The actual multi-agent system in a variety of complex network environment, the agent itself may be due to external attack led to the suspension of local exchange of information, The local information exchange between agents is also due to transmit and receive information associated with the communication time delay. In this paper, we study degree distribution entropy and the average two-step degree...
As new equipment development cycles are too long, there is an urgent need for comprehensive evaluation in the virtual prototype stage for equipment maintainability. This paper takes the characteristics of the design stage to construct a comprehensive evaluation index system, and puts forward subjective and objective weighting methods in a combination weighting method for an index of weights. Finally,...
In this study, we use an accelerometer sensor to measure human postural signals during a dynamic task. In previous studies, the step stability index (SSI) has been used to assess human balance via similar sensors. However, the placement of the 3 dimensional sensor differed, placed on the lower back of the subjects. To improve the detection method, we placed the accelerometer on the shoe. The purpose...
This study examined the fingertip force variability on the left and right hand during low-level sustained precision pinch with the thumb and index finger. Ten healthy, right-handed subjects were required to pinch a device with a stable force output at 5 N for 1 min. The pinch force was recorded for the right and left hand, separately. Visual feedback was provided for the first 30 s and removed for...
This paper presents an intelligent adaptive neurofuzzy inference system (ANFIS) based fuzzy Mamdani controller for a multifingered prosthetic hand. The objective of the controller is to move the finger joint angles along predetermined paths representing a grasping motion. The initiation of the grasping task is evaluated via EMG-entropy data, measured at the forearm of the prosthetic user. In addition...
Agent construction system is a new project management mode to meet the need of modern engineering construction, and is an innovation of government-invested engineering management mode. There are some positive aspects and some risks during the implementation .This paper analyses the risk factors based on the characteristics of agent management projects, establishes risk index system, using Entropy...
To be able to perform an analytical and more exact description of security, quantitative security measures are desirable. In this paper, we continue our investigation of the quantitative security measure guesswork, which gives the average number of guesses in an optimal brute force attack. The definition of guesswork is extended to joint and conditional guesswork. We show that joint guesswork is always...
Considering the complexity of the air and space integrated weapon equipment system, a multi-level hierarchical evaluation index system based on campaign capability is proposed using a multi-level fuzzy evaluation model based on grey correlation entropy is presented. In this model, by solving the grey incidence coefficients of the evaluation indexes, the weight of each index is determined by adopting...
In order to overcome the subjective randomness in traditional fuzzy comprehensive evaluation, the weight value is modified based on the differential degree of evaluation indices, a new model for comprehensive evaluation-entropy weight fuzzy comprehensive evaluation model is established by using the concept of entropy in information engineering science. Then the model is applied to the optimization...
Base on the traditional IHS (Intensity-Hue-Saturation) fusion and weighted IHS fusion algorithm, the adaptive weighted IHS information fusion based on local mean is discussed in this paper. Because the advantages and disadvantages of fusion algorithm have direct influences on the effect of remote sensing information fusion, the multiple attribute decision making method is proposed for assessing fusion...
