In 1992 neurophysiologists [20] found a new type of cells in areas V1 and V2 of the monkey primary visual cortex, which they called grating cells. These cells respond vigorously to a grating pattern of appropriate orientation and periodicity. Three years later a computational model inspired by these findings was published [9]. The study of this paper is to create a grating cell operator that ha...

Parametric modeling is a statistical technique whereby a dependent variable is estimated based on the values of and the relationships between the independent variable(s). The nature of the dependent variable can vary greatly based on one’s domain of interest. In software engineering, parametric models are often used to help predict a system’s development schedule, cost-to-build, and quality at ...

Received: March 18, 2015; Accepted: March 20, 2015; Published: March 22, 2015 If you read these pages, you certainly know the seminal book by Benoit B. Mandelbrot, The Fractal Geometry of Nature (1982). In his Masterpiece, Benoit provides both a mathematical model and a description for many of the seemingly complex forms and patterns in nature, showing that fractal patterns are extremely famili...

How to prepare deterministically non-Gaussian entangled states is a fundamental question for continuous-variable quantum information technology. Here, we theoretically demonstrate through numerical methods that the triple-photon state generated by three-photon spontaneous parametric down-conversion pure super-Gaussian resource of entanglement. Interestingly, degree entanglement between modes st...

BACKGROUND Management pain in hospitalized children is challenging for the health-care professionals. Nurses have the most interactions with children who need to assess and manage for their pain. Therefore, the aim was to describe nurses' experiences from pain management among hospitalized children from Iranian culture in this study. METHODS A phenomenological study was conducted in which 23 ...

This paper is the third and final one in a sequence of three. All three papers emphasize that a proposition can be justified by an infinite regress, on condition that epistemic justification is interpreted probabilistically. The first two papers showed this for one-dimensional chains and for one-dimensional loops of propositions, each proposition being justified probabilistically by its precurs...

Nonparametric and parametric approaches have been proposed to estimate false discovery rate under the independent hypothesis testing assumption. The parametric approach has been shown to have better performance than the nonparametric approaches. In this article, we study the nonparametric approaches and quantify the underlying relations between parametric and nonparametric approaches. Our study...

Most of ex-ante impact assessment policy models have been based on a parametric approach. We develop a novel non-parametric approach, called Inverse DEA. We use non parametric efficiency analysis for determining the farm’s technology and behaviour. Then, we compare the parametric approach and the Inverse DEA models to a known data generating process. We use a bio-economic model as a data genera...

The article presented a mathematical analysis of double-circuit parametric circuit ferroresonance nature at the fundamental frequency, performed by harmonic balance method. adjustment, current-voltage, and load characteristics are given. possibility using this in voltage regulators with direct current output is proved. Parametric sources secondary power supply, particular stabilizers ferromagne...

Data Envelopment Analysis (DEA) is a technique used to compare efficiency in various sectors such as hospitals, chain stores, and dealerships. It represents a set of linear programming techniques and uses deter-ministic data (inputs and outputs), in stable conditions. The DEA technique cannot be used when there is data with indeterministic nature, or when there is an environment with dynamic co...
