The logistic services belong to the network services and it is possible to look similarity with other services such as transport and telecommunications. On this basis, the paper shows that by use of sufficient disaggregation, the logistic system can be analysed by network layers. This new theoretical approach will be represented by designed logistic system model based on three layers: logistic infrastructure, technology of transportation and passive infrastructure of logistic network.

W artykule opisano projekt oprogramowania diagnostyczno-sterującego licznika czasu z kodowaniem wielokrotnym w niezależnych liniach kodujących, wykonanego w układzie programowalnym Spartan-6 firmy Xilinx. Przedstawiono sposób sterowania licznikiem czasu, koncepcję oprogramowania sterującego, jego zadania oraz warstwową budowę. Opisano graficzny interfejs użytkownika programu i jego funkcjonalność. Prezentowane są także wyniki badań eksperymentalnych licznika czasu.

This paper presents the diagnostic and control software of a time interval counter with multi-edge coding in independent coding lines, implemented in the Spartan-6 FPGA device manufactured by Xilinx. The method of time-to-digital conversion [1] is presented along with the design of the time interval counter (Fig. 1). Subsequently, the main goals of the control software, along with its logical structure, are described. The paper shows the layer model (Fig. 2) of the program, reveals the method of communication with the time counter and the way of decoding measurement frames. The bottom-most communication layer transfers the data through USB to the device. The next control layer operates on hardware registers and the measurement layer calibrates the counter and triggers measurements. Finally, the graphic user interface (GUI) layer binds the application together and steers the user interface. The program operates in two main modes: calibration and time interval measurement. Apart from both these modes, the data flow across the layers and the way of saving data generated during counter operation are described. The GUI (Fig. 3) is described as well, showing the main types of operation along with the capabilities of configuring the calibration and measurement processes. Finally, the paper presents the test results of the time counter in both main operation modes (Fig. 4).

The paper characterizes the method of layer model building, basing on the computer tomography images, which can be used in the reverse engineering and rapid prototyping systems. The method of layer model building does not use STL (stereolithography) format as the interface between CAD (Computer Aided Design) software and the rapid prototyping machines. It gives opportunity for cost reduction of CAD software, because the software does not require the complicated algorithms for mesh triangular facets) creation basing on the model sections, which were acquired by computer tomography apparatus.

W artykule przedstawiono opracowany algorytm budowy modelu warstwowego, wykorzystujący obrazy uzyskane metodami tomografii komputerowej. Algorytm jest stosowany w systemach inżynierii odwrotnej i szybkiego prototypowania. Algorytm nie używa formatu STL do wymiany informacji pomiędzy systemem CAD i urządzeniem do szybkiego prototypowania. Stwarza więc możliwość zmniejszenia kosztów oprogramowania CAD. Nie wymaga stosowania skomplikowanych algorytmów tworzenia powierzchni fasetkowych na punktach przekrojów modelu, uzyskanych podczas analizy obrazów tomograficznych.

This article presents a new algorithm for hidden-segment elimination on the plane. A condition of equivalence of two solutions of hidden-segment elimination problem is presented. On the basis of the results a new approach to efficient solution of hidden-surface elimination problem for investigated 3D medical images is suggested.
