RenderScript is a set of tools designed by Google to support parallel processing on mobile devices with Android. This tools were designed to run on dierent processing components such as Central Processing Units (CPU), Digital Signal Processors (DSP) and Graphics Processing Units (GPU) and it allows portability between mobile electronics devices such as(More)
This paper provides a computational analysis of wind impact on different geometric configurations of Savonius turbines proposed and previously studied in specialized literature. As a result of comparative analysis of turbines, we performed a flow analysis over a micro-turbine array, proposed a twisted Savonius turbine respecting its original profile, and(More)
The calculation of Normalized Difference Vegetation Index (NDVI) has been studied in literature by multiple authors inside the remote sensing field and image processing field, however its application in large image files as satellite images restricts its use or need prepro-cessed phases to compensate for the large amount of resources needed or the(More)
This paper presents a hierarchical control system designed for permanent DC motor powered by a DC/DC Buck converter. Hierarchical controller based on differential flatness property of the plant system is meant to control the angular speed for tracking trajectories applications. This controller provides the voltage profiles that have to be tracked by the(More)
Island model deals with a species which is subdivided into a number of discrete finite populations, races or subspecies, between which some migration process occurs. If the number of populations is small, an assumption of equal rates of migration between each pair of populations may be reasonable approximation. In this paper we shown a general solution is(More)
