In this paper, the speed control of the real DC motor is experimentally investigated using nonlinear PID neural network controller. As a simple and fast tuning algorithm, two optimization techniques are used; trial and error method and particle swarm optimization PSO algorithm in order to tune the nonlinear PID neural controller's parameters and to find best speed response of the DC motor. To save time in the real system, a Matlab simulation package is used to carry out these algorithms to tune and find the best values of the nonlinear PID parameters. Then these parameters are used in the designed real time nonlinear PID controller system based on LabVIEW package. Simulation and experimental results are compared with each other and showe

Artificial pancreas is simulated to handle Type I diabetic patients under intensive care by automatically controlling the insulin infusion rate. A Backstepping technique is used to apply the effect of PID controller to blood glucose level since there is no direct relation between insulin infusion (the manipulated variable) and glucose level in Bergman’s system model subjected to an oral glucose tolerance test by applying a meal translated into a disturbance. Backstepping technique is usually recommended to stabilize and control the states of Bergman's class of nonlinear systems. The results showed a very satisfactory behavior of glucose deviation to a sudden rise represented by the meal that increase the blood glucose

Background: Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply; the bone structures then collapse, resulting in bone destruction, pain, and loss of joint function. AVN is associated with numerous conditions and usually involves the epiphysis of long bones, such as the femoral head. In clinical practice, AVN is most commonly encountered in the hip. Early diagnosis and appropriate intervention can delay the need for joint replacement. However, most patients present late in the disease course. Without treatment, the process is almost always progressive, leading to joint destruction within 5 years.Treatment of a vascular necrosis depends mainly on early diagnosis which mainly base

A two-dimensional depth-averaged hydrodynamic model and a two-dimensional water
quality parameters transport model were developed to simulate the characteristics of Al
Huwayza Marsh, which is considered the largest and most important marsh in the south of
Iraq. The hydrodynamic model for Al Huwayza Marsh was built by using RMA2 model,
while the water quality model was built by using RMA4 model. These two models are part of
Surface Water Modeling System, SMS, software package.
To investigate the effect of the marsh boundary configuration on the variation of the
velocity pattern and the water quality within the marsh, both of the hydrodynamic and the
water quality models were applied to three cases of boundary confi

The world witnesses in this period of time the appearance of various structural concepts. Technology and other factors helped in the development of many architectural forms that carried technological character manifested through efficiency, lightness, most of these forms are tensile structures. In spite of the fact that the use of tensile structures is still in doubt and suspicion, they started to appear in Arab countries and neighbouring regions, after they had been affected by the technological achievements of the technologically developed countries, and started to use such structures in their local buildings, especially if the factors needed to adapt such kind of
structures are present on their lands, also the minds that can deal

The electrochemical behavior of iron and steel in alkaline media is complex,not well understood.It is
difficult to determine corrosion rates of steel in high pH solutions by extrapolation of Tafel curves.Polarization resistance (Rp) must be determined in some other way.In this study an attempt was made to find (Rp) values of steel corroding in saturated Ca(OH)2 by anodic currents impressed galvanostatically to the steel from a counter electrode placed together with a reference electrode(I.e. impressed anodic current densities were (10,20,40,and 100µA/Cm2 and duration time was about 25 minutes). It was found that this rapid and non destructive polarization technique yields accepted and reasonable information on corrosion behavior.

This study explains how nickel oxide (NiO) nanoparticles are made using a plasma jet method at normal air pressure, using a direct current (DC) power supply set to a steady voltage of 13 kV. The properties of the plasma were studied using optical emission spectroscopy (OES) while changing the flow rates of argon gas to 0.25, 0.75, 1.75, and 2.25 L/min over a period of 6 minutes. NiO thin films were deposited on glass substrates and annealed at 270 °C.
