Natureinspired approaches for distance metric learning in multivariate time series classification
(IEEE Congress on Evolutionary Computation, 2017)The applicability of time series data mining in many different fields has motivated the scientific community to focus on the development of new methods towards improving the performance of the classifiers over this particular ... 
Multiobjective heuristics applied to robot task planning for inspection plants
(IEEE Congress on Evolutionary Computation, 2017)Robotics are generally subject to stringent operational conditions that impose a high degree of criticality on the allocation of resources and the schedule of operations in mission planning. In this regard the socalled ... 
Natureinspired heuristics for the multiplevehicle selective pickup and delivery problem under maximum profit and incentive fairness criteria
(IEEE Congress on Evolutionary Computation, 2017)This work focuses on widescale freight transportation logistics motivated by the sharp increase of online shopping stores and the upsurge of Internet as the most frequently utilized selling channel during the last decade. ... 
A local search method for graph clustering heuristics based on partitional distribution learning
(IEEE Congress on Evolutionary Computation, 2017)The community structure of complex networks reveals hidden relationships in the organization of their constituent nodes. Indeed, many practical problems stemming from different fields of knowledge such as Biology, Sociology, ... 
KETpicMatlab Toolbox for LaTeX HighQuality Graphical Artwork in Educational Materials on Bézier Curve Algorithms at a Master Level
(Lecture Notes in Computer Science, 201707)This paper introduces a new toolbox to generate highquality graphical artwork about the main algorithms for Bézier curves and related topics. The package has been implemented by the authors as a supporting middleware tool ... 
Monotonicity and convexity of the ratios of the first kind modified Bessel functions and applications
(Mathematical Inequalities & Applications, 20170718)Let $I_{v}\left( x\right) $ be modified Bessel functions of the first kind. We prove the monotonicity property of the function $x\mapsto I_{u}\left( x\right) I_{v}\left( x\right) /I_{\left( u+v\right) /2}\left( x\right) ... 
HartreeFock theory with a selfgenerated magnetic field
(Journal of Mathematical Physics, 20170601)We prove the existence of a ground state within the HartreeFock theory for atoms and molecules, in the presence of selfgenerated magnetic fields, with and without direct spin coupling. The ground state exists provided ... 
A simple Bayesian linear excess relative risk model
(20170711)A new Bayesian Poisson relative risk model is proposed for displaying the excess relative risk associated to a unique exposure as a probability distribution in a closed form. The background risk can be modelled by a unique ... 
Towards HPCEmbedded Case Study: Kalray and MessagePassing on NoC
(Scalable Computing, 2017)Today one of the most important challenges in HPC is the development of computers with a low power consumption. In this context, recently, new embedded manycore systems have emerged. One of them is Kalray. Unlike other ... 
Detection of nontechnical losses in smart meter data based on load curve profiling and time series analysis
(Energy, 201706)The advent and progressive deployment of the socalled Smart Grid has unleashed a profitable portfolio of new possibilities for an efficient management of the lowvoltage distribution network supported by the introduction ... 
The weighted independent domination problem: ILP model and algorithmic approaches
(Lecture Notes in Computer Science, 20170601)This work deals with the socalled weighted independent domination problem, which is an N P hard combinatorial optimization problem in graphs. In contrast to previous theoretical work from the liter ature, this paper ... 
New Simplified Algorithm for the Multiple Rotating Frame Approach in Computational Fluid Dynamics
(Journal of Fluids Engineering, 20170602)This paper deals with rotating effects simulation of steady flows in turbomachinery. To take into account the rotating nature of the flow, the frozen rotor approach is one of the widely used approaches. This technique, ... 
Sharp bounds for the ratio of modified Bessel functions
(Mediterranean Journal of Mathematics, 20170621)Let $I_{\nu }\left( x\right) $ be the modified Bessel functions of the first kind of order $\nu $, and $S_{p,\nu }\left( x\right) =W_{\nu }\left( x\right) ^{2}2pW_{\nu }\left( x\right) x^{2}$ with $W_{\nu }\left( x\right) ... 
Lorentz estimates for asymptotically regular fully nonlinear parabolic equations

Numerical valuation of twoasset options under jump diffusion models using GaussHermite quadrature
(Journal of Computational and Applied Mathematics, 20170419)In this work a finite difference approach together with a bivariate Gauss–Hermite quadrature technique is developed for partial integrodifferential equations related to option pricing problems on two underlying asset ... 
From G  Equation to Michelson  Sivashinsky Equation in Turbulent Premixed Combustion Modelling
(Proceedings/Extended Abstract Book (6 pages) of the XXXIX Meeting of the Italian Section of the Combustion Institute, Naples, Italy, 20170620)It is well known that the MichelsonSivashinky equation describes hydrodynamic instabilities in turbulent premixed combustion. Here a formulation of the flame front propagation based on the Gequation and on stochastic ... 
DarrieusLandau instabilities in the framework of the Gequation
(Digital proceedings of the 8th European Combustion Meeting, 1821 April 2017, Dubrovnik, Croatia, 201704)We consider a model formulation of the flame front propagation in turbulent premixed combustion based on stochastic fluctuations imposed to the mean flame position. In particular, the mean flame motion is described by ...
