Mechanism analysis and prevention method for tunnel fire Jing Wu1,a,Feimin Shen1,b, Ping Jiang1,c 1College of Civil Engineering, Fuzhou University, Fuzhou, Fujian 350108, China awujingcqu@163.com, b1003474815@qq.com, c13696867456@163.com Keywords:Tunnel fire; Spontaneous combustion; Ambient temperature; Ventilation; Combustibles Abstract:By analyzing the typical fire casesand tunnel fire statistics during 2008 to 2013 in Fujianprovince of China, results shows that the main causesfor the fire were vehicle accidents and spontaneous combustion.
Introduction In recent years, with the rapid development of the transport industry, tunnels are emerging and the trafficsare increasing.The number and the frequency of vehicles which carrying all kinds of combustible material through tunnel is growing, and also the frequency of tunnel fire is increasing year by year.
Combined with the types of flammable materials and combustion state, the tunnel fires classificationsare shown in Table 4.
In short, the maximum temperature and the product concentration in the reaction zone are the key parameters when solid combustible turn into the fire.
Most of the fires are simultaneously burning several combustible materials.

However, the latter materials have many essential characteristics.
Materials and Methods The objective of this study is to create a FeAl binary alloy.

As an important part of earthquake disaster relief, highway traffic system is the passage for rescue staffs, material transport and evacuation.
On one hand, key factors with great influence cannot be omitted; on the other, there shall not be too many evaluation indicators, which will bring great difficulties to evaluation and will not achieve ideal effect.
According to the survey and analysis to post-seismic highway subgrade damage characteristics and consulting of the Provisions on Evaluation to Seismic Damage Loss (Tentative), Post-earthquake Field Works series, Technical Guidance on Post-disaster Highway Recovery and Reconstruction of Wenchuan Earthquake, Classification of Earthquake Damage to Lifeline Engineering (GB/T24336-2009) and other related literature and data, the Paper classifies seismic damages of subgrade principal part, slope and retaining structures into 5 grades.

Electrothermal Modelling and Measurements of Parallel-Connected VTH Mismatched SiC MOSFETs under Inductive Load Switching Simon Mendy1,a, Ruizhu Wu1,b, Jose Ortiz Gonzalez1,c, Olayiwola Alatise1, d 1School of Engineering, University of Warwick, Coventry, United Kingdom as.mendy@warwick.ac.uk, brobert.wu.1@warwick.ac.uk, cj.a.ortiz-gonzalez@warwick.ac.uk, do.alatise@warwick.ac.uk Keywords: SiC MOSFETs, FET, threshold voltage mismatch, gate synchronisation, current sharing, parallel-connected MOSFETs, inductive load switching, device under test - DUT Abstract In high current applications that use several parallel-connected SiC MOSFETs (e.g., automotive traction inverters), optimal current sharing is integral to overall system reliability.
While design engineers have traditionally used SPICE based models as diagnostic tools, their application depends on model availability and ease of parameter tuning.
The material constant, K, contains μ, which is overdrive voltage and temperature-dependent [12].

The known key problem for these missions is the appropriate attitude control (AC) of the orbital platform that has to be assured through a low mass, low cost controller and effector, in contrast to the much larger applications from weather satellites to the Hubble Orbital Observatory.
Within the ADDA ground test facility the actual dynamics of the inertial, guided platform is explored, where the controller of the attitude is learned to act based on the equations of motion, with active thrusters driven along the time intervals where the binary flags δk are on (δk=1), (1) Volume integrals are performed into the mobile, material control volumes υk, which the observer preserves a fixed position with.

It is, therefore, desired that a new method to fabricate bulky UFGed metallic materials more easily shall be invented.
The above experimental results suggest, therefore, adequate combination of material and testing condition is a key to utilize deformation twins for UFG evolution.
It is known that SPD materials possess quite high strength but poor ductility.
The twins appear more frequently in the low SFE metallic materials when deformed at low temperature and at high strain rate.
