Managing Pavement Settlement Risk: Impact of Waterlogging and Soil Conditions
Abstract: In the context of road infrastructure, the occurrence of waterlogging due to rainfall can have significant repercussions. Rainwater often infiltrates the road surface and, depending on factors such as the depth of the foundation and the extent of penetration into the ground, can lead to the soil beneath the road becoming either moist or saturated. This, in turn, can result in a reduction of the soil's bearing capacity. When vehicles …

Design and Analysis of A Terahertz Microstrip Antenna
Abstract: Terahertz radiation is in the electromagnetic spectrum. Terahertz radiation is used for a variety of purposes since it is non-ionizing and may move in a straight line. It has some similarities with microwaves, in that terahertz radiation can penetrate non-conducting materials, but it shows less depth of penetration than microwaves. Compared to millimeter waves the capacity of Terahertz waves is large enough and possesses high data transmission rates. Terahertz radiation …
