Design of a statewide system for health education.

Eight explicitly identified assumptions about the nature of the health care delivery problem were used to design a statewide health education system based in a university medical center. The system design and how it is being implemented in one state (West Virginia) are discussed. Three unexpected outcomes regarding coordination of agency services, the political attractiveness of the system, and the system as a resource to new health education programs are briefly discussed. Two prerequisites for system development and the importance of the assumptions in a system's design are identified. (16 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Preliminary Design System for Concrete Box Girder Bridges

A neural network-based design system is presented in this paper for preliminary design of concrete box girder bridges. The system is based on a loose coupling model that integrates the artificial neural network and the fuzzy network to perform the task of noisy data filtering, knowledge extraction, and candidate synthesis. After a comparative study, the radial basis function neural network is chosen in the design knowledge generation instead of the commonly used back-propagation neural network. The fuzzy network is employed to determine the integer types of design parameters. The developed system provides a few feasible design configurations, and enables the user to overwrite some of the design parameters, so that that user can have a wide choice in his preliminary design. The accuracy of the neural network testing and the influence of the size of the design cases on the neural network prediction are discussed. A design example is included to illustrate the design procedure.

Axial and Shear Behavior of Glass Fiber Reinforced Gypsum Wall Panels: Tests

Glass fiber reinforced gypsum (GFRG) walls and their associated building system are the new building product and building system that have been developed in the Australian building industry in the last decade. GFRG walls are factory made glass-fiber reinforced gypsum hollow walling panels with/without in situ reinforced concrete filling inside the cavities. GFRG can be used as various structural elements, such as walls and slabs. GFRG, in its short life, without extensive product development and comprehensive structural design guidelines, has been used as the principal wall construction material in more than 3,000 dwellings across Australia. As GFRG walls find more and more applications and interests in the building industry in Australia as well as in other countries, comprehensive structural design guidelines for GFRG walls and their building system have become necessary. Comprehensive experimental testing and theoretical studies started in 2002 as an international research and development program to develop structural design guidelines for GFRG walls. The axial and shear tests are reported in this paper.     

Fluid flow in casting rigging systems: Modeling, validation, and optimal design

In this work, a methodology for the optimal design of flow in foundry casting rigging systems is discussed. The methodology is based on a novel, fully analytical design sensitivity formulation for transient, turbulent, free-surface flows. The filling stage of the casting process is modeled by solving the time-averaged form of the Navier-Stokes equations via a turbulent mixing-length model, in conjunction with the volume-of-fluid (VOF) method for modeling the free surface. The design of the runner and gating system of a simple block casting is presented as an example application for using sensitivity information in design. The analytical sensitivity routine is coupled to a numerical optimizer to yield an automated method for optimal design of the casting rigging system. The finite element model of the filling process is verified through physical experimentation. Solutions of glycerol and water are used to perform laminar and turbulent flow filling experiments, which are used to verify independently the VOF algorithm and the adequacy of the mixing-length model. The results show that the numerical model accurately reproduces the main features of the flow, and filling times agree with acceptable accuracy. Finally, the analytical techniques are used to obtain an optimal runner shape, which eliminates air entrainment, and the design is verified experimentally.
