Let G be a graph where for each vertex, a subset of a set of K colors is assigned. If for each vertex to which an empty set is assigned, its neighborhood contains all K colors, then such an assignment is called a K-rainbow dominating function of G. The corresponding invariant rrk(G), which is the minimum...

Support vector regression machine is suitable for small sample decision and it is good to data forecasting capabilities. Its nature of learning method is under the condition of limited information to obtain a good ability in data mining. Accurate electricity load forecasting is an important practical...

All kinds of image retargeting algorithms based on seam carving are the representative types of discrete resizing methods. Seam carving algorithm refers to delete or insert pixel lines to resize image’s technique. Pixel line pass through the whole image horizontally or vertically, deleting the pixel...

This paper focuses on dynamic pricing decision with a static reference price in revenue management situations. Firstly, it constructs the optimal control model with continuous time and continuous prices. Secondly, it defines the concept of multiplicative reference effect, and describes the characteristics...

In this paper we tried to perform a classification of modern decision support systems, applied in the oil industry, the methods and approaches implemented, the tasks and problems to be decided by the oil and gas production operators, applying these methods.

Electrical capacitance tomography (ECT) is a relatively mature non-invasively imaging technique that attempts to map dielectric permittivity of materials. Recently, 3D ECT has gained interest because of its potential to generate volumetric images. In this paper, two kinds of 3D capacitance imaging sensors...

Along with the accumulation of earthquake damage experience and researches on earthquake, the standard of building seismic design is modified all the time to be more objectively and scientifically. The soil-structure interaction method is significant but still qualitative, so a detailed comparison between...

According to cost and customer satisfaction degree, we build a bi-objective maximal covering problem in order to study the influence of central station siting by cost and customer satisfaction degree. During solving this bi-objective maximal covering problem, we use the normalized normal constraint method...

The rapid increase of transportation makes it necessary construct shallow burial Tunnel under skew-crossing highway in China. Thus, the prediction of the influence on the safe operation of skew-crossing highway in the tunnel construction plays a key role in the optimal design and construction of tunnels,...

Using data mining technology to transformer operation analysis of the defects in the process of data mining, mainly for the entire network analysis of the defect data transformer account, defects, fault, environment and other information. Analysis mainly from the state information of equipment, equipment...
