A parametric Colored Petri net model of the switched Ethernet network with the tree-like topology is developed. The model’s structure is the same for any given network and contains fixed number of nodes. The tree-like topology of a definite network is given as the marking of dedicated places. The model represents a network containing workstations, servers, switches, and provides the evaluation ...
The Visual SQL-X system is presented to generate arbitrarily complex XML documents from a graphical query on a relational database. The query describes the structure of the resulting document through a tree-like representation of its structure. The system generates the XML document through the synthesis of a SQL query and a “summarization” algorithm on the resulting table.
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
one of the most important factors in study of project’s , is the study of environmental opportunities factors the permanent study of environmental opportunity factors . the study of permanent environmental changing and knowing golden threats’ cooperate with possible threats and at the result in structure forming and future skeleton of organization has a vital effects . the petrochemical industr...
This paper presents several distributed and decentralized strategies used for token traversal in spanning forest over DTMs. DTMs or Delay Tolerant Mobile ad hoc networks are characterized by some undesirable behaviors like the disappearance of mobile devices, connection disruptions, network partitioning, etc. Providing efficient communications in DTMs is a very challenging issue. Techniques bas...
Mining for frequent episodes has been an active research area in recent years. Numerous algorithms have been developed to discover different types of episodes, where most of them adopt an a priori-like approach that generates candidates and then recognises these candidates to determine their support. However, such methods are computationally expensive, depending on the size and structure of the...
