Descriptive numbers (parameters) can be attributed to every emission event.
The basic means of description is the number of emission events per a period of time.
It is assumed that the number of AE events corresponds to the number of microcracks that form inside of the material but no knowledge is available as to their orientation.
Fig. 3 shows the number of AE events recorded during the Ec test.
A smaller number of events and by extension microcracks is probably indicative of less solid bonds in the material’s matrix.

This crack initiation is typical for the VHCF regime and is linked to a crack initiation mechanism which forms a fine grained area (so called FGA) that occurs at inclusions at which the stress intensity factors are below the threshold value of long cracks [1].
Consequently different threshold values of stress intensity factors can be derived regarding a failure at numbers of cycles lower than the ultimate number of cycles of 109.
This process takes more number of cycles for the crack initiation than in the case of TiN inclusions.
Restressed runout specimens failing from TiN inclusions lead to a number of cycles to failure in the regime of the ultimate number of cycles.
These different crack initiation mechanisms result in different threshold values of stress intensity factors for the different inclusions types if a failure at numbers of cycles lower than the ultimate number of cycles of 109 is considered.

It is defined as the sum of the number of discontinuities per meter in perpendicular direction for each joint set: (1) where N is the number of discontinuities and L is the length of the scan-line in a perpendicular direction for each joint set present (1, 2, 3, …).
Dn is estimated by counting the number of surfaces of natural rock blocks.
It is medium grained, with two micas (muscovite > biotite) and presents a high degree of weathering, with a characteristic yellowish brown colour that can be extremely variable (Fig. 2).
Fig. 4 - Distributions of the mean joint spacing (S) and median joint spacing (Smed) of the studied places (number of data: 30).
A large number of the exploitation places do not have the minimum conditions for extracting large blocks.

There are several methods of measuring the fractal dimension which include changing coarse graining level, such as selfresemble dimension, Hausdorff dimension, box-counting dimension, correlation dimension, information dimension and so on.
Then, counts the numbers of units (smallest squares) in the grid that have intersect with the orbit.
The number is stored in a variable namely )(mN .
The shaft centre orbit In SGA, it is key to count accurately the number of the units that intersect with the orbit.
Finally, the sum of all elements in the matrix is the number of units that have intersections with the orbit.

Alternative classification techniques consider only structure of the XML document. [5,6] treat XML documents as labeled trees, and the measurement of similarity between two XML documents is produced by computing the edit distances between two trees. [7] introduce a structure graph to measure similarity, whose similarity measure is loose-grained.
Next, if the frequency of occurrence for keyword k in element node j is , then the weighted frequency for keyword k is computed as Eq. 2; Finally, according to Eq. 1 and Eq. 2, the total weight of textual keyword k in document d can be computed as Eq. 3: (2)　　 　　 (3) where, n is the number of leaf element nodes containing keyword k in document d，N is the number of documents in document set, nk is the number of document containing the keyword k.
(2) The number of categories is only two.
For a given category, recall is the ratio of the number of correctly classified documents in the category to the total number of documents from this category.
Precision is the ratio of the number of correctly classified retrieved in the category to the total number of documents assigned to this category.

Most monomers employed, however, can rarely enter into wood cell wall to react with hydroxyl groups and just polymerize in wood cell lumen without grafting with wood matrix, which results in weak chemical combination between the two phases and large numbers of hydroxyl groups still available.
The end grain of sample was cut with a surgical blade and the sample was mounted on sample holder with a double-sided adhesive tape, gold sputter-coated.
Figure 2 also shows that the peak of the modified wood at 1733cm-1 for carbonyl stretching vibration is enhanced as compared to the corresponding untreated wood, indicating the number increasing of carbonyl groups in wood components.
According to the reaction mechanism, it is reasonably believed that the increasing numbers of carbonyl groups should be attributed to the reaction of wood components with GMA/EGDMA.

Introduction Amorphous hydrogenated carbon (a-C:H) is a technologically very interesting material with a number of potential industrial applications, including razor blades, automotive components, critical engine parts, mechanical face seals, scratch - resistant glasses and micro-electromechanical systems [1]-[3].
The gas is fed in to the deposition chamber through this tube, uniformly dispersed by the holes between the grains of sintered powder, which acts as a sieve.
Magnetic field is used to confine electrons in the plasma and by doing so to increase the number of ionizing collisions between electrons and neutral atoms in the plasma.

Microscopic observations of the material exhibited the same structure of the steel in both perpendicular directions (longitudinal and transversal), i.e. ferrite with carbides arranged on borders and inside grains.
Numbers 1, 2, 3, 4 denote magnitudes of cyclic strain amplitude: ±0.1%, ±0.2%, ±0.4% and ±0.8%, respectively.
An interesting feature can be observed when hysteresis loops of the same number at each block of cycles are compared, Figs. 3, 4.
