  • Some properties of Neumann quasigroups 
    DIDURIK, Natalia (Bons Offices, 2018)
    Definition 1. Quasigroup (Q, •) is unipotent if and only if x • x = a for all x ∈ Q and some fixed element a ∈ Q. Definition 2. Quasigroup (Q, •) has right unit element (a right unit) if there exists element e (unique) ...
  • Spectral Collocation Solutions to Eigenproblems on Unbounded Domains 
    GHEORGHIU, Călin-Ioan (Bons Offices, 2018)
    The aim of this communication is to argue that spectral collocation based on Laguerre (LGRC), Hermite (HC) as well as Sinc (SiC) functions offers reliable and accurate solutions to a large class of eigenvalue problems on ...
  • Splines for the Set Functions 
    POSTOLICĂ, Vasile (Bons Offices, 2018)
    Following the multiple possibilities to approximate any set function using proper sequences of countable additive set-functions and our main conclusions given in concerning the best approximation, we present the adequate ...
  • Subnormalizing Extensions and D-structures 
    COJUHARI, E. P.; GARDNER, B. J. (Bons Offices, 2018)
    In this talk all rings have identity but need not be commutative. In many cases the ring A(G; σ) is a subnormalizing extension of A generated by G. On the other hand, if S is a subnormalizing extension of R, the xi form a ...
  • The sufficient center conditions for a class of bidimensional polynomial systems of differential equations with nonlinearities of the fourth degree 
    CALIN, Iurie; CIUBOTARU, Stanislav (Bons Offices, 2018)
    In this paper we consider the class of systems (1) (or (2)) with the conditions I3 = 0, I1 =0, I2 > 0. The conditions I1 = 0, I2 > 0 mean that the eigenvalues of the Jacobian matrix at the singular point (0, 0) are pure ...
  • The sufficient center conditions for some classes of bidimensional cubic differential systems 
    CALIN, Iurie; BALTAG, Valeriu (Bons Offices, 2018)
    The definition of the transvectant of two polynomials is well known in the classical invariant theory. By using the transvectants for the system (1) the following GL(2, R)-invariants were constructed.
  • Synthesis of the minimum variance control law for the linear time variant processes 
    COJUHARI, Irina; FIODOROV, Ion; IZVOREANU, Bartolomeu; MORARU, Dumitru (Bons Offices, 2018)
    Above the linear process can act the disturbance signals, so kind of processes can be described by the parametrical models, where the most used take part from the ARMAX class (Auto-Regressive Moving Average with eXogenous ...
  • Topological configurations of singularities for quadratic differential systems 
    ARTES, Joan C.; LLIBRE, Jaume; SCHLOMIUK, Dana; VULPE, Nicolae (Bons Offices, 2018)
    In this paper we extract the local topological information around all singularities from the 1879 geometric equivalence classes. We prove that there are exactly 208 topologically distinct global topological configurations ...
  • Utilizarea proprietăților modulului la rezolvarea inecuațiilor ce conțin simbolul lui 
    CORLAT, Andrei; JARDAN, Ion (Bons Offices, 2018)
    În această comunicare sunt analizate metode de rezolvare a inecuațiilor algebrice ce conțin simbolul modulului, bazate pe utilizarea proprietăților lui, ceea ce permite rezolvări succinte. De regulă, inecuațiile ce conțin ...
  • Ways of resource virtualization for HPC Cloud Systems 
    ANTOHI, Ionel (Bons Offices, 2018)
    Cloud computing means the convergence of two major trends in today’s IT: efficiency - where the power of modern computers is more efficiently used through a high scaling of hardware, software and business agility resources ...
  • Weak solutions for a class of higher-order PDEs 
    BOUREANU, Maria-Magdalena (Bons Offices, 2018)
    We are concerned with the weak solvability of a class of fourth-order elliptic problems involving variable exponents. In the qualitative study of PDEs, the impact of an exponent that varies has been intensively investigated ...
