Fraction-Free Methods for Determinants
… using a method that does not introduce fractions. Fraction-Free Triangularization, Bareiss’ Algorithm (based on Sylvester’s Identity) and Dodgson’s Method (based on Jacobi’s Theorem) are three such methods. However, both Bareiss’ Algorithm and Dodgson’s Method encounter division by zero …

Undergraduate Developmental Mathematics Students' Fraction Understandings
Difficulties with fractions are well-documented for undergraduate developmental mathematics students. Thus, it may not be surprising that fractions act as a gate-keeping topic for college-level mathematics. However, research on the way(s) that undergraduate developmental mathematics students …

Fraction Instruction That Fosters Multiplicative Reasoning
… development of a model for partitive division of fractions, which model can be a valuable tool in understanding and determining unit rates. In partitive division, the task is to find the amount of the first quantity in one unit of the second quantity. For example, in the problems $6 ÷ 2 …

Generalizations of Certain Results on Continued Fraction
… of the Rogers-Ramanujan continued fraction. The Rogers-Ramanujan continued fraction arises from a three-term q-difference equation. We consider (m + 1)-term q-difference equations and also a generalization of the continued fraction algorithm called a G-continued fraction. We obtain …

Forensic Soil Analysis: Characterization of the Sand Fraction
… A Gilson sonic sieve shaker was used to separate fractions of soil to determine particle size, and a JEOL scanning electron microscope with a Kevex EDS detector was used to determine elemental composition. These techniques coupled with percent total carbon analysis (determined with a LECO …

Fraction Models That Promote Understanding For Elementary Students
… the use of the set, area, and linear models of fraction representation to enhance elementary students' conceptual understanding of fractions. Students' preferences regarding the set, area, and linear models of fractions during independent work was also investigated. This study took place in a …

Analysis of the diurnal behavior of Evaporative Fraction
… this thesis, the diurnal behavior of Evaporative Fraction (EF) was examined. EF was shown to exhibit a typical concave-up shape, with a minimum usually reached in the middle of the day. The influence of the vegetation cover and the soil moisture conditions on EF diurnal shape was also …

Measurements of the absolute branching fraction of Λc+ → pK-π+ and the relative branching fraction of Bu+ → p π+ π+ Σc(2520)--.
… of the absolute Λc+ → pK-π+ branching fraction was performed, in a model independent way and for the first time in a hadronic environment, on data recorded by the LHCb experiment during the years 2011 and 2012, corresponding to an integrated luminosity of 3fb-1 . The branching fraction …

The pathophysiology of heart failure with preserved ejection fraction
Our studies demonstrate that patients with HfpEF have impaired myocardial energetics as indicated by the diminished in vivo myocardial PCr/ATP ratio. Data acquired during semi-supine cycling exercise indicates that patients with HfpEF had a dynamic impairment of LV active relaxation. In addition, …

The void fraction in headers of microchannel heat exchangers
… to other traditional heat exchangers. The void fraction in the headers affects the thermal performance, refrigerant charge, and total pressure drop of MCHEs. However, due to the complex geometry of headers, measurements of void fraction in headers are challenging. A model that predicts the local …

Model-based myelin water fraction mapping: analyses and improvement
… thesis, the problem of model-based myelin water fraction (MWF) mapping is addressed. We first focus on three of the most widely used signal models for T2*-myelin water imaging (MWI), i.e., the NNLS-multi-exponential model, the magnitude-3-exponential model, and the complex-3-exponential model, …

An ERP investigation of symbolic and nonsymbolic fraction processing
Fractions, though important, pose significant difficulties for children and adults. It has been suggested that this difficulty may stem from a lack of an underlying cognitive system that allows us direct, intuitive access to fraction magnitude. However, there is mounting evidence that processing …
