10:30 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: The Design of Computer Experiments to Determine Optimum and Robust Control Variables
In this talk I will discuss the design of computer experiments when there are two types of inputs: control variables and noise variables. Control variables are determined by a product designer while noise variables are uncontrolled in the field but take on values according to some probability distribution. I will consider two problems. The first is the situation in which there are two outputs (responses), each of which is expensive or time consuming to compute. The objective is to find values of the control variables that optimize the mean (over the distribution of the noise variables) of one response subject to a constraint on the mean of the other response. The second is to find values of the control variables at which the response is insensitive to the value of the noise variables. For both problems, I will describe a sequential strategy to select the values of the inputs at which to observe the responses. The methodology is Bayesian; the prior takes the responses as draws from a Gaussian stochastic process. At each stage, the strategy determines which response to observe and at what set of inputs so as to maximize a posterior expected "improvement" over the current estimate of the optimum.

10:45 AM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR: Computational Modeling of the Rheological Properties of Suspensions: Recent Advances and Challenges
The flow properties of complex fluids like suspensions is of fundamental interest and plays an important roll in a wide variety of technological processes. Examples include the flow and placement of concrete, polymer colloidal systems and even the design of bulletproof vests. Predicting the rheological properties of suspensions remains a great challenge. In this talk I will describe a dissipative particle dynamics (DPD) based approach for modeling suspensions. The model recovers the dilute limit intrinsic viscosity prediction of Einstein and can account for second order effects like the Huggins coefficient. The rotation period of a single spheroid under shear is consistent the predictions of Jeffery. Studies of the flow of spheroids at higher volume fractions produce a nematic phase. At high solid fractions the usual DPD interactions are too weak to prevent overlap of the rigid bodies. To approximate hard sphere systems, at high solid fractions lubrication forces were added to the usual DPD algorithm. Results are compared with previous work using the Stokesian Dynamics method. Applications of DPD to study the rheological behavior of cement based materials will be discussed.

10:30 AM - NIST COLLOQUIUM SERIES: Computer-Integrated Surgery: Coupling Information to Action in the 21st Century
The impact of Computer-Integrated Surgery (CIS) on medicine in the next 20 years will be as great as that of Computer-Integrated Manufacturing on industrial production over the past 20 years. By extending the ability to plan and carry out surgical interventions, CIS systems will reduce costs, improve clinical outcomes, and improve the efficiency of health care delivery. We see the emergence of two complementary paradigms: surgical CAD/CAM systems that integrate patient-specific models and execution environments; and surgical assistant systems that work cooperatively with the surgeon. This presentation will illustrate these themes and outline current barriers and opportunities for future developments.

11/9/04 9:00 AM - ANALYTICAL CHEMISTRY DIVISION SEMINAR: ASTM International/NIST Workshop
ASTM International/NIST Workshop: "A Business Plan for Quality Results" Tuesday, November 9 from 9:00 a.m. to 5:30 p.m. and Wednesday, November 10 from 9:00 a.m. to 12:00 noon. ASTM International Committee E01 and the NIST Analytical Chemistry Division will hold a workshop to discuss the requirements of the US metals industry for Certified Reference Materials (CRMs). Special attention will be given to ISO 17025 General requirements for the competence of testing and calibration laboratories and its consequences for industry laboratories and developers of standard test methods who need CRMs to support their activities. Workshop speakers and attendees will look for opportunities to improve collaboration and communication among NIST, ASTM International, quality assessors, and commercial producers of reference materials. NIST staff are encouraged to participate.

12/2/04 1:30 PM - INFORMATION SERVICES DIVISION SEMINAR: Hassler Dedication
Ferdinand Rudolph Hassler (1770-1843) will be celebrated by NIST, NOAA, and the Hassler family in a ceremony that will take place in the Green Auditorium, Thursday, December 2, 2004, from 1:30 p.m to 3:00 p.m. Hassler, called the forefather of NIST, was the first Superintendent of the Department of Treasury’s Office of Weights and Measures (now NIST Metrology) and also the first Superintendent of the U.S. Coast Survey (now a part of NOAA). The ceremony commemorates the installation of the Hassler memorial stone in the NIST Administration Building lobby. The stone, which includes an engraved tribute to Hassler and portrait relief, was previously at the Hassler gravesite in Philadelphia where a new stone has been erected. Visit the NIST Museum for the Hassler display, and also the Virtual Museum for a Hassler exhibit: http://museum.nist.gov/exhibits/exit1/Room2.html
