This paper investigate a sensorless speed control of a separately excited dc motor fed from a buck type dc-dc converter. The control system is designed in digital technique by using a two dimension look-up table. The performance of the drive system was evaluated by digital simulation using Simulink toolbox of Matlab.
Imam Ali Bin Al-Hussain Bin Ali (Zain Al-Abedien) (pbuh) is famous in worship, afraid from God , in spite of his origin that is related to prophet Mohammad , he felt tired of worship until he had arrived to be sick ,he sometimes felt patient and looked yellow when he would be in front of God . It is important to shed light on his worship as describing him the forth Imam of the twelfth ones .What he had said and what he had done was as a guide to whom who want to be won in this life , finally, the research concluded that faith , worship deals with interior feeling lead to worship not by increasing them or by thinking , but it is as interiorly faith.
إن قراءة شبه متأنية لبعض مواقف الاِمام السجاد( عليه السلام ) من الظالمين وأعوانهم ، وكذلك مواقفه من بعض الحركات الشيعية التي تفجّرت في زمانه ، وكيف انتقل من مرحلة التقية المؤلمة إلى مرحلة المواجهة الساخنة ، لا سيّما بعد أن استنفذ دوره التبليغي الصامت ، وارتأى أنّه لابدّ أن ينتقل من المرحلة السلبية السرية الصامتة إلى مرحلة اعلان المعارضة ، خاصة وإنّه أدرك أن خصومه عن دوره في تأليب الاُمّة ضدهم وتحشيد غضبها وإ

records and data are also used in other processes like customer relationship management and accounting
operations.It is incredibly challenging to use and extract valuable and meaningful information from these data
and records because they are frequently enormous and continuously growing in size and complexity.Data
mining is the act of sorting through large data sets to find patterns and relationships that might aid in the data
analysis process of resolving business issues. Using data mining techniques, enterprises can forecast future
trends and make better business decisions.The Apriori algorithm has bee
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

... Show MoreThe ability of beans (Phaseolus vulgaris L.) to uptake three pharmaceuticals (diclofenac, mefenamic acid and metronidazole) from two types of soil (clay and sandy soil) was investigated in this study to explore the human exposure to these pharmaceuticals via the consumption of beans. A pot experiment was conducted with beans plants which were grown in two types of soil for six weeks under controlled conditions. During the experiment period, the soil pore water was collected weekly and the concentrations of the test compounds in soil pore water as well as in plant organs (roots, stems and leaves) were weekly determined.
The results showed that the studied pharmaceuticals were detected in all plant tissues; their concentration
