  • Publication number: 20100005077
    Abstract: Embodiments of the present invention generate and optimize query plans that are at least partially executable in hardware. Upon receiving a query, the query is rewritten and optimized with a bias for hardware execution of fragments of the query. A template-based algorithm may be employed for transforming a query into fragments and then into query tasks. The various query tasks can then be routed to either a hardware accelerator, a software module, or sent back to a database management system for execution. For those tasks routed to the hardware accelerator, the query tasks are compiled into machine code database instructions.

  • Publication number: 20100005468
    Abstract: Throughput of a high-volume throughput-centric computer system is controlled by dynamically adjusting a concurrency level of a plurality of events being processed in a computer system to meet a predetermined target for utilization of one or more resources of a computer system. The predetermined target is less than 100% utilization of said one or more resources. The adjusted concurrency level is validated using one or more queuing models to check that said predetermined target is being met. Parameters are configured for adjusting the concurrency level. The parameters are configured so that said one or more resources are shared with one or more external programs. A statistical algorithm is established that minimizes total number of samples collected. The samples may be used to measure performance used to further dynamically adjust the concurrency level.

  • Patent number: 7636735
    Abstract: Provided is a method for modeling the cost of XML as well as relational operators. As with traditional relational cost estimation, a set of system catalog statistics that summarizes the XML data is exploited; however, the novel use of a set of simple path statistics is also proposed. A new statistical learning technique called transform regression is utilized instead of detailed analytical models to predict the overall cost of an operator. Additionally, a query optimizer in a database is enabled to be self-tuning, automatically adapting to changes over time in the query workload and in the system environment.

  • Patent number: 7459121
    Abstract: Methods and devices are provided for the continuous production of a network of nanotubes or other nanoscale fibers. The method includes making a suspension of nanoscale fibers dispersed in a liquid medium, optionally with surfactant and/or sonication, and filtering the suspension by moving a filter membrane through the suspension, such that the nanoscale fibers are deposited directly on the filter membrane as the fluid medium flows through the filter membrane, thereby forming a continuous membrane of the nanoscale fibers. The deposition of the nanoscale fibers can occur when and where the filter membrane moves into contact with a static, porous filter element or a dynamic, porous filter element. The filtering can be conducted within a magnetic field effective to align the nanoscale fibers, and/or with the aid of vacuum to pull water through the filter membrane, applied pressure to press water though the filter membrane, or a combination thereof.

  • Publication number: 20080280115
    Abstract: A technique is provided for the fabrication of multi-walled carbon nanotube (MWNT) and carbon nanofiber (CNF) film materials. The method includes mixing a relatively small amount of single-walled nanotubes (SWNTs) with larger amounts of MWNTs and CNFs, which enables one to produce highly flexible SWNT materials—advantageously without the need for bonding agents and at significantly lower costs compared to flexible SWNT materials. The method exploits SWNTs tendency to entangle together to form flexible films, using a small amount of SWNTs to wrap around and entangle the larger diameter MWNTs and CNFs together to form flexible films with highly beneficial mechanical, electrical, and thermal properties at a fraction of the cost of SWNT materials.
