This paper presents the design considerations of a project to develop a real-time, secure operating system for parallel, heterogeneous processing systems. The system will support software technologies required to develop and effectively use secure scalable and distributed high performance computing technologies. Examples of target technologies include(More)
The robots operating in hazardous environments such as nuclear plant decommissioning or terrorist bomb disposal need to show off-road capabilities due to the uneven terrain including stairs and ditches. The hazardous environment operation typically requires the use of a remotely operated robot. In this paper we propose an improved articulated track(More)
Vibration is a key factor to be considered when designing the mechanical components of a high precision and high speed atomic force microscope (AFM). It is required to design the mechanical components so that they have resonant frequencies higher than the external and internal vibration frequencies. In this work, the mechanical vibration in a conventional(More)
In NGN, many transport-related technologies were considered. One technology discussed is ATM (Asynchronous Transfer Mode) based MPLS (Multi-protocol Label Switching) for its provisioning QOS (Quality Of Service) commitment, traffic management aspects and smooth migration to the BcN in Korea. In this paper, we present preventive congestion control mechanism(More)
A major goal of the BcN (Broadband Convergence Network) is to facilitate convergence of networks and services. Many transport-related technologies were considered. One technology discussed is ATM (Asynchronous Transfer Mode) based MPLS (Multi-protocol Label Switching) for its provisioning QOS (Quality Of Service) commitment, traffic management aspects and(More)
