Profiling Co‐Occurrent Morphological Phenotypes and Their Degree of Expression Severity in Vacuolated Cells by Holo‐Tomographic Flow Cytometry and Fractal Analysis

Advanced Intelligent Systems, EarlyView.
HTFC gets 3D refractive index tomograms of flowing cells. Label‐free monocytes are engineered to express patterns of cytoplasmic vacuoles. From the tomogram, an efficient dimensionality reduction is operated. Interpretable features are extracted to classify the expression severity of phenotypes coexisting in each cell, visually represented by a seven ...

Deterministic identification of lossless and dissipative systems

, 2010
We illustrate procedures to identify a state-space representation of a passive or bounded-real system from noise-free measurements. The basic idea underlying our algorithms is to obtain a state sequence from a rank-revealing factorization of a Gramian ...

Recursive subspace identification algorithm using the propagator based method [PDF]

, 2017
Subspace model identification (SMI) method is the effective method in identifying dynamic state space linear multivariable systems and it can be obtained directly from the input and output data. Basically, subspace identifications are based on algorithms

SSI improved algorithm based on zero phase filtering technology for structural parameter identification in civil engineering [PDF]

Archives of Civil Engineering
Early damage detection and reinforcement of civil engineering structures are crucial. To ensure timely maintenance in the later stage, the civil structure is subjected to modal parameter identification.

Subspace-based damage identification of roller bearing

MATEC Web of Conferences, 2015
This study presents a frequency-band subspace-based damage identification method for faults diagnosis in roller bearing. The main purpose is to obtain damage sensitive indicators in the frequency range where a damage is expected to appear.

Comparative Study Between Three Subspace Identification Algorithms

, 1998
Since the appearance of subspace system identification in literature different subspace algorithms are available in practice. The most commonly used algorithms are CVA, N4SID and MOESP.

A Subspace Based Instrumental Variable Method for State-Space System Identification

, 1994
Traditional prediction-error techniques for multivariable system identification require canonical descriptions using a large number of parameters. This problem may be avoided using subspace based methods, since these estimate a state-space model directly

Deterministic-Stochastic Subspace Identification of the Modal Parameters of a Machine Tool During Milling

Journal of Manufacturing and Materials Processing
Modal analysis is a standard tool for evaluating the dynamic behaviour of machine tools. Since the dynamic behaviour can differ for operating and analysis conditions, the use of operational modal analysis for machine tools has been researched over the ...
