Systems and methods are provided for implementing automated user interface testing with integrated machine learning models. Systems and methods for detecting and preemptively correcting flow path errors are disclosed. Systems and methods for minimizing user input and optimizing testing efficiency are disclosed. A result dashboard is disclosed in which testing results and errors are displayed and a user may interact with interactive testing reports.

A virtual machine (VM) has direct access to an I/O device having physical and virtual functions and a mailbox register, and includes a guest driver for controlling the virtual functions. The VM runs on system software that includes a physical driver for controlling the physical function (PF) and maintains VM page tables, which include an entry that references a memory space into which the mailbox register is mapped. The system software registers a callback function with the physical driver, which the physical driver invokes upon receiving a trigger for communication with the guest driver. In response, the system software alters the page tables so that access to the mailbox register causes a PF intercept, and the callback function handles the communication with the guest driver. After completion of the communication, the system software alters the page tables so that access to the mailbox register does not cause a PF intercept.

A core board, a server, a fault repairing method and apparatus, and a storage medium are provided. The server includes: a baseboard manager controller; and at least one core board connected to the baseboard manager controller, and configured to receive, when receiving a forced downloading signal from the baseboard manager controller, data for repairing from the baseboard manager controller to perform fault repairing.

Data retrieved from a portion of a device is obtained at a transmission buffer through an input/output (IO) cell of the device. The data is provided from the transmission buffer to a receiving buffer through the IO cell. The data is obtained from the receiving buffer. Responsive to a detection of a first mismatch between the data retrieved from the portion of the device and the data obtained from the receiving buffer, a fault is determined to have occurred at one or more of the transmission buffer or the receiving buffer.

A method for handling input/output (I/O) expansion power faults in a telematics device is provided. The method includes setting an I/O expander power-off duration to an initial value and powering on an I/O expander interface. In response to detecting a power fault at the I/O expander interface, the I/O expander interface is powered-off dur the power-off duration and the power-off duration is increased. If the power-off duration is greater than the power-off duration limit, the I/O expander interface is permanently powered-off. The steps are repeated until either the power fault does not recur, or the I/O expander interface is permanently powered-off.

Techniques are provided herein for pre-emptively reinforcing one or more buses of a computing device against the effects of signal noise that could cause a reduction in signal integrity. The techniques generally include detecting an event (or “trigger”) that would tend to indicate that a reduction in signal integrity will occur, examining a reinforcement action policy and system status to determine what reinforcement action to take, and performing the reinforcement action.

A method for ensuring data quality integrity on a magnetic tape includes the steps of writing object data to the magnetic tape; dividing the object data into a plurality of data chunks; generating a hash tree from the plurality of data chunks, the hash tree being formed in a plurality of levels, the hash tree including (i) a plurality of chunk hashes wherein a separate chunk hash is generated for each of the plurality of data chunks, and (ii) at least one second level hash that is generated from concatenation of at least two of the plurality of chunk hashes; and checking integrity of a first data chunk of the plurality of data chunks by evaluating at least one of the plurality of chunk hashes and the at least one second level hash.

A method for detecting abnormal transactional behavior in a financial account is provided. The method includes: accessing first information that includes a textual description of a first transaction of a plurality of transactions associated with a first account; analyzing the text by applying tags thereto; assigning, based on a result of the analyzing, the first transaction to a respective cluster of the plurality of transactions; and designating each respective cluster as corresponding to one from among a normal transactional behavior group, an abnormal transactional behavior group, and an anomalous transactional behavior group. When a proportion of abnormal and anomalous transactions exceeds a threshold, the account may be flagged for further investigation.

Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. Microservices on the transaction exchange platform may interact with the transaction objects based on configured workflows associated with the transactions. Processing on the transaction exchange platform may facilitate clearing and settlement of transactions. Some aspects may provide for dynamic and flexible reconfiguration of workflows and/or microservices. Other aspects may provide for data snapshots and workflow tracking, allowing for monitoring, quality control, and auditability of transactions on the transaction exchange platform.

A method for handling power faults in a primary electronic device is provided. The method includes setting a power-off duration to an initial value and powering on a hardware interface. In response to detecting a power fault at the hardware interface, the hardware interface is power-cycled by a plurality of power cycles having progressively increasing power-off durations until a limit is reached. A primary electronic device for carrying out the method is also provided. The primary electronic device includes a controller, a memory, and a hardware interface for coupling the telematics device to a secondary electronic device.
