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 ...
Upravljanje rizikom mašina u otvorenim rudničkim kopovima / Risk management of machines in open pit mines
(Institut za ispitivanje materijala, Beograd, 2013)
Fenomen rizika treba najpre definisati, a da bi se njime upravljalo, potrebno ga je i meriti. Merenje je neophodno da bi se utvrdili ciljevi koji se žele postići i stepen ostvarenja ciljeva. Merenje može biti kvalitativno ...
Improving structure dynamic behaviour using a reanalysis procedures technique
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
The present paper deals with the problem of improving dynamic characteristics for a sub-structure of bucket wheel excavator. The procedure is concerned with the analysis of the distribution of potential and kinetic energy ...
Structural integrity assurance of casing pipes in the oil and gas industry
(WIT Transactions on the Built Environment, 2013)
The exploitation of casing steel pipes used in oil and gas drilling rigs typically involves a corrosive atmosphere, high pressures and elevated temperatures. These conditions can affect the initiation and development of ...
Redesigning components of power transmission according to numerical model and vibration diagnostics
(Journal Vibroengineering, Kaunas, 2013)
This article presents derived methodological procedure of redesigning shaft, gear box, bucket wheel of bucket wheel excavator. Method of finite elements has been used for defining numerical model of shaft. As validation ...
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 ...
Elementi modifikacije i osetljivosti dinamičkih parametara / Elements of dynamic parameters modification and sensitivity
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
Promene na konstrukcijama mogu izazvati promene u strukturnim matricama nekih elemenata. U zavisnosti od vrste konstrukcije, kao i od željenih promena u njoj, moguće je menjati veću ili manju grupu elemenata. U ovom radu ...
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 ...
Metodološki pristup proceni integriteta i veka rotacione opreme u hidroelektrani - turbinsko vratilo / Methodological approach to integrity assessment and service life of rotating equipment at hydropower plant: Turbine shaft
(Institut za ispitivanje materijala, Beograd, 2013)
Horizontalne Kaplanove turbine su instalirane u hidroelektrani 'ĐERDAP 2', 10 jedinica ukupne snage 28 MW. Uzimajući u obzir činjenicu da se zamor pojavio u mnogim komponentama, sprovedeno je istraživanje uticaja režima ...
