The steep growth of digital-content consumption and increasing reliance on wireless networks has resulted in emerging standards such as IEEE 802.11ac. By employing spatial diversity, Multi-user MIMO high-density modulation (up to 256-QAM), 802.11ac radios can provide significantly increased throughput, link robustness, range while maintaining backward-compatibilities with existing 802.11a/n WLAN [1]. However, wide signal bandwidth lead significant challenges all aspects RF transceiver...
Abstract Studies have shown that random vibration theory (RVT) site‐response analysis predicts site amplification at the natural frequencies are systematically larger than results obtained from time series (TS) using a suite of input TS. A critical part RVT approach is peak factor, defined as ratio to root mean square (rms) value signal. This study investigates influence different factor models on estimated by analysis. It use Vanmarcke (1975) model rather Cartwright and Longuet‐Higgins...
In this paper, the metal‐assisted chemical etching (MACE) method is presented along with advantages of using method. Large areas and a combination large narrow patterning are successfully produced by metal meshes for MACE. Moreover, in order to exemplify microfabrication technique, authors demonstrate fabrications different microelectromechanical systems (MEMS) devices; from simple structure (micro‐cantilever) complex (capacitive silicon resonator). Micro‐cantilever beam resonant frequency...
Criteria are proposed for determining the stiffness and strength demands seismic design of pin-supported walls in low- medium-rise reinforced-concrete moment frames. A plasticity ratio a global introduced to evaluate effect (PS walls) mobilizing capacity frame. Incremental dynamic analyses 4-, 8-, 12-story prototype PS wall-moment frames various ratios show that constant two can generally ensure formation plastic mechanism no matter if frame is strong column-weak beam one or not.

Traditional ground-motion models (GMMs) are used to compute pseudo-spectral acceleration (PSA) from future earthquakes and generally developed by regression of PSA using a physics-based functional form. is relatively simple metric that correlates well with the response several engineering systems commonly in evaluations; however, characteristics calculation make application scaling factors dependent on frequency content input motion, complicating development adaptability GMMs. By comparison,...
ABSTRACT The displacement response of a building structure to earthquake excitations is crucial for assessing its seismic damage, which usually accompanied by structural nonlinear behavior. This study proposes an efficient method quickly estimating the responses seismically damaged buildings. By designing set sparsely and uniformly distributed samples in multi‐dimensional parameter space, this traverses all these find best parameters parametric numerical model that minimizes error between...

Abstract We used coffee husks as an additive during the smelting of industrial silicon. The influence different carbon material mixtures on efficiency a silicon furnace was evaluated using cover fires index, excess and exergy index. results showed that after adding husks, number fires(Gh) stable, average time(Tg) ranged from 6 to 11 min, interval fires(T G ) increased. When semi-coke without index 1.29, non-recovery 0.342, recovery 0.435. After decreased 1.28, increased 0.343 0.437. were...

In a conventional base isolation system, minimizing the seismic responses of superstructure is always at cost increasing isolator's response. The semi-active control isolator has been considered an effective solution to such dilemma. It tunes real-time properties according preset rules further reduce superstructure's without that or vice versa. However, number ground motion records used design and validate controller, i.e., rules, in existing studies usually very small therefore suspectable...
Abstract Bulk multi-pass cell (MPC) is an effective technique used for spectral broadening and temporal compression in the fields of ultrafast optics. In actual experiment, due to mode-mismatching, beam profile changes at each pass transmitting through medium, which will damage optical elements has a negative impact on nonlinear effects. this paper, based symmetry configuration MPC ABCD transfer matrix, we propose matrix model propagation adjusted optimization method input beam. To verify...
