Abstract We demonstrate long-range enhancement of fluorescence and Raman scattering using a dense random array Ag nanoislands (AgNIs) coated with column-structured silica (CSS) overlayer over 100 nm thickness, namely, remote plasmonic-like (RPE). The CSS layer provides physical chemical protection, reducing the impact between analyte molecules metal nanostructures. RPE plates are fabricated high productivity sputtering immersion in gold(I)/halide solution. plate significantly enhances...
Predominant evidence of non-alcoholic fatty liver disease (NAFLD) is the accumulation excess lipids in liver. A small group with NAFLD may have a more serious condition named steatohepatitis (NASH). However, there lack investigation accumulated spatial and molecular information. Raman microscopy has potential to characterise species structures based on vibration can achieve high resolution at organelle level. In this study, we aim demonstrate feasibility for features lipids. By applying NASH...
Currently, authentication methods using ID and password are widely used fulfilled central roles in various information systems services. Our university also uses for of most However, passwords have problems such as reuse, phishing leakage. This research is a practical experiment order to implement an integrated system without password. Shibboleth introduced our university, providing capabilities web single sign-on attribute exchange framework organizational The Fast IDentity Online (FIDO)...
In recent years, WDM networks have received much attention as the Internet backbone because of explosive growth IP-based traffic. The optical burst switching (OBS) has been proposed an effective technology in (C. Qiao and M. Yoo, 1999). OBS advantages 1) high usage rate bandwidth, 2) no necessity buffer. However burst-contention problem networks. deflection routing is one means to solve this problem. paper, we propose a new method using routing. addition, QoS/CoS control algorithm. Finally,...
Fast and scalable Content-Based Image Retrieval using visual features is required for document analysis, Medical image etc. in the present age. Convolutional Neural Network (CNN) activations as achieved their outstanding performance this area. Deep representations softmax function output layer are also ones among features. However, almost all retrieval systems hold index of on main memory order to high responsiveness, limiting applicability big data applications. In paper, we propose a fast...
Sports analytics aims to provide a competitive advantage team or individual in sports by analyzing collection of relevant statistics. Better strategies play can be formulated using the information. The core technology necessary for analysis is player detection and tracking. Due limitation fixed cameras, this work presents court markers, tracking drone. method presented based on perspective transformation, template matching particle filters. In work, we visualize movement trajectory extract...
Basketball is one of the most popular team-sports played on a shared court. It important to shoot basket based predominant strategy. In terms individual movement along with strategy, it necessary for an offense player understand how easily in organized team-play. this study, we introduce basic tactics and propose environment automatic extraction scenes applying them from tracking data players ball. We also analyze applied tactics, which are linked motions their goals.
The modern field of machine learning has made remarkable progress, and the demand for training data required by systems is constantly increasing. However, annotation work to create this requires a great deal effort. Therefore, we considered semi-automating labeling process taking advantage false positives that occur when object detection performed YOLOv5, thereby eliminating need region selection reducing cost work. In comparison experiment with labelImg, common tool, found took less time...
Integrated movement, which is comprised of several motor-skills requires appropriate arrangement motions at each body part. Most team sports follow such integrated movements. This study focuses on learning and training the feint motion in one-on-one scenes a sport, basketball. We aim designing developing supporting system for this target. The timing change movement offense player main concern. methodology creating virtual defense as partner real proposed. Moreover, we tested prototype...
Programming education will be compulsory in elementary schools Japan from 2020, but it is still little information on how to measure the effects of lessons conducted for students. In this study, objectively and quantitatively educational effect programming education, we developed a test measuring ability thinking as way programming. paper, evaluate measurability using Fisher's exact school students' answers, focusing grade, experience, difference between results before after workshop.
In terms of basketball, a player always decides an option the next movement what leads to get score. this research, we propose environment focusing on ball holder, who has select action. As support, our visualizes options for holder's actions. Furthermore, positional relationship among players is measured from coordinate obtained game data, and system caliculates provides information about how easy We design such with these functions so that user can learn movement.
This study discusses the design issues of human-computer-interaction environment for developing recognition skills a basketball player in one-on-one situations. Further, two types actual implementations are proposed supporting slight movement offense and defense repeatedly. Trainees lack physical opponents when they want to have one-onone training session. Thus, this designs software-based opponent single trainee who has limited space world. Firstly, system monitors analyzes player's body...

The performance of ChatGPT\copyright{} and other LLMs has improved tremendously, in online environments, they are increasingly likely to be used a wide variety situations, such as ChatBot on web pages, call center operations using voice interaction, dialogue functions agents. In the offline environment, multimodal also being realized, guidance by Artificial Intelligence agents (AI agents) tablet terminals systems form mounted robots. this dialogue, mutual emotion recognition between AI user...
In the near future, it will be essential for multimedia networks to satisfy multiple quality of service (QoS) requirements, such as bandwidth, transmission reliability, end-to-end delay etc. On other hand, multicast technology is being increasingly used in various continuous media applications that involve video and audio. particular, multipoint-to-multipoint communication services, including collaborations conferencing shared workspaces, widespread. However, when a conventional routing...
Recently, the use of Multi-Object Tracking(MOT) technology has become vital for sports analysis using video. The main advantages over GPS are mainly cost and non-interference with players. However, to estimate same real location comparable GPS, camera calibration play area dimensions detection necessary. This work, proposes a deep learning method player, ball field markers perspective transform determine players in irrespective position. Our results show that, this could be useful cheap both...
Player tracking has become a crucial technique for getting strategic advantage in competitive team sports. Movies captured by one or few cameras are easy to use this purpose at any level including amateur. This study describes design issue that integrates up-to-date technologies of multi-object tactics detection from the actual game data bring affordability, feasibility, and accessibility.
