The Determinants of Brazilian Football Clubs’ Debt Ratios by Marke Geisy da Silva Dantas, Raimundo Marciano de Freitas Neto, Maria Alice Alves da Costa, Alexandro Barbosa

“…The model employed was Generalized Estimating Equation. Our results suggest that debt ratios are more associated with their popularity or their participation in the highest division of its main championship rather than titles held, access to different competitions or relegation to lower levels. …”

Similarities and differences between exosystem-model-based disturbance observer and model error compensator by Kana Shikada, Noboru Sebe

“…Ohnishi et al. proposed to cancel out the effect of uncertainties with its estimated disturbance. Furthermore, in 2013, Okajima et al. proposed the model error compensator, which compensates for the error between the output of the nominal plant model and the measurement outputs of the actual plant. …”

Synthesis and characterization of tenorite (CuO) nanoparticles from smelting furnace dust(SFD) by Darezereshki E., Bakhtiari F.

“…The average diameter of the spherical pure CuO nanoparticles and their crystallite size were estimated to be 92 nm and 40nm, respectively. The simplicity of the present method suggests its potential application at industrial scale as a cheap and convenient way to produce pure CuO nanoparticles from dilute CuSO4 solutions obtained from leaching of smelting furnace dust.…”

A Family of Modified Even Order Bernoulli-Type Multiquadric Quasi-Interpolants with Any Degree Polynomial Reproduction Property by Ruifeng Wu, Huilai Li, Tieru Wu

“…By using the polynomial expansion in the even order Bernoulli polynomials and using the linear combinations of the shifts of the function f(x)(x∈ℝ) to approximate the derivatives of f(x), we propose a family of modified even order Bernoulli-type multiquadric quasi-interpolants which do not require the derivatives of the function approximated at each node and can satisfy any degree polynomial reproduction property. Error estimate indicates that our operators could provide the desired precision by choosing a suitable shape-preserving parameter c and a nonnegative integer m. …”

Approximation properties relative to continuous scale space for hybrid discretisations of Gaussian derivative operators by Tony Lindeberg

“…We characterise the properties of these hybrid discretisation methods in terms of quantitative performance measures, concerning the amount of spatial smoothing that they imply, as well as the relative consistency of the scale estimates obtained from scale-invariant feature detectors with automatic scale selection, with an emphasis on the behaviour for very small values of the scale parameter, which may differ significantly from corresponding results obtained from the fully continuous scale-space theory, as well as between different types of discretisation methods. …”

Traffic-Aware Data Delivery Scheme for Urban Vehicular Sensor Networks by Chunmei Ma, Nianbo Liu

“…Moreover, in order to decrease the routing overhead brought by the traffic information gathering, we build a traffic condition prediction model to estimate the link quality. The simulation results show that our TADS outperforms existing works on packet delivery ratio, end-to-end delay, and routing overhead.…”
