Abstract: In some implementations, an utterance that requests a voice call is received, the utterance is classified as spoken by a particular known user, the particular known user is determined to be associated with a personal voice number, and in response to determining that the particular known user is associated with a personal voice number, the voice call is initiated with the personal voice number.

Abstract: Quantitative rating systems and techniques are described that prioritize customers by propensity to buy and buy size to generate customer ratings. In one example, a propensity model is used to determine a likelihood of a potential customer to purchase a product, and a projected timeframe buy size for the potential customer is determined. An expected value for the potential customer is generated by combining the likelihood of the potential customer to purchase the product and the projected timeframe buy size. In another example, a ratio model of annualized recurring revenue (ARR) is used to determine a timeframe buy size for an existing customer in consecutive time frames. An upsell opportunity for the existing customer is determined based on the timeframe buy size less an ARR for a current time frame for the existing customer. A rating of the potential or existing customer is output in a user interface.

Abstract: The present invention provides a method of forming a self-rolled metallic nanosheet. The method includes providing a bendable polymeric substrate and forming a hydrogel-based separation layer on the bendable polymeric substrate. A thin-film metallic nanosheet is deposited on the hydrogel-based separation layer, the thin-film metallic nanosheet having a thickness of approximately 150 nm or less to form a nanosheet-hydrogel-polymer composite. Channel cracks are induced in the nanosheet-hydrogel-polymer composite. The hydrogel layer is swelled to delaminate the metallic nanosheet employing the induced channel cracks to form one or more nano-morphology structures selected from scroll morphology, ribbon morphology, spiral morphology, or helix morphology.

Abstract: The present invention belongs to the technical field of information, particularly relates to the theories such as time series interval prediction, extreme learning machine modeling and Gaussian approximation solution, and is a wind power output interval prediction method. First, interval prediction of wind power output influencing factors is realized by time series analysis and normal exponential smoothing so as to consider an input noise factor. Then an extreme learning machine prediction model is established with an interval result as an input, output distribution is calculated based on iterative expectation and a conditional variance law, and thus an interval prediction result of wind power output is obtained. The method has advantages in interval prediction performance and calculation efficiency and can provide guidance for production, scheduling and safe operation of a power system.
