Project International School Cidade Viva: Performance Management by Competence

The present article aims to analyze the management process of the collaborators of ths Internacional School Cidade Viva, followed by the proposal to implement the Performance Management by Competence model. In this perspective, the present study, through exploratory research, of qualitative nature, deductive method bibliographic data collection, developed in order to point out the tools of this model and its results so that they can provide performance improvement and increase the level of satisfaction of its collaborators. It should be noted that the International School Cidade Viva is a Third Sector institution, therefore, not for profit. Furthermore, it should be noted that their main mission is to promote the integral education of leaders, so that they are able to serve for God and for the neighbor with excellence and to transform the world through Christian ethics. Finally, in view of the proposed objectives, it was sought to outline mechanisms capable of measuring the professional performance of the collaborators. relating it to the ideal competencies for the exercise of its position / function and for the fulfillment of the organizational objectives, in order to identify performance potentials and weaknesses.

Design Potentials of External Gear Machines With Asymmetric Tooth Profile

This paper describes the design, optimization and the performance potentials of external gear machines with asymmetric tooth profiles. Conventionally, the design of these machines is entirely based on symmetric involute profile. A design method has been developed to derive the tooth profiles based on a modified rack-cutter profile which is assumed to be used for manufacturing the gears with asymmetric involute surfaces and trochoidal fillet profiles. The study is based on the simulation tool HYGESim (HYdraulic GEar machines Simulator) which is being developed and has been validated by the authors’ research group to accurately analyze the performance of the machine. For the purpose of this research, HYGESim was adapted to simulate the particular case of non-symmetric gear profiles. A specific optimization procedure based on genetic algorithm was implemented to find the maximum performance of the new design, in terms of volumetric efficiency, fluid borne noise, internal pressure peaks and localized cavitation acting on the design parameters that characterize the tooth profile. The results of the optimization process are compared to the current state of the art for external gear machines. This comparison show very high potentials for this new design principle, particularly concerning the reduction of the fluid borne noise.

Analysis and Experimentation of Multi-S Rotors for Vertical Wind Turbine Applications

This article presents a new, multi-foil-blades (multi-S) rotor and compare its performance potentials with traditional (Single-S) Savomius rotor . Theoretical and experimental investigations show that the performance of the multi-S rotor is better than the other classical designs of Savonius rotor in terms of the resulting power factor. Analytical equations for power and torque factors are developed for both the single- and multi-S rotors with ideal flow assumed. These equations are proven very effective in describing the performance potentials of these rotors for a range of speed ratio less than or equals 0.7. This result is experimentally justified for both types of rotors. For speed ratios higher than 0.7, a remarkable deviation occurs between the theoretical performance measures provided by the developed equations and the experimentally measured ones. A geometric design parameter which depends on the internal construction of the proposed multi-S rotor is found to be of great impact on the attained power factor. A power factor for the multi-S rotor can be much more than that of a single-S one having the same height and outer size according to the chosen values of this design parameter.
