Paddle propulsion mechanisms on water mobile robots

Today, boats are used as a means of transport on water. Screw propellers are mainly used as propulsion systems for ships, and are available in a wide range of shapes and with many variations, such as those in which the direction of the blades can be changed, and are used in a wide range of applications. However, while screw propellers are convenient, they have a number of problems: first, if the rotational speed is increased too much to increase the propulsion speed, cavitation can occur, resulting in a significant reduction in propulsion efficiency.The second problem is that the propeller's rotation can cause algae and debris to become entangled in the propeller, causing it to stop and malfunction, and the third problem is that contact between the propeller and aquatic organisms can cause injuries and even death. Therefore, as a precondition, attention is paid to the paddle propulsion system, which has fewer of the above-mentioned dangers. This method of propulsion is typical of outer-wheel boats and oars, which do not rotate at high speed and therefore do not cause cavitation. It also attracts less algae and debris because the water flow is not in only one direction towards the propulsion machine body. And because the paddles are scraped at low speed, damage is considered to be minimal in the event of contact with organisms. In this study, the robot is created to mimic the seagull, a creature that swims on water.
Characteristics of Hammering Position of Experts in Automobile Sheet Metal Dent Repair

Hammering sheet metal is a work to repair the unevenness of car body using by just hammer and dolly. Sheet metal engineers are required to have a high level of skill because the shape of the car body to be repaired is different each time. The purpose of this study is to clarify the position of the hammering position and the position of the dolly during hammering by experts, and the distance between the dent and the hammering position and the dolly. The sheet metal engineers were instructed to repair the fender with a dent that looked like the damage by hammering sheet metal. A 3D motion analysis system measured this repair. As a result, the experts hammered above or a 25 mm range below the dent while changing the position to the left and right of the dent. In many cases, the dolly moved in conjunction with the hammering position.

The Proposal of Method to Support Metaverse Meeting By Detecting User’s Nods and Changing Avatar’s Transparency

Users can participate in the metaverse meeting with or without HMDs. However, it is difficult to convey the non-verbal information such as facial expressions and eye contact unlike face-to-face communication. This makes it difficult for the speakers to recognize whether the listeners are listening or not. In this research, we propose the system’s design that detects nods and change the transparency of the avatar according to the number of nods to visualize whether listeners are listening to the conversation.
Evaluation of mechanical energy for human dynamics using posture estimation method

The purpose of this study is to realize a tailor-made exercise evaluation technology that can simultaneously perform highly accurate estimation of activity energy expenditure (AEE) and posture measurement during exercise in order to provide tailor-made training content, exercise intensity, and competition time according to the individual. To this end, we developed a measurement system that integrates three technologies: marker-less motion capture, human body dimension measurement, and activity energy expenditure estimation (AEE estimation) based on mechanical energy. Using the measurement system, AEE estimation was performed for two exercises (Arm Swings and Standing Jumps). The results showed that the proposed method is more individualized than the conventional method for the exercise in which a major part of the body moves. In addition, the AEE estimation of the proposed system can be applied to arbitrary movements because the calculation is based on the 3D posture estimation by FrankMocap and the change in mechanical energy.
Practice of Cross-Departmental Competition Using AI Autonomous Driving Technology Education Teaching Material

It is important to further improve autonomous driving technology from the viewpoint of not only reducing vehicle accidents, but also reducing the burden on drivers, improving public transportation, and solving the labor shortage at logistics sites. Therefore, there is an urgent need to train engineers who understand autonomous driving technology and learn how to use it. Engineers involved in autonomous driving are required to have not only vehicle dynamics and control, but also expertise in information systems, as well as knowledge and experience in autonomous driving using AI. The authors have developed educational materials for AI autonomous driving technology, and practiced using the teaching materials according to classroom lectures on vehicle motion and AI. We aimed to develop human resources that contribute to the new development of the industry by holding competitions that compete for comprehensive performance of vehicle motion, control, AI, etc. using these AI-equipped vehicle learning materials. Information system department and mechanical system department participated in this trial of new utilization. This paper describes the practice of an AI automated driving competition with the participation of students from multiple departments as a cross-disciplinary competition and its effects.

The Texture Developed by Manufacturing the Spring Made of SWOSC-V

The texture of springs is related to fatigue, creep, and especially strength. We investigated the microstructure in order to clarify the changes of the texture during the manufacturing process of the springs, and to contribute to further strengthening of springs. In this study, we simulate the texture produced by drawing and coiling wires in the spring manufacturing according to the predictive theory of crystal rotation based on Katoh's theory, which is based on the theory of Taylor et al. Also, we observed the crystal structure of the drawn and oil-tempered wires by electron backscattering diffraction (EBSD), and it was observed that the axial direction of crystal orientation rotates toward <110>. This result follows the predicted ones. Next, in order to predict the crystal direction rotated by coiling, we used finite element analysis (FEM) to identify the plastic strain generated during the coiling process, and input them to that theory for crystal rotation. The results show that the axial crystallographic orientation <110> relaxes on the outside of the wire cross section and also, while on the inside, the orientation accumulated around the crystallographic orientation <110> on the inside during the coiling process.

This research aims to improve the design method of the joystick control device in order to develop the system using various drones. Experimental results to verify the effectiveness of the system with the joystick control device developed using the improved design method are presented.
Activity Report of Open Seminar for Elementary and Junior High School Students Using FDM Type 3D Printer and Open Source 3D CAD

Recent years, the programing and the robot assembly exercise class are established at many tutoring schools “Juku” for elementary and junior high school students, because of starting the programing education at the elementary and junior high school. The primal purpose of these exercise are grow up the logical thinking ability and skill. On the other hand, these exercises are almost less mechanical engineering factor, although using robot educational kit. In this study, I carried out the open seminar for elementary and junior high school students using FDM type 3D printer and open source 3D CAD. The primal purpose of the open seminar is make opportunity to experience about 3D modelling and additive manufacturing such as 3D printing.
Reducing the Weight of Precision Ball Screw Shafts Using Drawing

In recent years, there has been a demand for lightweight shaft products to improve the tact time of equipment. Shaft products are stepped in order to use bearings at the shaft end. Therefore, drilling a hole in the center of a shaft product is not enough to reduce the weight of the product to ensure the wall thickness. Therefore, focusing on swaging technology, a type of drawing, we devised a weight reduction method in which both ends of a thin-walled steel pipe are plastically formed to form the shaft end and a structure with a large space inside is created. The thin-walled steel pipe is swaged to form the shaft ends, grooved with threads, heat-treated, and finished to produce a lightweight product. Calculation results show that the weight is 54% of that of the conventional product, a significant weight reduction. The allowable speed can be increased to 125% of the conventional product, which may contribute to an improvement in tact time. The prototypes manufactured by the drawing process showed no difference in appearance from the conventional product, and the measured weight was 55% of the conventional product, almost exactly as calculated. As a result of devising a weight reduction method using the drawing process and manufacturing a prototype, the possibility of significantly reducing the weight of a shaft product was seen. We will continue to evaluate the performance and life of the product in order to commercialize it.
Fostering human resources who aspire to the field of Mechanical Engineering

The number of applicants for the Faculty of Engineering, which has been decreasing since 1999, has been increasing since 2007. While the number of applicants for the Faculty of Information Engineering is increasing, the field of Mechanical Engineering which has a strong image of hardware is on the decline in popularity. However, the vast majority of "things" that enrich our lives are produced by Mechanical Engineering. In order to support people's safe and secure lives in the future, it is necessary to secure human resources who aspire to Mechanical Engineering. Therefore, in this paper, we considered how to increase the number of children who aspire to Mechanical Engineering by using the questionnaire results in the experiential learning for students in the junior high school and high school ages.
Preparation of On-demand Type Contents in the Face-to-face Classes

A simple and inexpensive approach to making the on-demand type learning contents while giving the face-to-face lecture in the class was reported. Screen images of the video projector in the classroom and explanation voices of the teacher are recorded as a video file. The teacher uses the Bluetooth headset to allow moving away from the computer connected to the projector. The wireless ring mouse is also used to indicate the contents and make slides work. The recorded files are placed on the learning management system after the class so that the students who could not attend the face-to-face class due to anxiety about COVID-19 and other unavoidable reasons could take a lecture in the form of the on-demand type distance learning. It was demonstrated that the reported approach is useful for preparing the distance learning contents to avoid significant deterioration of content quality without taking much time and effort.
Plot-aware transformer for recommender systems

&lt;abstract&gt; &lt;p&gt;Plot text is very valuable supporting information in movie recommendations. It has several characteristics: 1) It is rich in content. Each movie often has a document of more than 200 words to describe it, which can give the movie a rich semantic meaning. 2) Objectivity. Plot texts are different from review information. A movie may have thousands of reviews with mixed and conflicting opinions. However, a film has only one plot text, which is fair in tone and does not take a position. Despite its appealing properties and potential for accurate movie portrayal, the lack of a building block for effectively mining plot semantics has led to the marginalization of plot text in the design of movie recommendation algorithms. Therefore, in this paper, we explore the application of the Transformer, currently the best natural language processing module, to learning movie plot texts to help achieve more accurate rating prediction. We propose the "Plot-Aware Transformer" model (PAT) to model the process of "user-movie" rating interaction. We test the PAT model on several movie datasets and demonstrated that the model is competitive. In all tasks, PAT achieves state-of-the-art performance compared to baseline experiments.&lt;/p&gt; &lt;/abstract&gt;

Converting Voice Signal to Visual Indian Sign Language (ISL)

Deaf people utilize sign language, a symbolic representation, as their primary language. In contrast to acoustically transmitted sound patterns, sign language efficiently communicates through body language and posture. It could be used to communicate with both non-hearing impaired people and people who have difficulty speaking. Our programme aims to close the communication gap between these Deaf people and hearing people by utilizing emerging technologies including web applications, machine learning, and natural language processing. The basic goal of this paper is to create software or an interface that takes audio and voice as input and converts it to the appropriate sign language for deaf individuals. At the same time, body motions, posture, and hand formations are all synchronised. The method consists of two steps: first, voice-to-text API is used to convert speech to text; second, Parse Trees are used to represent the text and Natural Language Processing semantics (NLTK in particular) are used for lexical analysis of Sign Language Grammar. The writing adheres to the grammar principles of ISL (Indian Sign Language) and expands upon them. This stand-alone web application, which can be used on mobile devices and can be incorporated into various gadgets for the general public in public areas throughout India, seeks to be useful on a personal level as well.

Keyword Research

Behind every query a user enters within a search engine is a word or series of words. For instance, a user may be looking for a “hotel” or perhaps a “hotel in New York City.” In search engine optimization (SEO), keywords are invariably the target, providing a helpful way of understanding demand for said queries and helping to more effectively understand various ways that users search for products, services, organizations, and, ultimately, answers.
Authority

Authority is arguably 50% of the Google algorithm. You could optimize your site to your heart’s content by creating the perfect content and deliver it with the perfect UX that’s hosted on a site with the most perfect information architecture, only to find it’s nowhere in Google’s search results when searching by the title of the page – assuming it’s not a unique search phrase, so what gives?
Site Migration Planning

This chapter covers site migration mapping so that you could set the structure of your new site and semiautomate the formation of your migration URLs. The following are some of the techniques we’ll be using:
Trial on Design Ideation through Computational Knowledge Extension and Recall Enhancement

Recently in the field of design, it is becoming more important to generate innovative ideas of "what to create" at early design stage than ideas of "how well to make". At early design stage, compared to middle and downstream stages, information technology support has not been fully realized. In this research, based on the knowledge of cognitive neuroscience that "human creation does not create something out of nothing, but the memory of the past is the basis of creation", a database of functions and UXs of existing examples is prepared as an extension of human memory. And database exploration using similarity calculations with a concept dictionary enhances recall. Using the database, experiments to coming up to ideas for solving a problem. From the results, the effectiveness and possibility of the proposed method are confirmed.
A Study for Extracting Product Usage and Feeling of Use from User Reviews

In this research, methods of extracting product usage and feeling of use from collected user reviews are investigated. Although most conventional data mining methods extract data based on commonality and similarity, we tried two approaches to extract data not only by commonality and similarity but also on differences. In the method using sentiment analysis, it was confirmed that there is a positive correlation between the result obtained from the sum of the polar values and the rating based on the number of stars. In the method using co-occurrence networks, a method of extracting features of two product was proposed. On this method, the results of the difference operation after normalizing the frequencies of words contains each products’ reviews are used to construct a network that integrates the co-occurrence networks of the two products, and to extract features from the obtained network. Finally, as a result of applying the proposed method to a portable fan and a tabletop fan, it was shown that the features can be extracted well.
Free descriptive analysis of Review evaluation using tf-idf method

This paper describes the free description analysis on review comments evaluation using the tf-idf method, which is one of the machine learning methods. This study selected three types of comics YouTube video an evaluation target, performed machine learning by TF-IDF on the comment of the corresponding YouTube video as subjective free description data, extracted the feature values for each video, and visualized them using WordCloud tool. By conducting a questionnaire on these videos, subjective evaluations were obtained by SD method. Comparing the results obtained by machine learning with the results from the questionnaire, this study verifies the validity of the review evaluation using tf-idf method.
Proposal of Definitions and Quantitative Evaluation Methods for Exploration and Exploitation in Product Design and Development

Recently, it has been said that ambidexterity of exploration and exploitation is necessary for organizations to sustainably meet the needs of society and users in the rapidly changing business environment. However, no design methodology has been established to balance them and respond to uncertain future needs. Toward achieving both exploration and exploitation in product design and development, this paper proposes their definitions and the quantitative evaluation methods for their degrees based on the definitions. In these methods, words related to product functions and numerical values related to product attributes were extracted from design documents, and their differences from past documents were evaluated. Furthermore, to verify the proposed methods, they were applied to past products, for which the relationship between exploration and exploitation has been clarified. The verification showed that the evaluation results were consistent with the relationship, indicating that the proposed methods were potentially applicable to the evaluation of the degrees of exploration and exploitation.
