an arch is preferred over other structural members owing to its greater performance. Concrete arch structures are often used in the construction of various underground protective projects. The research on how to improve the anti-blast performance of concrete arches and optimize the design of protective...
The single degree of freedom (SDOF) system which simplifies the motion of the continuum structure into the one-dimensional motion of the feature direction is brought into the design of anti-blast structures. This method can also quickly present the maximum deflection, speed and acceleration of the...
using the pooled colony design, would be found to be selective for colonies containing many new clonogenic cells. This possibility was examined by replating single colonies from control cultures or cultures containing either 5-aza or 6-aza. Data shown inFig 3are from a representative experiment ...
Design length of the chute (m) lα Effective length of the chute, i.e. the actual moving length of the burden on the chute (m) m Mass of the burden particle (kg) m1 Mass of the burden, calculated from the equivalent diameter of the burden stream (kg) n Number of collisions of th...
where Lis the length of the peripheral hole (m), δis the angle of the peripheral hole according to the actual value (°), and eis the error between the hole position and design position (opening error) (m). From the comprehensive analysis formulas in Eqs. (1), (7), and (8),...
absorb part of the blast energy (seeFigure 1). When the blast wave reaches the building, the façade panel is loaded and triggers the set of connectors that start to absorb the kinetic energy transmitted by the explosion. Depending on the blast magnitude and the design of the connecting ...
Unlike neural networks, XGBoost uses the same overall design for every single model, and the model only has to calculate the derivative once (on paper), where we will know that it will work for all of the models created. In contrast, every neural network can have a different design (such...
To accurately predict the response of a prototype, it is crucial to employ an appropriate similarity law to design a scale-down model. Due to the nonlinear effects involved in explosion scenarios, the similarity π-theorem is widely used to simplify problems [8,9]. The method posits that when...

Of course, it would be expedient to apply concrete with these improved properties in practice in design and construction. 3.3. Analysis of the Hardened Cement Paste Microstructure of Vibrocentrifuged Concrete Modified with the Addition of GBFS This research of the microstructure was carried out to...
