I currently work as an IT engineer, and since I want to further sharpen my coding and algorithm skills, I am outputting what I have learned on LeetCode as notes. The problem I solved this time is "39.

Abstract: In this paper, we propose a novel 2D hyperchaotic Sine couple map (2D-HSCM) and then the proposed 2D map is analyzed using bifurcation diagrams, attractor trajectory, Lyapunov exponent, ...

As a kind of clean and renewable energy, wind power is of great significance for alleviating energy crisis and environmental pollution. However, the strong randomness and large volatility of wind ...

The world is rich in heavy oil resources, however, the recovery difficulty and cost are both higher than that of conventional crude oil. To date, the most common method of recovering heavy oil is ...

Maxwell (1864) predicted that 3D networks of beams fixed to junctions through freely rotating joints will be rigid only if at least six beams emanate from each junction. This concept is key to ...

Abstract: The silicon physical unclonable functions (PUF) measure uncontrollable variations of the integrated circuit (IC) fabrication process to facilitate IC authentication. One of the most reliable ...
