In this paper the meshless local Petrov-Galerkin (MLPG) method is implemented to study the buckling of isotropic cylindrical shells under axial load. Displacement field equations, based on Donnell and first order shear deformation theory, are taken into consideration. The set of governing equations of motion are numerically solved by the MLPG method in which according to a semi-inverse method, ...
In this study, nonlinear axisymmetric bending analysis of Functionally Graded Carbon Nanotube Reinforced Composite (FG-CNTRC) cylindrical shell is investigated. Four distribution types of carbon nanotubes along the thickness direction of shells are considered, including a uniform and three kinds of functionally graded distributions. The material properties of FG-CNTRC shells are determined acco...
should we model error processes? What are the most promising routes to error detection and mitigation? What should be the role of knowledge-based systems? The workshop brought together 20 participants from 8 European countries and the United States in the fields of psychology, judgment, and decision making, human-computer interaction (HCI), and AI to discuss the issues based on their own resear...

برای اطمینان از عملکرد خطوط لوله دو روش عمده وجود دارد: بازرسی مخرب و بازرسی غیر مخرب. تست نشتی شاخه ای از تست های غیر مخرب است که مربوط به ورود یا خروج سیال از محیط پر فشار به محیط کم فشار می باشد. تست نشتی یک یا ترکیبی از روش های مکان یابی نشت ها، تعیین نرخ نشتی از سیستم و مانیتورینگ نشتی می باشد. یکی از مسائل مهم در خطوط انتقال نفت و گاز، نشت یابی است. از جمله تکنیک های تست غیر مخرب، استفاده...
GENERAL ENDOCRINOLOGY. By C. Donnell Turner. W. B. Saunders Co., Philadelphia, 1948. xii + 604 pp. $6.75. This book is the first edition of a text-book on general endocrinology and is aimed to meet the needs of the beginning student in experimental endocrinology. Clearly, the book accomplishes this rather modest aim and more. It is not intended to be a completely adequate handbook for the advan...
Fucosidosis is a newly recognized inborn error of metabolism involving the accumulation o f fucolipids, fucoglycoproteins, a n d fucornucopolysaccharides. T h r e e families h a v e been reported in the literature (1, 2). 1 T h e enzymic defect in fucosidosis has been established b y Van Hoof and Hers (3) as a specific, nearly complete deficiency of the enzyme ~-L-fucosidase. Thusfar, no report...
