Estimation of polynomial roots by continued fractions
One of the ways to describe dynamical characteristics of the system is the s-transfer function, which belongs to the class of the so-called external descriptions and from the mathematical point of view it represents a rational function. Decomposition into the partial fractions (sum of exponential functions in the time domain) is based on the knowledge of the roots of the polynomial defined by t...
متن کاملEstimation of Photon Specific Absorbed Fractions in Digimouse Voxel Phantom using Monte Carlo Simulation Code FLUKA
Background: Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs.Objective: SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV...
متن کاملEstimation of uranium GI absorption fractions for children and adults.
Uranium is ubiquitously found in drinking water and food. The gastrointestinal tract absorption fraction (f(1)) is an important parameter in risk assessment of uranium burdens from ingestion. Although absorption of uranium from ingestion has been studied extensively in the past, human data concerning children and adults are still limited. In a previous study based on measurements of uranium con...
متن کاملMagnitudes of fractions 1 RUNNING HEAD: MAGNITUDES OF FRACTIONS Representations of the Magnitudes of Fractions
We tested whether adults can use integrated, analog, magnitude representations to compare the values of fractions. The only previous study on this question concluded that even college students cannot form such representations and instead compare fraction magnitudes by representing numerators and denominators as separate whole numbers. However, atypical characteristics of the presented fractions...
