Deep Underground Science and Engineering, EarlyView.Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Damping Modification Factors for Pile–Induced Filtering Effect
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...

Development of a Novel Modified Mean‐Line Approach for Performance Prediction of Axial Compressors
Energy Science &Engineering, EarlyView.ABSTRACT There is significant importance in accurate prediction of axial flow compressor characteristics at different conditions. Different techniques and models have been proposed for performance prediction of axial compressors. Because of its lower computational cost and high speed the meanline algorithm has been widely applied in preliminary design ...

Energy Science &Engineering, EarlyView.ABSTRACT This study aims to model a solar power plant (SPP) utilizing parabolic trough collectors (PTC) to fulfill the electricity needs in an arid zone of the southern of Tunisia. The research integrates both experimental and numerical approaches. A prototype of a PTC was first constructed and experimentally tested under arid climates. Subsequently, a
