An essential aspect of stock trading is the accurate forecast of stock price. This enables buy and sell points to be determined, which facilities profitability whilst reducing potential loses. This paper proposes a "Two-stage pattern Strategy (TSPS)" as an effective and intuitive mechanism to identify...

The problem of maximum and minimum on the difference between the product of two events' probability and the probability of product of two events has been discussed, in this paper, two events are generalized to n events and the problem is solved by using the method of induction and construction.

Proper orthogonal decomposition four-dimensional Variational (POD 4D VAR) data assimilation method is used to estimate the open boundary conditions (OBCs) with a two-dimensional (2D) M2 tide in the Bohai Sea by assimilating the TOPEX/Poseidon (T/P) altimeter data. Qian et al. [14] assume that the OBCs...

A novel multiple watermarking scheme was proposed, which could embed the reversible watermark in ROI (region of interest) by improving the Ni's algorithm, and the robust watermark in non-ROI by quantizing the low frequency coefficients. The watermarks can simultaneously achieve copyright protection and...

In this study, a distributed cooperative control law is proposed to attain multi-agent uniform circumnavigation around moving targets. First, we construct a decentralized estimator for each agent to estimate the geometric center of the targets. Then, we develop the distributed control strategy by means...

For the differential game about the pollution emissions control problem among countries, we apply Shapley value to allocate the total payoff of all countries. The important contribution of this paper is the establishment of a time-consistent imputation distribution procedure so that the initial agreement...

The research aims to generate a sparse graph for travelling salesman problem so as to reduce its complexity. A probability model based on frequency quadrilaterals is given to show that the average frequency of an edge is 3N if its total frequency is computed with N random frequency quadrilaterals in...

The problem of propositional satisfiability (SAT) has found a number of applications in both theoretical and practical computer science. However, in many applications, knowing a formulae's satisfiability alone is not enough to solve problems. Often, some other characteristics of formulae need to be known....

We present a method for verifying the contact stress of elastic bodies. An explicit formulation of the total contact force, a fraction function with the numerator as a linear function and the denominator as a quadratic convex function, is derived by using the surrogate model of quadratic optimization...

Particle pollutant is the prime pollutant of most cities in china, the tiny particle accumulated lots of harmful substance, and it is the carrier of bacteria, revealing the Mechanism of particle transport has an important meaning on controlling the indoor particle pollutant and disease prevention. This...

Mining important persons is significant to network security, especially researches on email network centralization nowadays. To solve the problem that traditional PageRank algorithm is sensitive to the network disturbance, this paper proposes a method which decomposes email network into different layers...

In this paper, we consider a n-species stochastic Lotka-Volterra competitive system with distributed delays. Sufficient conditions for stability in the mean and extinction of each population are established.

Most countries adopt film rating system for protect their children from bad content. But there are often disagree with the rating results because of subjective judging system. This study tried to develop evaluation algorithm for film rating using human response data like EEG and eye movement. Eye-tracking...

Enterprise value assessment is a hotspot of research on modern financial problems; profound changes have taken place in China's stock market system and investment environment, in the direction of more fair, effective and standardized development, Chinese stock market is more and more showing the intrinsic...

This study suggests new mathematical solution and simulation results for detection location of bus signal priority. This mathematical model can determine the detector location for the minimum bus delay. With the application of the bus speed and detector location, this study analyzed the change of bus...

Research on bauxite digesting using pressurized reactor at a capacity of 86,66 kg of feed/batch had been conducted. Bauxite with -150 mesh of particle size is reacted with 42,15 kg of caustic soda with concentration of 433,49 g/l at the temperature of 140oC for 1.0 to 2.5 hours using steam as heating...

ARP protocol is one of the basic agreement in TCP/IP network protocol, but ARP protocol is not safe, because it does not verify the source of the ARP packet is legal or not, in this case lead to variety ARP attack in the local area network (LAN) with the lack of authentication mechanism in ARP protocol,...

This paper explores the multiplicity of solutions for a Certain class of fractional elliptic equation under the Dirichlet boundary conditions. By using the asymptotic property of the nonlinear term f(x,u) at zero and at infinite point, the mountain pass theorem and proper truncation methods can be applied...

We construct an evaluation system of sustainable development countries using the method of Bayes, k-means. Based on the classification, the developing model can be categorized into self-sufficient, technology-dependent and fund-dependent countries. We also explores the sustainable development of Equatorial...

Under carbon cap-and-trade policies, double-source purchase policy of two substitutable products by a monopoly retailer is studied, obtaining optimal purchase decision and optimal pricing decision of retailers. Firstly, optimal decisions of retailers under carbon-free constraints and carbon cap-and-trade...
