Need a Helping Hand...

I'm an undergraduate at University of Colombo School of Computing, Sri Lanka. I'm doing a research on "Semantic web prefetching". In order to do a literature survey I want some related papers to review.

"Towards Semantics-Based Prefetching to Reduce Web Access Latency" by Cheng-Zhong Xu, Tamer I. Ibrahim

Above are two papers that I found out but since I have no logins in Springer, ACM or IEEE. Therefore I need someone's help to get those papers.

If someone has those papers and some other related papers please be kind enough to send them to me.

I guarantee that those papers are only for academic usage and not for sale or will not misuse them.

Thank You.

The World’s First OLTP Database Machine With FlashFire Technology

Based on a combination of Oracle software and innovative Sun hardware, including Sun's breakthrough FlashFire technology, Oracle Exadata V2 is built on a massively parallel architecture that brings together fast servers, and high-bandwidth interconnects between storage and database servers — a design that radically accelerates database processing and delivers exceptional performance.

Available in a range of configurations, the new Oracle Exadata V2 combines compute, storage and networking technologies, and features Sun FlashFire Technology to turbocharge applications. This uniquely well-balanced CPU, I/O and memory system yields high throughput networking and performance, designed and tuned for Oracle technology.

The result is a quantum leap in performance over Oracle's previous generation Exadata machine, including a 20x increase in random I/O and a 5x I/O bandwidth speedup with FlashFire Technology, as well as a 2x speedup in compute and network performance capacity. In short, the Oracle Exadata V2 is the world's fastest machine for both data warehousing and online transaction processing.

High-Performance Hardware from Sun

  • Fast X86 CPUs processors
  • 600 GB SAS Disks run at 6 Gigabits/Sec
  • Fast DDR3 Memory
  • 72 Gigabytes RAM per Database Server
  • 40 Gigabits/second InfiniBand Switch
  • 100 TB Disk Capacity per Sun Oracle Database Machine
  • Sun FlashFire Technology for High Speed Transaction Processing

Latest Software from Oracle

  • The latest generation of innovation - Oracle Database 11g, Release 2
  • Hybrid columnar compression for 10 to 50 times greater data compression
  • Smart Scans on compressed data for even faster query execution
  • Storage Indexes to further reduce disk I/Os
  • Offloading of query processing to storage using Smart Scans
  • Includes Oracle Enterprise Linux

Old aunts used to come up to me at weddings, poking me in the ribs and cackling, telling me,
"You're next."
They stopped after I started doing the same thing to them at funerals.
