Depression ranges in seriousness from mild, temporary episodes of sadness to severe, persistent depression. Clinical depression is the more severe form of depression, also known as major depression or major depressive disorder.
SCADA (supervisory control and data acquisition) SCADA (supervisory control and data acquisition) is a category of software application program for process control, the gathering of data in real time from remote locations in order to control equipment and conditions. SCADA is used in power plants as well as in oil and gas refining, telecommunications, transportation, and water and waste control. SCADA systems include hardware and software components. The hardware gathers and feeds data into a computer that has SCADA software installed.
Another outstanding difference between SCADA and DCS is that the former maintains a database of previous good values and secure data and control whenever there are slow and undependable communications, which makes it fast for urgent operator display.
