Technological Progress in Thin Wall Austempered Ductile Iron: From Manufacturing to Operation
Abstract: Nowadays, aluminum is used more often than cast iron in the production of cast parts due to the desire to reduce vehicle weight. Theoretically, austempered ductile iron can be used in high strength, light weight parts because thin wall austempered ductile iron (TWADI) components can be produced with strength-to-density ratios that are comparable to those of cast aluminum. Thus, advancements in the technology of thin wall austempered ductile iron are …

Analysis of Vibrational Induced Structure Considering Rail and Seismic Load Using ETABS
Abstract: In the past, buildings next to railroad tracks were not taken into account when designing them, which resulted in catastrophic damage to the buildings as well as fatalities. For these structures to be designed safely, the vibrational loading must diminish. This study's case study is the Rani Kamlapati railway station in Bhopal, which was renovated by the Bansal Group and is the nation's first private railroad station. They suggested building …

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 …
