Abstract: A computer-implemented method for managing operation of an application includes: authenticating a user of the application or a user device associated with a user of the application; and establishing a session with the application and enabling access to the application for the user if the user or the user device is authenticated. The method further includes determining, after the user or the user device is authenticated, whether the user or the user device is or remains present. The method further includes maintaining the session and the enabling of access to the application if it is determined that the user or the user device is or remains present; and terminating the session and disabling access to the application if it is determined that the user or the user device is absent for a predetermined duration.

Abstract: A system and a method of calibrating a plurality of digital imaging sensors with different modality for image fusion, comprising the steps of calibrating each digital image generated by a corresponding digital imaging sensor with one or more intrinsic parameters; scaling each digital image at a scaling ratio to generate a scaled digital image which has an overlapping region of interest; cross referencing one or more scaled digital images to derive one or more extrinsic parameters; calibrating each digital imaging sensor with the extrinsic parameters; and transforming and rectifying each digital image such that the region of interest of each digital image is coplanar and aligned.

Abstract: A computer-implemented method for training a natural language translation model. The computer-implemented method includes: processing one or more sets of electronic parallel documents to obtain a plurality of aligned parallel sentences; creating a first training set including a subset of the plurality of aligned parallel sentences; and training the natural language translation model in a first stage using the first training set. The computer-implemented method further includes: modifying the first training set based on translation errors detected after the first stage of training; creating a second training set based on the modified first training set and at least some of the plurality of aligned parallel sentences not in the first training set; and training the natural language translation model in a second stage using the second training set so as to improve translation performance of the natural language translation model.
