“…An alternative to this is the term 'self-repairing' often commonly associated with physical systems such as electronics or mechanical systems that can similarly exhibit some ability to regain a fully functional state. Self-healing can be seen as a bottom-up approach, where the components of the system heal any damage from the inside [12]. Much work conducted into selfhealing technologies has focused upon the material level, such as self-healing composites [13,14].…”

“…Designing for selfrepair is a top-down approach where the system is designed to have the ability to maintain its own function through external factors such as diagnosis and reconfiguration. Self-repairing autonomous systems or electronics are able to detect and diagnose faults for example and either isolate the fault and replace them or through external action repair the damage [12]. Such characteristics provide a system that can therefore identify and correct unanticipated damage.…”

“…This is because in general terms, what is often desired is a system that is able to "Maintain some degree of functionality after a failure has occurred" [3]. For a further discussion on the taxonomy of selfhealing and self-repairing systems and their differences can be found in [12] To achieve a self-repairing system, it is clear that the system must have an element of selfawareness. Amor-Segan et al [4] originally stated that what is desired is a system that has "the ability to autonomously predict or detect and diagnose failure conditions, confirm any given diagnosis, and perform appropriate corrective intervention(s)".…”

Despite significant advances in modelling and design, mechanical systems almost inevitably fail at some point during their operative life. This can be due to a pre-existing design flaw, which is usually overcome in a revision, or more commonly due to some unexpected damage during operation. To overcome a failure during operation, a new method in designing machines or systems is proposed that creates a result, that is, resilient to both expected and unexpected failure. By shifting the focus from a detailed assessment of the underlying cause of failure to how that failure will manifest, a system becomes inherently resilient against a wide range of failure modes. The proposed process involves five steps: cause, detection, diagnosis, confirmation and correction. This is demonstrated with an application to a generic 4 bar linkage mechanism. Through this process, the system is able to return to a near perfect state even after a permanent deformation occurs in the mechanism. These results show the potential that this self-repairing design process has applications including robotics, manufacturing and other systems.

“…Self-healing is an obvious subset of this overarching definition, yet it is a critical ability for next-generation soft robots and holds equal importance to general damage resilience. The idea that robots can self-heal, self-repair, or correct for damage that has occurred like biological systems is a concept that is still relatively new (Frei et al, 2013), but one that would continue to distinguish soft robots from their rigid-bodied counterparts (Bauer et al, 2014).…”

Advances in soft robotics will be crucial to the next generation of robot-human interfaces. Soft material systems embed safety at the material level, providing additional safeguards that will expedite their placement alongside humans and other biological systems. However, in order to function in unpredictable, uncontrolled environments alongside biological systems, soft robotic systems should be as robust in their ability to recover from damage as their biological counterparts. There exists a great deal of work on self-healing materials, particularly polymeric and elastomeric materials that can self-heal through a wide variety of tools and techniques. Fortunately, most emerging soft robotic systems are constructed from polymeric or elastomeric materials, so this work can be of immediate benefit to the soft robotics community. Though the field of soft robotics is still nascent as a whole, self-healing and damage resilient systems are beginning to be incorporated into three key support pillars that are enabling the future of soft robotics: actuators, structures, and sensors. This article reviews the state-of-the-art in damage resilience and self-healing materials and devices as applied to these three pillars. This review also discusses future applications for soft robots that incorporate self-healing capabilities.

Abstract-In today's world, information security of an organization has become a major challenge as well as a critical business issue. Managing and mitigating these internal or external security related issues, organizations hire highly knowledgeable security expert persons. Insider threats in database management system (DBMS) are inherently a very hard problem to address. Employees within the organization carry out or harm organization data in a professional manner. To protect and monitor organization information from insider user in DBMS, the organization used different techniques, but these techniques are insufficient to secure their data. We offer an autonomous approach to self-protection architecture based on policy implementation in DBMS. This research proposes an autonomic model for protection that will enforce Access Control policies, Database Auditing policies, Encryption policies, user authentication policies, and database configuration setting policies in DBMS. The purpose of these policies to restrict insider user or Database Administrator (DBA) from malicious activities to protect data.
