ON THE MAXIMAL QUANTITY OF PROCESSED INFORMATION IN THE PHYSICAL ESCHATOLOGICAL CONTEXT
PROCESSED INFORMATION PHYSICAL ESCHATOLOGICAL CONTEXT MAXIMAL QUANTITY
2009/3/16
An estimate of the maximal computing power available to advanced
extraterrestrial or future (post)human civilizations is presented. It is shown that the
fundamental thermodynamical considerations ma...
A COMPARSION OF TWO SPHERICAL MASS DISTRIBUTION MODELS
MASS DISTRIBUTION MODELS Two spherically symmetric generalised isochrone model
2009/3/13
Two spherically symmetric mass-distribution models - a special
case of the generalised Schuster density law and the generalised isochrone model
(both yield the same approximate density dependence on...
The life and scientific and professional activities of Danilo Zulevi´c
(1937 − 1998), research fellow of the Belgrade Astronomical Observatory, are presented,
followed by the Bibliograph...
Using a semiclassical approach, we have calculated electron−, proton−,
and He II−impact line widths and shifts for 52 Be III multiplets as a function
of temperature and perturber d...
Using a criterion proposed by Salpeter and standard solid-state
physics, we have determined the Debye temperature of a solid in equilibrium with
the electron gas surrounding it. The results obtained...
We find that any really close concentration of positions of poles of
orbital planes for binaries is not affected by the corresponding positions of ”mirror
poles” for the same orbital planes. Namely,...
ORBITS OF 6 BINARIES

2009/3/6
In this paper the orbits of binaries WDS 10093+2020 = A 2145,
WDS 210740814 = BU 368 AB and WDS 222880001 = STF 2909 AB are re-
calculated because of significant deviations of mo...
ORBITAL ELEMENTS, DYNAMICAL MASSES AND PARALLAXES FOR 4 DOUBLE AND ONE TRIPLE SYSTEMS

2009/3/2
New orbital elements for four binaries: WDS 00416+2438 = WRH
28, WDS 01554+0257 = A 2407 = ADS 1530, WDS 15031+4439 = CHR 43 and
WDS 22550+5132 = HU 785 = ADS 16368 and one triple star WDS 23393+454...
The space debris population is similar to the asteroid belt, since
it is subject to a process of high-velocity mutual collisions that aects the long-
term evolution of its size distribution. Presen...
More than a decade elapsed after the HIPPARCOS ESA missi-
on (ESA 1997) observations have been collected. This rst astronomical satellite
mission was less than 4 years long so that 1991.25 is the e...
基于卫星遥感数据的地质断裂分形研究——以江西德兴为例
分形 遥感 断裂带 先进对地观测卫星影像
2013/9/27
利用分形理论分析了德兴地区断裂构造的特点。结果表明,不仅研究区内的断裂带有自相似性,子区域也有相似现象。矿产区的分维值略高于整个研究区,铜矿区分维值高于金矿区,NW、NWW走向断裂带的分维值远高于SE走向的。说明分维值越大,越有利于矿床的形成;分维值越大的断裂走向,对矿床的产出位置控制作用越明显;地质构造复杂程度越高,分维值也越大,线性展布也越复杂。
太阳活动的甚长周期性变化
太阳活动 太阳黑子 Lomb-Scargle谱分析 小波变换
2013/10/9
近期Solanki等利用树木年轮中14C含量变化的测算资料, 重建了过去10000多年间采样间隔为10 a的太阳黑子数序列, Usoskin等则利用地磁变化资料重建了过去近7000年间采样间隔也为10 a的太阳黑子数序列. 本文采用Lomb-Scargle谱分析方法研究了这两个序列, 得到了太阳活动的百年至千年时间尺度的周期和准周期, 它们大约为225, 352, 441, 522和561 a以及...
