Three vernacular texts from late-13th-century Bohemia, in Middle High German and Old Czech, integrate motifs associated with the Holy Land, pilgrimage and the crusades. The romance Wilhalm von Wenden manifests the late Přemyslids’ royal ideology by portraying an independent, pious ruler who derives authority from Jerusalem. The Alexandreis explores the psychology of a military expedition to provide ground for moral reflection and draws on cartography to exploit the symbolism of Jerusalem’s geographic centrality. The crusade-related details in the Legend of Saint James the Less attest to an informed use of intertextual practices.

Precise wind energy potential assessment is vital for wind energy generation and planning and development of new wind power plants. This work proposes and evaluates a novel two-stage method for location-specific wind energy potential assessment. It combines accurate statistical modelling of annual wind direction distribution in a given location with supervised machine learning of efficient estimators that can approximate energy efficiency coefficients from the parameters of optimized statistical wind direction models. The statistical models are optimized using differential evolution and energy efficiency is approximated by evolutionary fuzzy rules.
