متن کاملThe Membership Problem for 〈 a , b : bab 2 = ab 〉
Throughout, P is the semigroup presentation 〈a, b: bab = ab〉 for the semigroup S1. Lallement and Rosaz, [5], have shown that the semigroups Sk having presentations 〈a, b: b(ab)b = ab〉 are residually finite. They also find normal forms for elements of Sk . Specialized to k = 1, every element of S1 is either a power of a or else it can be represented uniquely by a word in one of the forms aba or ...
متن کاملStratification and Double-Diffusive Convection in the Bab-el-Mandeb Strait during Winter Monsoon
Investigation of stratification in marine environments is always considered by researchers. In this study double-diffusive convection and stratification in the Bab el Mandeb strait is investigated by analyzing of field data. Measurement of seawater temperature and salinity from ARGO project (2009 to2014) and also R-V Knorr (2001) cruise with the daily average of seawater temperature and salinit...
متن کاملImpact of BaB 2 O 4 growth method on frequency conversion to the deep ultra-violet
In this article, we report how the growth method used for barium beta-borate β−BaB2O4 (BBO) impacts its high power second harmonic generation properties in the deep-UV. We compared a BBO crystal grown by flux (Top Seeded Solution Growth or TSSG) and a BBO crystal grown by the Czochralski (CZ) method. We first characterized their transparency properties, then we measured their single-pass second...
متن کاملComparison of A-block polydispersity effects on BAB triblock and AB diblock copolymer melts.
Recent experiments on triblock copolymer melts suggest that polydispersity effects are dramatically enhanced when polydisperse blocks are constrained by both ends to the internal interfaces of an ordered morphology. To quantify the relevance of architecture, we compare BAB triblock and AB diblock copolymer melts with polydisperse A blocks and monodisperse B blocks, using self-consistent field t...
