The possibility of employing the same spacecraft at several orbital locations, changing the coverage region, and compensating for varying weather conditions are the main reasons why reconfigurable antennas for contoured beam generation can provide significant advantages in satellite communications. Though extremely attractive in terms of cost and manufacturing, shaped reflectors lack so far the...

This paper describes the findings from an exploratory case study into the business processes at a leading Australian insurance provider. The business processes are frequently subjected to changes and deviations due to contextual events such as weather, financial conditions and others. In this study, we examine how context impacts business processes and how resulting business process changes are...

A technique for detection of building images in real-world video sequences is presented. The proposed technique uses information extracted from video features to improve precision in classification results. It combines fuzzy rule-based classification with a method for changing region detection in outdoor environments, which is invariant to extreme illumination changes and severe weather conditi...

Pacific Islanders have historically managed living with extreme weather. But changing climatic conditions due to human-induced influences appear certain to change their worlds. In fact, changes are already evident. In a world that is largely struggling with rapid urbanization, lack of sanitation infrastructure, scarce water resources and extensive poverty, the changes to come will continue maki...

Seasonal and inter-annual climate variability have become important issues for farmers, and climate change has been shown to increase them. Simultaneously farmers and agricultural organizations are increasingly collecting observational data about in situ crop performance. Agriculture thus needs new tools to cope with changing environmental conditions and to take advantage of these data. Data mi...

The paper describes a concept for GIS based terrain mobility modelling and optimization of off-road route. The concept of generation of cost surface is based on machine, terrain, tree coverage, road and weather objects. Different cost surface alternatives can be generated according to changing information in objects. A regular costpath analysis is used to determine alternative routes in differe...

The relative importance of fuel, topography, and weather on fire spread varies at different spatial scales, but how the relative importance of these controls respond to changing spatial scales is poorly understood. We designed a "moving window" resampling technique that allowed us to quantify the relative importance of controls on fire spread at continuous spatial scales using boosted regressio...

Wider scientific community now accept that the threat of climate change as real and thus acknowledge the importance of implementing adaptation measures in a global context. In the UK, the physical effects of climate change are likely to be directly felt in the form of extreme weather events, which are predicted to escalate in number and severity in future under the changing climatic conditions....
