In this paper, applying two theorems of Ricceri and Bonanno, we will establish the existence of three weak solutions for a quasilinear elliptic system. Indeed, we will assign a differentiable nonlinear operator to a differential equation system such that the critical points of this operator are weak solutions of the system. In this paper, applying two theorems of R...

in this paper, using a generalized translation operator, we prove theestimates for the generalized fourier-bessel transform in the space l2 on certainclasses of functions.

We consider the operator of generalized exponential ray transform whose values are initial data in emission computer tomography problem. establish connections between transforms different orders and obtain differential equations satisfied by transforms. prove uniqueness theorems for boundary value initial-boundary problems corresponding also discuss close with integral geometry tensor fields pr...

Tooth loss is one of the most common oral health problems, and may affect mastication, phonetics, aesthetics, quality life. Dental implant placement an effective procedure to replace tooth loss. techniques using freehand surgery procedures increase potential failure related position, angle, depth insertion with 6.42% prevalence. The accuracy installing dental implants through protocol depends o...

In this paper, a multilevel architecture able to interface an on-board computer with generic UAV flight controller and its radio receiver is proposed. The board exploits the same standard communication protocol of controllers can easily access additional data, such as: (i) inertial sensor measurements coming from multi-sensor board; (ii) global navigation satellite system (GNSS) coordinates; (i...

In this paper, we give the spectral theory for eigenvalues and eigenfunctions of a boundary value problem consisting of the linear fractional Bessel operator. Moreover, we show that this operator is self-adjoint, the eigenvalues of the problem are real, and the corresponding eigenfunctions are orthogonal. In this paper, we give the spectral theory for eigenvalues and eigenfunctions...

in this paper, we find explicit solution to the operator equation$txs^* -sx^*t^*=a$ in the general setting of the adjointable operators between hilbert $c^*$-modules, when$t,s$ have closed ranges and $s$ is a self adjoint operator.

We consider the transitive linear maps on the operator algebra $B(X)$for a separable Banach space $X$. We show if a bounded linear map is norm transitive on $B(X)$,then it must be hypercyclic with strong operator topology. Also we provide a SOT-transitivelinear map without being hypercyclic in the strong operator topology.
