The impact on the performance of all-vanadium redox flow batteries by tin as an electrocatalyst through <italic>in situ</italic> electrodeposition is investigated.
We report amphoteric polybenzimidazole (PBI) membranes with tailored nanoporous structures for vanadium redox flow batteries (VRFBs).
Purpose Magnetic resonance imaging (MRI) artifacts are originated from various sources including instability of an magnetic (MR) system, patient motion, inhomogeneities gradient fields, and so on. Such MRI usually considered as irreversible, additional artifact‐free scan or navigator is necessary. To overcome these limitations, this article proposes a novel compressed sensing‐based approach for removal artifacts. Theory Recently, the annihilating filter based low‐rank Hankel matrix was...
Nafion, the most popular cation exchange membrane, was cast while charged in an electric field to enhance proton conductivity of membrane.
A low-resistance ion-exchange membrane is essential to achieve the high-performance energy conversion or storage systems. The formation methods for membranes are various; one of ion channel alignment an under a direct current (DC) electric field. In this study, we suggest more effective method than process with DC First, was prepared pulsed field [alternating (AC) mode] enhance effectiveness alignment. properties and performance in reverse electrodialysis (RED) were then examined assess...
Fabrication of high-conductivity ion exchange membranes (IEMs) is crucial to improve the performance non-aqueous vanadium redox flow batteries (NAVRFBs).
We investigate the effects of different ways visualizing virtual gait avatar in context Walk-in-Place (WIP) based navigation a environment (VE). In Study 1, participants navigated through VE using WIP method while inhabiting an avatar. varied visualization avatar’s leg motion performing gesture: (1) Fixed Body: legs stood still; (2) Pre-recorded Animation: moved fixed predetermined pace (plausible but not accordance to that user general); (3) Synchronized Motion according (synchronized)...
Traditionally, kernel services are of a higher priority than user processes. The can preempt the currently executed process in order to perform interrupt handling for behalf another process, even though latter is lower former. This be viewed as inversion. We propose new approach that couples scheduling with associated handle. present techniques derive exact priorities interrupts incoming network packets. proposed has been implemented Linux 2.6, and experiment results show it reduces...
재난안전에 대한 사회적 관심과 요구가 증가함에 따라 정부는 정책적으로 재난안전 확보를 위한 다양한 계획을 수립하고 있다. 이러한 계획 중 하나가 기술개발을 통한 관리 역량을 향상시키는 것이다. 이에 본 연구에서는 우리나라의 연구개발 관련 조사하고, NTIS(국가과학기술지식정보서비스)에 등록된 자료를 이용하여 최근 수행된 국가 R&D에 대하여 재난유형과 재난관리 단계에 분석하였다. 재난유형을 자연재난, 사회재난, 특수재난, 해양재난, 소방/기동의 5개 분야로 구분하여 분석한 결과, 사회재난 분야의 R&D 비중이 가장 컸다. 또한 단계는 예측, 예방, 대비, 대응, 복구, 플랫폼의 6개 유형으로 구분하였는데, 예방분야에 투자가 집중된 것으로 나타났다. 결과는 재난 대응역량 강화와 전주기 관리의 필요성을 보여준다고 판단된다. As social concerns and demands for safety increase, Korean government has established...
굴 패화석은 남해안의 굴양식 지역을 중심으로 발생량이 매년 증가되고 있으나 재활용율이 낮아 지역적으로 문제가 되므로 토양개량제로서 재활용하고자, 패화석에 소량 포함되어 있는 중금속이 배추의 수량 및 중금속흡수 특성과 토양 내 중금속의 이동성에 미치는 영향을 조사하여 다음과 같은 결론을 얻었다. 패화석 시용에 따른 0.1N HCl 가용 중금속 함량은 토양오염 우려기준 이하로 패화석을 다량시용 함에 중금속성분의 축적은 없었다. 시용량 증가에 따라 총 미미한 수준에서 증가하는 경향을 보였으나, 대부분의 중금속성분은 생물체 흡수가 불가능한 광물 고정된 형태(residual phase)로 존재하였다. 패화석의 시용량을 증가시킴에 배추 체내 Cu, Mo, Zn의 흡수량은 다소 보였으나 우려할 만한 수준은 아니었으며 생육기간 동안 육안적으로 특정 이온과다에 의한 독성증상은 나타나지 않았다. 이상의 결과를 통해 시용은 토양의 pH개선, 축적의 배제는 물론, 작물 수량증대에 효과가 현저하므로...
Navigation in the virtual environment is one of interactions which happens very frequently. Physical locomotion method popular due to its naturalness VR but it requires wide area. To use minimum space for navigation, walk-in-place suggested as an alternative way navigation. In this tutorial, we will cover following topics. 1) Treadmill based methods 2) Non-treadmill
We suggest an omnidirectional navigation and jumping method using walking-in-place (WIP) interface. This supports forward, backward, sideways walking include vertical jump. The shooting game is one of the contents that can best take advantage VR. Since WIP interface a hands-free method, it works well with VR game. However, we need to extend because this not possible for existing keyboards or joysticks. propose forward suitable Our inspired by human behavior state diagram support backward...
In this paper, we propose a sparse and low-rank decomposition of annihilating filter-based Hankel matrix for MRI artifact removal. Based on the observation that some MR artifacts are originated from k-space outliers, employ recently proposed image modeling method using approach (ALOHA) to decompose outliers component. Unlike recent low rank dynamic MRI, can be applied even static images, because component comes intrinsic properties. We demonstrate algorithm clearly removes several types such...
