The health management of weather radar plays a key role in achieving timely and accurate weather forecasting. The current practice mainly exploits a fixed threshold prespecified for some monitoring parameters for fault detection. This causes abundant false alarms due to the evolving working environments, increasing complexity of the modern weather radar, and the ignorance of the dependencies among monitoring parameters. To address the above issues, we propose a deep learning-based health monitoring framework for weather radar. First, we develop a two-stage approach for problem formulation that address issues of fault scarcity and abundant false fault alarms in processing the databases of monitoring data, fault alarm record, and maintenance records. The temporal evolution of weather radar under healthy conditions is represented by a long short-term memory network (LSTM) model. As such, any anomaly can be identified according to the deviation between the LSTM-based prediction and the actual measurement. Then, construct a health indicator based on the portion of the occurrence of deviation beyond a user-specified threshold within a time window. The proposed framework is demonstrated by a real case study for the Chinese S-band weather radar (CINRAD-SA). The results validate the effectiveness of the proposed framework in providing early fault warnings.

The specificity of this article is the consideration not only of the completed text entitled A Duma about Brytanka, but also of the play-forming and creating process, which became possible due to the presence of drafts and draft notes to the work. Therefore, this study is conducted not only in along the lines of literary theory, but also textology. The relevance of the study is that the view from above allows us to comprehend, or even rethink, the play A Duma about Brytanka in the context of the author’s work and also in the context of the Soviet drama landscape in general. Understanding and rethinking the work of predecessors is an important process for comprehending the development of literature as a general process and its development within the national borders. The aim of the study at hand is to determine how the realities of the time and especially the accepted literary trend and historical events influenced the formation of the text of the play. The results of the study show that the original idea of A Duma about Brytanka had much more romantic features, as romanticism as a style of thinking was inherent for Yuri Yanovskyi. However, in the process of creating the play, the author began to rely on the documents that showed the real case of the social republic. The author abandoned the original version and completed the play so that it became much closer to the Soviet canon than to romanticism.

Renewable energy has a crucial role in facing climate change. One promising strategy is the creation of energy communities that require active involvement from a bottom-up perspective. Their implementation is difficult, as they currently rely on local policies, community readiness, and technological availability. The objective of this paper is to provide a qualitative overview of energy community concepts and strategies at the European level. The aim is to identify common approaches that are framing the development of energy communities, and to understand the most successful steps leading to their creation and growth. To achieve this objective, a threefold methodology is provided: (1) an updated review on policies dealing with energy communities at the European and Italian level; (2) a qualitative overview of European-funded projects under the Horizon 2020 work program; and (3) a qualitative overview of some of the most successful existing energy communities in Europe. The results outline a series of considerations and lessons learned that are useful for implementing this transition pathway in a real case, which is also presented in the paper. The conclusions will identify some future directions of this research, particularly in relation to the results coming from the implementation of actions in the real case.
