This study explores ICESat/GLAS waveform data in Thuringian Forest, a low mountain range located in central Germany. Lidar remote sensing has been proven to directly derive tree height as a key variable of forest structure. The GLAS signal is, however, very sensitive to surface topography because of the large footprint size. This study therefore focuses on forests in a mountainous area to asses...

CogWave is a free and open-source software platform aiming at developing cognitive radio waveforms. Combining CogWave with USRP gives a rapid prototyping platform for physical layer design and algorithm validation through a realtime video, audio and text transmission. This paper presents the cognitive blind orthogonal frequency division multiplexing (OFDM) waveform implemented in the CogWave so...

The voiced speech waveform may be synthesized by exciting an LPC vocal tract filter with a pulse waveform patterned after naturally occurring glottal airflow pulses. Such a pulse waveform may be generated by computing samples of a piecewise polynomial curve at equally spaced time intervals. In this type of synthesis, the pitch period is commonly restricted to an integer multiple of the sample i...

At present, with the progress and innovation of technology, the radar communication dual function wave has become a hot research at home and abroad. Excellent integrated waveform can make full use resources of combat platform, reduce the size of equipment, and realize the actual functionality of the reality of the battle-field without affecting the radar communication function. The MSK-LFM dual...

Change of globe surface height is an important factor to study human living environment. The Geoscience Laser Altimeter System (GLAS) on ICESat is the first laser-ranging instrument for continuous global observations of the Earth. In order to have a comprehensive understanding of full-waveform laser altimeter, this study simulated the operating mode of ICESat and modeled different terrains’ (pl...

Waveform Relaxation method (WR) is a distributed algorithm to solve Ordinary Differential Equations (ODEs). In this paper, we propose a new distributed algorithm, named Waveform Transmission Method (WTM), by virtually inserting waveform transmission lines into the dynamical system to achieve distributed computing of ODEs. WTM is convergent to solve linear SPD ODEs.

OBJECTIVES The purpose of this study was to compare the effects of biphasic defibrillation waveforms and conventional monophasic defibrillation waveforms on the success of initial defibrillation, postresuscitation myocardial function and duration of survival after prolonged ventricular fibrillation (VF). BACKGROUND We have recently demonstrated that the severity of postresuscitation myocardia...

A commercially available six-dimensional (6D) motion system was assessed for accuracy and clinical use in our department. Positional accuracy and respiratory waveform reproducibility were evaluated for the motion system. The system was then used to investigate the dosimetric consequences of respiratory waveform variation when an internal target volume (ITV) approach is used for motion managemen...

This paper discusses a non-standard technique for timedomain waveform synthesis. In Extended Waveform Segment Synthesis sound is described as a structure of blocks of amplitude micro-fluctuations. These structures can be updated during synthesis or different structures can be combined generating dynamic evolving waveforms. This technique is intended to be: first, an extension of the existing li...
