Fluorescent lamps are the most popular artificial light source for plantlet cultivation. However, the spectrum of fluorescent lamps is greatly different from solar spectrum. This paper combined fluorescent lamps with blue LEDs and red LEDs, in order to carry out the experiments on Anoectochilus Formosanus Hayata. We observed and recorded the data of Anoectochilus Formosanus Hayata's living in order...
The enormous popularity of Web 2.0 social network services has led to much research on social network analysis (SNA). These studies focus on analyzing the complex interactive activities between users in the world of virtual networks. SNA has shown great potential in automatic document classification, especially in identifying citation networks of research papers and the references among them. This...
The applied electric field (EF) has shown to have great influence on epileptiform firing. Epilepsy is a dynamical disease charactered by hypersynchronous firing. Taking the electrical characteristic of extracellular medium i.e. ephaptic transmission into consideration, we build a PR model in the presence of the applied electric field. V̄DSout is the DC part of the voltage between soma and dendrite...
In this paper, a test chip is introduced to study the susceptibility of low dropout voltage regulator (LDO) by direct RF power injection (DPI) method. The structure and failure mechanism of LDO module is analyzed. Both of hardware and software DPI set-up are given to characterize the test flow. A novel test method of on-chip sensor sampling is described by the functional frame and sampling arithmetic...
Epilepsy is commonly considered to be the result of excessive firing of neurons. This paper investigates firing patterns of single-neuron in the hippocampus CA3 area based on the Pinsky-Rinzel (PR) model and uses closed-loop control with slow variable as the feedback parameter to suppress neuronal firing. Unscented Kalman Filter (UKF) is adopted to estimate the slow variables which contain important...
Designing a collaborative reading annotation tool with functionalities for annotating a digital English article can accumulate and share the knowledge of readers who participate in reading learning processes in a web-based learning environment. The annotated content helps new readers understand articles and helps readers who have read an article obtain a deeper and broader understanding than when...
With the gradual adoption of multimedia technologies in curriculum designs, the need has increased for in-depth studies exploring how different presentation techniques for multimedia materials affect learner emotions and learner performance. Therefore, this study employed the emWave system, which is a stress detector for emotional states developed by the Institute of HeartMath for measuring changes...
Manifold learning works well in discovering the intrinsic structures embedded in the high-dimensional coordinates and most of the methods lie on the distance metric. This article proposes an unsupervised learning algorithm called cam-weighted distance local tangent space alignment (Cam-WLTSA) which performs well with artificial sample data sets. The cam-weighted distance, first using in the nearest...
The carrier frequency estimation algorithm based on high-order cyclic cumulants does not need a training sequence. Due to the fact that the high-order cycle can suppress the stationary and non-stationary Gaussian noise, the algorithm is tolerant to the noise mentioned above. The computation of the algorithm is deduced in this paper. It shows that if large searching range of carrier frequency and high...
in this paper, we propose a new framework in pedestrian detection by combining the HOG and uniform LBP feature on blocks. Contrast experiment result shows that detector using combined features is more powerful than one single feature. To further improve the detection performance, we make a contrast experiment that the HOG-LBP features are calculated at variable-size blocks to find the most efficient...
In this paper, we present an improved method for face recognition named statistical Local Line Binary Pattern (SLLBP), which is based on Local Binary Pattern (LBP). The basic idea of the algorithm is to first obtain the local binary code along with horizontal and vertical direction separately and the gray-level difference between neighbor pixels, which is also important to describe a face feature...
Physically-based modeling is used in virtual assembly system to improve the feeling of immersion and make the evaluation results convinced. The handling of unilateral constraints is the capstone of modeling physical behaviors. To take advantage of both impulse-based method and analytical method, hybrid scheme for adaptive simulation is presented, where the constraint states can be transited automatically...
The dynamic model of the flywheel suspended by the active and passive hybrid magnetic bearings (HMBs) is nonlinear. The magnetic flux superposition and couple cause the dynamic model couple in different degrees of freedom (DOFs). In this paper the nonlinear dynamic model of the flywheel suspended by the HMBs in the radial translation DOFs has been obtained using the magnetic flux circuit calculation...
Selective sampling has been widely used in relevance feedback of image retrieval to alleviate the burden of labeling by selecting the most informative instances for user to label. Traditional sample selection scheme often selects a batch of instances each time and label them simultaneously, which ignores the correlation among instances and results in redundant labeling. In this paper, we propose an...
Indirect-drive electric vehicle system will improve the overall reliability and efficiency due to elimination of reduction gear and the differential gear. The paper discusses the design of direct-drive axial flux permanent magnet in-wheel machine for electric vehicle in order to achieve a wide speed range operation and low cogging torque. Fractional-slot winding and wedges made from soft magnetic...
This paper investigates various Ethernet LAN architectures for substation automation system applications with protection, control, monitoring data flows and their performance requirement.

The suitability of these architectures and the redundancy technologies for mission-critical,...
Because of the particularity of its techniques, the remanufacturing parts and ordinary parts are very different from their machining and program method. Due to the CNC software of reconfigurable machine tools is expandable, the parametric CNC programming method is researched. Parametric CNC programming modules is sorted based on typical parts and machining techniques, which is used on CNC system of...
Salient region of an image usually contains the crucial information for image analysis and understanding. Most conventional approaches learn the saliency by utilizing the low-level features, which ignore the participation of human. In this paper, we propose an effective and robust approach to detect the salient region of an image by combining the bottom-up and top-down cues. The proposed method not...
Automatic face identification of characters in movies has drawn significant research interests and led to various applications. It is a challenging problem due to the huge variation in the appearance of each character. Although existing methods demonstrate promising results in clean environment, the performances are limited in complex movie scenes due to the noises generated during the face tracking...
In this paper, we propose an automatic approach to simultaneously name faces and discover scenes in TV shows. We follow the multi-modal idea of utilizing script to assist video content understanding, but without using timestamp (provided by script-subtitles alignment) as the connection. Instead, the temporal relation between faces in the video and names in the script is investigated in our approach,...
