introduction: nutrition plays an important role in the protection and promotion of health. to plan and implement programs aiming at improving community nutritional status, a knowledge of the existing situation is essential. the aim of this cross-sectional study was to determine food and nutrient intakes of the inhabitants in tehran university of medical sciences population laboratory. methods: ...

The pyramid method for content evaluation of automated summarizers produces scores that are shown to correlate well with manual scores used in educational assessment of students’ summaries. This motivates the development of a more accurate automated method to compute pyramid scores. Of three methods tested here, the one that performs best relies on latent semantics.

In DUC 2005, the pyramid method for content evaluation was used for the first time in a crosssite evaluation. We discuss the method used in creating pyramid models and performing peer annotation. Analysis of score averages for the peers indicates that the best systems score half as well as humans, and that systems can be grouped into better and worse performers. There were few significant diffe...

Halyomorpha halys (Stål) is an invasive pest that attacks numerous crops. For growers to make informed management decisions against H. halys, an effective monitoring tool must be in place. We evaluated various trap designs baited with the two-component aggregation pheromone of H. halys and synergist and deployed in commercial apple orchards. We compared our current experimental standard trap, a...

A mirror pyramid consists of a set of planar mirror faces arranged around an axis of symmetry and inclined to form a pyramid. By strategically positioning a number of conventional cameras around a mirror pyramid, the viewpoints of the cameras’ mirror images can be located at a single point within the pyramid and their optical axes pointed in different directions to effectively form a virtual ca...

This paper presents a novel image representation, which incorporates the principles of Laplacian Pyramid into the irregular graph pyramid. The drawback of the regular Laplacian Pyramid is their lack to keep the topological structure of the image, due to the contraction process in building the Gaussian Pyramid. Irregular graph pyramid is able to hierarchically represent the topological structure...

We present a new supervised framework that learns to estimate automatic Pyramid scores and uses them for optimizationbased extractive multi-document summarization. For learning automatic Pyramid scores, we developed a method for automatic training data generation which is based on a genetic algorithm using automatic Pyramid as the fitness function. Our experimental evaluation shows that our new...

The pyramid network is a hierarchy structure based on meshes. Chen et al. in 2004 proposed a new hierarchy structure, called the enhanced pyramid network, by replacing each mesh at layer greater than one of the pyramid network with a torus. This investigation demonstrates that the enhanced pyramid network with two faulty edges is Hamiltonian. The result is optimal because both edge connectivity...

A given (overcomplete) discrete oriented pyramid may be converted into a steerable pyramid by interpolation. We present a technique for deriving the optimal interpolation functions (otherwise called steering coefficients). The proposed scheme is demonstrated on a computationally efficient oriented pyramid, which is a variation on the Burt and Adelson pyramid. We apply the generated steerable py...

Pyramid annotation makes it possible to evaluate quantitatively and qualitatively the content of machine-generated (or human) summaries. Evaluation methods must prove themselves against the same measuring stick – evaluation – as other research methods. First, a formal assessment of pyramid data from the 2003 Document Understanding Conference (DUC) is presented; this addresses whether the form o...
