this paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. when a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...

A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

Background: Dental hygiene departments in Korean institutions of higher education regularly use radiography systems for educating students. Despite reports indicating that exposure doses from these radiation-generating devices are small, and thus, present low risks for causing physical harm or chromosomal abnormalities, the large numbers of people who participate in oral examinations involving ...

Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed rock masses but only few of them can take into account the influence of the pre-existing natur...

Sometimes, in practice, data are a function of another variable, which is called functional data. If the scalar response variable is categorical or discrete, and the covariates are functional, then a generalized functional linear model is used to analyze this type of data. In this paper, a truncated generalized functional linear model is studied and a maximum likelihood approach is used to esti...

The risk of leukemia and other radiation oriented diseases for astronauts increases with exposure to cosmic radiation. During the space missions, the blood and immune system change and the bones are affected by osteoporosis. In this research, a model, based on the human blood system, is presented for the study of the microgravity and the space radiation effects on the blood cells. This model is...
