Servicing industrial machinery and automation systems over their life targets at fast response and fast resolution. It requires skills, engineering knowledge and various data about the machine, its industrial environment, data from automation systems in the plant and historical information, which needs to be collected, correlated and analyzed. The advent of tiny smart devices such as RFID and n...

Modern I/O subsystems have increased their capacity and density but their performance has not been improved accordingly. To address this problem, we have developed a new model that is based on the feedback information provided to the I/O subsystem controller. The presented model is applied to a multiple disk drive subsystem, which serves requests in parallel. Under conventional servicing, each ...

The performance of storage subsystems has not followed the rapid improvements in processors technology, despite the increased capacity and density in storage medium. Here, we introduce a new model based on the idea of enhancing the I/O subsystem controller capabilities by dynamic load balancing on a storage subsystem of multiple disk drives. The request servicing is modified such that each requ...

This paper examines the past achievements and current developments in space servicing, with a focus on enabling space robotics systems. As well, an attempt is made to predict future space servicing missions and applications that may help set the path for space robotic technologies development.

This study examines the interaction between external debt and economic growth, and analyses the sustainability of Nigeria’s foreign debt. Given the several reschedulings and persistent accumulation of the debt arrears, and consistently high debt burden ratios, it is doubtful if the debt burden can be judged as sustainable. This study employed analytical method and the findings from the analysis...

J.S. Neubauer 1 20 Annual AIAA/USU Conference on Small Satellites The vast foreseeable benefits of on-orbit servicing to current and future space systems have sparked the development of both large-scale servicing spacecraft and small-scale technology demonstration platforms. The latter provide the ability to prove certain crucial technologies more efficiently than their larger counterparts, due...
