Confeego is a suite of tools to understand and harness the effects of spatial configuration in urban systems or complex buildings developed by Space Syntax Limited and is available free for academic use. Confeego has been developed to support the various phases of a consultancy or research project and in that sense consists of several tools that are grouped according to the type of tasks involv...

We propose a new methodology to estimate the spatial reuse of CSMA-like scheduling. Instead of focusing on spatial configurations of users, we model the interferences between users as a random graph. Using configuration models for random graphs, we show how the properties of the medium access mechanism are captured by some deterministic differential equations, when the size of the graph gets la...

The importance of small urban parks (SUP) in mega cities has been accepted as an essential component of urban lung and restorative settings. As urban population in the world increases and the cost of maintaining large parks escalates, urban authorities are shifting their attention to creating and maintaining smaller urban parks. However, SUP may present a different ambience due to their locatio...

Newer spatial technologies, such as spatio-temporal databases, geo-sensor networks, and other remote sensing methods, require mechanisms to efficiently process spatial data and identify (and in some cases fix) data items that do not conform to rigorously defined spatial data type definitions. In this paper, we propose an O(n lg n) time complexity algorithm that examines a spatial configuration,...

We present a simple configuration incorporating a single polarization-sensitive phase-only liquid crystal spatial light modulator (LC-SLM) to facilitate polarization-insensitive spatial light modulation. The polarization-insensitive configuration is formed by a polarization beam splitter (PBS), a polarization-sensitive phase-only LC-SLM, a half-wave plate (HWP), and a mirror in a loop structure...

in this research, temporal and spatial behavior of siberian high (sh) was studied at the level of 1000 h.pa. this study has been done using daily data of geo potential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the mean geo p...

Exploratory activity was examined in 4 young baboons with the aim of investigating the type of spatial coding (purely geometric and/or by taking into account the identity of the object) used for the configuration of objects. Animals were individually tested in an outdoor enclosure for their exploratory reactions (contact time and order of spontaneous visits) to changes brought about to a config...
