intracranial hemorrhage is one of the major causes of neonatal mortality and morbidity. it is the most severe cranial problem in that period. those who survive would be affected by hydrocephalus, encephalomalacia, and finally brain atrophy. with accurate knowledge of risk factors, hemorrhage may be diagnosed earlier and the complications managed earlier. this study was performed in neonatal int...

for differential equations with r parameters, 2r + 1 experiments are enough for identification Abstract Given a set of differential equations whose description involves unknown parameters, such as reaction constants in chemical kinetics, and supposing that one may at any time measure the values of some of the variables and possibly apply external inputs to help excite the system, how many exper...

Imagine a global community of people who—as matter daily routine—observe wildlife, smell the air, discuss weather and touch world around them. As sensors, have evolved ability to assess environmental change one might easily conceive an army such ‘citizen scientists’ ready willing advance knowledge. Of course, it is not that straightforward. Although volunteers supported science for decades, con...

Slope stability is calculated using several methods. All these methods produce estimated results based on inaccurate assumptions, and their were particularly acceptable. Furthermore, rely supposing segmenting the surface of failure as well performing complex calculations. This paper introduces “Dimensional Analysis Technique” a new approach for dealing with earthen slopes. Four dimensionless gr...

Given a set of differential equations whose description involves unknown parameters, such as reaction constants in chemical kinetics, and supposing that one may at any time measure the values of some of the variables and possibly choose external inputs to help excite the system, how many experiments are sufficient in order to obtain all the information that is potentially available about the pa...
