While there has been much research on the study of global virtual teams and global software teams, there has been practically no research on the nuances of time separation. We present three converging perspectives on this topic: (1) a view from practices and tactics of global teams; (2) a theoretical view from coordination theories; and (3) a view from our prior research in which we modeled coo...

We address the problem of Speech Enhancement in a setting where parts of the time-frequency content of the speech signal are missing. In telephony, speech is band-limited and the goal is to reconstruct a wide-band version of the observed data. Quite differently, in Blind Source Separation scenarios, information about a source can be masked by noise or other sources. These masked components are ...

Correlations between sequence separation (in residues) and distance (in Angstrom) of any pair of amino acids in polypeptide chains are investigated. For each sequence separation we define a distance threshold. For pairs of amino acids where the distance between C alpha atoms is smaller than the threshold, a characteristic sequence (logo) motif, is found. The motifs change as the sequence separa...

The problem of identifying disturbance lines in printed circuit boards is addressed. Identification is achieved by estimating the disturbance frequency and the separation distance between the coupled lines. Frequency estimation uses a wavelet coefficients thresholding method to reconstruct the interference caused by the disturbance line. The separation distance is computed using two empirical l...

The radiometric force produced by a linear array of three radiometer vanes has been assessed numerically using an argon carrier gas and experimentally using air. The separation distance between the three vanes of the array was varied between 0 and 120 percent based on the height of an individual radiometer vane of 40mm. Qualitative agreement between the numerical and experimental results is sho...

Abstract Approximately one billion people across the globe are living in informal settlements with a large potential fire risk. Due to high dwelling density, single settlement may result very serious disaster leaving thousands of homeless. In this work, simple physics-based theoretical model was employed assess critical separation distance between dwellings. The heat flux and ejected flame leng...

In air traffic management, the aircraft separation requirement is defined by a minimum horizontal distance and a minimum vertical distance that the aircraft have to maintain. Since this requirement defines a cylinder around each aircraft rather than a sphere, the three-dimensional Euclidean distance does not provide an appropriate basis for the definition of time of closest approach. For instan...

A fast algorithm is presented for computing the growth distance between a pair of convex objects in three-dimensional space. The growth distance is a measure of both separation and penetration between objects. When the objects are polytopes represented by their faces, the growth distance is determined by the solution of a Linear Program (LP). This article presents a new approach to the solution...
