This paper discuss the smoke sensor and the relay control in the smart home.STM32 is used as the central part of the whole system and LwIP protocol is also applied to transfer data. The system uses the MQ-2 smoke sensor detect the concentration of combustible gases in air, and uses the SRD-05VDC-SL-C...

Synthetic aperture radar is a vital tool for imaging and remote sensing regardless of the villainous weather. Polarimetric synthetic aperture radar obtains the polarization characteristic of targets through polarized wave. This paper presents a novel technique, the combination of digital beamforming...

The limestone Detection System is developed by Qt assisted by Qwt and Modbus protocol based on Linux platform. The system can detect activity of limestone and PH value in real-time. This article begins with a brief description of the background and the functional requirements of the system, given the...

As to solve the issues of insufficient training data and initial parameters sensitive in existing protocol anomaly detection based on hidden Markov model, presenting a new protocol anomaly detection method based on improved genetic algorithm and hidden Markov model. First, the local competitive selection...

Intelligent circuit breaker is one of the most significant devices in the electric system, and its stability and reliability are quite significant for the operation of the power grid. An online monitoring and fault diagnosis system based on the vibration signal of virtual instrument technology is proposed...

A gray level image segmentation algorithm is proposed based on Average Intensity Project (AIP) and shift Gaussian model for gray level images with connection between thread and area with similar gray level. The evaluation is performed on 30 gray level images, and the results show area overlap measure...

Please make the page settings of your word processor to A4 format (21 x 29,7 cm or 8 x 11 inches); with the margins:...

It is highly important to choose suitable of the foundation in underground engineering. With the engineering, the foundation is made of gravelly soil, which distributed discontinuity and had bad uniformity. Drilling method, dynamic sounding method and deep plate loading test were applied, combined with...

Dense correspondence is a key problem in binocular stereo vision. The existing solution for this problem can be divided into local method and global or semi-global method. Bilaterally weighted patches matching is a classical local method, while it is computationally expensive and its accuracy need to...

For only one node assisting the cluster head node to send information in wireless sensor network cooperative transmission, an opportunity cooperative MIMO transmission scheme is proposed based on gradient algorithm. The results of analysis and simulation show that the cooperative transmission schemes...

Previous research uses eye blink sensor technology to detect driver's fatigue, which has some limitations in the condition of wearing glasses and lighting changes. To overcome those problems, this paper proposes a way to detect fatigue for drivers through video images and grip forces on steering wheel....
