Many realworld optimization problems are dynamic optimization problems (DOPs), where changes may occur over time regarding the objective function, decision variable, and constraints, etc. DOPs raise big challenges to traditional optimization methods as well as evolutionary algorithms (EAs). The last decade has witnessed increasing research efforts on handling dynamic optimization problems using...

Discrete optimization problems (DOPs) arise in various applications such as planning, scheduling , computer aided design, robotics, game playing and constraint directed reasoning. Often, a DOP is formulated in terms of nding a (minimum cost) solution path in a graph from an initial node to a goal node and solved by graph/tree search methods. Availability of parallel computers has created substa...

BACKGROUND GI endoscopy simulation-based training augments early clinical performance; however, the optimal manner by which to deliver training is unknown. OBJECTIVE We aimed to validate a simulation-based structured comprehensive curriculum (SCC) designed to teach technical, cognitive, and integrative competencies in colonoscopy. DESIGN Single-blinded, randomized, controlled trial. SETTI...

Background: Simulation teaching means recreating clinical scenario for training / evaluation. Aim: To expose postgraduates to simulation / didactic lecture for postpartum hemorrhage (PPH) management; to assess which method was more effective. Methods: Present prospective study was conducted in Obstetrics Gynecology department of rural tertiary center of Northern India.  Twenty postgraduates wer...

Polarization underwater imaging is of great potential to target detection in turbid water. Typical methods are challenged by the requirement on degrees polarization (DoPs) both light and backscattering. A descattering method was developed using Mueller matrix, which turn derived a depolarization (Dep) index from matrix characterize scattering media estimating transmittance map combining optimal...

Este artigo propõe analisar a trajetória dos padres operários da congregação Filhos Caridade, sacerdotes de maioria francesa que atuaram na diocese Santos/SP durante o período ditadura militar. Responsáveis pela rearticulação Juventude Operária Católica (JOC) região Baixada Santista, lidaram com intensa vigilância, sendo três deles presos data promulgação do AI-5. Utilizamos como principal refe...
