Abstract: A downhole injector apparatus for injecting a taggant into a wellbore includes an injector nozzle outlet and a taggant reservoir in fluid communication with the injector nozzle outlet and configured to hold the taggant to be injected. The apparatus further includes a pressure wave generator configured to apply a pressure wave within the reservoir to expel the taggant from the reservoir through the injector nozzle outlet.

Abstract: According to examples there may be provided a method for classifying a capnogram, the method comprising: obtaining a breath waveform from a capnogram determining one or more transition points of the breath waveform, wherein the transition points comprise: a delta transition point between an expiratory baseline and an expiratory upstroke, a gamma transition point between an inspiratory downstroke and an inspiratory baseline, and an alpha transition point between the expiratory upstroke and an expiratory plateau; extracting features of the breath waveform using the transition points; and applying a trained machine learning model to the extracted features, wherein the trained machine learning model is configured to output a classification of the capnogram from the features.

Abstract: A Multi-Access Edge Computing (MEC) device, associated with a base station, may include a processor configured to receive a request to send data to a plurality of user equipment (UE) devices. The MEC device may be further configured to determine that the data is to be delivered to the plurality of UE devices by the base station via multicast; determine signal quality values for the plurality of UE devices; select a subset of the plurality of UE devices based on the determined signal quality values; and send, using the base station, the data to the selected subset of the plurality of UE devices via multicast, and delaying or terminating delivery of the requested data to UE devices, of the plurality of UE devices, that are not in the selected subset.
