Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...

Chaos, Fractals and Sensitivity Analysis

Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...

An Analysis of Cavitation Damage in a Francis Turbine Operating Under Small Opening Condition
In this paper some new formulae are derived to estimate the pressure and the relative velocities in the crown and the band regions of the Francis turbine runner operating under any gate...

Kaplan Blade Angle Controller
This paper describes a recently developed computerized Kaplan blade angle controller that is capable of improving turbine performance. Model Tests or Index Tests produce the Three-D-Cam...

Concurrent Nullspace Methods for Multibody Systems
This paper presents a new concurrent multiprocessing algorithm for simulating the dynamics of constrained multibody systems. The systems considered are quite general in nature; they may...

Characteristics of Nonstationary Response of Linear Systems
A new formulation for the statistics of the response of linear systems to nonstationary excitation is developed. Both the process and its envelope are examined and exact statistics are...

Maximum Value Statistics for Transient Response of Linear Structures
The mean and the variance are investigated for the maximum absolute value of a nonstationary process which represents the response buildup of a linear oscillator. The mean and variance...

One Solution for Different Stochastic Systems
It is shown that different dynamic systems under different sets of random excitations can share an identical probabilistic solution. Such systems are said to be stochastically equivalent,...

Comparison Between Linearization and Gaussian Closure
A variety of approximate solution techniques have been developed for analysis of nonlinear systems. The most widely used method has been equivalent linearization. Recently a general closure...

Efficient Probabilistic Structural Analysis Using an Advanced Mean Value Method
An advanced mean-value (AMV) method for probabilistic structural analysis is presented. This method blends the conventional mean value method with the advanced structural reliability analysis...

A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...

Simulation of Acceleration Time Histories Close to Large Earthquakes

Parallel and Distributed Processing in Structural Engineering
Parallel processing is emerging as an effective approach to large scale structural engineering computations. The papers included in this book cover vibration analysis using a parallel...

Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...

An Inline Retarding Basin
This paper discusses the idea of retarding flows within existing right-of-way in a linear basin. This concept is based on longitudinally dividing the right-of-way into two sections. The...

Stochastic Characteristics of Cobble-Gravel Bed Load Transport
Prototype tests of stochastic characteristic of cobble-gravel bed load transport have been done in Dujiangyan reach of Minjiang River in China in 1977-1985. All of 718 sample data from...

Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...

A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...

Implementing a State PMS
Arizona State Pavement Management System (PMS) is described in this paper. Experience shows that many factors must be considered in deciding how to maintain a particular mile of the road...
