This paper is an expanded and more detailed version of the work [1] in which the Operator Quantum Error Correction formalism was introduced. This is a new scheme for the error correction of quantum operations that incorporates the known techniques — i.e. the standard error correction model, the method of decoherence-free subspaces, and the noiseless subsystem method— as special cases, and relie...

Currently the documentation of an Enterprise Architecture (EA) is performed manually to a large extent. Due to the intrinsic complexity of today’s organizations this task is challenging and often perceived as very time-consuming and error-prone. Recent efforts in research and industry seek to automate EA documentation by retrieving and maintaining relevant information from productive systems. I...

This study proposed a hybridization of higher-order Random Boolean kSatisfiability (RANkSAT) with the Hopfield neural network (HNN) as neuro-dynamical model designed to reflect knowledge efficiently. The learning process has undergone significant changes and improvements according various types optimization problems. However, HNN is associated some limitations which include storage capacity bei...

A New Look at Robust Estimation and Identification by Keith Evan Schubert Estimation and identification are important areas of almost every problem in science and engineering. A typical way of stating an estimation or identification problem is that there is a system, described by a matrix, A, with inputs, x, and outputs, b. The inputs and outputs could either be matrices or vectors. The equatio...

Enterprise architectures (EA) can be used for analyses in different ways and thus can support the decision making process that has to cope with an increasing number of changes, the clarification of the extent of changes and the complexity of these changes. A gap analysis is used in the context of EA to identify differences between two states of an EA. Formal models of an EA allow tool support a...

Enterprise architecture (EA) management forms a commonly accepted means to enhance the alignment of business and IT, and to support the managed evolution of the enterprise. One major challenge of EA management is to provide decision support by analyzing as-is states of the architecture as well as assessing planned future states. Thus, different kinds of analysis regarding the EA exist, each rel...
