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

Wind 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 “

How robust are particle physics predictions in asymptotic safety?

European Physical Journal C: Particles and Fields, 2023
The framework of trans-Planckian asymptotic safety has been shown to generate phenomenological predictions in the Standard Model and in some of its simple new physics extensions.

Parametricity for Nested Types and GADTs [PDF]

Logical Methods in Computer Science, 2021
This paper considers parametricity and its consequent free theorems for nested data types. Rather than representing nested types via their Church encodings in a higher-kinded or dependently typed extension of System F, we adopt a functional programming ...

Strict extensions in pointfree topology [PDF]

, 2013
Extensions of spaces have been constructed and used since the 19th century, for example, to form the complex sphere from the complex plane by adding a point at in nity.

Boundedness of Generalized Parametric Marcinkiewicz Integrals Associated to Surfaces

Mathematics, 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 &

Recent developments in empirical dynamic modelling

Methods 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.

Products of parametric extensions: refined estimates

Journal of Numerical Analysis and Approximation Theory
We present point wise estimates on approximation by bounded linear operators of real-valued continuous functions defined on the cartesian product of d compact intervals. The main purpose is to provide a unified theory to deal with pointwise estimates on

Parametric and nonparametric inference in equilibrium job search models [PDF]

, 2008
Equilibrium job search models allow for labor markets with homogeneous workers and firms to yield nondegenerate wage densities. However, the resulting wage densities do not accord well with empirical regularities.

Parametric Linear Dynamic Logic [PDF]

Electronic 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.

A Review on Variable Selection in Regression Analysis

Econometrics, 2018
In this paper, we investigate several variable selection procedures to give an overview of the existing literature for practitioners. “Let the data speak for themselves„ has become the motto of many applied researchers since the number of ...
