Is the war over? Is its success measured by the number of victims or the consequences it has caused? Is art the only winner of any war because it is the only one showing both sides of the coin? It is ideologically colored, but not conflicted. It is rebellious, but not destructive. It is a luxury of leisured, but not just the empty decoration. It is...

Energy efficiency is one of the priorities defined in the Energy Sector Development Strategy of the Republic of Serbia. For the successful realisation of any strategy, including energy sector development strategy, it is necessary to allocate financial resources. In the times recession and limited state budgets, it became necessary to look for new m...

One of the most significant contributors to the heavy metal concentration growth, especially lead metal concentration growth in the soil is traffic. The main objective of the study was to determine the lead content and its concentration in water of soluble and interchangeable forms of lead on the M-17 road in Mostar has been done. Observing this ro...

A Blatina grapes is fruit crop characteristic of the Herzegovina region. The amount of grapes produced for consumption and processing, greatly exceeding the Herzegovina population needs, and produced fruit has an impact on the quality of the diet to a wider geographical area. The aim of this work is to determine the content of zinc (Zn), as microel...

The main goal of this paper was to obtain all acceptable locations for siting of wind turbines in the region of Central South Serbia. One of the possibilities to increase the rentability of the wind farm is to reduce the transport loses, using produced energy as close to the production site as possible. The estimations were obtained using the WAsP ...

The basic idea of inverse optimal control theory for nonlinear systems is to find a feedback control law based on a priori knowledge of a Control-Lyapunov function (CLF), that leads to Lyapunov stability of the system and minimizes a cost functional [1], [4]. The problem of inverse optimal control leads to the Hamilton-Jacobi-Bellman (HJB) equation...

This paper presents a study of the fuel cell system performance operating at low pressure. A polymer electrolyte fuel cell (PEMFC) is analyzed in according with the possibility of using in transport applications. So, it begins with the description of a parametric model of the fuel cell which has been developed using a combination between empirical ...
