In this paper, we proposed an occupant detection system using single video camera and a distance sensor for an advanced airbag deployment. We detected occupant face using skin color and motion information in real time. The proposed method acquired the color and size of the occupant face using single video camera and calculated the distance information between the occupant and airbag using a dis...

Japanese space agencies are planning SELENE mission series, that will launch an orbiter and a lander mission to the moon in the next decade. One of candidates in SELENE 2 missions is a rover mission. A manipulator has strong possibility to be one of equipments mounted on a rover, though. It is to be a periscope and a sampling tool, and can operate other scientific equipments. In this paper, we ...

in [1] we uniquely introduced ultra exponential functions (uxpa) and de nednext step of the serial binary operations: addition, multiplication and power.also, we exhibited the topic of limit summability of real functions in [2,3]. inthis paper, we study limit summability of the ultra exponential functions andprove some of their properties. finally, we pose an unsolved problem aboutthem.

A crop height model (CHM) can be an important element of the decision making process in agriculture, because it relates well with many agronomic parameters, e.g., crop height, plant biomass or crop yield. Today, CHMs can be inexpensively obtained from overlapping imagery captured from unmanned aerial vehicle (UAV) platforms or from proximal sensors attached to ground-based vehicles used for reg...

A system which performs task-oriented navigation for an intelligent mobile robot is described in this paper. This navigation system is based on a dynamically maintained model of the local environment, called the "Composite Local Model." The Composite Local Model integrates information from a rotating sonar sensor, the robot's touch sensor and a pre-learned Global Model as the robot moves throug...

PURPOSE To compare the performance of sonic phacoemulsification with that of ultrasonic phacoemulsification in regard to 1-day postoperative visual acuity, corneal edema, and procedure efficiency. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS This prospective nonrandomized study comprised 86 eyes with mild to moderate nuclear sclerotic cataract. Forty-three eyes had sonic and 4...

Railway infrastructure managers must decide when and how to maintain rails. However, they often have insufficient information about railhead cracks. Therefore, we propose a new method for rail crack detection using train-mounted digital image correlation (DIC) camera system. The measurement train’s weight cause bending, allowing the DIC measure strain concentrations caused by surface-breaking I...
