We have observed that the size and shape of the conducting reflector of CPW-fed slot antennas using loading metallic strips and a widened tuning stub have significant impact on the antenna impedance matching and radiation pattern. By shaping the reflecting conductor, noticeable enhancements in both radiation pattern which provides uni-directional all frequency operating band and characteristic ...

Loose sand samples under different complex shear paths and directions of consolidation stress were simulated using bi-directional simple DEM models. Liquefaction characteristics corresponding meso-mechanisms analyzed, the following conclusions drawn. Bi-directional cyclic accelerated drop in vertical stress, especially first last cycles. Compared to uni-directional tests, contact force between ...

We develop a Recurrent Neural Network (RNN) Language Model to extract sentences from Yelp Review Data for the purpose of automatic summarization. We compare these extracted sentences against user-generated tips in the Yelp Academic Dataset using ROUGE and BLEU metrics for summarization evaluation. The performance of a uni-directional RNN is compared against word-vector averaging.

The smoke and air flow through a horizontal opening was investigated using model-scale room equipped with on the ceiling. A layer created under ceiling small gas burner. pressure difference across changed by controlling supply to exhaust from space above opening. Smoke patterns were either downward uni-directional of air, bi-directional or upward. By changing opening, critical differences cause...

The purpose of this investigation is to examine the viability of using the sheet metal for forming applications. Forming limit diagram (FLD) composed of negative and positive minor strain with respect to major strain which occurs at directional zero strain with the critical thickness of sheet metal. The negative minor strain region of FLD is predicted by localized necking. However there is no d...

The growth of scleractinian corals is strongly influenced by the effect of water motion. Corals are known to have a high level of phenotypic variation and exhibit a diverse range of growth forms, which often contain a high level of geometric complexity. Due to their complex shape, simulation models represent an important option to complement experimental studies of growth and flow. In this work...

Despite various work which aimed to identify the phonetic and structural underpinning of tone sandhi directionality, underlying mechanism that governs remains unknown. We note two widely discussed properties sandhi, their grounds correspond types cognitive biases investigated in segmental phonology, namely substantive bias respectively. This study examines simplicity naturalness patterns across...

This article is concerned with relating the stability of a population, as defined by the rate of decay of fluctuations induced by demographic stochasticity, with its heterogeneity in age-specific birth and death rates. We invoke the theory of large deviations to establish a fluctuation theorem: The demographic stability of a population is positively correlated with evolutionary entropy, a measu...

The nerve growth cone is bi-directionally attracted and repelled by the same cue molecules depending on the situations, while other non-neural chemotactic cells usually show uni-directional attraction or repulsion toward their specific cue molecules. However, how the growth cone differs from other non-neural cells remains unclear. Toward this question, we developed a theory for describing chemo...

The design of a platform for bi-directional musical performance using modern WAN networks poses several challenges that are different from related applications, e.g., synchronous LAN studio systems or uni-directional WAN streaming. The need to minimize as much as possible audio latency and also maximize audio quality requires specific strategies which are informed, in part, by musical decisions...
