Fault diagnosis depends largely on feature analysis of vibration signals. However, feature extraction for fault diagnosis is difficult because the vibration signals often contain a strong noise component. Noises stronger than the actual fault signal may interfere with diagnosis and ultimately cause misdiagnosis. In order to extract the feature from a fault signal highly contaminated by the nois...

conclusions an extremely rare condition, a spontaneous intracranial pneumocephalus with skull base defect origin could be considered as a possible diagnosis in patients with sudden and severe headache. we can safely conclude that medical treatment and close follow-up is an effective mode of therapy in this patient. introduction spontaneous pneumocephalus without any pathological condition is ve...

Astigmatism’s defect has not yet been formulated in Physics and medical physics books theoretically. In this paper, we are trying to formulate the astigmatism’s defect. The results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...

conclusions children with chd are at risk of severe complications with the involvement of other organs. long-term febrile illness should be taken seriously in these children. they need hospitalization and careful evaluation. case presentation a 6-year-old girl with a ventricular septal defect (vsd) was presented. echocardiography revealed large vegetation in the right ventricular outflow tract ...

Sheath currents in high voltage cable circuits have proven to be one of the most convenient indicators for assessing health. The sheath are regularly distributed with fluctuation a certain range under normal conditions, while principle distribution characteristics is still unclear when cross-bonded grounding system circuit abnormal. This paper classifies common defects into three types topologi...

in all legal systems, it’s essential to know the nature of fault due to the absolute responsibility of a salesman or producer, on the one hand, and the possibility of receiving compensation on the other hand. in islamic law, this absolute responsibility is interpreted as ḍamān (indemnification); therefore, this ḍamān that is our subject of discussion in option of defect, is taken into considera...

Gerbode defect is a rare shunt between the left ventricule and right atrium. The etiology typically congenital. infravalvular type most common. congenital defects are believed to close by forming an aneurysmal pouch through incorporating adjacent tricuspid valve tissue. Endocarditis responsible for this re-opening defect. Diagnosis based on transesophageal echocardiography. Surgical closure dem...

Prenatal diagnosis with application of the Amniotic fluid (Amniocentesis: AC) and chorionic villi sampling {CVS) is a general aspect of application in Human Genetics which facilitate the diagnosis of different Genetic defects, enclosing chromosomal abnormalities and Genosomopathies. Diagnosis of Genetic defects for AC and CVS is between 16-20th and 8-12th weeks of gestation respectively. Allica...

Twenty-three consecutive patients with clinical (auscultatory and electrocardiographic) signs of uncomplicated atrial septal defect of secundum or sinus venosus type were examined by chest x-ray, phonocardiography, and echocardiography, before right heart catheterisation. Seventeen (74%) had atrial septal defect, two patients (9%) had insignificant pulmonary stenosis, and four subjects (17%) we...
