Abstract: Systems, methods, articles of manufacture, and computer program products to: train a prediction model using a machine learning process, the prediction model configured to estimate whether further application of a hyperparameter tuning technique will cause an improvement in at least one of the hyperparameters; select the hyperparameters using the tuning technique; apply the prediction model to determine if further adjustment of the hyperparameters is likely to improve the success metric; and terminate the tuning technique when: accuracy of the prediction model in predicting improvement in a hyperparameter is above a predetermined accuracy threshold, and the prediction model predicts that further application of the tuning technique will not result in an improvement to the hyperparameter; or the accuracy of the prediction model in predicting improvement in the parameter is below the predetermined accuracy threshold, and an accuracy of hyperparameter adjustment is determined to be below a predetermined adjustment

Abstract: Various embodiments are directed to a system that utilizes regular expression (regex) to recognize at least portions of characters, words, text, numbers, etc. in a structured or unstructured dataset, any patterns associated therewith, and/or similarities between the determined patterns. In examples, a regex-based pattern recognition platform may receive a dataset and determine whether at least a first regex pattern and a second regex pattern can be identified. The occurrences of the first and second regex patterns and the frequency of those occurrences may reveal something about the dataset itself or any patterns contained therein.

Abstract: Provided herein is a method of and system for processing an optical fiber. The method includes the steps of drawing an optical fiber in a drawing direction along a process pathway through a coating chamber comprising an inlet and an outlet, and a coating liquid volume to coat the optical fiber; supplying the coating liquid through the inlet, the coating liquid exiting the coating chamber through the outlet; and recirculating to coating liquid exiting the coating chamber to the inlet.

Abstract: Opening and closing a door without the use of one's hands is facilitated. For instance, an apparatus can comprise one or two rotatable rings. For a one ring apparatus, the ring can have an opening so that the inner cross section of the opening of the ring can be pushed with a forearm or knee so that the ring will rotate and the person can then pull on the ring with his/her forearm or knee to open the door. In a two-ring apparatus, two adjacent rings, both with openings, can comprise similar push surfaces. When pushed on the pushed surfaces, the rings will rotate and the cross sections of the openings of the rings come into contact with one another, creating a surface against which a forearm or knee can pull on to open the door. A rotation plane converter can turn a doorknob using the apparatus.

Abstract: A tracheostomy airway device is provided comprising an outer cannula (110) having open proximal and distal ends, an inner actuation member insertable into the proximal end of the outer cannula, and one or more retention members (130). The one or more retention members are movable relative to the outer cannula between a retracted configuration in which the tracheostomy device is insertable into, and removable from, the trachea of a patient, and an extended configuration in which the one or more retention members impede removal of the tracheostomy airway device from the trachea. The retention members are operably linked to the inner actuation member or the outer cannula, such that movement of the inner actuation member relative to the outer cannula actuates movement of the one or more retention members between the retracted configuration and the extended configuration.

Abstract: A method of applying a coating liquid to an optical fiber is described. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.
