Fire Design of Concrete Structures based on a Levels-of-Approximation Approach

Miguel Fernández Ruiz, Miguel Gomez

Concrete structures, contrary to steel or timber structures, have not been traditionally considered as significantly sensitive to fire conditions. As a consequence, their performance in fire conditions has generally been assessed on the basis of quite simp ...

Robotic training for hand movements during manual welding with real-time alarm feedback

Aude Billard, Mustafa Suphi Erden

Purpose - The purpose of this study is to develop a robotic training system for the hand movements during manual welding. The system provides real-time notice-feedback with sound or light alarms, whenever the welding hand vibrates beyond the nominal level ...

A model for global biomass burning in preindustrial time: LPJ-LMfire (v1.0)

Jed Oliver Kaplan, Mirjam Pfeiffer

Fire is the primary disturbance factor in many terrestrial ecosystems. Wildfire alters vegetation structure and composition, affects carbon storage and biogeochemical cycling, and results in the release of climatically relevant trace gases including CO2, C ...

Predictability of biomass burning in response to climate changes

Basil Andrew Stansfield Davis, Christopher Michael Long, Yi Zhang

Climate is an important control on biomass burning, but the sensitivity of fire to changes in temperature and moisture balance has not been quantified. We analyze sedimentary charcoal records to show that the changes in fire regime over the past 21,000 yrs ...

Fire performance of water-cooled GFRP columns. Part I: Fire endurance investigation

Thomas Keller, Yu Bai, Christian Ludwig

Structural fire endurance experiments were conducted on full-scale cellular glass fiber-reinforced (GFRP) columns under axial compression and subjected to ISO834 fire exposure from one side. Unprotected columns can resist fire for more than 30 min, which i ...

Forest fire localization using distributed algorithms in wireless sensor networks

Martin Hasler, Alireza Khadivi, Leonidas Georgopoulos

The fire localization using a distributed consensus finding algorithm in a wireless sensor network is described. The fire is circumscribed by a circle. The information is available at all sensor nodes that are alive, which makes it robust against failures ...
