摘要
En 中文
Sensors deployed within water distribution systems collect consumption data that enable the application of data analysis techniques to extract essential information. Time series clustering has been traditionally applied for modeling end-user water consumption profiles to aid water management. However, its effectiveness is limited by the diversity and local nature of consumption patterns. In addition, existing techniques cannot adequately handle changes in household composition, disruptive events (e.g., vacations), and consumption dynamics at different time scales. In this context, biclustering approaches provide a natural alternative to detect groups of end-users with coherent consumption profiles during local time periods while addressing the aforementioned limitations. This work discusses when, why and how to apply biclustering techniques for water consumption data analysis, and further proposes a methodology to this end. To the best of our knowledge, this is the first work introducing biclustering to water consumption data analysis. Results on data from a real-world water distribution system-Quinta do Lago, Portugal-confirm the potentialities of the proposed approach for pattern discovery with guarantees of statistical significance and robustness that entities can rely on for strategic planning.

An extraordinary and surprising agitation of the waters, though without any perceptible motion of the Earth, having been observed in various parts of this Island, both maritime and inland, on the same day, and chiefly about the time, that the more violent commotions of both Earth and waters so extensively affected many very distant parts of the Globe; the following accounts, relating to the former, have been transmitted to the Society; in which are specified the times and places when and where they hLVIII. 已观察到，在本岛（Island）的沿海及内陆各地区，同一天出现了异常且令人惊讶的水体骚动，尽管并未观测到地球的任何可察觉运动；这种情况主要发生在地球和水体发生剧烈动荡并广泛影响全球许多遥远地区的同时。关于前者的以下报告已提交至学会；其中具体说明了事件发生的时间和地点。
