In this study, it is split into two main steps. First, an analytical design is proposed to define the desired parameters with affects of different flux air gaps. Then, a finite element approach is introduced to simulate magnetic field quantities (such as inductance, fringing flux, magnetic flux density, electromagnetic force, current, voltage) of the SRs.

In this paper, the author proposes a new approach (method) to design the pile raft foundation to optimize the number of piles required and suit the geology for each specific building. In which the first the required minimum number of piles with a given safety coefficient (of the pile) is determined then simulates (digitizes) the interaction of pile raft foundation with the ground by the finite element method (FEM) to design the foundation with different load options.

The purpose of this work is to offer a method for detecting structural damage utilizing the standardized index of the beam's deflection influence line difference as input data for the evaluation procedure. The displacement influence line used in the evaluation is calculated using the findings of the behavior analysis of the reinforced concrete beam's finite element model when subjected to a moving load.
