Feature detection using relative distance and multi-scale technique

Alexandria Engineering Journal, 2022
Corner is an import type of feature point of image and has been widely used in image analysis and vision tasks. To enhance the robustness to contour noise and geometrical transformations and meanwhile improve the localization accuracy, we develop a novel

Determining Evolution of Cosmological Constant, Gravitational Constant and Speed of Light Using Nonadiabatic Cosmological Model and LLR Findings

Galaxies, 2019
We have shown that the Hubble constant H 0 embodies the information about the evolutionary nature of the cosmological constant Λ , gravitational constant G , and the speed of light c .

Allan Sandage and the distance scale [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractAllan Sandage returned to the distance scale and the calibration of the Hubble constant again and again during his active life, experimenting with different distance indicators. In 1952 his proof of the high luminosity of Cepheids confirmed Baade's revision of the distance scale (H0 ~ 250 km s−1 Mpc−1).

The distance scale of planetary nebulae [PDF]

Astronomy & Astrophysics, 2001
By collecting distances from the literature, a set of 73 planetary nebulae with mean distances of high accuracy is derived. This sample is used for recalibration of the mass-radius relationship, used by many statistical distance methods. An attempt to correct for a statistical peculiarity, where errors in the distances influences the mass--radius ...

Exploring Preferences for a Digital Single‐Session Intervention for Adolescent Siblings of Youth With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

SCALES FOR SUBJECTIVE DISTANCE

Scandinavian Journal of Psychology, 1960
By means of the method of ratio estimation, scale values were obtained for subjective distance. In three experiments different stimulus ranges of the objective distances were used. It was found: (1) Subjective distance is a power function of the objective distance. (2) The exponent of the function varies with the stimulus range.

Astronomical distance scales

Comptes Rendus. Physique, 2019
This article is an overview of the determination of astronomical distances from a metrological standpoint. Distances are considered from the Solar System (planetary distances) to extragalactic distances, with a special emphasis on the fundamental step of the trigonometric stellar distances and the giant leap recently experienced in this field thanks to

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Employee Silence Predicted by Abusive Leadership and Workplace Ostracism: Role of Employee Power Distance

International Journal of Educational Leadership and Management, 2023
The proposed research aimed to examine abusive leadership and workplace ostracism as predictors of employee silence among school teachers in Sargodha, Pakistan. Studies further tend to examine the moderating role of power distance.

A ratio scale for social distance

Journal of the Experimental Analysis of Behavior, 2020
Choosing a larger–later reward over a smaller–sooner reward may be thought of as altruism toward one's future self. A question that arises in this connection is: What is the relation between delay and social discounting? To begin to answer this question, social and delay discount functions need to be comparable.
