The paper analyzes the problem of interpretations Gettier problem. author draws a distinction between counterexamples presented in Edmund Gettier’s article and Gettier-style cases, general epistemological supposedly occurring all or many cases. It is argued that there gap associated with an insufficiently defined concept justification, which does not allow talking about without any explicit imp...

Some application driven fast algorithms developed by the author and his collaborators for elliptic partial differential equations are briefly reviewed here. Subsequent use of the ideas behind development of these algorithms for further development of other algorithms some of which are currently in progress is briefly mentioned. Serial and parallel implementation of these algorithms and their ap...

The paper deals with training the neural models of microwave structures. The first, an artificial neural network (ANN) is trained with basic genetic algorithm (GA). Training abilities are discussed. Further, the modification of GA and an approach to learning artificial neural networks (ANN) with backpropagation is described. Neural networks are implemented in MATLAB. Results of training abiliti...

The purpose of the study was to identify subjective experiences that are characteristic of schizophrenia. A questionnaire for self-assessment of disturbances in several cognitive-perceptual areas (the Eppendorf Schizophrenia Inventory) was constructed and administered to first episode schizophrenia patients (SCHf; n = 45), negative-syndrome schizophrenia patients (SCHn; n = 45), remitted schizo...

We survey research on multi-user brain-computer interfacing applications and look in particular at ‘multi-brain games’. That is, games where in one or other form the (EEG-) measured brain activity of more than one user is needed to play the game. Various ways of integrating and merging brain activity in a game context are investigated. Existing research games are mentioned, but the emphasis is ...

I will describe von Neumann’s elegant idea for sampling from the exponential distribution, Forsythe’s generalization for sampling from a probability distribution whose density has the form exp(−G(x)), where G(x) is easy to compute (e.g. a polynomial), and my refinement of these ideas to give an efficient algorithm for generating pseudo-random numbers with a normal distribution. Later developmen...

The present status of the quasi-local mass, energy-momentum and angular-momentum constructions in general relativity is reviewed. First, the general ideas, concepts, and strategies, as well as the necessary tools to construct and analyze the quasi-local quantities, are recalled. Then, the various specific constructions and their properties (both successes and deficiencies are discussed. Finally...
