information security is one of the most important enterprise assets. for any organization, information is valuable and should be appropriately protected. also, security is to combine systems, operations, and internal controls to ensure the integrity and confidentiality of data and operation procedures in an organization. knowing the fact that with serious threat of unauthorized users on the int...

A stochastic aggregation technique is developed and used to reduce generally distributed stochastic transition systems to a soluble example. By aggregating carefully, we can derive the entire stationary distribution for the original stochastic transition system. This paper examines the possibility of constructing a solution technique for generally distributed process algebras. Further, we demon...

Quadratic pencils arise in many areas of important applications. The underlying physical systems often impose inherent structures, which include the predetermined inner-connectivity among elements within the physical system and the mandatory nonnegativity of physical parameters, on the pencils. In the inverse problem of reconstructing a quadratic pencil from prescribed eigeninformation, respect...
