Data measurements

In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

Ontology matching, a field within data management and information retrieval, utilizes machine learning to integrate and link different data sources by identifying equivalences and relationships between concepts across various ontologies. This report provides an overview of key techniques and methods in ontology matching, including vectorization and embeddings such as Word2Vec, similarity measure like Levenshtein Distance and Jaccard Index, and machine learning models that improve accuracy in classifying and matching concepts.

The paper conducts an empirical investigation to examine whether there is a linkage between financial development and income disparity or not. Final results withdrawn from the ARDL model, which is employed to deal with Vietnam’s national-level time series data from 1992 to 2021, reveal that the influence of financial development on income inequality depends on the specific measure used to capture its multidimensional aspects.
