This paper focuses on the exploration of the hill section of the Roman road that led from the settlement of Incero (the Požega basin) via Stravianis (around Našice) to Mursa (Osijek), which is mentioned in Roman itineraries as part of a regional road, Siscia – Mursa. Earlier researchers of this road report that the ancient road to the road station of Stravianis was routed through the Krndija Mountains, and is usually thought to be near Bedemgrad, i.e. Gradac Našički, as previous research found the largest concentration of Roman finds in its wider area. In order to investigate the spatial characteristics of that section of the route of the Roman road and why it was routed through this particular hilly area of Krndije, this paper applies the methods and tools used by landscape archaeology – more precisely, the capabilities of the geographic information system; within that system, we georeferenced the data from ancient sources, literature, and field surveys. We used the Least Cost Path algorithm to generate optimal routes between "key" points, which enabled the spatial analysis and prediction of the corridor in question. By applying this methodology, we obtained results based on specific spatial analyses, largely confirming earlier assumptions about the route and the location of the Roman road station of Stravianis, but also bring some new knowledge indicating the possibility that Romans could also use an alternative or more direct route towards Mursa that was not considered before, umjesto and the location of the Roman road station of Stravianis.

A research has been done in the form of a case study which analyses the situation and possibilities of the solid communal waste management system's assessment on the islands of Cres and Lošinj. The paper analyses a concept of waste disposal strategy through the transport to the central county landfill, and it gives an overview of the cost effectiveness and environmental impact of the possible industrial incineration of Cres and Lošinj's communal waste. A method of local carbon footprint for the environmental load determination has been used. Thus it has been calculated the partial ecological footprint of the possible solid communal waste's incineration. The share of tourism, as the booming and strategically most important industry on the islands, has been isolated within the carbon footprint. The main results has shown that soon after the first major investments in the industrial incineration of the communal waste, the positive characteristics of such waste management would become apparent. The research has shown that specific characteristics of island areas, such as annual trends of tourist activity and waste production, as well as the islands' bioabsorptive capacity, benefit this type of waste management. The communal waste incineration produces atmospheric emissions and solid residue which present unavoidable environmental load, and if the investing into the waste disposal management system is planned according to the high ecological standards, the footprint on the islands' environment would be acceptable and justified. The possible industrial incineration of waste which was analysed would generate thermal and electrical energy for the needs of the local population and economy, especially tourism. It should be noted that the above described system of waste management would increase for the future of the island very important energy self-sufficiency. [ABSTRACT FROM AUTHOR]

Cilj je ovoga rada pokazati da se primjenom teorije redova čekanja može odrediti optimalan kapacitet lučkoga kontejnerskoga terminala, odnosno kombinacija broja pristana i dizalica po pristanu s najmanjim troškovima za zadani promet. Kontejnerski terminal je sustav složen od određenog broja međusobno zavisnih podsustava pa se optimalan kapacitet terminala svodi na izračunavanje optimalnog broja pristana, budući da kapacitet pristana determinira potreban kapacitet ostalih podsustava, a time i propusnu moć kontejner-skog terminala u cjelini. Za dobivanje optimalnog rješenja primijenjen je model ukupnih troškova koji se temelji na teoriji redova čekanja. Model se može koristiti za bilo koji kontejnerski terminal te za terminale u sadašnjim ili budućim uvjetima. Dobiveni rezultati su baza za donošenje odgovarajućih poslovnih odluka vezanih za poslovanje terminala. Model je testiran na primjeru kontejnerskog terminala riječke luke Brajdica.

U radu su prikazani rezultati provedene simulacije i istraživanja isplativosti ugradnje turbogeneratora na brod. Analiza je provedena primjenom NOR Controlovog simulatora za simulaciju brodskog postrojenja tankera za prijevoz sirove nafte. Simulirana je proizvodnja električne energije s turbogeneratorom ili s di-zelskim generatorom. Analiza početnih investicijskih troškova provedena je anketom s proizvođačem brodskih generatora pare te s dobavljačima turbo i dizelskih generatora pri čemu su se koristile trenutne cijene teškog i lakog dizelskog goriva na svjetskom tržištu. Izračunate su uštede u slučaju kada se za proizvodnju električne energije koristi turbogenerator u paralelnom radu s osovinskim generatorom. Rezultati istraživanja pokazuju značajne uštede i neupitnost isplativosti ugradnje jednog takvog uređaja na brod, kao i opravdanost njegovog maksimalnog korištenja, ako je na brodu instaliran.
