ABSTRACTA fully three dimensional model has been developed for simulating the thermal behaviour of a RTP furnace. This model consists of two components to achieve the whole analysis. The first component models the radiation heat flux density at the wafer surface as a function of the system geometry, the lamp position and intensity, and the wall reflectivities. The second component solves the heat conduction equation at each point within the wafer using appropriate boundary conditions, including convective cooling which effect depends on the process conditions. A particular attempt is made upon the achievement of a flat temperature profile over the wafer by investigating the system parameters in order to improve the RTP equipement.

City Plan

The article proposes ways to increase the effectiveness of the decision-making process of the tactical level commander while performing tasks in operations in the context of modern warfare by creating a three-dimensional model of a military city plan. The article also highlights adavantages of the 3-dimensional model of a military city plan when compared to a regular traditional paper-based city plan. Performed scientific research allowed us to develop a technological scheme for the creation of the 3-dimensional model of a military settlement plan using CityEngine, a special geo-informational software, aimed at optimizing the decision-making process for a tactical-level commander, which will also significantly improve the existing approach for creating settlement plans. In order to achieve this objective, we carried out partial analysis of the tactical characteristics of the terrain and determined their impact on the combat actions, as well as studied the possibilities for creating a 3-dimensional city plan model by the means of geographical informational systems. Compared to traditional paper-based topographic maps, the improved technique makes it possible to improve the analysis of tactical terrain properties by means of 3-dimensional imaging, to simulate the tactical characteristics of any terrain and to predict their changes in accordance with the effects of combat.
