Self-healing polymers and fiber-reinforced polymer composites possess the ability to heal in response to damage wherever and whenever it occurs in the material. This phenomenal material behavior is inspired by biological systems in which self-healing is commonplace. To date, self-healing has been demonstrated by three conceptual approaches: capsule-based healing systems, vascular healing system...

With the growing complexity of parallel architectures, the probability of system failures grows, too. One approach to cope with this problem is the self-healing, one of the organic computing’s self-x features. Self-healing in this context means that computer clusters should detect and handle failures automatically. This paper presents a self-healing mechanism based on checkpointing, so that a c...

General concern and numerous studies of smart grid make it explicit that self-healing feature is an essential condition of power system intellectualization. Existing self-healing system based on traditional intelligence algorithms can’t simultaneously achieve satisfied effect and efficiency. To deal with the uncertainty factors and mass redundant data in the power system, rough set theory and i...

This paper attempts to identify one of the necessary conditions for self-healing, or self-repair, in complex systems, and to propose means for satisfying this condition in heterogeneous distributed software. The condition identified here is the following: For a system with a wide and open range of possible configurations to be self healing, it must possess suitable regularities, which can be re...

A flexible self-healing system capable of healing puncture damage has been manufactured. Our material consists of three layers: a poly(dimethyl siloxane) (PDMS) composite, embedded with a self-healing microcapsule system, sandwiched between two layers of poly(urethane) coated nylon. The total structure thickness ranges between 0.84 and 1.5 mm. A protocol is established in which samples are dama...

The classical definition of knowledge management promises to get the right knowledge to the right people at the right time so they can make the best decision [1]. Autonomic systems, on the other hand, are expected to find and apply the right knowledge for self-managing purposes without human intervention. This article discusses the components to be built around a system to enable self-healing a...

Since the 1950s, researchers have attempted to understand reports of distant or "psychic" healing, developing experimental protocols that test the distant healing hypothesis by measuring biological changes in a target system while ruling out suggestion or self-regulation as counterexplanations. This article provides a brief overview of these "healing analog" experiments. It also provides a summ...

Critical Software systems must recover when they experience degradation, either through external actors or internal system failures. There is currently no accepted generic methodology used by the software engineering community to design self-healing systems. Such systems identify when they require healing resources, and then change their own behavior to acquire and utilize these same resources....

Concrete is prone to crack formation in the tensile zone, which is why steel reinforcement is introduced in these zones. However, small cracks could still arise, which give liquids and gasses access to the reinforcement causing it to corrode. Self-healing concrete repairs and seals these small (300 µm) cracks, preventing the development of corrosion. In this study, a vascular system, carrying t...
