Estimating page fetches for index scans with finite LRU buffers

Proceedings of the 1994 ACM SIGMOD international conference on Management of data, 1994
We describe an algorithm for estimating the number of page fetches for a partial or complete scan of a B-tree index. The algorithm obtains estimates for the number of page fetches for an index scan when given the number of tuples selected and the number of LRU buffers currently available.

Construction of Tree-Based Indexes for Level-Contiguous Buffering Support

2007
In multimedia databases, the spatial index structures based on trees (like R-tree, M-tree) have been proved to be efficient and scalable for low-dimensional data retrieval. However, if the data dimensionality is too high, the hierarchy of nested regions (represented by the tree nodes) becomes spatially indistinct.

Index scans using a finite LRU buffer: a validated I/O model

ACM Transactions on Database Systems, 1989
Indexes are commonly employed to retrieve a portion of a file or to retrieve its records in a particular order. An accurate performance model of indexes is essential to the design, analysis, and tuning of file management and database systems, and particularly to database query optimization.

STORM imaging buffer with refractive index matched to standard immersion oil

2023
Abstract Stochastic optical reconstruction microscopy (STORM) provides exceptional super-resolution imaging by sparsely blinking individual dye molecules in thiol-containing media. STORM is now well-established for imaging thin biological specimens, and recent technological advancements have expanded its use to thick tissues.

Relationship between children's body mass index and saliva buffering capacity

Australian Dental Journal, 2007
[Extract] Obesity has become an increasing problem in the paediatric population. An association between Body Mass Index (BMI) and saliva buffering capacity has had limited investigation. Previous studies have found that caries experience is correlated to obesity and also salivary buffering capacity.

Relative buffer-index values for root saps of some crop plants

The Journal of Agricultural Science, 1948
SUMMARY1. Some data are given for the relative buffer-index values of saps from underground parts of wheat, barley, oats, potatoes and turnips.2. The correlation of these values with limits of tolerances of soil-pHranges by the plants is discussed.3. Some possible practical applications for these data are indicated.

Indexation of international commodity prices through international buffer stock operations

Journal of Policy Modeling, 1979
Abstract The developing economies have been advocating the indexation of the prices for their primary commodity exports by tying such prices to other relevant international prices, such as the prices of imports to the less-developed countries. We have used econometric models to simulate a program of indexation of the prices of the ten UNCTAD core ...

Optimizing a Decoupled Front-End Architecture: The Indexed Fetch Target Buffer (iFTB)

2003
A decoupled front-end architecture relies on a separate fetch predictor that is critical in determining the fetch bandwidth. The Fetch Target Buffer (FTB) is a multilevel fetch predictor design. In this paper we propose and analyze a variation of the FTB, the indexed Fetch Target Buffer (iFTB), that uses an extra, very fast, index table to speedup its ...
