Abstract: Devices and techniques for data removal marking in a memory device are described herein. A delete command can be received at the memory device. A count of data portions in the delete command can be compared to determine whether the count is below a threshold. In response to determining that the count of data portions is below the threshold, the data portions can be written to a buffer. When a buffer full event is detected, a segment of an L2P data structure can be loaded into working memory of the memory device. Then, each record in the segment of the L2P data structure that has a corresponding entry in the buffer can be updated to mark the data as removable (e.g., invalid).

Abstract: Embodiments described herein provide various examples of real-time visual object tracking. In another aspect, a process for performing a local re-identification of a target object which was earlier detected in a video but later lost when tracking the target object is disclosed. This process begins by receiving a current video frame of the video and a predicted location of the target object. The process then places a current search window in the current video frame centered on or in the vicinity of the predicted location of the target object. Next, the process extracts a feature map from an image patch within the current search window. The process further retrieves a set of stored feature maps computed at a set of previously-determined locations of the target object from a set of previously-processed video frames in the video. The process next computes a set of correlation maps between the feature map and each of the set of stored feature maps.

Abstract: Aspects of the present disclosure relate to dispersing graphene oxide in a fluid and washing a first electronic part with cleaning fluid. Aspects of the present disclosure relate to testing cleaning fluid for a concentration of ions, and determining whether the ion concentration is below a threshold. If the ion concentration is below a threshold level, continuing to wash parts with the fluid. If the ion concentration is above a threshold level, replacing the cleaning fluid.

Abstract: Automated methods and systems described herein are directed to identifying potential root causes of a problem in a data center. Methods and systems receipt an alert or other notification of a problem occurring in a data center and a time when the problem was noticed. A search window is created based on the time and a stream of log messages generated in the search window is converted into a time dependent metric. An anomaly detection technique is applied to the metric to determine a start time of a problem. Logging events and key phrases in the log messages are identified in the search window and presented as potential root causes of the problem. The potential root cause may then be used by system administrators and/or tenants to diagnose the problem and execute remedial measures to correct the problem.
