This paper depicts the implementation of a colorful RGB-LED light source with an 8-bit microcontroller. The microcontroller regulates LED light output with pulse-width modulation current and changes the light color with the current ratios of red, green and blue LEDs. While the LED light output varies with temperature, the microcontroller stabilizes the light output of LED with feed-forward compensation and reduces the color deviation in chromaticity diagram. The color deviation is measured with a miniature spectrometer and the calibration of white balance is executed based on the chromaticity coordinates of the used red, green and blue LEDs. Some color points inside the chromaticity diagram and along the blackbody locus are tested to verify the performance of the RGB LED light source. Test results show that an 8-bit microcontroller may effectively regulate the light colors and brightness of a RGB combinational light source. The implemented RGB LED light source can be a good light fixture for mood lighting in somewhere, such as, hotels, restaurants, hospitals, advertisement walls and others.

In order to solve the uncertainty and time-varying problems of the complex process during variable operations, a novel multiple-model predictive control system based on fuzzy adaptive weighted is investigated in this paper. Firstly, based on the model-set selecting method for multiple model adaptive control, this system preserves the performance of multiple-model approximating nonlinear property of controlled plant at close quarters, therefore the control system is robust. Secondly, fuzzy adaptive weighted control algorithm is proposed to overcome the output disturbance that caused by model switching. The weighted values are obtained by fuzzy decision-making. In this way the corresponding controller can be switched smoothly when the model is selected through switching. Thirdly, because the output predictive value of practical controlled plant is calculated by weighted average of respective sub-models output probabilities, it can rapidly image the variation of plant characteristic. Meanwhile, the output value of controller is optimized by dynamic matrix control algorithm, so the system has better dynamic performance. Furthermore, because of the convenient design and good real-time performance, this algorithm is of great significance and practical engineering value. This algorithm is applied to the main-steam temperature of a supercritical 600MW Once-through boiler; simulation experiments demonstrate the feasibility and good performance of the proposed approach compared to the former approaches.

The water consumed by power plants is about half of the total annual industrial water consumption in China. Considering some characteristics of wastewater in power plants, the paper presented a new process to treat the wastewater. In the process, wastewater was made centralized treatment utilizing activated sludge firstly, then water purifying agent was put into the wastewater and they were coagulation sedimentation. The wastewater was treated by aeration and disinfection at last. In order to increase the efficiency, the ash conveying water was used as the cogulating aid in the process. The experimental results showed that the presented process was effective. The quality of the wastewater after treated was stabile and the ash conveying water was beneficial to the flocculation promotion. The effluent was well used for the circulating cooling water system. It can be concluded that the wastewater of power plants can be the supplementary water of the circulating cooling water system after appropriate treatment. The engineering practice indicated that the process can reveal the social, economical and environmental benefits and be helpful to the realization of the zero discharge of the power plants.

We speak languages sometimes fast and sometimes slowly. We sometimes even stop speaking suddenly, and change the topic and start speaking about another subject. And also, we sometimes speak to a person whom we have met for the first time. Even in these situations, we can happily understand one another what we are talking about even though the speech signals wave forms are independent one another. But if we apply some of today's speech analysis methods in these situations mentioned above, we may totally get different answers or even cannot apply those methods. And what is worse, application of those methods are quite difficult and it is not understandable what will be the causes in a practice situation. So on this paper, I have tried to study a simple method which can apply to in the difficult situations mentioned above by using Vector Analysis Method and Back Propagation Neural Networks Method, which mainly focuses on “Word feedback and Sentence feedback”.

The omni-directional cameras providing 360 degrees field of view (FOV) are widely used in video surveillance and robot vision applications. However, the omni-directional cameras have an obvious drawback; that is, only low-resolution images captured. Therefore, the objects are not able to be correctly identified if they are far from the omni-directional cameras. To overcome this problem, we propose a high-definition human face tracking system using the fusion of omni-directional and pan-tilt-zoom (PTZ) cameras. Our system first detects and tracks human faces in the panoramic images received from an omni-directional camera, and then controls the PTZ camera to fixate at a target face for capturing a high-resolution image. At the beginning, the human face detection procedure obtains moving human faces by means of temporal differencing together with skin and hair color filtering. The detected human faces are subsequently fed to the face tracking procedure which employs a particle filter for iteratively tracking human faces. Once a target human face is selected, the PTZ camera is directed to stare at the target and zoom in it speedily. Then the face tracking procedure turns to use the images received from the PTZ camera for continuously tracking the target face until it is outside the FOV of the camera.

Random Projection (RP) has been proven to be a powerful technique for Dimension Reduction (DR). In this paper, it is applied to hyperspectral images as a DR preprocess step for Endmember Extraction (EE). Theoretical analysis demonstrates that RP can preserve geometric simplex fitting by hyperspectral data perfectly. Therefore, endmembers, which play an extremely important role for Spectral Mixture Analysis (SMA) of hyperspectral images, can be extracted from the projected data in a subspace by RP and the computational complexity of EE can be greatly reduced. Experimental results demonstrate that RP is computational efficient and data-independent DR technique for EE.

In this paper, the principle of Static Var Compensator (SVC) is analyzed in detail, and a kind of SVC system which consists of Thyristor Controlled Reactors (TCR) and Fixed Capacitor (FC) is designed. Bridge rectifier and L-R circuit is used to simulate the symmetrical three-phase load. Based on instantaneous reactive power theory, the SVC system signals are detected rapidly and precisely. In order to maintain the stability of the client node voltage and satisfy the requirements of system power factor, the voltage and admittance double loop control strategy is adopted, and the well-behaved steady-state effects is obtained. The break of node voltage caused by load disturbance or any other factors is restrained, and system power factor is well improved too. Finally, the SVC model is established under the environment of MATLAB simulation.The simulation results show that the proposed system can stabillize the fluctuation of power grid voltage and raise power factor, and the merits of fast response speed and high precision are verified.
