Safe-Load-Limit of Plates in Cylindrical Bending
The derivation of a closed-form expression for the viscoelastic critical load of long thin plates undergoing cylindrical bending and made of a linear time-dependent 'solid'-type...

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...

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....

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...

Concentration Measurements in Dense Leachate Plumes Using a Gamma Radiation System
An automated, nonintrusive technique is discussed that determines salt concentrations in dense leachate plumes. The dense plumes were introduced from a line source into a relatively narrow...

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....

Rainfall-Reaeration Effects
The effect of rainfall intensity on reaeration has not been adequately reported in the literature. It is clear that rainfall causes surface turbulence and increases reaeration, and a significant...

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...

Methods for Designing Hydraulic Aquifer Remediation Techniques
This paper reports on recent research to develop methods for accommodating uncertainty in designing hydraulic remediation systems for contaminated aquifers. The methods rely respectively...

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...

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...

Vibrations of Linearly Tapered Cantilever Beams
Originally published in: Journal of the Engineering Mechanics Division, ASCE, EM2, April 1962, pp. 95-123...

Mean Square Stability of Linear Gyroscopic Systems Under Combined Harmonic and Stochastic Excitations
This paper examines the mean square stability of linear gyroscopic systems under both harmonic and stochastic parametric excitations. The intensities of both excitations and correlation...

Consideration of Non-Gaussian Hysteretic Response Properties of MDOF-Systems by Use of Equivalent Linearization
The stationary stochastic response of nonlinear MDOF-systems is analysed by equivalent linearization (EQL). Non-Gaussian properties of the state vector y are taken into account by utilizing...
