Strategic long-term planning of mountain forests in the European Alps requires a balancing act between sustaining forest biodiversity and ecosystem services (BES) and mitigating disturbance risks, particularly under climate change. Multi-criteria decision support systems (DSSs) address this challeng...

Mô tả đầy đủ

Fire doors are installed between compartments to prevent the spread of fire. During a fire, the temperature difference between the exposed and unexposed surfaces induces bending deformation of the door, thereby reducing its fire resistance performance. Excessive deformation may further compromise th...

Wireless Fire Security System increases the secu-rity against fire as compared to conventional fire security systems. Conventional fire security systems are wired and they usually contain smoke detectors and control panel. The control panel is sometimes hard to operate. It’s hard to understand the...

Mô tả đầy đủ

Computer simulation of the initial fire stages in closed compartment with the volume of ≈ 60 m3 and with a burner on a floor and 2 m above floor have been carried using FDS software. Fires with different t 2 –power low heat release rates have been modeled. Fires which growth times to reach 1055 kW w...

Forest fires in the Hindu Kush Himalaya (HKH) region are increasing in frequency and severity, driven by climate variability, prolonged dry periods, and human activity. Nepal, a critical part of the HKH, recorded over 22,700 forest fire events in the past decade, with fire incidence nearly doubling...

A critical analysis of the main provisions of normative documents in fire safety and explosion premises and buildings for technological gas pressure regulating devices are made. Preventive recommendations are given.

The almost complete eradication of fire from grasslands in North America has led to non-linear hysteretic transitions to shrub- and woodlands that the reintroduction of low-intensity fire is unable to reverse. We explore the ability of the extreme ends of variation in fire behavior to help overcome...

Aim: In the case under consideration, research was conducted to optimize the design process of fire protection for an underwater sea tunnel to reduce potential fire risks and enhance the resistance of fire protection pipelines to corrosion caused by seawater. Introduction: Designing intelligent fire...

The fire resistance performance of steel beams is of utmost importance to the fire safety of building structures and personnel evacuation. To address the deviation in the assumption of uniform temperature distribution in traditional studies, this study conducted multiple simulation tests. It was fou...

Mô tả đầy đủ

Firebreaks and fuel treatments are critical means for the reduction of wildfire threat and damage to human infrastructure in forest landscapes. However, the uncertain behavior of wildfires makes the planning of firebreaks challenging, especially when available resources are insufficient to treat all...

Fire scenario simulation in residential buildings is crucial for fire safety design, risk assessment, and emergency management. Traditional CFD-based methods face challenges, including long computation times and reliance on expertise, limiting their use for real-time prediction and rapid design opti...
