Abstract: The present invention generally relates to an emotion recognition and notification system comprises an input unit includes a camera for capturing a facial image of a user's face; a pre-processing unit to remove noise and enhance the details of the captured facial image; a face detection unit to detect a face from the captured facial image; a features extraction unit to extract a set of image features from detected face from the captured facial image; a central processing unit equipped with a two channel facial expression recognition network based on CNN and LSTM to recognize an emotion of a user upon comparing the set of image features from a pre-stored image features; and a control unit equipped with a communication module to alert a registered user about a recognized emotion.

Abstract: Disclosed herein is a mixture of at least one semi-aromatic polyamide A) and at least one semi-aromatic polyamide B), both containing repeat units derived from terephthalic acid. Further disclosed herein are a polyamide molding composition including said mixture of polyamides, a molded article produced from said polyamide molding composition and a method of using the mixture of semi-aromatic polyamides for the production of a molded article with improved mechanical properties, in particular with improved weld line strength.

Abstract: A drift bar is lowered into a well. The drift bar has a density that is less than a density of a wellbore fluid residing in the well. A tubular is lowered into the well below a surface level of the wellbore fluid residing in the well. The tubular defines an inner bore having an inner diameter that is greater than an outer diameter of the drift bar. The drift bar is positioned to pass through the inner bore of the tubular as the tubular is lowered into the well. After the tubular is positioned below the surface level, an absence or presence of the drift bar floating at the surface level is detected. An absence or presence of a restriction in the inner bore of the tubular is determined in response to detecting the presence or absence, respectively, of the drift bar floating at the surface level.
