Predicting THM Formation with Artificial Neural Networks
An existing mathematical model to predict trihalomethane formation and speciation was enhanced through the use of artificial neural network technology. The model corresponded well with...

Zonification of Areas with Inundation Risk by Means of Mathematical Modeling in the Rosario Region, Argentina
Water course flood valleys are often being subjected to processes of urbanization that take place in several big cities of the world. Therefore, urban planning strategies based on hydric...

A Combined Physical and Mathematical Modeling Scheme for Kapichira Hydropower Project, Malawi
A physical model and a mathematical model were used to study the flow patterns in a reservoir having a complicated bathymetry. The physical model measurements were compared with the predictions...

Near Field Modeling
Results of near field modeling of the wastefield formed by the Sand Island, Honolulu, ocean sewage outfall are presented. Over 20,000 simulations were run with the mathematical model RSB...

Air-Supported Roof Redux
Long-span, low profile, air-supported roofs have been dramatic additions to a dozen public arenas built in the 1970s and early 1980s. The advantages of these roofs were overshadowed by...

A Safer Earthquake Design Code After NorthRidge
Three recent killer California earthquakes have demonstrated serious deficiencies in our current building codes. As they do after all such events, officials in California and other states...

Thermal Response in Antenna Under Laser Irradiation
This investigation focuses on the thermal response of two objects under medium-intensity continuous-wave (CW) laser irradiation: (1) a homogeneous slab and (2) a complex electronic component,...

Inelastic Response of Metal Matrix Composite Tubes
An analytical method which exactly satisfies the equations of the boundary value problem for the inelastic response of laminated metal matrix composite tubes on a point-wise basis is presented....

Thermal Cycling of Thin and Thick Ply Composites
An experimental study was conducted to determine the effects of ply thickness in composite laminates on thermally induced cracking and changes in the coefficient of thermal expansion (CTE)....

Convergence Rates of the Method of Successive Elastic Solutions in Thermoplastic Problems of a Layered Concentric Cylinder
This paper examines convergence rates of the method of successive elastic solutions, proposed by Mendelson, in determining the thermoplastic response of an arbitrarily layered concentric...

Optical Scatter From a Space Craft Mirror Due to Microscopic Impacts
This article addresses the issue of how micrometeoroid and man made debris in the space environment can adversely change the optical resolution of a mirror. The study used an algorithm...

Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...

Modeling of Interaction of Small Particulates in Earth Orbit
The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...

Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...

Efficient Path Planning Strategies for Unmanned Rover Vehicles
Path planning strategies are studied using an optimization model. Four main sub-models are discussed that contribute to the computing of minimum energy vehicle path planning. These are:...

Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...

Modelling of Extended Endplate Bolted Connections
A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

Combinatary Net-Shell Roofs of Elliptic Paraboloid of Zhaoqing Gymnasium
Zhaoqing Gymnasium is a multi-functional sports building, whose structural modelling takes Zhaoqing City Flower(Lotus) as the main theme; adopts a combinatory ellipic paraboloid net-shell...
