Scatter correction in SPECT quantification is of major importance to compensation for the scatter contribution under the photopeak. The triple energy windows method (TEW) is one of the suggested ways for scatter correction that are widely used in clinical... see more

Wind energy is renewable energy used as an energy source for wind power plants (PLTB). The most common distribution method used to model wind speed distribution data is the Weibull distribution. The Nakagami distribution has begun to be widely used in sev... see more

Due to the emerging needs in parallel with the developing technology and industrialization, the importance of renewable energy sources is increasing with the decrease of usable fossil resources and the ever-increasing need for energy. For this reason, sol... see more

A large portion of the energy consumed worldwide is used for heating and cooling environments. In Brazil, the use of solar energy in homes experiences an increasing, despite the fact that not always an exclusively solar system can meet the entire energy d... see more

This study investigates the use of clustering methodologies as a means of reducing spatio-temporal wind speed data into statistically representative classes of temporal profiles for further processing and interpretation. The clustering methodologies ... see more

In the context of the Anthropocene, the decoupling of carbon emissions from electricity generation is critical. South Africa has an ageing coal power fleet, which will gradually be decommissioned over the next 30 years. This creates substantial opportunit... see more

Flettner rotor is a cylindrical object which installed vertically on the ship's body. It rotates on its axis to utilize the airflow from the wind and help the ship to generate additional thrust force by using the principle of magnus effect. This additiona... see more

The spatial interpolation and mapping of renewable energy resources is an important task of potential estimation of atmospheric renewable energy sources. First the global radiation on horizontal surfaces and near-surface wind speed at 10 m height above th... see more
