A Hybrid Interval Type-2 Fuzzy DEMATEL-MABAC Approach for Strategic Failure Management in Automotive Manufacturing
In the context of today’s rapidly evolving automotive market, improving the reliability and efficiency of manufacturing processes remains a critical challenge for industry players. This study introduces a hybrid multi-attribute decision-making model that integrates Failure Mode and Effects Analysis (FMEA) with interval type-2 fuzzy set theory to classify and prioritize process failures. The approach enables the FMEA team to systematically identify and rank failure modes, facilitating the time...

PARAMETARSKE ANALIZE FOTONAPONSKOG SISTEMA NA BRODU
U cilju zaštite životne sredine i smanjenja emisije štetnh gasova u pomorstvu Međunarodna pomorska organizacija (International Maritime Oraganization - IMO) je uvela zahtjeve energetske efikasnosti za brodove, koji se uglavnom odnose na smanjenje potrošnje goriva. Povećanje cijene goriva kao i primena različitih propisa koji definišu ograničenja emisija štetnih gasova u atmosferu i sankcije za njihovo nepoštovanje doveli su do intezivnije primene fotonaponskih sistema na plovilima. Primjena ...

ESTIMATION OF SOLAR IRRADIANCE ON TILTED SURFACE FACING SOUTH IN ČAČAK, SERBIA
The performance of solar systems is affected by the value of its tilt angle with respect to the horizontal surface, where the variation of tilt angle changes the amount of incident solar radiation. In this paper, hourly extraterrestrial solar irradiance, beam, diffuse and solar radiation on the tilted surface is modeled and calculated based on measured data of the global solar radiation on horizontal surfaces for Čačak (lat 43.87° N, long 20.33° E). The computer program has been done to ...

Commissioning Of ABB Collaborative Robot
The aim of this paper is to show the basic steps that are necessary to put new laboratory gear into operation. The laboratory setting is described. ABB RobotStudio was used to create a virtual laboratory by adding an ABB IRB 14000 robot to the work area, a virtual controller, and a simple program for manipulating the workpiece from one side to another with a change of arms. Simulation of the program was done. The commissioning of a robot on a real platform in the laboratory has been done.

Application Of Active Condensation Systems For Utilizing The Higher Heating Value Of Fuels
Aiming for a more energy-efficient use of energy also requires utilizing a higher heating value (HHV) of fuel. In systems where consumers of thermal energy with a temperature lower than ~50 °C are present, HHV is used directly by flue gas condensers or water spray exchangers. HHV is directly used in vapour pump boilers. In conditions without low-temperature consumers, it is necessary to raise the heat of vapour condensation in the flue gas to the consumer's temperature. This case occurs in ...

Global solar radiation prediction using Artificial Neural Networks
Upotreba obnovljivih izvora energije je u stalnom porastu jer se rezerve neobnovljivih izvora smanjuju a nivo zagađenja životne sredine dostiže razmere koje značajno utiču na kvalitet života. Zbog praktično neiscrpne količine energije Sunčevog zračenja, tehnologije za njeno korišćenje su u stalnom razvoju. Decenijama se energija Sunca koristi za generisanje toplotne i električne energije. Uprkos značaju poznavanja intenziteta Sunčevog zračenja broj meteoroloških stanica koji meri intenzitet...

Temperature measurement and current determination of horizontally and vertically placed low-voltage single core cable
This paper presents a procedure for measurement of surface temperature of a low-voltage single-core power cable with PVC insulation. Measurements were performed with the cable set into horizontal or vertical orientation, freely in the air. Three values of loading current of cable were used for measurements made in laboratory conditions. The current and the temperatures were measured during experiment. Measured cable temperatures were used for calculation of loading current of the cable and th...

Comparative Analysis Of Digital Signatures Based On RSA Cryptography And Elliptic Curve Cryptography
Elliptic curve cryptography (ECC) as one of the most advanced cryptosystems is being used by many applications for encryption, public key exchange and digital signatures. The strength of this type of cryptography is in the significantly increased difficulty of solving the problem of discrete logarithm due to the replacement of numbers multiplication by the operation of points "addition" on an elliptic curve, without affecting the key size. The application of RSA to digital signatures is a me...
