A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

abstract niklas luhmann was one of the prominent thinkers in the realm of sociology and the philosophy of social sciences. his approach was a systems approach. he classified the realm of reality and its entities into four groups that consisted of: machines, organisms, psychic systems, social systems. he belonged to the second wave of systemic thought and focused on the complexity and emergence ...

at current study, the relationship between transnational law, globalization and international solidarity has been studied, and talcott parsons's structural functionalism approach has been used as theoretical framework. this study is based on the assumption that: any inconsistency between the legal system and other social systems can result in social anomie. in the next part of the paper, t...

optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...

among the most important sources of competitive advantage, is creating and developing strategic alignment competency. strategic alignment, literally, is an abstract and qualitative concept. and a qualitative concept while not been quantified and operationalized, does not worth paying attention practically. this article basing on a general formula and taking systems dynamics approach, suggests a...

This paper presents a numerical matrix method based on Bernstein polynomials (BPs) for approximate the solution of a system of m-th order nonlinear Volterra integro-differential equations under initial conditions. The approach is based on operational matrices of BPs. Using the collocation points,this approach reduces the systems of Volterra integro-differential equations associated with the giv...

In this paper, we propose an approach for automatic generation of novel intrusion signatures. This approach can be used in the signature-based Network Intrusion Detection Systems (NIDSs) and for the automation of the process of intrusion detection in these systems. In the proposed approach, first, by using several one-class classifiers, the profile of the normal network traffic is established. ...

The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
