ANALYSIS OF THE SERBIAN PUBLIC PRIVATE PARTNERSHIP PROJECTS IN THE FIELD OF ENERGY EFFICIENCY
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...

ART AS A RESULT OF THE IDEOLOGY OF POWER
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...

Analysis of Central Southern Serbia Wind Energy Potentials
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 ...

Applying Taguchi Method to Control the Thermal Expansion Effect on Machining Process of Aluminum Alloy Extruded Profile
In this paper we present a technological problem encountered in the machining accuracy of the parts for aerospace, made of aluminum alloy extruded profile with 7 meters length. Those parts have very tight tolerances and on milling process appears deviation due to thermal expansion effect, which influences the repeatability of machining processes. T...

Applications of the Thermoelectric Energy Harvester in Air Conditioning Condenser Unit
The devices that convert heat into usable electricity and use the three established thermoelectric effects known as the Peltier, Seebeck and Thomson effects are thermoelectric generators (TEG). These devices can generate power how long as there is a heat source. TEGs are made from thermoelectric modules and the cost of this modules is high, but the...

Angle Position Influences Over External Magnetic Field of a Solenoid in Wireless Power Transfer
The general form of the Biot-Savart law is referring to a closed loop, but it can be integrated over a finite length solenoid to calculate the external magnetic field in a specific point, at a rated distance from the center. The law states that the point of measure must be on the longitudinal axis of the solenoid. In real cases the point of measure...

A Mathematical Model for Inverse Optimal Control to Achieve Stabilization and Trajectory Tracking for Mobile Robots
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...

Analysis of a PEMFC System for Automotive Applications
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 ...
