We present an overview of neural network approaches for efficient modeling, simulation and optimization of high-frequency electronic and microwave circuits. Neural networks trained from electronic/microwave data are subsequently used for circuit simulation and optimization. A brief introduction of the...

In the past few years, the automotive electronics and sensing technologies have developed rapidly. Today, the status of most of the sub-systems in a running vehicle can be accurately monitored. This process produces a huge amount of data. Extracting the potential value of such data, to for instance support...

Many physical phenomena can be modeled as the propagation of sound or radio waves, the fluids flow, the dis-tribution of gas, the dispersion produced in a river, etc. With the help of the AC we can deduce very realistic situations. In previous work, we simulated the propagation of sound in the city using...

In the paper we describe a software developed to simulate the complexes of the surface infrastructure of oil and gas fields. The created software is based on methods and algorithms proposed by the team of authors for constructing models of surface equipment for hydrocarbon deposits. The proposed approaches...

First, this paper establishes a three-dimension simulation model of the planar 3-dof parallel mechanism, and realized its kinematics simulation;Second, the velocity and acceleration curves of the mechanism are simulated by differential method and influence coefficient method, and the Singular configuration...

Representational redescription is an important theory which describes conceptualization as an implicit to explicit process. This paper analyzed stages in the description in two dimensions on structural formation and generalization respectively. Focus on the structural formation dimension, this paper...

In the paper we describe a new approach to the construction of a model, applied for a complex for the extraction and processing of hydrocarbon raw materials. The basis of the model is a group of independently functioning components, organized on the basis of modern Arificial Intelligence methods, including...

This paper discusses a case-based approach to teaching process control involving modeling, measuring, PID and cascade control methods. In the traditional process control teaching, there are some problems such as knowledge points are taught without any example or taught by different examples. which make...

As a child frame of Hibernate framework, Hibernate shards provides an effective implementation scheme for the database slicing technology developed by SaaS, expands the shared database and sharing mode, and the program development, deployment and implementation are similar to Hibernate, At present also...

Data prefetching has been widely used in modern cache subsystems. Actually, an aggressive prefetching may bring negative yields unexpectedly, in which a new proposed prefetching strategy normally needs to be evaluated before being applied in the real design. In the last decade, prior researchers prefer...

The basic law and method of Hilbert-Huang Transformation (HHT) is introduced, and HHT is induced into the application study of dynamic EEG data under +Gz acceleration. The dynamic EEG data at static state that is when 1G and under +Gz acceleration is made time frequency analysis by using HHT method,...

Compared with the others data, scientific and technical literature is multi-source and multiple types. Its content is more emphasis on technical and correlation. In order to analyze and evaluate it, the paper got the value of correlation based on VSM. And it introduced the value of correlation into evaluation...

It is recommended to monitor the time between events(TBE) when the defect rate is very low. An unbiased median chart is proposed to monitor exponential distributed TBE data and some design parameters are provided for ease of application. For the parameter is usually unknown, the effects of estimation...

The recommended algorithm is one of the most popular applications of today. Firstly, the original data is cleaned and processed, and then the association rules model and user value analysis model are established in this paper. Secondly, a Apriori algorithm is used to analyze the relationship between...

With the development of GPU's general computing power, hybrid systems composed of multi-core CPU and GPU are becoming more and more popular in data parallel applications. Because the performance of GPU is related to the magnitude of the load received, effective load allocation methods are very important...

In this paper, the quaternion method is used to get the accurate aircraft attitude. It is introduced coordinate system and attitude angle establishment, attitude angle acquisition and data fusion algorithm in detail. Experiments show that the algorithm effectively suppresses the gyroscope deviation and...

Path planning in complex environment is the main foundation of flights automation navigation. Therefore, this paper aims to propose an algorithm combined ant colony optimal algorithm with potential field heuristic information. The main implement method of this algorithm is to use the information between...

One primary goal of structural reliability analysis aims at computing the probability of failure of a component or system with respect to some prescribed performance functions. In modern engineering, most performance functions usually resort to running an expensive-to-evaluate computational model, which...
