Conceptual Designand Analysis Environment (CDAE). This unique design environment is specifically targeted at conceptualdesign of high-precision machinery and production equipment. The softwareis be to be programmed in Java using DirectX or OpenGL code to enhancethe 3-D graphics. An underlying database holds key information on a widevariety of structural and mechanical elements. The graphical interfaceuses geometric primitives for fast modeling and the underlying finiteelement code accurately predicts static and dynamic performance while keeping track of all aspects of economics (componentcost, lead time, reliability, maintenance requirements, etc). Design of microand meso machinery. Machining of even the smallest mechanical components is presently doneon conventional, ultra-precise production equipment. Because the workvolume of such machines is much larger than what is needed for these smallparts, machine utilization is generally very poor. The enormous weightof the machine tools results in reduced dynamic performance while thelarge overall size results make is susceptible to thermal errors and distortion.In addition, the big machines take up unnecessary floor space and havea fairly high price tag. The solution to the above mentioned dilemma would be the creation of productionequipment specifically designed for the machining of very small parts.The greatly reduced work volume would lead to drastically reduced overallsize, resulting in vastly improved dynamics and thermal performance. One graduate student is currently working on such a machine. We are designinga 5-axis micro-milling machine where the smallest endmill has a diameterof only 0.1mm (0.005”).

Design and fabricationof a device to support the head of cardiovascular surgeon. The surgeonis in India but I am in contact with his brother who is in the MPH programat UU. The device must attach (comfortably) to the surgeon and supportthe weight of his head while his torso is flexed when he performs surgery. It must be designed to be sterilized for use on the operating room. Design and fabricationof a device that can be attached to stairs which allows the user to havea "handle" in front of him/her when going up or down stairs.The handle must move with the user but allow the user to pull (when goingup) or push against (when going down), The handle must be unobtrusivewhen not in use and, if possible, attach to existing stairway handrails. Improvement ofan existing arm/hand support/restraint device to minimize erratic typingmovements for people with CP or other condition that cause spastic movements.The existing device is an open-loop system that simply resists arm movement.A closed-loop system is required which will respond to and dampen movementsas a function of (1) velocity, (2) acceleration, (3) jerk, or some combinationof these parameters. Current posturalcontrol literature suggests that very light sensory input on the hand(much below the ability to provide mechanical support) is very beneficialfor maintenance of balance. We would like to get a cane instrumented witha strain gauge (output +/- 10V) that I could connect to an A to D boardand gather info in conjunction with kinematic and kinetic data. The canewould probably have to be mounted on a base so that it could stand upon its own. Design and fabricationof a "mechanical horse" (like the mechanical Bulls you see inbars and at the state fair) to provide exercise for children with CP.

Flux Richardson Probe Development UTES - Urban Wind Measurements (NSF) TPAWT Virtual Wind Tunnel (NSF) Turbulence ina Stratified Wind Tunnel: An important aspect of environmental fluid mechanicsis the effect of stable stratification on turbulence. Applications arelargely in the areas of oceanic and atmospheric sciences (i.e., pollution“inversions” in the Salt Lake Valley). An undergraduate studentwill learn to measure mean and turbulent quantities using Particle ImageVelocimetry in the PFD’s thermally stratified wind tunnel. This project will begin during the spring semester 2002. Evening Transitionof the Atmospheric Boundary Layer in the Desert: A poorly understood periodof the diurnal cycle of the atmospheric boundary layer is evening transition.During this period of time energy supplied by the sun to the earth’ssurface decreases until thermal convection ceases. This is followed bya radiative cooling process by which a stable thermal stratification developsinto the night. Applications include air quality. Undergraduates willbe needed to obtain vertical profiles of atmospheric data using a tetheredmeteorological balloon. At least one student will be needed for to startwork in the spring semester 2002. (See http://www.mech.utah.edu/~pardyjak/) Evaluation ofQWIC-URB: QWIC-URB is a fast response computational model designed togenerate high resolution, 3 dimensional wind fields around buildings.For these geometries, the code produces complex 3D velocity fields resemblingaveraged experimental results. This model has been funded by the DOE tobe developed as an anti-terrorism tool (chemical/biological terrorism).An undergraduate student will compare numerical results with experimentalresults as well as perform a computational sensitivity analysis. Thisproject starts spring semester 2002.
