Stability Assessment of Rock Slopes in the Former Quarry of Wojciech Bednarski Park in Kraków—A Case Study

open access: yesApplied Sciences
This study presents a stability assessment of rock slopes, considering the joint systems of the rock walls of Wojciech Bednarski Park. Special emphasis was placed on analysing the orientation and infill characteristics of the identified joint sets. Based

Panarchy: Discontinuities Reveal Similarities in the Dynamic System Structure of Ecological and Social Systems

open access: yesEcology and Society, 2009
In this paper, we review the empirical evidence of discontinuous distributions in complex systems within the context of panarchy theory and discuss the significance of discontinuities for understanding emergent properties such as resilience.

Convergence of the Discontinuous Galerkin Method for Discontinuous Solutions [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2005
The author proves convergence of a discontinuous Galerkin method for a convection-reaction equation under very weak assumptions on the coefficients. The proof is based on work of \textit{R. J. DiPerna} and \textit{P. L. Lions} [Invent. Math. 98, 511--547 (1989; Zbl 0696.34049)]. Applications include modeling the flow of incompressible immiscible fluids.

Explosive synchronization is discontinuous [PDF]

open access: yesPhysical Review E, 2015
Spontaneous explosive is an abrupt transition to collective behavior taking place in heterogeneous networks when the frequencies of the nodes are positively correlated to the node degree. This explosive transition was conjectured to be discontinuous. Indeed, numerical investigations reveal a hysteresis behavior associated with the transition.

DISCONTINUITY OF KNOWLEGDE

open access: yesBeykent Üniversitesi Sosyal Bilimler Dergisi, 2017
M. Foucault and T. Kuhn concerned with the discontinuity of discourse in the sciences and social disciplines. In 1960s Kuhn stated that the natural science reflects basically a sequence of paradigm changes. In 1970s Foucault claimed a form of discourse about the growth of scientific knowledge in a range of human and medical sciences.

Characterization of Complex Rock Mass Discontinuities from LiDAR Point Clouds

open access: yesRemote Sensing
The distribution and development of rock mass discontinuities in 3D space control the deformation and failure characteristics of the rock mass, which in turn affect the strength, permeability, and stability of rock masses.

利用地震光照成像法研究青藏高原东南缘岩石圈间断面结构及其动力学意义

open access: yesDizhen xuebao, 2019
为了进一步认识青藏高原东南缘的构造演化等动力学问题以及该区域的深部孕震机理,本文使用位于该区域内的中国地震科学台阵探测项目的台站所记录到的远震P波波形数据,采用地震光照成像法获取了岩石圈间断面的结构,并讨论了该方法的准确性和稳定性。研究结果显示,青藏高原东南缘的岩石圈西薄东厚,其中:滇缅泰地块腾冲火山附近最薄,约为60 km,其较薄的岩石圈可能是软流圈地幔物质上涌造成的;扬子地块岩石圈厚度从四川盆地向南逐渐减薄,特别是四川盆地下方最厚,可达190 km左右;滇缅泰地块腾冲火山下方150 ...
