W poszukiwaniu wykładowcy doskonałego
(2011)In nearly every student’s imagination such a character. But for students of pedagogical types of studies, this imaginary character should be of utmost importance, as it represents what they will strive to achieve when ... -
Waga zbioru tras prowadzących do węzła brzegowego na grafie stochastycznym złożonym
(2008)In this paper we present a method of calculating the weight factor of all traces leading to a fixed boundary node in a stochastic graph. The results obtained here find application in calculating probabilities of some ... -
Wall temperatures dependency determination using correlation analysis
(2015)This paper is focused on the statistical processing of temperature data measured in intelligent building with a goal to obtain their dependencies between each temperature sensor located inside the building and also inside ... -
Wartość oczekiwana zmiennej losowej i jej fizyczna interpretacja
(2008)A physical interpretation of the notion of the expected value of a random variable is considered. Relationships between the center of mass of a solid and the expected value of a random variable are showed. -
Weryfikacja metody aproksymacji połączonych (CA) w zagadnieniu własnym prostego trójwymiarowego modelu konstrukcji
(2014)In the paper combined approximations (CA) hybrid method is proposed as an effective reanalysis approach for computation of natural frequencies of the modified simple threedimensional structure. CA procedure is applied ... -
