Evaluating a distance function
Comptes Rendus. Mécanique, 2023 Computing the distance function to some surface or line is a problem that occurs very frequently. There are several ways of computing a relevant approximation of this function, using for example technique originating from the approximation of Hamilton ...

The boolean map distance: theory and efficient computation [PDF]
, 2017 We propose a novel distance function, the boolean map distance (BMD), that defines the distance between two elements in an image based on the probability that they belong to different components after thresholding the image by a randomly selected ...

THE EULER NUMBER FROM THE DISTANCE FUNCTION
Image Analysis and Stereology, 2013 We present a new method to obtain the Euler number of a domain based on the tangent counts of concentric spheres in ℝ³ (or circles in ℝ², with respect to the center O, that sweeps the domain.

Effect of allopurinol on phosphocreatine recovery and muscle function in older people with impaired physical function:a randomised controlled trial [PDF]
, 2020 Background: Allopurinol has vascular antioxidant effects and participates in purinergic signalling within muscle. We tested whether allopurinol could improve skeletal muscle energetics and physical function in older people with impaired physical ...

A PARALLEL ARCHITECTURE FOR CURVE-EVOLUTION PARTIAL DIFFERENTIAL EQUATIONS
Image Analysis and Stereology, 2011 The computation of the distance function is a crucial and limiting element in many applications of image processing. This is particularly true for the PDE-based methods, where the distance is used to compute various geometric properties of the travelling

On the Distributional Hessian of the Distance Function [PDF]
, 2014 We describe the precise structure of the distributional Hessian of the distance function from a point of a Riemannian manifold. In doing this we also discuss some geometrical properties of the cutlocus of a point and we compare some different weak ...

A Linear Inverse Demand System
Journal of Agricultural and Resource Economics, 1992 We present an inverse demand that can be estimated in a linear form. The model is derived from a specification of the distance function which is parametrically similar to the cost function underlying the Almost Ideal Demand System.

Estimating a Profit Function in the Presence of Inefficiency: An Application to Russian Agriculture
Journal of Agricultural and Resource Economics, 2002 The relationship among cost functions, distance functions, and technical inefficiency are utilized to show how technical inefficiency scores can be incorporated into the specification of a profit function and a related system of output supply and input ...

Environmentally Adjusted Agricultural Productivity in the Great Plains
Journal of Agricultural and Resource Economics, 2004 This study adjusts 1960-1996 agricultural productivity gains in a panel of Great Plains states to account for the discharge of pesticide and nitrogen effluents into the environment.

Malmquist Index, an Alternative Technique for Measuring Credit Institutions Productivity [PDF]
Theoretical and Applied Economics, 2008 The present study tackles the banking system’s productivity in a more complex manner, that integrates multiple input, multiple output variables, abdicating from the reductionist perspective of clasical methods, which imposed limits in the number of ...
