Numerical Methods for Two-Dimensional Stem Cell Tissue Growth. [PDF]
, 2013 Growth of developing and regenerative biological tissues of different cell types is usually driven by stem cells and their local environment. Here, we present a computational framework for continuum tissue growth models consisting of stem cells, cell ...

ROBUST MOSAICKING OF UAV IMAGES WITH NARROW OVERLAPS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 This paper considers fast and robust mosaicking of UAV images under a circumstance that each UAV images have very narrow overlaps in-between. Image transformation for image mosaicking consists of two estimations: relative transformations and global ...

On the accuracy of compressibility transformations
Physics of FluidsThis study highlights the importance of satisfying the eddy viscosity equivalence below the logarithmic layer, to deriving accurate compressibility transformations. First, we analyze the ability of known transformations to satisfy the eddy viscosity equivalence and show that the accuracy of these transformations is strongly dependent on this ability ...

Transformation invariance in hand shape recognition [PDF]
, 2006 In hand shape recognition, transformation invariance is key for successful recognition. We propose a system that is invariant to small scale, translation and shape variations.

Multi-Fault Diagnosis of Interacting Multiple Model Batteries Based on Low Inertia Noise Reduction
IEEE Access, 2021 In view of the problems of declined estimation and diagnostic accuracy, as well as diagnosis delay caused by the fixed model transformation probability of the interacting multiple model (IMM) fault diagnosis algorithm, an IMM algorithm based on low ...

Factors Influencing Measurement Accuracy of Electronic Transformers [PDF]
Proceedings of the 2015 International Symposium on Material, Energy and Environment Engineering, 2015 With the development of smart grid in our country, as the key devices of the digital metering system, the conversion accuracy and stability of electronic transformer plays a dominant role in the whole metering system error control, the stability and reliability of the electronic transformer is related to the settlement of fair trade. But as a result of

The Magnus expansion and the in-medium similarity renormalization group
, 2015 We present an improved variant of the in-medium similarity renormalization group (IM-SRG) based on the Magnus expansion. In the new formulation, one solves flow equations for the anti-hermitian operator that, upon exponentiation, yields the unitary ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between
