Microheaters for copper oxide-based gas sensors

ABABII, Nicolai; TROFIM, Viorel; LUPAN, Oleg (Tehnica UTM, 2020)

This paper describes two procedures developed for obtaining microheaters for copper oxide-based gas sensors. Different types of substrates (glass, SiO2/Si and ceramic) are investigated, as well as different configurations ...
Characteristics of quantum dots laser subjected to conventional and filtered optical feedback

RUSU, Spiridon; CHISTOL, Vitalie; TRONCIU, Vasile (Tehnica UTM, 2020)

The quantum dots laser under the influence of conventional and filtered feedback is analyzed in the framework of the extended Lang-Kobayashi rate equations. The feedbacks comes from two separate branches: conventional and ...
Stochastic optimal control of a two-dimensional dynamical system

LEFEBVRE, Mario (Tehnica UTM, 2020)

In this paper, we considered the problem of optimally controlling a twodimensional dynamical system until it reaches either of two boundaries. We consider a controlled dynamical system (X (t), Y (t)) which is a generalization ...
The performance of different vertical axis wind turbines with J-shaped blades

RABEI, Ivan (Tehnica UTM, 2020)

This study is focused on the aerodynamic optimization of Vertical Axis Wind Turbines' blades. A special feature was investigated – the opening at the blade’s trailing edge (opened blades). The blades having this element ...
Stability of ascorbic acid during the technological processes of apricot compote fabrication

PATRAS, Antoanela; BAETU, Alina Loredana; BAETU, Marius (Tehnica UTM, 2020)

Peculiarities of walnut oil state in some food emulsions

RADU, Oxana (Tehnica UTM, 2020)

The replacing of traditional lipids with more health-promoting oils containing polyunsaturated fatty acids (PUFA) is a modern trend in food industry. The principles of emulsions formation containing walnut oil (up to 90% ...
Drying installation for granular products in the suspension layer

BALAN, Mihail; BERNIC, Mircea; ŢISLINSCAIA, Natalia (Tehnica UTM, 2020)

One of the main problems of wet plant products drying processes is the long duration of thermal tartarization, which consequently leads to the diminution of the quality indices. This problem is exacerbated in the case of ...
