In this paper we extend Kalman's concept of partial realization and deene generalized partial realizations of nite matrix sequences by descriptor systems. Our deenition is in agreement with the realization theory for deterministic boundary value descriptor systems 15]. The aim of this contribution is to prove a counterpart of Kalman's main theorem of realization theory for generalized partial r...

The selfdual one-terminal-pair cmstmt-resistsme networks obtained by Tea&ado’s mirror-an&ymmebical disectbn of twodimensiomll region9 of resjstan~ are shown to helong to the planar reflex suhchws of the class of se&dual maps pioneered by Smith and Tutte.

Food security is a key component of state security, and every country, especially some great powers in the world, has been paying more attention to national food security and its security system. This paper aimed at applying grey model to food security assessment in the province scale from statistical data and developing a prototype of food security assessment system in Liaoning Province. First...

political evolutions and struggles of 19th century prepared the ground for realization of nationalities and emergence of nationalist movements. the realization of national identity in countries such as iran, turkey and egypt was partly due to the emphasis of governments on glorious history or ancient modernity of these nations. emergence of nationalism in any country is affected by political, ...

one of the important methods of plant propagation in large scale so as genetic manipulation and artificial seed production is somatic embryogenesis technique. the obtained results from this methods related to different factors including condition of culture medium. therefore, the aim of this study conduction were determining the role of molybdenum during carrot petiole somatic embryogenesis. at...

The objective of technical trading is to identify profitable conditions for the entry and exit of market positions. This paper explores the potential use of three common momentum indicators to classify the outcome (return) of a position defined by trading signals of a Simple Moving Average system. The collection of positions associated with each randomly selected security was grouped into outco...

The graph realization problem is that of computing the relative locations of a set of vertices placed in Euclidean space, relying only upon some set of inter-vertex distance measurements. This paper is concerned with the closely related problem of determining whether or not a graph has a unique realization. Both these problems are NP-hard, but the proofs rely upon special combinations of edge l...
