In this work, we investigate the relative contribution of the short-time magnitude and phase spectra towards speaker dependent information. The effect of the analysis window function type is also examined. For this purpose we conduct a human speaker verification experiment that uses phase-only and magnitude-only stimuli. The stimuli are constructed using the analysis-modification-synthesis proc...

This paper describes investigations into the use of ‘excitationsynchronous’ spectral analysis to provide acoustic features for automatic speech recognition. Within each 10 ms frame the region of maximum power is located and used as the centre for the window in a subsequent Fourier transform. The method has been found to be effective in locating stop bursts and vocal-tract responses to glottal c...

System states space based on Kripke structure can be exhausted by model checking, thus system key property described by temporal logic can be automatically verified. Presently model checking has been widely used in hardware validation and network protocol analysis. Sliding window protocol is a classical receive-send protocol, which is used in TCP/IP protocol group. In this paper, we propose the...

There are no doubts. We owe wavelet analysis to Jean Morlet. How did Morlet discover wavelets? Here is the story. During the late seventies Morlet was working as a geophysicist for the Elf-Aquitaine company. He had to process the backscattered seismic signals which carry the information related to the geological layers. These seismic signals present transient patterns. Processing such signals w...

In many signal processing applications, such as EEG analysis, the non-stationary signal is often required to be segmented into small epochs. This is accomplished by drawing the boundaries of signal at time instances where its statistical characteristics, such as amplitude and/or frequency, change. In the proposed method, the original signal is initially decomposed into signals with different fr...

In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...

People can estimate numerical quantities, like the number of grapes in a bunch, using the Approximate Number System (ANS). Individual differences in this ability (ANS acuity) are emerging as an important predictor in research areas ranging from math skills to judgment and decision making. One commonly used ANS acuity metric is the size of the Numerical Distance Effect (NDE): the amount of savin...

Cognitivism has dominated mainstream psychology for decades, but lately its position has been weakened. It has been criticized not only by behavior analysts but also by social and evolutionary psychologists, neuroscientists, and authors who are or used to be cognitivists themselves. At the same time, psychologists and neuroscientists in several fields are now rediscovering the necessity of unde...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

Since the overall quality of Taiwanese university education has been decreasing in recent years, and universities are losing their competitive advantage while facing foreign countries’ education systems and the threat of closing, upgrading innovation performance and improving total quality performance (Inno-Qual performance) so as to enhance overall operational performance have become an urgent...
