Thermodynamic properties of n-hexane

Specific volumes and isobaric heat capacity measurements are reported for n-hexane. The measurements were made in the liquid and vapor phases at temperatures from the triple point and also cover a wide region around the critical point. The thermal, caloric, and acoustic data from our own investigation as well as those of a number of other authors are fitted to a single equation of state with 32 constants. This equation yields to all thermodynamic properties of n-hexane in the temperature range 180 to 630 K and pressures up to 100 MPa. The data in the critical region have been analyzed in terms of a scaled equation of state.     

Model-based segmentation of grey-tone images

A model-based approach to grey-tone image segmentation is presented. A conceptual and computational frame is described, in which a variety of image models can be accommodated. Each model is defined by a feature pair and implies a uniformity criterion for ideal regions. Some particularly relevant models are described in detail and illustrated by means of experimental results obtained with real-world images.     

Analysis of causes of erosion-corrosion wear of the metal of internal surfaces of watered regions of tubes of heat-exchange devices

Causes of the appearance of erosion-corrosion wear (ECW) on inlet regions of tubes of heat-exchange devices are considered. Experimental data are used for determining the mechanism of the ECW process and suggesting measures for its prevention. __________ Translated from élektricheskie Stantsii, No. 11, November 2005, pp. 56–62.

结构控制系统的模态能控度及其计算方法

根据结构控制系统的特点,提出了结构控制系统模态能控度的概念,进而提出了对各解耦子空间状态向量的规范化处理,并给出了规范化因子的计算公式。在此基础上,得到模态恢复区域任一方向上边界点向量的解析表达式。由此求出的模态恢复区域、模态能控度,是其真值的最佳逼近值。因此,本文发展和改进了Viswanathan C N 等提出的能控度概念及其计算方法,为应用能控度准则判断结构控制系统作动器配置方案的优劣,提供了一个可靠的工具。本文给出一个颤振主动抑制系统不同控制面配置方案模态能控度计算、比较的算例。

油气聚集保存的时间性和有效性分析——油气有效成藏期及有效成藏组合研究

在探索盆地油气成藏规律的研究中,要系统地研究储层流体系列(天然气、原油、沥青及水中有机质)含有油气生成、运移聚集、演化与氧化、破坏与保存等诸多方面信息的有机地球化学特征和赋存特征.当将它们与形成上述特征的地质背景(包括构造史、埋藏史、沉积成岩史、孔隙发育史、油气史)动态地结合起来进行研究时,发现油气的聚集和保存具有明显的时间性和有效性,并进而可以获得盆地油气有效成藏期及有效成藏组合的有用信息,从而为现实的油气勘探服务.     

The implementation of synchronizing operations in various environments

Since E. W. Dijkstra's work on the mutual interdependencies of co-operating sequential processes there has been much discussion on various synchronizing mechanisms. This discussion usually leads to abstract definitions of synchronizing primitives. However, their realization proceeds differently in various environments. Length of critical regions, number of processors, and dispatching strategy have to be taken into account. In this paper is presented a family of synchronizing operations, the members of which are all based on the same fundamentals. They have been designed with the concept of structured programming in mind.     

Symmetry analysis by computer

Approximate locations of axes of symmetry of a 2-dimensional region are detected on the basis of its border. The border, described in terms of certain directional codes, is treated as a regular polygon in a hierarchical manner where a lower level means a greater number of sides. At each level of the hierarchy, the best axis of symmetry is found which for a lower level gives a more accurate position of the unknown axis of symmetry than for a higher level. Along with an axis of symmetry, a certain error is found on the basis of which the degree of symmetry of a 2-dimensional region is defined. Programs are written in FORTRAN IV and are implemented on an EC-1033 computer.
