Catchment urbanisation leads to increased hydraulic and pollutant loadings into receiving waterbodies. Issues concerning pollution that endangers the sustainable utilisation of water resources have focused government authorities towards integrated catchment management, where both causes and effects of pollution are addressed. Recent research has provided a platform for improving urban stormwate...

Initiatives to displace petroleum and climate change mitigation have driven a recent increase in space heating with biomass combustion. However, there is ample evidence that biomass combustion emits significant quantities of health damaging pollutants. We investigated the near-source micro-environmental air quality impact of a biomass-fueled combined heat and power system equipped with an elect...

Automatic recognition and reconstruction of buildings from aerial and space images is of great practical interest for many of applications such as cartography and photo-interpretation. Building detection is the first and very difficult step in building recognition and reconstruction. It is to find buildings and separating them from the background in the presence of distractions caused by other ...

â â â  parsian alluvial fan system is a part of asyab-kharabeh fluvial system that response it to quaternary climate changes is the main goal of this study. for this aim, climatic proxies and traces in alluvial fan structure were investigated base d o n four categories: aggradation and degradation phases, debris flows, size changes in deposited materials and formation of alluvial fan tufas. pri...

This study represents advancements in the state-of-the-art of the solar energy industry by leveraging LiDAR-based building characterization for city-wide, distributed solar photovoltaics, solar maps, highlighting the distribution of solar energy across the city of San Antonio. A methodology is implemented to systematically derive the tilt and azimuth angles of each rooftop and to quantify solar...

Water resources are rapidly declining in Malaysia due to various challenges such as climate change, pollution, urbanisation, and high-water domestic consumption. On the other hand, water conservation initiatives mainly concentrated commercial residential buildings while public schools have been underutilized. Malaysian seen be able conserve a significant amount of manage supply responsibly, giv...

We consider the problem of detecting rooftops in overhead images, which is one processing step in a building detection system. Currently, the system uses a hand-configured linear classifier to select the most promising rooftop candidates for further processing. We present results from an empirical study in which we used machine learning methods to acquire the selection criteria for rooftops. RO...

This extended abstract describes our experiences from constructing the MIT Roofnet, an experimental rooftop wireless network. The ultimate goal of Roofnet is to build an ad-hoc network infrastructure capable of providing pervasive highspeed network access. Currently, the network currently consists of more than 35 nodes spread over two square kilometers of Cambridge, MA. The network is self-conf...
