For decades Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS) have used computers to monitor and control physical processes in many critical industries, including electricity generation, gas pipelines, water distribution, waste treatment, communications and transportation. Increasingly these systems are interconnected with corporate networks via the Internet,...

Quality assurance (QA) is the total process whereby the quality of laboratory reports can be guaranteed. The term quality control covers that part of QA, which primarily concerns the control of errors in the performance of tests and verification of test results. All materials, equipment and procedures must be adequately controlled. Culture media must be tested for sterility and performance. Eac...

A sizeable number of deliveries still take place with the assistance of Traditional Birth Attendants in Nigeria. This study aims to determine the factors that determine the referral practices of the TBAs in Ilorin of high risk and complicated pregnancies. This descriptive study was conducted among all the 162 registered TBAs in Ilorin that were traceable using pre-tested semi-structured intervi...

We present experimental results for the effect of an increased supervisory signal power in a high-loss loopback supervisory system in an optically amplified WDM transmission line. The paper focuses on the investigation of increasing the input power for the supervisory signal and the effect on the copropagating WDM data signals using different channel spacing. This investigation is useful for de...

Supervisory control and data acquisition systems (SCADA) are widely used in industry for supervisory control and data acquisition of industrial processes. The process can be industrial, infrastructure or facility. With the advances of electronic and software technologies, the SCADA systems are widely used in industrial plant automation. It provides an efficient tool to monitor and control equip...

In this paper, we propose a framework for real time monitoring and diagnosis of automated vehicles in an IVHS. The supervisory control methodology proposed here is concerned with fault detection, fault isolation, and control reconfiguration of the many sensors, actuators and controllers that are used in the control process. This supervisory control architecture operates at two levels of the AVC...

This research is about the ASN supervisory strategy by West Aceh District BKPSDM. an idea that arranged before carrying out action or in doing something so what goal can be achieved. So results achieved are maximized and efficient taking there must a used. study aims to see how far has been carried BKPSDM towards ASN. uses qualitative methods data collection through interviews, observation, doc...
