In this paper, we propose adopting the algorithm of linear prediction coding (LPC) to proceeds the temporal feature streams in speech recognition for noise robustness. Using LPC, an FIR filter can be obtained and applied to the time series of Mel-frequency cepstral coefficients (MFCC), and in general the fast-varying component in the modulation spectrum of MFCC can be alleviated accordingly. We have found that the smoothing of MFCC modulation spectrum helps to reduce the noise effect and enhance noise robustness of MFCC. Experiments conducted on the Aurora-2 connected digit database shows that the proposed LPC-wise method improves the recognition accuracy of MVN- and HEQ-preprocessed MFCC under a wide range of noise-corrupted situations.

By fusing a sequence of exposure images, we could generate a high dynamic range (HDR) image and enhance the image details. However, to display the HDR image on a low dynamic range (LDR) device, HDR compression is necessary. In the paper, a new method for HDR Compression based on matting Laplacian is proposed. The major assumption behind is that the tone-mapped LDR image must preserve the HDR local structure so that the image details could be well represented. Precisely, we treat the HDR image as a guidance image and embed the object structure of the HDR image into a matting Laplacian matrix. Further, we formulate HDR compression as an optimization problem. Through incorporating the matting Laplacian matrix into the objective function, the optimal LDR image is forced to have the similar local structures like the HDR image. Our experiments show the extracted LDR image could enhance the image details well without introducing severe edge effects or color artifacts.

This study optimizes the lighting of 38 LED chips connected in series with 14 switches to bypass parts of them according to the alternating voltage level across the LED string. Furthermore, the illumination produced by the light will not become unstable while the light is used as binary signals at the same time, to transmit data by controlling another switch.

In the globalization society, everyday life becomes easier and more convenient due to rapid development and utilization of information technologies. People are able to achieve in high-level goals comparing with the past. As a result, some of them who feel difficult to catch up the trend however lack of important morality, and eventually fail in achievement. As a leader of society, engineers who got degrees for mainly contributing in innovative invention should spend their lives in the right ways that people expected such as professor, developer, researcher, manager, engineer, and so on with the need of morality. Actually, this is a good timing for new-face engineers to carefully design their morality-based working lives in order to enhance their career path, and finally reach the success level goals. This talk starts from raising some world-level persons as good and bad samples, and analyze their results. Obviously, to become well known person with excellent career path, we need to seriously consider morality even more than achievement. Some samples typically showing achievement with morality are introduced and discussed as guidelines for the audiences. The talk concludes by a new type of leading engineer matched with the current IT society.

With information technology and the Internet developing fast, people gradually walk out of the time of information deficient and enter the era of information overload. Whether information consumers or information producers are faced with big challenge: how to obtain or sell the information. Recommendation system is a key to this problem. Traditional recommendation system focuses on connecting user interest and items, and recommends items which match user interest. However, all these algorithms ignore the context which users are in. In terms of this problem, this paper presents a novel collaborative filtering recommendation algorithm based on user location context. Firstly, this algorithm defines user location attenuation function to calculate the relations between user locations, then combines this function with traditional Pearson similarity method to get similarity between users, finally, uses the traditional collaborative filtering recommendation algorithm to realize preference prediction and recommendation. Experiments show that this algorithm which has location information taken into account can improve recommendation quality for traditional collaborative filtering recommendation algorithms.

In the present work, the effect of different parameters such as the frequency of irradiation, gas species in a bubble and its cavitation intensity (the key factor affecting the advanced oxidative process) have been studied with numerical solutions. Simulations of cavitation bubble dynamics have been made for harmonic and ultra-harmonic coupling of two ultrasound waves within the frequency range of 20kHz-200kHz with the interval of 20kHz. The results show that the cavitation intensity reduces gradually with the increase of frequency, the peak temperature reached in a cavitation bubble at transient collapse is influenced by the gas species, and in a dual-frequency ultrasonic field, the cavitational activity reaches to its maximum when the two frequency have the same value of 20kHz.

Nowadays, there are numerous multicore processors for parallel computing. The potential for parallelism is inherently provided by the dataflow execution model, which is a natural fit for exploiting the parallelism inherent in programs, especially digital signal processing applications. In our laboratory, we have developed a ring interconnected multicore dataflow DSP called LSC-Based DSP. In this work we supplement a subtraction operation to LSC-Based DSP with the function of duplicating operand data in order to provide a higher degree of programmability. We implement the new our DSP on an FPGA development board, and verify the functionality of the subtraction instruction by executing several test programs on our new DSP.

This paper presents an approach about head movement compensation for head mounted eye tracker. Eye tracker is a device for measuring eye movements and estimating POG (Point of gaze). When using eye tracker, head movement will cause the error of POG estimated, so the head movement compensation is one of important topics of eye tracker. In this paper, we use scene camera to detect circular patterns pasted on monitor and estimate monitor's depth and 3D position. When calibrating, get the information of mapping function and calibration plane, when using eye tracker, estimate visual axis by them and calculate POG, the experiment result shows this approach can reduce the error caused by head movement effectively.

In recent years, ultra-wide bandwidth (UWB) technology has been concerned because of its high signal bandwidth and high resolution. Based on a variety of measurement signal data in the near ground LOS scenario, with the signal frequency ranging from 3 GHz to 8 GHz, this paper studies the near-ground TOA ranging error variation characteristics with the bandwidth and transmission distance. Also a statistical near-ground path-loss model of ultra-wide bandwidth channel is built, with diverse antenna height, bandwidth and transmission distance. The simulation results verify the correctness of path-loss channel model.

The scattering effect of laser light irradiation on a matter surface creates motion-sensitive “speckle patterns”. The resulted Laser Speckle Imaging (LSI) has attracted a lot of attention in medical applications such as wound healing, rodent cerebral blood flow, and peripheral circulation examination due to its capability in revealing regional microcirculation conditions of tissue capillaries. However, the high price of a FDA-approved LSI system is the obstacle for being wildly used by the public. In this work we implemented two different preliminary LSI systems for comparisons. One is in scientific grade, and the other consists of low-cost consumer graded components. We examine their performance by imaging a simulated ischemic skin condition.
