Currently, advanced tools for modeling injection modeling of thermoplastics and predicting formed part dimensional stability and residual stress content use the static bulk modulus of the polymer at the temperatures and pressures associated with the molding process. The short cycle times associated with injection molding, however, could be more accurately modeled if dynamic bulk modulus data were ...

The goal of this project is to develop an demonstrate the feasibility of computer-based, multimedia instruction to facilitate the acquisition of difficult to learn mathematics principles. The goal will be accomplished through the design and development of a multimedia interface that uses audio prompts, interaction graphics, and text displays to guide learners through problem solving activities. ...

Reuse in software engineering is an exciting concept that has yet to be reliably implemented. The number of program subroutines that are truly generic (and therefore applicable across all applications) is limited. However, there are specific applications that are required by many organizations, albeit with a set of constraints specific to each organization. This project proposes to design a too ...

We propose to develop DIALOG, an environment for collaborative decision making that will enable health care providers and administrators to model, learn, and reason about their business enterprise. DIALOG will utilize a user-friendly, pen- and gesture-based graphical interface, and will enable "any time/any place" collaboration over shared digital libraries and dynamic "microworld" simulations. ...

It is proposed to develop a miniature guarded hot plate apparatus that can be used to determine the thermal conductivity or thermal resistance of very small specimens (1 to 3 cm square) of thermal insulation materials over a temperature range from at least -40 degrees Celsius to +65 degrees Celsius, with the apparatus having the capability to carry out measurements under controlled environments of ...

A combustion environment can be described by a characteristic fuel-to-air ratio normalized by the stoichiometric fuel-to-air ratio, otherwise defined as an equivalence ratio, _. The equivalence ratio is used extensively in a wide range of combustion fields from fundamental flame studies, to full-scale fire testing, to power plant operations. There have been basically two methods for calculating ...

The proposed research is intended to be a major step in the development of a modelocked diode laser system, capable of replacing several expensive and complex components used in seeding of OPO, OPA, and OPG, with direct applications in non-linear optical diagnostics. The company has successfully demonstrated a modelocked diode laser system which features hybird modelocking and produces 100 picojo ...

The optical pumping of helium at 1083 nm is proving useful in applications involving magnetometry, polarized electron sources and neutron spin filters, but existing sources at 1083 nm are limited in efficiency, lifetime, reliability, compactness and power. The crystal laser material Nd:LuAlO3 (neodymium doped lutetium orthoaluminate) has ideal spectroscopic properties, but previous growths have d ...

This proposal will emphasize outfitting a virtual classroom and creating a skills (CNC) oriented training program. The virtual classroom will involve contextual learning using a realistic simulation of the manufacturing environment. The simulation will have all of the characteristics of a machine shop, but will allow the learner to explore and experiment ("discover") in ways that would not be pr ...
