A retrospective study recently showed that oocytes presenting with a high birefringence of the inner zona layer were more often associated with conception cycles. To further investigate these findings, a prospective study was conducted between September 2005 and September 2006 including intracytoplasmic sperm injection (ICSI) cycles presenting with at least(More)
Recent studies using polarized light microscopy revealed a correlation between the presence of a spindle in human metaphase II meiotic oocytes and the fertilization rate following intracytoplasmic sperm injection (ICSI). Using a new spindle imaging system, it was possible to visualize the spindle image and the conventional light microscopic view of the(More)
In this paper the modeling of a signal by a chaotic generator with respect to a specified signal statistic will be considered. To accomplish that, the considered class of n-dimensional piecewise linear Markov generators will first be analyzed analytically, yielding an algebraic expression for the statistical quantity in question. Based on this analytical(More)
In classical speech synthesis linear systems are used to achieve the required spectral properties 1]. Figure 1 shows a simpliied discrete-time model of speech synthesis which is used e.g. in Linear Predictive Coding (LPC). It contains two signal sources (a pulse train generator for voiced speech and a white noise generator for unvoiced speech), an ampliier(More)
