Metastructures, artificial arrangements of micro/macrostructures, possess unique properties and are significant interest in aerospace, stealth technology, various other applications. Recent studies have focused on quasi-zero stiffness metastructures, providing an outstanding vibration isolation capability. However, existing methods constrained to low preloads lack the consideration structural analysis, despite their intended use practical structures. This study introduces metastructures with...
This paper presents a novel intra deinterlacing algorithm (NID) based on content adaptive interpolation. The NID consists of three steps: pre-processing, classification, and There are also main interpolation methods in our proposed NID, i.e. modified edge-based line averaging (M-ELA), gradient directed (GDI), window matching method (WMM). Each shows different performances according to spatial local features. Therefore, we analyze the region feature using detection classify each missing pixel...
This paper presents an intra field de-interlacing algorithm for spatial edge preserving using the detection of accurate direction. Conventional algorithms determine direction at pixel or half level, so that they can be highly sensitive to noise and lead image degradation. In this paper, proposed first considers tendency in region, then candidate vectors (CDVs) are selected modified Sobel operation through tendency. Finally, CDVs adaptively applied interpolate lost region. Experimental...
The catalytic epoxidation of cyclohexene by iron(III) porphyrin complexes and H2O2 has been investigated in alcohol solvents to understand factors affecting the catalyst activity protic solvents. yields oxide FeIII/II reduction potentials iron were significantly affected solvents, there was a close correlation between product catalysts. role proposed control electronic nature that determines olefins H2O2. We have also demonstrated an electron-deficient complex can catalyze under conditions...
Integrating load-bearing and energy storage capabilities within a single material system, known as multifunctional structural batteries, holds immense promise for advancing technologies. These systems offer significant weight reduction enhanced safety, but their commercialization is hindered by challenges due to vast unexplored design spaces costly trial-and-error processes. In this work, we employ an experimentally validated computational framework accelerate the of carbon fiber (CF)-based...
Abstract A moving edge of a small mechanical structure, closely placed in front photodetector, can offer an easy means monitoring its motion via the optical knife-edge effect. Here, we present detailed analysis this nanomechanical detection scheme, which miniaturized device to be probed also serves as effective knife edge. Especially modulation generated from expected structure well corresponding sensitivity is considered by analytical and numerical modeling along with experimental...
This paper presents a block loss recovery technique for the image data corrupted by transmission losses through employment of fine directional interpolation (FDI). The proposed algorithm introduces spatial direction vector (SDV). SDVs are extracted from edge information neighboring data. Subsequently, adaptively applied to interpolate lost pixels on pixel-by-pixel basis. approach improves capability more reliably recover high-detailed contents in block. Experimental results demonstrate that...
The primary objectives of this paper are to describe the buckling patterns and determine squash load steel plate-concrete (SC) walls. major variables in study were width-thickness (B/t) ratio yield strength surface plates. Six SC walls tested, results include maximum strength, pattern plates, headed studs, behavior studs. Based on test results, effects B/t compressive also discussed. presents recommended effective length coefficients discusses varying plate, studs performance structures...
As the increasing number of Phasor Measurement Units (PMUs) are deployed, wide area protection in power systems has been gaining interest. In particular, fault detection, classification and estimation essential to reduce damage faults, even prevent catastrophic cascades failures. this paper, we present a scheme for using PMUs traveling wave theory. The purpose paper is formulate by calculating approximate location based on This research targeted at reliable operation transmission system...
Modern power supplies must provide reliable, high-quality power. Therefore, it is important that a transmission line fault be identified accurately, reliably and corrected as soon possible. A method for classifying type based on short time Fourier transform (STFT) provided in this paper. STFT means of signal processing which (FT) performed by setting window function with constant size. This transformation used to analyze transients the system. In order verify suggested algorithm, system...
