The DCF77 Decoder - Fast Code Generator
Skotnica, M.
Signal of the DCF amplitude-modulated transmitter, located in Braunschweig (Germany) is widely used for synchronizing of time information during different laboratory and field experiments. The full time information of this time normal is coded and presented within every minute using different length of second time marks. The knowledge of the exact time of occurrence of seismic events is the fundamental information during the seismic activity monitoring. With respect to the fact that the duration of individual records having sometimes a few seconds at minimum, the time generator ensuring the complete time information within every second, is needed. That is why the special timing device controlled by the DCF77 signal and generating every second the full time information was developed. Description of the function of decoder, internal clock and fast code generator implemented on the basis of FPGA circuits is the subject of this paper.

Approximation of the Characteristic Functions - Using the Fuzzy Approach
Pokorny, M.
To approximate the real characteristic functions of the non-linear electronic elements various mathematical methods are used. Such methods offer the analytic approximating mathematical expressions as their results. One of the interesting non-conventional method for the approximation task is the approach of the fuzzy sets theory and fuzzy multivalue linquistic logic. To apply of this method we obtain the approximation functions of the non-linear fuzzy rule based form. To design of such fuzzy model we use the approaches of the fuzzy non-linear regression analysis. The article describes the structural and parameters identification of such model and introduces the results of the numerical experiments.

The Vector Modification of Huyghens-Fresnel Principle
Popelek, J.; Follner, R.
The present approach to the diffractive element design is based on Kirchhoff scalar theory of diffraction. Predictions made by this theory become unreliable if the diffraction of polarized light is evaluated. The paper presents the vector correction of Huygens-Fresnel principle and suggests a method for fast evaluation of rapidly oscillating integrals.

Testing Samples of Three Independent Groups
Froncek, D.
A method of testing triples consisting of samples of three independent groups such that no two samples of the same group are tested at the same time, no sample is tested with another one more than once and after each test one sample of the triple is included in the following triple is presented.
