Własności prawdopodobieństwa błędnie sugerowane przez prawdopodobieństwo klasyczne
(2002)The test discussed in this paper is a specific set of problems used to asses certain competences in the domain of the probability theory and in the domain of logic. The content of each problem placed in this test verifies ... -
Nietendencyjność losowania metodą „marynarza* jako problem stochastyczny
(2002)The main objective of this paper is the answer to the question: „Is using the „sailor” method fair, when choosing a random person?” In this method, at the appointed sign, each participant n sticks out 1 to 5 fingers of ... -
Osobliwe własności modeli probabilistycznych czekania na serie sukcesów i porażek
(2002)This paper concerns, specific, not well known but simultaneously elementary means of argumentation used in the process of constructing probabilistic spaces and calculating the probability in those spaces. The above ... -
Hazardowa wersja gry Penney'a
(2002)At first, Penney’s game and hazard Penney’s game was defined (some kind of games played with a coin). This article, in great part, is about hazard Penney’s game. It shows how Engel’s graphs can be used to calculate ... -
Selected aims of teaching mathematics and the problem-solving process
(2003)The contribution will present a study, which was meant as an attempt to diagnose the realization of those aims of teaching mathematics that assume modeling active attitudes and behaviors of students during the process of ... -
Perception of rectangular and skew structures in a row-column arrangement of figures
(2003)The aim of the reported research is identification of difficulties and natural developmental limitations in understanding of a Row-Column Arrangement of Figures (RCAF) by 10-13 years old children. RCAF includes the ... -
Street gambling, mathematization and the mathematical expectation
(2003)Concepts, theorems and the methodology of probability calculus were born - no doubt for that - in gambling saloons. In the gambling land we find traces of history and culture, but also of sciences. The present paper ... -
On the understanding of geometric transformations by mathematics freshmen
(2003)Two questions will be discussed in my paper. The first one concerns difficulties the first year university students meet while learning definition of the geometrical transformation. The second question - the incorrect ... -
Solutions to a certain problem illustrating the idea of fusionism in the probability theory
(2003)The solutions presented above may serve as an illustration of "the principle of internal integration”, known as the idea of liisionisiii. Three balls are selected simultaneously from an urn containing b white balls and ... -
Awaiting the series of colors - stochastic graph as a means of mathematical treatment and argumentation
(2003)This paper presents methods of calculating the probability of events related to Markov’s homogeneous chains theory. The main means of argumentation being the stochastic graph. -
On new differential equations of the first order in the space $M(1,4) x R(u)$ with non-trivial symmetries
(2003)Some new differential equations of the first order in the space $M(1,4) x R(u)$, which are invariant under splitting subgroups of the generalized Poincaré group $P(1,4)$ are presented. -
A proof of S. Rolewicz's conjecture
(2002)S. Rolewicz’s conjecture concerning solutions of the functional-differential inequality (P) is proved. -
Sur quelques problèmes ouverts
(2001)On pose les problèmes au sujet de la raréfaction des ensembles, des prolongements de la mesure de Jordan et des homomorphismes, de la stabilité de l’équation de translation, de la décomposition des fonctions et sur les ... -
Sur les généralisations du wronskien
(2001)En généralisant le wronskien on montre que l’évanouissement de ce wronskien est équivalent à la dépendance linéaire du système des fonc tions. Le théorème analogue est donné pour la décomposition d’une fonc tion $h(x, y)$ ... -
General continuous solution of a nonlinear functional inequality
(2001)In this paper we present theorems on the existence of continuous solutions of the functional inequality (1) in the case where the continuous solution of the corresponding functional equation (2) is not unique. -
Ternary semigroups of linear mappings and matrices
(2001)Following the classical Green’s equivalences we examine, by means of some equivalence relations, the structure of the ternary semigroup of linear mappings. The suitable results for the ternary semigroup of matrices are ... -
Wpływ niestechiometrii na zmiany czasowe i temperaturowe prądu depolaryzacji ceramiki niobianu sodu
(1986)Time and temperature changes of polarisation and depolarisation currents of the $NaNbO_3$ ceramics samples assumed to have correct stoichiometric content and of the samples $NaNbO_3$ having the excess of niobium or sodium ... -
Zjawiska fotoelektryczne w monokryształach BaTiO[3] w obszarze niskotemperaturowych przejść fazowych
(1986)This work concerns ferroelectric phenomena in monocrystals BaTiO[3]. Influence of light illumination on electric conductivity and on phase transition temperature was studied in particular. It was found that illumination ... -
Wpływ stałego pola elektrycznego i magnetycznego na zmiany temperaturowe przenikalności elektrycznej w BaTiO[3]
(1986)Influence of the constant electric field on temperature changes of electric permeability in BaTiO[3] were studied. It was found that the Curie temperature shifts towards higher value and that the value of max decreases ...
