در این تحقیق از بهینه‌سازی تابع هدف طراحی آزمایشی تاگوچی برای یافتن شرایط بهینه فرایند قالبگیری تزریق به‌کمک آب برای دو پلیمر ABS و PP استفاده شده است. به منظور قالبگیری تزریقی نمونه‌‌ها، قالب لوله‌ای دو سر با حفره مواد اضافه و نازل تزریق آب طراحی و ساخته شد. با توجه به اینکه توابع هدف مختلفی در این فرایند مدنظر است، لذا از روش بهینه‌سازی تابع هدف با معیارهای چندگانه کلی (OEC)استفاده شد. نوع مش...

The implementation of the Organisation for Economic Co-operation and Development (OEC D) principles of good laboratory practice (GLP) on an international level is well advanced. However, the OEC D GLP guidelines as well as the corresponding national GLP regulations leave room for interpretation. As a consequence, working in parallel in GLP environments in several countries represents a challeng...

Orthogonal Eigenstructure Control (OEC) is a novel control method that can be used for active vibration cancellation. OEC is an output feedback control method applicable to multiple-input, multiple-output linear systems. In this paper, application of OEC for active vibration cancellation in a plate is presented. A steel plate clamped at four edges is used as a test plate and piezoelectric actua...

OBJECT The results of olfactory ensheathing cell (OEC) transplantation have raised great expectations as a potential treatment for spinal cord injury (SCI). Its capacity to promote functional neural repair, however, remains unclear. The authors studied axonal growth and locomotor recovery after C-7 contusion injury and OEC transplantation in adult rats. METHODS Twenty-four male Wistar rats un...

The goal of this work is to construct, for a smooth variety X over a perfect field k of finite characteristic, an overconvergent de Rham-Witt complex W ΩX/k as a suitable subcomplex of the de RhamWitt complex of Deligne-Illusie. This complex, which is functorial in X, is a complex of étale sheaves and a differential graded algebra over the ring W (OX) of overconvergent Witt-vectors. If X is aff...

The purpose of this investigation was to ascertain whether outcome expectancies and criminal thinking would change in offenders participating in a psychoeducational group and whether significant cross-lag (over time) correlations could be identified between outcome expectancies and criminal thinking. A sample of 121 US federal inmates completed the Psychological Inventory of Criminal Thinking S...

Résumé. — On a montré dans un précédent travail que le complexe bar n-itéré usuel des algèbres commutatives s’étend aux En-algèbres et détermine l’homologie naturelle associée à cette catégorie d’algèbres. On montre dans cet article que le complexe bar n-itéré d’une En-algèbre forme un diagramme sur un remplacement cofibrant de la catégorie des arbres élagués à n niveaux – une variante de la ca...
