An approximate implicitization algorithm for planar parametric rational curve is presented in this paper. Based on the optimization theory, the coeAEcient vector of the implicit form is proved to be the minimum solving vector of a real quadratic form, or a nontrivial solution of a homogeneous linear equations system. Considering the complexity of the implicit representation and the numerical computation, lower degree and geometric continuous approximate implicitization algorithms are also discussed. And the eAEciency of the proposed algorithm is illustrated by several numerical examples. |

We propose an approach for real-time blind source separation (BSS), in which the observations are linear convolutive mixtures of statistically independent acoustic sources. A recursive least square (RLS)-like strategy is devised for real-time BSS processing. A normal equation is further introduced as an expression between the separation matrix and the correlation matrix of observations. We recursively estimate the correlation matrix and explicitly, rather than stochastically, solve the normal equation to obtain the separation matrix. As an example of application, the approach has been applied to a BSS problem where the separation criterion is based on the second order statistics and the non-stationarity of signals in the frequency domain. In this way, we realize a novel BSS algorithm, called exponentially weighted recursive BSS algorithm. The simulation and experimental results showed an improved separation and a superior convergence rate of the proposed algorithm over that of the gradient algorithm. Moreover, this algorithm can converge to a much lower cost value than that of the gradient algorithm |

A mobile phone-based Internet system for health monitoring and management is proposed. This system comprises an Internet server for automatic health information processing and thousands of wearable compound devices for monitoring physiological signals. Awearable compound device (dubbed an 'i-monitor') consists of a tiny attachable pad ('i-pad') and an i-mode cellular phone ('i-phone'). Multiple physiological signals are acquired by the i-pad, which is attached to the breast surface beneath the clothes of a user. Preliminary diagnosis is performed within the i-pad. Whenever abnormality is detected, the i-pad initiates a connection with the i-phone, transmitting data to the i-phone using the Bluetooth protocol. The i-phone relays this data to an i-health server through the Docomo DoPa wireless network using the TCP/IP protocol. The i-health server performs comprehensive analysis of the received data using various data mining methods, and then returns the diagnostic outcome as well as healthcare instructions back to the user. |

Correct interpretation of electrocardiogram (ECG) is important for treatment of patients with acute myocardial infarction (AMI). A large number of posterior AMI manifests ST elevation in posterior leads V7-V9 that are beyond the standard 12-lead ECG. In this paper, we propose a method with that ECGs on posterior leads V7-V9 are derived from the standard 12-lead ECG. The posterior ECGs are calculated by a linear combination of eight measuredECG signals based on information redundancy in the 12-leadECG system. One part of a 15-lead ECG database is used to derive a transfer matrix basedonthe least squaresmethod, which represents the inherent relation among body surface ECGpotentials. The other part of the database is used to evaluation the derived posterior ECG by comparing the derived ECGs with measured ones. A quantitative evaluation is performed with an automatic ECG interpretation program.The results show the accuracy of derived posterior ECGs is suAEciently good to provide useful information in diagnosis of posterior AMI. |

In Proceedings of IEEEEMBS Asian-Pacigfic Conference on Biomedical Engineering. International Association of Biomedical Engineering, IEEECD-ROM, Oct. 2003.
An approach based on the Independent Component Analysis (ICA) was presented to reject noise and extract respiration signals and pulse signals which are contained in the pulsatile signals measured from a pillow cuff installed on the occiput of a user. Because there are only two observations for a measuring system that is a linear mixture of three sources: pulse, respiration, and noise, usual ICA cannot separate them perfectly. To solve this problem, a two-step algorithm was proposed. |

The ambulatory ECG has been an important tool for diagnosis of arrhythmias. A recent trend is to use 12-lead ambulatory ECG for diagnosis of myocardial ischemia with ST abnormalities. To overcome the gap between the diagnosis methodology of the ambulatory ECGand the standard 12-lead ECG, a compromised strategy is conducted to convert the ambulatory ECG to the standard 12-lead ECG. Through evaluations, a satisfying result is obtained that the standard 12-lead ECG can be well approached by the seated 12-lead ECG. This preliminary study may play an important role on the clinic diagnosis of the ambulatory ECG. |

In this paper we propose and investigate a recursive approach for blind source separations (BSS) or/and for independent component analyses (ICA). Based on this approach we present a deterministic (without a stochastic learning) algorithm for real-time blind source separation of convolutive mixing. When employed to acoustic signals, the algorithm shows a superior rate of convergence over its counterpart of gradient-based approach based on our simulations. By applying the algorithm in a real-time BSS system for realistic acoustic signals, we also give experiments to illustrate the effectiveness and validity of the algorithm |

In this paper we propose and investigate a recursive method for blind source separations (BSS) or/and for independent component analyses (ICA). The relation of this recursive method of BSS/ICA to the conventional gradient-based method is quite similar to the relation of the RLS method to the LMS method in adaptive filtering. Based on this method we present a novel algorithm for real-time blind source separation of convolutive mixing. When we employ the algorithm to acoustic signals, simulations show a superior rate of convergence over its counterpart of gradient-based method. By applying the algorithm in a real-time BSS system for realistic acoustic signals, we also give experiments to illustrate the effectiveness and validity of the algorithm |

In 8th International Conference on Knowledge Based Intelligent Information & Engineering Systems (KES2004), Wellington, New Zealand, page Accepted, Sep. 2004.
We present a novel algorithm for independent component analysis (ICA) based on gradient learning with simultaneous perturbation stochastic approximation (SPSA). This algorithm can work well both in batch mode and in online mode of ICA processing. It converges very fast even for non-stationary, and/or non-identically independent distributed (non-I.I.D.) signals, so that the algorithm is very suitable for most real-time applications. In this paper, theories and implementations of the algorithm are described. Results of computer simulation are also presented to demonstrate the effectiveness |

In ITC-CSCC 2004 (The 2004 International Technical Conference on Circuits/Systems, Computers and Communications), page Accepted, Apr. 2004.
paper presents a new method for speech extraction by a combined subband independent component analysis (subband ICA) and neural memory. In the method, subband ICA separates the signals obtained from microphones into the signal components of interest and the rest at each subband. The neural memory represented by probabilistic neural networks (PNNs) is then used for identifying the signal components of interestamongthe separated compo-nents and thereby solving both the permutation and scaling problems which are of fundamental to the subband ICA approach. Simulation results show that we compare the proposed approach with the full band/subband approach |

According to the Echo-Avoidance(EA)model, the precedence effect is caused by the inhibition of sound localization which depends on the estimated sound-to-echo ratios.We tested the EAmodel using stimuli of click sounds, constant pure tones, speech and noise. After compared with the results of psychological experiments concerned with the precedence effect, such as double-click sound experiments, the Hass experiments and the Franssen experiments, we could conclude that theEAmodel of the precedence effect is an eAEcientmodel and is supported by the psychological data. |

Environmental sound recognition is an important function of robotic audition. In this research, we tried to use a multi-layered perceptron type NN system for environmental sound recognition. The input data is the one dimensional combination of instantaneous spectrum at power peak and the power pattern in time domain. Since for almost environmental sounds, their spectrum changes are not remarked compared with speech or voice, the combination of power and frequency pattern will reserve the major features of environmental sounds but with drastically reduced data. Two experiments were conducted using an original database and a database created by the RWCP. The recognition rate for about 45 data types kinds of environmental sound was about 90and simple, and suitable for a on-board system of a robot which can be used for home use, e.g. a security monitoring robot or a home helper robot |
