Vibration of base isolated machine foundations has been studied using the Scaled
Boundary Finite Element Method (SBFEM) and the cone model method. The
dynamic stiffness of soil supporting rigid massless foundation was determined. This
stiffness is of complex value. The real part represents the reflected energy of the
restoring and inertial forces while the imaginary part represents the energy dissipated
within the endless extent of the soil as a geometric damping. The effect of geometric
and material properties of soil upon the real and imaginary parts of the dynamic
stiffness was determined and represented in terms of dimensionless charts for the
frequency range of interest. Results have shown tha
his paper presents the design of a sliding mode controller for an uncertain model of a TORA system (Translational Oscillations with a Rotational Actuator) as a two DOF underactuated mechanical system. The switching function is selected to make the TORA system an asymptotically stable mass-spring system with a nonlinear damping effect when the sliding mode controller constrains the state to the sliding manifold. This sliding mode controller is derived here according to a new formula consisting of continuous and discontinuous parts. The main obstacle in the controller design is the uncertainty in the switching function, which appears in the controller formula. The sliding controller is found effective in bringing the system state to the ne

treatment time on the removal efficiency were studied in batch and continuous mode.It was found
that the higher removal efficiency (99%) achieved at pH of 7.5 for Al/Al electrodes while for iron
electrodes at pH 8 in the batch mode.
The removal efficiency increased and the treatment time decreased with increasing the current

Contingency analysis is a valuable tool for a reliable planning and secure operation of a power system. Centingency analysis techniques must consider the impact of voltage effects as well as line flow effects. If the potential outage of a line or a generator would result in the overl rload of another line, then the system is said to be vulnerable. Without line overloading correction it may cause cascade outages and lead to failures in the whole system.
An efficient contingency analysis model for detecting both branch MVA flow violations and bus voltage limit violations is presented. A fast technique has been developed for automatic contingency ranking and selection of contingency cases for a power system contingency analysis stud

Antoon, considered as one of the most internationally recognized Iraqi writers, wrote this dystopian, war novel in Arabic and translated it to English. Antoon’s emphasis placed on literature acting as an oppositional political voice has, in turn, created its own form of censorship inside the fictional world and outside the actual state censorship during Saadm Hossein reign. Thus, particular political messages within literary texts, like I’jaam, have been received with critical attention. The writing culture in Iraq has established an atmosphere in which literary criti
