Abstract: A method, comprising: obtaining a parsed trace log that is generated by parsing a raw trace log of a storage system, the parsed trace log identifying a first sequence of tasks that are executed as part of a same input-output (I/O) operation; classifying the first sequence of tasks by using a machine learning model, the first sequence of tasks being classified into one of a first category and a second category, the first category corresponding to anomalous events, and the second category corresponding to non-anomalous events; when the first sequence of tasks is classified in the first category: identifying an anomaly code that corresponds to the first sequence of tasks and generating an alert that is associated with the anomaly code, the anomaly code being identified based on a distance between the first sequence of tasks and a second sequence of tasks that is mapped to the anomaly code.

Abstract: Individual processors of a storage system are analyzed to determine which thread types are most important for servicing a run workload, where importance is measured by number of CPU cycles used. Permutations of differentiated access to CPU cycles are calculated, where the most important thread types are provided with greater access to CPU cycles than thread types of lesser importance. The permutations are tested with the same run workload to determine which permutation yields the greatest average IOPS. The thread scheduler for the processor is configured with that permutation.

Abstract: A method and a device for the precision turning of a workpiece made of a heat-treatable steel permits a dry hard precision turning of hardened workpiece surfaces without tempering. In order also to allow precision turning and hardening of unhardened workpiece surfaces which are simultaneous in terms of production time, use is made of the local temporary heating of the workpiece caused by machining. The workpiece surface is heated further locally by the action of a laser beam, in the region directly behind the cutter, up to the transformation temperature of the material to be machined via an optical fiber integrated in the tool. The surface is then self-quenched and, as a result, hardened close to the surface. At the same time, the surface temperature at the point of action of the laser beam can be recorded thermographically and, this actual temperature signal can be used to adjust the power of the laser beam so as to maintain the desired temperature.

Abstract: A device for induction heating of the inside of cylinder liners of reciprocating-piston engines to a transformation temperature, for the purpose of hardening. An inductor head is equipper with an aligning device designed as a spreadable cage which is equipped on the outside with clamping bars, clamping bosses a clamping shells which can be applied free from play and under the effect of force against the inner surface of the cylinder liner. The inductor loop is also displaced radially and brought into the working position by means of these clamping shells. Heating and hardening is carried out only with the inductor head in the clamped and exactly aligned state, whereas, after the clamping shells and the inductor loops have been released, a further indexed movement of the inductor head is possible. The work is carried out at relatively high alternating-current frequencies in the range between 400 and 500 kHz and at relatively high energy densities in the range above 5 kw/cm.sup.2 .

Abstract: A communication system for deaf, deaf-blind, or non-vocal individuals includes an instrumented glove for obtaining electrical signals indicative of a hand configuration of a first individual. Strain gage sensors in the glove flex with movement of the hand. Each sensor includes a tension strain gage and a compression strain gage which are serially connected and form two legs in a bridge circuit. Signals from the bridge circuit are amplified and digitized and applied to a computer which includes an adaptive pattern recognition algorithm which is responsive to hand-state vectors for recognizing letter beacons in hand-space. A second individual communicates with the first individual through the computer system using a portable keyboard. The output devices for communicating to the first and second individuals depend on the visual, vocal and hearing capabilities of the individuals and can be selected from a voice synthesizer, LCD monitor, or braille display.
