Space-time evolution rules study on acoustic emission location in rock under cyclic loading

Jiang XU, Shuchun LI, Yunqi TAO, Yongdong JIANG, Xiaojun TANG,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 4,   Pages 422-427 doi: 10.1007/s11709-009-0056-8

Abstract: An acoustic emission (AE) location experiment was performed on sandstone using an advanced AE test system, and the location points changed slowly.There was a modest increase of location points in every cycle.The tendency of steady development could be predicted from the AE location events.Location events changed quite rapidly and assembled and linked continuously in the core zone.

Microseismic monitoring of Well J-253 in complicated construction

Zhao Xinhong,Che Hang,Luo Jiong

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 12-15

Abstract:

Well J-253 is located in the J-11 fault block of North China oil field. The direction and geometry size of hydraulic fracture are affected by the stress, geological structure and faults, as well as hydraulic sand blasting. The direction of the initial artifical fracture is at NNE, deviating from the direction of the maximum herizontal principal stress. Then it turns to the direction of the maximum horizontal principal stress and normal direction of contour. Moreover, there are significant fissures lined around the well. It has typical significance to study the artifical fracture direction and geometry of Well J-253.

Network-based optimization techniques for wind farm location decisions

Jorge Ignacio CISNEROS-SALDANA, Seyedmohammadhossein HOSSEINIAN, Sergiy BUTENKO

Frontiers of Engineering Management 2018, Volume 5, Issue 4,   Pages 533-540 doi: 10.15302/J-FEM-2018025

Abstract:

This study aims to find appropriate locations for wind farms that can maximize the overall energy output while controlling the effects of wind speed variability. High wind speeds are required to obtain the maximum possible power output of a wind farm. However, balancing the wind energy supplies over time by selecting diverse locations is necessary. These issues are addressed using network-based models. Hence, actual wind speed data are utilized to demonstrate the advantages of the proposed approach.
