Microstructural characterization of Ti-added ultra-low carbon interstitial-free steel submitted by drawing test
(Electron Microscopy 1998, Vol 2, 1998-01-01) [Trabalho apresentado em evento]
Cogeneration system design optimization
(American Society of Mechanical Engineers, Advanced Energy Systems Division (Publication) AES, 1995-12-01) [Trabalho apresentado em evento]
Cogeneration system design deals with several parameters in the synthesis phase, where not only a thermal cycle must be indicated but the general arrangement, type, capacity and number of machines need to be defined. This ...
PERFORMANCE OF ARMA ALGORITHMS ON A TIME SERIES FROM A SIMPLE VIBRATING SYSTEM
(Structural Dynamics: Recent Advances - Proceedings of the 5th International Conference, Vols I and Ii, 1994-01-01) [Trabalho apresentado em evento]
A new high voltage polymer insulator for electrical distribution system from oil of Mamoma trees.
(IEEE 1995 Annual Report - Conference on Electrical Insulation and Dielectric Phenomena, 1995-01-01) [Trabalho apresentado em evento]
A tunable triode-MOSFET transconductor and its application to g(m)-C filters
(Iscas '99: Proceedings of the 1999 IEEE International Symposium on Circuits and Systems, Vol 2, 1999-01-01) [Trabalho apresentado em evento]
A linear, tunable CMOS transconductance stage is introduced. Drain voltage of the input transistor operating in triode region is settled by a regulation loop and a first-order linear relationship between g(m) and a de bias ...
The Liapunov exponent as a tool for exploring phase space
(Chaos In Gravitational N-body Systems, 1996-01-01) [Trabalho apresentado em evento]
We have used the Liapunov exponent to explore the phase space of a dynamical system. Considering the planar, circular restricted three-body problem for a mass ratio mu = 10(-3) (close to the Jupiter/Sun case), we have ...
Synchronous machines parameters identification using load rejection test data
(IEEE International Electric Machines and Drives Conference Record, IEMDC, 1997-01-01) [Trabalho apresentado em evento]
This work shows a computational methodology for the determination of synchronous machines parameters using load rejection test data. The quadrature axis parameters are obtained with a rejection under an arbitrary reference, ...
Influence of moisture absorption on mechanical behaviour of composites
(Euromat 97 - Proceedings of the 5th European Conference on Advanced Materials and Processes and Applications: Materials, Functionality & Design, Vol 2, 1997-01-01) [Trabalho apresentado em evento]
Because of their application that normally demands high mechanical strength combined with low weight, the fibre/matrix interface became an important parameter concerning structural life. The problem of moisture absorption ...
Orbital perturbations using geopotential coefficients up to high degree and order: Highly eccentric orbits
(Spaceflight Dynamics 1998, Vol 100, Part 1 and 2, 1998-01-01) [Trabalho apresentado em evento]
Several methods have been proposed for calculations of the eccentricity function for a high value of the eccentricity, however they cannot be used when the high degree and order coefficients of gravity fields are taken ...
Economic and technical feasibility study of a combined-cycle cogeneration system associated with cellulose plants
(American Society of Mechanical Engineers, International Gas Turbine Institute (Publication) IGTI, 1992-12-01) [Trabalho apresentado em evento]
In this paper, is presented an economical and technical feasibility study of a combined cycle cogeneration system proposed to be used in a pulp plant located in Brazil, where around 95% of country's pulp production is done ...
