The increasing usage of smartphones in everyday tasks has been motivated many studies on energy consumption characterization aiming to improve smartphone devices’ effectiveness and increase user time. In this scenario, it is essential study mechanisms capable characterizing patterns, so smartphones’ components can be adapted promote the best experience with lower consumption. goal build an mode...

Rising energy costs, the shrinking size of mobile devices and political influences have begun to force device and software developers to look at ways in which they can reduce their energy usage. While most energy savings models can be found in how hardware is designed, software plays a key role in how devices can be more energy efficient because software is what ultimately controls the hardware...

spray drying is one of the most important processes applied in the industry. the equipment used in this process evaporates water in a very short time and so, need a lot of energy. in this work, we used microsoft excel as an analysis tool for the optimization of fuel usage in this dryer. we have described the process in terms of thermodynamic calculations and mass and heat balance equations. our...
