: Cure for the IKIA Syndrome : presented at IACRL 2008 conference: List of failures; Informal observations of a practical and creative approach piloting Blended Library Instruction for undergraduate Civil Architecture and Engineering students, in collaboration with faculty. At Illinois Institute of Technology students don’t receive library instruction as a required class or in tandem with a composition class. Faculty will schedule one-time sessions, which ideally should be planned with a class assignment in mind, but students are rarely engaged with a one time instruction. Many have IKIA syndrome or I Know It Already syndrome. The Millennials are a group that has integrated technology into every aspect of their lives and they assume that retrieving useful or necessary information will be easy. When they discover this isn’t the case lack of time, heightened anxiety, and increased frustration can prevent them from doing their best work. By intentionally creating a similar crisis prior to library instruction, students were more interested in what they stood to gain during pending library instruction. In this presentation we will discuss: 1) A creative means of delivering library instruction to a traditionally challenging population: engineering undergraduate students 2) Qualitative information collected via multiple assignments and interpreted in a quantitative fashion, as well as our observations. 3) A method for preparing students for library instruction that can be applied in almost any discipline without asking the instructor to sacrifice class time.

: Statistical monitoring of multivariable dynamic processes with state-space models; Industrial continuous processes may have a large number of process variables and are usually operated for extended periods at fixed operating points under closed-loop control, yielding process measurements that are autocorrelated, cross-correlated and collinear. A statistical process monitoring (SPM) method based on multivariate statistics and system theory is introduced to monitor the variability of such processes. The statistical model that describes the in-control variability is based on a canonical-variate (CV) stare-space model that is an equivalent representation of a vector autoregressive moving-average rime-series model. The CV state variables obtained from the state-space model are linear combinations of the past process measurements that explain the variability of the future measurements the most. Because of this distinctive feature, the CV state variables are regarded as the principal dynamic directions A T-2 statistic based on the CV state variables is used for developing an SPM procedure. Simple examples based on simulated data and an experimental application based on a high-temperature short-time milk pasteurization process illustrate advantages of the proposed SPM method.

: Enhancing the Reliability and Performance of Paper Shredders (Semester Unknown) IPRO 321; Spring semester 2007, the Manhattan Group came to IIT seeking advice regarding the improvement of their paper shredder. The paper shredders are manufactured in China and sold across the world, including the United States, under the Royal brand name. Each year, over a million paper shredders are sold. Consumers want paper shredders that are quiet and long lasting and are available at the lowest possible price. The Manhattan Group has asked us once again, the students of IPRO 321 and Professor Maurer, for the fourth straight semester to seek potential methods and problems in their shredder. These include improving the sound reduction, the gear optimization, and other features. The MMAE lab and machine lab will be used extensively for gear, sound, and material testing and design. Software resources, sound measuring equipment, and EE equipment will be used as well. Potential legal and/or ethical issues will involve patents and idea ownership. Since this a sponsored IPRO, all discoveries will be property of Mr. Seth Lewis and the Manhattan Group. This potentially could be an issue where this IPRO will be unable to provide necessary information to the IPRO office regarding work and progress due to ethics., Deliverables

: Cessation of Screech in Underexpanded Jets; In significantly underexpanded jets, screech inherently ceases to exist. This paper studies screech cessation in a supersonic rectangular jet and provides an explanation for its occurrence. Experimental data are presented for fully expanded Mach numbers, M-j, ranging from 1.1 to 1.9. Screech becomes unsteady beyond M-j = 1.65 and ceases to exist beyond M-j = 1.75. The reason for this cessation has remained a mystery, and this paper examines three suspects: (i) the theory of a frequency mismatch between screech tones and the band of the most-amplified jet instability waves, (ii) the notion that Mach disk formation disrupts the shock-cell structure and weakens the screech-producing shocks, and (iii) the idea that acoustic feedback and receptivity diminish at high levels of underexpansion. A thorough interrogation of experimental data shows that (i) is not the main cause of screech cessation here, (ii) plays an insignificant role, and (iii) appears to have been largely responsible for screech cessation. Cessation occurs because feedback to the jet lip is diminished due to excessive expansion of the jet boundary. Further, since the jet lip now reflects and scatters low intensity sound, the end result is poor receptivity at the initial shear layer. This theory is substantiated by the re-activation of screech when the nozzle lip thickness is made larger than the expanded jet boundary. Finally, increasing lip thickness is seen to produce a systematic shift (to higher M-j) of the onset of cessation. The results of this study are of direct relevance to the sonic fatigue problem in aircraft structures, because understanding screech helps prevent such damage.

: Video Disc Transducer System and Method; A video disc record having a spiral video record track which can provide reproduced video signals with a desired frame rate such as thirty frames per second while the disc record is rotated at a very low speed such as two revolutions per minute. A preferred transducer machine uses a pulsed light source to supply successive light images to a video camera readout. Control signals are recorded on helical control tracks so that reproduction thereof facilitates the generation of a desired standard video signal from the video camera., Sponsorship: IIT Research Institute, United States Patent

: Self-Regulating Class E Resonant Power Converter Maintaining Operation in a Minimal Loss Region; A self-regulating Class E/resonant power converter includes a power switching device which is gated on at each transition between negative and positive half cycles of the load current by drive signals generated by a drive circuit, the rate at which the drive signals are generated being controlled by a zero crossing detector which monitors the load current and adjusts the frequency of the drive signals in correspondence with changes in the time between successive negative-to-positive zero crossings of the load current such that the power switching device continues to be switched on at substantially zero voltage, zero slope conditions to maintain the power converter operating at the optimal Class E frequency., Sponsorship: Illinois Institute of Technology, United States Patent

: Piston and Piston Pin Manufacturing Process Improvement (Semester Unknown) IPRO 339; The team of IPRO 339’s main objective is to assist Burgess-Norton Manufacturing Company with eliminating a persisting problem that has been affecting the company for many years.

: Emotional reactions to variations in contract language; This article introduces a theory of emotion-driven behavior in construction contracting and provides support for this theory by presenting the quantitative results of a study on the emotional reaction of individuals to the language in contract clauses. Four different versions of the standard Delay Clause found in most construction contracts were extracted from four different contracts and were presented to a group of 27 individuals. Participants rank ordered the clause versions from 1 (most negative) to 4 (most positive). Overall, Clause Version 2 was ranked as having the most negative contract language, with nearly 75% of the participants ranking it as most negative. In contrast, Clause Version 4 was ranked as having the most positive contract language, with over 50% of the participants ranking it as most positive. Participants likewise selected negative emotion words to describe their reaction to Clause Version 2 and positive emotion words to describe their reaction to Clause Version 4. The findings suggest that contract clauses that contain negative language do tend to generate negative emotional reactions while positive contract language do tend to generate positive emotional reactions.

: HACCP with multivariate process monitoring and fault diagnosis techniques: application to a food pasteurization process; Multivariate statistical process monitoring (SPM), and fault detection and diagnosis (FDD) methods are developed to monitor the critical control points (CCPs) in a continuous food pasteurization process. Multivariate SPM techniques effectively use information from all process variables to detect abnormal process behavior. Fault diagnosis techniques isolate the source cause of the deviation in process variable(s). The methods developed are illustrated by implementing them to monitor the critical control points and diagnose causes of abnormal operation of a high temperature short time (HTST) pasteurization pilot plant. The detection power of multivariate SPM and FDD techniques over univariate SPM techniques is shown and their integrated use to ensure the product safety and quality in food processes is demonstrated., Endnote format citation for DOI:10.1016/j.foodcont.2004.04.008
