Conhecimento tecnológico e inovação no Brasil: Um estudo patentométrico na universidade estadual paulista

The patent recordings of the Universidade Estadual Paulista (UNESP) since its first recording in 1980 to December 2010 are analysed, in order to promote their visibility, and analyze their authors, most productive areas and most common themes. As research procedure, we verified the relation of all patents deposited, following different types: patent recordings of invention, utility models, brands and industrial drawings, all of which were obtained from the Unesp Innovation Agency. Finally, the scientific colaboration network among the researchers was drawn using PAJEK. The most productive authors are grouped in the Araraqua Chemistry Institute and the engeneering area.

On Non-ideal and Chaotic Energy Harvester Behavior

In this paper, we deal with the research of a proposed mathematical model of energy harvesting, including nonlinearities in the piezoelectric coupling and a non-ideal force of excitation. We showed using numerical simulations to analysis of the dynamic responses that, the power harvested was influenced by the nonlinear vibrations of the structure, as well as by the influence of the non-linearities in the piezoelectric coupling. We concluded through of the numerical results that the limited energy source was interacting with the system. Thus, the increasing of the voltage in DC motor led the system produce a good power response, especially in high-energy orbits in the resonance region, but the Sommerfeld effect occurs in the system and a chaotic behavior was found in the post-resonance region. So the power harvested along the time decreases because occurs loses of energy due the interaction between energy source and structure. Keeping the energy harvested constant over time is essential to make possible the use of energy harvesting systems in real applications. To achieve this objective, we applied a control technique in order to stabilize the chaotic system in a periodic stable orbit. We announced that the results were satisfactory and the control maintained the system in a stable condition. © 2012 Foundation for Scientific Research and Technological Innovation.

On the Chaotic Suppression of Both Ideal and Non-ideal Duffing Based Vibrating Systems, Using a Magnetorheological Damper

In this paper the dynamics of the ideal and non-ideal Duffing oscillator with chaotic behavior is considered. In order to suppress the chaotic behavior and to control the system, a control signal is introduced in the system dynamics. The control strategy involves the application of two control signals, a nonlinear feedforward control to maintain the controlled system in a periodic orbit, obtained by the harmonic balance method, and a state feedback control, obtained by the state dependent Riccati equation, to bring the system trajectory into the desired periodic orbit. Additionally, the control strategy includes an active magnetorheological damper to actuate on the system. The control force of the damper is a function of the electric current applied in the coil of the damper, that is based on the force given by the controller and on the velocity of the damper piston displacement. Numerical simulations demonstrate the effectiveness of the control strategy in leading the system from any initial condition to a desired orbit, and considering the mathematical model of the damper (MR), it was possible to control the force of the shock absorber (MR), by controlling the applied electric current in the coils of the damper. © 2012 Foundation for Scientific Research and Technological Innovation.

Latin America and the Caribbean in the World Economy: 2005 Trends

The study recently published by the Division of International Trade and Integration of ECLAC considers that 2005 will be a good year for trade in the countries of the region. Despite a favourable international context, there are still serious problems of competitiveness. The region needs to increase productivity, promote technological innovation and take a proactive part in worldwide networks. The conclusions of the study include the need to update integration; to take a strategic view of the links to be constructed with China and the countries of the Pacific; to manage free-trade agreements so as to increase and diversify exports; to step up the pace of work and improve coordination with the developing countries on the Doha Round, and to gradually incorporate the demands of security into competitiveness policies, ensuring that they do not become protectionist barriers (traceability, food safety and maritime and port security).
