Jacroux (1985) extended the definition of Regular graph designs of Mitchell and John (1976) to Semi-regular graph (SRG) designs, and studied the type 1 optimality of block designs. Here, the construction and optimality of some more SRG designs are discussed. Moreover, in this investigation, it is established that a class of two associate partially efficiency balanced design is, in fact SRG desi...

We prove that if a right Markov process is associated with a semi-Dirichlet form, then the form is necessarily quasi-regular. As an applications, we develop the theory of Revuz measures in the semi-Dirichlet context and we show that quasi-regularity is invariant with respect to time change.

In this paper, we present our experiences on managing semi-structured data in relational databases. We use a Java package built on top of relational database for store and query semi-structured data. In this work, we introduced a more complete data model, a flexible storage scheme, and a compact metedata structure for processing regular path expressions.

It is known that a strongly regular semi-Cayley graph (with respect to a group G) corresponds to a triple of subsets (C, D, D') of G. Such a triple (C, D, D') is called a partial difference triple. First, we study the case when D U D' is contained in a proper normal subgroup of G. We basically determine all possible partial difference triples in this case. In fact, when \G\ f 8 nor 25, all part...

We use semi-regular entities to denote the entities different from penetrates that participate in the protocol on behalf of themselves such as customers in e-commerce.

this article is devoted to kamāl al-dīn al-fārsī’s (d. 1319) additions to some remarks contained in book xiii of al-ṭūsī’s taḥrīr uṣūl al-handasa, concerning the construction of a semi-regular polyhedron inscribed into a sphere using the movement as a way for the construction. this treatise is one treatise among ten found in a codex preserved at the bibliothèque nationale de tunis.

Using only basic topological properties of real algebraic sets and regular morphisms we show that any injective regular self-mapping of a real algebraic set is surjective. Then we show that injective morphisms between germs of real algebraic sets define a partial order on the equivalence classes of these germs divided by continuous semi-algebraic homeomorphisms. We use this observation to deduc...

in recent years, many changes have been observed in buying culture of customers and developing chain stores in iran. moreover, need to be more competition in business environments made necessary the stablishment of chain stores, the creation of competitive advantage and long relations to the costumers. regular marketing is a response to stores requirement when establishing such a win-win long r...

Owing to the high expressiveness of regular expression, it is frequently used in searching and manipulation of text based data. Regular expression is highly applicable in processing Latin alphabet based text, but the same cannot be said for Hangeul∗, the writing system for Korean language. Although Hangeul possesses alphabetic features within the script, expressiveness of regular expression pat...
