An Architecture for Computational Control of an Industrial Machine for Classifying Chestnuts
(Institute of Electrical and Electronics Engineers Inc., 2016)
Nowadays, the automation of industrial machines increase the productivity and efficiency of the mass production business. These machines are mainly composed of expensive electrical and mechanical modules to achieve companies ...
Análise do processo de furação profunda no aço SAE 4144M endurecido utilizando MQL e broca helicoidal revestida
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2014-03-27)
The drilling processes are widely used in the metalworking industry and involve high complexity when happen in depths more than five times the diameter. For these cases it is necessary to use special machines and tools, ...
Experimental and numerical study of heat transfer in hot machined workpiece using infrared radiation
(2014)
One of the greatest problems found in machining is related to the cutting tool wear. A way for increasing the tool life points out to the development of materials more resistant to wear, such as PCBN inserts. However, the ...
Automação da medição de forças e vibrações no torneamento com plataforma em LabView
(Universidade Tecnológica Federal do ParanáCuritibaBrasilTecnologia em Mecatrônica IndustrialUTFPR, 2017-11-16)
The machining processes, which consist of changing the dimensions of a part, are widely used in metallurgical and metalworking industries. Being one of the most equipment used for machining, with wide applicability and ...
Using metrics from complex networks to evaluate machine translation
(ELSEVIER SCIENCE BV, 2011)
Establishing metrics to assess machine translation (MT) systems automatically is now crucial owing to the widespread use of MT over the web. In this study we show that such evaluation can be done by modeling text as complex ...
Análise do planejamento e desenvolvimento de uma máquina expansora de tubos
(BrasilUFSMUFSM Cachoeira do Sul, 2022-02-15)
Machines and tools that assist in the mechanical conformation process are present in most metal-mechanical industries and aim to change the material's geometry through applied forces. Due to the need for machinery to expand ...
Data-driven identification of rotating machines using ARMA deterministic parameter evolution in the angle/time domain
(2020-09-01)
The functional-series angle-/time-varying autoregressive moving-average (AT-FS-ARMA) model was used to model and analyze vibration-based signals from internal combustion engines. This approach is derived from the formulation ...
Estimation of electrical machine speed using sensorless technology and neural networks
(2008-12-01)
The use of sensorless technologies is an increasing tendency on industrial drivers for electrical machines. The estimation of electrical and mechanical parameters involved with the electrical machine control is used very ...
