This paper presents a high-efficiency 165-GHz ON–OFF keying transmitter in a 65-nm CMOS technology with the record efficiency to the best of our knowledge. This is due to the proposed holistic design and optimization procedure, which links all the performance and figure-of-merits to the device sizes, including both actives and passives. This transmitter includes a high-efficiency transformer-based...
The practical calculation method for the residual strength of reinforced concrete columns with +-shaped cross section after exposure to ISO834 standard fire is investigated. Using a numerical program CAFIRE, the influence of several parameters, such as exposure times, effective lengths, sectional thicknesses, ratios of sectional height to sectional thickness, load eccentricity ratios, reinforcement...
