Abstract: Embodiments utilize distributed ledger technology (e.g., blockchain) to handle interaction flows for processes occurring between separate/distinct systems. A first system initiates an interaction flow, creating a first ledger entry (e.g., blockchain transaction) based upon an original timestamp and encryption keys. The interaction flow is then communicated across a boundary of the first system to a second system. The second system receives the interaction flow, and creates a second ledger entry (e.g., second blockchain transaction in the blockchain) based upon a subsequent timestamp and hash of the first ledger entry. Further cross-system interactions are similarly handled by creating additional immutable ledger entries (e.g., more blockchain transactions in the blockchain). Thus, the stored interaction flows serve as the single source of truth for communication across system boundaries.

Abstract: Systems, methods, and computer media for blockchain-based communication between applications are provided herein. Using a blockchain-based multi-application communication platform, different applications can create and interact with trusted records. A trusted record represents something quantified and/or tracked through an application. Trusted records are stored in a blockchain. Trusted records can be created by one application and accessed by other applications through the platform. Interactions of the different applications with a trusted record are also stored in the blockchain. The immutability of information stored in the blockchain ensures that the trusted records can in fact be trusted, ensures that interactions with trusted records are memorialized, and removes uncertainty as to which application's records are correct.

Abstract: Techniques and solutions are described for facilitating collaborations between entities. A hub computing system is provided that is accessible to multiple client systems. The hub computing system can be used to create instances of collaboration entities, which can be of various defined types. Object instances can be created and included in, or referenced by, the collaboration entity instances. Clients may take various actions with respect to a collaboration entity instance using one or more hub services. At least a portion of the actions taken with respect to a collaboration entity instance can be recorded in a blockchain. The blockchain records can be used to verify actions taken with respect to a collaboration entity instance, and to verify the integrity of collaboration entity instances.

Abstract: A cover device for at least partially closing an underwater opening in a hull of a watercraft includes a variable-volume hollow-chamber lip assembly including at least two hollow-chamber lips and one buoyancy body. The at least one hollow-chamber lip is volume-variable by supplying a fluid to or removing a fluid from an interior thereof, and the at least one hollow-chamber lip assembly is shiftable between an expanded state and a contracted state by supplying or removing the fluid.

Abstract: The invention relates to a cover device for at least sectional closing of an underwater opening in a hull of a watercraft, in particular an opening of a transverse channel of a thruster. According to the invention the cover device includes at least one variable-volume hollow chamber lip including at least one buoyancy body, and the at least one hollow chamber lip is shiftable into an expansion state or into a shrinkage state by supplying or removing a fluid, in particular air. As a result of the variable-volume or inflatable cover device a more reliable and simultaneously lower-maintenance operation of the cover device is given. In addition, the invention has a thruster, in particular a bow or stern-thruster, as subject matter.

Abstract: Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for receiving, from a first computing device, a request for a transaction to be executed during a cooperative effort, the request requesting resources, each resource being associated with an amount of digital currency, receiving, from a second computing device, a response to the request, the response indicating that a second entity at least partially fulfills the request, recording the request and the response in a DLS, each of the first computing device and the second computing device communicating with the DLS, logging the request and the response in respective resource planning systems of the first entity and the second entity, the resource planning systems communicating with respective nodes of the DLS, and, upon ending of the cooperative effort, facilitating reconciliation between the first entity and the second entity based on transaction data recorded in the DLS.

Abstract: A fin stabilizer for stabilizing watercraft includes a pivotable stabilizer fin and a receiving space for receiving the stabilizer fin. The stabilizer fin is shiftable from a retracted state in which the stabilizer fin is received in the receiving space to an extended state in which the stabilizer fin extends from the receiving space. Also at least one flexible cover element for at least partially covering an opening of the receiving space, through which opening the stabilizer fin enters and exits the receiving space during retracting and extending, respectively. The stabilizer fin does not contact the at least one cover element when shifting from the retracted state to the extended state.

Abstract: Methods and apparatus, including computer systems and program products synchronizing a displayname and a resource identifier. In one technique, a machine-implemented method includes receiving input corresponding to a displayname of a data resource; preparing a resource identifier of the data resource within a repository based on the input and naming conventions associated with the repository; and preparing the displayname of the data resource based on the input. The resource identifier may be prepared such that the resource identifier resembles the displayname. Naming conventions may include a naming convention that requires a content-type extension to be retained by a resource identifier. The displayname may be presented to a user interface such that only the displayname is displayed and a corresponding resource identifier is excluded from being displayed.
