Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Rapid Filling of Reservoirs
The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels,...
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
The Transport of Crude Oil Under Saline Ice
A mathematical model was developed to describe the forces acting on an oil slick under saline ice in the presence of a water current. The model was verified through a set of laboratory...
Finite Element Discretization for Mixed-Mode Fracture Problems
The finite element discretization of mixed-mode problems in fracture mechanics is investigated. The characteristics of the mesh near the crack affect the accuracy of the finite element...
Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...

A procedure is presented to eliminate the error introduced in the step-by-step numerical integration of the equations of motion of hysteretic bilinear systems subjected to earthquake excitations...
Interactive CAL Modules for Mechanics of Solids
Traditionally the basic engineering course in 'Mechanics of Solids' has proven to be a challenge to both the students and faculty, for although the fundamental...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Mechanics of Crack Propagation in Stiff Clays
Many stiff clays forming part of natural slopes and earth dams exist in the fissured state. When these cracks are subjected to gravity induced normal and shear stresses they may propagate....
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
Qualitative Physics and the Prediction of Structural Behavior
A key need in the application of expert systems to structural engineering design is the ability to predict structural deformation and stresses in the absence of a quantitative model. The...
