This paper proposes a truly interactive virtual environment (VE) system for 2D assembly tasks at the microscale. It is based on the application of virtual potential fields as a control aid for performing safe and reliable path planning strategies. The planner covers a whole range of problems due to microscale effects in object assignment, obstacle detection and avoidance, path trajectory findin...

The paper presents experimental results on quadratic assignment problem. The “scanning area” method formulated for radioelectronic equipment design is applied. For all more complex tests ours results are better or coincident with the ones known in literature. Conclusion concerning the effectiveness of method are given.

russian language, with regard to its grammar, is a language with its own special complexities, hardly found in other languages. although languages are different from each other, they have some similarities as well. the iranian learner, while learning russian, analyzes the sentences using patterns similar to his/ her native language patterns. occasionally, such native patterns cause the learner ...

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.

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.

A recent topic in language acquisition is children’s comprehension of sentences containing multiple scope-bearing elements. The main problem posed by those sentences is that the relative scope of each operator might be reversed and children need to relate a single sentence to two distinct logic representations. Sometimes languages have means to reduce ambiguity, as in negative sentences, where ...
