Logistics in European Traffic Policy

Modular concepts and logistics centers are the basic instruments for improving resource utilization in European transport system. Efficacy of the system and integration of transport services are not as advanced as they could be. Europe needs efficient logistics of freight traffic together with the combining of all aspects of traffic in order to retain and improve its competitiveness and progress in conformity with Lisbon co-modality programme and concept. Rapid development of freight traffic and congestion, accidents, noise and pollution, all the consequences of this rapid development, present economic, social, and ecological problems that have to be solved. Efficient planning, managing and control of transportation system are not yet developed enough. It is necessary to introduce modern logistics solutions in order to use less transport operations for transporting more goods.logistics, logistics centers, multimodality, ecology, traffic.

Sistem za praćenje zagađenja vodotoka usled nekontrolisanog ispuštanja otpadnih voda sa plovila i splavova

Vessels and floating boats, specially boat – restaurants, are source of sanitary waste waters which are more and more dangerous for water streams. As part of the technological development project, system for redox potentials and waste substances concentration monitoring system in natural aquatic surrounding was made. Therefore, appropriate software packages for monitoring, registration and archiving of results measured by sonda, located on a floating boat on adequate location of river Sava for relevant measurements, were developed. This article presents system characteristics, software and hardware, as well as information and communication model that are used by relevant local, regional and national monitoring staff.Plovila i splavovi, a posebno splav-restorani, predstavljaju izvor otpadnih voda koje sve više zagađuju vodotoke. U okviru projekta tehnološkog razvoja osmišljen je sistem za praćenje promene koncentracije odgovarajućih zagađujućih supstanci i redoks potencijala u prirodnoj akvatičnoj sredini. U tu svrhu su razvijeni odgovarajući softverski paketi za monitoring, registrovanje i arhiviranje rezultata merenja, ostvarenih pomoću sonde, postavljene na splav koji se nalazi na podobnoj lokaciji na Savi za dobijanje relevantnih rezultata. U radu su prikazane karakteristike sistema, hardvera i softvera, kao i model informisanja i komunikacije sa relevantnim korisnicima rezultata monitoringa na lokalnom, regionalnom i nacionalnom nivou

Development a micro hydro power scheme at the weir on Black Timok

The micro hydro power scheme (MHPS), as a practical realization of research project supported from Ministry of Science of the Republic of Serbia, is presented in the paper. MHPS was constructed on the Black Timok (East Serbia) at the deserted weir. MHPS can be used as a model for other similar sites with extremely low head. On this way, the contribution to approaching to Directive EU for renewable energy sources was done. The results of project are summed in the paper. The method of turbine type selection by use of nomogram is presented. The results of dimensions scaling of existing smaller turbine are given. On the base of these results, the turbine of 5 times higher dimensions was designed and made. The results of estimation and measuring the parameters of this turbine are compared. Designed and constructed powerhouse of MHPS, which is jointed to existing weir, is described. The results of energy efficiency and ecological effects analysis of MHPS are given in the paper

Solution of Optimal Reactive Power Dispatch by a Hybrid GSA-SQP Algorithm

The optimal reactive power dispatch (ORPD) is achieved by optimal coordination of the equipment which control the reactive power flows in the power system. The (ORPD) can be mathematically formulated as a nonlinear, static and large-scale optimization problem with constraints. This paper deals with solving the ORPD problem using a new hybrid algorithm consisting of gravitational search algorithm (GSA) and sequential quadratic programming (SQP). The performance of this hybrid algorithm for the ORPD problem is studied and evaluated on the standard IEEE 30-bus test system with two different objective functions, namely minimization of real power loss and voltage profile improvement
