Parameter Identification of PMSM with Finite-difference-based Strong Tracking H∞ Filter

Journal of Harbin University of Science and Technology
The tracking maneuver process accuracy of traditional H∞ filter is not enough for high precision control fields. A finite difference-based strong tracking H∞ filter (FD-STHF) is proposed for permanent magnet synchronous motor ( PMSM), which can improve ...

Large Margin Object Tracking with Circulant Feature Maps

, 2017
Structured output support vector machine (SVM) based tracking algorithms have shown favorable performance recently. Nonetheless, the time-consuming candidate sampling and complex optimization limit their real-time applications.

Fingers of a Hand Oscillate Together: Phase Syncronisation of Tremor in Hover Touch Sensing [PDF]

, 2016
When using non-contact finger tracking, fingers can be classified as to which hand they belong to by analysing the phase relation of physiological tremor.

The Photospheric Poynting Flux and Coronal Heating [PDF]

, 2014
Some models of coronal heating suppose that convective motions at the photosphere shuffle the footpoints of coronal magnetic fields and thereby inject sufficient magnetic energy upward to account for observed coronal and chromospheric energy losses in ...

Decorrelation Times of Photospheric Fields and Flows

, 2012
We use autocorrelation to investigate evolution in flow fields inferred by applying Fourier Local Correlation Tracking (FLCT) to a sequence of high-resolution (0.3 \arcsec), high-cadence ($\simeq 2$ min) line-of-sight magnetograms of NOAA active region ...

Ideal gas behavior of a strongly-coupled complex (dusty) plasma [PDF]

, 2013
In a laboratory, a two-dimensional complex (dusty) plasma consists of a low-density ionized gas containing a confined suspension of Yukawa-coupled plastic microspheres.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Towards a Principled Integration of Multi-Camera Re-Identification and Tracking through Optimal Bayes Filters

, 2017
With the rise of end-to-end learning through deep learning, person detectors and re-identification (ReID) models have recently become very strong. Multi-camera multi-target (MCMT) tracking has not fully gone through this transformation yet.

Analysis of Ionospheric Scintillations using Wideband GPS L1 C/A Signal Data [PDF]

, 2004
A non-real-time GPS receiver has been developed and tested for use in scintillation analysis. The receiver consists of a digital storage receiver and non-real-time software acquisition and tracking algorithms.
