Reactions of Robot Critical Components to Nuclear Radiation

A typical robotic system includes a few key components, which are motor, speed reducer, drive, controller, power supply, and mechanical frame, in both robot manipulators and/or mobile robots (wheeled or legged). While all the components are necessary, three individuals are critical and stand out, which are speed reducer, motor, and battery (especially Lithium-ion battery), respectively. The reason for those is twofold: failure of any of them will fail the entire system, and the cost of the three takes more than 80% of the total cost. In the robotic field, we have seen numerous works studying/improving the performance of a robot at the system level but very few focusing at the component level, especially when a robot operates in the nuclear environment. Radiation damage to electronic devices (including H-bridge drives) has long been studied in both theory and experiment. The study on the three critical components has received much less attention. In this talk we report our current studies on the radiation impact to harmonic drive (a speed reducer used in high-end robotic systems), brushless DC motor, and Lithium-ion battery. Our studies have invented new approaches for evaluating the performance of individual components, and reveal how the radiation will affect the performance of the latter. Both theoretical and experimental studies will be presented. The degraded performance of the components may impact or even fail the entire system, regardless of it being a robot manipulator or a mobile robot. We will therefore discuss how to design and develop radiation-hardened components, which can endure a robot in radiation-filled environments.

Multi-Cloud Service Communities: Formation and Trust Challenges
 

Cloud computing is the standard computing paradigm adopted not only in small and medium startups, but also in major companies in the prominent majority of industrial sectors. The rapid expansion in the use of cloud facilities is due to the flexible concept of services computing where applications, infrastructures, and platforms are offered as services. In this new reality, gathering cloud services within virtual communities has gained an increasing interest in the recent years. Communities of cloud services provide platforms that aim to facilitate the discovery and composition of services while supporting resource scaling. However, the existing community formation models have several limits at the architectural, business and security levels preventing their adoption as industrial solution. From the architectural perspective, the existing community formation models rely on a centralized architecture wherein a central entity is responsible for managing the community formation process. However, the fact that services are being hosted in different and geographically distributed cloud data centers requires a fully distributed community formation algorithm. From the business perspective, the current models ignore the market reality of deployed and offered services. In fact, services are owned by cloud providers that differ in their business capabilities, which demotivates the participation of the well-positioned services in such a process unless they receive some privileges. From the security perspective, the current approaches relay on classic monitoring solutions that work for small settings, but unable to scale up when the number of services goes beyond a certain threshold. In this talk, I will present recent solutions to these problems and developments conducted in my research lab involving graduate students and collaborators. Game theoretical models for dynamic and distributed formation of secured cloud communities against malicious services will be presented along with theoretical and simulation results using real datasets. I will capitalize on: 1) a model that classifies services as leaders and followers based on the strength of the cloud that they are deployed in and formalizes the community formation problem as a virtual trading market using a Stackelberg game model; 2) a trust establishment framework resilient to collusion attacks that occur to mislead trust results; and 3) a trust-based hedonic coalitional game that enables services to form trustworthy multi-cloud communities.

Cybersecurity in the Cloud Era: Drawing Parallels between Nature and Cloud Computing For Enhanced Resilience and Survivability

Abstract
The rapidly changing cyber-space landscape provides an explanation to the increasing complexity of current and future security challenges. With this increasing threats of cyber-attacks. As Organisations are increasingly adopting cloud-computing as the foundation for their IT infrastructure, the reliability of inherently complex cloud systems becomes under test. Despite the wider impact of security threats, the current practices for security countermeasures are still mostly reactive and following conventional approaches. In cloud computing, for instance, the robustness of the infrastructure and service and the overall survivability is enhanced, mainly, by creating redundancy for backup in times of fault, failure or attack. Biological systems are inherently much more complex, yet highly reliable. The strengths inherent in biological systems resides in the ability of autonomous entities to make local decisions, continuously coordinate and share information, while maintaining a global form of order. Furthermore, the challenges of attaining survivability have also been successfully addressed by nature, and effectively demonstrated in attributes of collaborative communities. This success in natural systems could provide inspiration for unconventional methods to solve unique problems in the computing continuum, generally, and in Cloud computing, more specifically. In this talk, I will shed some light on the changing cyber-space, emphasising more on the added complexity with the adoption of cloud computing, where I will provide an analysis of the State of the Art of Cloud security countermeasures and explain the need for unconventional approaches to tackle cyber-attacks. I will then draw parallels between capabilities in nature such as those demonstrated in multi-cellular biological systems and by the predation avoidance in primate in predator-prey communities, and capabilities in security systems in cloud environments.
