Ali, Taifour; Abbas, Abdelaziz Y. M.; Osman, Ekram Hassabo Abaid
The induction motor drive is a dynamic nonlinear system with uncertainty in the machine
parameters. The aim of this study is to improve tracking performance of the induction motor drive. A method
for controlling induction motor drive is presented with conventional Proportional-Integral (PI) controller and
Artificial Neural Networks (ANNs) controller. MATLAB/SIMULINK software is used to develop a three
phase induction motor model. Also the performances of the two controllers have been verified. The ANN is
trained so that the speed of the drive tracks the reference speed. It is found that with the use of the ANN
controller the performance and dynamics of the induction motor are enhanced as compared with that of a
conventional PI controller.

Hussein, Rashid A.M.; Xiaomin, Zhu
Bohai Bay Basin,China, is a rift basin developed in Mesozoic-Cenozoic time span.
It was compressionally deformed during Caledonian Orogeny and situated on a Paleozoic platform
“old craton” basement and later subjected to extensional stress and induced major strike-slip
(wrench) fault. The basin opening transpired on a series of half-grabens trending NNE-SSW in
Bohai Bay Basin zone. Models for deformational mechanism and evolution of the Bohai Bay Basin,
China, and its tectonic and stratigraphic history were proposed. Two separate scenarios were set for
the evolution of Bohai Bay Basin: the first is based on the changes in plate convergence rates along
the eastern plate boundary of Eurasia/ Pacific plates which have additional role in the extensional
skin of Bohai Bay Basin in certain stage of extension or rifting and the second is a model of three
major incidents of extensional tectonism: basement pre-rifting, a syn-rift stage, and a post-rift sag
stage were documented for Bohai Bay Basin. The major factor controlling the lacustrine basins is
global eustasy; however, the role of global tectonic played a significant control mechanism in the
evolution and development of Bohai Bay Basin.

This study carried out to assess the effect of increasing bentonite percentage (solid
phase) on rheological properties and filtration loss for water base drilling fluid prepared from
local bentonite (Umm Ali area). Chemical tests were carried out to assess quality of local
bentonite. In this study Carboxymethyle Cellulose CMC is used to increase viscosity and
decrease filtration loss. The major finding showed that when adding 7% of CMC and 7% of local
bentonite, the rheological properties, filter loss and yield point to plastic viscosity ratio will be
within the acceptable range of American Petroleum Institute (API) specifications
