As constantes de acidez do PAR foram determinadas por Análise de Componentes Principais em Rede Neural Artificial, usando-se dados espectrais simulados e experimentais. As equações de balanço de massa do ácido triprótico e os perfis espectrais correspondentes, gerados por um modelo Gaussiano, foram usados para simular todos os dados de absorbância-pH necessários. Um ruído constante, com média z...

Artificial Neural Networks (ANN) have recently been used in modeling the mechanical behavior of fiber-reinforced composite materials. The use of ANN in predicting fatigue failure in composites would be of great value if one could predict the failure of materials other than those used for training the network. This would allow developers of new materials to estimate in advance the fatigue proper...

The relevance of this paper in today’s ICT driven society is to ensure that PC buyers are assisted on decision making in PC purchasing. Development of an artificial intelligence advisory system (AIAS) that uses artificial neural network (ANN) as its knowledge base appears to be a promising method for offering expert advise to intended PC users such as schools, organizations, banks and the amate...

Predicting stock price movements is a challenging task for academicians and practitioners. In particular, forecasting price movements in emerging markets seems to be more elusive because they are usually more volatile often accompanied by thin trading-volumes and they are susceptible to more manipulation compared to mature markets. Technical analysis of stocks and commodities has become a scien...

in this work, the pc-saft equation of state (eos) has been used to model the solubility of acid gases (co2 and h2s) in two imidazolium-based ionic liquids (ils) ([c8-mim][pf6] and [c8-mim][tf2n]). parameters of pure ils were estimated using experimental densities. two strategies were considered to model densities of pure ils. in strategy 1, ils were modeled as nonassociating compounds and in st...

in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...

Intelligent Space is a space, which has distributed sensory intelligence and it is equipped with actuators. The various devices of sensory intelligence cooperate with each other autonomously yielding high intelligence in the space. Each intelligent agent in the Intelligent Space knows its role and can support human beings. The most important source of information in Intelligent Space are camera...
