Omni-Directional Scanning Localization Method of a Mobile Robot Based on Ultrasonic Sensors

open access: yesSensors, 2016
Improved ranging accuracy is obtained by the development of a novel ultrasonic sensor ranging algorithm, unlike the conventional ranging algorithm, which considers the divergence angle and the incidence angle of the ultrasonic sensor synchronously.

Optical fiber sensor for ultrasonic detection at high temperature

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Because of the stable material property of optical fiber up to 1000℃, fiber-optic Bragg grating (FBG) sensor is considered as one of possible ultrasonic sensors used at ultrahigh temperature.

Obstacle Avoidance of Multi-Sensor Intelligent Robot Based on Road Sign Detection

open access: yesSensors, 2021
The existing ultrasonic obstacle avoidance robot only uses an ultrasonic sensor in the process of obstacle avoidance, which can only be avoided according to the fixed obstacle avoidance route. Obstacle avoidance cannot follow additional information.

Intelligent Operator‐Independent Flexibility in Robotic Non‐Destructive Evaluation

open access: yesAdvanced Intelligent Systems
The non‐destructive evaluation (NDE) of high‐value components is commonly regarded as a bottleneck in the manufacturing industry. Even though robotic automation is leveraged these days to accelerate the process, productivity is still hindered by the ...

A method of precise measurement of air speed in mine ventilatio

open access: yesGong-kuang zidonghua, 2014
In view of problem that it is hard to precisely measure time of pulse arriving at receiving sensor due to presence of start-up process when ultrasonic sensor receives ultrasonic pulse signal, the paper proposed a method of precise measurement of air ...

Object recognition with ultrasonic sensors [PDF]

open access: yesProceedings 1999 IEEE International Symposium on Computational Intelligence in Robotics and Automation. CIRA'99 (Cat. No.99EX375), 2003
We have recently introduced a novel approach to sonar based object recognition for robotics. The sonar recognition system, consisting of a Polaroid sonar coupled with art A/D data acquisition board in a LINUX-based PC, uses a fuzzy ARTMAP neural network classification system to recognize objects at varying distances.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
