O registo só é necessário para efetuar a reserva antecipada da "sala de controlo" das experiencias, por exemplo para ter a garantia futura da sua disponibilidade em sala de aula. Caso contrario, para os utilizadores comuns, é suficiente indicar um nome de utilizador e prosseguir com o lançamento da plataforma (deixando a palavra-passe em branco) sendo o acesso efetuado numa base primeiro-a-chegar-primeiro-a-ser-servido.

Frequently asked questions about e-lab.

About e-lab

How do I register? Do I NEED to register to use e-lab?

Registering is only necessary to make a reservation, for instance, if you wish to ensure access to a certain experiment at a certain date. If that's not the case, all users need only to choose a name for themselves (the password field remains blank). Access to e-lab is first-come-first-served.

How do I make a reservation?

Currentlly, IST does not have a reservation policy, but maintains the right to do so, with regular access maintained, if possible.

Are the experiments recorded previously?

Nope. All e-lab experiments run live as soon as the user clicks the "play" button (unless there are users waiting in queue). There are, however, some virtual labs with simulated experiments. In this case, the e-lab platform will have a different background color and is shown in a different window.

Why is there a waiting queue to use a certain experiment? Do I always have to wait in line?

Because there are physical setups for each experiment (and some setups serve multiple experiments), there can be only one user active user at a given moment. This means that when you press play, you will be put in a queue. When it's your turn, the software automatically runs the experiment with the parameters you have chosen. When it's done, it shows you the results and moves on to the next user. However, the data each user took is available to all users, so if someone else runs the experiment the parameters you want, you can access and use their data.

Is there ans open acess platform to help me process the experimental data?

Yes, fitteia. This platform has graphical fitting for functions, you just have to register for a (free) account.

Exactly what does the “elab.ist.utl.pt:9001 not ok” message mean?

This means that you are running e-lab a computer located behind a firewall, meaning the access ports used by e-lab (9001,9002 and 9003) are not available. This is common practice in some networks with overzealous network administrators (or of the computer itself). To access e-lab, you must ask you network administrator to open these ports or use a computer with less restrictions.


Before using e-lab

Java

Official website

What is Java?

Do site oficial: O Java é uma tecnologia usada para desenvolver aplicações que tornam a Web mais divertida e útil. O Java não é a mesma coisa que o javascript, que é uma tecnologia simples usada para criar páginas Web e só é executado no seu browser. O Java permite executar jogos, fazer upload de fotos, falar on-line, fazer tours virtuais e usar serviços, como treino on-line, transações bancárias e mapas interactivos. Se você não tiver o Java, muitas aplicações e websites simplesmente não funcionarão.

Nesta página do site oficial pode verificar qual a versão do Java instalado no seu pc.

Onde posso ir buscar a versão correcta da Java Runtime Environment para o meu ambiente?

Normalmente, o próprio browser (o programa que usa para navegar na Internet) consegue perceber qual a versão mais indicada para o seu sistema. Se isto não acontecer, deverá dirigir-se ao site oficial para poder instalar a versão mais recente.

Live Stream

O que é uma live stream?

Normalmente, o Java

Como posso ver as live streams do e-lab?

A equipa e-lab recomenda o VLC.

Onde posso encontrar o VLC para download?
