Abstract: In some examples, a computing device may determine a replication criteria for replication of user information and/or resource information between a first computing site and a second computing site. The computing device may perform the replication between the first computing site and the second computing site based on the replication criteria. Further, the computing device may determine at least one of a user correspondence or a resource correspondence between the first computing site and the second computing site based on performing the replication. The computing device may replicate permission information between the first computing site and the second computing site based at least on the user correspondence and/or the resource correspondence.

Abstract: A water leakage position estimation system(S) configured to estimate a water leakage position in a pipe network including a plurality of pipe routes includes a water leakage determination unit (11) and an estimation unit (12e). The water leakage determination unit (11) determines whether a water leakage occurs in the pipe network based on a measured value of a vibration related to the pipe network that is acquired by a water leakage sensor (2) provided in the pipe network. The estimation unit (12e) estimates, when the water leakage determination unit (11) determines that a water leakage occurs in the pipe network, a pipe route in which the water leakage occurs from the plurality of pipe routes based on the measured value and a predicted value of the vibration for each pipe route acquirable by the water leakage sensor (2) when a water leakage occurs in each pipe route.

Abstract: Provided is a design support device capable of effectively utilizing defect knowledge in design work and reducing man-hours required for precise examination of a presented analysis result and variation depending on an individual user. A design support device that evaluates a defect that can occur in a design model generated by a design tool and a factor of the defect is configured to include a causal model database that stores a causal model expressing a defect that can occur in a design target by using a causal relationship in which, due to a certain phenomenon, another phenomenon occurs, an attribute information extraction unit that extracts attribute information regarding a design target from the design model, and a relevance degree evaluation unit that extracts, for the causal model, a causal relationship including a content matching with the extracted attribute information as a causal relationship having a high relevance degree to the design model.

Abstract: An abnormality detection system detects an abnormality in equipment using a machine learning model constructed by federated learning. The system comprises multiple computers that further include an initial model training unit configured to construct an initial training model based on input data, a device ID generation unit configured to generate a device ID for uniquely identifying each computer, a latent variable generation unit configured to generate a latent variable to be input to a model, a pseudo data generation unit configured to generate pseudo data for each of the plurality of computers, and a shared model training unit configured to construct a shared model which is a conditional generative model based on the pseudo data. These computers also include multiple abnormality detection devices configured to detect an abnormality in equipment by calculating an abnormality degree of the equipment based on the input data.

Abstract: A distributed transaction management device records a transaction settlement result log indicating a settlement result of a transaction in the distributed transaction system. When the distributed transaction management device receives a rollback processing completion notification from any one of multiple resource management units participating in the transaction, the distributed transaction management device deletes the transaction settlement result log of the rollback.
