The paper presents the analysis of the orientation of 60 mosques built in the XV and XVI centuries in the Balkans’ region of former Yugoslavia. The mosques have been selected according to their ...architectural value - mostly the dome mosques that were built by the most renowned builders. Based on the geographic coordinates, the qiblas of all mosques were calculated and the azimuths of their axes measured on orthophotographs. Statistical analysis has shown that the axes of these mosques vary in the horizon sector that is five times wider than the calculated sector of the correct qibla, with a systematic deviation of –10° 15' in relation to the correct qibla. Connections between deviations of the architectural design (dome mosques and other mosques), location and elevation have not been identified. However, a connection between deviations and the time of construction has been identified: deviations from the qibla are smaller in mosques built at a later date. The paper has laid the groundwork for future analysis of the causes of the aforementioned deviations: in the XV and XVI centuries there were no accurate geographic coordinates of locations and the builders were not able to calculate (take over, measure) the exact qibla direction, regardless of the method they applied.
Diffusion of information and communication technologies is a global phenomenon. In spite of rapid globalization there are considerable differences between nations in terms of the adoption and usage ...of new technologies. Several studies exploring causal factors including national cul tures of information and communication technology adoption have been carried out. The focus of this paper is slightly different from other studies in this area. Rather than concentrating on the individual information technology an overall eGovernment readiness is the focus. This research conducted an analysis of the impact national culture has on eGovernment readiness and its components for 95 countries. eGovernment readiness assessment used in this study is based on the UN Global eGovernment Survey 2003, while the national cultural dimensions were identified using Hofstede's model of cultural differences. The research model and hypotheses were formed and tested using correlation and regression analysis. The findings indicate that worldwide eGovernment readiness and its components are related to culture. The result has theoretical and practical implications.
Human–computer interface was utilized to amplify the power of a hybrid algorithm that combines fuzzy logic, regression analysis, and non-linear optimization to extract knowledge from a roll pass ...design database. This strategy is applied to grooves with vertical and horizontal symmetry which are employed in initial passes to roll a broad range of steel products. The results presented here from the case study are both statistically significant and valid from the viewpoint of roll pass design theory.
Nelinearni metodi ocenjivanja proizvodnih funkcija direktno ocenjuju sve parametre jednovremeno, za razliku od pristupa baziranih na linearnim aproksimacijama, gdje se fiksiraju vrednosti pojedinih ...parametara ili parcijalnog ocenjivanja koeficijenata.
U radu je izložen opšti pristup nelinearnim metodama ocenjivanja, pretpostavke na kojima se zasnivaju, osobine dobijenih ocena kao i statistička procedura vrednovanja dobijenih ocena.
