Strain gauges are used in different areas, especially in thedesign and development of new technical constructions andmode/testing. Also, strain gauges are inc01porated in the functionalpart of many instruments and devices. They are mostlyused as sensors in transducers designed to measure such mechanicalquantities as forces, moments, pressures, accelerations,etc. They have an important role in shipbuilding and marinetransport in general. In this paper we have suggested andshown an approach to the identification of strain gauge thermaloutput curve on the example of a product available at themarket. Neural network simulated in MatLab has been applied.The neural network has been adapted to simulate a realsystem with 1 o-9 order of magnitude error_ As it is well known,strain gauges measure deformations of 1 o-o order of magnitude.It is obvious that the network eJTOr cannot influence the measurementresults because of its being smaller by three orders ofmagnitude.

The paper deals with the ADSL (Asymmetric Digital SubscriberLine) technology- the asymmetric digital telecommunicationtechnology. It is characterised by high-speed transmissionof data and simultaneous transmission of information regardingthe throughput capacity of the telephone network. Thisresults in better efficiency of transmission, and higher utilisationof the bandwidth. Due to its advantages, the use of ADSLtechnology is increasing daily, especially by ente1prises in Europeand worldwide.

By analysing the cwTen.t situation on the Croatian transportationmarket, and considering all parameters needed forthe development of combined transport, measures are suggestedin order to improve and stimulate its development. Oneof the first measures is the standardisation and introduction ofunique tariffs for combined transport, and then government incentivefor the organisation and development of combinedtransport means and equipment. A significant role in thisshould be set on adequately defined transport policy.

If we acknowledge the role of traffic as active leaderof the sustainable economy development, then we certainlyhave to analyse the environment in which the traffic exists asa system, and therefore we have to foresee its limits which aredetermined by the specifics of the traffic system. Representingthe circulation system of economy, traffic has to eavesdrop onthe demands of the market, and has to be transformed andmodernised. The experience gained by working on the projectsand the studies related to business organisation resulted inthe conclusion that the requirements related to logistics inthe nineties were significantly greater than had been thecommon target until then -reduction of costs. In order to adjustcompletely to the market demands, with the help of advancedinformation technology, the companies apply logisticsas tools of competitiveness on the market. Extraordinmyachievements of IT, using of virtual reality enable businesspeople to communicate and contract businesses without beingphysically present. What is it that makes some companies moresuccessful than others? It is obviously a question of the advantagesof distribution realisation due to the fact that nowadayspurchase and selling are run globally in the world. The distributionof products at the right time, to the right place, at a pricewhich is favourable both to the seller and the buyer, in the rightmanner and in the appropriate quantity in the marketing senseis the prerequisite for the business success as element of businesslogistics. The development of this tool must be basedon the monitoring of the needs for the logistics managementand the tactical adaptability of the company. The solution oflogistics management of business processes must satisfy thecurrent and future customers' requirements in order to be competitive.

The article calls our attention to the existing dangers of potentiallyharmful 01ganisms being introduced in our sea withships ballast water and to the need of having this maller undercontrol. To this end the article presents the importance of ballastwater for a ship, organisms in ballast water, some cases ofharmful introductions and the case of Slovenia. Furthermore,legal aspects, ballast water management methods/techniquesand monitoring aspects are presented. Finally, the article dealswith perspectives for the regulation of the ballast water issue.

Traffic congestion is one of the major problems in most cities.It is the consequence of unavoidable motorization, butalso, in many cases, of improper solutions considering constructionof roads or organisation of traffic.This paper deals with one problematic crossroad in thetown of Zadar in which traffic jams occur due to poor organisationof traffic. Using mathematical simulation, the first partproves that traffic jams will certainly occur, and in the secondpart, crossroads signalling is considered as a possible solutionwhich, if combined with intelligent control could significantlyimprove the organisation of traffic at this crossroads.
