Show moreIn the ever-growing travel demand, traffic congestion on freeways and expressways recurs more frequently at a higher number of locations and for longer durations with added severity. This becomes especially true in large metropolitan areas. Particular to the urban areas, excessive crowdedness caused by inefficient traffic control also results in urban street networks operating in near or over-saturated conditions, leading to unpleasant travel experience due to long delays at intersections. As a consequence, the recurrent traffic congestion on roadway segments and vehicle delays at intersections inevitably compromise energy efficiency, traffic mobility improvement, safety enhancement, and environmental impacts mitigation. All too often, neither restraining travel demand nor expanding system capacity is desirable and practical. Conversely, effectively utilizing the capacity of the existing transportation system has been increasingly thought of as the solution to congestion relief. With respect to the urban street networks, developing effective means for urban intersection signal optimization becomes essential to reduce intersection delays. Conventional signal timing optimization methods use historical traffic data and assume that traffic flows will remains unchanged after the implementation of new signal timing plans. Traffic flows are assumed to be constant, but in fact, when signal timing plans change, travel times for some travel routes will alter, which requires drivers in the network to adjust their choice of travel routes to arrive at the destinations, and result in redistribution of traffic in the network. Therefore, the effects of interactions between signal timing plans and traffic flows need to be explicitly taken into consideration. This study introduces a new methodology that jointly considers signal timing optimization and traffic assignment in an overall analytical framework that contains model formulations under assumptions consistent with real world situations. Such a framework is well suited for applications in real world cases. Specifically, the overall optimization framework is formulated as a bilevel optimization problem. In the proposed basic model, at the upper level, a traffic signal timing optimization problem for urban network is introduced to minimize system total travel time by optimizing signal green splits. At the lower level, a static user equilibrium problem is formulated for networkwide traffic assignment. In the vehicle delay estimation, the time-dependent stochastic delay model in the 2010 Highway Capacity Manual (HCM 2010) is employed and formulated as Variational Inequality constraints, what allow the state-of-the-art MPEC solver, GAMS/NLPEC, to solve the problem for a local optimal effectively and efficiently. The bi-level optimization model is first tested using a small network (the test network) and a computational experiment using a subarea network in the Chicago central district is conducted to assess the practicality of the model formulation in real world applications. In order to import more reality to the basic model and also consider the potential system benefit that comes from different signal phasing design, an enhanced model is developed based on the basic model by employing integer and binary variables. Formulating the problem with binary variables allows for the selection of proper phasing design. Heuristic solution methods are proposed and tested using the test network.

Title: DEVELOPMENT AND APPLICATION OF THE KIRIE WASTEWATER TREATMENT PLANT MODEL

Show moreThe Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) is tasked with protecting the public’s water supply and improving the quality of water in their service area’s watercourses. Principal in this mission are the seven wastewater treatment plants that are operated by MWRDGC. The greater Chicago area possesses a combined sewer system (CSS) that combines sanitary sewage and stormwater runoff. Because of this CSS, water reclamation plants are burdened with not only processing sewage and sanitary waste, but also stormwater runoff. As a result there can be a large variation in water quality and quantity. MWRDGC’s newest water reclamation plant is the James C. Kirie Water Reclamation Plant, which was completed in 1980. This plant operates as a nitrification plant with no separate distinct denitrification process. It is important to note that no clearly defined unit processes such as nitrification towers are utilized at the Kirie Water Reclamation Plant. Nitrification occurs primarily in the aeration basins and is currently sufficient to meet water quality standards. However, because of the current regulatory climate, stricter standards on effluent discharge are likely in the near future especially with respect to nutrients. Stricter standards on total nitrogen in effluent instead of the current ammonia limits are one such expected water quality change. As a result of this expectation, modeling modifications and processes at a treatment plant can be a key tool in adjusting to evolving standards. Because water reclamation plants vary greatly depending on their technology, influent and processes, computer modeling provides a convenient way to assess how the plant will react to dynamic changes in influent quality and still be able to meet static effluent standards. Although computer modeling has been applied to water reclamation plants for some time now, there are no clearly defined or accepted protocols for this modeling. Combined with the variation exhibited by various types of water reclamation plants, often modeling protocols must be custom created for individual plants or types of plants. What follows is a study and simulation of the Kirie Water Reclamation Plant. Simulation was used to examine wet weather events at the Kirie Water Reclamation Plant. Wet weather phenomena were explored in step-wise manner to determine the relative effects of different perturbations in influent water quality and quantity. The results show the various effects in effluent quality depending upon the variable or combination of variables deviated. Deviations in temperature and flow dominate all other variations simulated and result in the largest effect on effluent water quality. Deviations of 50% to both temperature and flow simultaneously yielded an increase in effluent BOD and NH3 at twice and six times the steady state values, respectively.

Show moreThe IPRO goal was to design a process for the production of the biotherapeutic compound IFN-Alpha from Chinese Hamster ovaries. After the process design was complete, a process flow diagram showing the actual process and separation steps was created and finally an economic analysis of the market feasibility of the product was prepared. The approach to the IPRO involved dividing the objectives into three major groups: (1) the Che 496 group was involved in the process design and the separation processes; (2) the Che 296 group was involved in the public perception of biotechnology, the useful products from biotechnology and the survey of the commercial biotherapeutic compounds; and (3) the 435 group was involved with the history of biotherapeutics, classification and actions infernos and the companies involved in the production of therapeutics. The individual members of these groups are seen on the team list below.

Show moreSudden Cardiac Arrest is a leading cause of death in the United States, accounting for an estimated 325,000 deaths each year according to the Heart Rhythm Foundation. Cardiac arrest is different from a typical heart attack because it involves a complete stopping of the heart. Brain injury is likely to occur if the cardiac arrest is untreated for more than 5 minutes and a person cannot be revived after 10 minutes of no action. This is because the arrest sets off a chain of metabolic reactions, which leads to swelling of the brain tissue. Cardiac arrest results in ischemia reperfusion injury, which is when circulation is restored and high levels of oxygen rich blood rushes back into the brain causing brain damage. Decreasing the metabolism of the victim may result in a decrease of ischemia reperfusion injury. Reducing the oxygen level that enters the body when the victim revives and slowly increasing this level may also reduce reperfusion injury. However, current procedures dictate that 100% oxygen be given to cardiac arrest victim.

Show moreThe goal of this project was to determine the feasibility of using the heated waste water from the Braidwood Generating Station for use in greenhouse applications. Though extremely efficient, the Braidwood Generating Station, like all nuclear power plants, still wastes two-thirds of all energy generated and pumps 1.5 million gallons per minute of warm waste water into its cooling lake. All of this thermal energy pumped into the cooling lake is wasted. IPRO 342 was looking to change that.

Show moreIPRO 344 investigated methods for safe, low-cost community gardening in the urban setting. Most community gardens within large cities are sited in vacant lots that have been previously built upon. When the structures that once occupied these sites were demolished, the debris filled the basements of the structures, and was then covered by a shallow layer of nutrient poor dirt. The resulting vacant lots pose two problems for community gardening. First, the ground becomes tough and nearly impossible to manually prepare for gardening purposes. Second, the presence of lead and mercury from the paint and other construction materials has been incorporated into the soil, which can be harmful when transferred into plants which are then ingested. Since most community gardens in low-income neighborhoods do provide food, it became the aim of IPRO 344 to inexpensively grow plants which would be safe to eat in an urban community garden.

Show moreIn an age where sustainability and “going green” have reached an all time high in both the media, and in politics, new initiatives are being explored more than ever before. Many of these initiatives would require drastic changes both in the way corporations do business, and in the way average citizens live their lives. However, there are initiatives which require very little change in lifestyle and business practice, and potentially represent great savings to those who choose to implement them. Like its predecessors, IPRO 346 aims to raise public awareness of the recycling and reuse of condensate produced by air-conditioning systems. This condensate is a byproduct of all AC units, and is currently sent straight to the sewer. Studies conducted by previous IPROs have not only indicated great potential for this initiative, but have also shown a great deal of public interest. Unfortunately, they have also revealed government policies and city codes which greatly restrict the use of this abundant resource. The aim of IPRO 346 is to work towards a change in these policies through the demonstration of a viable system. Members of the team equipped with a model of the systems we propose will meet with public officials, and others interested in the system, demonstrating its potential in hopes of getting policies in place which would allow such a system to be implemented. The IPRO has two main objectives: the development of a prototype and model for demonstration, and the marketing of the idea through the use of both social networks, and presentations to anyone interested. It is the aim of this team, that the accomplishment of these goals will result in both public demand for AC condensate recycling systems, and public policies which allow their use.

Show moreNeuronal populations in the brain achieve levels of synchronous electrophysiological activity during both normal brain function and pathological states such as epileptic seizures. Understanding how the dynamics of neuronal oscillators in the brain evolve from normal to diseased states is a critical component towards decoding such complex behaviors. In my studies, I assessed multi-site dynamics underlying seizure evolution in limbic epilepsy by analyzing oscillators in recordings of local field potentials from three brain structures (bilateral hippocampi and anteromedial thalamus) in a rat model of temporal lobe epilepsy extracted using the empirical mode decomposition (EMD) technique. The analysis revealed patterns of multi-site phase coherence during initiation and termination phases of seizures. The multi-site synchrony events as seizures naturally terminated were used to model electrical deep brain stimulation (DBS) protocols aimed at stopping ongoing epileptic seizures. The location and frequency of the natural termination synchrony varied between subjects but was stable in time within each animal. My studies reveal that DBS protocols were significantly more effective at rapidly stopping seizures when the frequency and location of multi-site stimulation reflected the endogenous synchrony dynamics observed in each subject. These results strongly suggest that tailoring DBS protocols to individual endogenous rhythms that may represent how brains naturally resolve epileptic seizures could play a critical role in vastly improving the overall efficacy of this important therapy.

Show moreSystem-On-Chip (SOC) is one of the most popular Computer Aided Design (CAD) methodologies in electronic system design. In this research, SOC design is investigated in two different types of applications: i) low cost and power efficient applications; and ii) high performance computing applications. To explore low cost and power efficient design, a microcontroller based wireless medical system is investigated. Two wireless communication protocols for medical applications and patient monitoring are analyzed. In addition, the ZigBee stack developed by TI and a medical amplifier are discussed. For high performance SOC applications, implementations of several matrix operations are examined. An improved fixed-point hardware design of QR decomposition is introduced and optimized for Xilinx FPGAs. A Givens Rotation algorithm is implemented using a folded systolic array and the CORDIC algorithm. This approach is highly suitable for high-speed FPGAs or ASIC designs. It is found that the Xilinx XC5VLX110T FPGA is capable of running the QR decomposition at 246MHz.

Show moreIn this project, the utilization of virtualized reality environments to the guidance of blind or visually-impaired people will be explored. A virtualized reality environment will be constructed based on visual sensory information and described verbally to the user instead of presented to him graphically. One of two contexts will be selected: a static scenario in which the motorized sensors and the system are located in the environment; or a mobile scenario in which a wearable computing system is worn by the user. The technical side of the project requires students with programming skills capable and/or interested in: image analysis, computer graphics, artificial intelligence, and hardware interface and design. The non-technical side of the project requires students capable and/or interested in: analyzing the guidance needs of blind and visually-impaired people, analyzing and experimenting with different verbal descriptions of visual scenes, assessing the level of detail with which the user is comfortable, and experimenting with and assessing the effectiveness of different descriptive schemes. In the long term, the insight and ideas developed in this project may lead to their further development, testing and implementation in practical applications for those who are blind and visually-impaired or more generally for people to communicate and collaborate with each other more effectively in a virtual fashion.
