Abstract: A portable, single-fixation, magnetic derailment mitigation device may be fixed on a rail track for measuring the deflection of the rail track. The magnetically fixing device is used for measuring vertical track deflection (sleeper voids), horizontal track deflection, ambient and rail temperature, rail angle, vibration, displacement, and location. The derailment mitigation device sends digital notifications and/or alarms during the live train and/or freight operations to help prevent derailments, rail buckles, breaks, and pull apart. The measured data and/or all events obtained from the derailment mitigation device is stored in the data storage such as cloud storage and viewed from any smart devices.

Abstract: The disclosed systems and methods may receive a data record from either a legacy data source or a modern data source and determine whether the record satisfies a first set of validation rules. When the record fails to satisfy the first set of rules, reject the record for storage in a data store. When the record satisfies the first set of rules, determine whether the record satisfies a second set of validation rules. When the record satisfies the second set of rules, store the record in the data store with an indicator that the record satisfies the all rules. When the record fails to satisfy the second set of rules, if the source was a modern data source reject the record, and if the source was a legacy data source store the record in the data store with an indicator that it fails to satisfy the second set of rules.

Abstract: An automated system for detecting performance bugs in a program and for providing code recommendations to improve the performance of the program generates a code recommendation table from performance-related pull requests. The performance-related pull requests are identified in part from a classifier trained on semi-supervised data. A code recommendation table is generated from performance-related pull requests and is searched for similarly-improved code based on a set of difference features that includes structural and performance features of the before-code of a pull request that is not in the after-code.

Abstract: A word-sense disambiguation service may be performed to determine the semantic context of an ambiguous targeted word in an electronic data corpus. The word-sense disambiguation service may determine the semantic context of the words in the electronic data corpus by evaluating a main word and the context words surrounding the main word in a portion of text, then determine which context words are useful in defining the semantic context of the main word. The word-sense disambiguation service may then cluster the defining context words together and use the defining context words to train a word-embedding model to recognize the semantic context of an instance of the main word based on the proximity of the defining context words to the main word. A context-sensitive service may then receive input of a desired target word, then retrieve and display the various semantic contexts of the desired target word using the results gathered by the word-sense disambiguation service.

Abstract: Systems and methods for controlling access to wireless gaming devices and networks are provided. For example, access is controlled through one or more levels of security checks, such as a hard security check instead of or in addition to a soft security check. In a hard security check, the user employs an apparatus such as a card or other physical token that can be used to access the wireless gaming device. Such an apparatus may communicate information that identifies the user to the device or may simply be used to produce a signal without which the device is locked to users. The apparatus may further emit a time varying signal to enhance security.

Abstract: A firmware is configured with a firmware management protocol (“FMP”) capable of updating a firmware logo image and a firmware logo image volume is defined within a firmware for storing a firmware logo image. A firmware logo image updater executing on a computing device receives a UEFI capsule that contains a firmware logo image. The firmware logo image updater stores the UEFI capsule in a UEFI system partition on a computer-readable storage medium accessible to the computing device. Upon a reboot of the computing device, the FMP is executed. The FMP retrieves the UEFI capsule from the UEFI system partition. The FMP then updates the firmware logo image volume with the firmware logo image stored in the UEFI capsule.
