This paper reports an image-based localization for automated vehicle. The proposed method utilizes a mono-camera and a low-cost velocity and inertial sensor to estimate the vehicle pose. Image template matching is applied to provide a correlation distribution between the captured image and a vector structured digital map. A probability of the vehicle pose is then updated using the obtained correlation...
It is extremely difficult for visually impaired people to walk in strange places, because it is extremely challenging for them to know where they are, the direction in which to move, and the destination. Pedestrian navigation systems such as Google Maps have become popular as a result of the evolution and popularization of smartphones and portable tablet devices. However, it is difficult for visually...
It is extremely hard for the visually impaired to walk strange places because it is very difficult to know where they are and the direction to move toward the destination. In addition the existing navigation system is not easy to use for the visually impaired because it is developed for sighted people. In this paper, the pedestrian navigation system for the visually impaired was developed. The high-precision...
It is extremely hard for the visually impaired to walk strange places because it is very difficult to know where they are and the direction to move toward the destination. In addition the existing navigation system is not easy to use for the visually impaired because it is developed for sighted people. In this paper, the pedestrian navigation system called “PullDog” for the visually impaired is developed...
This paper examines the long and short term co-variability of QT and RR intervals for diabetic patients to explore if the QT-RR co-variability could yield a noble index for the stratification of clinical severity of the disease. Twenty four hour Holter ECG recordings are made for 19 type 2 diabetic (T2DM) patients and 25 normal subjects. RR and QT intervals are extracted from ECG signals sampled at...
Owing to huge amount of kinematic energy, ocean current has the potential to be a base power source. However, ocean current power plant has to be submerged in the sea, making it difficult to maintain; therefore it must have high durability and reliability for long-term operation towards utilization. Equipment design approach considers various loads which occur during normal operation of the plant...
This paper investigates the pitch estimation and the instrument recognition of music signals. A note exemplar is a spectrum segment of notes of the specific pitch and instrument, which is stored as a form of dictionary preliminarily. We describe the method of reconstructing a frame of musical signals as the linear combination of exemplars from the large exemplar dictionary with sparse (l1 minimized)...
This paper examines the feasibility of the trend covariability between QT and RR Intervals (QTIs and RRIs) be a novel mean of the sudden cardiac death (SCD) risk stratification. Twenty four hour beat to beat QTIs and RRIs are measured from Holter ECG recordings of 25 normal control subjects (SCD-C), 14 low SCD risk patients (SCD-L) with high blood pressure or light cardiac arrhythmia and 11 SCD high...
In recent years advanced robotic technology has seen increasing use in the medical field to assist in the development of efficient training systems. Such training systems must fulfill the following criteria: they must provide quantitative information, simulate the real-world conditions of the task, and assure training effectiveness. For these reasons, we have developed the Waseda Kyotokagaku Airway...

Many patients suffer from swallowing disorders (dysphagia). There are many treatments for these disorders, such as swallowing therapy, surgery, and dietary modification. In our study, we focuse on dietary modification, a common approach. Normally, the swallowing is affected by food bolus properties such as hardness, stickiness and rheological characteristics, and dietary modifications can prevent...
