Abstract

The objective of operating system (OS) discovery is to find which OSs are running on computers in a given network. There are two existing strategies for OS discovery—active and passive—each having fundamental limitations. This paper discusses how the theory of diagnosis can be used to address, in a simple and elegant way, the problems associated with OS discovery. The problems are formalized in a logical framework and solutions are obtained through automated reasoning. The result of using such a knowledge‐oriented approach is a natural unification of the active and passive methods of OS discovery in a hybrid approach. This paper also illustrates the benefits of the hybrid approach by comparing its accuracy with other existing OS discovery tools through a large‐scale experiment.

Recently, a novel concept for the computation of essential features of the dynamics of Hamiltonian systems (such as molecular dynamics) has been proposed. The realization of this concept had been based on subdivision techniques applied to the Frobenius-Perron operator for the dynamical system. The p

An approach to parameter identi"cation for the single-degree-of-freedom (s.d.o.f.) system is presented. It "ts into the group of parametric system identi"cation methods that use a structured mathematical model. It uses the free acceleration response of the system in order to estimate the parameters
