EV at anytime for security. This study investigates an appropriate allocation of EV rechargers

in Musashino city. We define the priority orderamong EV recharger candidates by comparing
with a Voronoi diagram and the priority ordercircular diagram. Both diagrams are represented
by the segmentation from specific town information.

The outcome of this approach will result ina blueprint for implementing infrastructure to

ions can be accelerated from the surface into thebulk by the electric field with the negative bias.

The possibility of the H+ ions in the bulk siliconhas been predicted in the previous reports. The

and a single CCD camera that is mounted on theend-effector. This robot is a typical example of aneye-in-hand system with a single camera. The
control objective is to keep the target object

The ANN model used energy cepstral coefficients obtained by filter banks based onhuman auditory characteristics as input par-ameters representing a spectral feature of asound signal. Subsequently, an output of thisANN model and a filtered envelope of the signal

were used for making an input sequence for the
HMM that deals with the temporal variation of
the sound signal. Compared with the convention-

the proposed hybrid model improved recognition
