Asterisk indicates corresponding author (when not the first author). Locations indicated for first authors only. Mauricio Acuna, Cristian Palma, Wenbin Cui, David Martell *, Andres Weintraub Universidad de Chile, Santiago “Integrated timber harvest and fire management planning” Harvest planners often consider potential fire losses and timber production plans can influence fire management but mo...
Covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. While numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. Random generation techniques c...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Designing and producing a proper fusion construction is the most important problem of producing large quantities of a properly folded functional protein. This construction should have all necessary components of a real gene. A good designed fusion gene construction could be cloned into a good and suitable host. Clostridium perfringens is an important pathogen of humans and livestock and produce...
This study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. The resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. But by increasingof fire retar...
Introduction: Extensive human and economic losses due to the fire accidents shows the necessity of scientifically dealing with major industrial fires, , investing in the development of fire protection technologies and determination of the most effective techniques to limit damages. This study is conducted to evaluate the effect of active and passive protection methods on reducing the level of f...
This research paper aspired to design and develop a gas leakage fire monitoring detection alarm system based on SMS. Most incidents in houses, schools factories are caused by leakage. Many houses being destroyed To prevent the loss of life properties, preventive measures should be taken, hence this was conceptualized. The installation GF (Gas Fire) alert vulnerable locations may help lessen if ...
Research in wireless sensor networks (WSNs) has experienced a significant growth in recent years. One topic of special interest is the use of WSNs in the detection of forest fire as it is a common disastrous phenomenon that constitutes a serious threat. Numerous detection mechanisms are available for forest fire in the literature using wireless sensor networks and other methods. The work presen...
Numerous theoretical and empirical studies have shown that wildfire activity (e.g., area burned) at regional to global scales may be limited at the extremes of environmental gradients such as productivity or moisture. Fire activity, however, represents only one component of the fire regime, and no studies to date have characterized fire severity along such gradients. Given the importance of fir...
