Shell analysis of elliptical guard cells in higher plants: a review
Shell analysis elliptical guard cells higher plants
2015/8/27
This presentation reviews finite element shell analyses (linear and nonlinear, isotropic and anisotropic) of microscopic stomata modeled as doubly-elliptic toroidal shells. Stomata are the regulating ...
LEAST-SQUARES MATCHING USING ELLIPTICAL AREAS: RESULTS, ACCURACY, ADVANTAGES AND DISADVANTAGES
DTM/DEM quality reliability
2015/6/1
The use of a square template in least squares image matching has been established as a well known and tested method. This paper
suggests the use of an elliptical template as alternative to the squar...
Reliability of the Elliptical Zone Method of Estimating Body Segment Parameters of Swimmers
Anthropometry elliptical zone error inverse dynamics reliability Paralympic swimming
2015/5/26
Due to the difficulty of measuring forces and torques acting on a swimmer during mid-pool swimming, an inverse dynamics approach is required. Personalised body segment parameter (BSP) data enabling ca...
Familiarization Effects of an Elliptical All-out Test and the Wingate Test Based on Mechanical Power Indices
Adaptation anaerobic coordination practice reliability Wingate
2015/5/18
The Wingate all-out test (WAT) is commonly used to estimate anaerobic capabilities of athletes by using an upper or lower body cycle ergometer, however, a new test modality called elliptical all-out t...
Relationship Between %Heart Rate Reserve And %VO Reserve During Elliptical Crosstrainer Exercise
Exercise mode regression exercise prescription
2015/3/23
The primary purpose of the study was to determine the relationships between %HRR vs. %VO2R and %HRR vs. %VO2max during maximal elliptical crosstrainer (ECT) exercise. A secondary aim was to compare th...
Confronting feedback simulations with observations of hot gas in elliptical galaxies
X-ray elliptical galaxies hot gas galaxy evolution
2014/12/23
Elliptical galaxies comprise primarily old stars, which collectively generate a long-lasting feedback via stellar mass-loss and Type Ia SNe. This feedback can be traced by X-ray-emitting hot gas in an...
Analysis of elliptical copula correlation factor model with Kendall's tau
Elliptical copula correlation matrix factor model Kendall’s tau nuclear norm penalty oracle inequality primal-dual certificate
2013/6/14
We study a factor model for the correlation matrix $\Sigma\in\RR^{d\times d}$ of an elliptical copula. The correlations are connected to Kendall's tau and a natural estimation procedure is to plug-in ...
