Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...
Biomasa u sistemu daljinskog grejanja u Negotinu / Biomass in the district heating system of Negotin
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2007)
Osnovni cilj ove studije je da demonstrira energetske, ekonomske i ekološke koristi supstitucije klasičnih energenata obnovljivim izvorima energije i sistemima centralnog (daljinskog) grejanja. Gotovo 40% teritorije opštine ...
Kinetic phenomena in charged particle transport in gases, swarm parameters and cross section data
(IOP Publishing Ltd, Bristol, 2007)
In this review we discuss the current status of the physics of charged particle swarms, mainly electrons. The whole field is analysed mainly through its relationship to plasma modelling and illustrated by some recent ...
Exponential tracking control of an electropneumatic servomotor
(Automatic Control and Computer Sciences, 2007)
The new definition of practical exponential tracking is shown. Practical tracking is defined by the output vector, which is different from former definitions, given by the output error vector. Defined exponential tracking ...
The application of laser beam diffraction and scattering methods in the measurement of shape and determination of material parameters
(Lasers in Engineering, 2007)
Lasers can be used for many applications including determination of size, in addition to the theory of diffraction and material dispersion phenomena. In this paper we calculated the corrections in angular intensity for the ...
Virtual consultant in welding - Creation of the content server
(Welding in the World, 2007)
In situations where the end users have no domain experts, a virtual consultant in a form of a software surrounding based on updated internet technologies may often show to them the procedure to follow in a given situation ...
Aging of solar cells under working conditions
(National Institute of Optoelectronics, 2007)
Rapid development and wide application of photovoltaic (PV) solar systems are primarily based on thorough investigations of the characteristics of solar cells. Though proved to be relatively stable (except perhaps amorphous ...
Fatigue properties of a high-strength-steel welded joint
(Institute of Metals and Technology, 2007)
In addition to the strength and toughness properties, the fatigue properties of welded joints are necessary for the design of high-strength steel structures exposed to variable loading. Wohler curves were determined for ...
