Warsaw, December 15, 2012 Dear Ladies and Gentlemen, Regrettably, I have to inform you that due to the mission assigned to me by the European Parliament regarding the trial of Julia Tymoszenko in Ukraine, I had to depart on an unplanned trip abroad. Contrary to my earlier plans, today I cannot take part in the discussion on cooperation between China and Europe. During the ten years of my presidency, I took actions aiming at deepening the

The UPS （uninterruptible power supplies） are essential power infrastructure components of systems designed for critical application, including data centers. High availability achievement is a very important factor related to UPS performance, consequently to proper critical application functionality. Generally, UPS have a limited input voltage window, referring to the nominal input voltage value. Goal of this paper is to prove larger voltage window, without affecting normal UPS operation. Larger window will result on less commutation, backup and normal mode reduction, and consequently duty time of batteries reduction, too. Thus, under these conditions, it is to be expected availability improvement. The stabilizing node model, applied at UPS＇s control part through this paper is presented. UPS＇s behavior with an implemented stabilizing node is observed at few sites. In order to analyze and conclude about UPS＇s performance under these technical conditions, simulation results are further presented.

＜正＞ Diffusion layers produced on carbon steel surface in vacuum titanizing process were investigated. Studies of layers thickness, their morphology, titanium, carbon and iron concentration depth profiles in the diffusion zone of titanized layers were carried out. The effect of process parameters such as time and temperature on the kinetics of layer growth on steel surface was investigated. Tribocorrosion resistance of titanized layers was determined.

本研究试图找出中国和非洲之间贸易背后中最重要的驱动因素,试图找出中非贸易中最重要的是否是政治或市场力量。历史模式被描述成长期角度看待贸易。然后在中国治国理论来用来观察中非贸易是否适合在中国有意识的政治策略。在研究的第二部分,使用一种基于贸易引力模型的计量经济学回归分析法来计算,这是中非贸易背后的最重要的驱动。该变量被分成两组的政治和市场驱动力。最终发现市场驱动是最主要的驱动程序,但有着显著的政治影响力。

为了解决单域环境下访问控制模型无法满足跨企业服务组合的访问授权需求的问题,提出一种以基于角色访问控制(RBAC)为基础的多域动态访问授权模型.根据组合服务的流程结构分析服务执行所需的权限,提出一个权限最小化的角色集挖掘算法,从原有的面向单域的角色授权关系中搜索满足服务执行的角色集.针对组合服务中的跨域操作进行端对端的域间自主授权协商,并根据挖据出的角色集建立最小成本的跨域角色映射以满足跨域访问授权需求.在此基础上提出一套与现有的工业标准相结合运行时框架,实现根据组合服务实际运行状态进行授权的动态访问控制机制.模拟实验结果验证模型中的该算法的主要部分在多种不同场景下的有效性.

Nano-mechanisms of crystal lattice deformation on the interface of dissimilar materials (Cu-Nb), joined by vacuum rolling in solid phase under high temperature (950℃) were studied by means of high resolution electron microscopy. Input of carriers of rotation modes—nano-dipoles of partial disclinations and nano-twist disclinations in the form of double spirals in deformation mechanisms were analyzed. The role of these mechanisms in decrease of shear stability of the interface areas and in production of high-quality rolled metal is discussed.

It is generally thought that a single ejaculate is a bad predictor of semen quality of a subject, because of significant intra-individual variation. Therefore, we investigated the degree to which the results of a first semen analysis differ from that of a second analysis among men from a how the two different semen results mirrored the overall general population in Norway. In addition, we analysed semen quality assessment. A total of 199 volunteers participated in the study and delivered two semen samples with an interval of 6 months. The semen parameters were determined according to the World Health Organization （WHO） 1999 guidelines, which were also used to determine whether semen quality was normal or abnormal. In addition, the DNA fragmentation index （DFI） was determined using the Sperm Chromatin Structure Assay. The two samples from each individual were very similar with regard to standard semen parameters and DFI （rs： 0.67-0.72）, and there were no significant systematic differences between the two samples. The result of the first sample （normal/abnormal） was highly predictive of the overall conclusion based on the two samples （sperm concentration： in 93% of the cases （95% confidence interval [CI]： 89%-96%）; sperm motility： in 85% of the cases （95% CI： 79%-89%）; overall semen quality： in 85% of the cases （95% CI： 80%-90%）. In epidemiological studies, one ejaculate is a sufficient indicator of semen quality in a group of subjects. In a clinical situation, when the question is whether the semen quality is normal or not, the first ejaculate will, in at least 85% of cases, give a correct overall conclusion.

The paper presents the study of hierarchy of deformation wave-processes from nano- to macro-structural level, which takes place in dissimilar materials, bonded by high-temperature vacuum rolling in solid phase. The focus was on the processes that occur on the interface of the bonded materials: mass trasfer of impurities and alloying elements stimulated by deformation, the study of nano- and micro-hardness.

We developed a detailed simulation model of the Arctic marine transport system(MTS) for oil platform Prirazlomnaya. The model has a multidisciplinary nature and involves: sub-models of various transport and technological processes; stochastic weather generator to obtain time series of 15 environmental parameters; and contextual planning algorithm to build voyage plan considering several types of ships and cargoes. We used a significant amount of real operational data to identify model parameters and to prove its statistical reliability. Our main scientific task is to investigate the interaction of various processes of a different nature, while the practical aim is to find a set of measures to increase the efficiency of MTS. The results of the study reveal many examples of the mutual interaction of various processes that need to be considered at the design stage to avoid technical *** study formed a basis for making managerial decisions at the top level of Gazprom Neft Shelf Company.
