The aim of this work is to develop a remote supervision system that establishes communication between the electronic control unit of an electricity generating set and a SCADA supervision programme. The supervisory system was developed for this project in the PHP language, running remotely on a server machine. A Modbus TCP/IP master developed in Java language is also implemented on the server. The information is stored in an SQL database, making the data available to the supervisory system. The Modbus RTU bus data collection hardware was designed on a printed circuit board, where the microcontroller and the circuits, both the power supply and those used for communication between the microcontroller and the bus, are arranged. Sockets with information in the Modbus TCP/IP protocol are used to send information from the generators, using an IEEE 802.11 network. The system developed was validated with tests on an electricity generator, which is presented in this paper. The results obtained in the tests showed that the system is capable of performing the operations it was designed to perform.

This work presents a proposal for monitoring and forecasting the level of the Amazon River in the city of Santarém, using an ANFIS approach and historical data on the annual fluviometric cycle. The data was collected in the cities of Santarém, Manaus and Itaituba, and was filtered to the period from 01/03/03 to 28/02/17. The data was analysed in order to establish threshold values for alerts of emerging situations for monitoring the river level, comprising the times of the water volumes: drought, drought-normal, normal, normal-full and flood. The historical series can be considered reliable, as it is possible to clearly identify the annual hydrological cycles of the rivers. Predictive solutions using statistical and computational techniques are capable of automating such forecasts with relatively low rates of river level error. With this in mind, it is considered that the proposed solution can be used to guide actions that minimise the disruption caused to the city of Santarém in extreme situations of the Amazon River's water volumes. The proposed approach has also been shown to be applicable in other environments with hydrological cycles and, therefore, possible global applicability.

Con l'espansione della tecnologia e il crescente accesso alle applicazioni esistenti su Internet, è diventata una sfida mantenerle sempre disponibili. Questo lavoro si propone di dimostrare in teoria e in pratica l'uso di risorse per scalare un'applicazione web e ottenere un'elevata disponibilità. Queste risorse possono essere applicate direttamente all'applicazione, ad esempio utilizzando Ajax, oppure possono essere applicate all'architettura dei server che renderanno disponibile l'applicazione, utilizzando i concetti di scalabilità verticale, clusterizzazione e scalabilità orizzontale. Vengono inoltre illustrate le tecniche per aumentare le prestazioni delle applicazioni web.

Questo lavoro presenta una proposta di monitoraggio e previsione del livello del Rio delle Amazzoni nella città di Santarém, utilizzando un approccio ANFIS e dati storici sul ciclo fluviometrico annuale. I dati sono stati raccolti nelle città di Santarém, Manaus e Itaituba e sono stati filtrati per il periodo compreso tra il 01/03/03 e il 28/02/17. I dati sono stati analizzati al fine di stabilire valori soglia per l'allerta di situazioni emergenti per il monitoraggio del livello del fiume, comprendendo i tempi dei volumi d'acqua: siccità, siccità-normale, normale, normale-pieno e alluvione. Le serie storiche possono essere considerate affidabili, in quanto è possibile identificare chiaramente i cicli idrologici annuali dei fiumi. Le soluzioni predittive che utilizzano tecniche statistiche e computazionali sono in grado di automatizzare tali previsioni con tassi di errore relativamente bassi del livello del fiume. Per questo motivo, si ritiene che la soluzione proposta possa essere utilizzata per guidare azioni che riducano al minimo i disagi causati alla città di Santarém in situazioni estreme di volumi d'acqua del Rio delle Amazzoni. È stato inoltre dimostrato che l'approccio proposto è applicabile anche in altri ambienti con cicli idrologici e, quindi, di possibile applicabilità globale.

L'objectif de ce travail est de développer un système de supervision à distance qui établit une communication entre l'unité de contrôle électronique d'un groupe électrogène et un programme de supervision SCADA. Le système de supervision a été développé pour ce projet en langage PHP, fonctionnant à distance sur une machine serveur. Un maître Modbus TCP/IP développé en langage Java est également implémenté sur le serveur. Les informations sont stockées dans une base de données SQL, ce qui rend les données disponibles pour le système de supervision. Le matériel de collecte des données du bus Modbus RTU a été conçu sur une carte de circuit imprimé, où sont disposés le microcontrôleur et les circuits, tant l'alimentation que ceux utilisés pour la communication entre le microcontrôleur et le bus. Des prises avec des informations dans le protocole Modbus TCP/IP sont utilisées pour envoyer des informations depuis les générateurs, en utilisant un réseau IEEE 802.11. Le système développé a été validé par des tests sur un générateur d'électricité, qui est présenté dans cet article. Les résultats obtenus lors des tests ont montré que le système est capable d'effectuer les opérations pour lesquelles il a été conçu.

Avec l'expansion de la technologie et l'accès croissant aux applications existantes sur Internet, il est devenu difficile de les maintenir disponibles à tout moment. Ce travail vise à démontrer, en théorie et en pratique, l'utilisation de ressources pour faire évoluer une application web et atteindre une haute disponibilité. Ces ressources peuvent être appliquées directement à l'application, par exemple en utilisant Ajax, ou elles peuvent également être appliquées à l'architecture des serveurs qui rendront l'application disponible, en utilisant les concepts d'extensibilité verticale, de clusterisation et d'extensibilité horizontale. Il présente également des techniques permettant d'augmenter les performances des applications web.

Ce travail présente une proposition de surveillance et de prévision du niveau du fleuve Amazone dans la ville de Santarém, en utilisant une approche ANFIS et des données historiques sur le cycle fluviométrique annuel. Les données ont été collectées dans les villes de Santarém, Manaus et Itaituba, et ont été filtrées pour la période allant du 01/03/03 au 28/02/17. Les données ont été analysées afin d'établir des valeurs seuils pour les alertes de situations émergentes pour la surveillance du niveau de la rivière, comprenant les périodes des volumes d'eau : sécheresse, sécheresse-normale, normale, normale-pleine et inondation. Les séries historiques peuvent être considérées comme fiables, car il est possible d'identifier clairement les cycles hydrologiques annuels des rivières. Des solutions prédictives utilisant des techniques statistiques et informatiques sont capables d'automatiser de telles prévisions avec des taux d'erreur relativement faibles sur le niveau des rivières. Dans cette optique, on considère que la solution proposée peut être utilisée pour guider les actions qui minimisent les perturbations causées à la ville de Santarém dans des situations extrêmes de volumes d'eau du fleuve Amazone. L'approche proposée s'est également avérée applicable à d'autres environnements avec des cycles hydrologiques et, par conséquent, une applicabilité mondiale possible.
