Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
The Effect of Wave Grouping on the Characteristic Wave Height
Wave data from two field stations and from the laboratory tests have been analyzed. The groupiness factor is used to categorize the wave data for the discussion of the correlation between...
Intermittent Kinematics for Nonlinear Random Waves Near Ocean Surface
Taking into account the fluctuations of the free surface for points in the vicinity of the still water level, this study analytically calculates the first four moments of wave velocity...
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...
Flexible Porous Breakwater
This is a theoretical study of the reflection and transmission of linear waves by a flexible, porous and thin beam-like breakwater held fixed in the sea bed. The breakwater is idealized...
Soil Behavior from Unconventional Loading Conditions
Random and sinusoidal loading conditions were used in this study to determine the soil moduli and the damping ratios of cohesive soil samples. Test results showed some differences between...
Screen Breakwaters
The diffraction of water waves by an offshore breakwater consisting of an infinite row of equally-spaced vertical screens is investigated theoretically. The reflected and transmitted wave...
Water Wave Generated by a Porous Wavemaker
A vertical porous wavemaker sitting in an infinitely long channel of constant depth is studied. The wavemaker performs horizontal oscillatory motion. A simplified analytical approach for...
Three-Dimensional Thermal Jump in Stratified Cooling Channel
This study is concerned with basic properties of three-dimensional thermal jumps. Temperature measurements obtained in three-dimensional thermal jumps are presented. The jumps analyzed...
Detection of Cracks in Reinforced Concrete Cans
The Acoustic Emission Technique (AET) is known as a good possibility for non destructive detection of cracks in metal down to very small dimensions. To use AET for concrete, an efficient...
Wave Induced Vortex Near Seashore
The vortex motion behind submerged breakwaters in the nearshore region is studied. The RCPWAVE model (Ebersole et al., 1986) is used to calculate the wave field and thus the radiator stresses...
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...
Effect of Water on the Consolidation of Crushed Rock Salt
The consolidation behavior of crushed rock salt, as the backfill in the under-ground disposal of nuclear waste, will be important in controlling room closure rates and local permeability....
Similarity Solutions of Starting Jets and Starting Plumes
Similarity solutions of the starting jets and the starting plumes are obtained using a one dimensional model based on the top-hat profiles and the symmetry assumption for the velocity...
Pulmonary Artery Velocity Profiles in Young Lambs
This report describes progress made in our laboratory in examining pulmonary artery velocity patterns in normally maturing lambs. Lambs from four age groups were selected for study--2...
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....
Integrity Testing of Concrete Elements Using Surface Waves
The Spectral Analysis of Surface Waves (SASW) method is a nondestructive testing procedure which has been extensively used to determine in situ the elastic moduli of soils and pavements...
Scattering of Waves by Steel Reinforcement in Concrete
The application of wave-sensing methods to the non-destructive evaluation of concrete structures requires often the use of simple (or at least tractable) models for the solution of the...
The Small Mars Rover
Mars rover is one of the principal technical means intended for studying the surface of Mars. The first Mars rover was delivered to the Mars surface in 1971 and was designed for studying...
