A review of energy analysis simulation tools
(International Working Conference ’’Total Quality Management – Advanced and Intelligent Approaches’’, 4 th – 7 th June, 2013, Belgrade, Serbia, 2013)
Sustainable design is the philosophy of designing physical objects, built environment, and services to comply with the principles of social, economic, and ecological sustainability. The most widespread method for achieving ...
Multiple flow heat exchanger
(United States Patent Office, 2013)
Air conditioning cycle with CO2 refrigerant is dominantly transcritical. External heat exchanger (gascooler) encounters strong refrigerant temperature change. If the gascooler has two or more refrigerant passes, the problem ...
Color measurement of food products using CIE l*a*b* and RGB color space
(Consulting and Training Center KEY, 2013)
Color of the food is the first parameter of quality evaluated by consumers. What is important is the acceptance of the product even before being consumed. Inspection of food products is done using machine vision, particularly ...

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. ...
Stress-strain behaviour of laser welded stainless steel joints
(Croatian Society of Mechanics, 2013)
Numerical investigation of processes in the lignite-fired furnace when simple gray gas and weighted sum of gray gases models are used
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Comparison of the numerical investigation results was carried out when the simple gray gas (SGG) and weighted sum of gray gases (WSGG) models are used to model the radiative properties of the gas phase inside the lignite ...
Nanotehnološki materijali za konverziju sunčeve energije / Nanotechnology materials for solar energy conversion
(Contemporary materials, 2013)
Nanotehnologija je riječ koja se u današnje vrijeme često koristi, iako je samo prije 15 godina to bio dosta nejasan pojam koji se koristio gotovo isključivo u naučnim krugovima. Činjenica je da je nanotehnologija danas ...
