Associative Hierarchical Random Fields
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014 This paper makes two contributions: the first is the proposal of a new model-The associative hierarchical random field (AHRF), and a novel algorithm for its optimization; the second is the application of this model to the problem of semantic segmentation.

Application of the Coupled Markov Chain in Soil Liquefaction Potential Evaluation
Buildings, 2022 The evaluation of localized soil-liquefaction potential is based primarily on the individual evaluation of the liquefaction potential in each borehole, followed by calculating the liquefaction-potential index between boreholes through Kriging ...

Reliability Analysis of Layered Soil Slopes Considering Different Spatial Autocorrelation Structures
Applied Sciences, 2020 It is widely recognized that different geological formations often vary differently in space. Therefore, soil properties from different layers should be modeled by different autocorrelation functions (ACFs) to reflect such soil heterogeneity.

Crossover from random-exchange to random-field critical behavior in Ising models [PDF]
, 2003 We compute the crossover exponent $\phi$ describing the crossover from the random-exchange to the random-field critical behavior in Ising systems. For this purpose, we consider the field-theoretical approach based on the replica method, and perform a six-

Many-body localization edge in the random-field Heisenberg chain [PDF]
, 2014 The authors study the phenomena of many-body localization in a random field Heisenberg chain. In this paper the authors use a shift-inverse exact diagonalization approach that allows them to study the mid-spectrum spectral properties of the model for ...

Online Phase Measurement Profilometry for a Fast-Moving Object
Applied Sciences, 2021 When the measured object is fast moving online, the captured deformed pattern may appear as motion blur, and some phase information will be lost. Therefore, the frame rate has to be improved by adjusting the image acquisition mode of the camera to adapt ...

Applied Sciences, 2021 Artificial ground freezing (AGF) technology has been commonly applied in tunnel construction. Its primary goal is to create a frozen wall around the tunnel profile as a hydraulic barrier and temporary support, but it is inevitably affected by two natural

REVIEW OF RECENT RESULTS ON EXCURSION SET MODELS
Image Analysis and Stereology, 2011 Many images consist of two or more "phases", where a phase is a collection of homogeneous zones. For example, the phases may represent the presence of different sulphides in an ore sample.

The Sequential Generation of Gaussian Random Fields for Applications in the Geospatial Sciences
ISPRS International Journal of Geo-Information, 2014 This paper presents practical methods for the sequential generation or simulation of a Gaussian two-dimensional random field. The specific realizations typically correspond to geospatial errors or perturbations over a horizontal plane or grid. The errors
