This paper initiates a new investigation of optimum transmission waveforms in the presence of per-path pulse wave shape distortion – a physical mechanism unique to impulsive signals. First, the transient electromagnetic analysis is carried out to derive, for the first time, closed-form expressions for the impulse responses of several canonical channels that are suitable for communication engine...

In the last seven years, optoelectronic tweezers using optically-induced dielectrophoretic (ODEP) force have been explored experimentally with much success in manipulating micro/nano objects. However, not much has been done in terms of in-depth understanding of the ODEP-based manipulation process or optimizing the input physical parameters to maximize ODEP force. We present our work on analyzin...

We consider re ection of a pulse in a random medium with a strong re ector. We show that the wavefront of the re ected wave observed in the frame moving with the random propagation speed stabilizes to the deterministic waveform. The problem is studied using invariant imbedding. The results of numerical experiments illustrating the theory are presented.

The reliability of three new template matching techniques for detecting ventricular tachycardia (VT) using intracardiac waveform morphology was assessed using nonparametric tolerance intervals. These new techniques, the bin area method (BAM) , the normalized area of difference (NAD), and the derivative area method (DAM), were compared with correlation waveform analysis (CWA), an established met...

UNLABELLED Clot waveform analysis extends the interpretation of aPTT measurement curves. The curve is mathematically processed to obtain information about fibrin formation kinetics including semiquantitative determination of thrombin, prothrombinase and tenase activity. PATIENTS, METHOD In this study the feasibility of clot waveform analysis for monitoring of haemophilia A was investigated us...

Threshold and timing parameters are two fundamental factors that control arrival times and waveform signatures collected in an acoustic emission test. While this approach works successfully in many applications, recording the complete, continuous waveforms emitted from an AE test independently of threshold value is more appropriate for some specific applications. Applications such as those with...

The history of blood pressure (BP) waveform analysis is almost as undulatory as the waveform itself. The development of the sphygmograph in the mid-19th century led to a relatively brief, albeit intense, interest in the interpretation of the BP waveform. This was perhaps more an art than a science, and interest in the sphygmograph and the waveform declined after the introduction of the cuff-bas...

Due to the nonlinear nature of the Bang-Bang phase-locked loops (BBPLLs), its transient analysis is very difficult. In this paper, new equations are proposed for expression of transient behavior of the second order BBPLLs to phase step input. This approach gives new insights into the transient behavior of BBPLLs. Approximating transient response to reasonable specific waveform the loop tran...

This paper describes a new technique for automatically parameterising the inverse filtered speech waveform by exploiting frequency domain measures and amplitude measures in the time domain. The technique is motivated by the difficulties posed by time domain analysis and by the consequent risks of inconsistencies on the part of both researchers and time based algorithms. The results demonstrate ...

Full waveform recording is becoming increasingly affordable and, consequently, available in today's state-of-the-art LiDAR systems. Therefore, there is no practical limitation to the complexity of pulse detection and other methods that can be applied in post-processing mode. Analyzing the entire return signal, the full waveform can provide additional geometrical and physical information about t...
