    • Technologies are generally provided for maintaining performance level of a database being migrated between different cloud-based service providers employing machine learning. In some examples, data requests submitted to an original data store/database may be submitted to a machine learning-based filter for recording and analysis. Based on the results of the data requests and the filter analyses, new key value structures for a new data store/database may be created. The filter may assign performance scores to the original data requests (made to the original data store) and data requests made to the newly-created key value structures. The filter may then compare the performance scores associated with the created key value structures to each other and to performance scores associated with the original data requests and may select the created key value structures with performance scores that are at least substantially equal to those of the original data requests for the new data store.
    • 通常提供技术来保持使用机器学习的不同的基于云的服务提供商之间迁移的数据库的性能水平。 在一些示例中,提交给原始数据存储/数据库的数据请求可以被提交到基于机器学习的过滤器用于记录和分析。 基于数据请求和过滤器分析的结果,可以创建新的数据存储/数据库的新的键值结构。 过滤器可以将原始数据请求(对原始数据存储区做出)的性能分数和对新创建的键值结构的数据请求分配。 然后,过滤器可以将与所创建的关键值结构相关联的绩效评分与彼此进行比较,以及与原始数据请求相关联的绩效评分,并且可以选择具有至少基本上等于原始数据请求的性能分数的所创建的关键值结构 新数据存储的数据请求。

    • A flow pattern transition pipe for use in a pneumatic conveyance system is provided. The flow pattern transition pipe comprises a first expansion pipe section gradually increasing in inner diameter in an axial direction, a second shrink pipe section following the first section from a maximum inner diameter end of the first section and gradually reducing in inner diameter in an axial direction away from the first section, and a third pipe section following the second section from a minimum inner diameter end of the second section, with a substantially identical inner diameter smaller than a minimum inner diameter of the first section. An axial length of the first section is from about three to about five times of the axial length of the second section.

    • A tunable optical demultiplexer includes a control circuit and one or more heaters thermally coupled to waveguides of an optical demux. The control circuit is in signal communication with the one or more heaters and includes a processor coupled to a memory. The control circuit is configured to receive an optical channel group (OCG) identification signal and adjust the power delivered to the heaters in response to the OCG identification signal and based on parameter values stored in the memory. The optical demux outputs a plurality of optical signals at a corresponding one of a plurality of outputs. The transmission characteristics of the optical demux are varied depending on the amount of power delivered to the heaters. The varying of the transmission characteristics of the optical demux adjusts the spectral shifting of the plurality of wavelengths output by the optical demux.
    • 可调谐光解复用器包括控制电路和热耦合到光学解复用器的波导的一个或多个加热器。 控制电路与一个或多个加热器信号通信,并且包括耦合到存储器的处理器。 控制电路被配置为接收光通道组(OCG)识别信号,并且响应于OCG识别信号并且基于存储在存储器中的参数值来调节传送到加热器的功率。 光解复用器在多个输出中相应的一个输出端输出多个光信号。 光学解复用器的传输特性根据传送到加热器的功率量而变化。 光学解复用器的传输特性的变化调节由光学解复用器输出的多个波长的光谱偏移。
