On the embedding problem for 2+s4 representations
(American Mathematical Society, 2007-12)
Let 2+S4 denote the double cover of S4 corresponding to the element in H2(S4, Z/2Z) where transpositions lift to elements of order 2 and the product of two disjoint transpositions to elements of order 4. Given an elliptic ...
Representations of young people associated with crime in El Salvador's written press
(Taylor & Francis, 2007-04)
The paper attempts to uncover the interpretive models underlying the construction of social representations about the identity of young people associated with crime by El Salvador's written press. To achieve this goal, I ...
Time drawings: Spatial representation of temporal concepts
(Academic Press Inc Elsevier Science, 2018-03)
Time representation is a fundamental property of human cognition. Ample evidence shows that time (and numbers) are represented in space. However, how the conceptual mapping varies across individuals, scales, and temporal ...
On the representation dimension of some classes of algebras
(Academic Press Inc Elsevier Science, 2004-05)
We show that the representation dimension of the following classes of algebras is at most 3: (a) Artin algebras A such that the functor HomA (D(A), -) has finite length (or dually, HomA (-, A) has finite length). These ...

Chirality in a quaternionic representation of the genetic code
(Elsevier, 2016-12)
A quaternionic representation of the genetic code, previously reported by the authors (BioSystems 141(10?19), 2016), is updated in order to incorporate chirality of nucleotide bases and amino acids. Theoriginal representation ...
Computing sparse representations of multidimensional signals using Kronecker bases
(M I T Press, 2013-01)
Recently, there is a great interest in sparse representations of signals under the assumption that signals (datasets) can be well approximated by a linear combination of few elements of a known basis (dictionary). Many ...
A proposal of quantum data representation to improve the discrimination power
(Springer, 2019-02-25)
This work proposes a quantum representation for improvement of data discrimination power, transforming a non linearly separable problem into a linearly separable problem. This methodology proposed here can be naturally ...
Knowledge representation in Industry 4.0 Scheduling problems
(Taylor & Francis Ltd, 2022-01-10)
Industry 4.0 raises the need for a closer integration of management systems in manufacturing companies. Such process is driven by Cyber-Physical Systems (CPS) and the Internet of Things (IoT). Starting from the potential ...
