Obstacle Detection in Infrared Navigation for Blind People and Mobile Robots
Autor: Ioannis Papagianopoulos, Gilbert De Mey, Andrzej Kos, Boguslaw Wiecek, Vasilis Chatziathasiou
Publikováno v: Sensors, Vol 23, Iss 16, p 7198 (2023)
The paper is a continuation of the authors’ work intended for infrared navigation for blind people and mobile robots. This concerns the detection of obstacles in the person’s or mobile robot’s trajectory, in particular, the detection of corners

Thermal Characterization of Electronic Components Using Single-detector IR Measurement and 3D Heat Transfer Modelling
Autor: Boguslaw Wiecek, M. Kopeć
Publikováno v: MIXDES
A novel methodology of thermal impedance measurement by temperature monitoring out of the heat source in a power transistor is presented. A low-cost Infra-Red (IR) head is used to register evolution of temperature after step-function powering. A dedi

The Application of NIR Spectrometer for Average Temperature Measurement in Optical Fibers Based on Spontaneous Raman Scattering for DTS Applications
Autor: Boguslaw Wiecek, I. S. M. Shatarah
Publikováno v: MIXDES
Scopus-Elsevier
Continuously excited Raman scattering in optical fibers is proposed for temperature remote sensing in a Distributed Temperature Sensing (DTS) system. Such an approach is suitable for average temperature measurements over the entire optical fiber or i

Thermal modelling and screening method for skin pathologies using active thermography
Autor: R. Strąkowski, Michal Strzelecki, Boguslaw Wiecek, M. Strąkowska, Gilbert De Mey
Publikováno v: Biocybernetics and Biomedical Engineering. 38:602-610
This paper presents a novel screening approach of human skin pathologies using Active IR Thermography. The inputs of the proposed algorithm are the values of the physical parameters of the skin. Parameters are estimated based on dynamic thermographic

Fringing-Effect Losses in Inductors by Thermal Modeling and Thermographic Measurements
Autor: Boguslaw Wiecek, Rafal Sylwester Kasikowski
Publikováno v: IEEE Transactions on Power Electronics. 36:9772
The fringing-field phenomenon can have a significant impact on power loss and temperature distribution in windings of magnetic components with an air gap. The magnetic flux in a core does not cross the air gap in straight lines, but fringes out into
