CrimAnalyzer: Understanding Crime Patterns in São Paulo.

São Paulo is the largest city in South America, with crime rates that reflect its size. The number and type of crimes vary considerably around the city, assuming different patterns depending on urban and social characteristics of each particular location. Previous works have mostly focused on the analysis of crimes with the intent of uncovering patterns associated to social factors, seasonality, and urban routine activities.

H-Sliding mode control of one-sided Lipschitz nonlinear systems subject to input nonlinearities and polytopic uncertainties.

This paper is concerned with the control problem for different types of one-sided Lipschitz (OSL) nonlinear systems subject to input nonlinearities, unmatched polytopic uncertainties and external perturbations. The design framework gathers the high robustness qualities of the sliding mode control (SMC) and the H technique. The aims is to consider the bounded L disturbance attenuation measure in the analysis of sliding mode dynamics, thus to ameliorate the performance of the SMC system.

Variable speed wind turbine control by discrete-time sliding mode approach.

The aim of this paper is to propose a new design variable speed wind turbine control by discrete-time sliding mode approach. This methodology is designed for linear saturated system. The saturation constraint is reported on inputs vector.
