The Molecular Evolution of Snakes as revealed by Mitogenomic Data

Snakes (Serpentes) are a diverse suborder of reptiles that, along with lizards and amphisbaenians, belong to the reptilian order Squamata. The phylogenetic position of snakes relative to lizards and amphisbaenians has been debated for about 140 years. Despite the many morphological and molecular studies that had been done, no consensus had been reached as to the phylogenetic position of snakes or

Fault Behaviour of Wind Farms with Fixed-Speed and Doubly-Fed Induction Generators

Abstract in UndeterminedThis paper focuses on the fault current contribution of wind farms with Fixed-Speed (FSIG) and Doubly-Fed Induction Generators (DFIG). The fault current delivered by a single FSIG during both symmetrical and unsymmetrical faults is found analytically and validated through simulations. Simulations of a detailed model of a wind farm with several FSIG or DFIG are then performe

Max-Min Fair Optimization Models in Network Design

Max-min fairness (MMF) is a general objective of multi-criteria optimization with important and natural applications in communication network design. The notion of MMF and optimization models involving MMF seem not to be commonly known to network designers and therefore they are not used to an extent they deserve. Moreover, the MMF approaches are sometimes “reinvented”, in some cases not correctly
