Original scientific paper In this paper a systematic exploration of a typical two-stroke slow speed marine diesel propulsion shafting design space is performed. First, a set of the four most influential design parameters is defined, consisting of shafting stiffness, propeller, turning wheel and tuning wheel mass moments of inertia. Then, a full set of 625 design points is defined. For each desi...

Introduction. This article presents the development of mathematical models related to effect initial content dry matter, yeast, and yeast energizer on fermentation rate, alcohol content, matter in finished product – mead.
 Study objects methods. The were developed by using response surface methodology (RSM). contents tested concentration ranges 150–600 mg/L, 16.3–24.4%, 140–500 respectivel...
