in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...

This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

To improve the quality of surface loosening, it is necessary to search for new approaches soil maintenance and solving problems related reproduction fertility, maintaining production volumes. In this connection, in order increase operational reliability, simplify design clean teeth from weed stalks basic technical tool, which includes a frame form beam equipped with suspension system mounted te...

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work...

Design of modern timber floors is often governed by the vibration serviceability requirements. One way to improve through design two-way floor systems. In this paper, behaviour LVL–concrete composite plates and a plate strip investigated experimentally, with an emphasis on performance proposed dovetail joint for connecting adjacent LVL panels. The investigations consist experimental modal analy...

The formation of ripples along the edge of plant leaves is studied using a model of an elastic strip with spontaneous curvature. The equations of equilibrium of the strip are established in an explicit form. A numerical method of solution is presented and carried out. Owing to the presence of geometric nonlinearities, several equilibrium configurations are found but we show that only one of the...

Introduction: Microstrip have been developed due to specific features: high Q factor, low mutual coupling (often used at high field MRI for parallel imaging), and radiation losses are significantly reduced (which enhances SNR). Balanced feeding of the microstrip preserves the electrical symmetry with respect to the strip center, making the probe invariant under different loading conditions (dif...
