    Opis:
    Charging operations of a compact Tesla transformer were experimentally investigated, in single-shot and rep-rate (50 pps for 1 s) modes, respectively. The charging limitations were also explored. The experimental results were compared and analyzed. The maximum secondary charging voltages of the Tesla transformer were measured to be 380 kV and 300 kV in single-shot and rep-rate modes, respectively. The RMS pulse-to-pulse instability of the secondary charging voltage is generally less than 10% but increases with the increasing initial voltage across the primary capacitor. Since the secondary capacitor of the Tesla transformer is a pulse forming line (PFL), continued operation is possible if there is breakdown in the PFL. Furthermore, operation can even be continued under occasional breakdown for some pulses, without the effects on the operations of subsequent pulses.

    Opis:
    This paper proposes a comprehensive study on machine listening for localisation of snore sound excitation. Here we investigate the effects of varied frame sizes, and overlap of the analysed audio chunk for extracting low-level descriptors. In addition, we explore the performance of each kind of feature when it is fed into varied classifier models, including support vector machines, k-nearest neighbours, linear discriminant analysis, random forests, extreme learning machines, kernel-based extreme learning machines, multilayer perceptrons, and deep neural networks. Experimental results demonstrate that, wavelet packet transform energy can outperform most other features. A deep neural network trained with subband Energy ratios reaches the highest performance achieving an unweighted average recall of 72.8% from four types for snoring.

    Opis:
    Germination can be used to enhance nutritional value and health functions of edible seeds. Sprouts are considered healthier than non-germinated seeds because they are richer in the basic nutritional components (protein, amino acid, carbohydrates, and minerals) and also contain more bioactive components. The present study is the first to dynamically analyze the germination properties regarding morphological characteristics, nutrient compounds, bioactive components and antioxidant activities of Firmiana platanifolia (F. platanifolia) seeds. The results showed that the appearance, color and morphology of F. platanifolia seeds and sprouts at different germination times showed considerable differences. With the increasing germination time, the moisture content, sucrose, fructose, total flavonoid content and DPPH significantly increased, and reached the peak at 8 d of germination, almost 2.38, 5.76, 4.02, 7.97 and 8.91 times higher than those of at 0 d, respectively. The soluble protein, total phenolic, ABTS and ferric reducing antioxidant power (FRAP) increased first and then decreased as the germination time increased, and were overall higher than those of at the initial concentration. However, total starch content and mineral elements decreased as germination progressed. Additionally, the total flavonoid content showed a strongly positive correlation with DPPH (p<0.01), whereas the total phenolic and total flavonoid content showed a similar, significant and positive correlation with ABTS and ferrous ion chelating activity (FICA, p<0.05). Therefore, seed germination significantly increased phytochemical contents and antioxidant activity. The current research results will help to reveal the dynamic changes in nutrient content and antioxidant activity of F. platanifolia seeds during the germination process, and provide reference data for further studying the development and utilization of germinated seeds.
