Charting the landscape of enterprise architecture management

Todays enterprises are faced with the challenge of an everchanging environment, which they continuously have to adaptto. A commonly accepted means to support an enterprisein the transformation process and furthermore enhance thealignment between business and IT is enterprise architecture(EA) management, which provides a holistic perspectiveon the enterprise. In order to support an enterprise inthe transformation process, EA management creates architecturaldescriptions of current, planned, and future statesof the enterprise. Reecting the aforementioned importanceof EA management a plurality of approaches for establishingan EA management function in an enterprise have beenproposed by researchers, practitioners, and standardizationbodies. The approaches vary widely in respect to the proposedmethods, models, and languages.The objective of this article is to analyze the state-of-theartin EA and EA management respectively. Therefore, anextensive literature survey on publications in the area is performed.Criteria for the analysis are inter alia the distribution of papers over time, their regional distribution, type ofpublication, number of references of an article, and the involvedauthors groups. Thereby the article seeks to give anoverview on the current research occupation in the eld ofEA management

Obtaining of high-quality InP active layers in geterostructure’s composition for Gunn diodes

It is shown that for epitaxial InP layers obtained by liquid-phase epitaxy complex dopping of indium melts by optimal concentrations of rare-earth Yb and isovalent element Al promotes useful increase of cleaning effect from background impurities and leads to growth of its structural perfection. The concentration of electrons in InP layers decreases and their mobility increases on optimal amounts of Yb and Al in the melt. This technology may be used in producing structures for Gunn diodes, photoreceivers and other optoelectronic devices
