Health Signal Generation in the ORCA (Organic Robot Control Architecture) Framework

ORCA - Towards an Organic Robotic Control Architecture

A Retrospective on ORCA: Open Resource Control Architecture

ORCA is an extensible platform for building infrastructure servers based on a foundational leasing abstraction. These servers include Aggregate Managers for diverse resource providers and stateful controllers for dynamic slices. ORCA also defines a brokering architecture and control framework to link these servers together into a federated multi-domain deployment. This chapter reviews the archi...

High Speed Delay-Locked Loop for Multiple Clock Phase Generation

In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...

Robot control system using SMR signals detection

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

At-scale experimentation with resource virtualization in a metro optical testbed

In this paper we describe several efforts to explore integrated approaches to resource virtualization in a metro-scale optical testbed dubbed BEN (Breakable Experimental Network) located in Research Triangle Park, NC. The first one is an extension of work done at Duke on the ORCA (Open Resource Control Architecture) framework. The effort between RENCI and Duke seeks to expand the scope ORCA to ...
