Abstract: The invention is a training method for training a system adapted for aiding evaluation of a medical image, during which a processing unit, an annotator unit, and an auxiliary unit for generating pseudo images are trained by independent pre-trainings. In a first cycle transferring data packets obtained by applying processing and annotator units on pseudo images and lesion location data packets corresponding to pseudo images to ROC unit, AUC parameter is determined. In a further cycle, building an AUC of the first cycle into joint-training loss functions of the processing unit and the annotator unit. The method further comprises training the joint-training functions of the processing unit and the annotator unit. The method further comprises applying the processing unit and the annotator unit on the pseudo images based on the lesion location data packets such that AUC is determined.

Abstract: A method is presented for connectivity checking and detection of connectivity failure, based on a modified Ethernet ARP address resolution mechanism to detect broken connectivity on physical, data-link and network layer between a first and a second node. The detection mechanism uses Periodical Gratuitous ARP messages (PGARP). PGARP messages are sent by a first node, the sender host or Issuer. On the other side of a data path is a second node, receiver host or Listener configured to detect lost connectivity by means of missing PGARP messages. The process on the Listener then informs subscribing services, host local, or remote, about the state of the connectivity.

Abstract: A method and arrangement in a wireless communication network for optimizing data rates when communicating layered multicast data. In an initial probing phase, the receiving capability of each user equipment (UE) in each cell is collected. The optimal data rate for each layer is then calculated and packets are transmitted to the UEs at the optimal rates. The UEs may periodically send updated receiving capabilities so that the optimal data rates can be updated. Additionally, the network may periodically obtain the updated receiving capabilities through secondary probing at unused data rates.
