In 2001, Pyricularia oryzae isolates, showing reduced sensitivity to scytalone dehydratase inhibitors, were collected from the Matsuura river area in Saga prefecture, Japan. A single-point mutation causing substitution of one amino acid in scytalone dehydratase was found in those isolates. However, the blast control efficacy of carpropamid in the field has not been completely lost in the area where...
Pulsed streamer discharge plasma which is one of the non-thermal plasmas has been used to generate ozone and to treat exhaust gases. In our previous studies, it is found that a pulse duration of applied voltage has a strong influence on the energy efficiency of exhaust gas treatment and ozone generation. Therefore the development of a shorter pulse generator is of paramount importance for practical...
In the small brushless DC motor, the system in which the unidirectional current flows can be adopted. However, recently, the brushless DC motor, in which the bidirectional current flows, is being mainly studied. The unidirectional motor system is easy to control the direction of the torque by all armature windings. Considering the above fact, we developed the highly effective brushless DC motor, in...
Due to people!s concern for a healthy life, there is a rising need for a health monitoring available anytime and anywhere. We present an ubiquitous health monitoring system based on the NGN/IMS (next generation network/IP multimedia subsystem) and proper data format design for ubiquitous health monitoring system.
In this demonstration we present an ubiquitous health monitoring system based on the NGN/IMS (next generation network/IP multimedia subsystem). It enables us to be taken care of by medical professionals anytime, anywhere using portable medical sensors and mobile networks. To provide seamless health monitoring services, an open, secure and functional platform is required. Such a platform should support...
A 0.13 mum CMOS Cartesian loop transmitter IC with calibration and loop setting scheme of less than 5 mus is fabricated in order to keep high efficiency in wide output power range. The proposed scheme adjusts amplitude, phase, loop gain by using TX modulated signal for fast loop setting. Adjacent channel power leakage ratio (ACPR) is improved by 18 dB. The transmitter IC without PA consumes 62 mA,...
In this paper, a single-chip dual-mode 8-band 130 nm CMOS transceiver including A/D/A converters and digital filters with 312 MHz LVDS interface is presented. For a transmitter chain, linear direct quadrature modulation architecture is introduced for both W-CDMA/HSDPA (high speed uplink packet access) and for GSM/EDGE. Analog baseband LPFs and quadrature modulators are commonly used both for GSM and...
This paper presents an approach to the problem of community data management in the IP multimedia subsystem (IMS) environment. More specifically, it describes a framework of the community management with the use of object deputy data model, which is developed as a key component of the enhanced platform for IMS to provide group-centric, media-rich interactive services. Furthermore, on the basis of data...
The sensor networks had been used for various application areas and showed effectiveness under the prior application planning and right circumstances that includes cost, data handling and other resources. In order to generalize, it is required to reduce initial cost and use data effectively. This paper proposes connecting a sensor network with the IMS that is the service platform of the NGN to solve...
This paper proposes two approaches for reducing carsickness while watching an onboard display in a vehicle. The approaches are based on the sensory conflict theory to reduce a conflict of sensory information between the vestibular and the visual systems. Visual stimulus along with the original content is presented on the onboard display to provide optokinetic sensation of yaw rotation of a vehicle...
A 5 GHz MIMO direct-conversion transceiver composed of 2 transmitters (TXs) and 3 receivers (RXs) is fabricated with 0.13 mum CMOS technology. Die size is 4.56 mm times 7.7 mm. For driving 10 GHz LO signal lines of 5 mm length for both TXs and RXs, inductor-less low-power LO repeaters are equipped in individual LO paths. A linearized RF variable gain amplifier is proposed for low power operation....
The authors explore a new laboratory learning system for the simultaneous measurement of some environmental conditions such as temperature, noise and light by using wireless LAN system in a wide range of areas. The system contains a Control PC and Control Module which is comprised of voltage supply, communication part and measuring module. This research intends to develop software which controls the...
