Parametric Connotation and Theoretical Extension of Parametric Architecture Aesthetics [PDF]

open access: yesScience Innovation, 2017
Parametric Design has aroused the innovation in the architectural form creation, space conception and technology conception as a sort of new thinking mode. Coming along with this situation, architectural aesthetics has already started a new step in the influence of parametric design.

Rate-dependent extensions of the parametric magneto-dynamic model with magnetic hysteresis

open access: yesAIP Advances, 2017
This paper extends the parametric magneto-dynamic model of soft magnetic steel sheets to account for the phase shift between local magnetic flux density and magnetic field strength.

Brief communication: An elliptical parameterisation of the wind direction rose [PDF]

open access: yesWind Energy Science
This brief communication presents a parametric model for the wind direction rose, based on ellipse geometry. Such a model supports standardisation and identification of generally representative cases, while also enabling systematic analyses of wind rose “

Recent developments in empirical dynamic modelling

open access: yesMethods in Ecology and Evolution, 2023
Ecosystems are complex and sparsely observed making inference and prediction challenging. Empirical dynamic modelling (EDM) circumvents the need for a parametric model and complete observations of all system variables.

A survey of popular R packages for cluster analysis [PDF]

open access: yes, 2016
Cluster analysis is a set of statistical methods for discovering new group/class structure when exploring datasets. This article reviews the following popular libraries/commands in the R software language for applying different types of cluster analysis:

L2-Boundedness of Marcinkiewicz Integrals along Surfaces with Variable Kernels: Another Sufficient Condition

open access: yesJournal of Inequalities and Applications, 2007
We give the L2 estimates for the Marcinkiewicz integral with rough variable kernels associated to surfaces. More precisely, we give some other sufficient conditions which are different from the conditions known before to warrant that the L2-boundedness ...

Boundedness of Generalized Parametric Marcinkiewicz Integrals Associated to Surfaces

open access: yesMathematics, 2019
In this article, the boundedness of the generalized parametric Marcinkiewicz integral operators M Ω , ϕ , h , ρ ( r ) is considered. Under the condition that Ω is a function in L q ( S n - 1 ) with q &

Foundations for structured programming with GADTs [PDF]

open access: yes, 2008
GADTs are at the cutting edge of functional programming and become more widely used every day. Nevertheless, the semantic foundations underlying GADTs are not well understood.

Parametric Linear Dynamic Logic [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We introduce Parametric Linear Dynamic Logic (PLDL), which extends Linear Dynamic Logic (LDL) by temporal operators equipped with parameters that bound their scope.

Geoadditive hazard regression for interval censored survival times [PDF]

open access: yes, 2005
The Cox proportional hazards model is the most commonly used method when analyzing the impact of covariates on continuous survival times. In its classical form, the Cox model was introduced in the setting of right-censored observations.
