SUMMARY We describe an algorithm and software tool for comparing alternative phylogenetic trees. The main application of the software is to compare phylogenies obtained using different phylogenetic methods for some fixed set of species or obtained using different gene sequences from those species. The algorithm pairs up each branch in one phylogeny with a matching branch in the second phylogeny...

Coordination congruence has been defined as the match between coordination requirements and the actual coordination behavior of a team, where requirements are calculated based on underlying task dependencies and behavior based on communication patterns. In this paper we propose to expand the notion of congruence in two distinct ways. First, we use the concept of shared mental model as a determi...

These are lecture notes for the workshop “Syzygies of algebraic varieties” that took place November 20–22, 2015 at University of Illinois, Chicago. The goal of these lectures is to explain the method of Kempf collapsing and how to use it to calculate Betti numbers of algebraic varieties. This technique can only be fully executed in very special cases, but when it does work, it gives a surprisin...

The paper illustrates the application of a combined adaptive particle swarm optimization (A-PSO) algorithm and the finite strip method (FSM) to the lay-up optimization of symmetrically fiber-metal laminated (FML) composite shallow shell panels for maximizing the fundamental frequency. To improve the speed of the optimization process, adaptive inertia weight was used in the particle swarm optimiz...

The growth parameters, mortality rates and exploitation population dynamic parameters and exploitation rate of Psettodes erumei were assessed between July 2010 to June 2011 using length frequency analysis. The data were collected from landing sites of Jask, Bandar Abass, Kong and Qeshm Hormozgan province waters. Using total weight (W) and total length (TL) data, the length- weight relationship ...

one of the most valid and efficient models of long rod projectile penetration in homogeneous targets is tate and alekseevskii’s (a&t;) model. based on tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. the proposed collision speed-penetration depth diagrams are developed using tate’s model. in this way, v...
