We present the four key areas of research—preprocessing, the volume conductor, the forward problem, and the inverse problem—that affect the performance of EEG and MEG source imaging. In each key area we identify prominent approaches and methodologies that have open issues warranting further investigation within the community, challenges associated with certain techniques, and algorithms necessitating clarification of their implications. More than providing definitive answers we aim to identify important open issues in the quest of source localization.

CMOS planar spiral inductor modeling and low noise amplifier design Telli, A; Demir, S; Askar, M (Elsevier BV, 2006-01-01) During this study, various narrowband single-ended inductive source degenerated Low Noise Amplifiers (LNAs) for GSM and S-band low earth orbit (LEO) space applications have been designed, simulated and compared using Mietec CMOS 0.7 mu m process and the Cadence/BSIM3v3. To get more realistic results, parasitic effects due to layout have been calculated and added to the simulations. Also, considering the inductive source degenerative topology, most of the attention is given on the modeling of planar spiral i...
Sensorless control of a three-degree-of-freedom ultrasonic vibration tool holder Gao, Jian; Çalışkan, Hakan; Altintas, Yusuf (Elsevier BV, 2019-07-01) Piezoelectric actuators are commonly used to deliver vibrations with an amplitude range of (5 mu m-25 mu m) at ultrasonic frequencies (>= 15 kHz) in machining applications. The natural frequencies of ultrasonic vibration actuators vary under the varying cutting force disturbances during machining. Consequently, the amplitudes of delivered vibrations deviate from the desired reference values. As opposed to using vibration sensors, this paper presents a sensorless method to track and control the frequency and...
Quadrature error compensation and its effects on the performance of fully decoupled MEMS gyroscopes Tatar, Erdinç; Akın, Tayfun; Department of Electrical and Electronics Engineering (2010) This thesis, for the first time in the literature, presents the effect of quadrature error compensation on the performance of a fully decoupled MEMS gyroscope and provides experimental data on the sources of quadrature error. Dedicated quadrature error cancellation electrodes operating with only differential DC potentials are designed. Gyroscopes with intentionally placed imperfections are fabricated with SOG based SOI process which provides higher yield and uniformity compared to SOG process. Tests show th...
Fast cell determination of the DSMC molecules in multi-stage turbo molecular pump design Sengil, N.; Edis, Fırat Oğuz (Elsevier BV, 2011-06-01) In this study, an existing 2D parallel DSMC solver is modified, to analyze the multi-stage turbomolecular pumps more efficiently. Generally, molecule movements are traced cell-by-cell in DSMC solvers both in structured and unstructured meshes in order to determine which cell the DSMC molecule is positioned in. These calculations require time consuming trigonometric operations. If a nonrectangular physical domain can be converted into a rectangular computational domain using curvilinear coordinates, then it ...
MHD flow and heat transfer in a lid-driven porous enclosure Pekmen, B.; Tezer, Münevver (Elsevier BV, 2014-01-20) The mixed convection flow in a lid-driven square cavity filled with a porous medium under the effect of a magnetic field is studied numerically using the dual reciprocity boundary element method (DRBEM) with Houbolt time integration scheme. Induced magnetic field is also taken into consideration in terms of magnetic potential in solving magnetohydrodynamic (MHD) flow and temperature equations. Effects of the characteristic dimensionless parameters as Darcy (Da), Magnetic Reynolds (Rem), Grashof (Gr) and Har...
