Abstract Researchers face difficulties in studying the effects of driveline efficiency on car fuel economy via bench and road tests because of long working periods, high costs, and heavy workloads. To simplify the study ...

Abstract Current research on the dynamics and vibrations of geared rotor systems primarily focuses on deterministic models. However, uncertainties inevitably exist in the gear system, which cause uncertainties in system ...

Abstract The aim of this paper is to study the effect of agitator’s types on the turbulent flows in stirred tanks without and with baffles. The hydrodynamics behavior induced by four different agitator’s types: a Rus...

Abstract The existing engineering empirical life analysis models are not capable of considering the constitutive behavior of materials under contact loads; as a consequence, these methods may not be accurate to predict f...

Abstract Conventional manipulators with rigid structures and stiffness actuators have poor flexibility, limited obstacle avoidance capability, and constrained workspace. Some developed flexible or soft manipulators in re...

Abstract Current studies of a seawater axial piston pump mainly solve the problems of corrosion and wear in a slipper pair by selecting materials with corrosion resistance, self-lubrication, and wear resistance. In addit...

Abstract High-dispersed nanoscale Cu precipitates often contribute to extremely high strength due to precipitation hardening, and whereas usually lead to degraded toughness for especially ferritic steels. Hence, it is im...

Abstract Complicated tribological behavior occurs when human fingers touch and perceive the surfaces of objects. In this process, people use their exploration style with different conditions, such as contact load, slidin...

Abstract Laser powder bed fusion (LPBF) is an advanced manufacturing technology; however, inappropriate LPBF process parameters may cause printing defects in materials. In the present work, the LPBF process of Ti-6.5Al-3...

Abstract The emergence of connected and automated vehicles (CAV) indicates improved traffic mobility in future traffic transportation systems. This study addresses the research gap in macroscopic traffic modeling of mixe...

Abstract Lubrication failure is one of the main failure forms of gear failure. Time varying meshing stiffness is an important factor affecting the dynamic behavior of gears. However, the influence of oil film stiffness i...

Environmental and health concerns about lead-based materials have increased the need for high-density, lead-free alternatives for fishing weights, hunting bullets, ammunition, and body armor applications. Brass/40 wt.%...

Spherical crystallization (SC) is a promising alternative for improiving micromeritic properties and dissolution rate of active pharmaceutical ingredients. In the present work spherical agglomerates of carvedilol (CAR) w...

This study began with the premise that people can use varying degrees of their selves, physically, cognitively, and emotionally, in work role performances, which has implications for both their wor...

O objetivo deste trabalho foi verificar a viabilidade do revestimento pelicular de comprimidos contendo alto teor de produto seco por aspersão (PSA) de Phyllanthus niruri visando proteção frente à variações atmos...

La clave para el éxito de las formulaciones de Compresión Directa está muy asociada con el comportamiento funcional de los excipientes, particularmente con los rellenos. Sin aglutinantes rellenos con buena fluidez y...

El poliestireno (PS) y las poliolefinas (PO) tales como el polietileno (PE) y el polipropileno (PP), son componentes mayoritarios de los residuos plásticos urbanos. Reciclarlos conjuntamente, evitando la separación pre...

The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy (60meV) which could lead to lasing action based on exciton recombination even above room...

We measured the elastic properties and intrinsic breaking strength of free-standing monolayer graphene membranes by nanoindentation in an atomic force microscope. The force-displacement behavior is interpreted within a f...
