AN APPROACH TO ANALYSIS OF NON LINEAR CHARACTERISTICS OF MARINE ENGINE\u27S SPEED REGULATORS

Marine engine speed regulators have been observed as non-linear dynamics models, those mathematical characteristics are similar to system of differential equations. Theoretical and experimental analysis of such has been done, to comprise behaviours of regulator models. Mathematical approach to equation solutions is determined by well known methods of numeric integration, but approach to Runge-Kutta method was preferred to reach reliable values of unknown system variables. Computer simulation and computer-aided design is the best tool for system modelling representation. Therefore, an acceptable software algorithm has been presented to enable understanding of software simulated analysis, and to get numerical solutions of system equations

SYSTEM DYNAMICS MODELLING AND SIMULATION AS PART OF EDUCATION IN MARINE SCIENCE COLLOQUIUMS

By showing a characteristic theme of an educational unit, which is presented with the aid of a computerised simulation based on a mathematical model, a statement is illustrated claiming that utilisation of computers can shorten the time needed for presenting expert knowledge. At the same time, the quality and the clarity of the lecture is improved. A positive and a favourable boost to the student\u27s creative capabilities should be added

"THE TRAVELLER\u27S NIGHT-SONG" (II) BY J. W. GOETHE

Ovaj članak bavi se "Putnikovom noćnom pjesmom" (II) J. W. Goethea. Nastala je u jednom danu (6. IX. 1780.), napisana kredom na zid neke kolibe u brdima iznad gradića Ilmenaua, ona je primjer Goetheova "automatskog pisanja", anticipatorskog u odnosu na smjer koji će se pojaviti tek u prvoj polovici XX. stoljeća. Pisac ove kratke studije vidi stoga u njoj tragove Goetheova spontanog zen-osjećaja svijeta, odraz njegove podsvjesne težnje za nirvanom, otkriva sličnosti između te pjesme i stihova japanskog pjesnika Ryôkana. Posebna pozornost posvećena je odnosu "Putnikove noćne pjesme" (II) i Goetheove pjesme "Putnik". Biografski pristup kombiniran je s fenomenološkim, s osvrtom na analizu Vladimira Nazora koji u "Putnikovoj noćnoj pjesmi" (II) vidi odraz Spinozine filozofije, ali i natruhe Goetheova panteizma. Ovaj kratki rad posvećen je gđi prof. dr. Nevenki Košutić-Brozović.The paper discusses "The Traveller\u27s Night-Song" (II) by J. W. Goethe. Created in one day only (6th September 1780), and written on a wall of a mountain cabin above the small town of Ilmenau, it is an example of Goethe\u27s "automatic writing", anticipatory of a new trend which was to appear much later, in the first half of the 20th century. The author of this short research, therefore, finds in this poem traces of Goethe\u27s spontaneous zen-feeling of the world, a reflection of his unconsciuos longing for nirvana, and detects some similiarities between Goethe\u27s poem and some verses written by the Japanese poet Ryokan. Special attention is given to the relationship between "The Traveller\u27s Night-Song" (II) and Goethe\u27s other poem titled "Traveller". The biographical and phenomenological approaches here are combined and due consideration is given to Vladimir Nazor\u27s analysis, who, in this poem, finds a reflection of Spinoza\u27s philosophy and some elements of Goethe\u27s pantheism. This paper is a tribute to Professor Nevenka Košutić-Brozović
