This study includes comparison of various design parameters and evaluation of design strength based on the procedures predicted in the various codes of practices. A practical example has been assumed and calculation has been shown to evaluate their potentiality in understanding in predicting the potentiality of various procedures. The obtained results based on the methods varies widely, because of the different design considerations adopted by the different codes. As such, they have hardly considered the effect of confinement of the concrete due to the presence of longitudinal reinforcements as well as lateral ties. The study has attempted to throw light on critical review and their potentiality in assessing the strength of such concrete encased composite column under purely axial loads.展开更多

For the integrity of the DEMUX and the reliability of the internal operations, a data input buffer and a static latch were adopted. At the same time, the static latch enables the IC to work in a broader data rate range than the dynamic latch. Measurement results show that under a 1.8-V supply voltage, the DEMUX can operate reliably at any data rate in the range of 5-20 Gb/s. The chip size is 875×640μm^2 and the power consumption is 144 mW, in which the core circuit has a share of less than 28%.展开更多
