Hydrological processes that occur in constructed wetland study systems (CWs) are considered difficult to determine and, consequently, there are few on the subject. Evapotranspiration and different local variables in CWs ...

This work presents the development of an standalone street lighting system based on solar energy and light emitting diodes (LEDs). The system must be able to charge a battery bank during the day from a photovoltaic source ...

A pavement is caracterizes by a set of layers of finite thicknesses, which are intended to resis the demands generated by vehicle traffic. Among the types of coating are the interlocking blocks, concrete blocks that When ...

In this work the optimal trajectory of orbital insertion of a Rocket-Powered Launcher is calculated, considering the discontinuities caused by the stage shifts, via the optimal control theory. First the translational ...

The growing demand for renewable energy drives wind exploration in Brazil and worldwide. This market calls wind turbines manufacturers for longer-lasting, more efficient and larger structures and equipment to harness ...

According to the IBGE-Brazil survey, the number of application drivers, taxi drivers, bus drivers and bus changers increased by 29.2 % in 2018 and reached 3.6 million. This indicates that the number of people operating in ...

The constant increase in the price of petroleum-derived fuels during the pandemic period and the need to reduce greenhouse gas emissions demand more efficient spark-ignition combustion engines. Governmental programs such ...

With the growing interest of consumers of electric energy for the benefits brought by the Distributed Generation (DG), there is a concern about the impact that such insertion will bring to the distribution networks. After ...

This work presents a comparative analysis in terms of efficiency and losses estimation between a power control (PC) stage of a commercial LED luminaire, which uses Silicon (Si) transistors, with respect to two prototypes ...

This work deals with a predictive finite set control together with the Instantaneous Power Theory (p-q theory) for parallel compensation of an distributed off-grid generation system based on a self-excited induction ...
