A novel algebraic method for the simultaneous estimation of MIMO channel parameters from channel sounder measurements is developed. We consider a parametric multipath propagation model with P discrete paths where each path is characterized by its complex path gain, its directions of arrival and departure, time delay, and Doppler shift. This problem is treated as a special case of the multidimen...

Work on comparing a set of linguistic test scores for MT output to a set of the same tests’ scores for naturally-occurring target language text (Jones and Rusk 2000) broke new ground in automating MT Evaluation. However, the tests used were selected on an ad hoc basis. In this paper, we report on work to extend our understanding, through refinement and validation, of suitable linguistic tests i...

Diseases of the gall-bladder such as cholecystitis or cholelithiasis are considered to be rare in childhood. In a hospital series of gall-stone cases, Linnemann (1938) found one child as against 3,600 adults. Since then improvements in the methods of investigation and in the diagnostic aids have made earlier diagnosis of gall-stone disease possible. Arnspiger, Martin and Krempin (1960) observed...
