A stochastic costing model for manufacturing management and control
Vyas, Vishad; Afonso, Paulo; Silva, Sergio; Boris, BretDue to global competition, manufacturing companies need to support decision making on sophisticated, timely and accurate costing systems. Traditional costing methods based on volume measures are not efficient in modern times characterized by product diversity, production complexity and market volatility and uncertainty. Activity-based cost models were introduced in the 1980s and can help to deal with the comple...
Wireless sensors and IoT platform for intelligent HVAC control
Ruano, Antonio; Silva, Sergio; Duarte, Hélder; Ferreira, Pedro M.Energy consumption of buildings (residential and non-residential) represents approximately 40% of total world electricity consumption, with half of this energy consumed by HVAC systems. Model-Based Predictive Control (MBPC) is perhaps the technique most often proposed for HVAC control, since it offers an enormous potential for energy savings. Despite the large number of papers on this topic during the last few ...

The IMBPC HVAC system: a complete MBPC solution for existing HVAC systems
Ruano, Antonio; Pesteh, Shabnam; Silva, Sergio; Duarte, Helder; Mestre, Gonçalo; Ferreira, Pedro M.; Khosravani, Hamid Reza; Horta, RicardoThis paper introduces the Intelligent MBPC (IMBPC) HVAC system, a complete solution to enable Model Based Predictive Control (MBPC) of existing HVAC installations in a building. The IMPBC HVAC minimizes the economic cost needed to maintain controlled rooms in thermal comfort during the periods of occupation. The hardware and software components of the IMBPC system are described, with a focus on the MBPC algorit...
Digital sound processing using arduino and MATLAB
Silva, Sergio; Soares, Salviano; Valente, Antonio; Marcelino, Sylvain T.Over the last decade, impelled by the huge open source software community support, the low cost Arduino platform presents itself as an alternative for digital sound processing. Although Arduino is generally used for small applications for the artistic and maker community, its built-in Analog to digital converter can be used for sound capturing, processing and reproduction. Equipped with a powerful AVR 8 bit RIS...
An Intelligent Weather Station
Mestre, Goncalo; Ruano, Antonio; Duarte, Helder; Silva, Sergio; Khosravani, Hamid Reza; Pesteh, Shabnam; Ferreira, Pedro M.; Horta, RicardoAccurate measurements of global solar radiation, atmospheric temperature and relative humidity, as well as the availability of the predictions of their evolution over time, are important for different areas of applications, such as agriculture, renewable energy and energy management, or thermal comfort in buildings. For this reason, an intelligent, light-weight, self-powered and portable sensor was developed, u...
