Digitization of documentation of white cards is currently a key aspect of preservation of national heritage. Destructive processes of archival documentation, escalation of acts of vandalism, consequences of war operations that have left their stamp on architectural objects as well as monuments of nature contributed to adaptation and introduction of the fifth form of national heritage, which is “digitization”. Digitization shall ensure the re-creation of not only lost national treasures in the future, but also shall enable researchers in architecture, archeologists, historians, conservators a research and an analysis of chosen objects and records related to it in a non-invasive and interactive way. Objects subject to digitization will be able to be analyzed more thoroughly since digital data rendered available by electronic means shall enable and facilitate an interdisciplinary research process. In the article, the author presents results that compare two methods for digitization of the chosen architectural object. Documentation consists in recording and preserving of the fragment of façade and the chosen architectural detail of the considered object. The object subject to analysis is the "Tenement under the singing frog" built in 1889-90 acc. to the project by Teodor Marian Talowski, in Kraków at Retoryki 1 St. For an analyzed example, research has consisted in application of photogrammetry and laser scanning methods to acquire information on spatial geometry of researched object and compare discrepancies of newly generated 3D models. The object presented has undergone a comparative analysis, based on which the key aspects have been isolated and then demonstrated in a graphic way, as well as specific issues related to them, such as precision and effect of distortion have been discussed. The objective of the work has been presentation of possibilities of practical application of photogrammetry as a cheaper method of digitization of architectural objects in relation to scanning method, applicable in digitization and preservation of national heritage consisting in development of new interactive documentation (white card).
Along with the increase in computing capabilities of computers and the spread of cloud computing technologies, the importance of simulation methods, in particular the Monte Carlo method, grows. The quality of the obtained results largely depends on the number sequences used in this method. The article presents the issue of creating and applying pseudorandom and quasi-random sequences. The aim of this publication was to experimentally investigate the differences in the obtained results using different number sequences for problems with a large number of degrees of freedom.

Wraz ze wzrostem możliwości obliczeniowych komputerów i upowszechnieniu technologii obliczeń chmurowych rośnie znaczenie metod symulacyjnych, w szczególności metody Monte Carlo. Jakość uzyskanych wyników w dużej mierze zależy od zastosowanych w tej metodzie ciągów liczbowych. W artykule przybliżono zagadnienie tworzenia oraz zastosowania ciągów pseudolosowych i quasilosowych. Celem niniejszej publikacji było eksperymentalne zbadanie różnic w uzyskanych wynikach przy zastosowaniu różnych ciągów liczbowych dla zagadnień o dużej liczbie stopni swobody.
