Journal of Japan Logistics Society, (22) 213-220, May, 2014 Peer-reviewedWe investigated the following three important issues after the Great East Japan Earthquake: (1) the logistics of relief supplies to the disaster area, (2) the recovery process of transportation, and (3) the corporate structure of the insurance company. Based on these results, we consider the applicability of “the logistics of emergency relief supplies,” which the insurance company can offer as a new service to assist in the early disaster recovery after an earthquake.

NTT Technical Review, 1(9) 19-26, Dec, 2003We have developed an asset tracking system using long-life active RFID (radio frequency identifica-tion) tags that reports the position of an asset when required. To determine the location of a tag attachedto an asset indoors, such as in stores, warehouses, and offices, we use a high-precision location systemthat is not greatly affected by environmental factors. Experimental results show that the root-mean-square error between the estimated and actual tag positions measured at 77 points is 2.9 m, indicatingthat this locating system is applicable not only to asset tracking but also to other ubiquitous services thatutilize the position of an item or a person indoors.

NTT Technical Review, 1(4) 31-39, Jul, 2003In a software-defined radio, the RF (Radio-Frequency) front-end must cope with multi-band radio sig-nals. Therefore, we developed a wideband RF chipset for multi-band direct conversion transceivers. Thechipset consists of a wideband quadrature mixer, a wideband low-noise variable-gain amplifier(LNVGA), and a multi-band local oscillator. The mixer achieves its wideband performance through theincorporation of newly developed power dividers. The LNVGA attains its wideband performance with-out the use of reactance elements. It also has high linearity due to a feedback circuit using two anti-seriesfield-effect transistors. The local oscillator is able to cover the frequency bands of three systems, includ-ing a frequency-division duplexing system, while using only two voltage-controlled oscillators.

John Wiley & Sons, Inc., Mar, 2005 (ISBN: 9780471270539)RF and Microwave Engineering is one of the fastest growth areas of the past decade and will probably continue to be a very active area of research and application in a large variety of fields. The six volume set of Encyclopedia of RF and Microwave Engineering illustrates how this field has been the key to enabling technology responsible for the phenomenal growth of wireless communications. This set also examines how RF and microwave engineering continues to have great influence as the technology behind such important applications as radar, remote sensing, remote control, sensors, navigation, surveillance, electronic warfare, radiometers, plasma research, and imaging.
