Distance Critical Graphs [PDF]
Graphs and CombinatoricsAbstract In 1971, Graham and Pollak provided a formula for the determinant of the distance matrix of any tree on n vertices. Yan and Yeh reproved this by exploiting the fact that pendant vertices can be deleted from trees without changing the remaining entries of the distance matrix.

Sparse Distributed Memory: understanding the speed and robustness of expert memory
Frontiers in Human Neuroscience, 2014 How can experts, sometimes in exacting detail, almost immediately and very precisely recall memory items from a vast repertoire? The problem in which we will be interested concerns models of theoretical neuroscience that could explain the speed and ...

Critical Issues in Open and Distance Education Research
International Review of Research in Open and Distributed Learning, 2023 Despite its mainstreaming into the broader educational ecology, open and distance education (ODE) still leaves much to be desired in terms of both practice and research. Inspired and informed by the author’s 35 years of experience as an ODE practitioner,

Metals, 2018 The structural integrity assessment of components containing notch-type defects has been the subject of extensive research in the last few decades. The assumption that notches behave as cracks is generally too conservative, making it necessary to develop

Reverberation Radius in Real Rooms [PDF]
Telfor Journal, 2010 A reverberation radius, also called a critical distance, is an important parameter in sound reproduction. Statistical approach gives a simple formula for its calculation, and some simple methods for its measurement were described in literature.
