  • This paper presents a new method for finding the Block Pulse series coefficients, deriving the Block Pulse integration operational matrices and generalizing the integration operational matrices which are necessary for the control fields using the Block Pulse functions. In order to apply the Block Pulse function technique to the problems of state estimation or parameter identification more efficiently. it is necessary to find the more exact value of the Block Pulse series coefficients and integral operational matrices.

  • In this paper, Ire present the result of feature points recognition and classification of radial pulse by the shape of pulse wave. The recognition algorithm use the method which runs in parallel with both the data of ECG and differential pulse simultaneously to recognize the feature points. Also we specified 3-time elements of pulse wave as main parameters for diagnosis and measured them by execution of algorithm. then we classify the shape of radial pulse by existence and position of feature points.

  • Since ${\ll}$Hwangjenaegyeong(黃帝內經)${\gg}$ and ${\ll}$Nangyeong(難經)${\gg}$, there has been various methods in pulse diagnosis. The Chon-gu(寸口)/Inyeong(人迎) Pulse Comparison Diagnosis which is dealt with in many chapters of the ${\ll}$Hwangjenaegyeong${\gg}$, has not been as widely applied as the Chon-gu Pulse Diagnosis due to several limitations. In this paper, we will review these limitations and suggest an alternative method. In the Chon-gu/Inyeong Pulse Comparison Diagnosis, we compare the Chon-gu Pulse and the Inyeong Pulse to see which is larger than the other by times, and diagnose illness of the 12 Meridian Pulse. It is fairly clear which is larger than the other, but to determine by how much accurately is quite difficult to say. However if we combine the Five Viscera Pulse in application, it becomes far more easier to determine which viscera and bowel is ill. First, study the pulse of the Chon-gu and In-yeong, then determine the Viscera Pulse. Next, determine the larger pulse between the Chon-gu and In-yeong pulse.

  • Objectives : This paper is to find the meaning of Tan pulse in Qikooujiudamai Diagnosis, Methods : In terms of Qikooujiudamai, the position to diagnose the Intermittent Pulse is Kwan(關) position and the pulse is Tan(彈) pulse. To find the meaning of Tan pulse, the symptoms of Intermittent pulse were analyzed. Then the symptoms were analyzed in terms of both Qikooujiudamai Diagnosis and 28-pulse diagnosis to find the correlation. Results & Conclusions : The Tan pulse at Kwan position is related to Hyen(弦), Kin(緊), Hwal(滑), Dan(短) pulse in 28-pulse diagnosis. The symptom of disease of Intermittent pulse's diagnosis is mostly concluded to those 4 pulses. Qikooujiudamai is the diagnosis for acupucture treatment, but with 28-pulse diagnosis, it can be developed to usage of medicine.

  • The ultrasonic pulse velocity test has a strong potential to be developed into a very useful and relatively inexpensive in-place test for assuring the quality of concrete placed in structure. The main problem in realizing this potential is that the relationship between compressive strength ad ultrasonic pulse velocity is uncertain and concrete is an inherently variable material. The objective of this study is to improve the reliability of in-place concrete strength predictions by ultrasonic pulse velocity method. Experimental cement content, s/a rate, and curing condition of concrete. Accuracy of the prediction expressed in empirical formula are examined by multiple regression analysis and linear regression analysis and practical equation for estimation the concrete strength are proposed. Multiple regression model uses water-cement ratio cement content s/a rate, and pulse velocity as dependent variables and the compressive strength as an independent variable. Also linear regression model is used to only pulse velocity as dependent variables. Comparing the results of the analysis the proposed equation expressed highest reliability than other previous proposed equations.

  • This study was designed to investigate the effects of stimulation intensity and inter-electrode distance on the parameters of the measured sensory nerve signal. 30 healthy subjects participated in this study. Sensory nerve signals were elicited by four different pulse amplitudes, i.e., 3, 6, 9, 12 mA, with the pulse width fixed at $500{\mu}s$. The sensory nerve signals elicited by the four different pulse amplitudes were measured by four different inter-electrode distances (20, 30, 40, and 50 mm). We extracted four parameters (pulse amplitude, pulse width, pulse area, and latency time from stimulation) from the sensory nerve signals. The measured pulse amplitude and pulse width were increased when the measuring inter-electrode distance was increased while the stimulating pulse amplitude was fixed. The measured pulse amplitude was saturated with the stimulating pulse amplitudes of over 6 mA while measuring inter-electrode distance. Under the same condition, measured pulse width was increased, and sensory nerve signal was initiated early. Sensory nerve signals, specially those of pulse amplitude, were distorted by a differential amplification method that commonly measures the human body signal. The experimental results indicate that the differential amplification method is required to be replaced when measuring nerve signals. Our observations suggested that the hyperpolarization of the action potential of the sensory nerve signal for preventing distortion could be used to clarify the correlation between the parameters of the sensory nerve signals and quantification of sensations.

  • This study aims to develop a system for diagnosing pulse and disease conditions based on oriental medical classics to collect objective quantitative information in the traditional pulse examination environment that uses fingers. For this purpose, the study suggested a thimble-type sensor unit as the most appropriate pulse analyzer and proposed a traditional method to measure the pulse pressure wave on the spots of cheok, gwan and chon by installing the pulse analyzer on the forefinger, middle finger and medical finger. Then, it was interpretively found that this pulse analyzer enables us to objectively recognize 28 pulses defined in Oriental medical classics including the yukjo pulse, described as the buchimjisak-heosil pulse, and the hong, yoo, hyeok and san pulses. Finally, the study proposed a method to extract key parameters essential to pulse condition diagnosis from the pulse pressure wave measured by this pulse analyzer.

  • In this paper, we present a novel pulse train identification method for two step stagger pulse train. Generally radar uses a fixed pulse train, and it is easy for electronic warfare system to measure the pulse repeat interval(PRI) and identify the radar. But it is very difficult to measure the PRI of stagger pulse radar because the pulse interval is periodically changed. We suggest a novel method to measure the PRI and identify the radars using the second deviation of pulse train. This method is faster comparing with Histogram method. We have a good PRI measurement results for 2 step stagger signals.
