BACKGROUND Controversy exists in predicting costly hospitalization in patients with chronic kidney disease and co-morbid conditions. We therefore tested associations between serum chemistry values and the occurrence of in-patient hospital costs over a thirteen month study period. Secondarily, we derived a linear combination of variables to estimate probability of such occurrences in any patient...

The weighted linear combination (WLC) technique is a decision rule for deriving composite maps using GIS. It is one of the most often used decision models in GIS. The method, however, is frequently applied without full understanding of the assumptions underling this approach. In many case studies, the WLC model has been applied incorrectly and with dubious results because analysts (decision mak...

the county of khorram-abad enjoys a high potential for ecotourism because of its mountains, forests, natural mineral springs, natural waterfalls and diversity in folks and cultures. but, un-planned and uncontrolled ecotourism can have negative effects on environment, economy, culture and even the security of eco-tourists. the main purpose of this study is to present a fuzzy multi-criteria decis...

this study recommends a gis-based (geographic information systems) and multi-criteria evaluation for site selection of gas power plant in natanz city of iran. the multi-criteria decision framework integrates legal requirements and physical constraints related to environmental and economic concerns. it also builds a hierarchy model for gas power plant suitability. the methodologies used for site...

The Kaczmarz method for solving a linear system $Ax = b$ interprets such as collection of equations $\left \langle a_i, x\right \rangle b_i$, where $a_i$ is the $i$-th row $A$. It then picks an equation and corrects $x_{k+1} x_k + \lambda a_i$ $\lambda$ chosen so that satisfied. Convergence rates are difficult to establish. Strohmer & Vershynin established if order randomly (with likelihood pro...

recent literature attaches high importance to scenic evaluation of natural landscapes. scenic beauty evaluation techniques often use parameters derived from photographs or collected in situ data via field assessment and questionnaires. such techniques are relatively costly and time consuming. park managers and recreational planners require spatial tools and techniques that are fast, flexible an...

Wind power prediction is one of the most significant technologies to promote the capability of the whole power system that takes in wind electricity. A combined model for wind power forecasting is presented to decrease the influence of reconstructed parameters by chaotic time series analysis and the neural networks (NNs) in this work. The combined model respectively makes use of linear weighted...
