Development of a library for clients of ONVIF video cameras: challenges and sol...
Lopes, Sérgio F.; Silva, Sérgio; Mendes, José; Metrôlho, José Carlos; Duque, DuarteThe interoperability of IP video equipment is a critical problem for surveillance systems and other video application developers. ONVIF is one of the two specifications addressing the standardization of networked devices interface, and it is based on SOAP. This paper addresses the development of an ONVIF library to develop clients of video cameras. We address the choice of a web services toolkit, and how to...
A bluetooth-based Interactive system to improve relationships between actors in...
Ribeiro, F. Reinaldo; Metrôlho, José; Costa, MónicaNowadays there are a vast number of devices and technologies available for the common citizen to improve their communication with others. This fosters the design and implementation of systems that explore the available features of these devices. In this paper, we propose a Bluetooth-based interactive system for delivering personalized information in high education institutions. The system allows informing, on a...
A target environment programming language to improve developer's productivity: ...
Metrolho, José; Costa, Mónica; Ribeiro, F. Reinaldo; Lopes, EuricoThis paper presents a target-specific programming language (TSL) that was designed to improve the design cycle of code generation for an industrial embedded system. The native assembly code, the new language structure and their constructs, are presented in the paper. The proposed TSL is expressed using words and terms that are related to the target’s domain and consequently it is now easier to program, understa...

Ribeiro, F. Reinaldo; Metrôlho, José; Costa, MónicaNowadays there are a vast number of devices and technologies available for the common citizen to improve their communication with others. This fosters the design and implementation of systems that explore the available features of these devices. This paper presents a system that allows to inform, on a personalized way, the actors of an education institution on a free way using popular communication standards. F...
MiADL : linguagem para geração automática de simuladores redireccionáveis
Metrôlho, José Carlos Meireles MonteiroTese de Doutoramento em Electrónica Industrial - Área de Conhecimento em Informática Industrial ; Os sistemas embutidos, além de fazerem cada vez mais parte da vida do cidadão comum, são dispositivos cada vez mais sofisticados e complexos. As equipas de desenvolvimento de sistemas embutidos têm por isso de lidar com complexidade crescente para atingir performances e requisitos cada vez mais exigentes (ex. hier...
Web-CAN interface for access control and monitoring
Ribeiro, F. Reinaldo; Metrôlho, José; Lopes, EuricoThis paper describes a web-based system which allows the user to manage and to do real time monitoring the access to the educational building spaces, using two data nets. The first one is based on the CAN bus for data acquisition and actuation tasks to which are connected control devices like, magnetic cards readers, door locks and sensors. The second one is an Internet/Intranet infrastructure and uses standard...
Rede CAN para comando de actuadores em estufas agricolas
Metrôlho, José Carlos Meireles MonteiroMestrado em Electrónica Industrial ; A crescente importância da utilização de estufas, devido à necessidade de obter com êxito, culturas em ambientes e/ou épocas, que à partida não seriam as mais favoráveis, exige que se desenvolvam sistemas para controlar algumas grandezas consideradas importantes tais como, a temperatura, humidade, radiação solar, etc. No âmbito desta dissertação, pretende-se efectuar o cont...
