A unified heuristic and an annotated bibliography for a large class of earliness-tardiness scheduling problems

open access: yes, 2017
This work proposes a unified heuristic algorithm for a large class of earliness-tardiness (E-T) scheduling problems. We consider single/parallel machine E-T problems that may or may not consider some additional features such as idle time, setup times and

NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]

open access: yes, 2010
The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...

Multifunctional Structural Electrolyte with Glass Fiber‐Reinforced Polyvinyl Alcohol/Epoxy Matrix with Optimized Lithium Salt and Nanofiller

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study presents a novel structural electrolyte reinforced with glass fiber and a polyvinyl alcohol/epoxy matrix incorporating optimized lithium salt and ceramic nanofiller. Its multifunctionality—mechanical, electrochemical, and thermomechanical—is evaluated using various characterization techniques.
