Differential diagnosis between urticarial vasculitis and chronic spontaneous ur...
Krause, Karoline; Bonnekoh, Hanna; Jelden-Thurm, Jannis; Asero, Riccardo; Gimenez-Arnau, Ana Maria; Cardoso, José C.; Grattan, Clive; Kocatürk, EmekBackground: Urticarial vasculitis (UV) should be differentiated from chronic spontaneous urticaria (CSU) in patients initially presenting with recurrent wheals, although criteria for differential diagnosis remain ill‐defined. Objectives: To set the goals, define criteria and unmet needs in UV diagnosis and differential diagnosis with CSU, and explore the possibility of coexistence of both diseases. Methods: Thi...
Can based domotic system using TMS320F243 controller
Metrôlho, J.C.M.M.; Pereira, António; Costa, Mónica; Cardoso, José C.; Lopes, EuricoThe increasing demand of comfort levels in the home area stimulates the development of systems to reach several goals. Some features of this kind of systems are: energy savings, environmental control, safety monitoring, remote definition of the system set points, etc. This kind of systems is made up of several units spread in the target areas of the house where they are implemented. Those units communicate betw...
Doppler time-frequency estimators: cost/benefit analysis
Cardoso, José C.; Fish, Peter J.; Ruano, M. GraçaWe apply a selection criterion for Doppler spectral estimators that takes into account the accuracy of the estimation, benefit, and also the `cost' in computation power required. This cost/benefit criterion is used to compare four time-frequency distributions (TFD) including the conventional short-term Fourier transform (STFT).
Doppler bandwidth and mean frequency from time-frequency estimators
Cardoso, José C.; Ruano, M. Graça; Fish, PeterThe performances of various time-frequency distribution (TFD) methods in the estimation of mean frequency and spectral bandwidth of the nonstationary Doppler blood flow signal are compared using simulated signals with known characteristics and different signal to noise ratios.
