Our novel multi-view display is based on the “Quantized-Diffusion-Angle screen (QSA Screen).” We believe that the multi-view screen brings high tele-presence to teleconference systems because it accurately reproduces head direction, one of the essential modalities for teleconference systems. This paper proposes a short projection method to eliminate the weakness of the QDA screen when applied to teleconference...
We present a speaker clustering method for conversational speech recordings that contain short utterances from multiple speakers. The proposed method represents a speech segment with a vector of VQ code frequencies and uses a cosine between two vectors as their similarity measure. The clustering is performed by a spectral clustering algorithm with cluster number estimation based on an eigen structure...
This study estimates the economic impact of local tourist spending through its multiplier effect and develops a method to estimate the ideal economic scale of local tourist industry. We conducted quarterly survey of tourist spending in Yuri, Akita during 2006. Using survey data, we first estimate the actual scale of tourist industry in Yuri, and find that it is approximately 20 billion. Further, we...
This paper reports the design, fabrication, and experimental results for a micro channel array (MCA)-based photodynamic cell perforator toward intracellular technology. The perforator will be developed to improve whole-cell patch-clamp technique. The perforator consists of planar micro channels and electrodes of the MCA. The perforator utilizes the micro channel for both cell suction and chemical...
Cases of primary spinal epidural Extra-osseous Ewings sarcoma (EES) are rarely seen and a good prognosis for EES cannot be expected since a high incidence of local recurrence and metastasis frequently occur. We present a case of cervical spinal epidural EES in a 7-year-old girl with long survival after tumour resection. She also received adjuvant treatment with peripheral blood stem cell transplantation...
