System and method of search indexes using key-value attributes to searchable metadata
Systems, methods, and computer program products for searching objects, metadata associated with the objects, and attributes assigned to or associated with the metadata. Referring to herein as metadata for the metadata, these attributes may be associated with one or more metadata field values of a metadata field name which, in turn, may be associated with an object being or already indexed in a search index of a search system. Each attribute may be optional, dynamically created, indexed, and searchable via the search index. There can be multiple attributes associated with the same metadata field value, each being represented as a key-value pair. This metadata for the metadata approach can be highly efficient. For example, the ability to search multiple attributes associated with the same metadata field can eliminate the potential need to create multiple metadata fields for the same value in different languages, countries, etc. |

System and method for column-specific materialization scheduling
A method of dynamically computing an optimal materialization schedule for each column in a column oriented RDBMS. Dynamic column-specific materialization scheduling in a distributed column oriented RDBMS is optimized by choosing a materialization strategy based on execution cost including central processing unit (CPU), disk, and network costs for each individual exchange operator. The dynamic programming approach is computationally feasible because the optimal schedule for a sub-plan is path independent. |

Petri net-based optimal one-wafer cyclic scheduling of treelike hybrid multi-cluster tools
Since single and dual-arm tools behave differently, it is difficult to coordinate their activities in a hybrid multi-cluster tool that is composed of both single- and dual-arm tools. Aiming at finding an optimal one-wafer cyclic schedule for a treelike hybrid multi-cluster tool whose bottleneck tool is process-bound, the present work extends a resource-oriented Petri net to model such system. By the developed Petri net model, to find a one-wafer cyclic schedule is to determine robot waiting times. By doing so, it is shown that, for any treelike hybrid multi-cluster tool whose bottleneck tool is process-bound, there is always a one-wafer cyclic schedule. Then, computationally efficient algorithms are developed to obtain the minimal cycle time and the optimal one-wafer cyclic schedule. Examples are given to illustrate the developed method. |
