Wave Loading Linearization for Offshore Structures
The linearization of Morison-type wave loading is to replace u|u| by cu, where u is a zero mean, stationary Gaussian random process and c is a constant. In the present study an optimal...
A Contact Problem Modeling the Squeeze-Film Mode of Synovial Joint Lubrication
A contact problem modeling synovial joint lubrication under squeeze-film conditions is studied. In this model, the thin synovial fluid layer is incompressible and linearly viscous, and...
Buckling Loads of Columns Made of Viscoelastic Materials
This is about the developing of relationships for predicting the change of buckling loads of columns made of viscoelastic materials under different loads. When a columnlike structural...
Cumulants of the Nonlinear Combination of Independent Random Variables
A random variable of interest is often the sum of linear or nonlinear combinations of many independent random variables. In calculating the statistics of this random sum, advantages of...
Flexural and Extensional Motion of Moderately Thick Laminated Composite Plates
A general theory of flexural and extensional motion of moderately thick laminated composite plates is developed for linear elastic materials and small deformation. Interlaminar stresses...
Detection of 2-D Nearshore Wave Patterns Using Linear Prediction and SAR Data
Extraction of wave parameters such as wavelength and direction on radar images is normaly done using fast Fourier transforms (FFT) on typical image size of 256 ? 256 which may not be appropriate...
Beach Change Magnitudes in Relation to Dynamic Phases on Dissipative Coasts
Dissipative-prone beaches are statistically and aethestically the most significant on open sea sandy coasts. These beaches owe their widespread occurrence to their temporal stability....
Infragravity Waves, Longshore Currents, and Linear Sand Bar Formation
A new hypothesis regarding the role of infragravity waves in controlling the formation and offshore migration of linear (2-dimensional) sand bars is presented. The hypothesis is dependent...
A New Method for Calculating a Mathematical Expression for Streamflow Recession
An empirical method has been devised to calculate the master recession curve, which is a mathematical expression for streamflow recession during times of negligible direct runoff. The...
Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...
Integration of Cost and Schedule Control
This paper presents cost control and schedule control relationships in an integrated manner for an activity/cost account that has a single output scheduled to be produced in a linear,...
Properties of Small-Scale Waves in Sheared Gas-Liquid Flows
Small wind-generated waves are examined theoretically and experimentally in a small laboratory flow system, at conditions close to neutral stability in an attempt to better characterize...
New Experimental Results on the Parameters Influencing Air-Sea Gas Exchange
Gas exchange experiments from large linear and circular facilities are presented which provide some more insight into the influence of waves on the gas exchange process. The experimental...
Stereo Vision Onboard a Vehicle for Obstacle Detection
We show how two linear cameras, mounted behind the windscreen of a car, can be used to detect the obstacles on the road in real time, even with small computer architectures. Results of...
Application of Control Theory to Regulate Traffic Flow on Periurban Ringways
Two on-ramp metering strategies are compared by a simulation study for the Boulevard Peripherique in Paris. The first one is a local strategy, based on linear feedback control theory....
