Low-frequency audible noise generated by the magnetostriction effect inherent to the operation of power transformers has become a major drawback, especially in cases where the electrical substation is located in urban areas subject to strict environmental regulations that imposes sound pressure limits, differing for day and night periods. Such regulations apply a +5 dB penalty if a tonal component of noise is present, which is clearly the case of magnetostriction noise, typically concentrated at twice the industrial frequency (50 Hz or 60 Hz, depending on the country). The strategy used to eliminate the tonal characteristics, therefore contributing to establish compliance with the applicable regulation and to alleviate the discomfort it causes to the human ear, consisted in superimposing to the substation noise a masking sound synthesized from “sounds of nature” with suitable intensities, to flatten the noise spectrum while enhancing the soundscape. The masking system (heavy-duty speakers powered by a microprocessor platform) was validated at an already judicialized urban scenario. Measurement results confirmed that the masking solution was capable of flattening the tonal frequencies, whose beneficial effect yielded the cancellation of the public civil action filed by the neighbors. The proposed solution is ready to be replicated to other scenarios.

Read Range

In today’s era RFID system plays a key role in the field of asset tracking but its maximum read range or detectability may get degraded due to the challenges which are being provided by varying atmospheric conditions. So, to study the effect of these challenging atmospheric conditions, experimental investigation and statistical analysis of RFID system detectability has been carried out. Varying surrounding temperature, humidity and the presence of soil layer thickness in between RFID reader and tag and its five different grain sizes were considered as input parameters. All these observations were carried out for three different soils i.e. sandy soil, Silt and clay. Execution of test was carried out according to the MINITAB 17 tool. According to ANOVA analysis as well as from interaction plot it was found that soil layer thickness have more impact on RFID system read range and R2 value was found to be 96.91%, 99.64% and 99.78% for RRSS, RRS and RRC respectively. Composite desirability of optimization was found to be 0.8425. Optimum values of process parameters Temperature, Soil Layer Thickness, Relative Humidity and Soil Grain Size were found to be 303.3°K, 2.5 cm, 40.1 %, 1.92 mm respectively. Best values of responses were found to be 10.94 cm for (Read Range in presence of Clay); 11.02 cm (Read Range in presence of Silt) and 10.97 cm (Read Range in presence of Sandy Soil).

Abstract Animal facilities are increasing in size while the availability of skilled workers is decreasing, making it difficult for farm laborers to ensure the health and well-being of all animals under their care. Systems that apply technology to the animal system can not only improve animal care, but also give researchers and engineers an understanding of the animal’s use of the facilities. This insight can lead to new engineering designs. In addition, these systems create an individual data stream that can be used to create unique animal phenotypes. Radio Frequency Identification is used in many different applications including store inventory, timing of races, attendee tracking, toll roads, and animal identification. There are different types of RFID systems each has unique attributes that create advantages or challenges to different situations. Both active and passive systems will be discussed, along with the three common passive frequency ranges: low frequency, high frequency, and ultra-high frequency. The advantages and disadvantages to each of the frequency ranges determine which type of system should be used for a given application. Typical uses of RFID tags include animal population tracking and animal data base monitoring. RFID systems have also been used for monitoring of animal activities such as eating and drinking behavior. Placement of the antennae and strength of the antenna field is critical to behavior monitoring. The behavior data streams have been used to determine potential illness, heat tolerance, and potential social interactions.
