Height-latitude structure of stationary planetary waves in the stratosphere and lower mesosphere

Daily UK Met Office stratospheric assimilated data for the Northern and Southern Hemispheres, accumulated for the period from 2004 to 2012 and pressure range of 1000–0.1 hPa, are used in this paper. The paper presents and thoroughly discusses spatial–temporal distributions of stationary planetary wave (SPW) amplitudes and phases, calculated on the basis of geopotential height, temperature, zonal and meridional wind data for zonal wave numbers 1 and 2 (SPW1 and SPW2). The climatological planetary wave amplitudes and phases are calculated by extracting waves from three types of data: daily, monthly mean and climatological monthly mean. It has been established that magnitude of amplitudes and height-latitude distribution of amplitudes of SPW1 and SPW2 depend on data processing method for all parameters. It has also been established that height-latitude distribution amplitudes and phases significantly differ for geopotential height, temperature, zonal and meridional wind and depend on wave number and hemisphere. However, height-latitude distributions of phases are little different from each other for the used methods of data processing.     

Planetary protection on international waters: An onboard protocol for capsule retrieval and biosafety control in sample return mission

Planetary protection has been recognized as one of the most important issues in sample return missions that may host certain living forms and biotic signatures in a returned sample. This paper proposes an initiative of sample capsule retrieval and onboard biosafety protocol in international waters for future biological and organic constituent missions to bring samples from possible habitable bodies in the solar system. We suggest the advantages of international waters being outside of national jurisdiction and active regions of human and traffic affairs on the condition that we accept the Outer Space Treaty. The scheme of onboard biological quarantine definitely reduces the potential risk of back-contamination of extraterrestrial materials to the Earth.     

Detection and mapping vegetation cover based on the Spectral Angle Mapper algorithm using NOAA AVHRR data

Satellite data, taken from the National Oceanic and Atmospheric Administration (NOAA) have been proposed and used for the detection and the cartography of vegetation cover in North Africa. The data used were acquired at the Analysis and Application of Radiation Laboratory (LAAR) from the Advanced Very High Resolution Radiometer (AVHRR) sensor of 1 km spatial resolution. The Spectral Angle Mapper Algorithm (SAM) is used for the classification of many studies using high resolution satellite data. In the present paper, we propose to apply the SAM algorithm to the moderate resolution of the NOAA AVHRR sensor data for classifying the vegetation cover. This study allows also exploiting other classification methods for the low resolution. First, the normalized difference vegetation index (NDVI) is extracted from two channels 1 and 2 of the AVHRR sensor. In order to obtain an initial density representation of vegetal formation distribution, a methodology, based on the combination between the threshold method and the decision tree, is used. This combination is carried out due to the lack of accurate data related to the thresholds that delimit each class. In a second time, and based on spectral behavior, a vegetation cover map is developed using SAM algorithm. Finally, with the use of low resolution satellite images (NOAA AVHRR) and with only two channels, it is possible to identify the most dominant species in North Africa such as: forests of the Liege oaks, other forests, cereal’s cultivation, steppes and bar soil.     

Asteroid and comet hazard: Identification problem of observed space objects with the parental bodies

This article focuses on the genetic identification of observed small cosmic bodies with alleged parental bodies; namely, comets, asteroids and meteoroid swarms. There is a problem of the upper D-value limit as a measure of proximity between the orbits of the bodies in the five-dimensional phase space (Southworth and Hawkins, 1963). In the study of genetic relationships of the comet and meteor complexes, the D value is usually taken as equal to 0.2 for all meteor showers. However, the upper D limit should be investigated for each meteoroid complex. For example, such investigation was performed for the Taurid meteor complex (Porub?an et al., 2006). In this paper, the upper D-criterion limit value was investigated for the Perseid meteor shower. The 1862 III Swift–Tuttle comet is its parental comet.     

当前经济增长的周期性、阶段性特征及政策思路

根据经济周期谷底的特性以及中美两国经济紧密关联和经济周期越来越契合的规律,可以印证2009年就是新一轮经济周期的谷底,由此可以断定当前处于复苏阶段.然而近三年来我国经济增速持续下滑至谷底以下,这一反常现象是由于经济短周期冲高回落与经济增长阶段转换相互叠加造成的.河南省与全国经济周期高度一致,时滞半年左右.在高速经济增长阶段河南省潜在经济增长率比全国高出2个百分点,中高速阶段高出1.5个百分点.河南省近几年经济增速深度下滑,其关键原因是投资增速下滑,其根本原因是结构升级缓慢.未来河南经济要摆脱持续下行趋势,保持经济中高速增长,应坚持调结构、扩投资、促改革的政策思路,“调结构”是根本,“扩投资”是基础,“促改革”是保障.     

权力制约：经典范式、内在逻辑与语境化

实质意义上的权力制约肇始于权力分化之后，历经以道德制约权力、以权力制约权力、以社会制约权力等经典范式，体现了权力制约活动从关注权力执掌者、权力本体到关注权力归属者不断演变的内在逻辑。植根于我国国情的权力制约实践在伦理学、社会学途径方面与西方存有共性，但于政治学途径却存有个性。实现我国权力制约的语境化既需要体现权力制约的普遍性规律，更需要把握马克思主义政治观视域下权力制约的特殊性。     

合肥市会计服务业发展研究

对合肥市会计服务业及其发展进行了研究,研究2009-2013年安徽省（合肥市）会计师事务所数量和注册会计师数量,发现合肥市会计服务业发展形势较为严峻,具体表现为：会计师事务所规模较小,内部治理机制不够完善、业务种类不够全面,管理机制不够健全,人才结构不够合理,高端人才较少,国际化程度不高,并提出合肥市应当加强会计服务行业地方法规政策的完善与制定、提高会计服务业的社会透明度、加强会计服务业的多元化发展、加强业务创新,开创自身特色、加强复合型人才培养,提升会计服务业人员整体素质、推行联合重组,避免内部竞争,以促进会计服务业的进一步发展。     

基于Kriging的多目标遗传算法

为了提高多目标优化问题的求解效率,提出了一种新的处理约束多目标优化问题的基于Kriging的多目标遗传算法(MOKGA)。MOKGA采用物理规划法将多目标优化转化为单目标优化,然后构建目标函数的考虑约束的EI(Expected Improvement)模型,并采用遗传算法进行求解。六峰值驼背函数和一个导弹多目标多学科设计优化问题用于MOKGA算法性能的测试。结果表明,与理论解相比,MOKGA算法有很好的优化结果;与NSGA II相比,MOKGA有很快的收敛性。
