Toward realization of “writing-life-log,” a camera-based handwriting pattern acquisition system is proposed. The camera is attached around the tip of a popular pen and captures frame images around the pen tip continuously. Our problem is the reconstruction of the entire handwriting pattern by video-mosaicing of those frame images with perspective(More)
This paper presents a method to generate car-following patterns for individual drivers. We assume that driving is a recursive process. A driver recognizes a road environment such as velocity and following distance and adjusts gas and brake pedal positions. A vehicle status changes according to the driver's operation and the road environment changes(More)
A chemical synthesis of 2-deoxyribose-1-phosphate 2 and its enzymatic conversion into purine 2'-deoxynucleosides (dNus) are shown. Besides the chemo-enzymatic process for purine dNus, a modified process for practical dC preparation is also established. Consequently, a series of practical manufacturing processes of all four dNus have been realized via novel(More)
This paper has proposed the evaluation method of the MIMO antenna performance including frequency characteristics. Since the performance of the MIMO antenna depends on both radiation efficiency and correlation coefficient, the task for evaluating the antenna, especially including frequency characteristic is heavy and time consuming. The effective radiation(More)
