There are many systems to include humans in the mechanical control loops. In such systems, low-skilled operators are considered to cause accidents. To prevent these kinds of accidents, analysis of human's model with various methods has been studied. “Crossover model” is well known as one of the models to analyze human-machine systems. However, many of those researches have analyzed humans when they...
Physiome and systems biology have been recognized as emerging and important research areas that can integrate quantitatively growing knowledge about biological structure and physiological functions at multiple scales of time and space. For the integration, it is important to build physiologically plausible and sharable mathematical models that can be used for dynamic simulations of functions at multi-scale...
If robot systems are being deployed in real world settings with untrained users who happen to accidentally pass by or could leave at any moment in time, then this places specific demands on the robot system: it needs to secure and maintain the user's engagement. In this, a common and critical problem consists of entering into a `focused encounter'. It requires each interactional partner to closely...
This paper proposes perceptual segmentation of natural color images using a fuzzy-based hierarchical algorithm and its application to the segmentation of dermoscopy images. A fuzzy-based homogeneity measure makes a fusion of the color features and the texture features. The proposed hierarchical segmentation method is performed in four stages: simple splitting, local merging, global merging and boundary...
An adhesion-based cell-separation device is developed for the extraction of rare cells from a cell mixture. The cell-separation principle mimics leukocyte recruitment from blood vessels in our body, where leukocytes are decelerated by antigen-antibody interaction at the sites of inflammation or injury. Separation of cell mixture can be accomplished by simply introducing the sample plug through an...
We studied smooth path planning using predesigned steering sets including three trajectory types. Path planning with a steering set is used to generate trajectories with smooth changes in direction. To put our path planning to practical use in dynamic environments, it needs to detect the movement of humans and to avoid moving humans. It is important that robot motion is fast and efficient, while also...
The purpose of this study is to determine what factors influence short-term memory, for a short time that may or may not equal the presentation time. Six or seven English characters are presented for a short time sequentially and at the same position on the display of a CRT. A masking stimulus is presented along with the characters. It is found that: (1) The total presentation time, which is the sum...
