This work addresses a scheduling problem arising from an application in a real industrial context, namely task scheduling in the cutting department of a clothing industry. In general, clothes are produced by assembling fabric cutouts. In the cutting department, fabric rolls on a line with a constant speed, and is cut by automated machines arranged along the line. Machines are all identical. A f...

The lateral buildup ratio (LBR) used to estimate the depth dose distribution of electron beams for an irregular cutout field was obtained for a 4-MeV energy beam from a Varian 21 EX linear accelerator. The depth-dose curves for a group of circular cutout fields starting from a 2-cm diameter were measured. Electron diodes were used in a large water tank to measure the LBR values for 6, 9, 12, an...

In dusty plasma experiments, the confining potential of the GEC rf Reference Cell is commonly assumed to be parabolic. There are various ways to test this assumption, many of which interfere with the plasma. We use the noninvasive method of perturbing a single particle suspended in the plasma with laser pulses. In this experiment a cw laser (532nm, 0.01.05W) supplied the radiation pressure forc...

A comparison of the buckling analysis of the nanoplate and nanocomposite plate with a central square hole embedded in the Winkler foundation is presented in this article. In order to enhance the mechanical properties of the nanoplate with a central cutout, the uniformly distributed carbon nanotubes (CNTs) are applied through the thickness direction. In order to define the shape function of the ...

Aircraft is a complex engineering structure. The safety of the structure and weight are two important aspects to be kept in mind while designing aircraft It an uphill task for structural designer bring out safest with minimum weight. current project deals stress analysis fuselage-stiffened panel without large cutout emergency exit door.

Introduction: In electron beam treatment, because of the non-point electron beam source, inverse-square law cannot be applied for dosimetry in different treatment intervals. Therefore, providing source-surface distance (SSD) charts in all clinics is of paramount importance. This study aimed to determine the effective SSD for various electron beam energies and field sizes and to...

In this work, finite element analysis has been done along with experimental test and conducted using numerical tests of the buckling response quasi-static compressive loading six layers woven cross-ply laminated composite material [0º/90º/0º] centrally square circular cutouts. The effect cut-out shape its size a load were obtained experimentally numerically. Compression experiment performed by ...
