Computer-aided detection/diagnosis (CAD) is emerging as an innovative interdisciplinary technology for medical service. The traditional concept of automated computer diagnosis is encountered with a significant barrier because computerized medical systems cannot fully replace human doctors with the comparable level of performance. By contrast, CAD is becoming widely adopted in clinical work because...
Realization of a high frequency resonator for 3.6 GHz-band filter in the International Mobile Telecommunication Advanced (IMT-Advanced) system is desired. It is difficult to accomplish such a high frequency resonator using conventional surface acoustic wave (SAW) technology, because the strip width of the inter-digital transducers (IDT) becomes too narrow. Although anti-symmetry 1st (A1) mode Lamb...
We have improved ELK film so that it is suitable for the processes used in fabricating Cu interconnects without using a dielectric protection layer for CMP, the so called “direct CMP process”. The depth profile of the pore size in the film was successfully controlled to prevent water absorption during the CMP process with a limited k-value increase in the film. The line-to-line dielectric breakdown...
In this paper, we deal with the kind of distributed embedded software that is constructed from tasks that communicate with each other by sending and receiving multicast messages. These tasks must share resources. So, it is important to schedule a timetable describing when the tasks occupy the resources so that there is no resource competition and the tasks occupy the resources within pre-specified...
Small sized surface acoustic wave (SAW) duplexer for wide band code division multiple access (W- CDMA) system with a good temperature coefficient of frequency (TCF) and good frequency characteristics has been required. However, the size of conventional SAW duplexer for W-CDMA using Al-electrode/50-70degYX- LiNbO3 is large (3.8x3.8 mm2) and its TCF is not good (-80ppm/degC). So, this duplexer can't...
In this paper, the three-dimensional driving simulator (DS) using CAVE, which enables us to provide three-dimensional visual information, is developed. The developed DS is used to analyze the collision avoidance behavior characterized by the braking and steering operations at the instance of the sudden stopping of the preceding vehicle. A group method of data handling (GMDH) is applied to the measured...
