An embedded time interval data acquisition system (DAS) is developed for zero power reactor (ZPR) noise experiments. The system is capable of measuring the correlation or probability distribution of a random process. The design is totally implemented on a single Field Programmable Gate Array (FPGA). The architecture is tested on different FPGA platforms with different speed grades and hardware resources. Generic experimental values for time resolution and inter-event dead time of the system are 2.22 ns and 6.67 ns respectively. The DAS can record around 48-bit x 790 kS/s utilizing its built-in fast memory. The system can measure very long time intervals due to its 48-bit timing structure design. As the architecture can work on a typical FPGA, this is a low cost experimental tool and needs little time to be established. In addition, revisions are easily possible through its reprogramming capability. The performance of the system is checked and verified experimentally.

The subject of my contribution is the cognition in the jurisprudence. It focuses on the question of the methods used in the jurisprudence to achieve knowledge of the law and the importance of the language in this process. My considerations focus on the evaluative position of the jurist. It is based on the assumption that the choice of a view requires not only an evaluation but also a kind of hierarchization. Therefore the important question is which evaluations are displaced by jurisprudence, and which ones creep into the theoretical considerations. The arguments on this topic have been drawn from three texts by German jurists of the 19th century.
