Abstract

The periodic measures of the stochastic delay reaction-diffusion lattice systems are investigated. Under a general condition, we prove the existence of periodic measures when the time-dependent terms of the system are periodic in time. Under further assumptions on the nonlinear terms, we show the set of all periodic measures of the perturbed system is weakly compact. Finally, we prove every limit point of a sequence of periodic measures of the stochastic delay system must be a periodic measure of the limiting system as the noise intensity or the time delay goes to zero.

Abstract

Objetivo: Identificar a intensidade sonora, por meio de decibéis (dB), no Centro de Material e Esterilização (CME) e orientar os colaboradoresquanto à importância dos protetores auriculares como equipamento de proteção individual (EPI). Método: Trata-se de um estudo descritivo, do tiporelato de experiência. Utilizou-se o aplicativo Sound Meter para medir a intensidade de ruído no CME. A pesquisa foi realizada em hospital de grandeporte de São Paulo, no período de uma semana, em 2018. Resultados: Os ruídos mais intensos foram mensurados no expurgo (93,0 dB), na área de preparo(92,3 dB), nas áreas de esterilização a baixa temperatura (91,6 dB) e a vapor (87,9 dB), diferentemente da percepção dos colaboradores. A conscientizaçãoda equipe deu-se por exposição dos resultados mensurados e discussão sobre importância do EPI. Conclusão: Verificaram-se ruídos mais intensosnas áreas de trabalho com maior número de maquinários, e houve divergência entre a intensidade do ruído mensurado e o percebido pelo profissional.Medidas educativas reflexivas são necessárias para a conscientização sobre a importância e adesão ao uso do EPI.

Abstract

The installation of fans and rooftop sprinklers in swine housing and management facilities can increase noise intensity and may impair workers' hearing health over longs periods of time; therefore, an assessment of the piglets’ stress during invasive practices was made. This study set out to evaluate the noise intensity emitted by environmental enrichment devices (fans and rooftop sprinklers) and by piglets restrained for body temperature assessments and its effect on animal welfare and on the hearing health of workers exposed to it for long periods. Twenty piglets ranging in age from five to twenty days were observed. The sow gestation area was divided into a cooled (fans and rooftop sprinklers) and uncooled area. Two decibel meters were used to measure noise intensity, one for the general noise in the facilities and the other for the piglets, with five-minute intervals between assessments. Digital thermometers were used to take the rectal temperature, and infrared thermometers were used to take the body surface temperature. Fixed-effects ANOVA for the housing environment and periods and multiple comparisons at a significance level of 5% were applied. The average dorsal temperature of the piglets was 36 °C ± 1.2 in the cooled area and 38.4 °C ± 0.5 in the uncooled area. In both periods, the average maximum noise intensity was over 100 decibels. In the afternoon, the maximum intensity was higher for the uncooled environment. The results indicate that neither the fans nor the rooftop sprinklers installed in the facilities nor the squealing piglets during restraint affect the noise intensity of the environment. However, the noise intensity demonstrates the piglets’ stress and the need for protective equipment to preserve the workers’ hearing health.

Abstract

Understanding the emergence of coordination behavior is of paramount importance in science and engineering. Environmental noise may have important impact on the coordination. In this brief, we consider a variation of the standard Cucker-Smale system in which individuals can not measure the states of others exactly. We present sufficient conditions on group size, noise intensity and communication rate to guarantee the almost surely exponential convergence toward flocking. We challenge the prevailing paradigm that noise suppressing the emergence of collective motion and report that noise may facilitate the emergence of ordered flocking behavior. We also find that group with high density can reach the ordered state more rapidly.

Abstract

This paper is an attempt to develop a mathematical model and simulation of noise radiation from refineries. Analysis of experimental results of noise radiation from the refining station was explored using Visual Basic Programming language. It was observed that simulated and experimental values to a large extent conform to the conceptualize pollutant migration pattern. Simulation result of the developed model shows that increase in distance from the refining point considerably reduced the radiated noise level. A new model for noise intensity radiating at the threshold of hearing (I0) is reported. [ABSTRACT FROM AUTHOR]

133. 有色噪声激励下双稳态电磁式振动能量捕获器动力学特性研究.

Author

Abstract

With the progress of MEMS technology, it is possible to power the sensor system by means of the electricity produced by the vibration energy harvester. The vibration energy harvesting technology based on environment vibration has become a hot topic for the study of nonlinear dynamics. The bistable electromagnetic vibration energy harvester with an auxiliary linear oscillator was studied. The dynamic equations under colored noise were established. The dynamic characteristics of the bistable vibration energy harvester excited by colored noise were studied through numeric simulation for varying parameters including the noise intensity, the mass ratio and the tuning ratio. The influencing law of the noise intensity, the mass ratio and the tuning ratio was obtained. The research results provide a theoretical basis for the further study of bistable electromagnetic vibration energy harvesters. [ABSTRACT FROM AUTHOR]

Abstract

This study empirically investigated the effects of noise type, noise intensity, and illumination intensity on reading performance. Three levels of noise types: factory noise, classical music, and pop with lyrics; three levels of noise intensity: 45 dBA, 65 dBA, and 85 dBA; and three levels of illumination intensity: 200 lx, 600 lx, and 1000 lx were tested. Results indicated that all three independent variables had significant effects on reading performance. Reading performance for classical music was significantly greater than that for pop with lyrics and factory noise. For noise intensity, 45 dBA resulted in the best reading performance, followed by 65 dBA, and 85 dBA. For illumination intensity, 600 lx resulted in the best reading performance, followed by 1000 lx and 200 lx. The interaction effects of noise type × illumination intensity were statistically significant. In conclusion, reading performance was best with classical music, low noise intensity, and normal illumination intensity conditions. [ABSTRACT FROM AUTHOR]

135. Reducing industrial noise by the use of damping alloys when manufacturing mining equipment parts.

Abstract

The existing experience of noise and vibration specialists has shown that the problem of noise reduction is very relevant, especially for the mining industry. Traditional methods of dealing with industrial noise are not effective enough. In solving this issue, it is advisable to reduce the noise level at the source of its occurrence through the use of metal alloys with enhanced dissipative properties. The article presents the results of experimental studies of developing steels with increased damping properties for manufacturing perforator parts: bit bodies and drill rods. In this article, the sound pressure level of alloys dependence on the type of heat treatment has been studied, and the optimal content of alloying elements has been established to ensure the development of the ferrite-pearlite structure. This structure is characterized by an increased dislocation density and is the reason for reducing the noise of the drill rod and the body of the perforator bit by 10-12 dB A. In addition, the article establishes the pattern of noise intensity at different frequency intervals for standard and developed alloys., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)
