How Do We Create Experiences for Students That Connect with What They Care About?
(MDPI, 2018-10-26)
The main aim of this work is to describe the process by which some students, participating in a teaching experiment, recreate with guidance material and personal attendance some advanced concepts at the doctoral level. ...
Problem-Based Teaching through Video Podcasts for Coding and Cryptography
(MDPI, 2018-10-31)
In this work we present the development and preliminary evaluation of several problem-based video podcasts addressed to students of the subject “Coding and Cryptography”. Specifically, this experiment has been carried out ...
Sustainable Renewable Energy by Means of Using Residual Forest Biomass
(MDPI, 2018-12-21)
The substitution of energy based on fossil fuel by bioenergy could be an effective solution to reduce external energy dependency, thereby promoting sustainable development. This article details a study of the use of biomass ...
CALE: Learning by Example in Mathematics with Applets in Mathematical Computational Packages
(MDPI, 2018-10-28)
In this work we present a methodology of “learning by example” assisted by computers in the study of mathematics. We propose the use of mathematical computational packages to program applets aimed to solve mathematical ...
Binormal Motion of Curves with Constant Torsion in 3-Spaces
(Hindawi, 2017)
We study curve motion by the binormal flow with curvature and torsion depending velocity and sweeping out immersed surfaces. Using the Gauss-Codazzi equations, we obtain filaments evolving with constant torsion which arise ...
Orness For Idempotent Aggregation Functions
(MDPI, 2017-09-20)
Aggregation functions are mathematical operators that merge given data in order to obtain a global value that preserves the information given by the data as much as possible. In most practical applications, this value is ...
An extension of the fuzzy unit interval to a tensor product with completely distributive first factor
(Elsevier, 2018-07-10)
The original Hutton interval I (L) can algebraically be identified with the tensor product I ⊗ L of the real unit interval I and a complete lattice L. Due to this, the tensor product M ⊗ L with M a completely distributive ...
An isoperimetric-type inequality for electrostatic shell interactions for Dirac operators
(Springer Nature, 2015-10-17)
Abstract: In this article we investigate spectral properties of the coupling H +Vλ, where
H = −iα ·∇ +mβ is the free Dirac operator in R3 , m > 0 and Vλ is an electrostatic shell
potential (which depends on a parameter ...
Cohomology of p-groups of nilpotency class smaller than p
(De Gruyter, 2018-01-17)
Let p be a prime number, let d be an integer and let G be a d-generated finite p-group of nilpotency class smaller than p. Then the number of possible isomorphism types for the mod p cohomology algebra H^∗(G;F_p) is bounded ...
An efficient evolutionary algorithm for the orienteering problem
(Elsevier, 2017-09-06)
This paper deals with the Orienteering Problem, which is a routing problem. In the Orienteering
Problem each node has a profit assigned and the goal is to find the route that maximizes the total
collected profit subject ...
