Abstract: The disclosure provides a method of dehydrogenating hydrocarbons, such as C2 or C3 hydrocarbons, selectively and efficiently, to provide the corresponding alkylenes. The method is based on a Pt nanolayer catalyst over MXene (Pt/MXene) that shows resistance to coke deposition. The dehydrogenation conditions developed provided about 22% propane conversion and over 90% selectivity toward the desired propylene product, and the catalyst was stable for a 24-hour continuous run. The byproducts were ethane, ethylene, and methane, and only trace amounts of coke deposition over the catalyst were detected. Similar dehydrogenation conditions provided about 18% ethane conversion and over 90% selectivity toward the desired ethylene product. A mass balance of greater than 96% was achieved in each case.

Abstract: A computer-implemented method, system and computer program product for providing high quality speech recognition. A first speech-to-text model is selected to perform speech recognition of a customer's spoken words and a second speech-to-text model is selected to perform speech recognition of the agent's spoken words during a call. The combined results of the speech-to-text models used to process the customer's and agent's spoken words are then analyzed to generate a reference speech-to-text result. The customer speech data that was processed by the first speech-to-text model is reprocessed by multiple other speech-to-text models. A similarity analysis is performed on the results of these speech-to-text models with respect to the reference speech-to-text result resulting in similarity scores being assigned to these speech-to-text models.

Abstract: An approach is provided in which a system receives a first meme sent from a first user that is targeted to a second user. The system transforms the first meme into a second meme based on analyzing the first meme against a first user profile data corresponding to the first user and a second user profile data corresponding to the second user. The transforming includes replacing at least one element of the first meme with a second element in the second meme. The system, in turn, sends the transformed second meme to the second user.

Abstract: One or more frames within a video are segmented and classified according to information type. At least a portion of the information in the one or more frames is determined to be obscured. In response to this determination, information from audio data and the unobscured portion of the one or more frames is extracted.
