A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Coastal Engineering Design Codes in the Netherlands
Dutch research strategy on water defences and the resulting coastal and hydraulic engineering design codes (technical documents) are briefly overviewed. Special attention is paid to organizational...
Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...
The Control of Large Amplitude Liquid Sloshing with Moving Baffles
Numerical simulations of three-dimensional viscous liquid sloshing in rectangular containers were carried out using an improved volume of fluid technique in conjunction with the Navier-Stokes...
Computerized Tomographic Analysis of Fluid Flow in Fractured Tuff
The purpose of this summary is to demonstrate the usefulness of X-ray computerized tomography to observe fluid flow down a fracture and rock matrix inhibition in a sample of Bandelier...
Joint Network Modeling and Scale Effects in Rock
Joint networks play a vital role in the mechanical and hydraulic behavior of rock masses. A realistic representation of joint geometry in rock masses and correct understanding of the mechanical...
Vortex Suppression in Wet-Pit Pump Intakes
Two distinct examples to suppress both air-entraining and boundary-attached subsurface vortices in large vertical pump intakes are presented that were developed by means of hydraulic model...
Slip Velocity and Temperature Jump in Flow over Rough Surface
The expressions for the slip velocity and the temperature jump are determined and used as the boundary conditions in the calculation of turbulent flow over rough surfaces. The slip velocity...
Shear Flow Between Walls in Relative Motion
The paper reports on experiments on Couette flow, i.e., the shear-induced flow between surfaces which are in motion relative to each other. The novel aspect of the work is the appearance...
Bifurcations and Chaos in Structural Control
We study a harmonically forced oscillator with nonlinear soft spring subjected to a linear feedback control with time delay. This system can be written as a three dimensional dynamical...
Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...
A Hydraulic Study of Venous Valve Closure
The functions of the veins is to convey blood from the periphery to the heart. The distribution and transportation of blood between different parts of the body is regulated by a host of...
Interaction Effects in the Hybrid Control of Euler-Bernoulli Beams
The effect of viscous and Voigt damping upon the open loop response of simple continua such as Euler-Bernoulli beams is well understood. However, when attempting to control a distributed...
Recent Findings in Active Structural Control
Over the past decade, tremendous advancements have been made in the development of structural control paradigms and in the necessary supporting technologies. The fundamental paradigm that...
Lumped Parameter Model for the Dynamics of the Pulmonary Circulation
The pulmonary circulation is a low pressure system such that respiration has an important effect on pulmonary hemodynamics and has to be taken into account when predicting its behavior....
A Multiple Disk Centrifugal Pump as an Artifical Ventricle
A pulsatile, multiple disk, centrifugal pump has been analysed and tested for potential use as an artificial ventricle. The pump is similar to a Tesla Turbine design which consists of...
Vacuum Melting and Mechanical Testing of Simulated Lunar Glasses
Lunar silicate glasses may possess superior mechanical properties compared to terrestrial glasses because the anhydrous lunar environment should prevent hydrolytic weakening of the strong...
Coastal Engineering Practice
This proceedings contains 70 papers presented at the American Society of Civil Engineers Specialty Conference Coastal Engineering Practice '92 held at Long Beach, California,...
Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....
Urban Development on Alluvial Fans
An increasing number of developments has been planned in areas subject to flood hazards. To protect developments from flood damage and to prevent accumulated negative effects on floodplains,...
