Mercury (Hg) enrichment and elevated ratios of Hg to total organic carbon (Hg/TOC) in sedimentary rocks have often been linked volcanism from large igneous provinces (LIPs). Primary TOC contents sediments can be altered by secondary processes like extreme weathering. These effects must evaluated before tying anomalies weathered directly LIP events. However, the incipient weathering on Hg/TOC are not known. In this study, we elucidate behavior during investigating visually pristine black...
Spaceborne radar remote sensing of the earth system is essential to study natural and man-made changes in ecosystem, water energy cycles, weather air quality, sea level, surface dynamics. A major challenge with current approaches lack broad spectrum tunability due narrow band microwave electronics, that limit systems specific science variable retrievals. This results a significant limitation studying dynamic coupled processes such as subsurface hydrology from single compact instrument, where...
This paper proposes a system design for automation in multi-agent-based manufacturing systems to conduct given complex task automatically by controlling multiple robotic manipulators systematic manner. To this end, the proposed is designed with three-module configurations: environmental perception, planning, and motion planning. The perception module utilizes vision sensor recognize all objects placed on workspace extract their unique ID, size, pose. planning divides into primitive skill...
Today, a paradigm in the manufacturing industry has been shifted from mass production to small and custom production. To adapt today's industrial expectations, this paper presents position-based visual servoing of multiple robotic manipulators. The presented consists two modules: task planning motion planning. module manipulates each arm not collide with other by distributing them systematic manner. employs MoveIt framework solve inverse kinematics for so that it moves end-effector's pose...

Condition-based monitoring has emerged as one of the important tools in power plants to continuously supply high-quality power. This paper, we describe a mechanism for high-voltage electrical equipment using thermal imaging with aim detecting faults system advance and reducing losses.
Ammonite provincialism makes it difficult to link the Boreal and Tethyan realms during Late Jurassic Early Cretaceous time. Absolute ages through radiometric dating offer new age information that is independent complementary relative based on biostratigraphy. In this study, we report seven Re-Os for black shales from Agardhfjellet Formation, Svalbard. We also pyrolysis results, carbon sulfur stable isotopic data, initial 187Os/188Os ratios evaluate paleoenvironment organic-rich shale...
본 논문에서는 좌굴방지 가새 (BRBF)가 설치된 중저층 철골조 구조물의 초과강도계수를 평가하였다. 해석 모델의 설계변수로는 건물의 층 수, 경간의 길이, 가새의 항복강도, 지진하중의 크기, 반응수정계수 등 다양하게 설정하였다. 초과강도계수는 ATC-19에서 제시하고 있는 방법에 따라 정적 비탄성해석을 이용하여 산정하였다. 해석결과에 따르면 연구에서 구한 BRBF의 AISC/SEAOC에서 BRBF에 관하여 제시한 초과강도계수 값보다 전체적으로 크게 나타났다. In this study the overstrength factors of medium to low-rise bucking restrained braced frames (BRBF) were evaluated. Various design variables, such as number stories, span length, yield strength brace, level earthquake load, and response...
<p>Perceived mercury (Hg) enrichments and elevated ratios of Hg to total organic carbon (Hg/TOC) in sedimentary rocks have often been linked volcanism from large igneous provinces (LIPs) mass extinctions, prompting the hypothesis that concentrations are a proxy for intense LIPs.  However, primary TOC contents can be altered by secondary processes, example, <em>intense</em> weathering [1].  Before endorsing cause-and-effect...
