A Note on Square Extensions of Bands
The construction of (associative) square extension of an idempotent groupoid (semigroup) was recently introduced by A. W. Marczak and J. PÃlonka. They proved that all square extensions of a variety of idempotent groupoids also form a variety. In this note we explicitely describe the free objects in semigroup varieties obtained from band varieties by means of associative square extensions, which...

متن کاملDirect measurement of additional Ar–H2O vibration–rotation-tunneling bands in the millimeter–submillimeter range
Three new weak bands of the Ar–H2O vibration–rotation-tunneling spectrum have been measured in the millimeter wavelength range. These bands were predicted from combination differences based on previously measured bands in the submillimeter region. Two previously reported submillimeter bands were also remeasured with higher frequency resolution. These new measurements allow us to obtain accurate...
متن کاملConstrained least square design of FIR filters without specified transition bands
We consider the design of digital lters and discuss the inclusion of explicitly speciied transition bands in the frequency domain design of FIR lters. We put forth the notion that explicitly speciied transition bands have been introduced in the lter design literature as an indirect and often inadequate approach for dealing with discontinuities in the desired frequency response. We also present ...
