    • The invention concerns a new method for automatically and dynamically generating hierarchical topological trees of 2D- or 3D-structural formulas for structurally characterized chemical compounds, especially drug-like molecules, wherein the molecular graph of each 2D- or 3D-structure for a chemical compound is analyzed in terms of topological key features, the Largest Topological Substructure (LTS) and the proper Topological Cluster Centre (TCC) are created for each molecular graph, the ranking of the classes of topological key features and/or the ranking within each class of topological key features present in the TCC is used to generate a connected hierarchical Topological Sequence Path (TSP) of sentinel molecules from each molecular graph, and different molecular graphs and their Topological Sequence Paths (TSPs) share common vertices for common topological key features thus growing a Topological Structure Tree (TST), each chemical compound from the input stream is attached as a leaf node to the appropriate Largest Topological Substructure (LTS) node in the tree.

    • The length and attenuation of a signal line between a transmitter and a customer premises equipment is to be estimated. A frequency dependent line input impedance (Zin(f)) as seen from the transmitter, is measured and an absolute impedance value (œ Zin(f) œ) is generated. The latter is shown as a curve (A1) in the diagram with the frequency (f) on the abscissa and the impedance (œ Zin(f) œ) on the ordinate. Extreme values (Max.1, Max2, Max3; Min1, Min2, Min3) arc denoted and a frequency distance (FD1-FD4) between two consecutive of the extreme values is generated. The line length (L) is generated as L=½·vop/FD1, in which vop is the velocity of propagation of a signal on the line. The attenuation is estimated by multiplying the line length with an average attenuation value for the actual line type. The advantages are that the line length can be estimated with good accuracy in a simple manner for short lines and that the line attenuation is estimated in a simple manner.
    • 要估计发射机和客户端设备之间的信号线的长度和衰减。 测量从发射机看到的频率相关线路输入阻抗(Z <>(f)),并且在(f)oe中的绝对阻抗值(oe Z < 被生成。 后者在图中以横坐标中的频率(f)和纵坐标上的阻抗(oe Z(o))表示为曲线(A1)。 表示极值(最大值1,最大值2,最大值3,最小值1,最小值2,最小值3),并产生两个连续极值之间的频率距离(FD 1 -FD 4)。 线长度(L)被生成为L =½.vop/ FD 1,其中vop是线上信号的传播速度。 通过将线路长度与实际线路类型的平均衰减值相乘来估计衰减。 优点是可以以简单的方式对线路长度以良好的精度估计线路长度,并且以简单的方式估计线路衰减。
