Parametric Study of Factors Affecting Sound Absorption Characteristics of Acoustical Materials,everberation chambers. The various factors affecting the sound absorption characteristics such as air-gap, thickness, bulk density, porosity, tortuosity and air flow resistivity have been discussed based on the previous studies. The study also reports some of the recently developed acoustical sound

Variation of Atmospheric Boundary Layer Height and Application of Forward Selection Technique durinrs) and climatic conditions. Air quality, ABL height, and Ventilation Coefficient (VC) have all been studied over the past four years as a result of firecracker use. By employing a forward selection technique, we have determined the most important factors that influence the ABL‘s height. The primary

Separation of Weak Signals from White Noises Using Python-Based Software,on of such signals is important for further studies. However, these signals are often mixed with high-frequency noises. These noises have very high-frequency, zero expectation value and zero average value. Various fields of control theory like, convolution time domain, frequency domain, and time dom

Ozone Formation Potential of Volatile Organic Compounds During November 2021 at an Urban Site of Deto understand the ozone formation potential (OFP) of different VOCs at an urban site of Delhi in November 2021. Ambient air samples were collected for VOC analysis using GC-FID. The total concentration of VOCs was (80.47 ± 38.77) ppbv. Out of 22 species of VOCs, n-butane has the highest monthly aver

Calibration and Analysis of Precision Capacitance Bridge and LCR Meter for Dissipation Factor Measuidge. The dissipation factor is measured in the range of 0.1 to 0.0001 with uncertainties in the range of 0.1% to 11%. The precision capacitance bridge and LCR meter are calibrated for dissipation factor at 1 kHz. The calibration results are compared and discussed in the presented work. It is observ
