A critical evaluation of the use of the Orleans Geometry Prognosis Test in the Lodi Union High School
… twenty percent of the students enrolled in the plane geometry course in the Lodi Union High School failed. Students were admitted to the course if they had attained a grade of “B” for their third quarter of first year Algebra, or if their Algebra teacher recommended that they be allowed to …

The Green's dyadic method for the analytic solution of multigroup neutron transport boundary value problems
… is based on the treatment of the steady-state, plane geometry multigroup equations for general anisotropic scattering in a homogenous medium. The problem of a system of N coupled integrodifferential equations is reduced to the evaluation of an NXN dyadic by the Green's dyadic method. Each dyadic …

On multigroup transport theory with a degenerate transfer kernel
The multigroup transport operator is studied in plane geometry assuming that the transfer kernel can be represented in a degenerate form. The eigenvalue spectrum is analyzed constructing the pertinent dispersion matrix in a block matrix form. The associated eigensolutions are obtained in terms of …

Molecular Basis of Cell Adhesion Mechanics
… The model is further extended to a sphere-on-plane geometry commonly used in measurements. Dynamic force spectroscopy using atomic force microscopy is implemented to measure one of the model parameter, the intrinsic off-rate, of the adhesive bonds between various cadherin constructs.

Analysis of Mathematical Fiction with Geometric Themes
… categories of geometric topics were analyzed: plane geometry, solid geometry, projective geometry, axiomatics, topology, and the historical foundations of geometry. Geometry textbooks aligned with these categories were discussed with regard to mathematical fiction and formal learning. Cultural …

Development of a Fast X-ray Line Detector System for Two-Phase Flow Measurement
… geometrical model has considered the measurement plane, geometry of the test-section wall and flow channel, relative position of the X-ray source and detector pixels. By assuming axisymmetry, an algorithm has been developed to convert void fraction distribution along the detector pixels to the …

Methods of Aircraft Charge Control During Flight
… is used for remote charging of a 1.9 m wingspan plane to both positive and negative polarities. By applying a voltage between -13 and +13 kV to the wire, the plane charged to +23 and -30 kV, respectively. The system demonstrates comparable results to previous modeling and wind tunnel experiments, …

Multi-scale modeling of nanosecond plasma assisted combustion
… nanosecond dielectric barrier discharges in a plane-to-plane geometry. The key kinetic pathways responsible for radicals such as O, H and OH generation from nanosecond discharges over multiple voltage pulses (ns-ms timescales) are quantified. The relative contributions of plasma thermal and …

BEHAVIOUR AND STRENGTH OF PLATE TRUNNIONS SUBJECTED TO SHEAR LOADING
… The finite element model is based on the mid-plane geometry of the specimen dimensions and only quarter models were analysed by considering appropriate symmetry conditions. Each of the specimens was modeled accordingly and the load-displacement plots of the trunnion brace results were compared …

Middle latitude forcing of a model tropical atmosphere with horizontally nonuniform basic states
… based on the primitive equations with beta-plane geometry and a latitudinally and longitudinally varying basic state is used to simulate the response of the tropics to middle latitude forcing. The equations of motion are linearized about a seasonally dependent basic state flow corresponding …

Analysis, fabrication and testing of a MEMS-based micropropulsion system
… to operate a supersonic nozzle efficiently, the geometry must be contoured to guard against flow separation and reduce the boundary layer thickness at the throat. Deep Reactive Ion Etching enables extruded flow channels of arbitrary in-plane geometry to be created at scales an order of magnitude …
