Contact Force Estimation in Human–Robot Collaboration: A Case Study on Heavyweight Robotic Manipulators

Advanced Intelligent Systems, EarlyView.
The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Energy harvesting potential using a novel hybrid bladeless-Savonius wind turbine

Energy Reports
This study investigates experimentally a novel hybrid wind energy system combining a bladeless wind turbine (BWT) with a Savonius rotor. While both technologies have been extensively studied in isolation, their aerodynamic interaction remains largely ...

Influence Mechanism of Structural Parameters of a Novel Sleeve‐Shaft Counterrotating Hydrodynamic Cavitation Reactor on Cavitation Characteristics and Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

Cryo‐EM Analysis of Adenovirus Vector Reveals Purification Conditions Leading to Loss of Viral Fiber Proteins and Reduced Infectivity

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Vaccines and gene therapies require efficient delivery of genetic material to host cells. Viral vectors leverage viruses' ability to enter host cells to achieve this. Following the SARS‐CoV‐2 vaccine and novel gene therapies that utilize adenovirus vectors, there has been an increase in the demand for large‐scale production of vectors.
