An algebraic analytical approach for redundant parameter analysis of serial and parallel mechanisms

Redundant parameter analysis is crucial for the kinematic calibration of mechanisms. To address this challenge, the paper proposes an analytical redundant parameter analysis approach based on physical-to-algebraic transformation for both serial and parallel mechanisms. First, sin...

A review of heating mechanisms, process parameters, and defect-minimized densification applications of microwave sintering in metals

Microwave sintering, an advanced materials processing technique, has garnered substantial attention due to its distinctive heating mechanism, which facilitates more uniform and efficient heating of materials, such as metal powders. This study constructs a comprehensive analytical...

Structural Designof AlGaN Deep-Ultraviolet Laserat Wavelength 266.3 nm with Graded Electron Blocking Layer and CompositeQuantum Wells/Barriers

Abstract Deep-ultraviolet laser diodes (DUV LDs) are developing as vigorous light sources for sterilization, lithography, purification, and biochemical sensing. However, the development of high-performance deep-UV laser diodes is still limited by poor hole injection, which comes...
