The influence of immobilized biomass and particle size on the fluid dynamics of an anaerobic fluidized bed reactor
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2008)
Fluid dynamic analysis is an important branch of several chemical engineering related areas, such as drying processes and chemical reactors. However, aspects concerning fluid dynamics in wastewater treatment bioreactors ...
Dependence of equatorial F region vertical drifts on season and solar cycle
(American Geophysical Union, 1979-10-01)
Vertical drift measurements have been made at Jicamarca for more than half a solar cycle. The data from periods of high and low activity are appreciably different. Daytime drift velocities during sunspot minimum are usually ...
Trajectory-tracking control of a planar parallel robot using generalized predictive control with constraints
(Cartagena de Indias, 2020)
This paper presents the generalized predictive control with constraints, implemented to a planar parallel robot in order to calculate and track the desired trajectory of the end-effector of this robot. The manipulator is ...
The wind of rotating B supergiants, I : domains of slow and fast solution regimes
(IOP Publishing, 2016-05)
In the scenario of rotating radiation-driven wind theory for massive stars, three types of stationary hydrodynamic solutions are currently known: the classical ( fast) m-CAK solution, the Ω-slow solution that arises for ...
A Vortical Dawn Flank Boundary Layer for Near-Radial IMF: Wind Observations on October 24, 2001
(American Geophysical Union, 2014-06)
We present an example of a boundary layer tailward of the dawn terminator which is entirely populated by rolled-up flow vortices. Observations were made by Wind on October 24, 2001 as the spacecraft moved across the region ...
Water flow in high-speed handpieces
(2005-05-01)
Objectives: This study measured the water flow commonly used in high-speed handpieces to evaluate the water flow's influence on temperature generation. Different flow speeds were evaluated between turbines that had different ...
