Technology, Values, and Ethics : A Framework
(Center for the Study of Ethics in the Professions, IIT, 1992-02-01)
Three words of my title--"technology", "values", and "ethics"--have this in common: they have all been used in enough different ways to be dangerous. To provide the framework my title promises, I shall have to distinguish ...
Controller performance assessment by frequency domain techniques
(ELSEVIER SCI LTD, 1997-06)
A system identification based method for assessing the performance of closed-loop systems is proposed, utilizing measures which coincide naturally with classical and modern frequency domain design specifications. Standard ...
Modeling, monitoring and control strategies for high temperature short time pasteurization systems - 1. Empirical model development
(ELSEVIER SCI LTD, 1998-02)
Dynamic models of high temperature short time (HTST) pasteurization systems can be developed by using empirical model development paradigms such as transfer functions and times series models. Properly designed experiments ...
FLIP-FLOP JET NOZZLE EXTENDED TO SUPERSONIC FLOWS
(AMER INST AERONAUT ASTRONAUT, 1993-06)
An experiment studying a fluidically oscillated rectangular jet flow was conducted. The Mach number was varied over a range from low subsonic to supersonic. Unsteady velocity and pressure measurements were made using hot ...
Automated control and monitoring of thermal processing using high temperature, short time pasteurization
(AMER DAIRY SCIENCE ASSOC, 1997-10)
High temperature, short time pasteurization was used to evaluate a computer-based system for controlling the pasteurization process, acquiring data, and monitoring records. Software was used for the control of hot water ...
MATHEMATICAL-MODELS OF COCURRENT SPRAY-DRYING
(AMER CHEMICAL SOC, 1995-10)
A steady state mathematical model for a cocurrent spray dryer-is developed. The model includes the mass, momentum, and energy balances for a single drying droplet as well as the total energy and mass balances of the drying ...
EVALUATION OF FLIP-FLOP JET NOZZLES FOR USE AS PRACTICAL EXCITATION DEVICES
(ASME-AMER SOC MECHANICAL ENG, 1994-09)
This paper describes the flowfield characteristics of the flip-flop jet nozzle and the potential for using this nozzle as a practical excitation device. It appears from the existing body of published information that there ...
High Speed Jet Flows, 1995: Presented at the 1995 ASME/JSME Fluids Engineering and Laser Anemometry Conference and Exhibition, August 13-18, 1995, Hilton Head, South Carolina
(American Society of Mechanical Engineers, 1995)
Screech Tones from Rectangular Jets with Spanwise Oblique Shock-cell Structures
(Cambridge Univ Press, 1997-01-10)
Understanding screech is especially important for the design of advanced aircraft because screech can cause sonic fatigue failure of aircraft structures. Although the connection between shock-cell spacing and screech ...
Coupling of Twin Rectangular Supersonic Jets
(Cambridge Univ Press, 1998-01-10)
Twin jet plumes on aircraft can couple, producing dynamic pressures significant enough to cause structural fatigue. For closely spaced jets with a moderate aspect ratio (e.g. 5), previous work has established that two ...
