Abstract
While the desire to support fast, ad hoc query processing for large data warehouses has motivated the recent introduction of many new indexing structures, with a few notable exceptions little attention has been given to developing new indexing schemes that allow fast insertions. Since additions to a large warehouse may number in the millions per day, indices that require a disk seek (or even a significant fractio ....etc

Abstract
Detection of double joint photographic experts group (JPEG) compression is of great significance in the field of digital forensics. Some successful approaches have been presented for detecting double JPEG compression when the primary compression and the secondary compression have different quantization matrixes. However, when the primary compression and the secondary compression have the same quantization matrix, no detection method has been reported yet. In this paper, we present a method which can detect double JPEG compress ....etc

A 130nm CMOS to Minimize area and quantization noise in frequency synthesizer using offset PLL
ABSTRACT
 It achieves low-noise .
 OPLL highly suppresses the quantization noise from the delta-sigma modulator.
 It consumes low power by employing charge-recycling
technique in the sub-PLL.
 Synthesizer implemented in 0.13 ȗm
 CMOS process achieves 9 dB of noise reduction compared to a conventional PLL while consuming 3.2 mW of po ....etc

Quantization


This involves representing the sampled data by a finite number of levels based on some criteria such as minimization of the quantizer distortion, which must be meaningful.

Quantizer design includes input (decision) levels and output (reconstruction) levels as well as number of levels. The decision can be enhanced by psychovisual or psychoacoustic perception.

Quantizers can be classified as memoryless (assumes each sample is quantized independently ....etc

Hi,
I am Jayasree.N ; M.Tech student from Osmania University. Iam working on a Project: Optimal location of FACTS devices for improvemnt of Voltage Stability ; In this regard, could any one please mail me the MATLAB code for L index?

I have done loadflow for 30 bus system in NR method; got the Y bus matrix for IEEE 30 bus system. Now how to separate the load and generator buses -- some one please let me know.
Thank You

ONLINE INDEX RECOMMENDATIONS FOR HIGH-DIMENSIONAL DATABASES USING QUERY WORKLOADS

Abstract: Usually users are interested in querying data over a relatively small subset of the entire attribute set at a time. A potential solution is to use lower dimensional indexes that accurately represent the user access patterns. If the query pattern change, then the query response using the physical database design that is developed based on a static snapshot of the query workload may significantly degrade To address these issues, we introduce a parameter ....etc
