Application contexts such as the support to service-enhanced products require the interplay of various collaborative networks along the product life-cycle. Based on the solar energy parks case, various longand short-term networks are identified and their inter-dependencies briefly analyzed. A cloud-based collaborative environment is developed to support the various types of networks. Presented ...

On-orbit servicing (OOS) is growing in importance for the sustainment of certain satellite systems. Although it is more economical to replace satellites in many cases, OOS could be beneficial or even critical for more expensive satellites such as Space-Based Laser and constellations such as the Global Positioning System. Some future OOS missions including refueling and modular component replace...

In this second of three short papers, I introduce some of the basic concepts of space robotics with an emphasis on some specific challenging areas of research that are peculiar to the application of robotics to space infrastructure development. The style of these short papers is pedagogical and the concepts in this paper are developed from fundamental manipulator robotics. This second paper con...

In this paper we propose scalable proxy servers cluster architecture of interconnected proxy servers for high quality and high availability services. We also propose an optimal regional popularity based video prefix replication strategy and a scene change based replica caching algorithm that utilizes the zipf-like video popularity distribution to maximize the availability of videos closer to th...

Interest in modular satellites has increased recently. In this paper, we present our approach for planing an OnOrbit-Servicing (OOS) task for a robotic servicer. One key challenge is the gap between the symbolic planing of action sequences and their execution in the continuous space. To bridge this gap, we propose a sampling based workspace description. It is queried by an Hierarchical Task Net...

An effective warranty servicing strategy should be made considering both warranty cost and product availability. Based on the two-dimensional free repair warranty, a strategy combining the imperfect preventive maintenance and minimal repair is proposed where the imperfect preventive maintenances are implemented in a special subregion of the warranty and all other failures are repaired minimally...
