Development of high-acceleration moving table for machine tools (Evaluation of high speed motion of tandem table arranged on same axis)

Nihon Kikai Gakkai ronbunshu, 2014
A new NC tandem table unit driven by linear motor has been developed for machining curved surfaces by turning. This turning method enables to machine the non-axisymmetric curved surfaces with high speed motion synchronizing with the spindle rotation. The

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Braking Force Control for Direct-Drive Brake Units Based on Data-Driven Adaptive Control

Machines
To address the increasing demands for faster response and higher control accuracy in the braking systems of electric and intelligent vehicles, a novel brake-by-wire actuation unit and its braking force control methods are proposed.

Development of a CNC lathe with tandem moving table for high speed turning (Evaluation of high-speed motion and effect of vibration transmission suppression)

Nihon Kikai Gakkai ronbunshu, 2015
A new CNC lathe with a tandem table unit driven by two linear motors has been developed for machining non-axisymmetric curved surfaces by turning. This lathe, which equips 4 axes (X1 X2, Z and C), enables to realize the NACS-turning (Non-Axisymmetric ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

End effects in linear tubular motors and compensated position sensorless control based on pulsating voltage injection [PDF]

, 2011
The sensorless position control of permanent-magnet (PM) synchronous motors can be successfully implemented by superimposing a high-frequency voltage signal on the control voltage.

Design and Control of New Brake-by-Wire Actuator for Vehicle Based on Linear Motor and Lever Mechanism

IEEE Access, 2021
The brake-by-wire actuator was considered to be the next generation of vehicle brake, which uses cables to transmit signals and energy, and uses electric motor instead of hydraulic element or pneumatic element.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A New Approach to Detect Mover Position in Linear Motors Using Magnetic Sensors

Sensors, 2015
A new method to detect the mover position of a linear motor is proposed in this paper. This method employs a simple cheap Hall Effect sensor-based magnetic sensor unit to detect the mover position of the linear motor.
