Artificial Intelligence Applied to Project Success: A Literature Review
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 2015)Project control and monitoring tools are based on expert judgement and parametric tools. Projects are the means by which companies implement their strategies. However project success rates are still very low. This is a ... -
Auto-adaptative Robot-aided Therapy based in 3D Virtual Tasks controlled by a Supervised and Dynamic Neuro-Fuzzy System
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 03/2015)This paper presents an application formed by a classification method based on the architecture of ART neural network (Adaptive Resonance Theory) and the Fuzzy Set Theory to classify physiological reactions in order to ... -
Ball convergence for Steffensen-type fourth-order methods
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 2015)We present a local convergence analysis for a family of Steffensen-type fourth-order methods in order to approximate a solution of a nonlinear equation. We use hypotheses up to the first derivative in contrast to earlier ... -
Building Real-Time Collaborative Applications with a Federated Architecture
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 2015)Real-time collaboration is being offered by multiple libraries and APIs (Google Drive Real-time API, Microsoft Real-Time Communications API, TogetherJS, ShareJS), rapidly becoming a mainstream option for webservices ... -
Checking RTECTL properties of STSs via SMT-based Bounded Model Checking
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 2015)We present an SMT-based bounded model checking (BMC) method for Simply-Timed Systems (STSs) and for the existential fragment of the Real-time Computation Tree Logic. We implemented the SMT-based BMC algorithm and compared ... -
Differences in Measuring Market Risk in Four Subsectors of the Digital Economy
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 03/2015)This paper defends the wisdom of not considering the Digital Economy to be one homogeneous sector. Our hypothesis is that it is best to consider it the result of adding four different subsectors. We test whether indeed the ... -
Editor's Note
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 03/2015)The term 'Digital Economy' was coined for the first time by Don Tapscott in 1995 in his best-seller The Digital Economy: Promise and Peril in the Age of Networked Intelligence. When he wrote the book 20 years ago, he ... -
