PURPOSE To compare the preferential hyperacuity perimeter (Preview PHP; Carl Zeiss Meditec, Dublin, CA) with the original Amsler grid in the detection of choroidal neovascularization (CNV) in patients with age-related macular degeneration (AMD). METHODS Patients were classified into groups, based on the severity of the age-related macular degeneration and underwent preferential hyperacuity pe...

The type of business relationships between the Internet autonomous systems (AS) determines the BGP interdomain routing. Previous works on inferring AS relationships relied on the connectivity information between ASes. In this paper we infer AS relationships by analysing the routing polices of ASes encoded in the BGP attributes Communities and the Locpref. We accumulate BGP data from RouteViews,...

We consider the autonomous system (AS) path prepending (ASPP) approach to perform load-balancing on inbound traffic for multihomed ASes. Although the ASPP approach has been practiced by many AS operators for a long time, it is surprising that there still lacks a systematic study of the approach and understanding of its effects and performance implications. The purpose of this paper is to provid...

We discuss how simultaneous observations by multiple heliospheric imagers can provide some important information about the azimuthal properties of Coronal Mass Ejections (CMEs) in the heliosphere. We propose two simple models of CME geometry that can be used to derive information about the azimuthal deflection and the azimuthal expansion of CMEs from SECCHI/HI observations. We apply these two m...

We have witnessed successes of production grids and various grid applications in last decade. Motivated by previous and current grid initiatives and raising science community demands for computing resources, project CRO-GRID was initiated. CRO-GRID is a national multi-project whose goals are introduction of grid and cluster technologies to science community and industry and development of distr...

The original edition of What Computers Can’t Do comprised three roughly equal parts: (i) a harsh critical survey of the history and state of the art in AI, circa 1970; (ii) a brilliant philosophical expose’ of four hidden assumptions shoring up AI’s misplaced optimism; and (iii) a much more tentative exploration of ways to think #about intelligence without those assumptions. Part I, because it ...

The BGP dataset contains a collection of AS paths describing the Internet inter-domain routing information. It is publically accessible at RIPE and RouteViews project websites. For the sake of easy processing, you could use the BGP data collected in January 2014. The raw dataset is stored in a compressed BGP format. To obtain human-readable data, you need to process the dataset using the bgpdum...
