Evaluation of biogas biodesulfurization using different packing materials
(2019-03-01)
The packing material selection for a bioreactor is an important factor to consider, since the characteristics of this material can directly affect the performance of the bioprocess, as well as the investment costs. Different ...
Wang-Landau algorithm for entropic sampling of arch-based microstates in the volume ensemble of static granular packings
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-03)
We implement the Wang-Landau algorithm to sample with equal probabilities the static configurations of a model granular system. The “non-interacting rigid arch model" used is based on the description of static configurations ...
Packing triangles in low degree graphs and indifference graphs
(ELSEVIER SCIENCE BV, 2008)
We consider the problems of finding the maximum number of vertex-disjoint triangles (VTP) and edge-disjoint triangles (ETP) in a simple graph. Both problems are NP-hard. The algorithm with the best approximation ratio known ...
Characterization of packed-bed in the downcomer of a concentric internal-loop airlift bioreactor
(2022-04-01)
A packed-bed basket containing corn cob powder was used for the adaptation of a concentric-tube airlift reactor for enzymatic reactions. The bed was inserted in the downcomer region of the bioreactor generating a decrease ...

Lattices from subfields of Q (xi n)
(Institute of Electrical and Electronics Engineers (IEEE), 2006-01-01)
In this paper we present a method for evaluating the center density of algebraic lattices from subfields of Q(xi n), where n is a positive integer. This method allows to reproduce rotated versions of dense lattices in some ...
Line-pack management for producing electric power on peak periods
(Pergamon-Elsevier B.V. Ltd, 2011-01-01)
The distribution of natural gas is carried out by means of long ducts and intermediate compression stations to compensate the pressure drops due to friction. The natural gas compressors are usually driven by an electric ...
