We present a framework for constructing structured realizations of linear dynamical systems having transfer functions of the form C̃( ∑K k=1 hk(s)Ãk) −1B̃ where h1, h2, ..., hK are prescribed functions that specify the surmised structure of the model. Our construction is data-driven in the sense that an interpolant is derived entirely from measurements of a transfer function. Our approach extends...

Business process models are the fundamental models of commercial systems. Therefore the business processes are issue of optimization as well as verification. When a business process has been identified as comparatively good (or optimal) it is of interest if the realization of the system still realizes this process. In this paper we present an approach how to verify such realizations. As applica...

Current work in surface realization concentrates on the use of general, abstract algorithms that interpret large, reversible grammars. Only little attention has been paid so far to the many small and simple applications that require coverage of a small sublanguage at different degrees of sophistication. The system TG/2 described in this paper can be smoothly integrated with deep generation proc...

Iterative Rational Krylov Algorithm (IRKA) of [11] is an effective tool for tackling the H2-optimal model reduction problem. However, so far it has relied on a first-order state-space realization of the model-to-be-reduced. In this paper, by exploiting the Loewner-matrix approach for interpolation, we develop a new formulation of IRKA that only requires transfer function evaluations without acc...

This paper presents a theoretical result in the context of realizing high speed hardware for parallel CRC checksums. Starting from the serial implementation widely reported in literature, we have identified a recursive formula from which our parallel implementation is derived. In comparison with previous works, the new scheme is faster and more compact and is independent of the technology used ...

This research aims to provide a deeper understanding of the unique features of CAD/CAM media tools and their applications. Moreover, it analyzes the role of the CAD/CAM media in the fabricating of physical models and the kind of added benefits they offer above and beyond those of traditional handmade physical models. This research concludes that certain aspects of CAD/CAM can aid in the digital...

This paper discusses the problem of parametrization of alI scalar rational fnnctions interpolating a given m y of points, with paramem the complexity, or McMillan degree. The main tool for tackling this problem is the socalled Limmer mmrlr. The L6ma matrix encodes the information about the minimal admissible complexity of the solutions, as a simple function of its rank. The minimal admissible c...

We prove a very general representation theorem for posets and, as a corollary, deduce that any abstract simplicial complex has a geometric realization in the Euclidean space of dimension dimP (∆) − 1, where dim P (∆) is the Dushnik-Miller dimension of the face order of ∆.

The external behavior of a state realization is the system (Z; W; B) where B = fw : (w; x) 2 B s for some xg. The state realization may be regarded as a presentation of its external behavior, with the elements of X as states. A state realization of ...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...
