RainSD: Rain Style Diversification Module for Image Synthesis Enhancement using Feature-Level Style Distribution
Autonomous driving technology nowadays targets to level 4 or beyond, but the
researchers are faced with some limitations for developing reliable driving
algorithms in diverse challenges. To promote the autonomous vehicles to spread
widely, it is important to address safety issues on this technology. Among
various safety concerns, the sensor blockage problem by severe weather
conditions can be one of the most frequent threats for multi-task learning
based perception algorithms during autonomous driving. To handle this problem,
the importance of the generation of proper datasets is becoming more
significant. In this paper, a synthetic road dataset with sensor blockage
generated from real road dataset BDD100K is suggested in the format of BDD100K
annotation. Rain streaks for each frame were made by an experimentally
established equation and translated utilizing the image-to-image translation
network based on style transfer. Using this dataset, the degradation of the
diverse multi-task networks for autonomous driving, such as lane detection,
driving area segmentation, and traffic object detection, has been thoroughly
evaluated and analyzed. The tendency of the performance degradation of deep
neural network-based perception systems for autonomous vehicle has been
analyzed in depth. Finally, we discuss the limitation and the future directions
of the deep neural network-based perception algorithms and autonomous driving
dataset generation based on image-to-image translation.Comment: Under Revie
Rapid suppression of quantum many-body magnetic exciton in doped van der Waals antiferromagnet (Ni,Cd)PS3
The unique discovery of magnetic exciton in van der Waals antiferromagnet
NiPS3 arises between two quantum many-body states of a Zhang-Rice singlet
excited state and a Zhang-Rice triplet ground state. Simultaneously, the
spectral width of photoluminescence originating from this exciton is
exceedingly narrow as 0.4 meV. These extraordinary properties, including the
extreme coherence of the magnetic exciton in NiPS3, beg many questions. We
studied doping effects using Ni1-xCdxPS3 using two experimental techniques and
theoretical studies. Our experimental results show that the magnetic exciton is
drastically suppressed upon a few % Cd doping. All these happen while the width
of the exciton only gradually increases, and the antiferromagnetic ground state
is robust. These results highlight the lattice uniformity's hidden importance
as a prerequisite for coherent magnetic exciton. Finally, an exciting scenario
emerges: the broken charge transfer forbids the otherwise uniform formation of
the coherent magnetic exciton in (Ni,Cd)PS3.Comment: 40 pages, 4 main figures, 13 supporting figures, accepted by Nano

Dynamic Skinning for Popping Dance
Abstract. This paper presents an efficient technique to enhance the realism of character animation by adding muscle dynamics. Focusing on the isometric contraction of muscles, the proposed algorithm takes normal mesh and clenched mesh, and uses the disparity between them to simulate the skin vibration. The skin simulation algorithm is integrated with an example-based skinning, and shows real-time performance. The proposed approach proves to be useful for animating popping dance
Unravelling the Influence of Buddhist Liberal Arts Education on College Studentsā Self-Reflection
The purpose of this paper is to investigate the measurable impact of Buddhist liberal arts courses on college studentsā ability to engage in self-reflection. This study uses the data gathered to establish, through statistical analysis, any correlations between two variablesāBuddhist liberal arts as courses as the independent variable and self-reflection intelligence as the continuous dependent variable. First, the following results of the study show that the mean of the four self-reflection sub-categories for the students who found that the courses were helpful was higher than that of the students who found that they were not helpful: self-awareness (4.10 Ā± 0.49 > 3.90 Ā± 0.87), self-design (3.84 Ā± 0.66 > 3.40 Ā± 0.97), self-regulation (4.01 Ā± 0.04 > 3.48 Ā± 0.18), and self-examination (4.21 Ā± 0.03 > 3.94 Ā± 0.15), respectively. Second, the mean of the four self-reflection sub-categories for students who experienced a positive change of their perception in the courses was higher than that of students who experienced a negative change, as follows: self-awareness (4.08 Ā± 0.50 > 3.75 Ā± 0.82), self-design (3.84 Ā± 0.68 > 3.51 Ā± 0.93), self-regulation (4.00 Ā± 0.59 > 3.56 Ā± 0.67), and self-examination (4.17 Ā± 0.49 > 4.04 Ā± 0.73), respectively. This study illuminates the role of Buddhist-related liberal arts courses in higher education, specifically in fostering studentsā self-reflection skills. It offers valuable insights into educational practices aimed at enhancing self-reflection levels
Effects of Anodizing Conditions on Thermal Properties of Al 20XX Alloys for Aircraft
Anodizing was applied to improve the heat dissipation performance of aluminum (Al) alloys, by forming an oxide layer, such that they could be employed in aerospace applications. The methods employed were hard sulfuric acid (high hardness), soft sulfuric acid (low hardness), boric-sulfuric mixed acid, tin-sulfuric mixed acid, and chromic acid solutions. Each process was completed under optimized conditions. The surface morphology was observed using field emission scanning electron microscopy (FE-SEM) and a digital camera. For the determination of thermal performance, Fourier transform infrared spectroscopy (FT-IR) was used to measure the emissivity at 50 Ā°C, and laser flash analysis (LFA) was utilized to analyze the thermal diffusivity at room temperature to 300 Ā°C. The radiative property of metals is often ignored because of their low emissivity, however, in this research, the emissivity of the metal oxides was found to be higher than that of bare metal series. This study improved the heat dissipation properties by oxidization of Al via the anodizing process
