We discuss the dynamical simulation model of the thermal environment for automobile passenger compartments which is useful for the development of automobile air-conditioning systems. In our previous research, we proposed the model of this type considering the accuracy and the amount of computation, however, proposed model was insufficient to simulate the effect of thermal radiation and insolation...
The aim of this study is to generate a standard ship's navigator's decision-making and action model that might become one index for safety navigation and navigational education area. It is important for a navigator to avoid targets and secure a navigation space for the prevention of collision. In this study, a navigator' decision-making and action for avoidance is focused and navigator's decision-making...
Subsurface exploration has been progressing rapidly. Exploring of the subsurface of Earth has received a lot of attention to investigate such environment as volcano, ocean and space. Now advanced technologies are required in subsurface exploration and some countries have tried to meet these new challenges. A subsurface investigation of celestial bodies is regarded as a especially significant technology...
This paper presents the method to determine the optimum values of the capacitance and rotor-slot skew pitch to maximize the efficiency of a single-phase capacitor-run permanent-magnet motor using the time-stepping finite element analysis and response surface methodology. The optimum values of the capacitance and rotor skew pitch to maximize the efficiency at the rated voltage and output are obtained...
This paper presents a new technique for simple, highly accurate calibration of relative position between a robot arm and a target work. This technique can shorten calibration time and reduce production cost. In this study, we adopted point-to-face touching for simple, highly accurate calibration. Point-to-face touching means to touch work surface with one point of an arm tip tool. Robot arms can get...
As space exploration progresses, renewed attention has been given to advanced lunar exploration technologies. The main objective is to address many open questions about the Moon, such as its origin or chemical components, as most of the current hypotheses are just inferences based on limited evidences. Unmanned subsurface investigation technologies for the moon are of special significance for future...
