Optimization of the electrocoagulation process using aluminum electrodes for effective treatment of household wastewater: A kinetic and economic analysis of time and electrode distance effects

This study demonstrates that optimizing batch electrocoagulation with aluminum electrodes by minimizing inter-electrode spacing to 0.2 cm and operating for 90 minutes achieves over 96% removal of household wastewater contaminants with pseudo-first-order kinetics, despite resulting in an operating cost of $4.37 per cubic meter.

Error-Envelope-Optimal G2 Dual Bezier Corner Transitions for High-Speed Five-Axis CNC  Toolpaths

This paper proposes a local corner-smoothing method for high-speed five-axis CNC machining that utilizes parameter-synchronized dual quartic Bezier segments to achieve G2 continuity within a defined error envelope, while incorporating a lightweight rotary-axis stabilization strategy to suppress curvature peaks and enhance feedrate stability without explicit Jacobian evaluation.
