We present our complete study involving comparisons of three spatio-temporal filters used in the estimation of optical flow for continuous mobile robot navigation. Previous comparisons of optical flow and associated techniques have compared performance in terms of accuracy and/or efficiency, and only in isolation. These comparisons are inadequate for addressing applicability to continuous, real...

we solve the coupled mode equations governing the chalcogenide nonlinear fiber bragg gratings (fbgs) numerically, and obtain the bistability characteristics. the characteristics of the chalcogenide nonlinear fbgs such as: switching threshold intensity, bistability interval, on-off switching ratio are studied. the effects of fbg length and its third order nonlinear refractive index on fbg charac...

Emerging optical networks will provide very high bandwidth connections to users. However, improving provisioning times and restoration capabilities after a network failure are important issues in evolving the optical networks. The application of IP-based protocols to the optical network control plane has opened up new opportunities and challenges for network designers. Although much work has be...

The Industrial Ethernet based on IP realizes interconnection of industrial network and information network, and it is the most potential technology in the new industrial net products. In this paper, the defects of the original control system for tobacco shred production line are analyzed, and the new design plan of control system based on EtherNet/IP is presented. The control net adopts redunda...

In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...

Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high bandwidth, low latency, and power consumption. We propose demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control which is suitable for HPC infrastructures. also present an Optimized Mapping (OPM) algorithm that maps the most communication-related processes inside rack....
