Comparative analysis of synchronization algorithms based on PLL, RDFT and Kalman Filter
(2007-12-01)
This paper discusses the main characteristics and presents a comparative analysis of three synchronization algorithms based respectively, on a Phase-Locked Loop, a Kalman Filter and a Discrete Fourier Transform. It will ...
Design of a tool for the visualization of historical data
(2014-11-12)
Abstract. In the sciences the combination of different types of analysis, textual and visual, contributes to the legibility of the results of the research. Techniques such as data visualization and information graphics ...
A single-phase single-stage buck-boost inverter intended for low power alternative energy conversion systems: Analysis, design and experimentation
(2012-12-01)
This paper presents the operational analysis of the single-phase integrated buck-boost inverter. This topology is able to convert the DC input voltage into AC voltage with a high static gain, low harmonic content and ...
Setting the preheating process of electronic ballasts for hot-cathode fluorescent lamps, considering the Rh/Rc ratio
(2006-12-01)
This paper presents a new model for the representation of the electrodes filaments of fluorescent lamps, during their preheating, and an analysis capable to guide the design of the preheating process in electronic ballasts. ...
Design and development of a low-cost prosthesis directed to the activity with a gasoline brush cutter: A case study
(2017-01-01)
In Brazil, the rate of people with disabilities resulting from amputation is relevant. The distribution of high-tech prostheses only meets a small portion of the population. On the other hand it is known that most of the ...
Product and process development using the lean thinking principles in an automotive industry
(SAESão Paulo, 2014-10-30)
The competition among automotive industries increases each year worldwide. Traditional industries as well as traditional markets end up becoming the target for expansion of new global industries. It can be stated that ...
Computational tool to support design of DAC Converter model AD7528 with the object code in XML
(2012-12-01)
Based on literature review, electronic systems design employ largely top-down methodology. The top-down methodology is vital for success in the synthesis and implementation of electronic systems. In this context, this paper ...
GUIDELINES FOR THE ALIGNMENT OF THE INTEGRATED MANAGEMENT SYSTEM WITH THE BUSINESS STRATEGY IN INDUSTRIAL COMPANIES
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2018-01-01)
With today's globalized and increasingly competitive organizational landscape, organizations need strategy to survive in the midst of excessive competition. In order to save efforts and resources, companies have started ...
Swarm control designs applied to a micro-electro-mechanical gyroscope system (MEMS)
(2010-12-01)
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 ...
Development of an instrumentation system embedded on FPGA for real time measurement of mechanical vibrations in rotating machinery
(2012-11-23)
The real-time monitoring of events in an industrial plant is vital, to monitor the actual conditions of operation of the machinery responsible for the manufacturing process. A predictive maintenance program includes condition ...
