This paper investigates how ownership changes affect the plant performance, focusing on the cotton spinning industry in early twentieth century Japan, where many plants experienced ownership changes. Through analyses of detailed plant-level data, it is revealed that, after ownership changes, plants tended to focus on low grade and low price products and, at the same time, total factor productiv...

Electrospinning technique is currently one of the most important methods for preparing nanofiber. It is important and essential to analyze the distribution of electric field in electrospinning machine. The electric field’s distribution in the typical electrospinning device was calculated and analyzed based on finite element calculation theory of electric field. The electric field is optimized b...

Although analytic solutions for the attitude motion of a rigid body are available, for several special cases, a comprehensive theory does not exist in the literature for the more complicated problems found in spacecraft dynamics. In the present paper, analytic solutions in complex form are derived for the attitude motion of a near symmetric rigid body under the influence of arbitrary, but const...

We investigate the use of runtime measurements to improve job scheduling on a parallel machine. Emphasis is on gang scheduling based strategies. With the information gathered at runtime, we deene a task classiication scheme based on fuzzy logic and Bayesian estimators. The resulting local task classiication is used to provide better service to I/O bound and interactive jobs under gang schedulin...

The spinnability of a spinning solution using DMSO as the solvent was investigated for dry-jet wet spinning of PAN precursor fiber. Among many variables responsible for spinnability, the coagulating conditions, the air gap length, the nonsolvent content in spinning solution, and the spinning temperature have been viewed as the key factors, and they were investigated in this study. It was found ...

The essence of the pneumo-mechanical spinning method lies in transformation tape into a discrete stream fibers, formation wedge-shaped ribbon from this form an open end groove chamber and yarn by torsion, which is removed wound bobbin. Yarn obtained on rotor machine differs structure ring machines, it has lower breaking load produced with higher filling twist.
