this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

The information has always been a valuable patrimony for the information systems that every company tries to capitalize as much as possible. With the web, the amount of information is increased and several problems arise for instance for the safety of the exchanged data but also to the semantic heterogeneity: the same information is very often represented in different ways in different informat...

Modified three-taxon analysis (m3ta), a method in which three-taxon statements are produced from a nonadditive binary coding of the original data, has been proposed as a model-free way of assessing monophyly of groups, utilizing the taxic concept of homology. In fact the taxic concept amounts to a model, and, further, one that seems to conflict directly with evolution. M3ta is a type of groupin...
