SmartApprox: learning-based configuration of approximate memories for energy-efficient execution
(Campo MouraoBrasil, 2022-04)
Approximate memories reduce power and increase energy efficiency, at the expense of errors in stored data. These errors may be tolerated, up to a point, by many applications with negligible impact on the quality of results. ...
Chaveador wireless para teclado e mouse
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia EletrônicaUTFPR, 2022-06-13)
Working from home has been a trend in recent years and has gained a monumental scale due to the coronavirus pandemic that started in 2020, when about 11 percent of Brazilians workers worked in this modality. Along with ...
A low-voltage triode-MOSFET four-quadrant multiplier with optimized current-efficiency
(2001-01-01)
A low-voltage, low-power four-quadrant analog multiplier with optimized current-efficiency is presented. Its core corresponds to a pseudodifferential cascode, gain-boosting triode-transconductor. According to a low-voltage ...
Software para desenvolvimento de transformadores para equipamentos de eletrocirurgia
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2012-09-20)
This work describes a software that performs calculation and gives some tips about building and measuring transformers parameters up to 500 W till a few megahertz. The software emulates 3 models: the classical T model for ...
Ferramenta de compilação para a geração de código para um runtime de offloading automático
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de ComputaçãoCiência da ComputaçãoUTFPR, 2019-06-27)
Heterogeneous computing is an area in computer science that has become of great interest both comercially and academically. This area encompasses our understanding of computer nodes formed by both accelerating devices, ...
A feasibility study of a complete low-cost consumer-grade brain-computer interface system
(Elsevier Ltd, 2020-03)
Brain-computer interfaces (BCIs) are technologies that provide the user with an alternative way of communication. A BCI measures brain activity (e.g. EEG) and converts it into output commands. Motor imagery (MI), the mental ...
Nonsignaling Deterministic Models for Nonlocal Correlations have to be Uncomputable
(American Physical Society, 2017-03)
Quantum mechanics postulates random outcomes. However, a model making the same output predictions but in a deterministic manner would be, in principle, experimentally indistinguishable from quantum theory. In this work we ...
