“…With a sufficient amount of data, it will be possible to derive a mathematical equation to express this effect. The inclusion of the bust impact on the pressure generated by the explosion, to the process of risk assessment of critical infrastructure objects or other objects important for the state and society and soft targets, allow this process, such an approach is described in detail in [23][24][25][26]. In this way, the risk assessment can be adapted to the variability of how the attack is carried out and the possibilities of the offender.…”

Most of the damage caused by an explosion is caused by a pressure effect. The magnitude of the pressure generated by the explosion is influenced by the external characteristics of the environment (surrounding objects, their arrangement, geometry, etc.) and internal characteristics (type of explosive, type of charge, booster and others). An effective combination of internal factors creates a symmetry that results in the highest possible value of pressure generated by the charge explosion. The paper focuses on the influence of the booster reaction on this symmetry. The scope of the paper is to understand the dependency of the blast wave pressure on the amount of used blaster to increase the efficacy of explosions on the environment and structures to increase the protection of affected structures. The open-air field tests were conducted using different types of explosives: trinitrotoluene and three different types of industrially made ANFO explosives (pure ammonium nitrate and fuel oil, ammonium nitrate and fuel oil plus aluminum powder, ammonium nitrate and fuel oil mixed with trinitrotoluene). The obtained data were compared with the analytical approach for setting the generated maximal pressure on the front of the blast wave.

“…Networking and communication-based operation will also have an increasingly important role in railway systems. A large amount of data [38] generated by the network-based operation will be automatically transformed into information allowing the basic forms of automatic operation in the railway system. In conclusion, the use of machine intelligence will lead to increased efficiency, sustainability and safety in transportation in the future.…”

The present article focuses on the research and development planning for innovative railway systems. Within such a general framework, the specific objectives of the research have been defined within the framework of a large Intelligent Railway System project in Hungary. Our theoretical research work at the university is combined with practical experience gained at the Hungarian State Railways. In the course of this research work, the development of an intelligent railway system has been investigated by leveraging on the fruitful cooperation between academic and industrial partners, in order to promote the application and integration possibilities of the development results, as well as the introduction of innovative components in the railway system. In such a context, this article discusses the research plan, preliminary and long-term expected results, sharing objectives and experiences with the aim of providing novel views in an extremely current and challenging field of research.

“…The surface roughness and heat caused changes in both microstructure and corrosion resistance. This process was modelled by la-boratory experiments [9][10][11]. The tested samples were treated in FeIIICl solution (ASTM A 262), for 96 hours at 30 ºC.…”

It is known that fusion welding can cause a decrease in the corrosion resistance of the heat affected zone of unstabilized stainless steels. The reason for this problem is that the welding heat (in the heat affected zone (HAZ)) can cause chromium-carbide (Cr23C6) precipitation with the simultaneous reduction of chromium content at the local grain boundaries. The chromium content dictates the corrosion resistance level. The relationship between surface roughness and corrosion behaviour is well known. We sought to find the difference between the corrosion resistance and surface roughness relationship in the case of cold rolled stainless steel and in the case of heat treated (welding heat effect simulated) stainless steel [1-3].
