The potential of waste brewer's yeast(WBY) used as bio-adsorbent to adsorb BasicGreen(BG) was investigated in this paper. Adsorption of BG was pH-dependent and the optimum pH for cation dye is 5.0 . Kinetic process of Basic Green adsorbed by waste brewery's yeast can well described by pseudo-second-order models. With the increase of initial dye concentration, the adsorption quantity increased and...
When we consider risk as a type of financial asset, and accordingly transform the measurement of risk into the pricing of asset (i.e. risk), a series of assets pricing methods in financial economics can be applied. Furthermore, Equilibrium Pricing Principle has proved the rationality and feasibility of this consideration, and points out that traditional risk measurement method, VaR (Value at Risk)...
In this paper, we investigate how agents' value expectation to fiat money influence circulation of fiat. We use both replicator dynamics and multi-agent simulation to describe how rational agents shift their strategies and gradually accept fiat in the transactions. We find that higher value expectation and more specialization in social production make fiat widely accepted easier. This paper present...
In this paper, fuzzy comprehensive evaluation and Matlab combining method is applied to the assessment of cadres, the first divided into four categories based on attributes in each category was divided into four categories, first in the various factors in the implementation of a single judge, and then together to implement a secondary evaluation, and finally given the realization of the Matlab model...
Taking Excel as the development platform, one offshore wind turbine foundation monitoring system software is developed merging two excellent analysis softwares, namely FlexPDE expert in multi-physics coupling simulation and ANSYS expert in structural analysis and display features. They are integrated together, the influence of seabed instability on the pile response could be considered, so the pile...
Growth rate of abdominal aortic aneurysm (AAA) is thought to be an important indicator of the potential risk of rupture. Wall stress is also thought to be a trigger for its rupture. However, stress change during the expansion of an AAA is unclear. Forty-four patients with AAAs were included in this longitudinal follow-up study. They were assessed by serial abdominal ultrasonography and computerized...
In this paper, theories of Chi-square test of multinomial distribution and contingency table analysis, and their applications in customer satisfaction are introduced, and empirical analyses are carried out.
In this paper, partial least squares regression is introduced. And the modeling steps and the realization of the modeling algorithm for building a PLSR2 model are given. Moreover, a numerical example is presented.
China is one of the countries in the world that suffer serious natural disasters. Frequent and serious biological disasters cause great damage to crop production. The plant disease data of multiform could be analyzed and then a forecasting report was made.This article according to characteristic of the plant disease, introduced forecasts system's design and key technologies realization based on data...
The linear structural equation model is introduced in this paper. And as an example of the linear structural equation model, a new customer satisfaction indices model is built, Sas procedure for parameter estimation is given, and the model is fitted by using sampling data and the results are evaluated.
A biometric system usually contains two stages: registration and authentication. Most biometric systems capture multiple samples of the same biometric trait at registration. As a result, it is essential to select several samples as templates. This paper proposes two algorithms maximum match scores (MMS) and greedy maximum match scores (GMMS) based on match scores for template selection and update...
Through coordinate segregation of barycenter moving track of urban cluster, a complex function composed of one trend item and several cycle items is adopted to simulate the change of barycenter??s x-,y-coordinates. And GA is used to estimate the model parameters. It needn??t linearize the model in advance. The methods above can arrive at a satisfactory result on barycenter-moving track of Shandong...
The method of using genetic algorithm to estimate parameters of natural disaster predicting model is given. Two long-term predicting models of agricultural area suffering from natural disaster are set up by using this method in Shandong Province. The models include one and two periodic components respectively. The research shows that genetic algorithm can be used to estimate parameters of complex...
A biometric identification procedure usually contains two stages: registration and authentication. Most biometric systems capture multiple samples of the same biometric trait (e.g., eight impressions of a person??s left index finger) at the stage of registration. As a result, it is essential to select several samples as templates. This paper proposes two algorithms maximum match scores (MMS) and greedy...
According to the chaotic and non-linear characters of power load data, the model of artificial neural networks ANN based on Lyapunov exponents was established. The time series matrix was established according to the theory of phase-space reconstruction, and then Lyapunov exponents was computed to determine time delay and embedding dimension. Then artificial neural networks algorithm was used to predict...
