摘要： Systems, methods, and non-transitory computer readable media including instructions for a dual-channel fluid turbine controller. A dual-channel fluid turbine controller includes at least one processor configured to: receive, via an AC channel coupled to an AC output of a fluid turbine, first signals indicating fluctuations in power generated by the fluid turbine operating beneath a grid power supply threshold; access an MPPT protocol; determine a correspondence between the first signals and a portion of the MPPT protocol; apply the portion of the MPPT protocol to a generator of the fluid turbine to generate greater power than would be generated in an absence of the MPPT protocol, wherein the generated power is stored as energy in a capacitor associated with the generator; receive, via a DC channel, second signals indicating a level of energy stored in the capacitor; and use the second signals to determine when to release the stored energy.

摘要： Systems, methods, and non-transitory computer readable media including instructions for an aggregated voltage controller for a cluster of fluid turbines. An aggregated voltage controller includes at least one processor configured to: receive a target voltage for the cluster; receive via a plurality of rectifiers, each associated with a different turbine, an indication of a DC voltage associated with each turbine, wherein the DC voltage associated with at least one of the turbines is below the target voltage; and based on the received indications of the DC voltage signals associated with each turbine in the cluster, output a control signal to each of a plurality of DC-DC converters associated with the plurality of rectifiers, each control signal configured to regulate each DC-DC converter to produce a DC output at the target voltage such that combining each DC output in parallel produces an aggregated DC voltage conforming to the target voltage.

摘要： Embodiments of the present invention relate to systems, methods, and computer-storage media for affinitizing datasets based on efficient query processing. In one embodiment, a plurality of datasets within a data stream is received. The data stream is partitioned based on efficient query processing. Once the data stream is partitioned, an affinity identifier is assigned to datasets based on the partitioning of the dataset. Further, when datasets are broken into extents, the affinity identifier of the parent dataset is retained in the resulting extent. The affinity identifier of each extent is then referenced to preferentially store extents having common affinity identifiers within close proximity of one other across a data center.

摘要： A method of providing data files includes compressing the files using a cross-file compression technique. The technique makes use of ancillary files that are stored along with the data files. The ancillary files include lookup tables and indexes. A lookup table for a data file indicates the position of the last occurrence of individual data values within the data file. Each displacement index for a data file indicates displacements from respective data elements to prior strings of a particular match length that match strings of the particular match length begun by the respective data elements. Indexes corresponding to different match lengths are provided. In response to client requests for subsets of available data files, a server compresses each subset of data files using a pattern-matching compression scheme that attempts to represent given strings by referencing prior matching strings across file boundaries. To find a prior matching string for a string begun by a current data element in a current data file, the server finds a previous matching string in the current data file by referencing the displacement indexes associated with the current data file, and then searches for a larger matching string in previous data files by referencing the lookup tables and displacement indexes associated with the previous data files.

摘要翻译： 提供数据文件的方法包括使用跨文件压缩技术压缩文件。 该技术利用与数据文件一起存储的辅助文件。 辅助文件包括查找表和索引。 数据文件的查找表指示数据文件中单个数据值的最后一次出现的位置。 数据文件的每个位移指数指示从相应数据元素到匹配由相应数据元素开始的特定匹配长度的字符串的特定匹配长度的先前字符串的位移。 提供了与不同匹配长度对应的索引。 响应于客户端对可用数据文件子集的请求，服务器使用模式匹配压缩方案来压缩数据文件的每个子集，该模式匹配压缩方案通过引用跨文件边界的先前匹配字符串来尝试表示给定的字符串。 要查找当前数据文件中由当前数据元素开始的字符串的先前匹配字符串，服务器将通过引用与当前数据文件相关联的位移索引来查找当前数据文件中的先前匹配字符串，然后搜索 通过引用与先前数据文件相关联的查找表和位移指数，可以获得先前数据文件中较大的匹配字符串。
