In order to explore the more suitable conditions for using the edible vegetable oil in daily life, the peak position, peak shape, peak intensity and peak area detected by Fourier transform infrared spectroscopy (FTIR) of four different kinds of edible vegetable oils without heated and heated beyond the...

Aiming at the inadequate or excessive exposure problem existed in the imaging system in a scene where there is no specific background or foreground, this paper presents a histogram-based exposure evaluation method. With analysis of statistics features of histograms in different exposure type images,...

For studying a three-dimensional vibrating screen based on the fluid-filled pipe, a vibration testing system based on hydraulic excitation was established. The pressure wave generated from the vibration exciter will stimulate the pipe network to vibrate. The elastic plate served as the vibrating screen...

For large, permanently-installed ME (medical electrical) equipment and ME systems, the EMC (Electromagnetic compatibility) on-site test items and the attentions for each test item are introduced. By analyzing the requirements of CISPR 11 and IEC60601-1-2, the On-site test of electromagnetic radiation...

Hydrothermal Spallation Drilling (HSD) is a relatively new method suitable for drilling through hard and brittle rocks usually encountered in deep wells and more commonly in geothermal well drilling. Up to 70% of the cost of a geothermal energy project is spent on drilling since today almost all deep...

In this paper, we analyzed the muffler acoustic performance by the finite element method and Virtual.lab. We changed the simple expansion chamber muffler size and expansion ratio related, expansion cavity length, and the number of expansion chambers effectively to improve the muffler. Through muffler...

Based on the standard atmospheric polarization model, the principle of bionic polarized light orientation is studied, and the formula of solar height angle and azimuth angle is given. Then the calculation method of polarization degree and polarization azimuth angle is studied. The method of calculating...

In view of the problems existing in current underground garage, underground garage is considered in the design of Tongcheng Yuli district. The square PC plate dormer window of pyramidal of size 3 x 3 meters is set in the roadway above. After the completion of the building, the field measurement and questionnaire...

According to the workload requirements of multi-legged robots, the standing posture of hexapod bionic robot based on static analysis is proposed in this paper, which aims to reduce the energy consumption. We chose the picnic insects with low speed as the bionic prototype and build the robot model, Through...

Underactuated mechanism is a nonlinear system which dimension of input is less than one of state. There are still some problems to be explorations in underactuated mechanism control, especially in ones with multi-DOF. The model reference adaptive control is proposed to solve the control problem of a...

Estimation of body size using related dataset is one of the challenging tasks in modeling and simulation area. It has a wide range of utilization in many aspects in society including body modeling, designing clothes etc. It is necessary to extract feature data in body size measurement. Except ordinary...

Business Process Model and Notation (BPMN) is being becoming the most used standard for business process modelling. One of the important upgrades of BPMN 2.0 with respect to BPMN 1.2 is the fact that Data Objects are now handling semantic elements. Nevertheless, BPMN doesn't enable the representation...

This paper introduces the concept of genes to the design of the product, put forward and set up product genetic model, aimed at apply the principle of gene expression to implement the product intelligent design, and strengthen the autonomy of product design, reduce artificial participation and related...

This paper introduces the concept of ecological system to the design of the product, put forward the concept of product digital ecosystem and established the corresponding model, designed to draw lessons from ecological system, and apply the mechanism of self-organization and adaptive, when design demand...

The present paper summarized the results of the most commonly adopted calculation models for total solar irradiance on inclined surface. The solar irradiance on inclined surface in Beijing was taken as an example and was simulated using Liu and Jordan, Klucher, Hay, and Perez sky models and the results...

As an important branch of linear motors, linear oscillating motor with high frequency provides reciprocating motion within short-stroke, which shows high efficiency, large power density and convenient maintenance, and has an important application value in electric vehicles, aviation and medical field....

In a survey with 73.56% response rate of 662 employees in 21 work units among 9 industries, across multiple organizations, by using questionnaire with convenience sampling and stratified sampling to get sample data, the relationship among ethical leadership, ethical climate and moral efficacy were examined....

Experimental study on spontaneous combustion of grain dust was carried out in a cylindrical combustion chamber with vertical flow. Thermocouples and gas sample analyzer were used to measure the temperature and gas of spontaneous combustion respectively. The influence of ventilation volume, bulk density...
