Electro hydraulic proportional pressure-flow compound valve (P-Q valve) is a new type of energy saving combination valve. The velocity and output force of the actuator can be proportionally controlled by the P-Q valve in different working state. The author puts forward a new scheme that the hydraulic...

For the current general heating control system tracks the set temperature hysteresis heating device to automatically adjust the real-time problem of poor design a fuzzy self-tuning proportional-integral-derivative (PID) controller parameters. Scoop out using PID control and fuzzy control algorithm combined...

In order to overcome the influences of model mismatch or sometimes non-linear variables and interference in generalized predictive control process, that cause a lag, being unstable and uncertain and make the predictive result not ideal, the paper presented a generalized predictive optimization control...

The development and application of network teaching system is conducive to promoting the construction of online courses, teaching methods and means. This paper designs a network teaching system framework, functions, the establishment of the network teaching system database, the realization of the network...

Falls that lead to fatal injury have become a great challenge that cannot be neglected for elderly people. In this study, a surveillance system based on SensorTag and Windows 10 IoT Core for real-time fall detection is proposed. Raw data including three-dimensional accelerometer, gyroscope, and magnetometer...

Objective To analyze the expression of microRNA in Chinese and Italy women by a series of data mining methods to rendering microRNA network. Methods Using T test, Pearson correlation method to deal with the data, Using Cytoscape3.2.1 to draw the interaction network, and do the analysis. Results After...

Objective We use database language for data mining in order to find differentially expressed miRNAs. Methods We first construct the E-R model, then the data were converted into the appropriate format, and the converted data were imported into the database accurately. In the end, we extracted the data...

Tracking-Learning-Detection(TLD) algorithm has the advantages of high speed, high accuracy of tracking rate and self-detection mechanism. However the sensitivity to illumination variation and background clutter leads to drift even miss for TLD algorithm under the complex environment. An improved TLD...

The composite cigarette sorting system efficiency depends on a combined configuration of high flow sorting units and general sorting ones. This article innovatively proposes the polling theory of unit materials based on the actual demand for order picking under the herein scale. Put forward Exhaustive...

In this paper, two inverse vibration problems of constructing a grounding spring-mass system from its two eigenpairs and part of spring stiffness are considered. The vibration system is constrained to satisfy a relation that the total mass of system is a constant, and the problems are transferred into...

Resistive sensor is widely used in every aspect of production and life, and it has many good qualities, like wide resistance range, nonlinear resistance change and so on. Resistance sensor measurement system is an important step of design and improvement of the property of resistive sensor. A reformed...

According to the need of modern competition and the operation and management of the supply chain, this paper analyzes the frame and system structure of a visualized supply chain, further reveals the technologies on supply chain acquisition, integration of heterogeneous data, data analysis and processing...

With the rapidly developing of electrified railways; the power quality problems caused by traction power supply system have been increasing taken into account by railway and electricity department. In order to evaluate power quality, the models based on PSCAD/EMTDC of typical traction power supply system...

In this thesis, we implement a fast human face detection system based on the the latest real-time feature detection algorithms presented by Paul Viola [1]. Based on the implementation of the algorithms developed by Paul, we developed a quick image scanning algorithm and an algorithm for simple classifier...
