26. Studies using wind tunnel to simulate the Atmospheric Boundary Layer at the Alcântara Space Center
Abstract: The Alcântara Space Center (ASC) region has a peculiar topography due to the existence of a Coastal cliff, which modifies the atmospheric boundary layer characteristic in a way that can affect rocket launching operations. Wind tunnel measurements can be an important tool for the understanding of turbulence and wind flow pattern characteristics in

27. Sistema para gerência autonômica de grades computacionais
Grid computing technologies are being applied as an affordable method to cluster computational power together. These structures aim to support service applications by grouping devices and shared resources in one large computational unit. However, the management complexity grows proportionally to the number of resources being integrated. From a given point up
