Path Loss Modeling of Wireless Signals in Underground Tunnels by Yaning Li, Baoguo Yu, Lu Huang

“…In this paper, a hybrid model describing the propagation attenuation of wireless signals in underground tunnels is proposed, which divides the propagation channel into three subdomains according to the length of the tunnel, namely, the region of the free space propagation model, the region of the multimode propagation described by the ray tracing method, and the region of the improved waveguide model by adding the influences of tunnel roughness, tunnel inclination, and metal pipes. …”

Slip Effects on Peristaltic Transport of a Particle-Fluid Suspension in a Planar Channel by Mohammed H. Kamel, Islam M. Eldesoky, Bilal M. Maher, Ramzy M. Abumandour

“…It is found that the critical reflux pressure is lower for the particle-fluid suspension than for the particle-free fluid and is affected by slip condition. A motivation of the present analysis has been the hope that such theory of two-phase flow process under slip condition is very useful in understanding the role of peristaltic muscular contraction in transporting biofluid behaving like a particle-fluid mixture. …”

Sustainable Highway Design: Disentangling the Effects of Geometric-Related and Traffic-Related Factors on Urban Highway Traffic Emissions by Xue Bing, Quanlun Wei, Jian Lu, Chaoyang Li, Yi Zhang

“…The geometric-related factors are lane width, number of vehicle lanes, and intersection lane configuration, and the traffic-related factor is free-flow speed. The results indicated that (1) widening the lane width may cause the increase of CO emissions, (2) increasing the number of vehicle lanes may result in the decrease of all three emissions, (3) intersection lane configuration has significant influence on traffic emissions, and (4) the average speed of 23-24 mph is associated with the lowest traffic emissions. …”

Seropositivity for Bovine Viral Diarrhea and Enzootic Bovine Leukemia viruses in Blanco Orejinegro cattle in Colombia and infection associated-factors by A. Saldarriaga-Saldarriaga, M. Londoño-Gil, L. G. González-Herrera, J. C. Rincón-Flórez, A. López-Herrera

“…For BVD, seropositivity obtained was 50,6%, and the factors associated with seropositivity identified were having had a history of the disease in the herd, and using semen from bulls that are not known to be free for the infection. We suggest establishing control measures considering the factors associated with each viral infection to limit their expansion in the BON cattle production systems of Colombia.…”
