This paper presents new valuable field data and a comprehensive approach to the determination of the rock mass classification and tunnel support systems for tunnels in unconsolidated sedimentary rocks as a special soil condition. The main objective of this study is to investigate and present the characteristics of the unconsolidated sedimentary rock by using the point load tests and slake durab...

In this paper we present a technique to detect masses from digital mammograms using Artificial Neural Network (ANN), which performs malignant-normal classification on region of interest (ROI) that contains mass. The major mammographic characteristics for mass classification are Intensity, Shape and Texture. ANN exploits all such type of important factor to classify the mass into malignant or no...

asthma is now recognized as a common cause of disability of great economic cost and preventable deaths. in this study we aimed to test our hypothesis based on the relationship between body mass index and bronchial asthma .among the patients with acute asthma admitted to the emergency ward and pulmonology clinic, we sought to determine the prevalence of obesity, as well as the effect of body mas...
