Abstract In preparation for the High Luminosity LHC (HL-LHC) runs, ATLAS inner detector will be completely replaced with an all silicon Inner Tracker (ITk). Hybrid pixel modules used innermost tracking layers, and micro-strip detectors outer layers of tracker. During production detector, sensors, readout electronics, other components undergo a series quality control (QC) assurance tests. Defect...

Kulik T. A. Investigation of the temperature factor on formation a strip surface micro-relief during warm rolling
 The is studied as that affects strip, which was rolled with heat. Various schemes for heating to required are considered. A mathematical model distribution over thickness and along length deformation zone obtained. height not same. Our studies have shown scheme better when hea...

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 ...

Abstract As one of the very common industrial products, strip steel plays a important role in various fields. Steel production has received extensive attention. In production, scratches are unavoidable due to numerous forces beyond human control. Cracks and other flaws appear, their presence direct impact on product’s quality. Therefore, it is great significance develop efficient accurate surfa...

Pulsating convective models and evolutionary tracks are used to constrainmass, luminosity, and effective temperature of metal-poor (Z in the range of 0.0001 to 0.001) low-mass (0.52M –0.80M ) fundamental pulsators connected with the horizontal branch and asymptotic branch phase. On this basis the fundamental period P (F ) and the absolute blue magnitudeB of the pulsators are calculated. We show...

We present and discuss theoretical predictions concerning the pulsational properties of Classical Cepheids. Masses and luminosities provided by stellar evolutionary calculations are used as input parameters of nonlinear, nonlocal and time–dependent convective pulsating models and accurate determinations of both the blue and red edge of the instability strip are derived, together with theoretica...

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...
