Waveform Characteristics of Tunnel Blast Waves and a Wave-Blocking Method by Xianshun Zhou, Xuemin Zhang, Tianhe Ren, Xuefeng Ou, Wenchao Xiong, Liming Zhang, Lei Zhang

“…Finally, it was found that a shorter distance from the NWBT to the source of the blast makes a better contribution to its wave-blocking effect. The waveform characteristics obtained in the study contribute to the design of tunnel surrounding structures; the application of the NWBT is a successful wave-blocking method for tunnels adjacent to environmentally sensitive areas.…”

COOPERATIVE BLOCK-PARALLEL ALGORITHMS FOR TASK EXECUTION ON MULTI-CORE SYSTEM by A. A. Prihozhy, O. N. Karasik

“…The problem of balancing the computational load among the cores of a multi­core system and increasing the efficiency of interaction among threads in a multi­thread application is considered. The cooperative block­parallel algorithms of solving complex tasks that can be decomposed into subtasks, which decrease the number of control transfers among threads, reduce the critical path length in a parallel implementation and increase the cores load are proposed.…”
