Abstract: 随着云计算的蓬勃发展,计算机行业的能耗问题日益突出。状态管理一直是优化能耗的有效方法之一。对数据中心的服务器进行合理的状态管理能带来可观的节能收益。针对数据中心等机群环境下服务器的状态能耗进行研究,提出基于状态管理的服务器能耗优化方法,以在保证性能的同时,降低了能耗。首先分析状态管理对服务器能耗带来的影响,根据分析提出服务器的状态优化策略,然后利用Petri网及其状态分析技术对该策略的状态能耗模型和性能模型进行分析。实例分析和模拟实验验证了该方法的有效性和优越性。

Abstract: Having used domain ontology in DOKB (Domain Ontology Knowledge Base) to construct new domain model or domain ontology. Knowledge Engineer need to confirm that the new domain ontology fulfills the rule bases. Computer can do this automatically by using constraints, which will reduce the workload of the KE and hasten the reusing process of knowledge.

中国物理 B , 2006,
Abstract: We have established a caesium double magneto-optical trap (MOT) system for cavity-QED experiment, and demonstrated the continuous transfer of cold caesium atoms from the vapour-cell MOT with a pressure of ~ 1×10-6 Pa to the ultra-high-vacuum (UHV) MOT with a pressure of ~ 8×10-8 Pa via a focused continuous-wave transfer laser beam. The effect of frequency detuning as well as the intensity of the transfer beam is systematically investigated, which makes the transverse cooling adequate before the atoms leak out of the vapour-cell MOT to reduce divergence of the cold atomic beam. The typical cold atomic flux got from vapour-cell MOT is ~2×107 atoms/s. About 5×106 caesium atoms are recaptured in the UHV MOT.

Abstract: This paper proposed a rule and semantic based model composition framework. It described models and the composition process formally, and put the composition rules and semantic matching algorithms. The matching elements could be automatically identified and their composition rules were determined. The composed model could be thus generated according to the rules. The framework better deals with the diversity of models and the flexibility of model names.

Abstract: Today a lot of people not only from industrial community but also from academic community simply take As- pect-Oriented Programming (AOP) as modularizing crosscutting concerns and in a narrow-mined way to believe that AOP is just an extension or an effective supplement to Object Oriented Programming (OOP). Based on the definition of AOP, its nature which makes it different from the other programming languages was dug out. And the quantified state- ment and aspect in the definition were formalized. Moreover the semantics of them were defined. And then we argued quantification and obliviousness in the definition are the real nature of AOP. Modularizing crosscutting concerns is just a benefit from it. And AOP is a new programming paradigm which is independent of all the other programming langua- ges. Based on the definition,the minimum condition set which Aspect Oriented Programming Languages (AOPI)need to satisfy was proposed. And the difference between the mainstream AOPL from the view of the definition was probed into.
The Research of Railway Line State Detection Signal Processing Method Based on EMD  [PDF]
Wen-Fa Zhu, Hui-Zhen Ma, Xiao-Dong Chai, Shu-Bin Zhen
Open Journal of Safety Science and Technology (OJSST) , 2015, DOI: 10.4236/ojsst.2015.52008
Abstract: In this paper, an EMD de-noising algorithm is proposed based on the statistical feature of random noise, which can eliminate the noise impaction digital integrator generated by the collected railway line state detection signals using strap-down inertial technology. Firstly, the first IMF component of the noise-dominant modes treated by the process “random sort-sum-average-reconstruc-tion”, the signal-to-noise ratio is improved while the noise power is weakened in this process. Then the signal-to-noise cut-off can be determined according to the characters of noise autocorrelation function. Finally, the global threshold could be selected by the noise-dominant mode component, so as to realize the function of filtering. The simulation and validation based on the collected railway line acceleration data using the EMD de-noising algorithm show that the noise in railway line state acceleration detection signals can be effectively eliminated using this method.
Investigation of Hollow Silica Spheres with Controllable Size and Shell Thickness
LI Zhen, WANG Shu-Bin
无机材料学报 , 2011, DOI: 10.3724/sp.j.1077.2011.11159
Abstract: Hollow silica spheres were synthesized by template/Sol―Gel approach, using cationic polystyrene (PS) as template and tetraethoxysilane (TEOS) as precursor. The void size of hollow silica sphere was decided by the diameter of their PS templates. Hollow silica spheres with controllable size between 0.71 μm and 1.8 μm were obtained by varying the parameters of polymerization (the monomer, the initiator, the stabilizer and the polarity of the dispersion medium). The shell thickness of hollow silica spheres could be easily changed in the range of 20 nm to 60 nm by changing the TEOS concentration from 0.4 mmol/L to 0.8 mmol/L. Both the size and shell thickness of hollow silica spheres have effects on their bulk density, the thermal conductivity and strength of materials.
Absorption spectroscopy of cold caesium atoms confined in a magneto-optical trap

中国物理 B , 2004,
Abstract: Absorption spectra of cold caesium atoms confined in a magneto-optical trap are measured around D_2 line at 852nm with a weak probe beam. Absorption reduction dip due to electromagnetically induced transparency (EIT) effect induced by the cooling/trapping field in a V-type three-level system and a gain peak near the cycling transition are clearly observed. Several mechanisms mixed with EIT effect in a normal V-type three-level system are briefly discussed. A simple theoretical analysis based on a dressed-state model is presented for interpretation of the absorption spectra.

Abstract: 反气相色谱法对聚烯烃的结晶度的测定是一种有效的方法。Guillet等用溶剂溶解聚丙烯涂覆担体,或在低温将样品磨成粉末和担体混合,填充色谱柱,以探针分子的保留时间测定样品的结晶度。我们用直径较小的色谱柱使温度迅速平衡,实验得到了Guillet关系式的外推项。将纤维剪成粉状测定,重复性尚好,不同的探针分子、柱长和聚合物含量对测定的影响不大,结果与密度法或X光法相近。
