Abstract: Techniques are provided for dynamic alert suppression policy management. In one embodiment, the techniques involve receiving an event stream, wherein the event stream includes metric values comprising at least one of: log anomaly data and metric anomaly data, determining an anomalous event based on the event stream, determining a persistent region of the anomalous event, determining a quantum representation of the persistent region, determining X-Y values of the persistent region based on the quantum representation, and generating a policy based on a set of the X-Y values.

Abstract: The present disclosure is related to methods of screening for the onset or predisposition to the onset of or monitoring an esophageal or gastric neoplasm in an individual, said method comprising assessing the methylation status of a selected DNA region in a biological sample from said individual wherein a higher level of methylation of at least one of the DNA regions relative to control levels is indicative of an esophageal or gastric neoplasm or a predisposition to the onset of a esophageal or gastric neoplasm.

Abstract: Systems/techniques for generating training data via reinforcement learning fault-injection are provided. A system can access a computing application. In various aspects, the system can train one or more machine learning models based on responses of the computing application to iterative fault-injections determined via reinforcement learning. More specifically, the system can: inject a first fault into the computing application; record a resultant dataset outputted by the computing application in response to the first fault; train the one or more machine learning models on the resultant dataset and the first fault; compute a reinforcement learning reward based on performance metrics of the one or more machine learning models and based on a quantity of the resultant dataset; update, via execution of a reinforcement learning algorithm, the fault-injection policy based on the reinforcement learning reward; and inject a second fault into the computing application, based on the updated fault-injection policy.

Abstract: A method of charge mitigation in additive layer manufacturing is provided, which uses a charged particle beam (103) to fuse metal powder (122) within a metal powder bed (123) to form a product layer-by-layer, the method comprising using a charged particle beam optical system to form a charged particle beam, to steer the charged particle beam to be incident on a powder bed of metal powder and to scan over the powder bed to fuse powder into a desired layer shape. While steering the charged particle beam, the method comprises using a neutralising particle source (160) to generate neutralising particles of an opposite charge to the charged particles in the vicinity of the charged particle beam such that the neutralising particles are attracted to the charged particles of powder in the powder bed. An additive layer manufacturing apparatus (100) is also provided.

Abstract: A dispensing and application apparatus designed to contain pre-measured amounts of a flowable substance. The apparatus comprises a compartment 130 for storing the substance that is partially enclosed by a frangible seal 210, an applicator 100, and an expandable chamber 170 designed to accept and dissipate the hydraulic force created when pressure is applied to the compartment 130, rupturing the frangible seal 210, and expelling the substance into the chamber 170. The applicator 100 is attached to the chamber 170 with an applicator bond area 180. The expandability of the chamber 170 is conferred by expandability of the applicator 100, and is varied in different embodiments by altering the ratio between the area of the applicator bond area 180 and the area of the applicator 100. The frangible seal 210, in one of many embodiments, may be a chevron shape stress riser 250 with a point of inflection 240 oriented towards the compartment 130. A removable cap may cover the applicator.

Abstract: A 3-D adaptive laser powder fusion welding system provides for both modeling/gauging of a workpiece as well as repair, restoration, and/or manufacture thereof. By providing a work platform and apparatus support system, five degrees of control in the form of two linear axes and three rotational axes are provided. The sixth linear axis is controlled via the displacement of a laser powder fusion (LPF) welding head and a laser rangefinding head. The laser rangefinding head system enables the workpiece W to be modeled electronically or otherwise. Additionally, the rangefinding system enables a model part to serve as a template from which repairs or construction are affected. The LPF welding head then affects any repairs or manufacture that are needed on the workpiece W. The LPF welding head is powered by filler material. The entire system is generally controlled by computer which enable the operator to be separated from a generally hot and hostile welding environment.
