Journal of Control Science and Engineering, 2016 High voltage gain power converters are very important in photovoltaic applications mainly due to the low output voltage of photovoltaic arrays. This kind of power converters includes three or more semiconductor devices and four or more energy storage ...

Global Ecology and Biogeography, Volume 31, Issue 10, Page 1906-1922, October 2022., 2022 Abstract Background ‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous. Approach We sought to resolve ambiguity surrounding the meaning of ‘megafire’ by conducting a structured review of the use and definition of the term in several ...

International Journal of Chemical Engineering, Volume 2018, Issue 1, 2018., 2018 The modulation in the synthesis parameters of layered manganese oxides allowed us to produce materials with different AC conductivities. These conductivities were correlated with the catalytic performance of the materials in the decomposition of methylene blue, as a model of electron transfer reactions.

Computing and Controlling Basins of Attraction in Multistability Scenarios
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 The aim of this paper is to describe and prove a new method to compute and control the basins of attraction in multistability scenarios and guarantee monostability condition. In particular, the basins of attraction are computed only using a submap, and the coexistence of periodic solutions is controlled through fixed‐point inducting control technique ...
