Technology assessment for power quality mitigation devices - Micro-DVR case study

This work presents a case study on technology assessment for power quality devices. A system compatibility test protocol for power quality mitigation devices was developed in order to evaluate the functionality of three-phase voltage restoration devices. In order to case test this test protocol, a development platform with reduced power for DVR (Dynamic Voltage Restorer), the Micro-DVR, was tested, and results were discussed based on voltage disturbances standards. ©2008 IEEE.

Trabalho de docência e comportamento micro-organizacional: A motivação do docente na área da saúde

Using the motivograma and interviews the degree of motivation of the survey participants was defined as satisfactory. On one hand there is satisfaction with the physiological needs, self-esteem and self confidence, on the other there is high dissatisfaction with the association and self-realization, justifying the request for strengthening the membership and performance improvements in the research area. Linking up security and association with the other ones group protection sentiments and work environment dependence sentiments prevail. It was concluded that: (1) Those satisfied ones declare that they are safe, protected and with good self-esteem doing their teaching work. The ones dissatisfied with the non-group belonging demonstrate dissatisfaction with the self-realization and expose their difficulties with social ties and the lack of integration in the teaching work. (3) The degree of motivation satisfactory is related to the satisfaction of basic needs, located in the first steps of Maslow's hierarchy. Accepting that the changes in higher education require motivated behaviors, the question arises: how can the motivation in teaching work be possible if the majority of organizations do not find a way to deal with the person of the Professor? Finally, the context of work is predominant in the provision of job satisfaction in teaching.

Development of a micro heat exchanger made with ceramic multi-layers (LTCC) and its setup to gas flow measurements

A green ceramic tape micro heat exchanger was developed using LTCC technology. The device was designed by using a CAD software and 2D and 3D simulations using a CFD package (COMSOL Multiphysics) to evaluate the fluid behavior in the microchannels. The micro heat exchanger is composed of five thermal exchange plates in cross flow arrangement and two connecting plates; heat exchanger dimensions are 26 × 26 × 6 mm3. Preliminary tests were carried out to characterize the device both in atmospheric pressure and in vacuum. The same techniques used in vacuum technology were applied to check the rotameters and to prevent device leakages. Thermal performance of the micro heat exchanger was experimentally tested. © 2009 Elsevier B.V. All rights reserved.

Swarm control designs applied to a micro-electro-mechanical gyroscope system (MEMS)

This paper analyzes the non-linear dynamics of a MEMS Gyroscope system, modeled with a proof mass constrained to move in a plane with two resonant modes, which are nominally orthogonal. The two modes are ideally coupled only by the rotation of the gyro about the plane's normal vector. We demonstrated that this model has an unstable behavior. Control problems consist of attempts to stabilize a system to an equilibrium point, a periodic orbit, or more general, about a given reference trajectory. We also developed a particle swarm optimization technique for reducing the oscillatory movement of the nonlinear system to a periodic orbit. © 2010 Springer-Verlag.
