Designing auto-pilot using actual ship was effective educational program for students. However, there was a lot of difficulty on the actual ship experiment for students. In this paper, to overcome the problem, ship simulator system for designing auto-pilot was proposed.
This paper propose a biometric personal identification method based on a pair of right and left sole pressure distribution change. We acquire the sole pressure distribution change by load distribution sensor and use it for a personal identification. We employ twelve features based on shape of footprint, and twenty seven features based on movement of weight during walking for each sole pressure data...
The individual neurons encode information as spiking trains. But the spiking trains all together also reveal synchronizations like alpha (~ 10 Hz) and gamma (~ 40 Hz) rhythms. These high frequency rhythms, in contrast to those of low frequency observed from fMRI on the resting state of the brain, are measured on the external environment with explicit tasks. Analyses of fMRI data have revealed functionally...
A navigator efforts to guide a ship for safe navigation, and s/he gets a navigational information through five senses. Visual information is most important because it is said to occupy eighty percents to whole information. We are researching on relationship between a visual image of seascape and a physiological and a body response using ship bridge simulator, which is used to train and educate ship...
This paper describes a method for distribution of people monitoring system using a 3D camera. This camera measures distance and intensity distribution based on time of flight (TOF). From the obtained distance data, we perform clustering processing to detect the distribution of people. In our method, fuzzy logic plays a primary role to decide the cluster, i.e., people number. Our proposed method applied...
An integrated evaluation system for acid-base balance is proposed based on laboratory results in medical practice. It provides degree of each disorder type in acid-base disorder based on fuzzy inference and the reason of each disorder with laboratory results except blood gas test. Evaluation experimental results for 11936 data taken in clinical laboratory of Kochi Medical School Hospital show that...
In the ship handling simulator using virtual visual system, it might be difficult for a young trainee to attend with the tension. In this paper, to overcome the problem, the ship handling simulator using actual training ship was proposed. The ship handling simulator was achieved by developing the control system which reproduced a large vessel's maneuverability on the actual training ship.
Various types of robots have been applied to the fields of education. Students can learn the interdisciplinary knowledge on mechanics, electronics, dynamics, biology, and informatics with robots, or called Learning through Robots. An educational robot is designed for students to learn mathematics, physics and mechanics. In order to conduct robot edutainment, some experiments are performed in junior...
The study conducted in this work analyses the interactions between different Evolutionary Algorithms when they are hybridized. For this purpose, the phylogenetic tree of the best solution reported by the hybrid algorithm is reconstructed, and the relationships among the ancestors of this solution are established. For each of these ancestors, the evolutionary techniques that generated that solution...
Proportional-Integral-Derivative (PID) control has been most commonly used to operate mechanical systems. In PID control, however, there are limits to the accuracy of the resulting movement because of the influence of gravity, friction, and interaction of joints. In contrast, digital acceleration control (DAC) is robust against these modeling errors by nonlinear terms. DAC requires information of...
The Channel Theory have been used to represent information flows qualitatively. Chu maps are often utilized for showing classifications in the Channel Theory. This framework is very useful and Chu maps have been used for interface design. This framework has a difficulty such that the domain knowledge represented in this framework is static. That is, there is no way to modify existing domain knowledge...
In this paper a Fuzzy Logic Control (FLC) will be developed to stabilize and control a fixed-wing unmanned aerial vehicle (UAV). The development, simulation and implementation of the control are the main objectives. The FLC must be able to direct the airplane towards different waypoints while at the same time maintaining the UAV stable.
Data assimilation is an advanced and innovative set of techniques for variable estimation, especially in agriculture research in recent years, which integrates not only remote sensing data products, other measurements, but also land dynamic models. It can provide more abundant and precise data set, and extend data's spatiotemporal scale. In this paper, firstly composition and assimilation methods...
The main concern of this paper was to establish the force model of seeds motion during the sucking process and to find different factors impacting seeds suction performance. Then the mathematical model of forces acting on seeds during the sucking process was established in order to optimize the working parameters including the sucking force F, the rotational speed of cylinder ω and the position angle...
Objective: The outbreak of animal infectious diseases directly affects the economic benefits of livestock and poultry production, and even threatens the safety of human life. And due to the specificity of livestock and poultry production, the infectious diseases will be difficult to control by medical treatment means when outbreak in groups. Knowing the outbreak and development of infectious diseases...
Objective: The mathematical model prediction has been widely recognized among many disease forecasting methods. But different models will show out distinct prediction results of different diseases, as well as their occurrence locations. In this study, ARMA, exponential smoothing and seasonal index model were adopted for predicting incidence of Newcastle disease, and evaluating the precision of these...
Maize dwarf mosaic (MDM) is an important maize viral disease in the world. Disease forecast plays a vital role in controlling it. In this study, three growth models including Logistic growth model, Gompertz model and Weibull model, were used to fit seven groups of MDM data obtained in Chengde, Hebei Province in China. Residual sum of square test showed that Gompertz model had the smallest residual...
Soybean root is one of the most important organs of soybean. It takes important effect on the growth and development, physiological function and metabolism of the soybean. Because of the particularity of the root growth environment, it makes the study of root crops far lagging behind that on the ground. Virtual plant overcomes the disadvantages of taking a long time on experiment and other environmental...
In this study, 56 ECa profiles, which inversed by the EM38 linear model with Tikhonov regularization method, were selected as the original datum of 3D variation. The spatial variability of ECa at ten depths was simulated by the SGS method. It was shown that not only the spatial distribution characteristics of the original data, but also the volatility of the distribution was well simulated by the...
Water test was got in 2007. Controling the soil moisture content in yield forming stage. According to the analysis of the classical growth theory, established a peanut growth model under control the soil water. The model was studies by using one peanut cultivar Fenghua 1. A peanut pool-culture experiment under control of rain protection shed was carried out to keep relative soil water content of 0-30cm...
