Climate change is expected to aggravate wildfire activity through the exacerbation of fire weather. Improving our capabilities to anticipate wildfires on a global scale is of uttermost importance for mitigating their negative effects. In this work, we create a global fire dataset and demonstrate a prototype for predicting the presence of global burned areas on a sub-seasonal scale with the use of segmentation deep learning models. Particularly, we present an open-access global analysis-ready datacube, which contains a variety of variables related to the seasonal and sub-seasonal fire drivers (climate, vegetation, oceanic indices, human-related variables), as well as the historical burned areas and wildfire emissions for 2001-2021. We train a deep learning model, which treats global wildfire forecasting as an image segmentation task and skillfully predicts the presence of burned areas 8, 16, 32 and 64 days ahead of time. Our work motivates the use of deep learning for global burned area forecasting and paves the way towards improved anticipation of global wildfire patterns.

The cyber-physical convergence is opening up new business opportunities for industrial operators. The need for deep integration of the cyber and the physical worlds establishes a rich business agenda towards consolidating new system and network engineering approaches. This revolution would not be possible without the rich and heterogeneous sources of data, as well as the ability of their intelligent exploitation, mainly due to the fact that data will serve as a fundamental resource to promote Industry 4.0. One of the most fruitful research and practice areas emerging from this data-rich, cyber-physical, smart factory environment is the data-driven process monitoring field, which applies machine learning methodologies to enable predictive maintenance applications. In this paper, we examine popular time series forecasting techniques as well as supervised machine learning algorithms in the applied context of Industry 4.0, by transforming and preprocessing the historical industrial dataset of a packing machine's operational state recordings (real data coming from the production line of a manufacturing plant from the food and beverage domain). In our methodology, we use only a single signal concerning the machine's operational status to make our predictions, without considering other operational variables or fault and warning signals, hence its characterization as ``agnostic''. In this respect, the results demonstrate that the adopted methods achieve a quite promising performance on three targeted use cases.

如今,越来越多的数据集已发布针对系统和模型的研究和开发,从而直接比较,解决方案的持续改进以及研究人员参与实验,现实生活数据。但是,尤其是在结构健康监测(SHM)领域中,在许多情况下,新的研究项目具有结构设计和实施,传感器选择和技术推动因素的独特组合,这些组合不符合相关个人研究的配置文学。因此,由于我们没有找到任何相关存储库,因此我们将案例研究中的数据分享到研究界。更具体地说,在本文中,我们提出了一个新颖的时间序列数据集,用于使用陶瓷压电传感器(PZTS)连接到物联网(IOT)设备(IOT)设备的陶瓷压电传感器(PZTS),用于塑料薄板上的撞击检测和本地化,朝着结构性健康监测应用。数据集是从低速,低能冲击事件的实验过程中收集的,该过程包括每个独特的实验至少3个重复,而输入测量值来自放置在板的角落的4个PZT传感器。对于每个重复和传感器,以100 kHz的采样率存储5000个值。该系统用钢球激发,释放的高度从10厘米到20厘米不等。该数据集可在GitHub(https://github.com/smart-objects/impact-events-dataset)中获得。

考虑以下模型,以研究对意见形成的对抗性影响。一套最初选择的专家形成了他们的二进制意见,同时受到反对者的影响,他们可能会说服他们一些虚假的谎言。网络中的所有其他参与者然后对其大多数邻近专家的意见。对手可以影响专家,使大多数网络相信虚假的方式吗?Alon等人。[1]召集认为,在这种情况下,迭代传播过程将始终有利于对手。这项工作为该猜想提供了一个反例。[1] N.Alon,M. Feldman,O. Lev,以及M. Tennenholtz。人群的智慧是多么强大?在第24届国际人工智能联席会议(IJCAI 2015年),2015年第2055-2061页的第24届国际联席会议。
