EVALUATION INDICATORS IN DISTANCE EDUCATION AT THE UNIVERSITY SYSTEM
RIED: Revista Iberoamericana de Educación a Distancia, 2001 The key- question the article propose is if it is possible to stablish a unique quality indicators system for all the universities. We realize there is no a consensus about which are the objectives at the University level.

Asymptotic Giant Branch Variables as Extragalactic Distance Indicators [PDF]
, 2012 Large-amplitude asymptotic giant branch variables potentially rival Cepheid variables as fundamental calibrators of the distance scale, particularly if observations are made in the infrared, or where there is substantial interstellar obscuration.

Comparing Primary Distance Indicators
Scholarly Review Journal, 2022 Measuring distances to astronomical objects is crucial for collecting and analyzing their properties. Different distance methods form the distance ladder, in which methods for shorter distances calibrate methods for larger distances. Parallax, main sequence fitting, variable stars, and red clump stars form the lower portion of the distance ladder ...

Process of ranking countries by level of development
Croatian Review of Economic, Business and Social Statistics, 2018 The paper presents the process of ranking and classifying countries using the I-distance method. The I-distance method is a method of classification and multidimensional ranking based on the distance values between selected indicators.

THE EDGE OF THE MILKY WAY STELLAR DISK REVEALED USING CLUMP GIANT STARS AS DISTANCE INDICATORS [PDF]
, 2011 We use the clump giants of the disk as standard candles calibrated from Hipparcos parallaxes in order to map their distribution with two new near-infrared surveys of the Galactic plane: UKIDSS-GPS and VISTA Variables in the Vía Láctea (VVV).

Ultra Luminous X-ray sources - new distance indicators? [PDF]
, 2018 In this paper we fit the NuSTAR and XMM-Newton data of three sources: NGC7793~P13, NGC5907~ULX1, and Circinus~ULX5. Our single model contains emission form non-spherical system: neutron star plus accretion disk directed towards observer.

Constraints on cosmological models and reconstructing the acceleration history of the Universe with gamma-ray burst distance indicators [PDF]
, 2009 Gamma-ray bursts (GRBs) have been regarded as standard candles at very high redshift for cosmology research. We have proposed a new method to calibrate GRB distance indicators with Type Ia supernova (SNe Ia) data in a completely cosmology-independent way

The Large Magellanic Cloud and the Distance Scale
, 2011 The Magellanic Clouds, especially the Large Magellanic Cloud, are places where multiple distance indicators can be compared with each other in a straight-forward manner at considerable precision.
