Highlights
  • Interactive FID and spectra simulations
  • Adjustable peak positions and decay
  • Noise and apodization control
  • Zero filling and phase correction
  • Simulate acquisition artifacts
  • Explore spin-spin coupling

NMR Tutor is an interactive introduction to NMR data acquisition and signal processing. Use simulated free induction decays (FIDs) and spectra to explore how time-domain NMR signals become frequency-domain spectra. Adjust peak positions, decay, noise, apodization, zero filling, phase behavior, and common acquisition artifacts, then see the effect immediately in the FID and final spectrum. The app displays real and imaginary FID channels before and after processing, together with the resulting spectrum after Fourier transformation. A live signal-to-noise (S/N) measurement updates as you adjust noise, scan averaging, apodization, FID artifacts, and shimming, making processing tradeoffs easy to compare. Apply zero filling to see how digital interpolation changes the appearance of the spectrum without adding new measured data. You can also introduce common receiver or acquisition faults into the FID and observe the artifacts that appear after processing. As an advanced example, add spin-spin coupling to create an AB coupling pattern, then move the peaks or change the coupling strength to compare AB behavior with an AX spin system. Charts retain every data point and support pan, zoom, phase-pivot dragging, graph audio, sharing and export, and external displays. Optimized Metal and Accelerate processing keeps high-resolution chart and shimming interactions responsive. Adaptive layouts and larger accessibility text make the workspace easier to use on iPhone, iPad, and Mac. Open one-dimensional JEOL, Bruker and Varian FID datasets directly. Inspect the acquired real and imaginary channels, then apply apodization, zero filling, first-point scaling, and zero- and first-order phase correction to your own data.

No Prof você acompanha e faz tarefas escolares em uma interface simples e intuitiva que lhe ajudará a dar aquele ânimo na sua vida acadêmica. Disponibilizamos para o aluno uma agenda que permite fazer e acompanhar as tarefas lançadas pelo professor e suas respectivas datas de entrega. As atividades são sinalizadas com cores que indicam a urgência de entrega, facilitando assim manter sob controle até mesmo aquelas atividades com prazos mais apertados. No Prof o aluno poderá realizar testes de acordo com os livros e assuntos ministrados em sala de aula, reforçando ainda mais o seu aprendizado. Não é preciso fazer o cadastro dos compromissos, basta começar a usar e receber automaticamente as atualizações no APP! Com o recurso "Extra" o aluno pode responder desafios, liberados à medida que ele for indo bem nos testes, como forma de melhorar ainda mais os conhecimentos em determinados tópicos. Há, ainda, a possibilidade de responder reforços, quando o desempenho em um teste for abaixo da média. Nesses dois casos, o aluno é sempre incentivado a dar o seu melhor nos estudos. Através dos relatórios gerados pelo APP, o aluno poderá saber qual o seu ranking em relação aos colegas da escola, desempenho em relação a tópicos específicos de cada matéria, além de acompanhar o seu desempenho pelos históricos de tarefas, módulos e provas. Ainda há a opção dos pais acompanharem o desempenho de seus filhos pelo APP, mantendo-os sempre atualizados e por dentro da real situação escolar dos seus filhos. O objetivo é tornar a vida do estudante mais simples e organizada, disponibilizando recursos para se ter uma vida escolar satisfatória na palma da sua mão.
