Relative Importance for Lincoln’s Sparrow (Melospiza lincolnii) Occupancy of Vegetation Type versus Noise Caused by Industrial Development
(2022)
Anthropogenic noise can create an acoustic environment detrimental for animals that communicate using acoustic signals. Currently, most studies of noise and wildlife come from traffic noise in cities. Less is known about ...
A chromatic technique for structural damage detection under noise effects based on impedance measurements
(2019-05-31)
Structural health monitoring (SHM) based on electromechanical impedance (EMI) measurements has been extensively studied in recent years and stands out as an effective damage detection approach. The EMI method commonly uses ...
Estudo do ruído em transformadores de distribuição da classe 15kV em função da indução do núcleo
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2015-06-10)
This work aims to study the main sources of noise in the distribution transformer of 15kV class, the processes required for carrying out the tests in the manufacturer's laboratory as set by the NBR 7277/2013. Develop an ...
Análise de ruído na praça de alimentação de shopping centers
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEspecialização em Engenharia do TrabalhoUTFPR, 2017-05-31)
Noise is an environmental hazard classified as physical and that is present in work environments. The agent has great potential for harm to the health of the worker, reaching the human ear that is a sensitive organ. Unlike ...
Amplitude distortion of measured leak noise signals caused by instrumentation: Effects on leak detection in water pipes using the cross-correlation method
(2019-11-24)
A common way to detect and locate leaks in buried water pipes is to use leak noise correlators. Vibration or acoustic signals are measured on or in the pipe using sensors placed either side of the leak, and the difference ...
Realistic model of a solid-substrate fermentation packed-bed pilot bioreactor
(ELSEVIER SCI LTD, 2007)
For any given large-scale solid substrate fermentation (SSF) bioreactor, to assess how well a control system will work in practice requires the most realistic model possible. This model needs to account fully for complicated ...
Análise do ruído e intervenção fonoaudiológica em ambiente escolar: rede privada e pública de ensino regular
(CEFAC Saúde e Educação, 2014-03-01)
Purpose : the aim of this study is to measure noise levels during the school year in two classrooms in a grade of elementary school, a private schools one and a public school another, in both case frequented by deaf students ...
Medição do nível de potência sonora em ambientes reverberantes
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2013-04-25)
The measure of level of sound power is done using the standards ISO 3740 till ISO 3747. These standards show correction factors K 1A e K2A that compansate the sound absorption and the background noise of the room. In this ...
