In this paper it is proposed the displacement control of a bearingless induction machine (BIM) with split winding and optimized drive structure using Active Disturbance Rejection Control (ADRC). Considering that BIM multivariable, nonlinear, time-varying system coupled variables, advanced techniques can be useful in order to make operate efficiently good dynamic performance. The ADRC considers ...

In this note, we present a simple geometric argument to determine a lower bound on the split rank of intersection cuts. As a first step of this argument, a polyhedral subset of the lattice-free convex set that is used to generate the intersection cut is constructed. We call this subset the restricted lattice-free set. It is then shown that dlog2(l)e is a lower bound on the split rank of the int...

In geometry, students are frequently required to split their attention across verbal and visual information. We measured the impact of the split-attention effect on geometry problem solving by analyzing log-file data generated by students who used two versions of Carnegie Learning’s intelligent tutoring system for geometry. The original version split students’ attention across a table and diagr...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

A programmed temperature vaporizer (PTV) injection technique has been recently implemented in our laboratory. In present paper its performance is compared with other GC injection techniques commonly used in trace analysis of organic contaminants. Twenty-six pesticides representing different chemical classes were selected for the study. This group comprised compounds typically subjected to discr...

Introduction Metamaterials are artificial composites whose electromagnetic properties can be engineered to achieve phenomena not observed in natural materials [1]. They are usually manufactured by means of the repetition of resonant elements to constitute a periodic structure and an essential characteristic is that an effective permittivity and permeability (μ) can be defined through the approp...

In this paper, a new computationally eecient algorithm for recursive least-squares (RLS) l-tering is presented. The proposed Split RLS algorithm can perform the approximated RLS with O(N) complexity for signals having no special data structure to be exploited, while avoiding the high computational complexity (O(N 2)) required in the conventional RLS algorithms. Our performance analysis shows th...

a study was undertaken to determine the effects of different biofertilizers on growth and seed barley, bahman cultivar in iran. the trial was laid out in rcbd with split plot arrangement having three replications during 2011-12 and at boroujerd, iran. treatments were three nitrogen biofrtilizers (nitroksin, nitrokara and supernitroplass) and three phosphate  biofrtilizers (phosphate barvar2, bi...

We have developed a biodegradable temporizing matrix (BTM) capable of supporting secondary split-skin graft-take in animal studies. We report its first long-term implantation and use as a dermal scaffold in humans. This preliminary study assesses its ability to integrate, its ease of delamination, its ability to sustain split-skin graft in complex wounds, the degree of wound contraction, and ul...
