Accurate rainfall data are essential for environmental applications in the actual assessment of geographical distribution rainfall. Interpolation methods usually applied to monitor spatial data. There many interpolation methods, but none them can achieve all cases best results. In this study, three different were investigated with regard their suitability producing a distribution. Rainfall from...

In recent years, there has been an increasing demand on efficient algorithms for large scale change point detection problems. To this end, we propose seeded binary segmentation, approach relying a deterministic construction of background intervals, called in which single points are searched. The final selection based the candidates from intervals can be done various ways, adapted to problem at ...

mouse embryo. In original 2D ISH sections (a), it is difficult to comprehend the distributions of Lhx8 (blue) and Shh (brown) genes relative to each other and to brain structures. After mapping, coregistered Lhx8 (orange) and Shh (green) expression data are overlaid on the iDW image (b), and inspected in 3D with brain structures e.g. ventricles (blue) to appreciate the spatial expression patter...

Background. Although heart-to-mediastinum (H/M) ratio in a planner image has been used for practical quantification for I-metaiodobenzylguanidine (MIBG) imaging, standardization of the parameter is not yet established. We hypothesized that the value of H/M can be standardized to the various types of camera-collimator combinations. Methods and Results. Standard phantoms consisting of the heart, ...

This study correlated lung cancer (LC) mortality with statistical data obtained from government public databases. In order to asses a relationship between LC deaths and radon accumulation in dwellings, indoor radon concentrations were measured with passive detectors randomly distributed in Chihuahua City. Kriging (K) and Inverse-Distance Weighting (IDW) spatial interpolations were carried out. ...

The main goal of texture analysis is to extract useful textural information from an image. The use of Bayesian methods is an approach, which seeks to provide a unified framework in modeling within many different image processes. In this work, spatial behavior of the auto-logistic model in a rectangular lattice would be investigated, concentrating the first-order neighborhood structures. A simpl...

The lower Athabasca River watershed is one of the most important regions for Alberta and elsewhere due to fact that it counts for the third largest oil reserve in the world. In order to support the oil and gas extraction, Athabasca River provides most of the required water supply. Thus, it is critical to understand the characteristics of the river and its watershed in order to develop sustainab...
