Statistical distribution of times to crack initiation in service using C-130 inspection data
… and initial flaw sizes were derived. Several statistical distributions were fitted to the times to crack initiation and to initial flaw sizes in order to describe analytically their expected behavior at each location.

The role of statistical distributions in vulnerability to poverty analysis
… is compounded by the need to select appropriate statistical distribution for weather anomaly measures and household characteristics. We address these challenges by analyzing household consumption data from the Living Standards Measurement Study survey in Niger and systematically evaluating how …

Preventive maintenance scheduling based on failure data in a medical device manufacturing facility
… to track defects over the mold cavities . Statistical distribution tests on the failure times of the molds were carried out and found that the failure times for the molds differ. Mold failure times follow the log normal or Weibull distribution. Parameter estimates obtained from probability …

Effect of scale and spatial variability on surface foundation on sand
… function is used to characterize the statistical distribution of void ratio. Monte Carlo simulations are performed to establish impact of sand density variability and correlation length ratios on foundation bearing resistance. The stochastic predictions of N[subscript gamma] show that …

Statistical response predictions in complex systems with dissipation
… are examined for the purpose of improving statistical response predictions such as those formulated in statistical energy analysis and statistical room acoustics. Both the statistical distribution of modal decay rates and the effect of dissipation on the intermodal correlations of natural …

Subdivisions and correlations of the Tully Formation (Upper Devonian) in New York State and Pennsylvania on the basis of a statistical and stratigraphical analysis of selected conodonts.
… P. varca, P. iuvenis and Icriodus. The statistical distribution of the four taxa is independent of the local lithology, but follows stratigraphical units. The studied conodont faunal succession of the Tully Formation includes a conodont zone not yet described from Europe. This new zone …

A measure of the natural potential of land for supporting deer populations
… forage production are made by use of a flexible statistical distribution model known as a \.Jeibull distribution. Indices of the potential sightable and harvestable deer production are calculated in standard deer units at 5-year intervals over a 50-year planning horizon.

Statistical modeling of heterogeneous data
… in this digital information age. From the statistical point of view heterogeneous data is composed of dissimilar components, where objects in each component are homogeneous themselves. One such example from the real world is the stock return data, where stocks in the same industry segments …

Diffusion in an absorbing porous medium : from microscopic geometry to macroscopic transport
… the solid fraction to the two-thirds power. The statistical distribution of reaction rates in these models is found to be inversely related to the reaction rate. A quasi-static Monte-Carlo model is also investigated. The more complex problem of microbial extracellular enzyme distributions in …

Decision-making under uncertainty using a new chance constrained programming technique: A groundwater reclamation application
A new distribution free chance constrained programming technique is developed and applied to the design of hydraulic gradient control methods for containment and removal of contamination in an aquifer. The spatial distribution of parameters such as transmissivity in a heterogeneous domain make the …

Rollback-able Random Number Generators For The Synchronous Parallel Environment For Emulation And Discrete-event Simulation (spe
… are represented in the system by using various statistical models, like random number generators. These random number generators can be used to represent a various number of factors, such as length of the queue. However, simulations have grown in size and are sometimes required to run on …

The oblique effect as a measure of digital media overuse
… 0° and 90° contours over oblique reflects the statistical distribution of contours in the visual environment such that there is more neural representation in the visual cortex (area V1) for horizontal and vertical (anisotropic) contours than otherwise ((Hubel & Wisel, 1962). The oblique effect …

Structural Damage Detection and Assessment From Spatially Sparse and Noise -Polluted Modal Response
… level of the damage localization process. The statistical distribution of the element parameters of the damaged and the associated baseline structure is used to assess the severity of damage at the potential damage sites. The proposed damage detection and assessment procedure is tested with a …

The Vulcanization Transition and the Amorphous Solid State It Yields: A Statistical Mechanical Perspective
… and the scaling function that describes the statistical distribution of localization lengths. Our investigation of the vulcanization transition beyond the mean-field level, via both a perturbative renormalization group approach and a diagrammatic analysis of the two- and three-point vertex …

Communication in a Poisson field of interferers
… positions. Under this scenario, we determine the statistical distribution of the cumulative interference at the output of a linear receiver, located anywhere in the two-dimensional plane. We characterize the error probability and capacity of the link, when subject to both network interference and …

Variational Autoencoders for Discovering Influential Latent Factors
… unseen data instances by means of modeling the statistical distribution of data. Generative modeling falls under the broad area of representation learning, which aims to discover representations required for detecting features, classification, and other ways of understanding data. In this vein, …

Memory and locality in natural language
… other, both in their interpretation and in their statistical distribution, should be close to each other in linear order. The informationtheoretic approach to natural language motivates a study of quantitative syntax in Chapter 2, focusing on word order flexibility. In Chapter 3, I show …
