The Reverse Social Distance Scale

The Journal of Social Psychology, 1996
A "reverse" Social Distance Scale was created by modifying Bogardus's Social Distance Scale, to measure minority groups' perceptions of the social distance established by the majority group between itself and minority groups. The Reverse Social Distance Scale (Guttman's coefficient of reproducibility = 0.99) differentiated between the African American ...

The Cepheid distance scale

Publications of the Astronomical Society of the Pacific, 1991
Developments concerning the period-luminosity (PL) relation for classical Cepheids are discussed with particular emphasis on the fact that Cepheids continue to provide the most homogeneous and reliable set of distances to many nearby galaxies. Observational programs relating to extragalactic Cepheids are also reviewed, and new distances and reddenings ...

Distance Scale from Supernovae

1999
Supernovae have been playing an ever increasing role in the determination of the key cosmological parameters. They are extremely luminous point sources whose brightness at maximum rivals that of their host galaxies and thus can be observed at cosmologically significant distances.

Size–Distance Scaling With Absolute and Relative Auditory Distance Information

Multisensory Research, 2020
Abstract In the dynamic 3D space, it is critical for survival to perceive size of an object and rescale it with distance from an observer. Humans can perceive distance via not only vision but also audition, which plays an important role in the localization of objects, especially in visually ambiguous environments.

Galactic Distance Scales

1987
The distance scales for a number of young and old objects of Galactic importance are discussed and are compared through the value of Ro, the distance to the Galactic Centre which these scales imply. Reasonably consistent values of Ro can be obtained and in the mean Ro = 7 kpc. A realistic standard error for Ro is probably about 0.8 kpc.

The extragalactic distance scale

Space Science Reviews, 1988
Developments in the extragalactic distance scale during the period 1983–1987 are reviewed. There have been many very significant improvements in our knowledge of the distance scale during this period, yet the overall shift in the distance scale from that adopted in Cosmological Distance Ladder (Rowan-Robinson, 1985, CDL) is small.

The cosmic distance scale

The Astronomy and Astrophysics Review, 1989
The status of the cosmic distance scale problem in early 1989 is reviewed. Internally consistent distances to Local Group galaxies are given in Tables 5 and 6. Within the Local Group the distance scale is found to be 11±5% smaller than that previously adopted by Sandage and Tammann.

Multi-Scale Salience Distance Transforms

Procedings of the British Machine Vision Conference 1993, 1993
The distance transform has been proposed for use in computer vision for a number of applications such as matching and skeletonisation. This paper proposes two things: (1) a multi-scale distance transform to overcome the need to choose edge thresholds and scale and (2) the addition of various saliency factors such as edge strength, length and curvature ...
