Since information of various sensitivity levels may be carried over a single network. Each sensitivity level needs a certain level of security. Technology that supports such models is often referred to as multi-level security (MLS). IPsec mechanism can easily support MLS (information flow security policy) networking. MLS networking requires the use of(More)
Fuzzy Petri Net for Web Service Composition (FPN4WSC) aims to compose the individual web services into more complex one. It is a workflow model which is hybridization between Petri net, SHOP2, and fuzzy logic. Petri net allows user to specify his request as a workflow. SHOP2 is used as an Artificial Intelligence (AI) planning system to get a plan for the(More)
Computer architects have always strived to increase the overall speed of processing for the CPUs. utilizing a reserved unused machine code "A5H", we can expands the tradition instruction set architecture (ISA) for the μCs-51 family, in this paper we introduce modification of internal architecture for the μCs-51 and their ISA to improve the overall μC(More)
