Enterprise Modeling According to Enterprise Architects

A synchronous nucleation and passivation strategy for controllable synthesis of Au36(pa)24: unveiling the formation process and the role of Au22(pa)18 intermediate

作者： ma?gorzata pańkowska Department of Informatics University of Economics

In the context of enterprise modeling, this paper is to explain business modeling. The enterprise modeling has been developed to support different stakeholders in their decision-making processes. managers, auditors, enterprise architects, and business developers have particular expectations concerning the enterprise and they need conceptual modeling. Beyond that, business units, i.e., customers, producers, cooperators, and suppliers are interested in the conceptual modeling and enterprise models. In this paper, author argues that conceptual modeling is necessary for enterprise management, and particularly for internal auditing. Author uses the enterprise architecture approach, presents enterprise architecture frameworks;discusses enterprise modeling methods, languages, and tools to reveal the opportunity to apply conceptual modeling for enterprise management. This paper aims to present the application of Assurance map, tasks and goal modeling in an integrated conceptual model.

Angiosperms(flowering plants) are by far the most diverse land plant group with over 300,000 species. The sudden appearance of diverse angiosperms in the fossil record was referred to by Darwin as the “abominable mystery,”hence contributing to the heightened interest in angiosperm evolution. Angiosperms display wide ranges of morphological, physiological,and ecological characters, some of which have probably influenced their species richness. The evolutionary analyses of these characteristics help to address questions of angiosperm diversification and require well resolved phylogeny. Following the great successes of phylogenetic analyses using plastid sequences,dozens to thousands of nuclear genes from next-generation sequencing have been used in angiosperm phylogenomic analyses, providing well resolved phylogenies and new insights into the evolution of angiosperms. In this review we focus on recent nuclear phylogenomic analyses of large angiosperm clades, orders, families,and subdivisions of some families and provide a summarized Nuclear Phylogenetic Tree of Angiosperm Families. The newly established nuclear phylogenetic relationships are highlighted and compared with previous phylogenetic results. The sequenced genomes of Amborella,Nymphaea, Chloranthus, Ceratophyllum, and species of monocots, magnoliids, and basal eudicots, have facilitated the phylogenomics of relationships among five major angiosperms clades. All but one of the 64 angiosperm orders were included in nuclear phylogenomics with well resolved relationships except the placements of several orders. Most families have been included with robust and highly supported placements, especially for relationships within several large and important orders and ***, we examine the divergence time estimation and biogeographic analyses of angiosperm on the basis of the nuclear phylogenomic frameworks and discuss the differences compared with previous analyses. Furthermore,we discuss the implicatio

The authors introduce a notion of dynamic bifurcation for nonlinear evolution equa- tions, which can be called attractor bifurcation. It is proved that as the control pa- rameter crosses certain critical value, the system bifurcates from a trivial steady state solution to an attractor with dimension between m and m + 1, where m + 1 is the number of eigenvalues crossing the imaginary axis. The attractor bifurcation theory presented in this article generalizes the existing steady state bifurcations and the Hopf bifurcations. It provides a uni?ed point of view on dynamic bifurcation and can be applied to many problems in physics and mechanics.
