Skateparks are undeniably youth-orientated spaces where contoured bowls, smooth concrete, steep ramps and angled ledges carry the embodied expectation that the sole purpose of the space is for skateboarding. Upon close inspection though, visible signs and traces reveal other activities occurring – meeting up, hanging out, hooking up, dropping out, graffiti-ing and worshiping, to name a few. Thi...

This paper describes the results of IP traffic traces taken within a departmental LAN over a 16 day period. This traffic is used to drive a model of IP-overATM to analyse the real efficiency of the technique. We propose a new method of analysing the resultant ATM traffic, and conclude that cell utilisation is higher than would be predicted with WAN traffic. We also show that RFC1144 header comp...

We present a new acceleration structure for ray tracing called the Split Grid. Combining concepts of hierarchical grids, kd-trees and Bounding Volume Hierarchies (BVHs), our approach is based on the idea of nesting 1D-grids. Our proposed acceleration structure is compact in storage, adaptive to the scene geometry and can be traversed using a fast and efficient traversal scheme. We show that the...

ecological footprint analysis in agriculture is a new and evolving subject. the main purpose of the study was to assess environmental sustainability of conventional and conservation tillage systems using ecological footprint analysis in hamedan province. global hectares (gha) were used to measure the ecological footprint unit. data was collected through questionnaires and use of cross-sectional...

Over the last decade footprint feature extraction has been actively researched for footprint recognition. This paper provides an up-to-date review of major human footprint recognition research. In Earlier sections, we have presented an overview of footprint recognition and its applications. In later sections, literature review of the most recent footprint recognition technique is presented. The...

Today’s cloud data center infrastructures are not even near being able to cope with the enormous and rapidly varying capacity demands that will be reality in a near future. So far, very little is understood about how to transform today’s data centers (being large, power-hungry facilities, and operated through heroic efforts by numerous administrators) into a self-managed, dynamic, and dependabl...
