Consider a matrix valued function A(x) ∈ R, m ≥ n, smoothly depending on parameters x ∈ Ω ⊂ R, where Ω is simply connected and bounded. We consider a technique to locate parameter values where some of the q dominant (q ≤ n) singular values of A coalesce, in the specific case when A is large and m > n ≫ q. Notation. An m × n real matrix is indicated with A ∈ Rm×n. We always consider the 2-norm f...

Big data mining is a promising technology for industrial applications such as business intelligence and marketing. In this paper, we attempt to transfer this background to a scientific domain, which is problem solving. An enormous research investment has been done over the past years for solving NP-complete problems. The exact methods yield the optimal solution if it exists but they are not abl...

In the past decade wind-based electricity generation has grown rapidly, and is likely to grow even more in the future. Since generation sites—wind farms—tend to be remote, they require transmission lines to transport electricity to markets. These wind farms can be augmented by co-locating them with an electricity storage facility, for example, an industrial battery. This storage facility enable...

‎let $f$ be a proper $k$-coloring of a connected graph $g$ and‎ ‎$pi=(v_1,v_2,ldots,v_k)$ be an ordered partition of $v(g)$ into‎ ‎the resulting color classes‎. ‎for a vertex $v$ of $g$‎, ‎the color‎ ‎code of $v$ with respect to $pi$ is defined to be the ordered‎ ‎$k$-tuple $c_{{}_pi}(v)=(d(v,v_1),d(v,v_2),ldots,d(v,v_k))$‎, ‎where $d(v,v_i)=min{d(v,x):~xin v_i}‎, ‎1leq ileq k$‎. ‎if‎ ‎distinct...

We propose a method of developing multiscalar industrial policies based on spatially constrained clustering model which combines aspects complexity, relatedness and geography. Our formulation is motivated by recent developments economic complexity regarding the evolution output through interactions among industries within regions. This aims to aggregate set geographical areas into prescribed nu...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

This paper deals with the design and evaluation of a robust controller for static VAR compensator (SVC) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (SCIM) loads. The controller design is based on H∞ theory to deal with uncertainties arising in industrial network modelling. &#10The performance of the H∞ controller has been evaluat...
