This paper presents experimental results of cyclic voltammetry on CeCl3 in LiCl-KCl using tungsten electrode and Bi coated electrode respectively at 703K. Using tungsten electrode at low ...concentration of CeCl3, the redox reaction has been shown to be reversible. Diffusion coefficient and apparent standard potential of Ce(III) in LiCl-KCl were 0.42×10-5 (cm2/s) and -3.153 (V vs. Cl2/Cl−) under 50mV/s. In order to obtain Bi coated electrode, cyclic voltammetry was carried out on eutectic salt including BiCl3. The redox reaction of Ce on Bi coated electrode has been shown to be reversible and apparent standard potential on Bi coated electrode moved 782mV compared with tungsten cathode.

In this study, energy loss due to ventilation load in the dock system was analyzed through simulation. Also, flow generated in the dock system of the warehouse was measured using manufactured ...measuring devices. Numerical simulation was conducted by simulating the most common picking tasks by examining the actual working environment. Incompressible and unsteady turbulent flows were assumed, and the turbulence model was the k-e standard model. Proper grid was selected through grid dependency test. Measurement was conducted using Honeywell and Vaisala sensors, and flow and temperature inside the warehouse were measured and compared with simulation results to validate simulation. When comparing amount of loss occurring in two hours and amount of loss occurring in 15 minutes, docking time of the former was eight times longer but energy loss was 3.8 times lower. Ventilation load occurring during the initial period after opening docking system accounted for a large proportion of total ventilation load. Also, comparing the load when the dock was closed and the load when the truck was parked, ventilation load was significantly higher than load due to heat conduction from the wall. Therefore, in improving the docking system, it is effective to reduce the gap by improving compatibility of the docking system and truck, rather than wall material.
Online games with a variety of genres and game style have become popular. While the market for online games is growing, unauthorized program software is used and operated by some users. They damaged ...fair players and furthermore, bot program users have inflicted a huge loss to game service companies. Bot programs show various game play action styles and there are many users not only in Korea but also other countries, so it is not easy to trace. Also, as users of online game and smart device game which is focused recently are increasing, log data quantity are explosively increased and demands of analysis on not only bot information, but also statistical information which is necessary for game operation plan from log information. This paper examines bot program of online game, detection method and tendency of log data management technology for it. This paper introduces our method to detect game bots and manage game log data.

► Working stamp needs anti-adhesion layer for step and NIL repetition. ► We fabricated working stamps using PVSZ and Ormostamp materials. ► After repetition imprints, PVSZ stamp could ...be maintained contact angle. ► PVSZ stamp no needs surface modification and be used as an ideal stamp.
The feasibility of a sustainable imprint-working stamp made of polyvinylsilazane (PVSZ) is demonstrated. As a control stamp, the Ormostamp, which was typically used as an anti-sticky imprint-working stamp in previous related studies, was used. For the comparing experiments, two types of stamp using Ormostamp and PVSZ were prepared. The working stamp was fabricated by placing a defined amount of UV-curable material on the master stamp and UV curing. For the Ormostamp material, after the cured working stamp was detached from the master stamp, BGL-GZ-83 was coated on the surface of the working stamp and heat treatment was performed. For the PVSZ material, after the cured working stamp was detached from the master stamp, it was subject to heat treatment and hydrolysis treatment in vaporized aqueous ammonia. The nanoimprinting process was repeatedly carried out within polyurethane acrylate (PUA) resin. For the qualitative measurement of increasing surface energy after repeated imprinting, the contact angle of the working stamp made of Ormostamp material and PVSZ was measured before and after the imprinting experiment. According to the contact angle results of the Ormostamp and PVSZ, the PVSZ could be used as a more sustainable imprint-working stamp material than the Ormostamp. Accordingly, a PVSZ working stamp was successfully formed on a glass substrate with an anti-adhesion surface for UV-nanoimprint lithography.
Large language models (LLMs) have shown their capabilities in understanding contextual and semantic information regarding knowledge of instance appearances. In this paper, we introduce a novel ...approach to utilize the strengths of LLMs in understanding contextual appearance variations and to leverage this knowledge into a vision model (here, pedestrian detection). While pedestrian detection is considered one of the crucial tasks directly related to our safety (e.g., intelligent driving systems), it is challenging because of varying appearances and poses in diverse scenes. Therefore, we propose to formulate language-derived appearance elements and incorporate them with visual cues in pedestrian detection. To this end, we establish a description corpus that includes numerous narratives describing various appearances of pedestrians and other instances. By feeding them through an LLM, we extract appearance knowledge sets that contain the representations of appearance variations. Subsequently, we perform a task-prompting process to obtain appearance elements which are guided representative appearance knowledge relevant to a downstream pedestrian detection task. The obtained knowledge elements are adaptable to various detection frameworks, so that we can provide plentiful appearance information by integrating the language-derived appearance elements with visual cues within a detector. Through comprehensive experiments with various pedestrian detectors, we verify the adaptability and effectiveness of our method showing noticeable performance gains and achieving state-of-the-art detection performance on two public pedestrian detection benchmarks (i.e., CrowdHuman and WiderPedestrian).
Pedestrian detection is a crucial field of computer vision research which can be adopted in various real-world applications (e.g., self-driving systems). However, despite noticeable evolution of ...pedestrian detection, pedestrian representations learned within a detection framework are usually limited to particular scene data in which they were trained. Therefore, in this paper, we propose a novel approach to construct versatile pedestrian knowledge bank containing representative pedestrian knowledge which can be applicable to various detection frameworks and adopted in diverse scenes. We extract generalized pedestrian knowledge from a large-scale pretrained model, and we curate them by quantizing most representative features and guiding them to be distinguishable from background scenes. Finally, we construct versatile pedestrian knowledge bank which is composed of such representations, and then we leverage it to complement and enhance pedestrian features within a pedestrian detection framework. Through comprehensive experiments, we validate the effectiveness of our method, demonstrating its versatility and outperforming state-of-the-art detection performances.
