TS-stream: clustering time series on data streams
The current ability to produce massive amounts of data and the impossibility in storing it motivated the development of data stream mining strategies. Despite the proposal of many techniques, this research area still lacks ...
Influence of environmental features at multiple scales and spatial structure on stream fish communities in a tropical agricultural region
(Taylor & Francis Inc, 2017-01-01)
Land cover change for agricultural expansion exerts strong pressures on tropical streams. We examined the relative contributions of catchment land cover, local environmental features, and spatial patterns on stream fish ...
The effects of land use at different spatial scales on instream features in agricultural streams
The conversion of forests into agriculture has been identified as a key process for stream homogenization. However, the effects of this conversion can be scale-dependent. In this context, our aim was to identify the influence ...
Amazon deforestation alters small stream structure, nitrogen biogeochemistry and connectivity to larger rivers
Human activities that modify land cover can alter the structure and biogeochemistry of small streams but these effects are poorly known over large regions of the humid tropics where rates of forest clearing are high. We ...
Assessment of chromium contamination in the Monte Alegre stream: a case study
The aim of this work was to study the contamination by chromium in the sediments of the Monte Alegre stream and in the larvae of Odonata and the possible impact caused by them on the stream macroinvertebrates community. ...
’HALITE IND. DS’: fast and scalable subspace clustering for multidimensional data streams
(Society for Industrial and Applied Mathematics - SIAMMiami, 2016-05)
Given a data stream with many attributes and high frequency of events, how to cluster similar events? Can it be done in real time? For example, how to cluster decades of frequent measurements of tens of climatic attributes ...
