Abstract: A line search was combined with the Newton-Raphson method to accelerate the convergence of the iterative calculation in nonlinear magnetic field analysis. As a method for determining a step ...

Abstract: In machine learning and statistics, the penalized regression methods are the main tools for variable selection (or feature selection) in high-dimensional sparse data analysis. Due to the ...

Ultra-wideband (UWB) antennas play a vital role in modern communication, sensing, and imaging systems owing to their ability to operate over a broad frequency range while supporting high data rates ...

Game developers didn’t have it easy in the 1990s. Because they had extremely limited computing power, they had to write their code as efficiently as possible. Consider the first-person shooter Quake ...

We’re suckers for good-looking old-school calculators, so this interesting numerical equation-solving calculator by [Peter Balch] caught our attention. Based around the ESP32-WROOM-32 module and an ...

Introduction: In dynamic PET analysis, the time-activity curves (TACs) observed in each tissue exhibit delays that deviate from the expected arterial input. Particularly in the context of Total-body ...

A basic Newton-Raphson type nonlinear equation solver for sparse or dense systems with m functions of n input variables. Is object-oriented. Works with square, under-determined, or over-determined ...

Py_PSOPS is the Python API for PSOPS. PSOPS stands for Power System Optimal Parameter Selection. It is a cpp-writen power system electromechanical simulator. Currently, It can solve power flow with ...
