Abstract: Conventional ground surface insulation can be used to protect power line foundations in permafrost regions from the adverse effects of seasonal freezing and thawing cycles. But previous studies ...

Abstract: In this paper, transient heat conduction between a line heat source and a semi-infinite medium (representing a foundation of a power transmission tower and the surrounding ground) is analyzed ...

Abstract: We report on the free and harmonically forced vibration responses of a rigid block rotating on a rigid surface. For free vibration, we compare the approximate quarter period for an initially open block with the exact quarter ...
