TransientBVD 1.0.0 – Initial stable release

TransientBVD v1.0.0

This is the first stable release of TransientBVD, a Python library for analyzing and optimizing the transient response of ultrasonic transducers and other resonant systems using the Butterworth–Van Dyke (BVD) equivalent circuit.

Highlights

• Transient-response analysis based on the BVD model
• Activation optimization via voltage overboost
• Deactivation optimization via resistive damping
• Documentation with usage guides, API reference, and examples
• Citation information updated to the published paper
