Current Tracking Adaptive Control of Brushless DC Motors
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Korelasi Penentuan Daya Dukung Tiang Cara Empirik (Cpt) Dengan Pile Driven Analysis (Pda) Di Kota Pekanbaru [PDF]
Axial bearing capacity of pile foundation can be estimated empirically from cone penetration test (CPT). Actual capacity of foundation can be obtained from static load test or pile driving analyzer (PDA).

Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
