Microcapsule self-healing technology is one of the effective methods to solve durability problem cement-based composites. The evaluation method efficiency microcapsule composites difficulties that limits technology. This paper attempts characterize by acoustic emission (AE) parameters, which provides a reference for Firstly, kind microcapsules were prepared, and added into prepare compression s...

Principles for designing self-healing water-splitting catalysts are presented together with a formal kinetics model to account for the key chemical steps needed for self-healing. Self-healing may be realized if the catalysts are able to self-assemble at applied potentials less than that needed for catalyst turnover. Solution pH provides a convenient handle for controlling the potential of these...

We present GS, a distributed algorithm for scalable self-configuration and self-healing in multi-hop wireless sensor networks. The algorithm enables network nodes in a 2D plane to configure themselves into a cellular hexagonal structure where cells have tightly bounded geographic radius and the overlap between neighboring cells is low. The structure is self-healing under various perturbations, ...

Service composition is an important means for integrating the individual web services to create new value added systems that can satisfy complex requirements. Such applications are subject to unexpected failure owing to the distributive and heterogeneous environment of web service. In this paper, we propose a Petri nets-based method to model and analyse the self-healing service composition. Asp...
