In this episode, we present the all-new PMI F166 Series with IO-Link. This compact inductive positioning system features a metal housing and an IO-Link interface that can be used to set the detection range and switch points/windows and allows direct access to process data and value-added data such as error messages. We will also review the other IO-Link models in our PMI offering and discuss their possible applications.See omnystudio.com/listener for privacy information.

The new Performance Line IO-Link rotary encoders include all the features of the Pure Line series and add shaft velocity measurement and critical shaft velocity and maintenance alerts. The Performance Line devices are available in a 36 mm or 58 mm housing, with solid or recessed hollow shaft and up to IP67 degree or protection. The new 36 mm and 42 mm HT series rotary encoders feature our rugged IP69K-rated heavy-duty housing with a high shaft load capacity of 270 N. The HT series has all the IO-Link features of the Pure Line series and is perfect for use in harsh environments, such as car washes or areas where regular washdowns are required.See omnystudio.com/listener for privacy information.

This thesis is concerned with the rhythmical structure of speech under the influence of alcohol. All analyses presented are based on the Alcohol Language Corpus, which is a collection of speech uttered by 77 female and 85 male sober and intoxicated speakers. Experimental research was carried out to find robust, automatically extractable features of the speech signal that indicate speaker intoxication. These features included rhythm measures, which reflect the durational variability of vocalic and consonantal elements and are normally used to classify languages into different rhythm classes. The durational variability was found to be greater in the speech of intoxicated individuals than in the speech of sober individuals, which suggests, that speech of intoxicated speakers is more irregular than speech of sober speakers. Another set of features describes the dynamics of the short-time energy function of speech. Therefore different measures are derived from a sequence of energy minima and maxima. The results also reveal a greater irregularity in the speech of intoxicated individuals. A separate investigation about speaking rate included two different measures. One is based on the phonetic segmentation and is an estimate of the number of syllables per second. The other is the mean duration of the time intervals between successive maxima of the short-time energy function of speech. Both measures denote a decreased speaking rate in the speech of intoxicated speakers compared to speech uttered in sober condition. The results of a perception experiment show that a decrease in speaking rate also is an indicator for intoxication in the perception of speech. The last experiment investigates rhythmical features based on the fundamental frequency and energy contours of speech signals. Contours are compared directly with different distance measures (root mean square error, statistical correlation and the Euclidean distance in the spectral space of the contours). They are also compared by parameterization of the contours using Discrete Cosine Transform and the first and second moments of the lower DCT spectrum. A Principal Components Analysis on the contour data was also carried out to find fundamental contour forms regarding the speech of intoxicated and sober individuals. Concerning the distance measures, contours of speech signals uttered by intoxicated speakers differ significantly from contours of speech signals uttered in sober condition. Parameterization of the contours showed that fundamental frequency contours of speech signals uttered by intoxicated speakers consist of faster movements and energy contours of speech signals uttered by intoxicated speakers of slower movements than the respective contours of speech signals uttered in sober condition. Principal Components Analysis did not find any interpretable fundamental contour forms that could help distinguishing contours of speech signals of intoxicated speakers from those of speech uttered in sober condition. All analyses prove that the effects of alcoholic intoxication on different features of speech cannot be generalized but are to a great extent speaker-dependent.

Based on a straightforward physical model, a new lightning parameterization has been developed: A two-plate capacitor represents the basic dipole charge structure of a thunderstorm, which is charged by the generator current and discharged by lightning. In this approach, the generator current as well as the discharge strength are parameterized using the graupel-mass field. If these two quantities are known, and if the charging and discharging are in equilibrium, then the flash rate is uniquely determined. This approach remedies shortcomings of earlier theoretical approaches that relate the flash rate e.g., to generator power. No distinction is made between intracloud and cloud-to-ground discharges. In order to test this approach, polarimetric radar data were used, from which the graupel distribution in observed thunderstorms could be inferred. The lightning activity was detected using the LINET network. The comparison between theoretically-predicted and measured flash rates is encouraging: Over a wide range of flash rates, the theoretical approach yields accurate results for isolated thunderstorms. Two existing parameterizations, which only use the depth of the clouds as predictor, produce substantially less accurate forecasts. These two existing approaches, the one developed in this study, as well as a fourth one based on updraft velocity, were implemented in the convection-resolving COSMO-DE numerical weather prediction model. With this model, real-world convective scenarios were simulated. The output of the lightning scheme includes the location and time of every simulated discharge. Testing the performance of the parameterizations with modeled convection is difficult as there is no one-to-one correspondence between observed and modeled convective clouds. Where a comparison between modeled and observed flash rates of individual clouds was possible, the results for individual cells were promising. The comparison of the bulk lightning activity over an area comprising southern Germany and adjacent countries suggests that none of the four parameterizations captures the overall lightning activity well. This is mainly because COSMO-DE does not simulate the observed number of cells at the correct times.
