Publication number: 20250125975Abstract: In a Byzantine computing environment in which a database is sharded or partitioned among multiple clusters of computing nodes, consensus for and execution of data transactions (e.g., transactions that require and/or affect data of one or more shards) are achieved in a resilient manner. Within some clusters, multiple primary replicas concurrently propose transactions for processing in parallel by all replicas. For some multi-shard transactions, shards involved in the transactions may be logically ring-ordered; each shard in turn achieves consensus among its nodes to commit the transactions, and then executes its portion of the operation after consensus is obtained among all shards. For some other multi-shard transactions, involved shards first determine whether local data constraints are satisfied, after which data modifications are made in parallel.Type: ApplicationFiled: December 20, 2024Publication date: April 17, 2025Applicant: The Regents of the University of CaliforniaInventors: Mohammad Sadoghi Hamedani, Jelle Antonius Johannes Hellings, Suyash Gupta, Sajjad Rahnama

Publication number: 20120098335Abstract: The invention relates to a device and a method that can enable generators for producing electrical energy to be kept stable on the network during and following a line failure, such as a voltage dip. This requirement is defined in the network connection conditions of many network operators and must be observed for installations of a certain power. According to the invention, during a line failure, a load is inserted, enabling the energy that can no longer be supplied to the electric network due to the voltage drop to be absorbed by the load.Type: ApplicationFiled: March 12, 2010Publication date: April 26, 2012Applicant: Andritz Hydro GmbHInventors: Johann Hell, Nebojsa Danilovic

Patent number: 7372172Abstract: Arrangement for generating electrical power from a flowing medium, wherein the arrangement includes a plurality of turbine generator units. At least some of the plurality of generator units are arranged at least one of one above another and one beside another. At least some of the plurality of generator units are connected to one another to form at least one module. At least one of the plurality of generator units includes a synchronous generator having permanent magnetic poles for excitation. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.Type: GrantFiled: June 3, 2004Date of Patent: May 13, 2008Assignee: VA Tech Hydro GmbHInventors: Stefan Winkler, Günther Hess, Johann Hell, Friedrich Gillmeier
