Analysis and practical implementation of the regular symmetric sampled three-phase PWM inverter waveform has been presented in this paper. It is digitally implemented on a Xilinx field programmable gate array FPGA, and the essential considerations involved in the feasibility of using a Xilinx XC4008E software-based to generate PWM has been discussed. All the necessary Xilinx hardware/software t...

凝固波形解析（clot waveform analysis: CWA）は自動凝固分析装置を用いた凝固機能評価法として発展している．CWAはプロトロンビン時間（prothrombin time: PT）や活性化部分トロンボプラスチン時間（activated partial thromboplastin APTT）の “凝固時間” のみならず，装置内で解析した結果を画面に表示することができ，汎用性が高いため，臨床検査室で凝固異常症の迅速な鑑別ができる．近年，CWAが出血性疾患だけでなく，血栓傾向を示す疾患に有用だと報告された．今後は，波形による鑑別の精度向上が課題である．一方，APTTによる凝固反応の後，フィブリン溶解過程を評価できる凝固線溶波形解析（clot fibrinolysis CFWA）が登場した．CFWAは，間接的に凝固のみならず線溶能や線溶抑制効果を反映する画期的な方法で，...

The Functional Electrical Stimulator design using monophasic spike-exponential waveform was proposed and described in this study. The monophasic square waveform has benefit in generating an action potential, but it could cause side effects such as toxic caused by the electrode polarization. The square waveform signal which the frequency and pulse width could be modulated was manipulated to be t...

The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...

PURPOSE To investigate the proper usage of wavelet analysis in infantile nystagmus syndrome (INS) and determine its limitations and abilities. METHODS Data were analyzed from accurate eye-movement recordings of INS patients. Wavelet analysis was performed to examine the foveation characteristics, morphologic characteristics and time variation in different INS waveforms. Also compared were the...

Laser range data analysis is of high interest in photogrammetry. Range estimation for complex surface structures can be inaccurate. To overcome this drawback a method using a laser scanner capable of full-waveform analysis is proposed. For analysis the transmitted waveform of the emitted pulse is used to estimate the received waveform of the backscattered pulse for a known surface. We simulated...

We present a systematic study of signal propagation conditions (PCs) starting from a general waveform model. We develop a number of specific waveform models based on how closely they match actual signal behavior, and show that they form a well-defined hierarchy. For each model, we derive PCs based on fundamental cause-and-effect behavior. We then construct a lattice of all known PCs that reveal...

Recent advances in Light Detection And Ranging (LiDAR) enable digital acquisition and storage of the entire waveform of backscattered laser pulse energy. Pre-requisites for extracting target radiometric and geometric properties via waveform analysis include defining a model for accurately determining peaks in the return energy waveform and a method for transforming waveform peak amplitudes to a...
