概要:
This study records six Mantodea species from several islands in the Miyako Islands, including first records from some is

lands. Of the six Mantodea species, four species, i.e. Statilia nemoralis (Saussure, 1870), Tenodera fasciata (Olivier, 1792), T. angustipennis Saussure, 1869 and Hierodula patellifera (Audinet-Serville, 1839), are newly recorded from some adjacent islands of Miyako-jima Island, and two species, i.e. Mantis religiosa (Linnaeus, 1758) and Amantis nawai (Shiraki, 1908), were collected from previously recorded islands in the Miyako Is. Mantis religiosa and T. fasciata were primarily observed in open grasslands, and in contrast, T. angustipennis was mainly found around forest edges on Tarama-jima I. Few nymphs and an ootheca of S. nemoralis were found in grasslands on Ikema-jima I. and Kurima-jima I. Hierodula patellifera was the most abundant among mantis species during these surveys; a number of adults and a few nymphs of this species were observed in our expedition. For Amantis nawai, specimens of only the adult stage were observed, on the dried leaf litter of the forest floor on Miyako-jima I. In addition, three Mantodea species, M. religiosa, T. angustipennis and H. patellifera, were collected from UV-LED light trap set as a counterplan against Anomala albopilosa (Hope, 1839) (Coleoptera: Scarabaeidae) on Tarama-jima I.

てアンテナパターン多重 (Antenna Pattern Multiplexing; APM) 技術に着目して研究を行ってきた．本稿では，APMの原理について時変指向性利得として，周波数分割多重および符号分割多重に基づく周期波形を用いて説明を試み，単一のアンテナ系統から，複数の分離可能なアンテナ出力が得られることを示す．
We have been studied Antenna Pattern Multiplexing (APM) technique suitable for receivers of Single-Input Multiple-Output (SIMO), Multiple-Input Multiple-Output (MIMO), and massive MIMO systems. APM technique has potential to reduce the hardware cost of the receivers, for example, size of antenna, the number of required cables, cabling cost, calibration cost, maintenance cost, etc. In this paper, we try to explain the principle of APM with time-variable directional gain designed based on Frequency Division Multiplexing (FDM) and Code Division Multiplexing (CDM). Through the paper, we show how to obtain multiple distinguishable antenna outputs from a single Radio Frequency (RF) front-end. 論文 続きを見る |
