While the importance of spatial scale in ecology is well established, few studies have investigated the impact of data grain on conservation planning outcomes. In this study, we compared species richness hotspot and representation networks developed at five grain sizes. We used species distribution maps for mammals and birds developed by the Arizona and New Mexico Gap Analysis Programs (GAP) to...

This report gives a high level overview of the Graal JIT compiler developed in Oracle Labs in collaboration with the Institute for System Software at the Johannes Kepler University. Graal is written in Java and aims at replacing or complementing the HotSpot server and client compilers. I’ll introduce the main concepts of how Graal works and bring out the biggest differences to the current HotSp...

As advanced technologies in wafer manufacturing push patterning processes toward lower-k1 subwavelength printing, lithography for mass production potentially suffers from decreased patterning fidelity. This results in generation of many hotspots, which are actual device patterns with relatively large CD and image errors with respect to on-wafer targets. Hotspots can be formed under a variety of...

In this thesis, the phenomenon of localized crime hotspots in models capturing the repeat and near-victimization nature of urban crime was studied. Stability, insertion, slow movement of crime hotspots and the effect of police patrol modeled by an extra equation derived from biased random walk were studied by means of matched asymptotic expansions, nonlocal eigenvalue problem (NLEP) stability a...

The performance of Multistage Interconnection Networks (MINs) under hotspot traffic, where some percentage of the traffic is targeted at single nodes, which are also called hot spots, is of crucial interest. The prioritizing of packets has already been proposed at previous works as alleviation to the tree saturation problem, leading to a scheme that natively supports 2-class priority traffic. I...
