Design of New Single-Electron Reaction-Diffusion Circuit with Ability to Generate and Control Plane Waves
Get PDFWe propose a new single-electron (SE) reaction-diffusion (RD) circuit that can express traveling plane waves. While SE circuits have advantages such as nonlinearity and stochastic behavior, a suitable information processing method has not yet been established for them. Thus, we focus on the behavior of a photo-responsive (PR) Belousov-Zhabotinsky (BZ) reaction, one of RD systems, to develop a suitable information processing method. Reportedly, the PR-BZ reaction can generate plane waves, and the waves can be used to represent logic gates. Here, we designed the new SE-RD circuit that can generate the desired plane waves. In simulation results, we found our circuit can operate as desired. We believe this circuit can be used to construct a logic gate device as same as the PR-BZ reaction.2023 Silicon Nanoelectronics Workshop (SNW) 11-12 June 202
Bloomier Filters on 3-Hypergraphs
Get PDFA Bloom filter, originally proposed by Bloom in 1970, is a probabilistic data structure used to determine membership in a set with enduring false positive errors. Due to the trade-off between space efficiency and the probability of false positive errors, Bloom filters have found numerous applications in network systems and various fields of information sciences. Chazelle et al. [6] extended this concept to a more versatile data structure known as the Bloomier filter, capable of encoding arbitrary functions. With Bloomier filters, it becomes possible to associate values with specific elements of the domain, enabling more generalized use. In this paper, we propose a variant of Charles and Chellapilla’s scheme [5] that utilizes minimal perfect hashings. Specifically, instead of using bipartite random graphs like existing Bloomier filters, we present a space-efficient Bloomier filter with faster creation time based on an analysis of 3-hypergraphs, in comparison to previous results.Information Security Applications 24th International Conference, WISA 2023, Jeju Island, South Korea, August 23–25, 2023
Influence of Concrete Material Property on Failure Mode of Steel–Concrete Connection Under Monotonic Load
Get PDFThis study aimed to investigate the structural behavior of the steel–concrete connection under monotonic loading, utilizing different types of concrete. Both experiment and finite element analysis under the same conditions were performed. First, three specimens with embedded steel anchors were cast using three different concrete materials, which were ordinary Portland cement concrete, geopolymer concrete, and prepacked concrete. The pull-out test was performed to observe the failure modes of each specimen occurring in the form of cracking, crushing, and other forms of concrete failure. The load–displacement relationship of the structures was measured so that the ultimate capacity could be determined. Second, finite element analysis using finite element code, COM3D employed the same experimental conditions and was carried out to observe the nonlinear behavior of structural concrete and verify the pull-out test results. In both the experiment and analysis, the highest ultimate tensile capacity was obtained from ordinary Portland cement concrete, followed by prepacked concrete. The geopolymer concrete showed the lowest ultimate capacity. Load–displacement relationship obtained from the experiment and analysis showed a similar trend. The difference in stiffness attributed to the interface between steel and each concrete type could be observed. In the experiment, the ordinary Portland cement concrete and prepacked concrete exhibited shear failure behavior; however, geopolymer concrete showed splitting tensile failure. On the other hand, the analysis results showed splitting tensile failure in all cases.World Conference on Floating Solutions
