When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

This chapter extends the Fourier series representation of discrete time periodic functions to aperiodic functions. We investigate the power of the discrete time Fourier transform in manipulating the ...

Blockchain analytics company Chainalysis has rolled out a new automation feature aimed at broadening access to onchain investigative and compliance tools beyond technical users. The feature, called ...

Abstract: The short-time Fourier transform (STFT) is widely used for analyzing non-stationary signals. However, its performance is highly sensitive to its parameters, and manual or heuristic tuning ...

This project is a demonstration of a complete ETL (Extract, Transform, Load) pipeline built with Python. It simulates a real-world data engineering task: integrating a healthcare provider's Electronic ...

Este projeto demonstra como construir um pipeline de dados completo que extrai informações de criptomoedas, processa e armazena em formato otimizado, simulando a arquitetura de um Data Lake na AWS.
