The influencing factors indexes system of food industrial enterprises' integrity & credit is constructed from enterprise, government, market, society and consumer. It is difficult to decide accurately which factor has the greatest influence and influenced degree on the integrity & credit because there are the complicated, interactive and restrictive influencing relations between each pair...
This paper mainly studies one dimensional mean-field backward stochastic differential equations (MFBSDEs) when their coefficient g is uniformly continuous in (y′, y, z), independent of z′ and non-decreasing in y′. The existence of the solution of this kind MFBSDEs has been well studied. The uniqueness of the solution of MFBSDE is proved when g is also independent of y. Moreover, MFBSDE with coefficient...
Rapid and accurate fault detection and diagnosis (FDD) is gaining importance for complex equipments because of the need to increase reliability and to decrease possible loss. In this paper, an intelligent fault diagnosis method is presented by using case-based reasoning (CBR) methodology to infer and classify various failures. Firstly, the case representation and the case base are established according...
This paper focuses on integral sliding mode output control for linear delta operator systems with insensitivity to sampling time jitter in the case of small sampling times along with unmatched disturbances. A delta-domain integral sliding mode sector can be reached without chattering by employing a novel reaching law to avoid the inherent numerical ill-condition resulting from using the traditional...
By introducing the fractional-order difference into the updating formulas of the velocity and position, fractional-order particle swarm optimization algorithm is proposed. The effects on the convergence rate and accuracy are analyzed, by introducing fractional-orders in the updating formulas for the velocity and position. Moreover, the linear increasing methods to adjust the fractional-orders are...
This paper applied the factor analysis method to dynamically evaluate the credit risk of listed companies in China. Sixteen measurable indicators which can reflect the public credits of listed companies are selected and 4 main indicators are extracted by applying the factor analysis method. On the basis of it, 16 sub-indicators are further given to explain the affecting level to the credit of listed...
It is worse that steam generator is controlled by PID which is non-minimum system with oscillation. ADRC achieves excellent control performance using nonlinear control law, but it isn't necessarily optimal when adopting standard ADRC structure and NLSEF. In this paper, we optimize the standard ADRC, the simplified ADRC without TD, the improved ADRC with NLSEF using mtfal and zzxfal based on GA. The...
Towards the situation that the traditional fractional difference always has the same order in various regions of image for image processing, this paper presents a novel approach that the fractional order is automatically adjusted according to the gradient of every image pixels. The main contribution of this work is that Otsu algorithm is used to design the adaptive image enhancement operator, and...
This paper is concerned with the evaluation model of emergency capability evaluation for the ship at sea. The goal of our work is to find the human reasons leading to the poor ship emergency capability, and then improve the team cooperation ability in emergency to avoid the vessel accidents. In this paper, firstly, according to the special attitude of the ship on sailing, the emergency capability...
The evaluation of the city public emergency capability is an important basis of the development of the city emergency capability. This paper made a evaluation to the eight sample cities based on the Fuzzy Set Theory. And the sample cities are choice by the three criteria such as disaster distribution, city type and geography location and so on. And they are Nanning, Harbin, Yinchuan, Shenyang, Jinan,...
This paper studies optimal control designs for networked linear discrete-time systems with quantization effects and/or fading channel. The quantization errors and/or fading channels are modeled as multiplicative noises. The H2 optimal control in mean-square sense is formulated. The necessary and sufficient condition to the existence of the mean-square stabilizing solution to a modified algebraic Riccati...
It's common practice for patients to make an appointment in advance before seeing the doctor. This paper compares two alternative policies to reduce no-show for single server appointment system with exponentially distributed service time, the overbooking policy and open access policy. A specified number of patients call for an appointment before the scheduled day, but may cancel the booking or don't...
The general singular Boolean networks (SBNs) are proposed in this paper according to the algebraic form of dynamic-algebraic Boolean networks. First, the solvability theorems of this kind SBNs are presented. Then, the transition matrix of an SBN is defined, based on which the results on fixed points and cycles of SBNs are obtained. Furthermore, general singular Boolean control networks (SBCNs) are...

Aming at the current problem that Electronic whiteboard positioning has the poor accuracy, we propose an improved UKF positioning algorithm. Through adding time-varying fading factor to the standard UKF algorithm, such method can significantly reduce the influence of outmoded data on the current estimation value. Meanwhile, by adding adaptive adjustment factor to alter filtering gain to control the...

The T-S fuzzy optimization algorithm is applied in the weighted coefficients of roll and yaw in this paper. According to the closed-loop gain shaping algorithm, robust PID controllers to roll and yaw are designed and then they are...
Integration of data from heterogeneous data sources is one of several technical challenges during the tunnel construction. BIM and relational database have maken their efforts for tunnel data organization, but they are not qualified for tunnel problem reasoning. This paper proposes a tunnel data organization method driven by Ontology, which is suitable for data reorganization as well as reasoning...
Higher standards have been placed on the flexibility and accuracy of characteristic detection methods of voltage flicker characteristics due to sporadic flicker disturbances. S-transform as a tool of signal analysis has been limited in practical application because of the fixed shape of its Gaussian window function. Some existing modified S-transform algorithms have demonstrated increased adaptability...
