Fine structure and the emission filling factor
Space Science Reviews, 1994There is observational evidence for an extreme fine structure in the solar transition region, much smaller than 1″ in size (Dereet al., 1987, 1988) Corresponding to this extreme fine structure there appear to be an equally complex dynamical structure.

Double Ordering and Fill-In for the LU Factorization
SIAM Journal on Matrix Analysis and Applications, 2003Summary: We present a new method, called reversed double ordering, for reordering arbitrary matrices prior to LU factorization. This reordering creates a variable-band matrix. We compare the fill-in of the LU factorization for sparse matrices with respect to reversed double ordering, column minimum degree ordering, and the reversed Cuthill--McKee ...

The Influence of Ideality Factor on Fill Factor and Efficiency of Solar Cells
Materials Science Forum, 2000The most important output characteristics of solar cells, fill factor and efficiency strongly depend on fundamental physical properties of semiconductor materials, such as mobility, lifetime of charge carriers, diffusion length, as well as on the type of transport processes in the device.

Judgment of Filled and Unfilled Durations: Intersensory Factors
Perceptual and Motor Skills, 1963Previous studies have shown a consistent intersensory difference in absolute judgments of the duration of continuous auditory and visual inputs. More visual than auditory clock time was judged equivalent to specific temporal concepts. Two experiments investigated this intersensory phenomenon further by comparing the judgments of filled auditory and ...

Multiplication factors in ethylene-filled proportional counters
Radiation Protection Dosimetry, 2008Gas multiplication factors were measured in a proportional counter filled with high-purity ethylene in the pressure range 10-40 Torr. The multiplication factors were measured as a function of the reduced electric field S(a). The results show that, within the range of the high values of reduced electric field applied in this work (2648 < or = S(a) < or =

Fill factor in organic solar cells
Solar Energy Materials and Solar Cells, 2010Abstract In this paper, we report the dependence of fill factor (FF) on different parameters in organic solar cells. FF is a more sensitive parameter compared to open-circuit voltage ( V OC ) and short-circuit current density ( J SC ), and depends on the mobility ( μ )–lifetime ( τ ) product of the bulk material, thickness of the active-polymer ...

On the fill factor of solar cells
Solid-State Electronics, 1978Abstract Calculations are presented which indicate that, for a given series resistance, the fill factor of a solar cell is principally determined by the saturation dark current, rather than the diode factor, as might be inferred from previous analyses.

Research on Fill Factor of Internal Mixers
Key Engineering Materials, 2013With the same recipe and technological conditions, experimental research on fill factor about rubber compound of all-steel radial tire was conducted in four types of X(S)M-1.7L mixers: intermeshing rotor mixer, variable intermeshing clearance mixer, shearing rotor mixer and variable shearing clearance mixer.

The Quality Factor of a Spherical Cavity Filled With a Chiral Medium
Journal of Electromagnetic Waves and Applications, 2001The expression of the quality factor of a spherical cavity filled with a homogeneous lossless chiral medium is rigorously derived for the first time. The loss on the metallic surface of the cavity is investigated. The quality factor for the lowest-order resonant mode is examined with the variation of the chirality.

Factors Affecting the Rheology and Processability of Highly Filled Suspensions
Annual Review of Chemical and Biomolecular Engineering, 2014Suspensions filled with rigid particles at volume-loading levels that approach their maximum packing fraction are widely encountered, especially in the energetics, ceramics, pharmaceutical, magnetics, composites, food, and personal care industries. Highly filled suspensions, regardless of industrial application, exhibit a number of common rheological ...
