Wastewater-based epidemiology has been used for monitoring human activities and waterborne pathogens.Although wastewaters can also be used for tracking SARS-CoV-2 at the population level, the reliability of this approach remains to be established, especially for early warning of outbreaks.We collected 377 samples from different treatment plants pro

The high-speed-train pantograph is a complex structure that consists of different rod-shaped and rectangular surfaces.Flow phenomena around the pantograph are complicated and can cause a large proportion of aerodynamic noise, which is one of the main aerodynamic noise sources of a high-speed train.Therefore, better understanding of aerodynamic nois

The Development in technology has brought about a common norm of communicating and interacting with appliances remotely using portable devices like laptops and smartphones that have Internet connections.This is possible with the use of the Internet of Things, popularly referred to as IoT.This paper presents a system by which classroom held interact

This paper explores the dynamics of $ 2 $D spatiotemporal discrete motovox scooter parts systems, focusing on the stability and bifurcations of periodic solutions, particularly $ 3 $-cycles.After introducing the concept of a third-order cycle, we discuss both numerical and analytical techniques used to analyze these cycles, defining four types of $
