Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...

Adsorption of Lindane onto Whole Soil and Soil Organic Fractions
The work presented here investigated interactions of the subject pesticide with whole soil and select soil organic fractions and evaluated the commonly applied assumptions that adsorption...

Composting: Computing the Right Recipe
A pinch of this and a pinch of that is an adequate instruction for most good cooks. But for composting, facility managers need a recipe that specifies the right ingredients and exact amount,...

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...

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,...

Effect of Gas Flow on Physical Absorption
Air blowing over a liquid surface can greatly increase the rate of physical absorption of a gaseous component. This increase is associated with the initiation of waves and a change in...

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...

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...

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...

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....

Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...

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

A Stochastic Clustering Model for the Occurrence of Large Earthquakes Along the Central Peruvian Margin
A stochastic model of a process of cluster centers and subsidiary cluster member processes is presented for the occurrence of large earthquakes along the Central Peruvian Margin. In the...

Development of a Nonlinear Stochastic FEM and its Application
A basic formulation is developed for the nonlinear stochastic finite element method. It is based on the perturbation method and retains its advantage, namely that a nonlinear finite element...

Non-Linear Stochastic Finite-Element Analysis of Continua
Stochastic equivalent linearization, coupled with appropriate endochronic idealizations of the constitutive law, is extended in this paper to analyse the dynamic response of non linear...

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...

Random Vibrations of Geometrically Nonlinear Finite Element Plates and Shells
A finite element formulation combined with stochastic linearization and normal mode methods are developed for the study of geometrically nonlinear random vibration characteristics of plate...

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...
