  • Reflective functors and factorization structures 
    CERBU, Olga (Technical University of Moldova, 2021)
    In the C2V category of locally convex Hausdorff vector topological spaces, some relationships between reflective functors and factorization structures are examined.
  • Reliability analysis of some complex systems with time redundancy 
    CORLAT, Andrei (Technical University of Moldova, 2021)
    In the process of elaboration of the mathematical models in the reliability theory, a wide class of random processes is used: Markovian processes, semi Markovian processes, regeneration processes, etc).
  • A simple ODE mathematical model to assess the effectiveness of facemask wearing in COVID-19 pandemic 
    BERINDE, Vasile (Technical University of Moldova, 2021)
    One of my first attempts when I start the ODE course(and later, the PDE course) is to try to persuade my students on how important are for science and technology the mathematical models builded by means of differential equations.
  • Sistem bazat pe tehnologii LABVIEW pentru predarea la distanţă a disciplinelor inginereşti 
    SUDACEVSCHI, Viorica; ABABII, Victor; MUNTEANU, Silvia; MELNIC, Radu; CARBUNE, Viorel (Technical University of Moldova, 2021)

  • Solving the non-linear transportation problem on network 
    PAŞA, Tatiana (Technical University of Moldova, 2021)
    In this paper we study the non-linear transportation problem on network. The aim of this paper is to propose algorithms that solve the problem.
  • Some aspects regarding torque study and elaboration of the blades orientation mechanism for microhydropower plant 
    BOSTAN, Viorel; BOSTAN, Ion; DULGHERU, Valeriu; CIOBANU, Oleg (Technical University of Moldova, 2021)
    In the following, we calculate the hydrodynamic coefficients for the reference profile NACA 0016 with length rope, for example c = 1,3 m.
  • Some particular cases for inverse operations in the class of preradicals in modules 
    JARDAN, Ion (Technical University of Moldova, 2021)
    Four new operations are introduced and studied in the class of preradicals PR in modules, namely, the inverse operations of the product and of the coproduct with respect to meet and to join.
  • State of infosecurity in the Republic of Moldova 
    BOLUN, Ion; CIORBA, Dumitru; BULAI, Rodica; CALIN, Rostislav; BODOGA, Cristina (Technical University of Moldova, 2021)
    The increasing severity of cybercrime and the rising complexity of cyberattacks accentuate the importance of research/development in infosecurity. Ensuring infosecurity is very complex, multidimensional and long-term and ...
  • STEAM education in search missions 
    AFANAS, Dorin; BRAICOV, Andrei (Technical University of Moldova, 2021)

  • Two parameter singular perturbation problems for sine-Gordon type equations 
    PERJAN, Andrei; RUSU, Galina (Technical University of Moldova, 2021)
    We obtain some a priori estimates of solutions to the perturbed problem, which are uniform with respect to parameters, and a relationship between solutions to both problems. We establish that the solution to the unperturbed ...
  • Unele aspecte ale integrării funcţiilor raţionale 
    CORLAT, Andrei; JARDAN, Ion (Technical University of Moldova, 2021)
    La integrarea functiilor rationale se utilizeaza metoda coeficientilor nedeterminati. De regula, se obtine un sistem de n ecuatii liniare (n≥2,nєN), care pentru un numar de coeficienti nedeterminati mai mare ca trei, ...
