Fibonacci Series from Power Series [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2020
We show how every power series gives rise to a Fibonacci series and a companion series involving Lucas numbers. For illustrative purposes, Fibonacci series arising from trigonometric functions, inverse trigonometric functions, the gamma function and the digamma function are derived.

Deep learning for time series classification: a review [PDF]

open access: yesData mining and knowledge discovery, 2018
Time Series Classification (TSC) is an important and challenging problem in data mining. With the increase of time series data availability, hundreds of TSC algorithms have been proposed.

INFLUENCIA DE LOS DATOS DISCORDANTES SOBRE LA MATRIZ DE CORRELACIÓN Y CORRELACIÓN PARCIAL EN UN CONJUNTO DE DATOS MULTIVARlADO

open access: yesPesquimat, 2014
Una parte importante de la utilidad del análisis de influencia es determinar la debilidad de algunos estimadores tradicionales frente a la presencia de datos discordantes tales como los Bj (coeficientesde regresión) y los ri (residuales) en un análisis ...

The Role of Low Temperature Waste Heat Recovery in Achieving 2050 Goals: A Policy Positioning Paper

open access: yesEnergies, 2020
Urban waste heat recovery, in which low temperature heat from urban sources is recovered for use in a district heat network, has a great deal of potential in helping to achieve 2050 climate goals.

Contracts, Business Models and Barriers to Investing in Low Temperature District Heating Projects

open access: yesApplied Sciences, 2019
Approximately 1.2 EJ of energy are potentially available for recovery each year from urban heat sources in the EU. This corresponds to more than 10 percent of the EU’s total energy demand for heat and hot water.

The empirical mode decomposition and the Hilbert spectrum for nonlinear and non-stationary time series analysis

open access: yesProceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998
A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the ‘empirical mode decomposition’ method with which any complicated data set can be decomposed into a finite and often small number of ...
