Research on Optical/Electric Hybrid Switching Technique for Space-Integrated-Ground Information Network by Shanghong ZHAO, Cong PENG, Yongjun LI, Hai LI

“…Space-integrated-ground information network will face the challenges of heterogeneous links, multi-granularity of information and limited resources in the process of networking.The problems can be solved by data switching design.The architecture of space-integrated-ground information network was described, and the present situation of multi-granularity service hybrid switching was analyzed.Based on this, the idea of hybrid optical/RF/packet switching was proposed, i.e., hybrid switching structure design, optical switching based on four-wave mixing eff ect, broadband confi gurable RF channelized switching, packet high-speed switching based on software radio idea, laser/RF heterogeneous link optical domain aggregation and grooming and enhanced general multi-protocol label switching design.…”

High-Speed GPU-Based Fully Three-Dimensional Diffuse Optical Tomographic System by Manob Jyoti Saikia, Rajan Kanhirodan, Ram Mohan Vasu

“…We have developed a graphics processor unit (GPU-) based high-speed fully 3D system for diffuse optical tomography (DOT). The reduction in execution time of 3D DOT algorithm, a severely ill-posed problem, is made possible through the use of (1) an algorithmic improvement that uses Broyden approach for updating the Jacobian matrix and thereby updating the parameter matrix and (2) the multinode multithreaded GPU and CUDA (Compute Unified Device Architecture) software architecture. …”

Novel Optical Coherence Tomography Parameters as Prognostic Factors for Stage 3 Epiretinal Membranes by Young Gun Park, Seo Yeon Hong, Young-Jung Roh

“…Central foveal thickness (CFT), EIFL thickness, and the length of the ellipsoid zone defect were evaluated at baseline and at 1 month, 6 months, and 12 months after surgery based on pre- and postoperative swept-source optical coherence tomography (OCT) images. The association of EIFL thickness and other OCT parameters with pre- and postoperative best-corrected visual acuity (BCVA) was analyzed. …”
