This paper presents a tool with a light-emitting diode (LED) connected to a piezoelectric ceramic element for directly visualizing an intense ultrasonic field. The piezoelectric element generates electric voltage proportional to the ultrasonic pressure applied to the element; the LED is then turned on by the voltage. The sound pressure is directly observed as light intensity of the LED by human eyes...
An attempt was made to evaluate the Sequential Error Rate (SER) of an SSVEP classification problem with a Bayesian sequential learning algorithm. Sequential Error Rate refers to the average classification error rate windowed over a short trial period. The algorithm was implemented by the Sequential Monte Carlo method. As opposed to the batch learning algorithm, the sequential learning algorithm does...
This paper is focused on the process of value creation in the service business and on the shift of service value created in actual service businesses. The analysis is used to demonstrate proposed models for explaining this shift. Service value is successfully created when customers enjoy the benefits of services proposed through a system of service businesses. The model visualizes the shift of service...
We propose a hierarchical display method for small devices based on saliency. This method displays a large scale image in a small screen of a small mobile device as a mobile phone. In this method a region of interest (ROI) is detected using a saliency model. The region is successively detected hierarchically to produce a tree structure of ROI. Then we calculate the increasing rate of saliency in each...
Today NAND flash memory is used for data and code storage in digital cameras, USB devices, cell phones, camcorders, and solid-state disk drives. To satisfy the market demand for lower cost per bit and higher density nonvolatile memory, in addition to technology scaling, 2 b/cell MLC technology was introduced. Recently MLC NAND flash memories with more than 2 b/cell have been reported. To meet market...
In order to investigate the effect of posture on sound source localization in daily 3D spatial listening, we performed a sound source localization test in the front-middle (vertical) plane. This test systematically controlled the subject's body angle and the relative position between the eye level and the center of the sound source position. The test was conducted for three eye-positional conditions,...
Modular visualization environments (MVEs) have recently been regarded as the de facto standard for scientific data visualization, mainly due to adoption of the visual programming style, reusability, and extendability. However, since scientists and engineers as the MVE principal user are not always familiar with how to map numerical data to proper graphical primitives, the set of built-in modules is...
