Cap‐oPMN: Oral Inflammatory Load Quantification Using Capillary Microfluidics and Automated Image Processing

Advanced Materials Technologies, EarlyView.
ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

Force Control of Hydraulic Actuators using Additional Hydraulic Compliance

Strojniški vestnik - Journal of Mechanical Engineering, 2018
This paper presents an approach for improving the performance of hydraulic force control systems by adding hydraulic compliance. Typically, force control systems require a flexible coupling system, such as a spring between the actuator and the load, to achieve a non-oscillatory response.

Adaptive sliding-mode delay compensation for real-time hybrid simulations with multiple actuators

Frontiers in Built Environment
Real-time hybrid simulation (RTHS) is a widely applied test method in structural engineering, which is developed from pseudo-dynamic test. Much of the past work has been centered on one-dimensional RTHS using a single hydraulic actuator.
