- Empirical modeling of systems with output multiplicities by multivariate additive NARX models
- Multivariable additive NARX (nonlinear autoregressive with exogenous inputs) modeling of process systems is presented. The model structure is similar to that of a generalized additive model (GAM) and is estimated with a nonlinear canonical variate analysis (CVA) algorithm called CANALS. The system is modeled by partitioning the data into two groups of variables. The first is a collection of future outputs, and the second is a collection of past input and outputs and future inputs. This approach is similar to linear subspace state-space modeling. An illustrative example of modeling is presented on the basis of a simulated continuous chemical reactor that exhibits multiple steady states in the outputs for a fixed level of the input., Endnote format citation for DOI:10.1021/ie9906464

- Development of High Bandwidth Powered Resonance Tube Actuators with Feedback Control
- A high bandwidth powered resonance tube (PRT) actuator potentially useful for noise and flow control applications was developed. High bandwidth allows use of the same actuator at various locations on an aircraft and over a range of flight speeds. The actuator selected for bandwidth enhancement was the PRT actuator, which is an adaptation of the Hartmann whistle. The device is capable of producing high-frequency and high-amplitude pressure and velocity perturbations for active flow control applications. Our detailed experiments aimed at understanding the PRT phenomenon are complemented by an improved analytical model and direct numerical simulations. We provide a detailed characterization of the unsteady pressures in the nearfield of the actuator using phase averaged pressure measurements. The measurements revealed that propagating fluctuations at 9 kHz were biased towards the upstream direction (relative to the supply jet). A complementary computational study validated by our experiments was useful in simulating the details in the region between the supply jet and the resonance tube where it was difficult to gather experimental data. High bandwidth was obtained by varying the depth of the resonance tube that determines the frequency produced by the device. Our actuator could produce frequencies ranging from 1600 to 15,000 Hz at amplitudes as high as 160 dB near the source. The frequency variation with depth is predicted well by the quarter wavelength formula for deep tubes but the formula becomes increasingly inaccurate as the tube depth is decreased. An improved analytical model was developed, in which the compliance and mass of the fluid in the integration slot is incorporated into the prediction of resonance frequencies of the system. Finally a feedback controller that varied both the resonance tube depth and spacing to converge on a desired frequency was developed and demonstrated. We are optimistic that numerous potential applications exist for such high bandwidth high dynamic range actuators.

- Solar Hydrogen Hybrid System (semester?), IPRO 301
- The photovoltaic/hydrogen hybrid energy system IPRO was started eight years ago. A group of students with their faculty advisor began a semester to investigate the use of solar energy to power an electric sign. Since that time, a significant amount of progress has been made. The project progressed from the design phase to the laboratory phase. Once functioning, it was transferred to the roof of the Co-Gen plant on the IIT main campus. During this phase of the project, Phase I, a photovoltaic system was set up that included several solar panels on the roof. Also, a large LED sign was installed on the roof. An array of power management devices were set up at the project site inside the Co-Gen plant. Phase II of the project was planned in order to incorporate an electrolyzer and fuel cell as an energy back up system in conjunction with the PV system. Although these components exist at the work site, they are not integrated into the complete system and are merely there to demonstrate using hydrogen to power an electric load., Deliverables for IPRO 301: Solar Hydrogen Hybrid System for the Fall 2004 semester

- Influence of the target on multiparticle production in the forward domain in p+Pb collisions at 158 GeV
- In this talk we show the influence of the target on multiparticle production in the forward hemisphere in p+Pb collisions at top SPS energy. The multiplicity distributions appear to be almost target independent in the projectile fragmentation domain and the effect of fluctuations of the number of target participants is not seen in the projectile fragmentation region. We compare the obtained results with those for p+p interactions and predictions of models., Sponsorship: IIT College of Science, High Energy Physics Division of Argonne National Laboratory

- J2EE Versus .NET (Fall 2003) IPRO 337
- Distributed computing has become quintessential in the business world for its ability to connect people with information and resources. Two available technologies that provide distributed computing are Microsoft’s .NET and Sun’s J2EE. The objective of this Interprofessional Project is threefold: 1) to study both technologies, 2) to develop and analyze a list of criteria that are important to Bank One and how they develop software, and 3) to rate each criteria, which will help Bank One make an informed technology choice between .NET and J2EE, when reengineering legacy systems. At a high level, there are significant differences between these technologies. The .NET environment offers a host of programming languages and an integrated development environment. However, applications developed in .NET are limited to running on a Microsoft Operating System. J2EE offers one language, Java, but a wide selection of development tools. Applications developed in J2EE may run on several different operating systems. Bank One will have both .NET and J2EE available for development and by using Web Services they will be able to have separate modules communicate with each other., Sponsorship: Bank One Corporation, Project Plan for IPRO 337: J2EE Versus .NET for Fall 2003 semester

- Scoping Health Care Informatics (Fall 2003) IPRO 372/472: Scoping Health Care Informatics IPRO372%3A472 Fall2003 Final Presentation
- Health care is a complex, highly constrained, high stakes environment that relies heavily on information. The field of medical informatics has evolved to create software solutions that are intended to support the organization, management and use of health care information. Medical informatics applications include patient care, teaching, research and health care administration from the patient record up through unit, departmental and hospital schedules and reports. Such products and systems typically seek to make the most of current technology. However, their implementation frequently shows little regard for the way people work. This IPRO will scope the field of medical informatics. This will call on team members to: (a) review reports, articles and products to describe the current state of the art; (b) pose crucial questions regarding met and unmet needs; and (c) reach conclusions regarding the future of health care and address the implications for how informatics needs to evolve. Information technology in health care spans all departments of the organization. Team members will need to grasp the complex relationships among all health care departments and disciplines. This will require an awareness of medical practice, law, business, human behavior, software and information systems. The project will be challenging for any IIT undergraduate or graduate student. Degree areas that are expected to have a particular interest in this project include computer science, psychology, design, and business., Sponsorship: IIT Collaboratory for Interprofessional Studies in collaboration with the Cognitive Technologies Laboratory, University of Chicago Hospitals, Project Plan for IPRO 372/472: Scoping Health Care Informatics for Fall 2003 semester

- Aeroacoustic Features of Coupled Twin Jets with Spanwise Oblique Shock-Cells
- This paper experimentally investigates the aeroacoustics of coupled twin jets of complex geometry. The study was motivated by the fact that twin jet configurations that are commonly used in aircraft propulsion systems can undergo unpredictable resonant coupling resulting in structural damage. Further, nozzles with spanwise oblique exits are increasingly being considered for their aerodynamic and acoustic advantages, as well as stealth benefits. Although several studies have examined aspects of twin jet coupling, very little data is available on the coupling of jets from nozzles of complex geometry. Our study focuses on twin convergent nozzles with an aspect ratio of 7 with spanwise oblique exits operated over the fully expanded Mach number range from 1.3 to 1.6. The inter-nozzle spacing (s/h) was varied from 7.4 to 13.5. However, the focus remained on the lower spacing that is more representative of aircraft applications. Several interesting results have emerged from this study: (1) Coupling of twin nozzles with a beveled exit was observed only when the beveled edges faced each other and the nozzles formed a 'V' shape in the inter-nozzle region. Specifically, if the two beveled edges were oriented away from each other to form an arrowhead (W) shape no coupling was observed. (2) Despite the presence of spanwise antisymmetric, spanwise symmetric and spanwise oblique modes for the single nozzles, only the first two modes were evident in the coupling. (3) The symmetric coupling produced unsteady pressures in the inter-nozzle region that were up to 7.5 dB higher than the antisymmetrically coupled case. (4) Dynamic tests conducted by moving the nozzles apart while they were operating or by continuously changing the stagnation pressure at fixed inter-nozzle spacing revealed that coupling modes could co-exist at non-harmonically related frequencies. These dynamic tests reproduced the static test data. (5) The frequency of both coupling modes agrees with the higher order waveguide modes based on Tam's theory. (6) Differences in broadband shock noise between the 'V' and 'A' configurations were also documented. Our results provide an understanding of complex twin jet coupling and will serve as benchmark data for validating computational models. (C) 2003 Elsevier Ltd.
