We characterized wildfire transmission and exposure within a matrix of large land tenures (federal, state, and private) surrounding 56 communities within a 3.3 million ha fire prone region of central Oregon US. Wildfire simulation and network analysis were used to quantify the exchange of fire among land tenures and communities and analyze the relative contributions of human versus natural igni...
The paper is concerned with a dynamic blocking problem, originally motivated by the control of wild fires. It is assumed that the region R(t) ⊂ R burned by the fire is initially a disc, and expands with unit speed in all directions. To block the fire, a barrier Γ can be constructed in real time, so that the portion of the barrier constructed within time t has length ≤ σt, for some constant σ > ...
Fire is pervasive in forests used by California Spotted Owls (Strix occidentalis occidentalis) and their prey species. We assessed the diets and sizes of the breeding-season home ranges of seven Spotted Owls occupying burned forests in the southern Sierra Nevada 4 years after a fire and compared the results with data from previous studies in unburned forests within the range of the subspecies. ...
Background: Albumin is one of the most important proteins in the body by several important functions, it is essential in the maintenance of normal plasma colloid oncotic pressure and is the primary serum binding protein responsible for the transport of various substances in the circulation including fatty acids, hormones, and drugs. Decrease in the amount of serum Albumin (Hypoalbuminemia) is a...
Epidemiological Study and Mortality of Burned Patients Hospitalized in Imam Musa Kazim Hospital, Isfahan, Iran During the years 2014 -2017 Abstract Introduction: Burn gives rise the high mortality and socio-economic burdens. This study aimed to assesses epidemiological characteristics of burn patients and their relationship with mortality caused by burn. Methods:This descriptive-analytic ...
We consider a class of variational problems for differential inclusions, related to the control of wild fires. The area burned by the fire at time t > 0 is modelled as the reachable set for a differential inclusion ẋ ∈ F (x), starting from an initial set R0. To block the fire, a barrier can be constructed progressively in time. For each t > 0, the portion of the wall constructed within time t i...
The lack of extensive research in the application of inexpensive wireless sensor nodes for the early detection of wildfires motivated us to investigate the cost of such a network. As a first step, in this paper we present several results which relate the time to detection and the burned area to the number of sensor nodes in the region which is protected. We prove that the probability distributi...
After more than two decades of successful provision global burned area data the MODIS mission is near to its end. Therefore, using alternative images generate moderate resolution maps becomes critical guarantee temporal continuity these products. This paper presents development a hybrid algorithm based on Copernicus Sentinel-3 (S3) Synergy (SYN) and Visible Infrared Imaging Radiometer Suite (VI...
