Motor speed control system design considering a trade-off between response speed and noise reduction

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This paper proposes an automatic tuning method for a motor speed control system. Parameters of a PI controller and a low-pass filter (LPF) for motor speed signal are automatically derived satisfying required specifications of a time constant of step ...

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Effects of Wind Barrier Porosity and Inclination on Wind Speed Reduction

open access: yesApplied Sciences, 2023
Wind barriers play a vital role in protecting saplings until maturity when planted as vegetative windbreak forests. Most previous studies have focused on the porosity of wind barriers, but no studies have simultaneously examined the effects of the ...

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

The effectiveness of new 3D visual effect speed hump in speed reduction

open access: yesMATEC Web of Conferences, 2018
Intersection is a function of parsing and altering traffic movement. The safety of vehicle manoeuvres at the junction depends on the minimum speed. The purpose of this study is to identify the effectiveness of the usage of temporary speed hump (3D visual

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Dazzle camouflage affects speed perception [PDF]

open access: yes, 2011
Movement is the enemy of camouflage: most attempts at concealment are disrupted by motion of the target. Faced with this problem, navies in both World Wars in the twentieth century painted their warships with high contrast geometric patterns: so-called ...

High Speed Level Converters With Short Circuit Current Reduction

open access: yesInternational Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2014
The level converter is used as interface between low voltages to high voltage boundary. The efficient level converter has less power consumption and less delay are the design considerations of the level shifter.
