Improving Dynamic Load Balancing Under CORBA with a Genetic Strategy in a Neural System of Off-line Signature Verification

A flat plate solar boiler, having one face which is exposed to solar radiation to heat a liquid within the boiler, also has its opposing face, or the dark side of the boiler, indirectly heated by solar radiation thereby to minimize heat losses from the boiler and to apply further input heat to the boiler. The dark side or second face of the solar boiler is indirectly heated through a metallic plate which is in conductive engagement with the second face of the boiler, extends beyond at least one of the side edges of the boiler, and has a radiation absorptive material on an extension portion of the plate facing the sun. In an alternative embodiment, the second face of the boiler is heated by use of a second solar boiler which is disposed in laterally spaced relation to the first boiler to provide a heated liquid which is circulated past the second face of the first boiler.
