通常我们在执行程序时。需要先进入该程序所在的目录。然后运行它。显得非常麻烦。为了方便。在桌面上建立一个快捷方式。但带来的结果却是满屏的程序快捷方式。前几天。看见朋友在“运行”对话框中输入Foxmail.exe后即可运行Foxmail。感到挺奇怪的。在我机器上一试。却提示找不到该文件。这是为什么。该问题该如何解决。下面提供两种解决办法。至于为什么。在第二种方法中已说明。 相似文献

许多人在接触家用电器的金属外壳时。曾遇到过有“麻电”的感觉。严重时甚至有刺痛的感觉。“麻电”是一种危险的征兆。轻则引起使用者精神紧张。重则危及使用者的生命安全.发生触电伤亡事故。因此。当发生“麻电”现象时。必须暂停使用。找出“麻电”的原因。及时排除电器的故障。同时也应采取必要的技术措施避免“麻电”现象的再次产生。 相似文献

她是个人电脑的始祖。是那么的卓尔不群。气质不凡。如今似乎被排挤在我们视线的边缘。却仍是我们事实上的潮流引领者。每一款新产品的问世。都可以引起无数人的欢呼。再昂贵的价格也无法阻挡人们对这些艺术品的热爱。但是这是个商业化的社会.尊崇着利益至上的原则。因此她作为一个艺术家.一直遭受着各种各样的磨难。无数未来佳作被迫胎死腹中或是半路夭折。但是他并没有因此倒下。反而变得越来越成熟。今天的她不但更善于创造.同时也更善于生存。世界尚未终结。她的成败功过也无法断定。我们只好藉着过去的回忆。让大家自己来思考…… 相似文献

我会听很多很多的歌,以至于有点乱七八糟。要知道,我的CD多得无法摆上书架。音乐是我的一切。有时侯我会觉得自己是为音乐而生的。音乐就是我的耳朵。这感觉来得如此真实,如此强烈,以至我有些自恋。我就像是一个歌者,台下是已成黑点的观众。而我,从不曾倒下,经常会这样子近乎发呆地想。 相似文献

提到上网收费。大家理所当然地想到当前最为普遍的包月方式。通常我们每个月只要付出60—100元左右的费用,我们就可以无限制地使用网络;也有的用户使用网络比较少。因而使用的是按时间计费的方式。通常可以50元包50个小时。70元包100个小时等。然而。你可曾听说宽带将按流量进行计费。这意味着你在网络上一切导致流量的行为都要收费。包括浏览时事新闻、查阅资料、下载歌曲、软件、电影等。你所浏览的每一个字符,每一bit流量。都需要你买单。 相似文献

This paper presents the latest results in the application of developed multiscale correlative signal dynamics analysis to
epileptic discharge investigations. The basic principle of the approach proposed is in detecting the epileptic discharge time
intervals and controlling the signal dynamics in such intervals by means of some signal quasi-periodicity features. These
features are determined by the structure of a measure of self-similarity calculated for different scales. The graphical temporal
representation based on this measure is at the center of the discussion. Interpretations of typical epileptic discharge dynamics
patterns in the representation proposed are put into practice; typical patterns are illustrated by experimental representation
examples.

A flexible approach to automation of parallel programming of the problems of mechanics of the multiphase media was proposed. It is based on the object-event model of program generation. The model structure was described. The principles of interpretation and the technology of model translation into the program code were formulated. For solution of the aforementioned mechanical problems with spatial parallelization, strategies of reduction and optimization of data exchange were proposed. Part of exchanges was eliminated owing to periodic extrapolation. The least squares method with adjustable weight coefficients in the objective function was used. For optimization of the rest of exchanges, a special problem of nonlinear Boolean optimization was solved. 相似文献

The paper is devoted to the use of spectral methods in problems of visual pattern recognition. The main idea is to associate
a two-dimensional closed line, treated as a univariate function, with the contour of each object. On the basis of analysis
of expansion coefficients of these functions, we propose adequate quantitative estimates for similarity of objects, which
are invariant under affine transformations of the plane. A particular result is the invariance of the spectral representation
with respect to the choice of the start-point. This invariance is obtained on the basis of the sine-cosine decomposition of
arbitrary periodic functions.

Mathematical model of motion of a paraglider in the longitudinal plane is constructed. The vehicle consists of a sail and a gondola. Both bodies are assumed to be perfectly rigid. They are connected by slings which are assumed to be perfectly rigid rods. Thus, the considered model of the paraglider represents one rigid body with three degrees of freedom. An engine, which develops thrust using a propeller, is mounted rigidly on the gondola of the vehicle. The orientation of the thrust vector with respect to the gondola is constant. The steady-state regimes of motion of the paraglider for the constant thrust are found. The law of automatic thrust control for which the flight of the vehicle is stabilized at the given altitude is designed. The domains of asymptotic stability of the paraglider motion at a constant altitude, including with account of delay, are constructed in the plane of the feedback coefficients. In this plane the domains in which a given stability factor is ensured are constructed. Some results of numerical simulation of the flight of the vehicle are presented. 相似文献

An easy measure of compactness for 2D (two dimensional) and 3D (three dimensional) shapes composed of pixels and voxels, respectively, is presented. The work proposed here is based on the two previous works of the measure of discrete compactness [E. Bribiesca, Measuring 2-D shape compactness using the contact perimeter, Comput. Math. Appl. 33 (1997) 1–9; E. Bribiesca, A measure of compactness for 3D shapes, Comput. Math. Appl. 40 (2000) 1275–1284]. The measure of compactness proposed here improves and simplifies the previous measure of discrete compactness. Now, using this proposed measure of compactness, it is possible to compute measures for any kind of object including porous and fragmented objects. Also, the computation of the measures is very simple by means of the use of only one equation. The measure of compactness proposed here depends in large part on the sum of the contact perimeters of the side-connected pixels for 2D shapes or on the sum of the contact surface areas of the face-connected voxels for 3D shapes. Relations between the perimeter and the contact perimeter for 2D shapes and between the area of the surface enclosing the volume and the contact surface area, are presented.The measure presented here of compactness is invariant under translation, rotation, and scaling. In this work, the term of compactness does not refer to point-set topology, but is related to intrinsic properties of objects. Finally, in order to prove our measure of compactness, we calculate the measures of discrete compactness of different objects. Also, we present an important application for brain structures quantification by means of the use of the new proposed measure of discrete compactness. 相似文献
