Canopy Design and Fabrication for Reducing Noise Level Generated at Work Place without Affecting Equipment/Machine Performance
Abstract: Abstract Laws governing the safety and health of employed people exist in most countries of the world, the purpose being to create a suitable working environment and eliminate unsafe practices and processes. Work areas should be designed and laid out so that they are satisfactory both, from the environmental and safety points of view. In this connection, safety also implies that noise is kept at a level, which is not …

Design of Low Noise Transimpedance Amplifier using Multiple Feedback filter Topology
Abstract: This study presents the highly linear and low noise transimpedance amplifier (TIA) based on CMOS inverter as an amplifier within multiple feedback (MPFB) filter topology. Absence of complex analog circuitry and compatibility with widespread digital CMOS processes highlight this TIA topology asthe best choice in signal conditioning chains approaching analog-to-digital converters (ADCs). Special attention has been given to the TIA stability and compensation networks. Using dedicated low-dropout (LDO) regulator, the …

Matching Minutiae Fingerprint Q-Learning Approach for Detail Coordination: Identifiable Mark Point
Abstract: The use of fingerprints for high-precision recognition and identification of people is one of the most reliable biometric symbols because it is non-invasive. In this paper, we propose an innovative approach to detect details on low contrast resolution image quality of fingerprint images. Existing algorithms are not very susceptible to sound and image excellence due to the lack of level of intensity. We recommend a reliable route to find fingerprints …

Assessment of Acoustic Noise Generated from Machines in a Mechanical Workshop Using 1-Octave Band Frequency Analysis
Abstract: Acoustic noise is one of the prominent occupational health hazards, particularly in manufacturing and process industries. Prolonged exposure to loud noise can cause noise induced hearing loss of the exposed personnel. Limiting the exposure to noise intensity within its permissible exposure limit is adopted as one of the administrative control measures to reduce the risk of hearing loss. However, frequency specific assessment of occupational noise exposure is limited. Here, we …

Acoustic Characteristics of Person with Labial Cancer
Abstract: Oral cancer may arise as a primary lesion originating in any of the tissue in the mouth, by metastasis from a distant site of origin, or by extension from a neighboring anatomic structure, such as nasal cavity. Patients with tongue and lip cancer are particularly prone to speech and swallowing difficulties. The impact of labial cancer on speech relies on the area and size of growth. The present study was …

Disease: A Major Stumbling Block in the Growth of Aquaculture
Abstract: Aquaculture plays a crucial role in ensuring food security, fostering economic development, and providing recreational opportunities worldwide. However, the intensification of aquaculture practices has led to a surge in environmental challenges, including water pollution, soil acidification, eutrophication, chemical contamination, and the spread of diseases. Among these, diseases caused by bacteria, viruses, fungi, and parasites pose significant threats to the sustainability of global aquaculture. Despite the implementation of various diagnostic methods …

Safety of Foundation of Building
Abstract: The design of a building's foundation requires careful consideration of the load intensity applied from the structure above. To ensure stability and safety, the foundation depth must be sufficient to support the loads effectively. For residential buildings, where the loads are relatively lower, a foundation base size of 2.5 × 2.5 meters or 3 × 3 meters is typically adequate. In contrast, for structures with significantly higher loads, such as …
