Analysis for the Seismic Response of Liquid Containers
An analytical model is presented for the nonlinear response of fluid containers whose bottom may separate from and lift off their foundation, during base excitation. First, the hydrodynamic...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Computer Aided Design of Monolithic Integrated Circuits
An algorithm has been developed to relocate the sites of electrical components and integrated circuits. The process simulates site location changes in order that path lengths of conductors...
Planning and Implementation of a Heterogeneous Tri-Campus Computer Network
In 1988, Fairleigh Dickinson University received a grant from the New Jersey Department of Higher Education for the establishment of a Tri-Campus Computer Network to link all it's...
Potential Flow Over a Wavy Bed: A Persistent Error
The standard small-amplitude theory of potential flow over a wavy bed is briefly discussed, together with the three special values of the Froude Number which define four different flow...
Derivation of a Stability Principle from the Shields Criterion
The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...
A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...
Using Sediment-Threshold Theories in Waves and Currents
Fundamentally different threshold-of-motion theories were applied to sand transport in two different coastal environments. Several recommendations for threshold application were reached....
A Continuum Mechanics Approach to Loose-Bed Motion
A mathematical model is presented for simulation of loose-bed motion. The physical system is separated into two regions, a bottom region and an upper region. The bottom region is representative...
Critical Shear Stress of Armour Coat
The problem of the determination of the critical shear stress of the armour coat is important in sediment transport, river degradation and aggradation and flow discharge regulation. The...
Convolution-Integral Modeling of Non-Equilibrium Sediment Transport
In transient process of sediment transport due to unsteady or/and nonuniform flow or discontinuity of boundary condition, non-equilibrium process appears and it sometimes plays an important...
Cellular Automaton Simulation of Viscous Free Surface Fluid Dynamics
It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating...
A Design Parameter Study of Turbine Draft Tube by Viscous Flow Analysis
Viscous flow analysis based on the full Reynolds-averaged Navier-Stokes equations is being applied to predict successfully turbulent flow characteristics and energy losses in different...
Issues in Computer Based Design/Construction Integration
Design and construction processes are widely regarded as too splintered for industry effectiveness. By improving communication and process integration, reduced costs and improved facilities...
AEC Experience with Expert Systems in Construction
The application of expert systems in the construction industry requires the use of general-purpose computers, such as microcomputers, minicomputers, and mainframes. The use of commercial...
Integrating Voice Recognition Systems with the Collection of Project Control Data
The Construction Industry in the 1990's will be dominated by emphasis on Productivity, Competitiveness and Innovation. Success or failure in these areas lies in one word, Technology, and...
Turbine Casing and Distributor Hydraulic Design
Interactive casing and distributor hydraulic design and flow analysis software has been developed and tested. Until now, its application is limited to radial distributor turbo-machines....
An Integrated Site Controller-Network Monitoring System for Small Scale Hydroelectric Sites
Over the past decade more and more small scale hydroelectric power developers have faced the question of the economic feasibility of installing microprocessor based control systems for...
Moments of Nonlinear Systems
In this paper the problem of writing the equations of moments of nonlinear systems excited by both external and parametric Gaussian white processes is re-examined. The classical K. Ito...
Stochastic Bifurcation of Nonlinear Parametric Systems
Parametrically excited systems with progressive restorings possess two different solutions: the trivial one and a stationary branching process. The second solution is physically existent...
