Study on size effect of RC and rehabilitated exterior beam-column connections under cyclic loading

Abstract: Beam-column connection is one of the vital structural parts, whose behaviour during earthquake is very critical. An experimental programme was undertaken by considering three types of exterior RC beam-column connections with three different sizes of geometrically similar specimens in each type. The specimens were tested under displacement-controlled cyclic loading. Depending on the level of damages, rehabilitation strategies were applied appropriately. The studies were repeated for all the rehabilitated specimens and observed that the rehabilitated specimens could successfully restore their load-carrying capacity. Further, the experimental results from specimens of different sizes revealed the existence of a significant size effect, which could approximately be described by the size effect law previously proposed by Bažant. The size effect was further observed to be more prominent with the increase in brittleness of specimens. Energy dissipation per unit volume (eN) of the D-region was also correlated wit...

Improved Decomposition of Multiple-Control Ternary Toffoli Gates Using Muthukrishnan-Stroud Quantum Gates

Abstract: In conventional binary reversible circuit synthesis, reversible gates are decomposed into quantum gates using some standard quantum gate library In recent years there has been increased attention in synthesis using ternary reversible gates since it leads to a reduction in the number of lines However, very few works exist that address the problem of decomposing ternary reversible gates based on some ternary quantum gate library Most of these works use Muthukrishnan-Stroud (M-S) gates for decomposition of ternary Toffoli gate, and they use a naive approach that requires an exponential (in number of control lines) number of M-S gates Also the number of ancilla lines required is (\(c-1\)), where c is the number of control lines The present paper proposes a method for decomposing ternary Toffoli gates to M-S gates that requires less number of ancilla lines, and also requires a number of M-S gates that is linear in c A template-based post-decomposition optimization step has also been used to further reduce the number of M-S gates required Decomposition results for up to 16 control lines have been presented

Design of a compact triple-band metamaterial absorber with wide angle of incidence using connected resonator topology

Abstract: A compact triple band metamaterial absorber is presented in this paper. The triple band absorbance is achieved by combining a meander line loaded rectangular close ring resonator with an electric field driven LC resonator within a single unit cell. A more compact unit cell having a size reduction of 14.47% and triple band absorption has been realized as an advantage over close ring metamaterial absorber. The artificially engineered structure has triple band absorbance with one band laying in C-band and another two in Ku and K band respectively. This triple band design can be used for stealth technology such as the C-band airborne radar and battlefield applications. Moreover, the absorber can perform well over a wide angle of incidence.

A Competition between Dissociation Pathway and Energy Transfer Pathway: Unimolecular Dissociation of a Benzene-Hexafluorobenzene Complex in Nitrogen Bath.

Abstract: The unimolecular dissociation of a benzene-hexafluorobenzene complex at 1000, 1500, and 2000 K is studied inside a bath of 1000 N2 molecules kept at 300 K using chemical dynamics simulation. Three bath densities of 20, 324, and 750 kg/m3 are considered. The dissociation dynamics of the complex at a 20 kg/m3 bath density is found to be similar to that in the gas phase, whereas the dynamics is drastically different at higher bath densities. The microcanonical/canonical dissociation rate constants for the three bath densities are calculated and fitted to the Arrhenius equation. The activation energies are found to be similar to the gas-phase one. However, the pre-exponential factor is lower and decreases with the increase in bath density. The vibrational degree of freedom of the complex more effectively participates in the collisional energy transfer to the N2 bath, whereas the translational and rotational degrees of freedom of N2 receive the transferred energy. The energy transfer efficiency increases with the increase in bath density. The time scale of the energy transfer pathway is more than that of the dissociation pathway, and negligible direct dissociation of the complex is observed from the simulation at the highest bath density.
