Domande frequenti
Come faccio ad annullare l'abbonamento?
È semplicissimo: basta accedere alla sezione Account nelle Impostazioni e cliccare su "Annulla abbonamento". Dopo la cancellazione, l'abbonamento rimarrà attivo per il periodo rimanente già pagato. Per maggiori informazioni, clicca qui
È possibile scaricare libri? Se sì, come?
Al momento è possibile scaricare tramite l'app tutti i nostri libri ePub mobile-friendly. Anche la maggior parte dei nostri PDF è scaricabile e stiamo lavorando per rendere disponibile quanto prima il download di tutti gli altri file. Per maggiori informazioni, clicca qui
Che differenza c'è tra i piani?
Entrambi i piani ti danno accesso illimitato alla libreria e a tutte le funzionalità di Perlego. Le uniche differenze sono il prezzo e il periodo di abbonamento: con il piano annuale risparmierai circa il 30% rispetto a 12 rate con quello mensile.
Cos'è Perlego?
Perlego è un servizio di abbonamento a testi accademici, che ti permette di accedere a un'intera libreria online a un prezzo inferiore rispetto a quello che pagheresti per acquistare un singolo libro al mese. Con oltre 1 milione di testi suddivisi in più di 1.000 categorie, troverai sicuramente ciò che fa per te! Per maggiori informazioni, clicca qui.
Perlego supporta la sintesi vocale?
Cerca l'icona Sintesi vocale nel prossimo libro che leggerai per verificare se è possibile riprodurre l'audio. Questo strumento permette di leggere il testo a voce alta, evidenziandolo man mano che la lettura procede. Puoi aumentare o diminuire la velocità della sintesi vocale, oppure sospendere la riproduzione. Per maggiori informazioni, clicca qui.
Mastering Gephi Network Visualization è disponibile online in formato PDF/ePub?
