: 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

: Sustainability Planning of IIT Buildings (semester?), IPRO 320; The objective of IPRO 320, Sustainability Planning of IIT Buildings, is to contribute to the problem solving necessary to implement energy efficiency improvements in existing buildings and to the central steam and electric systems. Alternate possibilities for energy use in context with their building type and surroundings will be discovered through research of other university buildings at the University of Chicago, Loyola University, and IIT. This research will then be used in finding alternate forms of energy generation to secure the sustainability of the IIT campus., Deliverables for IPRO 320: Sustainability Planning of IIT Buildings for the Fall 2006 semester

: 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. Burgess-Norton Manufacturing Company is the world’s largest manufacturer of piston pins, as well as the leading producer of powder metal parts. Supplying many major car companies across the world, Burgess-Norton thrives on maintaining a high standard of quality in both their products and services. Recently there has been a change in the automobile industry that has affected the way piston pins are manufactured. These changes have brought on difficulties for the company as they must now change their product specs and adapt to the evolving market. Their main problem is the existence of nicks on the piston pins. The main goal of this IPRO team is to find a way to eliminate these nicks that occur throughout the company’s manufacturing process. This document will outline the main objectives and tasks that the team has been assigned with. Team structures, time lines and other plans are included. Also, a further company history and description of Burgess-Norton will be provided in order to make the objectives more clear., Sponsorship: Burgess-Norton Manufacturing Company, Deliverables

: 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

: Design Project for Production of IFN-alpha (semester?), IPRO 345; The 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., Deliverables for IPRO 345: Design Project for Production of IFN-alpha for the Spring 2006 semester

: Information Design for Plant Management to Predict Equipment Failure (semester?), IPRO 303; The present IPRO is a continuing research based on the findings of the previous semester during which they concluded that planned maintenances in a coal fired plant are carried out by ‘Engineering Specialists’ and the ‘Operations Manager” whereas unplanned outages are taken care of by the ‘Shift Supervisor’ . These findings lead us to our primary goals, namely: • To conduct a “Day-in-the-Life” study for both the two categories of personnel described above by direct solicitation of information from plant personnel. • Develop methods to gather this information such as surveys and/or interviews. • Compile the gathered data into a comprehensive report which should benefit the sponsor in better understanding their potential users., Deliverables for IPRO 303: Information Design for Plant Management to Predict Equipment Failure for the Fall 2007 semester
