Oxygen Enriched Atmosphere Roasting

The possible benefits of oxygen enriched atmosphere roasting have been known to metallurgists for many years, but only since the development of equipment and processes to produce cheap oxygen in very large amounts has much ser­ious consideration been given this matter

Tearing the Guts Out of the Wehrmacht: A Re-Examination of the Russo-German War

Nazi Germany invaded the Soviet Union on 22 June 1941. Hitler’s plan to annihilate Germany’s Eastern neighbor and populate the vast Russian expanse with his own people was as ambitious as it was adventuristic. Although it began successful, the Russo-German War quickly devolved into a quagmire as Russian troops outfought their German opponent and beat them back to Berlin. Contrary to prevailing historiography, the Wehrmacht’s loss on the Eastern Front cannot be solely attributed to a failure to equip German troops with proper winter clothing, an inadequate logistics network or Hitler’s interference in military decisions. For an army that had enjoyed rapid gains during late 1930s and 1940, only an enhanced tactical revolution, superior armor and a more aggressive martial ethos explains how the vaunted German military suffered ignominious defeat at the hands of what many consider a third-rate adversary

Aspects of mechanics of nonNewtonian fluid

Timing Control System

A timing control system is disclosed which is particularly useful in connection with simulated mortar shells. Special circuitry is provided to assure that the shell does not over shoot, but rather detonates early in case of an improper condition; this ensures that ground personnel will not be harmed by a delayed detonation. The system responds to an externally applied frequency control code which is configured to avoid any confusion between different control modes. A premature detonation routine is entered in case an improper time-setting signal is entered, or if the shell is launched before completion of the time-setting sequence. Special provisions are also made for very early launch situations and improper detonator connections. An alternate abort mode is provided to discharge the internal power supply without a detonation in a manner that can be externally monitored, thereby providing a mechanism for non-destructive testing. The abort mode also accelerates the timing function for rapid testing

An intelligent processing environment for real-time simulation

The development of a highly efficient and thus truly intelligent processing environment for real-time general purpose simulation of continuous systems is described. Such an environment can be created by mapping the simulation process directly onto the University of Alamba's OPERA architecture. To facilitate this effort, the field of continuous simulation is explored, highlighting areas in which efficiency can be improved. Areas in which parallel processing can be applied are also identified, and several general OPERA type hardware configurations that support improved simulation are investigated. Three direct execution parallel processing environments are introduced, each of which greatly improves efficiency by exploiting distinct areas of the simulation process. These suggested environments are candidate architectures around which a highly intelligent real-time simulation configuration can be developed
