Background： Hypoxia tolerance studies in cotton are very rare in Pakistan. Unpredicted and excessive rainfalls result in severe losses to cotton crop in many regions of the country due to lack of hypoxia tolerance in current cotton varieties. The genotypes that can tolerate flooding are not reported earlier. The studies were conducted to explore hypoxia tolerance in local germplasm which will help to develop hypoxia tolerant cotton varieties. Method： An experiment with randomized complete different cotton varieties. The genotypes were given conditions. blocks was designed to study the hypoxia tolerance in two treatments i.e., water logged and non-water logged Results： The genotypes showed significant variability for yield, fiber and physiological traits. The hypoxia studies revealed that there is significant reduction for plant height in water sensitive genotype LRA-5166. The genotype MNH-786 showed better yield and MNH-556 showed superior ginning outturn percentage under water logged conditions. Staple length, strength and micronaire values also decreased under hypoxia. Similar pattern of negative effects were observed for Chlorophyll a, b contents and chl a/b ratio. Two hypoxia tolerant cultivars CIM-573 and MNH-564 had significantly higher chlorophyll a （1.664, 1.551） than other cultivars under both normal and waterlogged conditions. There was a significant decrease in total free amino acids in all genotypes/cultivars due to waterlogging. Free amino acid contents were significantly higher in two waterlogging sensitive cultivars, CEDIX and N-KRISHMA, than other cultivars under both non-waterlogged and waterlogged conditions. Waterlogging caused a significant reduction in shoot soluble proteins and increase in shoot proline. The genotype LRA-5166 was the highest in shoot soluble proteins content and showed significant decrease in shoot proline. Conclusions： With respect to yield MNH-786 showed better results and regarding ginning outturn percentage MNH-556 exhibite

Four-dimensional parameter estimation of plane waves using swarming intelligence

引用

Chinese Physics B 2014年第7期23卷 754-761页

作者： Fawad Zaman Ijaz Mansoor Qureshi Fahad Munir zafar ullah Khan Department of Electronic Engineering Faculty of Engineering and Technology International Islamic University Sector H-10 Department of Electrical Engineering Air University

This paper proposes an efficient approach for four-dimensional （4D） parameter estimation of plane waves impinging on a 2-L shape array. The 4D parameters include amplitude, frequency and the two-dimensional （2D） direction of arrival, namely, azimuth and elevation angles. The proposed approach is based on memetic computation, in which the global optimizer, particle swarm optimization is hybridized with a rapid local search technique, pattern search. For this purpose, a new multi-objective fitness function is used. This fitness function is the combination of mean square error and the correlation between the normalized desired and estimated vectors. The proposed hybrid scheme is not only compared with individual performances of particle swarm optimization and pattern search, but also with the performance of the hybrid genetic algorithm and that of the traditional approach. A large number of Monte-Carlo simulations are carried out to validate the performance of the proposed scheme. It gives promising results in terms of estimation accuracy, convergence rate, proximity effect and robustness against noise.

采用不同烧结工艺制备新型Al/Cu Fe多层核壳颗粒增强铝基复合材料(AMCs),研究其对显微组织和力学性能的影响。分别采用电置换法和化学镀法在铝粉颗粒上沉积Cu层和Fe层,制备多层Al/Cu Fe核壳颗粒。采用X射线衍射(XRD)、扫描电子显微镜(SEM)/能谱(EDX)、密度计、显微硬度和压缩试验等方法对复合材料进行表征。结果表明,在放电等离子烧结复合材料中,由于沉积层向金属间化合物相转变,界面反应程度提高,复合材料的相对密度(99.26%)、显微硬度(165 HV0.3)和强度(572 MPa)均显著提高。此外,热压复合材料壳层结构中存在的未转化Cu导致其断裂应变最高(20.4%)。研究结果对通过选择合适的烧结路径来调整AMCs的显微组织和控制其力学性能具有重要意义。
