This research came from the need to find a pertinent methodology to measure the Sustainable Development of a particular productive sector, which would reflect the reality of the people who belong to that sector. The ...

This research determines if there are benefits if SIEFORE SB1, SB2, SB3 and SB4 invest the variable income component, given by their investment policy authorized by CONSAR, in Mexican companies classified as socially ...

In the draft tube of an hydraulic turbine the kinetic energy of the flow is transformed into pressure. This energy conversion significantly impacts on the efficiency and power output of the turbines and mostly those that ...

Laelia autumnalis is a wild orchid with ornamental potential due to the attractive characteristics of its flowers. However, it is necessary to induce variability of commercial interest in this species to generate varieties ...

According to the theory of Umwelt by Jakob von Uexküll (1926) the individual lives in a surrounding world from which he receives the signs that are interpreted to understand and establish his relationship with it. Jesper ...

We present results of the static and electromagnetic properties of the pseudo-mescal mesons, vector and diquarks correlations based in a contact interaction. A basic motivation of this study is the need to document a ...

The aim of this thesis is the proposal of a power flow and a static state estimation approaches suitable for electric power transmission systems containing fully controlled multi-terminal high voltage direct current networks. ...

Factors such as energy consumption growth, energy resources depletion and associated environmental impacts, have led to search alternatives such as renewable energies and efficient energy systems integration. Among ...

In the search for the best energy exchange of the fluid in the hydraulic turbine, the greatest efforts have been concentrated in the runner blades, which has caused that the geometric designs of the runner blades are ...

This thesis proposes the development of the attractive ellipsoid method to solve regulation and trajectory tracking problems for nonlinear systems, and its application to electrical microgrids components, mainly those based ...
