The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists th...

The work presented in this thesis belongs to the computer music field as well as to the virtual reality field. First, we describe the advantages of immersive virtual environments and of 3D graphical interaction for multiprocess instruments and particularly for the hierarchical live-looping, a new instrument model that we define. We then suggest solutions to visualize and manipulate sound proces...

To make large-scale distributed systems practical for a broader user base, we are investigating a high-level framework to support and aid the development of reactive distributed applications. The reactive object framework offers large-scale distributed applications the ability to automatically adapt to the state of the distributed system as well as the behavior of the application. The system au...

The success of LCLS has opened up a new era of x-ray sciences. An upgrade to LCLS is currently being planned to enhance its capabilities. In this paper we study the feasibility of using the echo-enabled harmonic generation (EEHG) technique to generate narrow bandwidth soft x-ray radiation in the proposed LCLS-II soft x-ray beam line. We focus on the conceptual design, the technical implementati...

Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. The main classes of routing protocols are Proactive, Reactive and Hybrid. A Reactive (on-demand) r...
