TPO Roof Replaces Leaking Inverted Roof-Membrane Assembly System. By Dan Hounsell, Editor July 2010 - Roofing Article Use Policy. The problematic roof was an inverted roof-membrane assembly (IRMA), which consisted of a built-up membrane installed over a structural concrete slab and topped by insulation.
DVI vs. VGA. VGA and DVI connectors are used to transmit video from a source (like a computer or tablet) to a display device (like a monitor, TV or projector). The main difference between VGA and DVI is in the way the video signals travel. VGA connectors and cables carry analog signals while DVI can carry both analog and digital.
The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so it is not possible to connect a male DVI-I to a female DVI-D by removing the four analog pins. It is possible, however, to connect a male DVI-D cable to a female DVI-I connector. Many flat panel LCD monitors have only the DVI-D connection so that a DVI-D male to DVI-D male cable will suffice when connecting the monitor to a computer's DVI-I female connector.
