In this paper, a neural network based uniformity controller is developed for the linear chemical–mechanical planarization (CMP) process. The control law utilizes the metrology measurements of the wafer uniformity profile and tunes the pressures of different air-bearing zones on Lam linear CMP polishers. A feedforward neural network is used to self-learn the CMP process model and a direct invers...
performance appraisal systems are affected by organizational social context. social context consists of tow factors, distal variables, and, proximal variables. distal factors include but are not limited to organizational culture, organizational structure, and, values. proximal variable categorize as both process factors and structural factors. in this paper the process factors were examined. th...
BACKGROUND Previous studies have reported worse outcomes in children with nondilated cardiomyopathy (CMP) listed for heart transplant compared with children with dilated CMP. We sought to compare wait-list and posttransplant outcomes in these groups in the current era. METHODS AND RESULTS We analyzed all children <18 years of age with a diagnosis of CMP listed for heart transplant in the Unit...
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
the present research was an attempt to see how quranic lexical collocations were translated into english by two professional translators namely, abdullah yusuf(2005), and muhammad s. shakir(2012). the study attempted qualitatively to shed light on how translators dealt with quranic lexical collocations when transferring them to the target language based on the newmark(1988) model , and quantit...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
INTRODUCTION Interactions of the ceria particles with polyurethane surfaces are of great interest for polishing processes used in modern semiconductor industry. Specifically, ceria abrasive nanoparticles and polyurethane polishing pads are now broadly used in the process called Chemical-Mechanical Planarization/Polishing (CMP) [1,2,3]. To optimize the process of CMP, various chemicals, abrasive...
Optimization of Paclitaxel Containing pH-Sensitive Liposomes By 3 Factor, 3 Level Box-Behnken Design
The aim of this study was to investigate the combined influence of 3 independent variables in the preparation of paclitaxel containing pH-sensitive liposomes. A 3 factor, 3 levels Box-Behnken design was used to derive a second order polynomial equation and construct contour plots to predict responses. The independent variables selected were molar ratio phosphatidylcholine:diolylphosphatidyletha...
*Correspondence: [email protected] 1Department of Mathematics and Statistics, Georgetown University, 306 St. Mary’s Hall, Washington, DC, 20057, USA Full list of author information is available at the end of the article Abstract The Poisson, geometric and Bernoulli distributions are special cases of a flexible count distribution, namely the Conway-Maxwell-Poisson (CMP) distribution – a two-pa...
