In the metal removal process industry, the current practice to optimise cutting parameters adopts a conventional method. It is based on trial and error, in which the machine operator uses experience, coupled with handbook guidelines to determine optimal parametric values of choice. This method is not accurate, is time-consuming and costly. Therefore, there is a need for a method...
In this paper, by applying the theory of condensing multimaps and the topological degree, we deal with the existence of solutions for boundary value problems with second order differential inclusions in different cases where the underlying space is a Banach space. Indeed, we investigate the existence of solutions for the BVP ( x ′′(t) ∈ F(t, x(t)) t ∈ I = [0,1], x(0) = x(1) = 0...
In this paper, we present a new approach to obtain the numerical solution of the linear twodimensional Fredholm and Volterra integro-differential equations (2D-FIDE and 2D-VIDE). First, we introduce the two-dimensional Chebyshev polynomials and construct their operational matrices of integration. Then, both of them, two-dimensional Chebyshev polynomials and their operational...
Interval matrices have many applications in intelligent engineering problems such as robotics in computer science. In this paper, we will first describe the concepts of interval matrices. Next, we will introduce a new class of interval matrices, namely, doubly stochastic interval matrices. Finally, we will present some properties of this new class of matrices.
The vibration of two curved nanobeams with coupling radial springs is considered. A nonlocal Euler-Bernoulli curved nanobeam model has been assumed in order to investigate the radial vibration of the double-curved-nanobeam-system (DCNBS) embedded in an elastic medium. Natural frequencies for the DCNBS are obtained by using the Navier Method. Moreover, the effect of the angle of...
A generalization of weighted, multiplier, controlled from frame and Bessel sequences to continuous g-frames and continuous g-Bessel sequences in Hilbert spaces is presented in this study. Moreover, we find a dual of a continuous g-frame in the case that the multiplier operator is invertible. Finally, it is demonstrated that a controlled continuous g-frame is equivalent to a...
In this paper, the concept of a soft MV -module is introduced and some examples are provided. Then, different types of intersections and unions of the family of soft MV -modules are established. Moreover, the notions of soft MV-submodules and soft MV -module homomorphisms are introduced and some of their properties are studied.
In this paper, we define A p,q(.) w,ϑ (R n ) to be space of the intersection of the spaces L p w (R n ) and L q(.) ϑ (R n ). Also, we investigate some inclusions and embedding properties of the space. Moreover, we discuss other basic properties of A p,q(.) w,ϑ (R n ).
In this paper, we use Hopf-Cole transform to solve conformable Burgers’ equation. After applying Hopf-Cole transform to conformable Burgers’ equation, we achieve conformable heat equation. Subsequently by using Fourier transform we have the exact solution of conformable Burgers’ equation with fractional order
A new stepwise method for solving optimal control problems is introduced. The main motivation for developing this new approach is the limitation of the continuous-time Pontryagin Maximum Principle (PMP) where all control functions must be continuous. However, in many real-world applications such as drug injection or resource allocation problems, it is not practical to...
Different range-free algorithms are proposed for location estimation in Wireless Sensor Networks. In these algorithms, the network is assumed to have no error and false data. This article attempts to evaluate and compare the effect of malicious data produced by node compromised attacks in some of the range-free algorithms: DV-hop, LSVM, and NN. The false data may be produced by...
In this paper, we introduce the concept of hyper lattice implication algebras which is established by combining the concept of hyper lattices and hyper implication algebras. We give some important examples of hyper lattice implication algebras and obtain some of their properties. Then, we characterize hyper lattice implication algebras in which 1 is an implication scalar element...
AutoCAD is one of the widely used software tools in engineering education. In this study, a general assessment of AutoCAD for the usage in the mechanical engineering technical drawing education is made.

In this manuscript, we use a specific definition of a fuzzy topological space. We define some basis structures of this topology and survey properties of them such as the concepts of F-closure, F-interior and F-limited points of a fuzzy subset of a topological space. Moreover, we redefine the concepts of the basis and subbasis of this topology and discuss about continuous related...
The subject of this paper is the efficient computation of lane change trajectories for self-driving vehicles. The paper first identifies that a certain type of clothoid-based bi-elementary paths can be used to represent lane change trajectories for vehicles. It is further highlighted that the curvature of such trajectories must be adjusted to the driving situation in order to...
A bounded linear operator T on a separable Hilbert space H is called hypercyclic if there exists a vector x ∈ H whose orbit {T n x : n ∈ N} is dense in H . In this paper, we characterize the hypercyclicity of the weighted composition operators Cu,ϕ on ℓ 2 (Z) in terms of their weight functions and symbols. First, a necessary and sufficient condition is given for Cu,ϕ to be...
The aim of this work is the solid oxide fuel cell (SOFC) thermodynamic study. Particular attention is given to the electric power optimization. The Nernst potential and the over-potentials that are due to the concentration polarization, activation polarization and to the Ohm polarization represent the fuel cell potential. A FORTRAN language program was developed locally for the...
