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

A Result on Output Feedback Linear Quadratic Control [PDF]
In this note we consider the static output feedback linear quadratic control problem.We present both necessary and sufficient conditions under which this problem has a solution in case the involved cost depend only on the output and control variables ...

Potential Output and the Output Gap in Ireland [PDF]
The performance of the Irish economy in recent years has been outstanding. Between 1994 and 2000, Ireland’s economic growth, as measured by the annual percentage change in real GDP (Gross Domestic Product), has expanded at an annual average rate of ...

This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight
