Disruptions are a major operational concern for next generation tokamaks, including ITER.They may generate excessive heat loads on plasma facing components, large electromagnetic forces in the machine structures and several MA of multi-MeV runaway electrons.A more complete understanding processes methods to suppress them is necessary ensure safe reliable operation future tokamaks.Runaway electrons were studied at JET-ILW showing that their dependencies (accelerating electric field, avalanche...
A recuperação pós-acidente vascular cerebral (AVC) hemorrágico é um desafio clínico significativo, com a terapêutica atual buscando restabelecer funções motoras e cognitivas prejudicadas. As abordagens terapêuticas incluem tratamentos farmacológicos de reabilitação, sendo fisioterapia as terapias baseadas em robôs promissoras para motora. O tPA, embora aprovado pelo FDA, tem limitações quanto à janela aos pacientes elegíveis. Terapias farmacológicas alternativas, como agonistas do receptor...
A retinopatia diabética é uma das principais causas de cegueira no mundo, mas, quando detectada precocemente, tratável e, muitas vezes, prevenível. atenção primária à saúde (APS) desempenha um papel crucial na detecção precoce desta complicação, pois o primeiro nível cuidado ao qual os pacientes têm acesso. O objetivo deste estudo analisar as estratégias para da e prevenção APS. foi realizado através busca nas bases dados Medline/PubMed Scientific Electronic Library Online (Scielo). questão...
Devido aos avanços no diagnóstico precoce e tratamento do câncer (CA), a sobrevida desses pacientes têm aumentado. No entanto, muitos sobreviventes enfrentam desafios psicológicos significativos que podem impactar na qualidade de vida. Por esse motivo, presente pesquisa contribui para ampliar compreender o impacto psicológico CA, explorando como as experiências sobrevivência gerar transtornos ansiedade depressão. Além disso, objetiva oferecer intervenções psicoterapêuticas identificar os...
Uma distribuição mais justa da educação pode ser um meio de reduzir a desigualdade socioeconômica. Assim, o objetivo do artigo foi desenvolver índices educacional para os primeiros anos básica no Brasil, referentes ao período 2015-2021. Foi utilizado material Sistema Avaliação Educação Básica (SAEB). Os Gini e Theil foram utilizados como metodologia. resultados mostraram que aumentou durante observação, fortemente pandemia COVID-19. As regiões desiguais Nordeste Norte. Além disso,...
The new JET ITER-like wall (made of beryllium and tungsten) is more fragile than the former carbon fiber composite requires active protection to prevent excessive heat loads on plasma facing components (PFC). Analog CCD cameras operating in near infrared wavelength are used measure surface temperature PFCs. Region interest (ROI) analysis performed real time maximum measured each ROI sent vessel thermal map. system started October 2011 has already successfully led a safe landing when hot...
Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat particle loads on wall is a major challenge. The new European medium size tokamak task force (EU-MST) coordinates research ASDEX Upgrade (AUG), MAST TCV. This multi-machine approach within EU-MST, covering wide parameter range, instrumental progress in field, as ITER DEMO core/pedestal SOL parameters are not achievable simultaneously present day devices. A two prong adopted. On one...
The Multithreaded Application Real-Time executor (MARTe) is a data driven framework environment for the development and deployment of real-time control algorithms. main ideas which led to present version were standardize systems, while providing set strictly bounded standard interfaces outside world also accommodating collection facilities promote speed ease development, commissioning such systems. At core every MARTe based application, independent inter-communicating software blocks, named...
The recent development of real-time measurements and control tools in JET has enhanced the reliability reproducibility relevant ITER scenarios.

The installation of international thermonuclear experimental reactor-relevant materials for the plasma facing components (PFCs) in Joint European Torus (JET) is expected to have a strong impact on operation and protection experiment. In particular, use all-beryllium tiles, which deteriorate at substantially lower temperature than formerly installed carbon fiber composite imposes strict thermal restrictions PFCs during operation. Prompt precise responses are therefore required whenever...
Real-time harmonic estimation and frequency tracking are well known pivotal problems in many engineering domains. Incidentally, similar challenges arise tokamak plasma diagnostics' data processing where the spectral complexity of characteristic signals poses additional obstacles. Building up on previous Kalman filter based developments, this paper describes an adaptive real-time algorithm for simultaneous multi-component noisy signals. Furthermore, proposed gain adaptation method is shown to...
Abstract The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, profile or synchrotron frequency distribution. However, collective effects, in particular beam-coupling impedance, significantly affect spectra when large charges are involved. In conditions, available interpretation methods difficult apply directly measured spectra, thus preventing extraction and machine...

Moreover, it designed overcome former data acquisition (DAQ)...
The ITER control, data access and communication (CODAC) design team identified the need for two types of plant systems. A slow control system is based on industrial automation technology with maximum sampling rates below 100 Hz, a fast embedded higher more stringent real-time requirements than that required controllers. latter applicable to diagnostics systems in closed-control loops whose cycle times are 1 ms. Fast controllers will be dedicated ability supervise other and/or controllers,...
