We developed, implemented, and evaluated a myocardial infarction (MI) adjudication protocol for cohort research of human immunodeficiency virus. Potential events were identified through the centralized Centers for AIDS Research Network of Integrated Clinical Systems data repository using MI diagnoses and/or cardiac enzyme laboratory results (1995-2012).(More)
This paper assesses the main challenges associated with the propagation and channel modeling of broadband radio systems in a complex environment of high speed and metropolitan railways. These challenges comprise practical simulation, modeling interferences, radio planning, test trials and performance evaluation in different railway scenarios using Long Term(More)
This work presents measured and simulated results of indoor radio channel characterization in Femtocells in auditorium at the Catholic University of Rio de Janeiro (PUC-Rio) at 1.95 GHz. The measurement campaign used the time domain sounding technique using PN-sequence with a matched filter, the correlation was implemented offline. The simulation used the(More)
This paper presents the statistical analysis of measured propagation data in a femtocell indoor radio environment. Measurements were performed at 1.95 GHz with a 160 MHz channel bandwidth. Time domain sounding technique using PN-sequence with a matched filter was employed. Empirical and theoretical prediction using the Saleh Valenzuela model and the(More)
Discrete Event Simulation (DES) is a powerful tool of modeling and analysis used in different disciplines. DES projects rely heavily on data in order to compute different parameters that drive the simulations. DES is usually performed on specialized DES software, which performs the simulations but does not prepare the data to set up the simulations.(More)
