Electromagnetic Model

In order to investigate the law of electromagnetic propagation within microwave heating system, Maxwell's equations are applied to build electromagnetic model of recycled asphalt mixtures. Energy distribution of electromagnetic field in asphalt mixtures is researched based on the Poynting theory. The optimization model of electromagnetic field and structure are established by building relationship between electric field and magnetic field. Experiments of microwave heating allochroic silicagel are performed, which demonstrates the accuracy of electromagnetic field optimization.

Bending Failure

Aiming at the change law of the flexural and tensile strength of the modified steel slag asphalt mixture during microwave heating, the results of this paper are as follows: the microwave heating process can achieve the recovery of the flexural and tensile properties of the modified steel slag asphalt mixture. The number of point bending failure tests continues to increase, and the recovery rate of bending and tensile properties of beams made of modified steel slag asphalt mixture will slowly decrease until the test piece is completely destroyed. The flexural and tensile strength of beams made by microwave heating asphalt mixture cannot be fully recovered, but different asphalt mixtures have different recovery effects. Compared with the ordinary basalt asphalt mixture, the steel slag asphalt mixture before modification has the same bending and tensile repair effect after microwave heating, while the modified steel slag asphalt mixture has the first bending and tensile repair effect after microwave heating increased by 23%.

Abstract This research has studied Wat Poramaiyigawas with the objective to study Mon identity in Siam context through Buddhist architecture during the transition from Old to New Siam. The essence of this research is set upon the concept of Stuart Hall's Representation Theory which indicates that architecture is constructed with the purpose to express the creator's concept, with the method of studying related historical information and physical field study. Wat Poramaiyigawas had been abandoned before it was restored by the Mon immigrants in Thonburi Kingdom until it was later sponsored by Siamese aristocrats for major reconstruction. During the social transition from a conservative society to a modern one which had the Western world as the prototype, temple reconstruction or building of the Mon the subordinates of Siam where changes were taking place, the Mon had to follow Siamese aristocrats' view showing not only for the purpose of ideological significance of their belief or Buddhist function, but also was the venue for creating the ideological and conceptual meaning which were created symbolically through art and architecture according to views reflecting identity of the creator in that period than Mon people who were the real users.
