  • SMC - A Fuzzy Spiking Neural Network with State Transition Diagram for Behavior Estimation in Elderly Health Care System
    2019 IEEE International Conference on Systems Man and Cybernetics (SMC), 2019
    Co-Authors: Shuai Shao, Naoyuki Kubota
    Abstract:

    In recent years, the aging of the population has become a critical social issue that plagues developed countries such as Japan. We aim to alleviate the lack of health care for the elderly caused by inadequate caregivers through technical means. This paper develops an elderly health care system based on the information structure space. We chose to use physical sensors to estimate the behavior of older people. We use fuzzy spike neural networks to adapt to differences in different home environments and post-process with State Transition Diagrams to improve precision. In the experiment, we used the temperature and humidity data to evaluate the behavior of the bathroom. The results show that the system can accurately estimate human behavior with a precision of 79% and a time delay of 1.7 minutes.

  • Multiple impacts: A State Transition Diagram approach
    The International Journal of Robotics Research, 2012
    Co-Authors: Yanbin Jia, Matthew T Mason, Michael A Erdmann
    Abstract:

    Impact happens when two or more bodies collide, generating very large impulsive forces in a very short period of time during which kinetic energy is first absorbed and then released after some loss. This paper introduces a State Transition Diagram to model a frictionless multibody collision. Each State describes a different topology of the collision characterized by the set of instantaneously active contacts. A change of State happens when a contact disappears at the end of restitution, or when a disappeared contact reappears as the relative motion of two bodies goes from separation into penetration. Within a State, (normal) impulses are coupled differentially subject to relative stiffnesses at the active contact points and the strain energies stored there. Such coupling may cause restart of compression from restitution during a single impact. Impulses grow along a bounded curve with first-order continuity, and converge during the State Transitions. To solve a multibody collision problem with friction and tangential compliance, the above impact model is integrated with a compliant impact model. The paper compares model predictions to a physical experiment for the masse shot, which is a difficult trick in billiards, with a good result.

  • a State Transition Diagram for simultaneous collisions with application in billiard shooting
    WAFR, 2009
    Co-Authors: Yanbin Jia, Matthew T Mason, Michael A Erdmann
    Abstract:

    This paper models a multibody collision in the impulse space as a State Transition Diagram, where each State represents a phase during which impacts are “active” at only a subset of the contact points. A State Transition happens whenever an active impact finishes restitution, or an inactive impact gets reactivated, depending on whether the two involved bodies are instantaneously penetrating into each other or not. The elastic energy due to an impact is not only affected by the impulse at the corresponding contact point, but also by other impulses exerted on the two involved bodies during the impact. Consequently, Poisson’s impulse-based law of restitution could result in negative energy. A new law governing the loss of elastic energy during restitution is introduced. Convergence of the impulse sequence generated by the State Transition Diagram is established. The collision outcome depends on the ratios of the contact stiffnesses rather than on their individual values. The collision model is then applied in an analysis of billiard shooting in which the cue stick impacts the cue ball, which in turn impacts the pool table. The system is driven by the normal impulses at the two contacts with the tangential impulses determined via a contact mode analysis.

  • NBiS - A Graphical Front-End Interface for React.js
    Advances in Network-Based Information Systems, 2018
    Co-Authors: Shotaro Naiki, Shusuke Okamoto, Masaki Kohana, Masaru Kamada
    Abstract:

    We present a graphical front-end interface for creating dynamical web pages by means of React.js. Its user does not have to write JavaScript codes for specifying the dynamical behavior of the web components but has only to draw State-Transition Diagrams graphically on the developed graphical editor. Using the graphical editor, the user composes a State Transition Diagram that specifies the dynamical behavior of each web component in terms of circles representing the States of the component and arrows representing the conditioned Transitions among the States. Then the developed translator converts the State Transition Diagrams into web components of React.js in JavaScript that compose the target web page. This system of the graphical editor and the translator enables general users without knowledge and experiences in programming to create dynamical web pages. Wanna-be programmers may start learning JavaScript and React.js by comparing their Diagrams and the translated JavaScript codes.

  • NBiS - Development of IslayPub3.0 - Educational Programming Environment Based on State-Transition Diagrams
    2015 18th International Conference on Network-Based Information Systems, 2015
    Co-Authors: Kazuomi Suzuki, Michitoshi Niibori, Shusuke Okamoto, Adnan Saleh Rashed, Masaru Kamada
    Abstract:

    An enhanced version of IslayPub is developed in this study. IslayPub is an educational programming environment available on any browsers capable of HTML5 and JavaScript. Its unique feature is to describe the behavior of automatic characters in terms of State-Transition Diagram visually easy to understand even for children. The former version did not offer the functions of publishing what they created and receiving likes and comments from others. In this paper, we enhance IslayPub to include those two functions which will give more fun and motivation to the children.

  • NBiS - IslayTouch: An Educational Visual Programming Environment Based on State-Transition Diagrams that Runs on Android Devices
    2015 18th International Conference on Network-Based Information Systems, 2015
    Co-Authors: Erjing Zhou, Shusuke Okamoto, Masaru Kamada, Michitoshi Niibori, Tatsuhiro Yonekura
    Abstract:

    Educational programming languages are programming languages that have been designed for beginners, with the purpose of teaching them the skill of logical thinking or as an introduction to regular programming languages. Although these languages are relatively easier for beginners, difficult concepts of regular programming languages are still being introduced into some of them. As a new approach to this problem, an educational visual programming environment called Islay has been developed. Due to the adoption of the simple concept of State-Transition Diagram, Islay becomes even easier for beginners than some other educational programming languages. In this research, a new version of Islay is developed as an Android application, with more features being added and a new user interface that is suitable for tablet devices.

  • NBiS - Interactive Animation Authoring Platform Based on State-Transition Diagrams that Runs on Android Devices
    2014 17th International Conference on Network-Based Information Systems, 2014
    Co-Authors: Erjing Zhou, Shusuke Okamoto, Masaru Kamada, Michitoshi Niibori, Tatsuhiro Yonekura
    Abstract:

    An interactive animation is a presentation of moving pictures that behave dynamically according to the input from users. It can be composed of animation characters modeled as finite-State machines. Based on the fact that the behavior of a finite-State machine can be defined by a State-Transition Diagram, an interactive animation authoring tool called Islay has been developed. Islay allows users to create interactive animation simply by drawing State-Transition Diagrams on a GUI-based editor. Up to now Islay mainly runs on the PCs. But we cannot use it on the portable devices that have become popular recently. In this research, a new version of Islay that runs on Android devices is developed with its user interface adapted to the touch screen interface.

  • Islay3D—A Programming Environment for Authoring Interactive 3D Animations in Terms of State-Transition Diagram
    Journal of Software Engineering and Applications, 2014
    Co-Authors: Dandy Ling Kwong, Shusuke Okamoto, Masaru Kamada, Michitoshi Niibori, Tatsuhiro Yonekura
    Abstract:

    An educational programming language is a programming language that is designed primarily as a learning instrument and not so much as a tool for writing programs for production. Three-dimensional (3D) interactive animations provide an effective means to engage the attention of the audience to learn programming language. Traditionally, creating 3D games had been difficult as it requires specialized programming skills. However, it had been proven that the State-Transition Diagram, which is the most fundamental principle for automata, is intuitively so comprehensive that even children can create programs for interactive animations and video games in the two-dimensional world. Islay3D is a programming environment for authoring interactive 3D animations based on this concept. In this paper, the Islay3D animation language is introduced, where a character is modeled as an object, and its behavior is defined in term of a set of State-Transition Diagrams. The interpretation of the State-Transition Diagrams to JavaScript is also presented. Finally, the web-based programming environment is introduced. With the web-based platform, the public will be able express their creativity in creating interactive 3D animations and video games easily from within their browser.

  • CIS (2) - Building security requirements using State Transition Diagram at security threat location
    Computational Intelligence and Security, 2005
    Co-Authors: Seong Chae Seo, Jin Ho You, Young Dae Kim, Jun Yong Choi, Sang Jun Lee, Byung Ki Kim
    Abstract:

    The security requirements in the software life cycle has received some attention recently. However, it is not yet clear how to build security requirements. This paper describes and illustrates a process to build application specific security requirements from State Transition Diagrams at the security threat location. Using security failure data, we identify security threat locations which attackers could use to exploit software vulnerabilities. A State Transition Diagram is constructed to be used to protect, mitigate, and remove vulnerabilities relative to security threat locations. In the software development process, security requirements are obtained from State Transition Diagrams relative to the security threat location.
