In the planar perovskite solar cells (PSCs), the electron transport layer (ETL) plays a critical role in electron extraction and transport. Widely utilized TiO2 ETLs suffer from the low conductivity and high surface defect density. To address these problems, for the first time, two types of ETLs based on TiO2 phase junction are designed and fabricated distributed in the opposite space, namely a...

Taking the hospital performance appraisal items as the background, the method and mechanism of ETL process, data extraction, data cleaning, data transformation and increment updating are concretely analyzed and designed in the article. The data preparation area is added in the ETL process of the system, and the monitoring and restarting mechanism is set up in the system, which can effectively e...

This paper surveys the interface between the two major logical trends that describe agents’ intelligent interaction over time: dynamic epistemic logic (DEL) and epistemic temporal logic (ETL). The initial attempt to “merge” DEL and ETL was made in [12] and followed up by [11] and [29]. The merged framework provides a systematic comparison between these two logical systems and studies new logics...

Business Intelligence (BI) enables organizations to collect and analyze internal and external business data to generate knowledge and business value, and provide decision support at the strategic, tactical, and operational levels. The consolidation of data coming from many sources as a result of managerial and operational business processes, usually referred to as ExtractTransform-Load (ETL) is...

We present UnifiedViews, an Extract-Transform-Load (ETL) framework that allows users to define, execute, monitor, debug, schedule, and share ETL data processing tasks, which may employ custom plugins created by users. UnifiedViews differs from other ETL frameworks by natively supporting RDF data and ontologies. We are persuaded that UnifiedViews helps RDF/Linked Data consumers to address the pr...

The back-end tools of a data warehouse are pieces of software responsible for the extraction of data from several sources, their cleansing, customization, and insertion into a data warehouse. They are known under the general term extraction, transformation and loading (ETL) tools. In all the phases of an ETL process (extraction and exportation, transformation and cleaning, and loading), individ...

In normal humans during quiet breathing, expiration is mostly driven by elastic recoil of the lungs. Expiration becomes active when ventilation must be increased to meet augmented metabolic demands, or in response to expiratory loading, be it experimental or disease-related. The response to expiratory loading is considered to be mediated by both reflex and cortical mechanisms, but the latter ph...

The proliferation of business intelligence applications moves most organizations into an era where data becomes an essential part of the success factors. More and more business focus has thus been added to the integration and processing of data in the enterprise environment. Developing and maintaining Extraction-Transform-Load (ETL) processes becomes critical in most data-driven organizations. ...
