Definition Of

A new method for community identification is proposed which is founded on the analysis of successive neighborhoods, reached through hierarchical growth from a starting vertex, and on the definition of communities as a subgraph whose number of inner connections is larger than outer connections. In order to determine the precision and speed of the method, it is compared with one of the most popular community identification approaches, namely Girvan and Newman's algorithm. Although the hierarchical growth method is not as precise as Girvan and Newman's method, it is potentially faster than most community finding algorithms.

Based on the current contradiction between the grammar-translation method and the communicative teaching method in English teaching, this paper, starting with clarifying the task of comprehensive English as well as the definition of the two teaching methods, objectively analyzes their advantages and disadvantages and proposes establishing a new method by fusing them with an elaboration on the reasonability of combining them in the practical teaching of comprehensive English with their complementary advantages.

Evaluation method of reliability parameter estimation needs to be improved effectively with the advance of science and technology. This paper develops a new method of parameter estimation, which is named E-Bayesian estimation method. In the case one hyper-parameter, the definition of E-Bayesian estimation of the failure probability is provided, moreover, the formulas of E-Bayesian estimation and hierarchical Bayesian estimation, and the property of E-Bayesian estimation of the failure probability are also provided. Finally, calculation on practical problems shows that the provided method is feasible and easy to perform.

More than thirty years after its publication The Roman Revolution still stands unrivalled, not as the ‘definitive’ account of the emergence of a monarch from the ruins of the Republic but as something far more than that, the demonstration of a new method in the presentation of historical change. The aspect of this method, which has found most imitation, is of course prosopography; and it is indeed essential to it. But far more important is the use made of contemporary literature to mirror events, and to analyse and define the concepts and the terms in which the events were seen by those who lived through them.It is the common characteristic, perhaps even the definition, of great works of history that they invite imitation and offer a challenge, not just to apply their methods and standards to other areas, but to pursue their own conclusions further. The present paper is gratefully offered as an attempt to portray with a different emphasis some aspects of the establishment of Octavian as a monarch, first by demonstrating the extent to which the institutions of the res publica remained active in the Triumviral period, and secondly by redefining the change which culminated in 27 B.C., precisely by asking again in what terms it and the novus status which emerged from it were seen by contemporaries.

Abstract On the basis of rough set theory, the strengths of dynamic reduction are elaborated compared with traditional non-dynamic methods. A systematic concept of dynamic reduction from sampling process to the generation of the reduct set is presented. A new method of sampling is created to avoid the defects of being too subjective. And in order to deal with the over-sized time consuming problem in traditional dynamic reduction process, a quick algorithm is proposed within the constraint conditions. We have also proved that dynamic core possesses the essential characteristics of a reduction core on the basis of the formalized definition of the multi-layered dynamic core.

Definition Of

This paper proposes a systematic procedure to identify river reaches from a geomorphic point of view. Their identification traditionally relies on a subjective synthesis of multi-dimensional information (e.g., changes of slope, changes of width of valley bottom). We point out that some of the attributes adopted to describe geomorphic characters of a river (in particular sinuosity and confinement) depend on the length of reaches, while these latter are not yet identified; this is a source of ambiguity and introduces, at least conceptually, an unpleasant, implicit, iterative procedure. We introduce a new method which avoids this difficulty. Furthermore, it is simple, objective, and explicitly defined, and as such, it is automatable. The method requires to define and determine a set of intensive attributes, i.e., attributes that are independent of the segment length. The reaches are then identified by the intersection of the segmentations induced by such attributes. We applied the proposed procedure in two case studies, the Magdalena River (Colombia) and the Baker River (Chile), and investigated whether the adoption of the traditional approach for the definition of reaches would lead to a different result. We conclude that there would be no detectable differences. As such, the method can be considered an improvement in geomorphic river characterization.

Abstract This paper describes a new method of determining the reactive power factor. The reactive power factor herein is calculated on the basis of time samples and not] with the Fourier transform of signals, like it was done previously. The new reactive power factor calculation results from the receiver admittance-operator decomposition into the product of self-adjoint and unitary operators. This is an alternative decomposition to another one, namely into a sum of the Hermitian and skew-Hemiitian operators.

Coupling method is developed in recent years to solve numerical problems a new method, meshless - the finite element of a direct coupling method is based on the definition of the generalized unit of coupling of the new method . The core of this method is the use of each unit in the shape function to the assumption that the brain that the whole sub-domain to be seeking to solve the unknown field function. Coupling with other compared with the method is simple to calculate the advantages of a short time.

Today special education has been developing all over the world as it is in our country and renews itself with new method and techniques. In my opinion an errorless person has never worked or has worked little. In this study after document scanning aiming data collection, a short definition of gifted and autistic children was done as well as their characteristics were given. The problems encountered in defining and diagnosing, persuasion dimension of parents regarding this subject with its similar and different aspects were shortly mentioned. Again in this study teaching methods of these children and the points to consider were mentioned without ruling out any point.  The study was finished by giving results and discussion sections.Keywords: gifted, autism, diagnosing of gifted ones
