In this paper we apply a model-driven engineering approach to designing domain-specific solutions for robot control system development. We present a case study of the complete process, including identification of the domain metamodel, graphical notation definition and source code generation for subsumption architecture – a well-known example of robot control architecture. Our goal is to show th...

Industrial control systems are taught best using real systems. Such systems can be expensive, dangerous, and may break easily. In the other side simulations often do not react like the real system. IEC 61499 automation standard supports the current control system trend toward networks of event-driven distributed devices. Support for event driven control applications is new in IEC 61499 as are t...

Security is among the most successful applications of aspectoriented concepts. In particular, in role-based access control, aspects capture access conditions in a quite modular way. The question we address in this paper is how can aspects be generated from access control policies under a validated process? We present a metamodel-based transformation from SecureUML, a rolebased access control la...

Achieving the organizational objectives needs employees’ behavior and their collaboration with management. Strategic behavior-driven is depend on different factors. The aim of this article is to determine the impact of factors on strategic behavior-driven. A conceptual model was developed and tested on a survey in Social Insurance Company of Tehran which employees’ participated. Data collected ...

Active Queue Management (AQM) is investigated to avoid incipient congestion in gateways to complement congestion control run by the transport layer protocol such as the TCP. Most existing work on AQM can be categorized as (1) ad-hoc event-driven control and (2) time-driven feedback control approaches based on control theory. Ad hoc event-driven approaches for congestion control, such as RED (Ra...

Entrepreneurship is influenced by many factors and environments such as institutions. Institutions have an important role to play in the individual's tendency toward necessity and opportunity entrepreneurship. The purpose of this paper was to examine the impact of institutional quality (property rights) on opportunity and necessity entrepreneurship. The results, based on unbalanced panel data f...

Aiming at the lateral stability control problem of distributed driven electric vehicles under high speed steering condition, a hierarchical algorithm direct yaw moment is designed. The upper takes 2-DOF vehicle model as reference and uses sliding mode to obtain required by tracking desired velocity side-slip angle. lower optimizes distribution four wheel torque with minimum tire utilization rat...
