The fundamental requirement for the autonomous capsule-based self-healing process to work is that cracks need to reach the capsules and break them such that the healing agent can be released. Ignoring all other aspects, the amount of healing agents released into the crack is essential to obtain a good healing. Meanwhile, from the perspective of the capsule shapes, spherical or elongated capsule...

Synthetic materials that are capable of autonomous healing upon damage are being developed at a rapid pace because of their many potential applications. Despite these advancements, achieving self-healing in permanently cross-linked hydrogels has remained elusive because of the presence of water and irreversible cross-links. Here, we demonstrate that permanently cross-linked hydrogels can be eng...

We are motivated to better understand how adaptive locomotion (rough terrain locomotion, turning, gait transition, etc) can be realized using a quadrupedal platform with constrained resources. These constraints include computational power limitation, no accurate force/torque sensing, and partial sensing of robot’s kinematic states. These constraints arise from the fact that we are designing and...

We describe a project designed to use the power of online virtual worlds as a place of camaraderie and healing for returning United States military veterans–a virtual space that can help them deal with problems related to their time of service and also assist in their reintegration into society. This veterans’ space is being built in Second Life ® , a popular immersive world, under consultation...

A self-healing, self-organizing evolvable hardware system is developed using SRAM-based reconfigurable Field Programmable Gate Arrays (FPGAs) and group testing principles. It employs adaptive group testing techniques to autonomously maintain resource viability information as an organic means of transient and permanent fault resolution. Reconfigurability of the SRAM-based FPGA is leveraged to id...

Nowadays, distributed energy sources are widely used to supply demand in micro grids (MGs) especially the green buildings. Despite increasing number of intermittent resources, MGs have essential influence on decreasing use conventional generation, but it give rise new challenges terms management, stability and reliability system. Multi-agent systems (MASs) as smart units been recently. However,...
