Chloride diffusion and penetration, consequently chloride-induced corrosion of reinforcement, are among the most common mechanisms deterioration concrete structures, and, as such, widely deeply investigated well. The benefits using Ultra-High Performance (Fiber-Reinforced) Concrete—UHP(FR)C to extend service life structures in “chloride attack” scenarios have been addressed, mainly focusing on ...

We describe a novel framework for designing and implementing agent based simulations of the smart electrical grid. The framework is based on two primary concepts. First, the eletrical grid system is separated into semi-autonomous microgrids, each with their own set of hierarchically organized agents. Second, models for automating decision-making in the grid during crisis situations are independ...

Autonomous mobile nodes in mobile wireless sensor networks (MWSN) allow self-deployment and self-healing. In both cases, the goals are: (i) to achieve adequate coverage; and (ii) to extend network life. In dynamic environments, nodes may use reactive algorithms so that each node locally decides when and where to move. This paper presents a behavior-based deployment and self-healing algorithm ba...

Autonomous networking has become the buzzword for attempts of building high-scalable network architectures, which are self-organizing, selfmaintaining and self-healing. Few of these approaches were successful and none has shown to provide all the promised functions. We try to study the processes in computer networks using molecular processes as the paradigm. This novel approach shows many simil...

The deregulated markets and other factors are pushing power systems to their limits accentuating the need for more robust control. This paper presents a conceptual overview of a control approach for supporting a self-healing power system based on a distributed autonomous architecture and a set of coordinated closed loop controls. The proposed architecture is modular and scalable from the viewpo...

The autonomous repair mechanism of creep cavitation during high-temperature deformation has been investigated in Fe-Au and Fe-Au-B-N alloys. Combined electron-microscopy techniques and atom probe tomography reveal how the improved creep properties result from Au precipitation within the creep cavities, preferentially formed on grain boundaries oriented perpendicular to the applied stress. The s...

The growing complexity of distributed systems demands for new ways of control. This work addresses self-healing in distributed environments. The term self-healing represents a quite new area of research and is used in a fairly broad way, but can be seen as dynamic fault tolerance. This work proposes generic concepts and algorithms to build self-healing systems. The detection of node failures in...

Introduction We consider the future of ICS cyber security. As best as we can see, much of this future unfolds in the context of the Internet of Things. In fact, we envision that all industrial and infrastructure environments, and cyber-physical systems in general, will take the form reminiscent of what today is referred to as the Internet of Things. Internet of Things is envisioned as multitude...
