Outage Capacity Analysis for Cooperative DF and AF Relaying in Dissimilar Rayleigh Fading Channels
스레스타,장경희,Shrestha, Suchitra,Chang, Kyung-Hi The Korea Institute of Information and Commucation 2008 韓國通信學會論文誌 Vol.33 No.4A
Cooperative relaying permits one or more relay to transmit a signal from the source to the destination, thereby increasing network coverage and spectral efficiency. The performance of cooperative relaying is often measured as outage probability. However, appropriate measure for the channel quality is outage capacity. Although the outage probability for cooperative relaying protocol has been analyzed before, very little research has been addressed for the outage capacity. This paper is the first of its kind to derive a closed-form analytical solution of outage capacity using fixed decode and forward relaying and amplify and forward relaying in dissimilar Rayleigh fading channels, considering channel coefficients known to the receiver side. The analytical results show a tradeoff between the SNR and the number of relays for specific outage capacity. A comparison between decode and forward relaying and amplify and forward relaying shows that decode and forward relaying outperforms amplify and forward relaying for a large number of relays.

The paper briefly reviews the main activities of Nepal concerning with the conservation of plant genetic resources, with special reference to forestry. Some recent developments in the field of genetic resource conservation are examined in a historical perspective, focusing on continuing programs, trends, and needs in the field of plant genetic resources. The conservation of primitive cultivars and of the wild relatives of our domesticated plants has become an urgent problem of very great importance for the continuing productivity of cultivated plants. The main centers of genetic diversity are situated in the developing countries of Asia, Africa, and Latin America, where rapid agricultural and other development is threatening the continued existence of these ancient plant populations. Measures which should be taken without delay include a rapid inventory of genetic resources in the field and in existing collections, protection in situ of threatened and important wild communities, and conservation of primitive cultivars in collections and, wherever possible, in long-term seed storage.

식물성장촉진 뿌리박테리아(PGPR)을 사용한 생물학적 조절(Biological control)은 최근 몇년 동안에 주목 받게되었다. PGPR은 산업적으로 중요한 감자, 토마토 그리고 쌀과 같은 경제적으로 중요한 작물의 성장촉진과 관련되어있다. 음식물 쓰레기에서 발견된 Bacillus mojavensis KJS-3은 Aspergillus terreus, A. fumagatus, A. flavus and Fusarium redolense에 대해 항진균작용을 가지고 있는 균주로, 이미 여러 산업적인 측면에서 유용한 가능성이 확인된 균주이다. 본 연구에서는 Bacillus mojavensis KJS-3를 알타리무와 상추에 0.5×10<SUP>9</SUP> cfu/g, 1.0×10<SUP>9</SUP> cfu/g 및 2.0×10<SUP>9</SUP> cfu/g의 3가지 농도로 분무, 재배한 후, 잎의 수, 길이, 무게, 뿌리와 근경의 길이, 넓이 및 무게를 비교함으로써, 이들에 대한 생육촉진작용을 확인해보았다. 그 결과, 처리하지 않은 군에 비하여 Bacillus mojavensis KJS-3를 처리한 군이 더 높은 생육성장을 보였으며, 1.0×10<SUP>9</SUP> cfu/g농도에서의 재배는 저농도에서의 재배보다 더 높은 생육성장을 그리고 고농도에서의 재배와 비슷한 생육성장을 나타내었다. 이러한 결과를 토대로 B. mojavensis KJS-3의 생물학적 비료로서의 가능성을 확인할 수 있었으며, 또한 B. mojavensis KJS-3의 다른 작물에 대한 생육조절제의 적용도 가능할 것으로 예상된다. Biological control using the plant growth-promoting Rhizobacterium (PGPR) has received significant attention in recent years. PGPR has been linked with promoting growth in economically important crops, such as potatoes, tomatoes, and rice. Bacillus mojavensis KJS-3 (Moja-3), isolated from food waste, possesses antifungal properties against Aspergillus terreus, A. fumagatus, A. flavus, and Fusarium redolense, and it may have potential in the development of products for industrial applications. The main purpose of this study was to determine the effects of spraying the PGPR Bacillus mojavensis KJS-3 on the growth of altari radish (leaf number, leaf length, leaf weight, root length, and rhizome length, adjacent portion diameter, and weight) and lettuce (leaf number, length, width, and weight). Three different concentrations of the foliar spray treatment of B. mojavensis KJS-3 were applied to the altari radish and lettuce: the recommended standard concentration of 1×10<SUP>9</SUP> cfu/g, half the standard concentration of 0.5×10<SUP>9</SUP> cfu/g, and double the standard concentration of 2×10<SUP>9</SUP> cfu/g). The B. mojavensis strain foliar spray treatment increased the growth of the leaves and roots of the altari radish and increased the growth of the lettuce leaves. For both plants, the recommended concentration of B. mojavensis KJS-3 produced better growth than half the standard concentration, and the growth was similar with the double dose. This study demonstrates positive effects of Moja-3, suggesting it may be a potential new bio-fertilizer for improving the growth of altari radish and lettuce.
