The problem of deening an eecient procedure to sort the magnets in a circular accelerator is considered. Using a simpliied model of the LHC, we analyze the eeects of random errors on the dynamic aperture. Diierent quality factors are proposed to measure the performances of a given lattice. These quantities are based on the analytical tools of nonlinear maps and normal forms. The correlation bet...

this study aimed to evaluate the potential of image ratioing techniques to detect and map the extent and particle composition of sand dunes in the erg of gavkhouni in isfahan province. the 6/4 ratio index and also a new index called sadi which was calculated using landsat band 3, 6 and 7 were applied to a georeferenced landsat tm image. to evaluate the performance of ratio techniques, the extra...

We present a new indexing method named ZINC (for Z-order Indexing with Nested Code) that supports efficient skyline computation for data with both totally and partially ordered attribute domains. The key innovation in ZINC is based on combining the strengths of the ZB-tree, which is the state-of-the-art index method for computing skylines involving totally ordered domains, with a novel, nested ...

The focus of this paper is to evaluate the benefits of a Japanese e-government project. In this research, the Importance-Performance Analysis (IPA) grid was used to measure the e-government benefits from the users’ perspective. A list of 27 government benefits was identified from the e-government literature reviews and each of the benefits was rated using a five point Likert scale. On a five po...

This article evaluates different improvements of Laurent Itti’s (Itti et al., 1998) visual attention model. Sixteen persons have participated in a qualitative evaluation protocol on a database of 48 images. Six different methods were evaluated, including a random fixations generation model. A real time conspicuity maps generation algorithm is also described. Evaluations show that this algorithm...

This paper presents a research project of University of Pavia that has been implemented by Business Integration Partners (BIP). The project concerns a Knowledge Base on Business and IT Processes. The Knowledge Base maps Business and related IT Processes and stores knowledge structures in different forms, such as diagrams, text, multimedia. The analyst can navigate stored information and create ...

Environmental performances of electricity generation, expressed as environmental impacts per kWh of electricity produced, depend strongly on technical, methodological and geographical parameters. When considering the global environmental performances of renewable energies, a geo-dependent life cycle assessment (LCA) taking into account geographical issues is of high interest. To illustrate this...
