Chirp-wave expansion of the electron wavefunctions in atoms
(2014)
The description of the electron wavefunctions in atoms is generalized to the fractional Fourier series. This method introduces a continuous and infinite number of chirp basis sets with linear variation of the frequency to ...
The notion of Kierkegaardian conscience as an implication of the outside world: A critique of the Cartesian approach
(Universidad del Norte, 2019)
This article aims at showing how the Danish philosopher SØren Kierkegaard, through his concept of conscience, criticizes Cartesian skepticism upon affirming the impossibility of doubting the outside world, since the very ...
A convex OPF approximation for selecting the best candidate nodes for optimal location of power sources on DC resistive networks
(Elsevier B.V., 2019)
This paper proposes a convex approximation approach for solving the optimal power flow (OPF) problem in direct current (DC) networks with constant power loads by using a sequential quadratic programming approach. A ...
The maximal subspace for generation of (a,k)-regularized families
(2012)
Let A be a linear operator in a Banach space X. We define a subspace of X and a norm such that the part of A in such subspace generates an (a, k)-regularized resolvent family. This space is maximal-unique in a suitable ...
Element Free Galerkin (EFG) sensitivity study in structural analysis
(Institute of Physics Publishing, 2019)
The present study shows a parametric analysis of the meshfree method, Element Free Galerkin (EFG), on the elastic analysis of a cantilever beam. This study allows us to determine the best convergence conditions of the ...
A submersible printed sensor based on a monopole-coupled split ring resonator for permittivity characterization
(MDPI AG, 2019)
This work presents a non-invasive, reusable and submersible permittivity sensor that uses a microwave technique for the dielectric characterization of liquid materials. The proposed device consists of a compact split ring ...
Inventory Management Methodology to determine the levels of integration and collaboration in supply chain
(Universidad de Tarapaca, 2017)
This paper presents a Methodology of Inventory Management that determines the levels of integration and cooperation in a supply chain, so that policies and joint actions to improve the performance of the actors in the chain ...
Study on high throughput nanomanufacturing of photopatternable nanofibers using tube nozzle electrospinning with multi-tubes and multi-nozzles
(Society of Micro and Nano Systems, 2017)
High throughput nanomanufacturing of photopatternable nanofibers and subsequent photopatterning is reported. For the production of high density nanofibers, the tube nozzle electrospinning (TNE) process has been used, where ...
Viscosity analysis in lubricants through factorial design with three factors
(Latin American and Caribbean Consortium of Engineering Institutions, 2018)
In the field of statistics, the experimental design becomes an analysis tool to establish the ideal conditions of a very important process and / or product, analysis of variance it is very useful in cases where there are ...
Volatile organic compounds in the atmosphere of Mexico City
(Elsevier Ltd, 2015)
The Mexico City Metropolitan Area (MCMA) is one of the most polluted megacities in North America. Therefore, it is an excellent benchmark city to understand atmospheric chemistry and to implement pilot countermeasures. Air ...
