An Improvement in Temporal Resolution of Seismic Data Using Logarithmic Time-frequency Transform Method
The improvement in the temporal resolution of seismic data is a critical issue in hydrocarbon exploration. It is important for obtaining more detailed structural and stratigraphic information. Many methods have been introduced to improve the vertical resolution of reflection seismic data. Each method has advantages and disadvantages which are due to the assumptions and theories governing their ...

An Index Data Structure for Searching in Metric Space Databases
This paper presents the Evolutionary Geometric Near-neighbor Access Tree (EGNAT) which is a new data structure devised for searching in metric space databases. The EGNAT is fully dynamic, i.e., it allows combinations of insert and delete operations, and has been optimized for secondary memory. Empirical results on different databases show that this tree achieves good performance for high-dimens...
متن کاملAn Implicit Data Structure for the Dictionary Problem that Runs in Polylog Time
We introduce a data structure that requires only one pointer for every k data values and permits the operations search, insert and delete to be performed in 0 (k log n ) time. This structure is used to develop another that requires no pointers and supports insert, delete and search in 0 (log2 n ) time. 1. The Problem and the Results Pointers are routinely used to indicate relationship between k...
