The present disclosure discloses a method and apparatus for controlling redundancy of a valve control system of a converter valve. The method includes: for each FPGA: in a case that the FPGA receives the on-duty state representing the active state: outputting a high-level control signal to a data selector through the FPGA; in a case that the FPGA receives the on-duty state representing the standby state: outputting a low-level control signal to the data selector through the FPGA, and maintaining a control signal output state of the FPGA and the other FPGA; and in a case that running state information of the other FPGA received by the FPGA through a monitoring output channel is a crash state: outputting a low-level signal to a control port of the other FPGA through the monitoring output channel by the FPGA.

A stator includes a stator core and a stator winding. An inner wall of the stator core is provided with M winding slots, the M winding slots are uniformly disposed in a circumferential direction of the inner wall of the stator core. The stator winding includes flat wire conductors inserted in the winding slots, N layers of flat wire conductors are disposed in any one of the winding slots, and phase units of a first-phase winding, phase units of a second-phase winding, and phase units of a third-phase winding are sequentially and periodically arranged along the inner wall of the stator core. Each phase winding includes P parallel branches. Any one of the parallel branches connects flat wire conductors of M·N/3P layers.

Stator, flat wire motor, powertrain, and vehicle

In one example method, a first image including M objects is obtained. For N objects in the M objects, when N is greater than or equal to 2, arrangement orders of the N objects is determined, where an arrangement order of any one of the N objects is determined based on at least one of a scene intent weight, a confidence score, or an object relationship score. The scene intent weight is used to indicate a probability that the any object is searched in a scene corresponding to the first image, the confidence score is a similarity between the any object and an image in an image library, and the object relationship score is used to indicate importance of the any object in the first image. Search results of some or all of the N objects are fed back according to the arrangement orders of the N objects.

Search result feedback method and apparatus, and storage medium

Disclosed is a framework for providing microservices for database with embedded container service in a container cloud platform. The framework includes a container cloud manager for performing distributed management of resources in a data center. The container cloud manager includes an orchestrator with a flexible job scheduler and operator pool. The flexible job scheduler and container cloud master form a flexible job management platform for managing jobs of the data center. The flexible job management framework can isolate various types of jobs as well as mix various jobs for efficient usage of hosts or resources in the data center. The operator pool includes optional components of a database. The orchestrator facilitates quick customization and release of database products, such as a HANA database with optional services, as requested by a user in the container cloud platform.

Methods, systems, and computer-readable storage media for receiving, by a service stack recovery engine, an error message indicating a failed service in a plurality of services executed in a cloud platform, determining, by the service stack recovery engine, a set of services for recovery in response to the error message, and, for each service in the set of services, identifying, by the service stack recovery engine, an error handler that is associated with a service recovery type in a set of service recovery types, the error handler including a set of error handling operations to be executed to recover the failed service, and transmitting, by the service stack recovery engine, the error handler to a service recovery agent associated with the respective service, the service recovery agent executing error handling operations of the error handler to recover the service.

Service stack recovery in cloud platforms

This application relates to a converter in a photovoltaic power generation system and a converter control method. An input end of the converter is connected to at least one photovoltaic module, and an output end is connected to an inverter. The control method includes: determining an output power-voltage (PV) curve of a converter based on an output PV curve of the photovoltaic module; and controlling a voltage output of the converter based on the output PV curve of the converter. The output PV curve includes at least a simulated voltage limiting section and a constant power section that are connected. In this application, an existing MPPT control policy of the inverter can be adapted when a voltage-limited output is implemented, to avoid a case in which a power of a photovoltaic string drops to zero.

Methods, systems, and computer-readable storage media for receiving, by an operation guard system executed within a cloud platform, session information representative of a session of a user within the cloud platform, the session information including user information and operation information, determining, by the operation guard system, that the user is signed into a technical group for execution of an operation represented in the operation information, and in response, providing, by the operation guard system, a risk score associated with the operation, and determining, by the operation guard system and at least partially based on the risk score, that the operation is a risk-oriented operation based on the risk score, and in response, preventing execution of the operation and transmitting an alert.

Intelligent trackable operation guard service in cloud platforms

In an example embodiment, a solution is used to provide container volume replication via a container storage replication log and volume buffer synchronization, which is built on top of a container cloud platform whose container metadata and replication runtime configuration are all managed by a storage manager (a service orchestrated by its job scheduler and service orchestrator). This container volume replication ensures the data security for a long-running service in the container. In the case of any disaster, the in-memory database and application data inside of the container can be recovered via volume replication. This provides container volume replication for long-running containerized applications whose states keep changing.

In-memory database-managed container volume replication

Various examples are directed to systems and methods for operating a database management system (DBMS) in a cloud environment. An assembly worker executing at a first computing device may provide a first database protocol message generated by a process code executing at the first computing device. A translation engine executed at the cloud environment may translate the first database protocol message from a first format to a second format associated with a DBMS instance executing at the cloud environment to generate a translated first database protocol message. The translation engine may cause the translated first database protocol message to be provided to the DBMS instance and may receive, from the DBMS instance, a first reply corresponding to the translated first database protocol message. The first reply may be sent to the process code.

Cloud migration for legacy on-premises process code

In an example embodiment, a solution is used to provide for multiple and concurrent web application accessing of a database in a database-as-a-service (DBaaS) framework. More particularly, a cloud solution is provided on a DBaaS for leveraging Docker network functionality to provide a virtual Internet Protocol (IP) address pool, while utilizing in-memory database technology to set up an entire accessing solution for multiple and concurrent DBaaS users and web applications, which serve the data-intensive jobs to the in-memory database. This allows for improved functionality, performance, concurrency, and handling of network stress.

Elastic in-memory database provisioning on database-as-a-service

In an example embodiment, a solution is used to provide for a highly efficient image dispatch system for container-based in-memory databases in a database-as-a-service framework that provides storage and bandwidth cost savings and introduces advanced features of container techniques. This solution makes best use of the advantages of the concurrent and distributed capabilities of in-memory databases in a database-as-a-service framework. A container operator manager provides operators for various uses, such as the 'diff' operator and the 'merge' operator. A dispatch manager acts as a centralized service for diff content maintenance, patch publication and management of dispatch worker nodes. A patch worker on each node has the capabilities to execute the specified patching and validation between the images located on each side of the in-memory database in the database-as-a-service framework.

Peer-to-peer delta image dispatch system

In an example embodiment, a new solution is provided for an in-memory database provided in a cloud as a service that enables 'job cross running' instead of 'parallel job running.' Specifically, job scripts are clustered based on a shared service. A primary job script in the cluster is compiled and executed, but secondary job scripts in the cluster are not compiled until after the execution of the primary job script has begun. A mock library is inserted into each of the secondary job scripts to cause service calls for the shared service in the secondary job scripts to be replaced with mock service calls. The secondary job scripts are then scheduled and executed, and upon completion the primary job script is permitted to delete the shared service.
