Leakage may occur because of time corrosion in the tube raw materials. To reduce the negative consequences of this leak, an effective leak detection system is used to prevent serious leakage accidents and damage in oil pipelines. Buildings, ecosystems, air pollution, and human life are all at risk in case of leakage occurs which could lead to fires. This paper introduces one of the research methods for the detection of pipeline leaks with a particular focus on software-based methods. The computer board interface (CBI) and wireless sensor networks have been used beside Arduino as a micro-monitor for the entire system. ZigBee is also utilized to send read data from sensors to the monitoring system displayed on the LabVIEW graphical user interface (GUI). The operator can take direct action when a leak occurs. The effectiveness of the leakage monitoring process and its practical use are demonstrated by the introduction of compu...

The hardware system has a series results from scientific projects carried out at the Protection and Control Laboratory of electrical power system. Models interface supports MATLAB / Simulink control system, and LabVIEW interface, and others. This gives not only Simulink, but also provides full support for any test software in real time, which uses the same interface. To run in the Hardware-in-the-Loop (HIL) simulation and the model has a measurement of the variables of the devices, whose receive the calculated variables in the form of mathematics. Testing has an integral part of modern controller development. Hardware-in-the-Loop (HIL) simulation plays a prominent role as test method. In HIL, the implemented controller is tested against a computer model of the process. Besides the communication between simulation and controller, HIL requires their synchronization. Besides the communication between simulation and controller, the program is based on the MATLAB / Simulink package including libraries, while the hardware installed measuring cards segment consists in PC computers, amplifier CMS 156 dedicated and matching circuit. The last section of this article and a brief description of possible improvements expected for simulation in the future. The study involves xPC Target as a real time operating system in charge of executing a control task is focusing on the built in control and simulation capabilities. We will try to see how accurate and how fit xPC Target is for multiple Targets control, here the xPC Target is used as an operating environment for real time simulation in electrical power sub stations system.

This circuit contains the RX, TX serial data to convert this wave of input microcontroller which is programmed to receive the data of controlling PLC to mobile phone and send the SMS to the input of driver. This driver consists from transistor array circuit to operate the relays that are connected with the device; the messages are written in a code that is received by the microcontroller for each address of the device. The programmed microcontroller can read the messages which are stored in the Inbox of the SIM Card after reading it. The program then clears the Inbox contents to keep the inbox empty and ready to receive the next message. This system is used in a wider range where the PLC has to control the pump stations and many embedded control applications by using the GSM technology.

It also defines the working principle, calculations and design, challenges and applications beside the future scope of using Overshot and undershot waterwheels. In order to cover the enlarged demand for power in rural areas of Iraq, generated hydropower from waterwheels are one of the most promising solutions to produce electricity. Modern water wheels are made from steel which promising no harmful effects on the environment. In this research, two types of water wheels (Overshot and Undershot) are used to produce the electricity through fastening the waterwheel to a generator with the support of a belt and pulley arrangement, so the electrical energy resulted from mechanical energy. The full bridge rectifier is used to transfer electricity in its most effectual form while the regulator is used to adjust the current.

To cope with this, among other things, the multi-carrier orthogonal frequency division multiplexing (OFDM) in combination with coherent reception is under discussion for future systems. However, as OFDMS systems are sensitive to nonlinear perturbations, this work presents Procedures that reduce such influences. Thus, impairments of the channel estimation are examined by transmitter-side quantization errors and possibilities are shown of reducing them or even eliminating them altogether. In addition, the influence of the non-linear characteristic of the electro-optical modulator is studied and demonstrated that nonlinear distortions can be significantly reduced by digital preprocessing of the transmission signal. On the receiver side, this work deals with synchronization procedures for frame detec...
