Abstract The aim of the paper consists in study three Romanian types marble (Ruschita, Albesti, Carrara) with different compositions temperature conditions, for periods time. samples were exposed to two treatments: 25 cycles freeze-thaw (according SR EN 12371) and 3 exposure high temperatures (400 °C 1 hour). Following cycles, small differences chromatic parameters could be observed (∆E = 2.2 C...

Infection of BALB/3T3 cells by polyoma virus causes an alteration in the cell surface, characterized by enhanced agglutination of the cells by wheat germ agglutinin or concanavalin A. Infection by the thermosensitive mutant of polyoma, ts-3, causes the cell surface alteration at the permissive temperature, but not at the nonpermissive temperature. The cell surface alteration requires cellular D...

Wettability alteration has been a sophisticated issue for scientists and reservoir engineers since early 20th century; thus, many investigations have been carried out to determine wettability and enhance it to ideal conditions, which leads to improvement in oil recovery. Dilute surfactant flooding has been approved as one of the noteworthy methods in chemical flooding. Several petroleum reservo...

The state of a POMDP can often be factored into a tuple of n state variables. The corresponding flat model, with size exponential in n, may be intractably large. We present a novel method called conditionally irrelevant variable abstraction (CIVA) for losslessly compressing the factored model, which is then expanded into an exponentially smaller flat model in a representation compatible with ma...

This paper proposes a new blind sequence estimation method for single-input single-output (SISO) systems utilizing an optimal trellis search, which is performed by a channel-independent Viterbi algorithm (CIVA). In contrast to the traditional Viterbi algorithm that requires accurate channel estimation, CIVA does not require channel coefficients. Instead, the metrics are calculated from a bank o...
