On bounding a nonlinear system with a monotone positive system
(2017-12)"How to bound the state vector trajectory of a nonlinear system in a way so that the obtained bound be of practical value is an open problem. If some norm is employed for bounding the state vector trajectory, then this ... -
Study on spike-and-wave detection in epileptic signals using T-location-scale distribution and the K-nearest neighbors classifier
(2017-12)"Pattern classification in electroencephalography (EEG) signals is an important problem in biomedical engineering since it enables the detection of brain activity, in particular the early detection of epileptic seizures. ... -
Performing OLAP over graph data: query language, implementation, and a case study
(2017)"In current Big Data scenarios, traditional data warehousing and Online Analytical Processing (OLAP) operations on cubes are clearly not sufficient to address the current data analysis requirements. Nevertheless, OLAP ... -
Fault tolerant control of an hexacopter with a tilted-rotor configuration
(2017)"Recently, it was shown that an hexagon-shaped hexa-rotor micro aerial vehicle with unidirectionally spinning tilted rotors is capable of fault tolerant attitude and altitude control. This result has been theoretically ... -
A chopped front-end system with common-mode feedback for real time ECG applications
(2017)"A Front-End system composed of an instrumentation amplifier with common-mode feedback and a second-order sigma-delta analog to digital converter is proposed. Chopping techniques are used to remove offset and lowfrequency ...
