A great challenge in electro-Fenton processes is the development of active heterogeneous catalysts at circumneutral or even basic pH order to avoid acidification wastewater effluents and generation an undesirable metallic sludge after treatment. In this work, LaCu0.5Mn0.5O3 perovskite has been assessed as catalyst for removal methylene blue dye model pollutant. The tested a wide range pH, from ...

The number, variety and complexity of projects involving data mining or knowledge discovery in databases activities have increased just lately at such a pace that aspects related to their development process need to be standardized for results to be integrated, reused and interchanged in the future. Data mining projects are quickly becoming engineering projects, and current standard processes, ...

In this article, we describe two software design patterns that can be reused in the design of object-oriented geographical information systems (GIS). The first of them, called Spatial Object, captures the common structure and dynamics of the spatial entities represented in a GIS. The second one, called Spatial Graph, provides a solution to REVISTA COLOMBIANA DE COMPUTACIÓN Volumen 1, número 1 P...

In order to enable the single-pass design methodology, the planning of power distribution should be performed as early as possible. In this paper, we will tackle this problem at the floorplan stage. First, at the block level, we will present an effective method to model the behavior of local power network structure of a reused block. Next, at the full-chip level, we will present a floorplan-bas...
