Risk management of induced micro-seismicity caused by hydraulic fracturing through acoustic emission Yuan, Feng1, a, Chaoyin, Feng2, b 1School of Civil Engineering, Beijing Jiaotong University, Beijing 100044, China 2Xuchang Vocational Technical College, Xuchang 461000, China afengyuan.energy@gmail.com, bfcy641213@yahoo.com.cn Keywords: Acoustic emission; Risk assessment; Hydraulic fracturing Abstract.
The AE monitors have some peerless advantages in geo-engineering.
Besides, experienced engineering can be invited to offer the risk probability.
In practical engineering, the engineering treatments must be combined with the economic benefits.
The logic process of risk management in practical engineering is imaged.

The Role of Nanoparticles on the Durability of Lime-Pozzolan Binding System Eirini- Chrysanthi Tsardaka1,a*, Eleni Pavlidou2, Maria Stefanidou1 1Laboratory of Building Materials, Dept. of Civil Engineering, AUTH, Thessaloniki, Greece 2Dept. of Physics, AUTH, Thessaloniki, Greece aextsardaka@gmail.com, belpavlid@auth.gr, cstefan@civil.auth.gr Keywords: nano-silica, nano-alumina, nano-calcium oxide, traditional binders, durability Abstract.

For another, among related majors or disciplines such as the planning discipline, civil engineering, environment management, and other science engineering, humanity and arts, the substantial communication is insufficient.
The Construction of Scientific Questions of Urban Planning Study Generally speaking, there rarely exist rigorous scientific questions in Urban Planning discipline as it is one of engineering and technology disciplines, dealing with problems of practical engineering or technological application.
As pointed in the 2009 Application Guide of 973 National Plan, “it is necessary to do research on basic scientific questions involving the ecology, engineering safety, environment and engineer control on urbanizing western hilly rural areas”; “it is necessary to do research on the basic scientific questions concerning urban underground projects and the safety of urban building clusters” etc..
In general, the emphasis of Architecture has always been on Urban Planning Study of architecture engineering, and the teaching model is built on the morphology theory of urban material space and practical research.
Besides, it is also necessary to continue to upgrade the teaching model of Urban Planning of Architecture Engineering in different aspects such as the curriculum systems, teaching process and teaching evaluation indices.

However, it appears that American maintenance engineers are more prone to rely on computerized tools compared to European engineers.
European engineers more depending on human judgments.
The recommended BMS staff positions are design and rating engineer, IT staff, data Entry Staffs, support and maintenance engineer, finance/planning staff and academia/researchers. ii.
