The measurement accuracy of the articulated coordinate measuring machine (AACMM) is different in different sub measurement regions. In order to improve accuracy, The method for dividing and merging of sub measurement region based on Density-Based Spatial Clustering of Applications with Noise (DBSCAN)...

Precision of ball screw had a great impact on the positioning accuracy of NC positioning platform. The lead error and backlash of ball screw, which could be accurately measured by laser interferometer, were two key factors affecting the positioning accuracy of NC positioning platform. By setting the...

Based on information sharing idea, BIM (Building Information Modeling) technology had been widely used in construction industry. Employment Guarantee for Migrant Workers is hot topic in Chinese construction industry. There were few articles focus on using BIM to solve the Employment Guarantee problem....

In recent years, excess production capacity has been plagued by China's economic development, especially under the background of the new normal, excess capacity in the short term and long term will cause certain negative influence to our country economy, destroy the healthy development of the industrial...

With the development and application of Internet technology, the logistics industry has entered an unprecedented period of development. In order to achieve environmental, economic and social development, circular economy has been identified as an important part of the national development strategy and...

Because of the changes in professionalism and national policies, the postgraduate entrance examination for medical students has become an essential choice. Under the high rate of students taking part in the examination, due to the lack of information, a large number of medical students have to take the...

Mobile ubiquitous technology and IPv6 technology makes it possible to perform the remote control and information transfer by using the mobile terminal, and it promotes the development of the Internet of things. Therefore, more and more intelligent terminal devices need mobility support, such as intelligent...

This paper analyzes the reason why the civil aviation enterprises attach great importance to service quality, but the passengers are not much satisfied. And then it puts forward a scientific solution based on humanism and interconnected intelligent equipment. The paper also defines the concept of a smart...

A high-performance ultra-wideband (UWB) monocycle pulse generator is described in this paper. The pulse generator circuit is mainly composed of avalanche transistor, step recovery diode (SRD), Schottky diode (SD) and microstrip lines. The proposed circuit solution utilizes the avalanche effect of avalanche...

It described a control system of 100kV high voltage power supply. It used PC control and monitor the power modules via fiber optic. By testing, proved the control system is a good isolation and provides stability control system. By this way, we can remote control the power modules.

This paper describes a new approach for implementation of an efficient real-time system proper for using in active video conferencing sessions. A camera tracks presenter’s head and its movements and orientations in an unconstrained environment automatically by its pan and tilt actions. Head or face is...
