construction site is typically performed by an individual who regularly visits the storage area, directs personnel to forward components to the construction area, and reports to the site office about the quantities remaining in the storage area. Automating this process is expected to reduce mistakes and save significant time. In this study, the potential use of Bluetooth technology is investigated in construction inventory control as a tracking device. Commercial Bluetooth tracking devices were examined to understand the different devices’ capabilities and to extract usable attributes and characteristics about each brand. After an extensive examination of several brands, one of the commercial Bluetooth tracking devices with the most suitable capabilities was chosen for this study. The Android smartphone was selected to act as a scanner in the storage area and a basic workflow was designed around the Android smartphone and the Bluetooth tracking device. In addition, to improve the performance of the Bluetooth tracking device, it was paired with Near Field Communication (NFC) tags that expedited the material tracking process. The “hybrid” tracking device is introduced as the key element of the inventory control system and an Android smartphone is used as an in-house scanner that captures the tracking device’s information and sends it to a server for analysis. An automated inventory control system that is designed to use the proposed tracking device can contribute greatly to construction site productivity.

Title: METHOD TO STABILIZE SUSPENDED DECKS IN DOUBLE WALLED STORAGE TANKS

Show moreThe safe storage of natural resources, such as liquefied natural gas or propane, is essential to the public and companies that distribute these resources. Large diameter, double walled cylindrical storage tanks are the typical structure used to store these natural resources. One of the design factors that commonly govern the structural integrity of the tank is the design seismic response spectra. A component of the tank that is not given much consideration in the industry codes is the suspended insulated deck. The purpose of the deck is to provide a layer of insulation just above the liquid level of the product. This helps control the release of gases that boil off from the product. Despite this deck being made of thin plate material, this can be a considerable mass on large diameter tanks once the insulation and deck stiffeners are accounted for. The supports for the deck are typically one-half inch or sixteen millimeter square rods, which do not provide much lateral resistance. The concern this thesis investigates is what occurs to the suspended deck during an earthquake. By treating the outermost ring of rods as a moment frame, the summation of each rod’s lateral stiffness provides the total deck stiffness and natural period of the structure as a single-degree-of-freedom system. It is determined the standard design is likely to collide with other vital components of the tank under certain seismic events. In order to prevent the deck from potentially damaging these components, the conservative route is to increase the stiffness of the deck until the displacements are within an allowable range. viii This is done by installing a tank specific number of braced frames around the outer perimeter of the deck. The above procedure is a simple method to ensure there are no unexpected collisions between tank components. More time consuming methods, such as finite element analysis may show that the standard design can sufficiently withstand any collisions. However, the ability to provide a quick, easy solution with minimal added construction materials is a considerable advantage when ensuring the safety of the storage tank.
