In highly urbanized and energy intensive countries like Singapore all possible avenues for power generation need attention. In this context, rooftop installations of both solar and wind energy are of particular interest for Singapore, especially because of Singapore's condition of land limitation. Decentralized and distributed energy sources such as rooftop wind and solar installations have num...

Continuous, high-data-rate visual sensing and processing in the field is important for intelligent transportation, environmental monitoring, and area / context awareness. Rechargeable batteries in self-sustainable systems suffer from adverse environmental impact and fast aging. Advancements in supercapacitor energy density and low-power processors have reached an inflection point, where a data-...

The price of electricity supplied from home rooftop photo voltaic (PV) solar cells has fallen below the retail price of grid electricity in some areas. A number of residential households have an economic incentive to install rooftop PV systems and reduce their purchases of electricity from the grid. A significant portion of the costs incurred by utility companies are fixed costs which must be r...

Steady-state RANS Computational Fluid Dynamics simulations of pollutant dispersion in the neutrally stable atmospheric boundary layer are made with the commercial code Fluent 6.1 for three case studies: plume dispersion from an isolated stack, low-momentum exhaust from a rooftop vent on an isolated cubic building model and high-momentum exhaust from a rooftop stack on a low-rise rectangular bui...

Information on the diversity of fungal spores in air is limited, and also the content of airborne spores of fungal plant pathogens is understudied. In the present study, a total of 152 air samples were taken from rooftops at urban settings in Slagelse, DK, Wageningen NL, and Rothamsted, UK together with 41 samples from above oilseed rape fields in Rothamsted. Samples were taken during 10-day pe...

The main approach to design flood estimation in Australia is event-based with the use of flood hydrograph models such as RORB, WBNM and URBS the most common practice for estimating design floods via rainfall based approaches. A characteristic of these models is that the routing of rainfall excess is distributed within the catchment, the amount of routing depending on the amount of sub-division ...

Storm Water Management Model (SWMM) is a digital hydrological model which is widely used for the simulation of rainfall-runoff processes in urban catchment. SWMM is a distributed model, which means a study urban catchment needs to be divided into several irregular subcatchments first before simulation. However, most of the existing subcatchments division approaches for the SWMM are not able to ...

Landholders, departmental agencies and other stakeholders have long been involved in knowledge building of the physical elements affecting land use. Often, however, this has been without any accompanying information on social and economic impacts, or systems for exploring catchment trade-off decisions. RIMIS is the concept of a regional management system designed for landscape managers. It has ...
