SWP.exe is a standard interface for the calculation of thermodynamic and transport properties of fluids. This software program was developed around 2007 - 2011 (aerryawan gerry), Energy Section, PT. Jaya CM.
Each thermodynamic library implements one or more thermodynamic models for several thermodynamics Analysis and optimization heat and electricity production system
State functions for water/steam calculations are: IAPWS Industrial Formulation 1997 (IAPWS-IF97)
Leakage of stray currents into the ballast bed and earth can be a significant problem if the cables running from the rails are electrically connected to the impedance bond housing case and the case is in contact with the earth. This can occur if the cases are mounted on reinforced concrete where the mounting bolts contact the re-bar, if the bottom of the case is resting on concrete, or if dirt and debris accumulate between the bottom of the case or signal equipment and the concrete.
An accumulation of ballast, dirt, or other debris around the locations where the cases or signal equipment are installed along the right-of-way can also provide a path for current leakage. This type of installation can result in a continuous maintenance problem if an effectively high rail-toearth resistance cannot be achieved.
Some impedance bonds are located outside the tracks on timber ties to eliminate points of possible contact with earth. The center taps of the impedance bonds should be insulated from the mounting case. Switch machines also must be electrically isolated from the running rails.
Any embedded switch machines and junction boxes need to be insulated from the rail and insulated from concrete or other material.
Dissimilar metals shall be isolated or separated for corrosion control. Materials selection needs to consider the environmental conditions where the items are being installed.
Yard tracks should be isolated from the main line tracks to reduce corrosion.
DESCARTES : 'THERE IS NO GOD IN THE COSMOS. GOD IS IN HUMAN CONSCIOUSNESS'
René Descartes has insisted that the intellect alone could provide us with the certainty he sought. Faith told us nothing that could not be demonstrated rationally.
Descartes argued that god could be known more easily and certainly than any of the other things in existence. Descartes has attempted to establish an equally analytical demonstration of god's existence, but he found no god in cosmos. There was no design in nature. Universe was chaotic and there was not a single sign of design, or intelligent planning.
Descartes found evidence of god in human consciousness; even doubt proved the existence of the doubter! We cannot be certain of anything in the external world, but we can be certain of our own inner experience. We could not arrive at the idea of imperfection if we did not have a prior conception of perfection.
A perfection that did not exist would be a contradiction in terms. Our experience of doubt, therefore, tells us that a supreme and perfect being must exist. Descartes' god is the god of the philosophy, who did not interfere with the worldly affairs. This god has made known of himself not through miracles, but in the eternal laws he has decreed.
