Methods to represent and exchange parts consisting of Functionally Graded Material (FGM) for Solid Freeform Fabrication (SFF) with Local Composition Control (LCC) are evaluated based on their memory requirements. Data structures for representing FGM objects as heterogeneous models are described and analyzed, including a voxel-based structure, finite-element mesh-based approach, and the extensio...
چکیده: در این مطالعه از روش ایزوژئومتریک توسعه یافته برای مدل سازی عددی ترک های ایستا جهت آنالیز گسیختگی صفحات fgmبا رویکرد ارتوتروپیک استفاده شده است. روش ایزوژئومتریک توسعه یافته از ترکیب توابع غنی ساز و روش تابع مجموعه سطوح تراز با روش آنالیز ایزوژئومتریک بوجود می آید. به علاوه روش انتگرال اندرکنش با هر سه نوع فرمول بندی مربوط به حوزه های کمکی در آنالیز گسیختگی صفحات fgm ) یعنی فرمول بندی ع...
BACKGROUND Females' genital mutilation (FGM) is one of the harmful traditional practices affecting the health of women and children. It has a long-term physiological, sexual and psychological effect on women. It remains still a serious problem for large proportion of women in most sub-Saharan Africa countries including Ethiopia. METHODS A community based cross sectional study design which is ...
Functionally Graded Materials (FGM) parts are heterogeneous objects with material composition and microstructure that change gradually into the parts. The distinctive feature of FGM structure gives the possibility of selecting the distribution of properties to achieve the desired functions. Today, multimaterial parts manufactured with additive manufacturing processes are not functional. To move...
An important task in exploring and analyzing real-world data sets is to detect unusual and interesting phenomena. In this paper, we study the group anomaly detection problem. Unlike traditional anomaly detection research that focuses on data points, our goal is to discover anomalous aggregated behaviors of groups of points. For this purpose, we propose the Flexible Genre Model (FGM). FGM is des...
In this paper, we provide a unified and self-consistent treatment of a functionally graded material (FGM) microbeam with varying thermal conductivity subjected to non-uniform or uniform temperature field. Specifically, it is our objective to determine the effect of the microscopic size of the beam, the electrostatic gap, the temperature field and material property on the pull-in voltage of the ...
در این مقاله به بررسی باز توزیع تنش ها و تغییرشکل ها در طی زمان در مخازن کروی جدار ضخیم fgm تحت فشار داخلی و توزیع دمای شعاعی پرداخته می شود. خواص مکانیکی و حرارتی ماده به غیر از ضریب پواسون به صورت تابع توانی برحسب شعاع فرض شده اند. در رژیم خزشی، کرنش های کل در هر زمان به صورت مجموع کرنش های مکانیکی، خزشی و حرارتی هستند که هریک توابعی از شرایط بارگذاری و زمان می باشند. با استفاده از روابط تنش-...
The Steady state creep behaviour of a functionally graded cylinder made of isotropic composite containing varying distribution of silicon carbide particles has been investigated by a mathematical model. The creep behaviour of the FGM is described by a Norton's Power law. The effect of varying distribution of SiCP particles of creep stresses and creep rates in the FGM cylinder has been anal...
Background: Female genital mutilation (FGM) occurs mainly in Africa, parts of the Arabian Peninsula and parts of Asia. It is commonly associated with acute complications as well as diverse late/delayed complications. One of the most common of these late complications is progressively enlarging painless cysts of the vulva. Case Report: An 8-year-old girl from Eritrea presented to our paediatric ...
OBJECTIVE To estimate the number of women with female genital mutilation (FGM) living in Belgium, the number of girls at risk, and the target population of medical and social services (MSSs) concerned. METHODS Data about prevalence of FGM from the most recently published Demographic and Health Surveys and Multiple Indicator Cluster Surveys were applied to females living in Belgium who migrate...
