Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... Mehr lesen

Modeling of Electro-Thermal Microbolometer for Thermal Imaging

A. Nowicki [1], A. Bennecer [1],
[1] Mechanical Engineering, University of Northampton & Gdańsk University of Technology, Gdańsk, Poland
[2] Engineering, University of Northampton, Northampton, United Kingdom

A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... Mehr lesen

[1] Department of Informatics and Telecommunications Engineering, University of Western Macedonia, Kozani, Greece
[2] Department of Mechanical Engineering, University of Western Macedonia, Kozani, Greece

In the context of non-destructive evaluation methods, eddy-current testing plays a prominent role in crack-detection problems, due to its various attractive features. One of the physical quantities that typically interest us in such type of problems is the – complex – coil impedance and ... Mehr lesen

Numerical Calculation of the Three Dimensional Inter-Bar Current Distribution in Induction Machines

J. Güdelhöfer [1], R. Gottkehaskamp [1], A. Möckel [2],
[1] University of Applied Sciences Düsseldorf, Düsseldorf, Germany
[2] Technical University of Ilmenau, Ilmenau, Germany

The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... Mehr lesen
