Abstract Determinate the runoff of a watershed is challenge due to complexity representing all “inlets” and “outlets” involved in rainfall–runoff model. Therefore, methodologies applied for this purpose should have good representation variables that most influence process. One models used calculate design flow (USDA Urban Hydrology Small. Technical release, no 55 (TR-55). Soil Conservation Serv...

The Kaplan-Meier (KM) method is used to analyze 'time-to-event' data. The outcome in KM analysis often includes all-cause mortality, but could also include other outcomes such as the occurrence of a cardiovascular event. The purpose of this article is to explain the basic concepts of the KM method, to provide some guidance regarding the presentation of the KM results and to discuss some importa...

This study makes use of an energy balance to identify damping parameters in mechanical vibration systems. By balancing the energy input as registered in the force-displacement relationship of the real system against the energy lost theoretically in a damping model with unknown parameters, the identification algorithms are developed. We apply the estimation equations to both numerical and experi...

An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the synchronized measurements of complex currents and complex voltages at the sending and receiving ends of transmission systems. The synchronized measurements can be in practice o...

The Kaplan-Yorke conjecture suggests a simple relationship between the fractal dimension of a system and its Lyapunov spectrum. This relationship has important consequences in the broad field of nonlinear dynamics where dimension and Lyapunov exponents are frequently used descriptors of system dynamics. We develop an experimental system with controllable dimension by making use of the Kaplan-Yo...
