background: increasing prevalence of obesity is a major health concern. lifestyle behaviors and diet play an important role in developing childhood obesity. the aim of this study was to determine the association between major dietary patterns and overweight/obesity in a group of iranian school‑aged children. methods: this cross‑sectional study was conducted in isfahan, iran with 637 elementary ...

This paper describes a research framework and methodology for explorative analysis and quantitative evaluation of commercial, business-to-consumer Web information systems (WIS). The suggested approach is suitable for both longitudinal studies and industry-specific comparisons. As such, it may provide the basis for constructing reference models, for optimizing the allocation of marketing resourc...

The analysis of time-dependent data is an important problem in many application domains, and interactive visualization of time-series data can help in understanding patterns in large time series data. Many effective approaches already exist for visual analysis of univariate time series supporting tasks such as assessment of data quality, detection of outliers, or identification of periodically ...

Neural recordings are non-stationary time series, i.e. their properties typically change over time. Identifying specific changes, e.g., those induced by a learning task, can shed light on the underlying neural processes. However, such changes of interest are often masked by strong unrelated changes, which can be of physiological origin or due to measurement artifacts. We propose a novel algorit...

Hierarchies of plane graphs, called graph pyramids, can be used for collecting, storing, and analyzing geographical information based on images or other input data. The visualization of graph pyramids facilitates studies about their structure, such as their vertex distribution or height in relation of a specific input image. Thus, a researcher can debug contraction processes and ask for statist...

Pharmacogenetics aims to identify genetic variation to predict drug response or to establish an individual optimal dose. Classically, explorative pharmacogenetic studies are performed concerning a limited number of SNPs in genes encoding enzymes involved in the drug's metabolic route. Alternatively, potential markers across the genome are elucidated by the performance of the hypothesis-free gen...

This paper discusses the effective length factor of columns in Khorjini frames. In order to find this factor, a proper approximated method is proposed. In addition, accurate analysis is performed and the results are compared with those from the proposed technique. The comparison demonstrates the accuracy of presented FORMULATIONS. The proposed method is similar to Julian and Lawrence's, which i...
