The concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. The notion of free fuzzy modules was introducedby Muganda as an extension of free modules in the fuzzy context. Zahedi and Ameriintroduced the concept of projective and injective L-modules. In this paper we give analternate definition for projective L-modules. We prove that e...

ANTHEPROT is a fully interactive graphics program devoted to the analysis of the sequences and structures of proteins. This program, originally developed to facilitate the protein sequence analysis coupled with multiple alignments and predicted secondary structures of proteins, now comprises a powerful 3D module to display and handle macromolecular structures. All the methods that were previous...

In an era of discrete tube or transistor op-amp modules, any potential advantage to be gained from fully-differential circuitry was masked by primitive op-amp module performance. Fullydifferential output op-amps were abandoned in favor of single ended op-amps. Fully-differential op-amps were all but forgotten, even when IC technology was developed. The main reason appears to be the simplicity o...

Introduction: Education and learning systems are globally evolving toward self-learning-based educational models. The purpose of this study was to determine the features and principles of developing a self-learning module, compare the self-learning module with other methods of teaching, and explore the effects of self-learning module on learning. Methods: In this review study, data were collect...

February 2013 www.bodospower.com INTRODUCTION SiC is currently the only wide bandgap material to address the power electronics market needs for high performance 1200V and 1700V devices. SiC diode technology has thrived in the market for more than a decade, and many switches have recently become available to enable “all-SiC” circuit solutions. For example, in November 2012, Cree announced the in...

we show that every semi-artinian module which is contained in a direct sum of finitely presented modules in $si[m]$, is weakly co-semisimple if and only if it is regular in $si[m]$. as a consequence, we observe that every semi-artinian ring is regular in the sense of von neumann if and only if its simple modules are $fp$-injective.

For n ≥ 4, we describe Artin’s braid group on n strings as a crossed module over itself. In particular, we interpret the braid relations as crossed module structure relations. Subject classification: Primary: 20F36 57M05 57M20 57M25; Secondary: 18D50 18G55 20C08 55P48

We define an invariant of welded virtual knots from each finite crossed module by considering crossed module invariants of ribbon knotted surfaces which are naturally associated with them. We elucidate that the invariants obtained are non-trivial by calculating explicit examples. We define welded virtual graphs and consider invariants of them defined in a similar way. 2000 Mathematics Subject C...
