Multicriteria analysis for sources of renewable energy using data from remote sensing [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Renewable energy sources are major components of the strategy to reduce harmful emissions and to replace depleting fossil energy resources. Data from remote sensing can provide information for multicriteria analysis for sources of renewable energy ...

Scaling‐down biopharmaceutical production processes via a single multi‐compartment bioreactor (SMCB)
Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract Biopharmaceutical production processes often use mammalian cells in bioreactors larger than 10,000 L, where gradients of shear stress, substrate, dissolved oxygen and carbon dioxide, and pH are likely to occur. As former tissue cells, producer cell lines such as Chinese hamster ovary (CHO) cells sensitively respond to these mixing ...

International Journal of Applied Mathematics and Computer Science, 2021 The paper proposes an algorithm for safeness verification of a Petri net-based specification of the control part of cyber-physical systems. The method involves a linear algebra technique and is based on the computation of the state machine cover of a ...

Spatio-temporal evaluation of ecosystem services in the São Paulo Macrometropolis, Brazil
Revista Brasileira de Ciências Ambientais, 2023 Urbanization is one of the key factors that drive changes in ecosystem services. Although various studies have analyzed relationships between land-cover change and ecosystem services degradation, few have explored the impacts in future scenarios in mega ...

Very well-covered graphs via the Rees algebra [PDF]
arXiv, 2023 A very well-covered graph is a well-covered graph without isolated vertices such that the size of its minimal vertex covers is half of the number of vertices. If $G$ is a Cohen-Macaulay very well-covered graph, we deeply investigate some algebraic properties of the cover ideal of $G$ via the Rees algebra associated to the ideal.

Exel's crossed product for non-unital C*-algebras [PDF]
, 2009 We consider a family of dynamical systems (A,alpha,L) in which alpha is an endomorphism of a C*-algebra A and L is a transfer operator for \alpha. We extend Exel's construction of a crossed product to cover non-unital algebras A, and show that the C ...

Skeletons of Prym varieties and Brill--Noether theory
, 2021 We show that the non-Archimedean skeleton of the Prym variety associated to an unramified double cover of an algebraic curve is naturally isomorphic (as a principally polarized tropical abelian variety) to the tropical Prym variety of the associated ...

Vector spaces as unions of proper subspaces [PDF]
, 2009 In this note, we find a sharp bound for the minimal number (or in general, indexing set) of subspaces of a fixed (finite) codimension needed to cover any vector space V over any field.
