Stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. The complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. The curr...

In this paper, we give an analytical approximate solution for an integro- differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields is considered. The homotopy analysis method (HAM) is used for solving this equation. Several examples are given to reconfirm the efficiency of these algorithms. The results of applying this procedure...

High-performance electric motors and their associated controllers are widely used in motion control applications. Feedback devices are employed to measure position and estimate motor velocity. The control system closes position and velocity loops using these feedback devices. A number of control schemes have been employed in industrial applications including closing a velocity loop within a pos...

Discusses the relation between cybernetics and architecture and pays tribute to Gordon Pask’s role and influence. Indicates Pask’s contribution to an increasingly environmentally responsive architectural theory that may lead to a more humane and ecologically conscious environment.

A model of time-consistent procrastination is developed to assess the extent to which the observed behavior is compatible with rational behavior. When a finite work requirement must be completed by a deadline, the remaining time for leisure is an exhaustible resource. With a positive rate of time preference, the optimal allocation of this resource results in more hours spent working (and fewer ...

This paper is concerned with the recent wave of Hong Kong immigrants into Van couver. The stage is set for this discussion by first explaining some background behind Canadian imm igration policy and then discussing the history of Chinese immigrants in Vancouver. From these discu ssions we are informed that Canadian immigration policy was historically ethnocentric and only began to change in the...
