At present,3-D model can be build through point clouds data which is quickly get by laser scanning technology. Most of the researches on registration problems are focused on feature matching method. This paper discusses a method with global optimization algorithm. In order to solve the problem efficiently,...

Traditional methods, when applied to change detection in remote sensing images of damage areas with complex terrain, often result in inaccuracy. And it is difficult to select an appropriate threshold, which however can be solved by support vector machines (SVM) method. Conventionally spectral information...

Overheating and radiation from power equipment is a crucial factor for a variety of failures and anomalies. This paper presents a substation inspection system based on computer and embedded system for temperature measurement and smart fault location for power equipment, to improve the reliability and...

In this paper, we investigate a class of Linard type p-Laplacian equation on times scales by generalized Mawhin’s continuation theorems, under suitable conditions, we ensure that at least one periodic solution to this kind of p-Laplacian equation on time scales exist.

In this paper, some oscillation theorems of differential equation of the even order are established here is even, The theorems extend and supplement some results in the literature. An example is investigated to illustrate our results.

This method for fuzzy comprehensive evaluation by fuzzy mathematics evaluate gob spontaneous combustion risks, builds a risk index system of gob spontaneous combustion in combing the characteristics of combustion in the goaf and established a fuzzy comprehensive evaluation model of natural fire in goaf,...

An optimum background correction method based on the Gerchberg-Saxton (GS) algorithm is proposed to improve the beam shaping effect of a computer-generated hologram. The zero-value pixels of a black-white image which is used as the target optical field in a beam shaping process is replaced with an optimum...

The three stages complete information multi-players dynamic game between visitors, local governments and parks managers is proposed in this paper to solve the significant problem about the investment on the visitor education. The game reveals that the government should set up induction fund to lead the...

Compared to desktop geographic information systems (GIS), current WebGIS are still rather poor in terms of interface and functionality. Much of this discrepancy is due to the limitations of current web standard (HTML4). HTML5 is being developed as the new web standard to replace HTML4. It provides plugin-free...

Purpose: Research and theoretical substantiation of the hearing Weber law for sounds arbitrary frequencies and intensities. Objects: Results of classic psychophysical experiments of Weber, hearing Fechner model (equation) as a special case of the Weber law. Methods: Audiometric for determining hearing...

Sewerage, one of major underground pipelines, is an important infrastructure for a modern city. In order to keep sewerage in a good structure and performance condition, planned routine inspection and rehabilitation are necessary. At present, image processing and artificial intelligence techniques have...

A structured light binocular stereo vision measurement method was proposed which can be applied to deal with the odometry problem of moving objects in low-light environments such as underwater and enclosed spaces. On the basis of binocular stereo vision system, we use structured light to irradiate the...

This study aims to compare the structure of medical reports of same type medical examination but composed by different physicians. An analysis and compare method was proposed based on formal concept to produce different concept structure for medical reports. Important concepts of medical reports can...

With the extending of the scope of information sharing and data exchange, ontology, as the formal specification of share concepts, is more and more useful. FCA had remedied deficiency of existing method of ontology building. In this paper, the existing methods of domain ontology building are presented,...

What is a security network In this paper, a security network is considered as a diagram of security systems deployed in different places in a guard zone. For a security network, its vulnerability is an important metric to judge whether its protection effectiveness is good or not. How to evaluate the...

Cloud computing concept has overhauled the entire structure representation, required for the implementation of IT Infrastructure. This cloud computing approach is gradually eliminating the existing client server system and grid computing. The capabilities associated with the innovation of cloud computing...

In this study, an anti-counterfeiting algorithm is proposed to prevent the traceability code from being forged. The traceability code is enciphered using the encryption matrix generated by Chebyshev chaotic neural networks, which is then hidden as an invisible watermark in the package label. If the watermark...

The machine vision measurement system was established to measure 2D sizes of parts. The 5 Megapixels CCD sensors, bi-telecentric lenses, telecentric back illumination and image acquisition modes were chosen to establish hardware part, according to the requirement of views and precision. The software...

Big data is the source of creative thinking, broad cognition and creation of new values. The technology revolution makes us living in the age surrounded by the explosion of geometric level data, the era of big data. Promoting the reform of college English, college English teaching has an urge to set...

When the enterprise received the service request from the customer, firstly it will collect the maintenance services at the same time for generating the task list, and then match the right person to perform the task to meet custom needs. Therefore, it is a key issue for the enterprise how to select maintenance...
