In this note, we compare two approaches for handling risk-variability features arising in discrete-time Markov decision processes: models with exponential utility functions and mean variance optimality models. Computational approaches for finding optimal decision with respect to the optimality criteria mentioned above are presented and analytical results showing connections between the above op...

Conducted analyse of the knowledge of design brick arched lintels shows lack of information about the mentioned process. The only piece of information, reached by the author, includes simplified matching method of arch’s shape by empirical use of ultimate limit state method. Presented paper contains review of more interesting empirical and numeric research. Additionally, the analyse of technica...

In this paper, a two-dimensional multi-wavelet is constructed in terms of Chebyshev polynomials. The constructed multi-wavelet is an orthonormal basis for space. By discretizing two-dimensional Fredholm integral equation reduce to a algebraic system. The obtained system is solved by the Galerkin method in the subspace of by using two-dimensional multi-wavelet bases. Because the bases of subs...

Background: Acne vulgaris is a self-limited disease that mainly involves the sebaceous follicles. Systemic antibiotic is a common therapeutic modality, so bacterial resistance can be a problem. Objectives: Assessment of Propionibacterium resistance to erythromycin, tetracycline, clindamycin and spiramycin. Patients and Methods: Sampling was done on lesions of 123 patients with acne vulgaris who...
