(1965)-In the most direct method for measuring correlation functions with an analog computer a delay must be simulated. Since a lumped parameter system is used, we can only hope to approximate this delay. We intentionally exclude ...
-
(1975)The energy-momentum tensor of the field produced by an electron with arbitrary movement in a curved space contains a tensor Tμνr with the following properties: (i) vanishing covariant divergence, (ii) null flux across the ...
-
(Universidad de Chile, 1978)Geológicamente esta región se puede dividir en dos fajas dispuestas aproximadamente N-S; la oriental constituida por una serie de formaciones arenosas y arcillosas del Cretacico más alto, hasta la base del Maastrichtiano; ...

(1979)An algorithm for phylogenetic trees' construction is analyzed
-
(Universidad de Chile, 1980)El esquema de explotación actual en la Mina Chuquicamata fue determinado considerando que para el lastre se usaría palas de 15 ydf y camiones de 120 tc. Siguiendo la tendencia en la minería a cielo abierto de utilizar ...

(1981)We propose an indirect way to study some solutions of Yang-Mills equations, which is based on the analysis of the following closely related equations: F+A×F=0 and F»+A×F»=0. The former is one of the standard Yang-Mills ...

(1988-08-15)A complete CO survey of the central 6 deg x 6 deg of the LMC was performed in order to determine the distribution of molecular clouds. At least 10 percent of the region studied exhibits CO line emission, with peak line ...

(The American Astronomical Society, 1988-10-15)New 6 cm continuum and radio recombination line VLA observations as well as CO observations are presented of the bright PN NGC 6302. The H110-alpha line is significantly broader than the H76-alpha line, an effect which is ...

(The Astronomical journal, 97: 720-725, 1989, 1989-03)UVBRI photoelectric sequences for fifteen AGNs were obtained with 0.6, 0.9, and 1-m telescopes. The data include 473 observations for 118 stars, giving an average of 4.0 observations per star, and 7.9 stars per sequence. ...

(1989-03-01)The most powerful water maser feature ever seen in Orion was monitored for seven years. The maser reached a peak flux density of about 6.7 x 10 to the 6th Jy. The total radiated energy between August 1979 and June 1987 was ...
