Abstract: Constant-force mechanisms (CFMs) can produce an almost invariant output force over a limited range of input displacement. Without using additional sensor and force controller, adjustable CFMs can passively produce an ...

Abstract: This study explores the elastoplastic deformational behavior of gravelly soils. A series of drained triaxial tests with controlled stress paths [conventional triaxial compression (CTC) and conventional triaxial extension ...

Abstract: This study aims to satisfy the energy management contract (EMC) work schedule of the Ministry of Transport (MOT). The paper first defines EMC together with its connotations to clarify its specific demands for the market ...

Abstract: It is usual that fuel system of an aeroengine operates within a wide range of temperatures. As a result, this can have effect on both the characteristics and precision of fuel metering unit (FMU), even on the performance ...

Abstract: This study investigated the hydraulic conductivity and microscopic properties of two backfills, conventional sand/bentonite (SB) and sand/xanthan gum (XG)-amended bentonite/sand (XG-SB), for use in vertical cutoff walls ...

Abstract: The construction industry has been significantly impacted by the economic, financial, and operational consequences of the COVID-19 pandemic. Because the pandemic continues to evolve, this study aimed to better understand ...

Abstract: The planning of a metro network layout is important in alleviating traffic congestion, guiding land exploitation, and promoting urban development. This paper proposes a hybrid model of two-phase formulation based on path ...

Abstract: Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium chloride (CaCl2) solutions was investigated to access its chemical compatibility in vertical cutoff walls application. PB was synthesized ...
