The reinterpretation of classical art into digital art was taken as the basic framework within which I moving with using two concepts: classic and digital. Both terms represent different epochs, in which the notion of classical art implies a much longer period of time, making it more difficult to use without opting for a shorter period of tim...

 This paper discusses the selection of the most technically suitable method of transporting lime powder within the existing plant at the lime factory. From the production line, lime powder must be transported to the factory silo. Of the more technically feasible variants analysed, flying pneumatic transport was chosen as the most favourable va...

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 ...

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...

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...

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...

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 ...

Modern processing is a combination of individual production cell, designed to complete the business of manufacturing parts of subassemblies and their integration into the final product of the product. The success of such a system depends on stability operations while minimizing the possible errors in the system. The continuous monitoring system is ...
