An autonomic computing system has four basic characteristics, namely self-configuration, self-optimization, self-healing and self-protection. Autonomic computing can be viewed as a new computing paradigm and it is becoming a hot research topic in distributed and ubiquitous computing area. In this paper, we not only discuss the four basic aspects of autonomic computing comprehensively based on o...

A protocol is described to assess self-healing of crack damage in a polymer coating deposited on a substrate containing a microvascular network. The bio-inspired coating/substrate design delivers healing agent to cracks in the coating via a three-dimensional microvascular network embedded in the substrate. Through capillary action, monomer flows from the network channels into the crack plane wh...

The ever-increasing complexity of software systems makes it progressively more difficult to provide dependability guarantees for such systems, especially when they are deployed in unpredictably changing environments. The Component Based Software Development initiative addresses many of the complexity related difficulties, but consequently introduces new challenges. These are related to the lack...

One of the main objectives of self-adaptive systems is to reduce maintenance costs through automatic adaptation. Self-healing is a self-adapting property that helps systems return to a normal state after a fault or vulnerability exploit has been detected. The problem is intuitively appealing as a way to automate the different type of maintenance processes (corrective, adaptive and perfective) a...

Many types of healing agents have been investigated. These agents are processed in different ways, such as adhesive polymer in capsules or hollow fibre glasses, bacteria in porous aggregates and geo-materials directly incorporated in the cementbased materials. In this study, sodium silicate powder is encapsulated in polystyrene particles (polystyrene particle containing sodium silicate is defin...

Wireless Mesh Networks are self organizing, self configurable, self-healing wireless networks. Due to complex infrastructure of WMN, to maintain the quality of service is a tedious task. In this paper, a QoS routing scheme has been proposed. This scheme is based on two models named fuzzy inference system model and agent based model. Both models are installed on each and every node on the networ...

Intelligent Tutoring Systems (ITS) can be designed to improve learning and performance through Pedagogical Agents (PAs) that are designed to foster self-regulated learning through interactions and exchange of information with human learners. PAs are intelligent and follow rational behaviors, but to adaptively track students’ progress, they need to be systematically and specifically designed. Ho...

While original epoxy resin-based self-healing systems used the commercially available endo-isomer of dicyclopentadiene (DCPD), the exo-stereoisomer is known to have much faster olefin metathesis reaction rates with first-generation Grubbs' catalyst. Here, we measure the energy to failure of healed specimens as a function of healing time and compare the kinetics of damage repair for endo- and ex...
