Let’s Make Ball Balancing Great Again: Why You Should Use Temporary Speed Reduction
Machines, 2020 Automatic ball balancing is a technique adopted in rotordynamics to reduce unknown rotor unbalance automatically. This technique sounds appealing as it can ease a panoply of balancing issues considerably.

Speed Bumps Impact on Motor Transport Noise
The Baltic Journal of Road and Bridge Engineering, 2015 Most accidents are caused by excessive speed or aggressive driver behavior. One of the most popular speed regulation implement is speed bumps. However, there are some problems with speed bumps as well – it has been noticed that speed bumps increase motor

Combined methods for torque variation reduction of high-speed FSPM
Energy Reports, 2023 Flux switching permanent magnet machine (FSPM) with six slots and four poles (6/4) shows great potential for high-speed operation. However, the 6/4 FSPM suffers from high cogging torque at no load and loaded torque variation.

Design and implementation of speed fluctuation reduction for a ball screw feed system at low-speed operation [PDF]
Mechanical Sciences, 2020 In the high-precision servo feed system, when the permanent magnet synchronous motor (PMSM) is operated at low speed in the classical drive feed system (CDFS), the speed fluctuation caused by the motor torque harmonics seriously affects the speed ...

ANALYSIS OF TRAVEL TIME DELAY FOR LARGE TSUNAMIS ACROSS THE PACIFIC AND INDIAN OCEANS [PDF]
Science of Tsunami Hazards, 2018 Travel time delay for a tsunami has been an increasingly important issue in recent years. The delay in time is calculated from a difference in arrival times between simulated waveforms and waves recorded by DART and gauge stations.

Operational temporary speed reductions on the ETCS-DMI [PDF]
WIT Transactions on The Built Environment, 2016 Dealing with congested railway area becomes an important topic in railway operation management. Significant efforts are made to develop Driver Advisory System (DAS) in connection with the trackside Train Management System (TMS). Many advantages are expected from smoothing train dynamic speed profiles: timetable resilience, significant reduction of both

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.
