Analysis of Srebrno Jezero Wind Energy Potentials
The main goal of this paper was to obtain all acceptable locations for siting of wind turbines in the region of Srebrno jezero lake, near the Danube river, near the borders with the neighbouring Republic of Romania and Republic of Bulgaria. Total of 10 locations for sitting of 2MW wind turbines were accepted. The estimations were obtained using the...

On Embedded Hypercubes in Extended Fibonacci Cubes
An important aspect of a distributed system regards the design of the communication subsystem meaning the design of its interconnection network. The design of the interconnection network suppose a compromise to achieve some objectives as: high transfer rate, small communication delay, simplicity, scalability, optimal rapport cost/performance. An in...

Valuation of coefficient of rolling friction by the inclined plane method
A major objective of tribological researches is characterisation of rolling friction, due to various cases encountered in classical engineering applications, like gear transmissions and cam mechanisms or more recent examples met in bioengineering and biomedical devices. A characteristic of these examples consists in reduced dimensions of the contac...

LabVIEW application for motion tracking using USB camera
The technical state of the contact line and also the additional equipment in electric rail transport is very important for realizing the repairing and maintenance of the contact line. During its functioning, the pantograph motion must stay in standard limits. Present paper proposes a LabVIEW application which is able to track in real time the motio...

Establish the CNC machining strategy in relation with geometric complexity of the parts made from 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 length up to 10 meters. Those parts have very tight tolerances and on milling process appear several factors that influence the repeatability of machining processes. Several factors must be c...
