Plastics are widely used in various industries because of their light weight, low cost, and high durability. The mass production consumption plastics have led to a rapid increase plastic waste problem, necessitating the development effective recycling technologies. chemical has emerged as promising strategy address these challenges, enabling conversion into high-purity monomers or oils, even from contaminated mixed feedstock. This review focuses on catalysts for South Korea, which one...
The present study concerns a feasibility for applying principal component analysis to ship dynamics in maneuver. Using the four degrees of freedom standard modular model maneuver simulations large angle zigzag tests with rudder deflection variations are conducted. datasets motion, hydrodynamic force, and moment during acquired identify modes. covariance matrix obtained variables shows strong linear correlation between moment, except surge force. Four eigenvectors selected as modes dynamics....
Sequential recommenders have made great strides in capturing a user's preferences. Nevertheless, the cold-start recommendation remains fundamental challenge as they typically involve limited user-item interactions for personalization. Recently, gradient-based meta-learning approaches emerged sequential field due to their fast adaptation and easy-to-integrate abilities. The algorithms formulate few-shot learning problem, where each user is represented task be adapted. While generally assume...
In asymmetric memory systems, the pull-up and pull-down data from channel can have different amounts of inter-symbol interference (ISI), so they cannot be fully corrected by an equalizer which uses a single tap weight. We introduce receiver-side single-ended 1-tap decision-feedback (DFE) with weight selection multiplexer, allows application to each direction value transition. Implemented in 55-nm CMOS technology, our DFE compensated for ISI 10.4-Gb/s signal insertion loss -8.3 dB, leading...
Teeth localization, segmentation, and labeling from intra-oral 3D scans are essential tasks in modern dentistry to enhance dental diagnostics, treatment planning, population-based studies on oral health. However, developing automated algorithms for teeth analysis presents significant challenges due variations anatomy, imaging protocols, limited availability of publicly accessible data. To address these challenges, the 3DTeethSeg'22 challenge was organized conjunction with International...
Despite extensive research on plain-fin heat sinks with impinging flow, there have been few studies that evaluate the impact of flow nonuniformity their performance, in spite fact at inlet is a key factor affecting sink performance. This study developed novel methodology to quantitatively assess by combining experimentally measured pressure distributions and numerical analysis. Experiments were conducted varying rates fin heights ranging from 40 L/min 180 range 5 mm–25 mm, respectively. A...
In the present work, scale effect on Boil-Off Rate (BOR) was investigated based an analytical method to systematically evaluate thermal performance of a Liquefied Natural Gas (LNG) Cargo Containment System (CCS). A two-dimensional resistance network model developed accurately estimate heat ingress into CCS from outside. The analysis performed for KC-1 LNG membrane tank under IGC and USCG design conditions. ballast compartment both cofferdam divided six sections made each section. To check...
본 연구에서는 슬롯제트 유동이 플레이트 히트싱크 열성능에 미치는 영향에 대해 분석하였다. 실험을 위해 40 × mm 크기의 히터와 히트싱크를 설치한 뒤, 윈드터널과 슬롯노즐을 통해 5, 10, 20, 30, 폭의 슬롯제트를 형성하여 히트싱크에 분사하였다. 이 때, 휜 높이는 20 mm로 조절되었다. 히트싱크의 열성능은 윈드터널의 출구부 압력과 주변 대기압과의 차이로 산출된 압력강하량과 히터에 가해진 열량 및 히터 온도로 정의된 열저항으로 평가되었다. 실험 결과, 동일 압력강하량 대비 열저항이 최소화되는 최적 슬롯폭이 존재함이 확인되었으며, 이는 충돌하는 균일해지는 지점과 일치함을 발견하였다. 또한, 슬롯폭은 높이가 높아질수록 증가하는 점을 확인하였다.
Abstract Recently, cryogenic fluids are widely transported via cargo ships as energy sources. The generation of boil-off gas (BOG) is inevitable in a container due to the large temperature difference. Therefore, accurately analyzing over time essential increase delivery efficiency and ensure tank safety. However, predicting rate (BOR) not simple task, both experiment calculation require significant amount time. In this study, predictive method developed for simulating 1/50 scaled model tank....

Accurate three-dimensional perception is a fundamental task in several computer vision applications. Recently, commercial RGB-depth (RGB-D) cameras have been widely adopted as single-view depth-sensing devices owing to their efficient abilities. However, the depth quality of most RGB-D sensors remains insufficient inherent noise from environment. studies focused on enhancement cameras. Recent research has proposed deep-learning-based approaches that typically train networks using...
