We present the architecture, implementation, and initial results from a live, continuous energy auditing system. By combining QR codes and mobile phones, we are able to iteratively collect building plug-load information and couple it with live, streaming meter data. The system consists of a deployment of inexpensive tags (QR codes) as well a smartphone-based auditing application. The mobile pho...

Cloud computing is a new paradigm for hosting and delivering services on demand over the internet where users access services. It is an example of an ultimately virtualized system, and a natural evolution for data centers that employ automated systems management, workload balancing, and virtualization technologies. Live virtual machine (VM) migration is a technique to achieve load balancing in ...

For the last couple of years, due to ecological as well as economical reasons, energy efficiency of ICT has become a major issue. Leading manufacturers of IT equipment advertise with ”green” and energy-efficient products. Steadily increasing energy consumption in data centers [1], as well as high electricity costs prompt organizations, companies, and administration to decrease the energy consum...

Bridge codes adopt values for dynamic allowance in traffic load models that are necessarily conservative to cover for an entire range of bridges with different mechanical characteristics, boundary conditions, and the large number of uncertainties associated to the vehicle-bridge interaction problem. A further level of conservatism occurs due to the independent manner in which the governing stat...

Truck size and weight regulations have been a key instrument used to improve trucking productivity, safety, operational performance in Canada. In response these changes, bridge design codes undergo modifications envelop the potential range of trucks operation. A five-decade timeline is presented: (1) document how their live load models evolved, with focus on Manitoba-specific HSS-25 truck, (2) ...

Fire behaviour models are used to assess the potential characteristics of wildland fires such as rates of spread, fireline intensity and flame length. These calculations help support fire management strategies while keeping fireline personnel safe. Live fuel moisture is an important component of fire behaviour models but the sensitivity of existing models to live fuel moisture has not been thor...
