Revised clusters of annotated unknown sounds in the Belgian part of the North sea

open access: yesFrontiers in Remote Sensing
Acoustic signals, especially those of biological source, remain unexplored in the Belgian part of the North Sea (BPNS). The BPNS, although dominated by anthrophony (sounds from human activities), is expected to be acoustically diverse given the presence ...

Search on a Grid: Directed Consumer Search With Correlated Products

open access: yesSSRN Electronic Journal
The consumer search literature mostly considers independently distributed products. In contrast, I study a model of directed search with infinitely many products whose valuations are correlated through shared attributes. I propose a tractable, systematic, history-dependent scoring system based on nests of correlated products that leverages the ...

Analysis of noise immunity of a neural network system for recognizing subsurface objects

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка
Background: Subsurface sensing systems based on impulse electromagnetic waves are widely used for detecting hidden objects in soil. However, the performance of such systems significantly degrades in the presence of strong interference caused by external ...

Comparison tomography relocation hypocenter grid search and guided grid search method in Java island

open access: yesJournal of Physics: Conference Series, 2016
The main data in this research is earthquake data recorded from 1952 to 2012 with 9162 P wave and 2426 events are recorded by 30 stations located around Java island. Relocation hypocenter processed using grid search and guidded grid search method. Then the result of relocation hypocenter become input for tomography pseudo bending inversion process.

Optimizing SVM for argan tree classification using Sentinel-2 data: A case study in the Sous-Massa Region, Morocco

open access: yesRevista de Teledetección
The development of efficient classifiers for land cover remains challenging due to the presence of hyperparameters in the model. Conventional approaches rely on manual tuning, which is both time-consuming and impractical, often leading to suboptimal ...

Efficient data structures for range searching on a grid [PDF]

open access: yesJournal of Algorithms, 1988
We consider the 2-dimensional range searching problem in the case where all points lie on an integer grid. A new data structure is presented that solves range queries on a U*U grid in \(O(k+\log \log U)\) time using O(n log n) storage, where n is the number of points and k the number of reported answers.
