  • A logical consideration on fraudulent email communication
    • Abstract: Abstract One of the most serious problems in modern society is that internet users are deceived by various fake information. In this paper, we analyse a scenario based on an actual incident of fraud called business email compromise (BEC). We suppose that each email, in the incident, step-wisely changes user’s thinking and makes him or her believe the emails. If fraud has such a step-by-step mechanism, it allows us to consider counter measures for dissuading a user from decision-making on the way. We discuss features and factors of the incident based on formulations of Channel theory. Our analysis revealed that each email message influenced user’s decision-making by what kind of logical trap. It can be fundamental knowledge that is capable of warning the user with predicting logical traps. This paper contributes to providing a novel viewpoint to develop systems for detecting deception of BEC.

  • A macroscopic theory for predicting catastrophic phenomena in both
           biological and mechanical chemical reactions
    • Abstract: Abstract A possibility for predicting the time-dependent pattern of sickness of human beings, i.e., biological catastrophe, has been shown by proposal of a nonlinear ordinary differential equation, describing temporal features of six macroscopic molecular groups chemically interacting in living beings, (Naitoh in Jpn J Ind Appl Math 28:15–26, 2011; Naitoh and Inoue in J Artif Life Robot 18:127–132, 2013). Logically, we also find that, six is minimum and essential as the number of macroscopic molecular groups for describing living systems. Then, along with the number theory applied for the differential equation, we derive critical mathematical conditions for predicting the premonition just before sickness (discrepancy from a healthy condition), which agree with an important knowledge revealed by the linear analysis proposed by Chen (Dynamical network biomarkers for identifying early-warning signals of complex diseases, Beppu, Oita Japan, 2015). In the present report, we first show that computational several time-histories of sickness obtained by solving the nonlinear differential equation with various parameters describing polymorphism agree well with actual time-dependent patterns of sickness for human beings, which is further evidence of usefulness of the nonlinear differential equation and its critical mathematical conditions. Thus, to examine the boundary between biological and abiological chemical reaction systems, which is related to the origin of living systems, we next check whether or not the nonlinear equation can also predict such abiological catastrophic phenomenon as misfire in artifacts including mechanical combustion engines.

  • An integrated machine code monitor for a RISC-V processor on an FPGA
    • Abstract: Abstract This paper proposes an integrated machine code monitor (iMCM) written in a hardware description language (HDL) and implemented in an FPGA together with a processor. The iMCM reconfigures monitor functions to be provided according to the verification progress of the processor design and the development situation of basic programs. The iMCM was implemented in the FPGA together with the processor as hardware synthesized from HDL description for requested iMCM functions. The iMCM was implemented its functions based on survey questionnaire result for six developers of some processors in FPGAs. And, its correct operation was confirmed by simulation and evaluation using FPGA devices. RISC-V was adopted as an ISA of the target processor. A subset composed of 27 instructions of the compression type instruction set extension with 16-bit instruction word length among RISC-V was employed. All state machines and sequential processes were written in Verilog HDL and implemented together with the processor core as a single circuit by circuit synthesis, placement, and routing. A 41% LUT was added to the implementation of the iMCM against the simple processor implementation. This addition depends on the monitor function to be selected and reconfigured. Furthermore, the iMCM programmed in the FPGA was confirmed to operate at 100 MHz with the circuit mounted on an FPGA evaluation board.

  • Prognostic medication: prediction by a macroscopic equation model for
           actual medical histories of illness with various recovery speeds
    • Abstract: Abstract A network theory model based on a nonlinear differential equation (Naitoh in Jpn J Ind Appl Math 28:15-26, 2011a; Proceedings of JSST 2011 international conference on modeling and simulation technology, pp 322–327, b, Naitoh and Inoue in J Artif Life Robot 18:127–132, 2013) macroscopically showed a possibility for explaining interaction mechanism of six groups of molecules on information and function in human beings. In this paper, we show that time-dependent computational results of the number of vigorous cells agreed well with individual medical histories of illness for actual patients. Computational results showed illness with three types of recovery speeds: illness with fast recovery speed having recovery period of several months, with medium speed like leukemia or small cell carcinoma having one or two-year-recovery period, and with low speed having recovery period about five years like the symptom of illness named “anti-N-methyl-d-aspartate (anti-NMDA) receptor encephalitis”. It is stressed that both of the period under unresponsive state in early stage and total years needed to recover cognitive function completely in anti-NMDA receptor encephalitis can be simulated. These results may indicate that the model macroscopically and essentially describes time-dependent activation level of human beings.

  • Evaluation of calibration methods to construct a 3-D environmental map
           with good color projection using both camera images and laser scanning
    • Abstract: Abstract In mobile robot navigation, restoration of the environment around the robot in a 3-D map is necessary for self-location, route planning, and detecting surrounding obstacles. We construct the 3-D color environmental map using both camera images and laser scanner (LIDAR) point cloud data. In the map, the RGB values are provided to the LIDAR point cloud data by projecting the point cloud onto the simultaneously acquired image. The projection parameters can be determined by measuring the calibration boards using both the camera and the LIDAR. In this paper, we have constructed a method to evaluate the accuracy of projection applicable to any calibration methods. And, then, we found that the calibration points in the central position of an image are important to obtain good projection parameters and that additional points at side positions also can improve the accuracy of the projection.

  • A waypoint navigation method with collision avoidance using an artificial
           potential method on random priority
    • Abstract: Abstract This paper proposes a waypoint navigation method with collision avoidance using an artificial potential method on random priority. To establish a multi-robot navigation system that consists of various tasks, the navigation system needs to avoid collisions by communicating with each robot path on-site. Robots have an autopilot system that includes waypoint navigation, but using this navigation method to avoid collisions is more difficult than using entire path planning. For waypoint-based path planning, we proposed a novel waypoint correction method using the artificial potential method with random priority. In addition to that, we proposed a speeding up algorithm for the artificial potential method with k-nearest neighbor and Delaunay triangulation. Our experimental results show that using random priority is sufficient to provide over 80% improvement to reach the desired speed, and the proposed random priority is similar to using general wireless conditions such as slotted ALOHA.

  • Safe mobile robot navigation in human-centered environments using a heat
           map-based path planner
    • Abstract: Abstract Safe robot navigation in human-centered environments is important to avoid collisions. A major limitation of the traditional path planning algorithms is that the global path is planned only with the knowledge of static obstacles in the map. This paper presents a novel ‘HMRP (heat map-based robot path planner)’ which uses fixed external cameras to generate a heat map of different passages based on congestion, so that robots can generate congestion-free paths at the global planning stage itself. The congestion values are maintained in a database and the paths are classified into hot and cold regions. Robot navigation is affected by the direction of movement of people. Hence, in this work, the HMRP-based planner also considers the direction of movement of people in passages which improves robot navigation. The proposed HMRP is compared with traditional path planning algorithms in real environment. Results show that the proposed HMRP algorithm generates congestion-free paths for safe robot navigation.

  • Brain–machine interfaces using functional near-infrared
           spectroscopy: a review
    • Abstract: Abstract Functional near-infrared spectroscopy (fNIRS) is a noninvasive method for acquiring hemodynamic signals from the brain with advantages of portability, affordability, low susceptibility to noise, and moderate temporal resolution that serves as a plausible solution to real-time imaging. fNIRS is an emerging brain imaging technique that measures brain activity by means of near-infrared light of 600–1000 nm wavelengths. Recently, there has been a surge of studies with fNIRS for the acquisition, decoding, and regulation of hemodynamic signals to investigate their behavioral consequences for the implementation of brain–machine interfaces (BMI). In this review, first, the existing methods of fNIRS signal processing for decoding brain commands for BMI purposes are reviewed. Second, recent developments, applications, and challenges faced by fNIRS-based BMIs are outlined. Third, current trends in fNIRS in combination with other imaging modalities are summarized. Finally, we propose a feedback control concept for the human brain, in which fNIRS, electroencephalography, and functional magnetic resonance imaging are considered sensors and stimulation techniques are considered actuators in brain therapy.

  • The evolution of cooperation based on indirect reciprocity and spatial
           locality in continuous space
    • Abstract: Abstract How cooperation evolves despite its disadvantage to local selfishness has been a challenging theme for many years. Several mechanisms have been proposed, among which reputation-based indirect reciprocity and spatial locality are two of the majors. However, only a few studies about their interaction exist. Here, we considered an agent-based model in a two-dimensional continuous space where not only the game-based interaction but also the transmission of agents’ reputation take place based on the spatial locality. Agents have one of the following three strategies as their gene: always defect, always cooperate or discriminate based on the recipient’s reputation. We tested four assessment rules in indirect reciprocity: Shunning, Stern Judging, Image Scoring and Simple Standing. We found that without mobility, first, as the spatial locality gets weaker, the cooperation rate drops. Second, for cooperation to evolve from an all-defector environment, the cluster of discriminators is necessary. We added mobility so that an agent will get closer to the one who donated to her and far away from the one who defected against her. We found that if the movement duration is long enough, a higher cooperation rate could be promoted.

  • A performance evaluation of read/write burst transfer by high-level
           synthesizable software for the alpha blending processing
    • Abstract: Abstract High-level synthesis, HLS is a technology to convert the software into the hardware automatically. It is expected as a technology that can greatly reduce the load of the hardware development. However, the current HLS that cannot convert the software not considered the hardware configuration into the optimum hardware. One of characteristics of the hardware to be considered is the burst transfer of memory access. In this paper, we evaluate the burst transfer with a subject of alpha blending processing as a theme. It is necessary to describe the program, so that the HLS tool can implicitly infer the burst transfer, because HLS tool does not have a pragma designating the burst transfer. We consider the description method of the program to infer the burst transfer and clarify the influence of read/write burst transfer on alpha blending.

  • Dual-arm robot teleoperation support with the virtual world
    • Abstract: Abstract This paper describes the construction of an operator support system for teleoperation of dual-arm robots in the real world and the virtual world. The robot simulator Choreonoid was implemented to create a virtual space. We focus on dual-arm robot teleoperation in particular because it is difficult for the operator to operate a dual arm with one controller. In the verification experiment for usability, through the use of questionnaires and statistical analysis, we show that it is possible to reduce the risks involved in dual-arm operation for a novice teleoperator by comparing the case when the virtual space was confirmed with when it was not.

  • Adaptive tracking controller for hexacopters with a wind disturbance
    • Abstract: Abstract In this paper, we propose an adaptive trajectory tracking control scheme for hexacopters with a wind disturbance. Using conventional controllers, position and attitude of hexacopters cannot be controlled independently. Using tilted rotors, it is expected that the problem of conventional controllers can be overcome. Therefore, we will develop an adaptive trajectory tracking controller for hexacopters with tilted rotors. The developed controller can ensure good control performance even if there exist uncertainties and unknown wind disturbances. Finally, to confirm the usefulness of the proposed controller, numerical simulations are carried out.

  • A design of EPIC type processor based on MIPS architecture
    • Abstract: Abstract This paper proposes an EPIC (Explicitly Parallel Instruction Computing Architecture) type processor based on MIPS. VLIW processors can execute multiple instructions simultaneously, but due to dependency of instructions, it is often impossible to execute maximum parallel execution. As a result, program contains many NOP instructions. EPIC processor can reduce NOP instructions by changing number of instructions to be executed simultaneously. To implement EPIC type processor, five bit field is embedded in the machine instruction code. For comparison, a 5-stage pipeline processor (basic processor), and a Very Long Instruction Word (VLIW) processor are designed. The proposed processors are described in hardware description language (VHDL) and implemented using FPGA. Operations are confirmed by software Tera Term. Processors are evaluated for instruction parallelism and program size using bubble sort program. It is confirmed that the proposed processor is 1.9 times faster than the basic processor. In addition, the program size of the proposed processor is 64 bytes, the basic processor is 56 bytes, and the VLIW processor is 80 bytes.

  • Flexible manipulator inspired by octopi: advantages of the pulling
    • Abstract: Abstract In this study, we focus on flexible manipulators made of silicone. In conventional works, various flexible manipulators have been proposed. Usually, these manipulators are driven by air pressure. By expanding some parts of a finger, pushing force is generated to bend the finger. In contrast, most real creatures use a pulling force to move their bodies. In our previous works, we developed a flexible manipulator using pulling mechanism that generate octopus-like behavior. However, advantages of the pulling mechanism were not demonstrated enough. In this paper, to confirm the advantages of the proposed pulling mechanism, we develop two manipulators of the same size: one uses the conventional pushing mechanism, and the other uses the proposed pulling mechanism. The goal of this study is to explore the advantages of the developed manipulator with the pulling mechanism by comparing it to the conventional manipulator with the pushing mechanism. Experiments are conducted to compare their adaptive behaviors.

  • Improving controller performance for modeling two-person artificial
           wrestling by underestimating basins of attraction
    • Abstract: Abstract This study proposes a preprocessing method that overcomes the misprediction problems in the intelligent motion controllers (IMCs) of two-person wrestling models. In our previous study, the competitive problems were solved on a coupled inverted pendula model, in which an intelligent controller produced the desired final states by exerting impulsive forces on each pendulum. The final states were inferred from a look-up table (LUT) that stores the dynamic correspondences from the initial to the final states. In a numerical investigation, we demonstrated that the observed performance degradation resulted from mispredictions caused by the limited resolution of the LUT. We conjectured that these mispredictions occur near the basin boundaries of the desirable final states. In the present study, we first derive a simple algorithm that removes the basin boundary points from the LUT. We then show that the resulting controller largely reduces the number of mispredictions, but renders the controller overconservative. We hence propose an adaptive algorithm that removes only the boundary points causing the noted mispredictions. Our second algorithm successfully derives a less conservative controller and improves the overall control performance without increasing the resolution of the LUT, implying that the performance of such a competitive IMC can depend on tiny changes in the a priori knowledge of the system dynamics.

  • Model-based motion control for underwater vehicle-manipulator systems with
           one of the three types of servo subsystems
    • Abstract: Abstract This paper deals with a motion control scheme for underwater robots equipped with manipulators. In general, for each robot, its manipulator is directly driven by electric motors with position sensors such as encoders, whereas its robot body is propelled by marine thrusters with position sensors such as inertial measurement units. It has been pointed out in the literature that for this type of underwater robots, its robot body control is more challenging than its manipulator control, because the robot body has much larger inertia, and many more inaccurate position sensors and actuators than the manipulator. Therefore, it may be practically difficult to accurately control the motion of the robot body, even if an advanced control scheme with good performance is implemented in the controller of the robot body. In this paper, we develop a model-based motion controller for the manipulator under the condition that the robot body is independently controlled by a motion controller with poor performance. Its features are to design the manipulator controller in consideration of the dynamics of the robot body including the marine thrusters as well as those of the manipulator, and to be applicable to underwater robots equipped with one of the three types of servo systems (i.e., a voltage-controlled, a torque-controlled, and a velocity-controlled servo system). Some stability properties of the control system were theoretically ensured in the stability analysis. Furthermore, these results were supported by those obtained in numerical simulations.

  • Relationship between sexual attractiveness and heart rate variability in
           heterosexual men observing photos and self-introduction movies of women
    • Abstract: Abstract In recent years, the problem of declining birthrate has occurred, and how to increase the working-age population has been discussed as a problem to be tackled immediately. The rise in the unmarried rate also contributes to a decline in the birth rate. To solve these problems, you need a way to choose a partner appropriately. In this study, we investigated the relationship between heart rate variability (HRV) and sexual attractiveness while heterosexual men observed the photos and self-introduction movies of women. We measured the indicators of HRV, including low-frequency (LF) and high-frequency (HF) HRV, by computing R–R intervals of the heartbeat waveform. We also demonstrated the time-varying transition of HRV parameters during the self-introduction movies. We found that higher attractiveness evaluation scores were proportional to the transition of LF/HF. The LF/HF value increased when subjects watched videos of females who had been judged as having high attractiveness.

  • The large-scale parallelization of the Boids model on the K computer and
           the heterogeneous multi-processing unit
    • Abstract: Abstract While attempting the parallelization of multiagent systems, a load imbalance often slows down the calculation. Hirokawa et al. presented a multilevel hierarchy of parallelism to mitigate the load-imbalance problem of the Boids model using a pseudo-quadruple arithmetic technique. In this paper, we modify the hierarchies of parallelization for both the K computer and a heterogeneous multiprocessing (HMP) unit, and evaluate the performance of the proposed solutions on these systems. We observed that the parallelization can decrease the negative effects of a load imbalance. Furthermore, we discovered that the power consumption can be effectively controlled by calculating the load and that the simultaneous use of both high-performance cores and low-energy cores slows down the calculations on the HMP unit. Parallelization has been reported to have the potential for enabling the completion of simulations in real time and to have the ability to evaluate up to 3000 billion agents using the K computer.

  • Characteristics of fractal cellular automata constructed from linear rules
    • Abstract: Abstract Cellular automata (CAs) have played a significant role in the study of complex systems. Recently, the recursive estimation of neighbors (REN) algorithm was proposed to extend a CA rule with a unit rule radius to rules with larger radii. This framework enables the construction of non-uniform CAs comprising cells that follow different CA rules. A non-uniform CA, referred to as fractal CA (F-CA), which comprises fractally arranged cells, inherits certain characteristics of basic CAs, including pattern replicability and time-reversibility of linear rules. In this paper, F-CAs based on linear rules, particularly the elementary CA #90 and #150, and life-like CA B1357S1357 and B1357S02468 are investigated. Cells in the F-CAs of #90 and B1357S1357 are separated into groups by their rule radius and each group has an independent lifetime. The explicitly constructed inverse rule of F-CA of #150 is more complex than that of F-CA. The complexity of the F-CA of B1357S02468 and its inverse CA is demonstrated by image scrambling. The F-CAs can be applied to encoding and decoding processes for encryption systems.
