Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...

Advanced seismic slope stability analysis
(Springer Verlag, 2013)
The objective of this study was to present an advanced methodology for assessing seismic slope stability by taking into account the uncertainties related to the main input parameters. The methodology was applied on a real ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
Mars evelope simulation in a high-performance human centrifuge
(International Astronautical Federation, IAF, 2013)
This paper represents an effort to enhance and contribute to the human exploration of Mars, by simulating phases of the Earth-Mars-Earth flight envelope in a high performance human centrifuge. Humans are the most valuable ...
Low-temperature convective drying of apple cubes
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The paper presents results of an experimental investigation of convective drying of Idared apple in full recirculation laboratory scale dryer. The experiments were conducted with cube-shaped apple samples (side length 10 ...
Experimental studies on active vibration control of a smart composite beam using a PID controller
(IOP Publishing Ltd, Bristol, 2013)
This paper presents experimental verification of the active vibration control of a smart cantilever composite beam using a PID controller. In order to prevent negative occurrences in the derivative and integral terms in a ...
Explicit parametric method for optimal spur gear tooth profile definition
(Trans Tech Publications Ltd, 2013)
The gear tooth profile has an immense effect on the main operating parameters of gear pairs (load capacity, working life, efficiency, vibrations, etc). In current engineering research and practice, there is a strong need ...
High reflectance as desired property of shining surface and undesired for laser welding in jewel production of 585 gold alloy
(Metalurgia International, 2013)
For most of golden jewels the desired property is the shining surface. From the other point of view, high level of shining leads to great reflectance of impinged beams from a surface. It means that when a laser beam is ...
