Equating discriminability of subjective contours across the visual field requires two scaling factors
… often be equated across eccentricities by proper scaling. The scaling or inverse magnification function (EMF), describes the ratio of peripheral to foveal stimulus size required to equate performance. Tasks and visual brain regions have different IMFs. It is argued in this thesis that IMFs may …

Spatial Variation of Magnitude Scaling Factors During the 2010 Darfield and 2011 Christchurch, New Zealand, Earthquakes
Magnitude Scaling Factors (MSF) account for the durational effects of strong ground shaking on the inducement of liquefaction within the simplified liquefaction evaluation procedure which is the most commonly used approach for assessing liquefaction potential worldwide. Within the context of the …

An Experimental Investigation of the Injection Process in a Direct-Injected Natural Gas Engine Using PLIF and CARS
A set of scaling factors derived from the conservation equations effectively collapsed fuel jet penetration measurements under both motoring and stationary piston conditions. The scaling factors are based on the pseudo diameter of the jet, which is the diameter of an equivalent sonic jet expanded …

An Evaluation of Scaling Methods for Earthquake Response Spectra
… range of frequencies. In this study, alternative scaling factors are evaluated with the purpose of reducing the dispersion encountered in normalized spectral ordinates. The scaling factors fall into two major groups, one based on ground motion data, and the other, directly on response quantities. …

Adaptive Rollover Control Algorithm Based on an Off-Road Tire Model
… it to off-road surfaces through the use of scaling factors. The scaling factors are multipliers in the Magic Formula that describe how different aspects of the force and moment curves scale when the tire is driven on different surfaces. Scaling factors for dirt and gravel driving surfaces …

Study of the Radionuclide Composition of Radioactive Waste Streams in the Nuclear Power Plant /
… results, and recommendations on application of scaling factors for characterization of different radioactive waste streams are given. Dependence of difficult-to-measure radionuclide scaling factors on the radioactive waste stream was analyzed.

The Persistence of Acid Mine Drainage at an East Texas Coal Mine
… to the leachate humidity cell data to determine scaling factors that could be applied to the laboratory-based humidity cell experiment. These scaling factors coupled with regression analysis were then used to extrapolate the length of time it would take pyrite to fully oxidize at the mine site …

Analytical Evaluation of the Accuracy of Roller Rig Data for Studying Creepage in Rail Vehicles
… and Vermeulen are used to establish correction factors, scaling factors, and transformation factors that allow us to relate the results from a scaled rig to those of a tangent track. �Correction factors, which are defined as the ratios of a given quantity (such as creep coefficient) between a …

Scaling air quality effects from alternative jet fuel in aircraft and ground support equipment
… to ambient particulate matter concentrations. Scaling factors were developed for airport criteria pollutant emissions to model alternative jet fuels in aircraft and ground support equipment. These linear scaling factors were based on currently published studies comparing standard diesel and jet …

Studies of some issues in solving surface integral equations and the equivalence principle algorithm
… and analyses of these operators with proper scaling factors are included to avoid the inaccuracy due to iterative solvers. Later we provide pertinent results for all of them for verification and comparison.

Wedged Vortex Generator Applications for Marine Vessels
… carrier using appropriate geometric and dynamic scaling factors. Total resistance was partitioned using Holtrop-Mennen approximations, allowing the drag reduction to be realistically applied to operational conditions on a trans-Pacific route. Material and installation cost estimates were also …

QT variability calculation using a template matching algorithm and power spectral analysis
… error function, which is minimized to find the scaling factor for that beat. These scaling factors are compiled into an array, and an interpolated signal is generated of QT interval times. Using Lab VIEW and MATLAB, the algorithm was put into place, and frequency spectral analysis conducted on …

Adaptive power control as a fade countermeasure on satellite links
… not an appropriate parameter for ULPC. Real time scaling of attenuation from the downlink to the uplink shows more promise for ULPC. Differences in drop size distributions during a rain storm will result is different scaling factors. If the downlink attenuation is limited to 6 dB at 20 GHz, real …

Bicycle and Pedestrian Traffic Monitoring and AADT Estimation in a Small Rural College Town
… of non-motorized traffic and (2) develop scaling factors (analogous to those used in motor vehicle count programs) derived from the continuous reference sites to estimate long-term averages (i.e., AADT) for short-duration count sites. I collected ~40,000 hours of bicycle and pedestrian …

Method of reliability-based calibration of seismic structural design parameters
… behavior of the structure. Response scaling factors based on extensive regression analyses of structures of up to 12 stories under historical earthquakes are then applied to the responses calculated using the ENS in order to obtain responses comparable to the original structure. …

Bridging the Gap between Deterministic and Stochastic Modeling with Automatic Scaling and Conversion
… be scaled before a complete conversion, and the scaling factors are typically not given in the deterministic model. Several functionalities helping model scaling and converting are introduced and implemented in the JigCell modeling environment. Our tool makes it easier for the modeler to include …
