... in the form of a graph, whose nodes are the point sources of sound. We introduce edges in the graph, if the "distances" between two points are smaller than some critical value. The graph connectivity components characterize the attribution of micro seismo-acoustic events to clusters. The initial data...

... by higher-order gradients of the constitutive variables. The higher-order gradients are necessary for the convergence of numerical solutions of either continuum or discrete models (Aifantis 1984, 1987, 2012). Upstream Oil & Gas node zaiser consideration landslide Engineering mechanism real...

... for designing and verification of various types of constructions and rock bolts are no exception. Several special rock bolt elements were created for this purpose. The most widely used elements was presented in the work of Ömer Aydan (1988). The so-called Aydan element is represented by four nodes in its...

... level energy consumption. For displacement measurements a high resolution ultrasonic distance measurement device for long distances has been developed. The distance measurement between two nodes work up to 25 m and the accuracy of the determined displacement field will be in the range of cm. Typical...

... rings (whose diameter is around 0.42 m) confer outstanding mechanical properties to the net sheets and are used today in order to control rock fall trajectories. Such structures, composed of an array of metallic rings, are absolutely singular. A classic metallic net structure is composed of nodes...

... are connected to the rock masses. The number of nodes in the two-dimensional case is reduced to six. Swoboda & Marence(l992) modified the Aydari's formulation, assigning different coordinates for the bolt nodes and the nodes of rock-grout interfaces. Chen & Egger (l997) also developed a two dimensional...
