Prognostics is a method that permits the assessment of product reliability under its actual application conditions. While there are various methods to perform prognostics, including physics of failure and data-driven methods, these methods have some key disadvantages. This paper presents a fusion prognostics approach, which combines or “fuses together” the physicsof-failure and data-driven meth...

Determining battery lifetimes is beset with difficulties. Performance data are not generally available and costly to generate since large numbers of batteries must be tested to destruction. Furthermore, the required test period to verify the predictions is often greater than commercial decision lead time. While the reliability predictions in the following section are very useful, they are desig...

Congenital Hepatic Fibrosis (CHF) is a rare disease that affects both the liver and kidneys.  Congenital hepatic fibrosis (CHF) is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. Affected individuals also have impaired renal function, usually caused, in children and teenagers, by an...

AbstractBackgroundline of treatment for management of hydrocephalus despite available new techniques andsystems of shunting. Associated complications should be recognized and managed properly,but the most recognized complications are shunt obstruction which its prevalencethrough surgical approach is discussed here. Two approaches (frontal and parietal) are usedto insert ventriculoperitoneal shu...

The most common cause of gastric outlet obstruction in neonates and infants is hypertrophic pyloric stenosis. Pyloric web as a cause of gastric outlet obstruction is relatively rare in children and presents with non bilious vomiting, abdominal pain and failure to thrive. The onset of symptoms is usually late with nonspecific symptoms like vomiting and failure to thrive that seems to be due to n...

The subject of this thesis forms part of a research program dealing with fractured rock masses being undertaken by the "Centre de Géologie de l'Ingénieur (CGI)" from the "Ecole Nationale Supérieure des Mines de Paris (ENSMP)" and the "Ecole Nationale des Ponts et Chaussées (ENPC)". In fractured rock masses, it is very difficult to undertake engineering works without analysing, beforehand, the f...

diabetes mellitus is one of the common diseases leading to dialysis. in a cohort study, diabetic dialysis patients were compared with non-diabetic dialysis patients for one year about age, sex, cause and times of admission and rate of mortality. the study was done on 101 patients. at the end of the study, 88 patients remained. results were interprected by t-test and chi-square statistical analy...
